Title:
COMPRESSION SPRING AND DISCHARGE DEVICE FOR CONTAINER
Document Type and Number:
Japanese Patent JP2022102886
Kind Code:
A
Abstract:
To provide a compression spring for suppressing decrease in elastic force, and to provide a discharge device for a container for suppressing decrease in repulsive force of an operation part.SOLUTION: A compression spring 1 includes at least one unit structure 2, the unit structure 2 has two annular members 6 that are separated each other in an axial direction along a center axis O and form an annular shape with the center axis O as a center each, and plural spring members 5 provided while shifting phases in a circumferential direction for circling the center axis O, the respective spring members 5 are extended linearly between two ends deviating in a circumferential direction between the two annular members 6 so as to connect them within a region positioned between the two annular members 6 along an axial direction, and respective ends of the respective spring members 5 are connected with the annular members 6 at a second angle larger than a first angle when it is assumed that the spring members 5 were extended spirally between ends when viewed in a radial direction along a straight line orthogonal to the center axis O.SELECTED DRAWING: Figure 1
