Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device for a cosmetic compact.

Conventionally, most compact lid locks of this type are of the so-called latch type, in which an engaging protrusion protruding from the front edge of the lid engages with an engaging protrusion protruding from the front surface of the container body. However, in the case of this clasp type, the engagement protrusion is a very thin strip, and some design errors are unavoidable, making it difficult to achieve an appropriate degree of engagement. In some cases, this is even more difficult due to the addition of errors due to shrinkage during molding, and if the engagement is too strong, there is a risk of breakage.

The present invention aims to provide a cosmetic compact that is free from breakage and that can be locked well even if there is some error.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In each figure, 1 is a container body with a cosmetic filling chamber 2 recessed in the upper surface, and 3 is a hinge 4 at the rear of the container body 1.
5 is a locking piece that is attached to the front edge of the lid 3 and engages with the front surface of the container body 1 to lock the lid 3. Each part is molded from synthetic resin material. Manufactured.

The container body 1 has three surfaces, the front surface, the top surface, and the bottom surface, which are slightly concave on the front side of the central portion of the front wall 6, and storage grooves 7, 7 are formed from the top surface on both left and right sides of the concave portion. An engaging portion 8 is formed.

The lid 3 has a mirror 9 attached to the center of the back surface, a front edge center portion of the lower edge 10 corresponding to the container body engaging portion 8 cut off, and the storage space on both sides of the center portion of the back surface of the front edge portion. Bearings 11, 11 that enter the grooves 7, 7
is installed vertically.

The locking piece 5 is a gutter-shaped piece having a U-shaped cross section, and is arranged on the front central back surface of the lid 3 with both protruding pieces 12a and 12b facing upward and downward and inward.
Support shafts 13, 13 protruding from both left and right end surfaces of a
is pivotally supported by the bearings 11, 11 and is rotatably attached. In this case, the locking piece 5 is arranged with an appropriate gap 1 between it and the front edge of the lid 3. The lock piece 5 has an appropriate thickness so that the upper and lower protruding pieces 12a and 12b can be elastically deformed.

In the container body 1, it is preferable that the bottom concave portion of the engaging portion 8 be extended rearward to form the finger hook concave portion 14.

In the above configuration, when the lid is normally closed, the third
As shown in Figure 4, the lock piece 5 is the upper and lower protruding pieces 1.
2a and 12b are the block body 8a of the container body engaging portion 8.
The lid 3 is locked by being engaged with the lid 3 from the upper and lower surfaces. In this state, the outer surface of the base plate 12c of the lock piece 5 is flush with the outer surfaces of the container body 1 and the lid 3, as shown in FIGS. 1, 3, and 4.

To open the lid 3, put your finger on the corner A of the lower protruding piece 12b of the lock piece 5, bend and deform the upper and lower protruding pieces 12a and 12b of the lock piece 5 as shown by the broken line, and then open it forward. The lid 3 may be bent upward to disengage the container body engaging portion 8, and then open the lid 3 upward in this state. In this case, the operation becomes easy by placing the tip of the finger on the finger hook recess 14.

Next, when locking the lid 3, push the lower part of the locking piece 5 forward as shown in Figure 2, and then lock the lid 3.
Just push it downwards. Then, the upper protruding piece 12a of the locking piece 5 comes into contact with the upper surface of the block body 8a of the engaging part 8, and as a result, the lower protruding piece 12b turns over and engages with the bottom surface of the block body 8a, and locking is automatically performed. .

As described above, according to the present invention, the engaging portion 8 and the locking piece 5 are considerably larger in size than the conventional latch-type engaging protrusion, and the locking piece 5 can be elastically deformed, so it can be designed and molded. It is possible to provide a locking device that can absorb errors caused by shrinkage over time and is free from damage. Also, to unlock the lock, place the pad of your finger on the corner of the relatively wide lock piece 5.
It is easy to use and there is no risk of damaging fingertips or nails.
