Title:
COMPRESSION SPRING AND DISCHARGE DEVICE FOR VESSEL
Document Type and Number:
Japanese Patent JP2022073357
Kind Code:
A
Abstract:
To provide a compression spring which is simple in a structure, hardly expanded in a radial direction at compression, and hardly wobbled, and a discharge device for a vessel using the compression spring.SOLUTION: A compression spring 1 includes at least one unit structure 2, and the unit structure 2 is composed of a pair of coil-shaped members 5 arranged around a center axial line while being shifted in a phase by an angle of 180°, and a pair of annular members 6 separating from each other in an axial direction along the center axial line, forming annular shapes with the center axial lines as centers, and making end parts 5a of a pair of the coil-shaped members 5 integrally continue to each other. A length of each of the coil-shaped members 5 from one end part 5a up to the other end part 5a exceeds a half round, and does not reach one round. A discharge device 10 for a vessel has the compression spring 1 and an operation part 12 for discharging contents of the vessel 11 by an operation for compressing the compression spring 1.SELECTED DRAWING: Figure 1
