FIELD OF THE INVENTION

The present disclosure is concerned with a storage case for storing a power-driven personal care implement, the storage case comprising a primary cavity, a primary cover, a secondary cavity, and a secondary cover. The primary cavity and the primary cover define a primary compartment, while the secondary cavity and the secondary cover define a secondary compartment separate from the primary compartment. The present disclosure is further concerned with a personal care kit comprising such storage case.

BACKGROUND OF THE INVENTION

Storage cases for storing power-driven personal care implements, like power-driven toothbrushes, power-driven shavers, and power-driven epilators, are well known in the art. Generally, power-driven personal care implements require a power source, such as a battery, to operate. Storage cases known in the art are suitable to store power-driven personal care implements. However, such storage cases are not adapted to store the power source independent from the power-driven personal care implement.

Storage cases known in the art may comprise a battery that is utilized for various functions other than powering the power-driven personal care implements. For example, the battery may be utilized to power an ultra-violet (UV) light for disinfecting the power-driven personal care implement stored in the storage case. In other words, the battery housed in such storage cases is generally not connected to the power-driven personal care implement itself to power the implement.

Usually, the power source powering the power-driven personal care implement is stored and carried separately from the storage cases by a user during travel. However, separately storing and carrying the power source may cause inconvenience to the user during travel. In addition, the power source stored separately from the storage cases may get misplaced or lost during travel, causing further inconvenience. In some instances, the user may also need to carry spare power sources for the power-driven personal care implements during travel. Storing the spare power sources separately, or procuring the spare power sources during travel may be inconvenient and impractical for the user.

Storing the power source together with the power-driven personal care implement in one compartment may potentially result in a short-circuit of the power source, for example, due to the presence of contaminants within the compartment, such as moisture and/or any other electrically conductive material. For instance, water along with any additional material, such as toothpaste, could be introduced into the compartment if the power-driven personal care implement is not sufficiently cleaned and dried after use. Water may come into contact with the power source and act as an electrical conductor, thereby short circuiting positive and negative terminals or poles of the power source. This may result in discharge of the power source, and in some cases, may pose electrical hazard to the user.

Therefore, there is a need for a storage case that is suitable for storing a power-driven personal care implement along with a power source , so that that the power source does not suffer any damage or short-circuit during storage, for example, due to contact with any contaminants.

It is an object of the present disclosure to provide a storage case for storing a power-driven personal care implement which overcomes at least one of the above-mentioned drawbacks. It is also an object of the present disclosure to provide a personal care kit comprising such storage case.

DETAILED DESCRIPTION OF THE INVENTION

A storage case for a power-driven personal care implement according to the present disclosure comprises a primary cavity and a primary cover. The primary cavity and the primary cover define a primary compartment configured to store the power-driven personal care implement therein. In the context of this disclosure, the term “power-driven personal care implement” refers to any implement which can be utilized for the purposes of personal care and is powered by a power source, such as a battery. Examples of the power-driven personal care implement include power-driven toothbrushes, power-driven razors, power-driven epilators, and the like.

The primary cover is configured to set the primary compartment in an open or a closed position. In other words, the primary cover may be movable to an open cover position to set the primary compartment in the open position, i.e., a state of the primary compartment in which the power-driven personal care implement may be accessed by a user. Therefore, in the open position, the power-driven personal care implement can be removed from the primary compartment. The primary cover may further be movable to a closed cover position to set the primary compartment in the closed position, i.e., a state of the primary compartment in which the power-driven personal care implement may not be accessible by a user. In the closed position, the power-driven personal care implement may be securely stored within the primary compartment and cannot be removed or ejected from the primary compartment even if the storage case undergoes any movement (e.g., jerks or rotations).

The primary cover may be configured to set the primary compartment in the open position or the closed position by any suitable mechanism, such as a snap-fit. Specifically, the primary cover and the primary cavity may comprise complementary primary interlocking features, such that the primary cover may be attachable to and detachable from the primary cavity. In some examples, the primary cover may be fully detachable from the primary cavity after the complementary primary interlocking features are unlocked or unlatched. However, the primary cover is preferably movably connected to the primary cavity. In other words, the primary cover is preferably configured to move relative to the primary cavity, while staying mechanically connected to the primary cavity. Therefore, the primary cover may not get misplaced or lost during travel. In some cases, the primary cover is movably connected to the primary cavity in addition to the complementary primary interlocking features. The complementary primary interlocking features may detachably secure the primary cover to the primary cavity in the closed position. Moreover, the primary cover can be moved relative to the primary cavity after unlocking or unlatching the complementary primary interlocking features. For example, after unlocking the complementary primary interlocking features, the primary cover can be moved to the open cover position to set the primary compartment in the open position. The relative movement between the primary cavity and the primary cover may be linear, curvilinear, rotational, or a combination thereof.

The storage case further comprises a secondary cavity and a secondary cover. The secondary cavity and the secondary cover define a secondary compartment separate from the primary compartment. The secondary compartment is configured to store a power source electrically unconnected to any electrical conductors. In other words, the secondary compartment is free of any electrical conductors. In the context of this disclosure, an electrical conductor is defined as any type of object or material allowing flow of electrical current in one or more directions. Further, in the context of this disclosure, the term “power source” refers to any power source which can power the power-driven personal care implement, such as a battery. The power source may be rechargeable or non-rechargeable. Examples of the power source include AA batteries, AAA batteries, 9-volt batteries, and the like.

Therefore, the secondary compartment may store the power source in an electrically- isolated and detached state. The power source, when stored in the secondary compartment, does not supply power to any electrical devices (e.g., a UV light for disinfecting the power-driven personal care implement). In other words, no power may be drawn from the power source when stored in the secondary compartment. Therefore, the power source may substantially retain its charge level. Further, the power source can be removed from the secondary compartment for use with the power-driven personal care implement. In addition, the secondary compartment may be used to store spare power sources (i.e., extra power sources) during travel.

The secondary cover is configured to set the secondary compartment in an open or a closed position. In other words, the secondary cover may be movable to an open cover position to set the secondary compartment in open position, i.e., in a state in which the power source may be accessible by the user. Therefore, in the open position, the power source can be removed from the secondary compartment. The secondary cover may further be movable to a closed cover position to set the secondary compartment in closed position, i.e., in a state in which the power source may not be accessible by the user. In the closed position, the power source can be securely stored within the secondary compartment and cannot be removed or ejected from the secondary compartment even if the storage case undergoes any movement (e.g., jerks or rotations).

The secondary cover may be configured to set the secondary compartment in the open or closed position by any suitable mechanism, such as a snap-fit. Specifically, the secondary cover and the secondary cavity may comprise complementary secondary interlocking features, so that the secondary cover is attachable to and detachable from the secondary cavity. In some examples, the secondary cover may be fully detachable from the secondary cavity after the complementary secondary interlocking features are unlocked or unlatched. However, the secondary cover is preferably movably connected to the secondary cavity. In other words, the secondary cover is preferably configured to move relative to the secondary cavity, while staying mechanically connected to the secondary cavity. Therefore, the secondary cover may not get misplaced or lost during travel.

In some cases, the secondary cover is movably connected to the secondary cavity in addition to the complementary secondary interlocking features. The complementary secondary interlocking features may detachably secure the secondary cover to the secondary cavity in the closed position. Moreover, the secondary cover can be moved relative to the secondary cavity after unlocking or unlatching the complementary secondary interlocking features. For example, after unlocking the complementary secondary interlocking features, the secondary cover can be moved to the open cover position to set the secondary compartment in the open position. The relative movement between the secondary cavity and the secondary cover may be linear, curvilinear, rotational, or a combination thereof.

The secondary compartment may be separated from the primary compartment in a substantially watertight manner. In other words, a wall of the secondary cavity may seal the secondary compartment from the primary compartment in order to prevent a flow of liquid from the primary compartment to the secondary compartment. This may prevent a short-circuit of the power source stored in the secondary compartment. Such short-circuit can otherwise occur due to ingress of liquid from the primary compartment in which the power-driven personal care implement is stored. Separating the primary and the secondary compartment in a watertight manner may prevent contaminants, such as water and toothpaste, entering the secondary compartment from the primary compartment. In one example, the secondary cavity may comprise one or more walls made of an impermeable material, such as polypropylene, to separate the secondary compartment from the primary compartment in a substantially watertight manner. Other examples of impermeable materials include polyethylene, ethylene-vinyl acetate, polyamide, acrylonitrile butadiene styrene, polyoxymethylene, acrylonitrile styrene acrylate, and the like.

The secondary cavity may extend at least partially into the primary compartment to enable a compact design. The storage case may consequently be easy to carry and store.

The primary cavity may comprise a first side wall and a second side wall disposed opposite to the first side wall. Further, the secondary cavity may comprise an edge wall disposed distal to the first side wall and proximal to the second side wall. The primary cover may be movably coupled to the primary cavity at the first side wall, and the secondary cover may be movably coupled to the secondary cavity at the edge wall. In other words, the primary cover and the secondary cover may be movably connected to the storage case opposite to each other. Therefore, movements of the primary cover and the secondary cover may not interfere with each other. The user can easily open the primary cover without accidentally opening the secondary cover, and vice versa.

The primary cavity may further define an opening communicating with the secondary compartment. In some examples, the opening may be defined at the second side wall. The opening may allow moving the secondary cover from the closed cover position to the open cover position to access the secondary compartment without moving the primary cover. In other words, the primary cover and the secondary cover may be movable independently of each other for accessing the respective primary and secondary compartments. Thus, the user may access the primary compartment or the secondary compartment independently of each other, as desired.

The primary cavity may comprise an open front side and a back wall disposed opposite to the open front side. Further, the primary cover may cover the open front side in the closed position, and the secondary cover may be disposed adjacent to the back wall in the closed position of the secondary compartment. Such a configuration may further prevent accidental movement of the primary cover when the secondary cover is moved, and vice versa. Further, the back wall may define a recess to facilitate moving the secondary cover from the closed cover position to the open cover position. Since the primary cover and the secondary cover open from opposing sides (i.e., front and back sides) of the storage case, any accidental entry of liquid or any contaminants from the primary compartment to the secondary compartment may be further prevented when both the primary cover and the secondary cover are opened simultaneously.

The secondary cavity may further comprise a main wall and one or more retaining members extending from the main wall. The one or more retaining members may be configured to removably secure the power source within the secondary compartment. The one or more retaining members may be configured to engage and removably secure the power source within the secondary compartment. In some instances, the one or more retaining members may substantially prevent movement of the power source when stored within the secondary compartment.

The storage case may further comprise a primary hinge joint pivotally connecting the primary cover to the primary cavity, and/or a secondary hinge joint pivotally connecting the secondary cover to the secondary cavity. The primary hinge joint and the secondary hinge joint may be any suitable type of hinge joints, such as barrel hinges, flag hinges, self-closing hinges, living hinges, and the like. The primary hinge joint is preferably a primary flexural hinge and the secondary hinge joint is preferably a secondary flexural hinge. The primary flexural hinge may allow the primary cavity and the primary cover to be integrally formed as one component. Further, the secondary flexural hinge may allow the secondary cavity and the secondary cover to be integrally formed as one component. Advantageously, the primary flexural hinge and the secondary flexural hinge may allow the primary cavity, the primary cover, the secondary cavity, and the secondary cover to be integrally formed as a single component. Thus, the storage case may be easy to manufacture at relatively low costs, and may not require major modifications in existing manufacturing lines.

The storage case may further comprise a primary latch mechanism configured to releasably secure the primary cover to the primary cavity, and/or a secondary latch mechanism configured to releasably secure the secondary cover to the secondary cavity. The primary latch mechanism and the secondary latch mechanism may be of any suitable type, such as a clasp, a snap-fit latch, and the like. The primary latch mechanism may correspond to the complementary primary interlocking features that releasably retain the primary cover to the primary cavity in the closed position. The primary latch mechanism may be provided in addition to the movable connection between the primary cover and the primary cavity. The primary latch mechanism may prevent accidental movement of the primary cover relative to the primary cavity. Specifically, the primary cover may not move from the closed cover position to the open cover position unless the primary latch mechanism is manually unlocked. This may ensure that the power-driven personal care implement stored in the primary compartment may not get misplaced or lost during travel.

Furthermore, the secondary latch mechanism may correspond to the complementary secondary interlocking features that releasably retain the secondary cover to the secondary cavity in the closed position. The secondary latch mechanism may be provided in addition to the movable connection between the secondary cover and the secondary cavity. The secondary latch mechanism may prevent accidental movement of the secondary cover relative to the secondary cavity. Specifically, the secondary cover may not move from the closed cover position to the open cover position unless the secondary latch mechanism is manually unlocked. This may ensure that the power source stored in the secondary compartment may not get misplaced or lost during travel.

The primary cavity, the primary cover, the secondary cavity, and the secondary cover may be unitarily molded in one molding step. The primary cavity, the primary cover, the secondary cavity, and the secondary cover may be integrally formed as one component, e.g. unitarily molded by injection molding, blow molding, compression molding, transfer molding, or any other suitable molding process. Therefore, the storage case may be easy to manufacture at relatively low costs, and may not require major modifications in existing manufacturing lines.

The storage case may be made from a material selected from the following list: polypropylene, polyethylene, ethylene-vinyl acetate, polyamide, acrylonitrile butadiene styrene, polyoxymethylene, acrylonitrile styrene acrylate, and any combinations thereof. Preferably, the storage case may be unitarily made from polypropylene. The materials recited in the list above may be suitable for molding and may be economically feasible. Furthermore, the materials recited in the list above may have the desirable properties, such as impermeability to water, moldability, non-toxicity etc., for making the storage case. The primary compartment may have a maximum length extension extending along a longitudinal axis of the primary compartment and a maximum width extension extending perpendicular to the longitudinal axis of the primary compartment. Further, the secondary compartment may have a maximum length extension extending along a longitudinal axis of the secondary compartment and a maximum width extension extending perpendicular to the longitudinal axis of the secondary compartment. The maximum length extension of the primary compartment may be greater than the maximum length extension of the secondary compartment by a factor of at least two, and/or the maximum width extension of the primary compartment may be greater than the maximum width extension of the secondary compartment by a factor of at least two. In some examples, the maximum length extension of the primary compartment may be greater than the maximum length extension of the secondary compartment by a factor of at least two, at least three, or at least four. Further, the maximum width extension of the primary compartment may be greater than the maximum width extension of the secondary compartment by a factor of at least two, at least three, or at least four.

A ratio between the maximum length extension of the primary compartment and the maximum length extension of the secondary compartment may be advantageously chosen based on a relative length difference between one or more components of the power-driven personal care implement and the power source. Similarly, a ratio between the maximum width extension of the primary compartment and the maximum width extension of the secondary compartment may be advantageously chosen based on a relative width difference between the one or more components of the power-driven personal care implement and the power source. Generally, the one or more components of the power-driven personal care implement may have greater length and/or width relative to the power source. Therefore, such a relative configuration of the primary compartment and the secondary compartment may allow the storage case to have a compact design by reducing or eliminating any redundant space within the storage case.

Moreover, a personal care kit according to the present disclosure comprises the storage case and a power-driven personal care implement, preferably a power-driven oral care implement, and more preferably a power-driven toothbrush. The power-driven personal care implement may be stored in the primary compartment of the storage case.

The power-driven oral care implement may comprise a handle and a head. The head may be repeatedly attachable to and detachable from the handle. Alternatively, head may be permanently connected to the handle. In some instances, the head and the handle may be integrally formed as a unitary component.

The personal care kit may further comprise a power source removably stored within the secondary compartment. The power source may be at least one battery. The power source may alternatively be a plurality of batteries.

Since the secondary compartment is separate from the primary compartment, the power source may be fluidically and electrically isolated from the power-driven personal care implement when stored within the secondary compartment. In case the power-driven personal care implement is a power-driven toothbrush, the specific configuration of the storage case may prevent entry of contaminants adhering to the toothbrush, such as water and/or toothpaste, from the primary into the secondary compartment. Thus, the storage case of the present disclosure may protect the power source from coming into contact with such contaminants, thereby preventing any damage and/or short-circuit of the power source while being stored within the secondary compartment.

The following is a non-limiting discussion of example embodiments of storage cases, personal care kits and parts thereof in accordance with the present disclosure, where reference to the Figures is made.

FIGS. 1 A and IB show a schematic front perspective view and a schematic rear perspective view, respectively, of a storage case 100 for storing a power-driven personal care implement. The storage case 100 may be suitable for storing the power-driven personal care implement while being carried by a user during travel.

The power-driven personal care implement may be any implement that requires power to operate, such as a power-driven toothbrush, a power-driven razor, a power-driven epilator, and the like. The power-driven personal care implement may receive power from any suitable power source. In some examples, the power-driven personal care implement may be a battery-driven implement. That is, the power-driven personal care implement may receive power from one or a plurality of batteries, such as non-rechargeable primary batteries, and rechargeable secondary batteries. Examples of the plurality of batteries include AA batteries, AAA batteries, 9-volt batteries, and the like. The storage case 100 comprises a primary cavity 120 and a primary cover 140. The primary cavity 120 and the primary cover 140 define a primary compartment 122 configured to store the power-driven personal care implement therein. The primary cavity 120 and the primary cover 140 may have any suitable shape and dimensions to store the power-driven personal care implement.

The primary cover 140 is configured to set the primary compartment 122 in an open position 122a or a closed position 122b (shown in FIGS. 1 A, IB, 2A and 2B). The open position 122a of the primary compartment 122 may refer to a state of the primary compartment 122 in which the power-driven personal care implement is accessible. Accordingly, the primary cover 140 may be movable to an open cover position 140a to set the primary compartment 122 in the open position 122a.

Further, the closed position 122b (shown in FIGS. 2 A and 2B) of the primary compartment 122 may refer to a state of the primary compartment 122 in which the power-driven personal care implement may not be removable from the primary compartment 122 by the user. In other words, the user may not be able to access the power-driven personal care implement stored in the primary compartment 122. Accordingly, the primary cover 140 may be movable to a closed cover position 140b (shown in FIGS. 2 A and 2B) to set the primary compartment 122 in the closed position 122b. Thus, the primary cover 140 may be movable between the open cover position 140a and the closed cover position 140b to set the primary compartment 122 in the open position 122a and the closed position 122b, respectively.

The primary cover 140 may be configured to set the primary compartment 122 in the open position 122a or the closed position 122b (shown in FIGS. 1 A, IB, 2A and 2B) by any suitable mechanism. In one example, the primary cover 140 may be attachable to and detachable from the primary cavity 120 by a snap-fit to set the primary compartment 122 in the open position 122a and the closed position 122b, respectively. Accordingly, the primary cover 140 and the primary cavity 120 may comprise complementary primary interlocking features such that the primary cover 140 may be attachable to and detachable from the primary cavity 120. In some examples, the primary cover 140 may be fully detachable from the primary cavity 120 after the complementary primary interlocking features are unlocked or unlatched. However, the primary cover 140 is preferably movably connected to the primary cavity 120, as illustrated in FIGS. 1A and IB. That is, the primary cover 140 may be configured to move relative to the primary cavity 120, while staying mechanically connected to the primary cavity 120. In other words, the primary cavity 120 and the primary cover 140 may be movable relative to each other while remaining connected to each other. Therefore, the primary cover 140 may not get misplaced or lost during travel.

Specifically, the storage case 100 illustrated in FIGS. 1 A and IB comprises a primary hinge joint 125 pivotally connecting the primary cover 140 to the primary cavity 120. The primary hinge joint 125 may be any suitable type of hinge joint, such as a barrel hinge, a flag hinge, a self-closing hinge, a living hinge, and the like. However, the primary hinge joint 125 is preferably a primary flexural hinge 135. Making use of a primary flexural hinge 135 may reduce manufacturing costs of the storage case 100,. as the primary cover 140 and the primary cavity 120 can be manufactured in one molding step.

The primary cavity 120 further comprises an open front side 123 and a back wall 127 disposed opposite to the open front side 123. The user may access the power-driven personal care implement stored in the primary compartment 122 from the open front side 123. Further, the primary cover 140 can cover the open front side 123 in the closed position 122b (shown in FIGS. 2A and 2B). In other words, the primary cover 140 covers the open front side 123 in the closed cover position 140b (shown in FIGS. 2A and 2B). Thus, the user may not be able to access the power-driven personal care implement stored in the primary compartment 122 from the open front side 123 when it is in the closed position 122b.

The primary cavity 120 further comprises a first side wall 126a and a second side wall 126b disposed opposite to the first side wall 126a. The primary cover 140 illustrated in FIGS. 1 A and IB is movably coupled to the primary cavity 120 at the first side wall 126a. Specifically, the primary cover 140 is movably coupled to the primary cavity 120 at the first side wall 126a by the primary hinge joint 125. More specifically, the primary flexural hinge 135 movably couples the primary cover 140 to the first side wall 126a of the primary cavity 120.

Further, the first side wall 126a and the second side wall 126b are connected to the back wall 127. The back wall 127, the first side wall 126a, and the second side wall 126b partially define the primary compartment 122. Further, the back wall 127 may be unitarily formed with the first and second side walls 126a, 126b, thereby forming the primary cavity 120. Moreover, the back wall 127 illustrated in FIGS. 1A and IB may be substantially planar and generally oval in shape. Alternatively, the back wall 127 may have other suitable shapes, such as rectangular, polygonal, and so forth. In some instances, the back wall 127 may be curved. Further, each of the first side wall 126a and the second side wall 126b illustrated in FIGS. 1 A and IB may be curved, or, alternatively, substantially planar.

The primary cavity 120 illustrated in FIG. 1A further comprises a plurality of primary cavity retention features 121 extending from primary cavity 120 into the primary compartment 122. Specifically, each of the plurality of primary cavity retention features 121 extends from one or more of the back wall 127, the first side wall 126a, and the second side wall 126b. The plurality of primary cavity retention features 121 may be configured to removably secure and restrict movement of the power-driven personal care implement when stored in the primary compartment 122. The plurality of primary cavity retention features 121 may further facilitate placement of the power-driven personal care implement in the primary compartment 122. Moreover, the primary cover 140 illustrated in FIG. 1 A further comprises a plurality of primary cover retention features 141. The plurality of primary cover retention features 141 may complement the plurality of primary cavity retention features 121 in removable securement of the power-driven personal care implement in the primary compartment 122 when the primary cover 140 is in the closed cover position 140b (shown in FIG. 2A).

The storage case 100 further comprises a secondary cavity 160 and a secondary cover 180. The secondary cavity 160 and the secondary cover 180 define a secondary compartment 162 separate from the primary compartment 122. The secondary compartment 162 is separated from the primary compartment 122 in a substantially watertight manner. In other words, the secondary cavity 160 is sealed from the primary cavity in order to prevent flow of liquid from the primary compartment 122 to the secondary compartment 162. That is, the secondary cavity 160 may have suitable properties and design to separate the secondary compartment 162 from the primary compartment 122 in the substantially watertight manner. For example, the secondary cavity 160 may comprise one or more walls made from an impermeable material, such as polypropylene. Other examples of impermeable materials include polyethylene, ethylene-vinyl acetate, polyamide, acrylonitrile butadiene styrene, polyoxymethylene, acrylonitrile styrene acrylate, and the like.

The secondary compartment 162 is configured to store a power source electrically unconnected to any electrical conductors. In other words, the secondary compartment 162 is free of any electrical conductors. In the context of this disclosure, an electrical conductor is defined as any type of object or material allowing flow of electrical current in one or more directions. Therefore, when stored in secondary compartment 162, the power source does not supply power to any electrical devices (e.g., a UV light, the power-driven personal care implement, and the like). In other words, no power is drawn from the power source when stored in the secondary compartment 162. As such, the power source may substantially retain its charge level when stored in the secondary compartment 162. In some examples, the secondary compartment 162 may be configured to store a plurality of power sources, e.g., a plurality of batteries. In some examples, dimensions of the secondary cavity 160 and the secondary cover 180 may depend on the type and number of the power source. In some examples, the power source may be one or more spare batteries, i.e., extra batteries for powering the power-driven personal care implement.

Moreover, the secondary cavity 160 illustrated in FIG. 1 A extends at least partially into the primary compartment 122, thereby enabling a compact design. The storage case 100 may consequently be easy to carry and store within a limited space.

The secondary cover 180 is configured to set the secondary compartment 162 in an open position 162a or a closed position 162b (shown in FIGS. IB and 2B). The open position 162a of the secondary compartment 162 may refer to a state of the secondary compartment 162 in which the power source may be accessible by the user. Accordingly, the secondary cover 180 may be movable to an open cover position 180a to set the secondary compartment 162 in the open position 162a.

Further, the closed position 162b (shown in FIG. 2B) of the secondary compartment 162 may refer to a state of the secondary compartment 162 in which the power source may not be removed from the primary compartment 122 by the user. In other words, the user may not be able to access the power source stored in the secondary compartment 162 in the closed position 162b. Accordingly, the secondary cover 180 may be movable to a closed cover position 180b (shown in FIG. 2B) to set the to set the secondary compartment 162 in the closed position 162b. Thus, the secondary cover 180 may be movable between the open cover position 180a and the closed cover position 180b to set the to set the secondary compartment 162 in the open position 162a and the closed position 162b, respectively.

The secondary cover 180 may be configured to set the secondary compartment 162 in the open position 162a or the closed position 162b (shown in FIGS. IB and 2B) by any suitable mechanism. In one example, the secondary cover 180 may be attachable to and detachable from the secondary cavity 160 by a snap-fit to set the secondary compartment 162 in the open position 162a and the closed position 162b, respectively. Accordingly, the secondary cover 180 and the secondary cavity 160 may comprise complementary secondary interlocking features such that the secondary cover 180 may be attachable to and detachable from the secondary cavity 160. In some examples, the secondary cover 180 may be fully detachable from the secondary cavity 160 after the complementary secondary interlocking features have been unlocked or unlatched. However, the secondary cover 180 is preferably movably connected to the secondary cavity 160, as illustrated in FIGS. 1A and IB. That is, the secondary cover 180 may be configured to move relative to the secondary cavity 160, while staying mechanically connected to the secondary cavity 160. In other words, the secondary cavity 160 and the secondary cover 180 may be movable relative to each other while remaining connected to each other. Therefore, the secondary cover 180 may not get misplaced or lost during travel.

Specifically, the storage case 100 illustrated in FIGS. 1A and IB comprises a secondary hinge joint 165 pivotally connecting the secondary cover 180 to the secondary cavity 160. The secondary hinge joint 165 may be any suitable type of hinge joint, such as a barrel hinge, a flag hinge, a self-closing hinge, a living hinge, and the like. However, the secondary hinge joint 165 is preferably a secondary flexural hinge 175. Making use of such secondary flexural hinge 175 may reduce manufacturing costsas the secondary cover 180 and the secondary cavity 160 can be manufactured as one piece, thereby reducing associated assembly labor.

FIGS. 2 A and 2B show a schematic front perspective view and a schematic rear perspective view, respectively, of the storage case 100 in a closed position.

In FIGS. 2 A and 2B, the primary compartment 122 and the secondary compartment 162 are shown in closed positions 122b, 162b. . Accordingly, the primary cover 140 is in the closed cover position 140b and the secondary cover 180 is in the closed cover position 140b. As discussed above, the primary cover 140 covers the open front side 123 (shown in FIG. 1A) in the closed position 122b . Furthermore, the secondary cover 180 is disposed adjacent to the back wall 127 in the closed position 162b of the secondary compartment 162. In other words, the secondary cover 180 is disposed adjacent to the back wall 127 in the closed cover position 180b. As shown in FIG. 2B, the secondary cover 180 is substantially flush with the back wall 127 in the closed cover position 180b. Therefore, a back side of the storage case 100 may have a smooth shape without any protrusions in the closed cover position 180b of the secondary cover 180. FIG. 3 A shows an enlarged schematic top front perspective view of a portion of the storage case 100, and FIG. 3B shows an enlarged schematic bottom front perspective view of a portion of the storage case 100.

The secondary cavity 160 illustrated in FIGS. 3A and 3B comprises an edge wall 166 disposed distal to the first side wall 126a and proximal to the second side wall 126b. The secondary cover 180 illustrated in FIGS. 3A and 3B is movably coupled to the secondary cavity 160 at the edge wall 166. Specifically, the secondary cover 180 is movably coupled to the secondary cavity 160 at the edge wall 166 by the secondary hinge joint 165. More specifically, the secondary flexural hinge 175 movably couples the secondary cover 180 to the edge wall 166 of the secondary cavity 160.

The secondary cavity 160 further comprises a main wall 164. The main wall 164 extends from the primary cavity 120. Specifically, the main wall 164 illustrated in FIGS. 3A and 3B comprises a first portion 164a, a second portion 164b, and a third portion 164c. The first portion 164a is connected to and extends from the primary cavity 120. Specifically, the first portion 164a is connected to and extends from of the back wall 127 of the primary cavity 120. The second portion 164b is connected to the edge wall 166. The third portion 164c connects the first portion 164a to the second portion 164b and is partially curved. The secondary cavity 160 illustrated in FIGS. 3A and 3B further comprises a first end wall 167a and a second end wall 167b disposed opposite to the first end wall 167a. The first end wall 167a and the second end wall 167b are connected to the primary cavity 120, the main wall 164 at each of the first, second, and third portions 164a, 164b, 164c, and the edge wall 166. The first and second end walls 167a, 167b, the main wall 164, and the edge wall 166 form the secondary cavity 160. Furthermore, the first and second end walls 167a, 167b, the main wall 164, and the edge wall 166 partially define the secondary compartment 162 (shown in FIG. IB).

FIG. 4A shows an enlarged schematic side perspective view of a portion of the storage case 100, and FIG. 4B shows an enlarged schematic rear view of a portion of the storage case 100. The primary cover 140 is in the closed cover position 140b in FIGS. 4A and 4B. Further, the secondary cover 180 is in the closed cover position 180b in FIG. 4A. The secondary cover 180 and the secondary hinge joint 165 are not shown in FIG. 4B. The primary cavity 120 illustrated in FIGS. 4 A and 4B defines an opening 128 communicating with the secondary compartment 162. Specifically, the opening 128 illustrated in FIGS. 4A and 4B is defined on the second side wall 126b of the primary cavity 120. The secondary hinge joint 165 is at least partially disposed in the opening 128. As discussed above, the primary cover 140 is movably coupled to the primary cavity 120 at the first side wall 126a and the secondary cover 180 is movably coupled to the secondary cavity 160 at the edge wall 166 proximal to the second side wall 126b. Therefore, the opening 128 may allow the secondary cover 180 to move to the open cover position 180a (shown in FIG. 3B), while the primary cover 140 is in the closed cover position 140b. The opening 128 may be a cutout in the second side wall 126b that allows the secondary cover 180 to be movably coupled to the edge wall 166 and freely move between the open cover position 180a and the closed cover position 180b without any interference from the primary cover 140. In other words, the primary cover 140 and the secondary cover 180 may be movable independently of each other. Thus, the user may access the primary compartment 122 (shown in FIGS. 3A and 3B) or the secondary compartment 162 independently of each other, as desired.

Moreover, the pair of second protrusions 169b is disposed on the second end wall 167b and extends into the secondary compartment 162. The pair of first protrusions 169a and the pair of second protrusions 169b may aid in removably securing the power source within the secondary compartment 162. Moreover, the third portion 164c of the main wall 164 being curved may facilitate positioning and removable securement of the power source within the secondary compartment 162.

As illustrated in FIG. 5B, the storage case 100 further comprises a secondary latch mechanism 190 configured to releasably secure the secondary cover 180 to the secondary cavity 160. In other words, the secondary latch mechanism 190 may releasably secure the secondary cover 180 to the secondary cavity 160 in the closed cover position 180b (shown in FIG. 4 A). The secondary latch mechanism 190 may be of any suitable type, such as a clasp, a snap-fit latch, and the like. Specifically, the secondary latch mechanism 190 illustrated in FIG. 5B comprises one or more slots 172 and one or more extensions 182. The secondary cavity 160 defines the one or more slots 172 on the first portion 164a of the main wall 164.

In the closed cover position 180b (shown in FIG. 4A), the shoulder 184 may abut the engaging surface 170 such that the secondary cover 180 is disposed adjacent to the back wall 127. Moreover, the shoulder 184 and the engaging surface 170 may allow the secondary cover 180 to be flush with the back wall 127 in the closed cover position 180b. The storage case 100 further comprises a recess 130 extending from the back wall 127 to the engaging surface 170 in order to enable the user to move the secondary cover 180 from the closed cover position 180b to the open cover position 180a. Specifically, the recess 130 may allow the user to grip the shoulder 184 by a finger or fingernail to pry the secondary cover 180 from the closed cover position 180b to the open cover position 180a. FIG. 6A shows an enlarged schematic front perspective view of a portion of the storage case 100 and FIG. 6B shows an enlarged schematic side perspective view of a portion of the storage case 100.

The storage case 100 illustrated in FIGS. 6 A and 6B further comprises a primary latch mechanism 195 configured to releasably secure the primary cover 140 to the primary cavity 120. In other words, the primary latch mechanism 195 may releasably secure the primary cover 140 to the primary cavity 120 in the closed cover position 140b (shown in FIG. 2A). The primary latch mechanism 195 may be of any suitable type, such as a clasp, a snap-fit latch, and the like. Specifically, the primary latch mechanism 195 illustrated in FIGS. 6A and 6B comprises a resilient tab 192, an engaging protrusion 194, and a notch 196. The resilient tab 192 is movably connected to the primary cavity 120, specifically at the second side wall 126b of the primary cavity 120. Accordingly, the primary cover 140 illustrated in FIGS. 6 A and 6B defines a cutout 143 corresponding to the resilient tab 192 of the primary latch mechanism 195.

Further, the engaging protrusion 194 extends from the resilient tab 192. The notch 196 is defined on the primary cover 140 corresponding to the engaging protrusion 194. That is, in the closed cover position 140b (shown in FIG. 2 A), the engaging protrusion 194 is configured to be at least partially received in the notch 196 to releasably secure the primary cover 140 to the primary cavity 120. To move the primary cover 140 from the closed cover position 140b to the open cover position 140a, the user may press the resilient tab 192 to remove the engaging protrusion 194 from the notch 196. The primary latch mechanism 195 illustrated in FIGS. 6A and 6B is exemplary in nature and the primary latch mechanism 195 may include any suitable latch mechanism for releasably securing the primary cover 140 to the primary cavity 120.

FIGS. 7 A and 7B show a schematic top perspective view and a schematic bottom perspective view, respectively, of the storage case 100.

Further, the secondary compartment 162 has a maximum length extension L2 extending along a longitudinal axis 174 of the secondary compartment 162 and a maximum width extension W2 extending perpendicular to the longitudinal axis 174 of the secondary compartment 162.

The maximum length extension LI and the maximum width extension W1 of the primary compartment 122 may depend on the power-driven personal care implement to be stored in the primary compartment 122. Further, the maximum length extension L2 and the maximum width extension W2 of the secondary compartment 162 may depend on the power source to be stored in the secondary compartment 162. In some examples, the maximum length extension LI may be about 160 millimeters (mm) to about 170 mm. In some examples, the maximum length extension LI may be about 164 mm. Furthermore, in some examples, the maximum width extension W1 of the primary compartment 122 may be about from about 40 mm to about 50 mm. In some examples, the maximum width extension W1 of the primary compartment 122 may be about 45 mm.

In some examples, the maximum length extension LI of the primary compartment 122 is greater than the maximum length extension L2 of the secondary compartment 162 by a factor of at least two. In other words, in some examples, the maximum length extension LI is at least twice of the maximum length extension L2. Moreover, in some examples, the maximum width extension W1 of the primary compartment 122 is greater than the maximum width extension W2 of the secondary compartment 162 by a factor of at least two. In other words, in some examples, the maximum width extension W1 is at least twice of the maximum width extension W2.

Furthermore, in some examples, the storage case 100 is made from a material selected from the following list: polypropylene, polyethylene, ethylene-vinyl acetate, polyamide, acrylonitrile butadiene styrene, polyoxymethylene, acrylonitrile styrene acrylate, and any combinations thereof. Preferably, the storage case 100 is unitarily made from polypropylene. The materials recited in the list above may be suitable for molding and may be economically feasible. Furthermore, the materials recited in the list above may have desirable properties, such as., impermeability to water, moldability, non-toxicity etc., for making the storage case 100. Thus, in some examples, the primary cavity 120, the primary cover 140, the secondary cavity 160, and the secondary cover 180 are unitarily molded in one molding step. The primary cavity 120, the primary cover 140, the secondary cavity 160, and the secondary cover 180 may be unitarily molded by injection molding, blow molding, compression molding, transfer molding, or any other suitable molding process. Therefore, the storage case 100 may be easy and economical to manufacture, and may not require major modifications in existing manufacturing lines to manufacture. The storage case 100 may be made from recycled and/or recyclable and/or biodegradable material.

FIGS. 9 A and 9B show a schematic front perspective view and a schematic rear perspective view, respectively, of a personal care kit 200. The personal care kit 200 comprises the storage case 100. The primary compartment 122 is in the open position 122a and the primary cover 140 is in the open cover position 140a in FIGS. 9A and 9B. Further, the secondary compartment 162 is in the open position 162a and the secondary cover 180 is in the open cover position 180a in FIGS. 9 A and 9B.

The personal care kit 200 further comprises a power-driven personal care implement 210. The power-driven personal care implement 210 is removably stored in the primary compartment 122. The personal care kit 200 further comprises a power source 230 removably stored within the secondary compartment 162.

The power-driven personal care implement 210 may be any implement that requires power to operate, such as a power-driven oral care implement, e.g. a toothbrush, a power-driven razor, a power-driven epilator, and the like. The power-driven personal care implement 210 may receive power from any suitable power source, such as the power source 230. In other words, the power source 230 may be configured to be electrically connected to the power-driven personal care implement 210 for supplying power to the power-driven personal care implement 210 after being removed from the secondary compartment 162.

In some examples, the power-driven personal care implement 210 is a battery -driven implement. Accordingly, in some examples, the power source 230 is at least one battery 240. The at least one battery 240 may be any suitable battery, such as a double-A battery (AA), a triple-A battery (AAA), a 9-volt battery, a rechargeable battery, and the like. In some examples, the at least one battery 240 comprises a plurality of batteries 240.

The power-driven personal care implement 210 is preferably a power-driven oral care implement 220, and more preferably a power-driven toothbrush. Specifically, the power-driven oral care implement 220 illustrated in FIG. 9A is the power-driven toothbrush. The power-driven oral care implement 220 illustrated in FIG. 9A comprises a handle 222 and a head 224. The head 224 is repeatedly attachable to and detachable from the handle 222. However, in some other examples, the head 224 may be permanently connected to the handle 222. In some examples, the head 224 and the handle 222 may be integrally formed as a unitary component. The handle 222 may be grasped by the user during use of the power-driven oral care implement 220, and the head 224 comprises a plurality of filaments for providing oral care, such as brushing of teeth.

As illustrated in FIG. 9 A, the plurality of primary cavity retention features 121 removably secure and restrict movement of the power-driven personal care implement 210 when stored in the primary compartment 122. Specifically, the plurality of primary cavity retention features 121 removably secure and restrict movement of the handle 222 and the head 224 of the power-driven oral care implement 220, as illustrated in FIG. 9A. Moreover, the one or more retaining members 168 removably secure the power source 230 within the secondary compartment 162. Specifically, the one or more retaining members 168 removably secure the at least one battery 240 within the secondary compartment 162, as illustrated in FIG. 9B.

FIGS. 10A and 10B show a schematic front perspective view and a schematic rear perspective view, respectively, of the personal care kit 200. The primary compartment 122 is in the closed position 122b in FIGS. 10A and 10B. The primary cover 140 is in the closed cover position 140b in FIGS. 10A and 10B. Further, the secondary compartment 162 is in the closed position 162b. The secondary cover 180 is in the closed cover position 180b in FIGS. 10A and 10B. Some hidden parts of the storage case 100 are shown by dashed lines for illustrative purposes. Further, the power-driven personal care implement 210 and the power source 230 are shown by dashed lines.

In some examples, the primary cavity 120 and the primary cover 140 define a maximum thickness of the storage case 100 in the closed cover position 140b. In one example, the maximum thickness of the storage case 100 may be about 26 mm. Furthermore, in some examples, the primary cavity 120 and the primary cover 140 may have respective maximum thicknesses of about 13 mm.

Moreover, the plurality of primary cover retention features 141 may complement the plurality of primary cavity retention features 121 in removable securement of the power-driven oral care implement 220 in the primary compartment 122 when the primary cover 140 is in the closed cover position 140b and the primary compartment 122 is in the closed position 122b. In some examples, the primary cover retention features 141 may help in removably securing the handle 222 within the primary compartment 122.

The storage case 100 may be used to store the power-driven personal care implement 210 and the power source 230. As such, the power source 230 may not have to be carried separately from the storage case 100. Therefore, the storage case 100 may be suitable for being carried by the user during travel.

The storage case 100 may be used to store the power-driven personal care implement 210 in the primary compartment 122 and the power source 230 in the secondary compartment 162. As discussed above, the secondary compartment 162 may be separated from the primary compartment 122 in a substantially watertight manner. Further, the secondary compartment 162 may be configured to store the power source 230 electrically unconnected to any electrical conductors. Consequently, the storage case 100 may electrically isolate the power source 230 from the power- driven personal care implement 210. Therefore, the power source 230 may not get discharged when stored in the storage case 100. Further, when stored in the secondary compartment 162, the power source 230 may not pose an electrical hazard due to potential contact with electrically conductive contaminants, such as water and toothpaste, that may be present in the primary compartment 122. Specifically, the secondary cavity 160 may prevent entry of such contaminants into the secondary compartment 162 from the primary compartment 122. Moreover, since the primary cover 140 and the secondary cover 180 are movably connected to the primary cavity 120 and the secondary cavity 160, respectively, at opposing sides (i.e., proximal to the first and second side walls 126a, 126b, respectively) of the storage case 100, and further open from front and back sides (i.e., from the front open side 123 and the back wall 127, respectively) of the storage case 100, any accidental entry of contaminants from the primary compartment 122 to the secondary compartment 162 may be prevented when the primary compartment 122 and the secondary compartment 162 are open at the same time.
