Title:
DIRECT LIQUID PEN-TYPE EYELINER
Document Type and Number:
WIPO Patent Application WO/2024/075148
Kind Code:
A1
Abstract:
[Problem] To provide a direct liquid pen-type eyeliner that increases the feed rate of a liquid cosmetic P from a liquid cosmetic accommodation space to the pen tip, and does not cause the defect in which the liquid cosmetic leaks from the pen tip. A conventional outer capillary tube 42c has an insufficient capillary force, and therefore has the problem of being readily affected by a centrifugal G-force when the liquid cosmetic P contains a pearl pigment having a large particle diameter. [Solution] In this direct liquid pen-type eyeliner, a liquid cosmetic feeder 4 has a plastic core with a hybrid capillary tube in which an outer capillary tube 42c is formed on an outer peripheral side of the liquid cosmetic feeder 4 and an inner capillary tube 42b is formed on an inner peripheral side of the liquid cosmetic feeder 4. An annular cut portion is formed on a lateral face of the liquid cosmetic feeder 4 so that the liquid cosmetic P can be circulated to a pressure change buffer member via the annular cut portion.
