Description

[Detailed explanation of the idea] This case relates to a cosmetic compact.

The present invention is a cosmetic compact in which the body and the lid are pivotally connected at the rear and a lid locking means is provided at the front, and the front part of the body is equipped with a push button for releasing the lid locking means. The purpose is to make the lid opening operation easier, and to simplify the structure and provide it at low cost.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In the figure, 1 is a flat and rectangular body, and 2 is a lid corresponding to the body, which is flat and square in plan, and is pivoted to the rear part of the body. Reference numeral 3 denotes a push button for releasing the closing lid locking means attached to the front part of the body, and these are made by injection molding of a suitable synthetic resin.

The body 1 has a front side 111 of a peripheral wall 11 formed thick, a recess 12 opening forward or upward at the center of the front side, and a rear wall surface 1 inside the recess 12.
An engagement protrusion 13 is provided horizontally in the center of the upper part of the 21, and a recess 14 is provided in the lower part that extends further to the rear. Wall surface 12
A pair of left and right cam pieces 16, 16 are provided on the left and right side wall surfaces of the rear or recess 14 of 2,122, and both cam pieces have a pair of slants on the inner surface that gradually become narrower toward the rear and form a V-shape in plan view. Cam surfaces 161, 161 are formed.

The lid 2 is pivotally attached to the rear part of the body 1 at the rear part a, and has an engaging protrusion 21 hanging down that enters the recess 12 from the center of the lower surface of the front part and engages the engaging protrusion 13. This serves as a means for locking the lid.

The push button 3 is formed into a planar shape, is pushed into the recess 12, and is slidably installed inside the recess 12.
A pair of protrusions 32, 32 are provided protrudingly on the outer surface of 31,
The protrusions are slidably inserted into the guide grooves 15, 15, and the tips thereof are aligned with the inclined cam surface 16 on the inner surface of the front wall 33.
A pair of left and right elastic protrusions 34, 3 in contact with 1,161
4, and an elastic curved piece 35 is provided between both elastic protrusions, which is curved upward and whose middle portion faces directly below the engagement protrusion 21.

In the closed state of FIG. 4, the engaging protrusion 21 of the lid 2 engages with the engaging protrusion 13 of the body 1, as shown in FIG. 1, to lock the lid closed. has been done.

In this state, when the push button 3 is pushed backward, the pair of left and right elastic protrusions 34, 34 protruding backward
is guided by the inclined cam surfaces 161, 161 of the elastic protruding pieces 3 to elastically deform inward, and at the same time, the elastic curved pieces 3 between the elastic protrusions
5 is bent (elastically deformed) and its middle portion rises, and this rise pushes up the locking protrusion 21 and separates it from the engaging protrusion 13, as shown in FIG. After that, all you have to do is push open the lid 2 with your fingers.
This allows it to be opened without any restrictions.

Next, when the pressed push button 3 is released, the elastic curved piece 3
5 and the elastic protrusions 34, 34 are restored, the push button 3 automatically returns to its original state, and when the lid 2 is pressed down with a finger to close it, it returns to the closed lid locking state shown in FIGS. 1 and 4.

According to the present proposal, in the closed and locked state, the push button 3
When pushed in, the elastic material such as the elastic curved piece 35 on the push button is elastically deformed following the inclined cam surfaces 161, 161 of the body 1, and the engaging projection piece 21 of the lid 2 is pushed up by the elastic material. Therefore, the locking of the lid can be released extremely easily, and the lid can be opened extremely easily.

Further, the pressed push button 3 automatically returns to its original position by the restoring force of the elastic material such as the elastic curved piece 35, and therefore, the elastic material can be used for both purposes, simplifying the structure. By molding each member from synthetic resin, the number of members can be minimized, and furthermore, it is easy to manufacture and can be provided at low cost.
