DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid locking and unlocking mechanism using a push button in a compact container.

[0002]

2. Description of the Related Art Conventionally, a hook is suspended from a front end portion of a lid rotatably hinged at a rear end portion of a container body, and a push button having a hook engaged with the hook can be moved in the front-rear direction. A compact container equipped with a locking / unlocking mechanism for a lid which is mounted by being urged forward by a spring in the front portion of the container body and opened by pressing a push button is known, and can be opened and closed with one touch. It is frequently used because it is easy to use. Also, various lid locking / unlocking mechanisms have been proposed for various types of compact containers.

[0003] Push buttons with hooks used in this type of compact container include a push button which is urged forward by a separately provided metal spring and a push button which is integrally formed with a spring. In terms of the price of the push button and the ease of assembly, an integrally molded product of the push button and the spring is superior. Also,
The weak point that the spring portion of the latter push button is easily plastically deformed is being overcome by the progress of synthetic resin materials.

A push button and a spring formed integrally are, for example, curved at the rear end of a push button having an upright hook, such as the push button shown in Japanese Utility Model Laid-Open No. 57-161907. The spring plate portion is provided on both sides of a push button with an upright hook, such as the one in which a spring plate portion is integrally protruded or the push button shown in Japanese Utility Model Application Laid-Open No. 61-96808. There is something.

[0005] These push buttons are arranged in the front part of the container body, and are housed so as to be unable to come out and to be movable in the front-rear direction by a middle frame covering the front part.

[0006]

However, the locking / unlocking mechanism of the lid using a push button of a type having a spring plate integrally protruded from the rear end thereof, is provided in the front-rear direction of the front portion of the container body. It has the drawback that the dead space becomes large and the effective space in which cosmetics can be stored becomes small, and it cannot be used for a container having a design with a small dimension in the front-rear direction.

Further, in the case of a locking and unlocking mechanism of a lid using a push button of a type in which a spring plate portion is integrally protruded on both sides, a housing space for the spring plate portion is provided on both sides of a front portion of the container body. Because of the necessity, the width of the front surface of the push button, which is the pressing portion of the push button, could not be widened, and the design and design constraints of the compact container were great.

The present invention has been made in view of the above problems, and uses a push button integrally formed with a spring to lock and unlock a lid with a small dead space in a container and a large degree of freedom in design. It is to constitute a mechanism.

[0009]

SUMMARY OF THE INVENTION According to the present invention, there is provided a main body having a concave portion at a front end portion, and an outer flange portion formed at an upper end of a storage peripheral wall to be mounted on the main body to constitute a main body storage portion. And a lid body having an engaging piece having an inward hook suspended from the distal end thereof and rotatably hinged at the rear end of the main body, and an outward hook portion engaging with the hook were formed. A push button having an engagement hole and being mounted in the recess of the main body so as to be movable in the front-rear direction, wherein a frame portion forming the engagement hole is provided on the back surface of the push button. A cantilevered spring plate portion is integrally provided outside the both side walls of the frame portion so as to protrude along the surface of the push button.

With the above configuration, the push button is
It is incorporated in the main body with the spring plate part settled on the back surface. Therefore, there is no dead space in the front portion of the main body, which is generated for accommodating the spring plate portion protruding from the push button as in the conventional example, and a large effective space for accommodating the cosmetic of the main body can be secured. .

[0011] Further, a notch recess having a width narrower than the width of the push button is provided on the front flange of the flange portion of the middle frame, the locking projection protruding outside both side walls of the push button. It is preferable to provide an engaging portion on the lower surface of both sides of the front flange on which the locking projections slide without being able to come out, and to incorporate the push button so as to fit and operate smoothly.
