Description

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

Generally, the body and the lid of a cosmetic compact are pivotally connected at the rear, and an engagement means is provided at the front to lock the closed lid.

The present invention is intended to enable such a cosmetic compact to be disengaged with a single push of a button, and is intended to be strong and less likely to break down.

The illustrated embodiment will be described below. 1 is
Flat body, 2 is a flat lid pivoted at the rear of the body, 4 is a movable push button on the front of the body, 5
is a support frame that prevents the push button from coming off.

The body 1 has a front wall 11 formed with a large depth, and a notch 1 in the center of the front wall that is open to the front and upper surfaces and has left and right edges 12a, 12a of the front surface protruding inward.
2, the inner bottom surface 12b of the notch is formed horizontally, and an engaging protrusion 13 is provided at the center thereof, and semicylindrical protrusions 14, 14 are provided protrudingly on the left and right sides, and both side wall surfaces 12c of the notch are provided. A relatively large recess 15 at the bottom of 12c,
15, step portions 16, 16 are provided on the upper part, and an engaging protrusion 17 is provided on the upper edge, and the upper end of the notch rear wall surface 12d is formed flush with the step portion 16.

The lid 2 has engaging protrusions 21 that correspond to the engaging protrusions 13 hanging from the lower front surface of the lid 2 so that they engage with each other when closed.

In addition, both the engaging protrusions 13 and 21 are provided with bending elasticity, and mutually engaging protrusions are provided at their respective tips.
At the time of engagement and disengagement, the engagement protrusion is caused to be overcome by elastic deformation.

The push button 4 is formed into a U-shape in plan view, with the outer surface of the intermediate side 41 serving as a pressing front surface 41a, which protrudes freely from the front opening of the notch 12, and has an upper surface and a lower surface formed horizontally. At the same time, the height is formed to be the same as the height of the notch 12, and both sides 42,
A semi-cylindrical recess 4 is provided at a suitable location on the lower surface 42a, 42a of 42.
3.
4, 14, and bar-shaped protrusions 44, 44 are provided protrudingly in the middle of the outer surfaces of both sides 42, 42, and the tips of the protrusions are cut out to form recesses 1 in both side wall surfaces 12c, 12c.
It is loosely fitted into 5 and 15.

The support frame 5 is formed into a U-shape in plan view, and the middle side 5
1 on the notch rear wall surface 12d, and both sides 5
2 and 52 are notched and the step part 1 of both side wall surfaces 12c and 12c is
6, 16, on the upper edge of the notch 12,
The upper surface is fitted flush with the upper surface of the body 1, and grooves 53, 53 are horizontally provided on the outer surfaces of both sides 52, 52, and the grooves are connected to the protrusions on the upper edges of both side surfaces 12c, 12c. The rod-shaped protrusions 44, 44 are fitted into the rods 17, 17, and the rod-shaped protrusions 44, 44 are covered above by both sides 52, 52. Note that the lower surfaces of both sides 52, 52 are connected to the kamaboko-shaped protrusion 14,
It is preferable to use an arcuate surface or an inclined surface related to the arcuate surface of No. 14, so that the rod-shaped protrusions 44, 44 can slide.

Each of the above-mentioned members is molded from synthetic resin.

With the above structure, when the lid 2 is closed, the engaging protrusions 13 and 21 of the body 1 and the lid 2 engage with each other, and the closed lid 2 is locked, so that the lid 2 cannot be opened. Sometimes, when the push button 4 is pressed, the push button 4 is pushed upward by the semicylindrical protrusions 14, 14.
Therefore, the lid 2 is pushed up and the engaging protrusions 13, 2
1 is disengaged, all that is left to do is to pull up the lid 2. To close the lid 2 again, press button 4.
All you have to do is pull it toward you and push down the lid 2, which will close and lock the lid back to its original state.

In addition, the rod-shaped protrusions 44, 44 of the push button 4 are loosely inserted into the recesses 15, 15 of the cutout side wall surfaces 12c, 12c, but this is mainly for temporary fixing of the push button during assembly; The stop is rod-shaped protrusion 4
4, 44 are the front left and right edges 12a, 12 of the notch 12.
This is done by receiving it between a and the support frame 5.

According to the present invention, the closed and locked lid 2 can be released extremely easily and easily by pressing the push button 4 with a single touch, and the push button 4 is equipped so that it can be pushed into the body 1, making it easy to push. Since the lid 2 is mounted so as to ride on the protrusions 14, 14 and push up, the mounting structure is simple and does not require high precision.Moreover, the mechanical strength can be increased, and it can be made of synthetic resin. It can be made without any problems, has fewer failures, and can be provided at low cost.

Furthermore, in this proposal, the push button 4 is provided with a notch 1 in the front part of the body 1.
2, and since the push button 4 is formed in a U-shape in plan view, the engaging protrusion 13 as a locking means on the body 1 side can be effectively attached to the inner bottom surface of the notch 12. Can be installed protrudingly. That is, the engaging protrusion 13 can be formed as long as possible without protruding from the upper surface of the body 1. Therefore, the engagement protrusion 13 does not protrude from the upper surface of the body 1 and the puff etc. gets caught during use, making it difficult to use.Furthermore, by forming the engagement protrusion 13 long to increase elastic deformation, ,
The influence of dimensional errors caused by shrinkage during molding of the synthetic resin of the body 1 and the lid 2 is also small, and the opening/closing operation is further facilitated by improving the ease of assembly.
