Description

[Detailed description of the invention] <<Field of industrial application>> The present invention relates to a compact container, and more specifically, the container body and the lid are hinged at their respective rear parts so that they can be opened and closed. A recess is formed in the front end edge, and a push piece is disposed within this recess so as to be movable in the front-rear direction, and an operating arm is integrally extended to this push piece via a thin flexible part, and The first engagement protrusion formed on the back surface and the second engagement protrusion formed on the lid body are engaged to close the lid body, and when this push piece is pressed inward, the lid body is pushed up and opened. The present invention relates to a compact container in which a component force is generated.

《Prior Art》 Conventionally, this type of compact container has an operating arm integrally extended rearward and upward through a thinner flexible portion than the lower position of the front wall for pressing of the push piece. The rear end is in contact with the inner surface of the recess in the container body, and its upper surface is in contact with the lower end surface of the claw piece hanging down from the front edge of the lid body, and when the lid body is in the closed state, this push piece is pushed back inside. There is a known device in which when pressed, the rear end of the actuating arm slides on the inner surface and pushes up the lower surface of the claw piece to open the lid.

<<Problems to be solved by the invention>> However, as shown in FIG. 7, when the overall thickness of the compact container is made thin, the operating arm 1
Since the inclination angle α of 5a with respect to the horizontal plane becomes smaller, the vertical force of the actuating arm pushing up the claw piece when pushing the push piece 11 horizontally becomes smaller, and a large pressing force is required on the push piece to open the lid. , the opening operability becomes poor. On the other hand, in order to improve the above-mentioned defect, it is conceivable to extend the operating arm 15a from the lower surface of the push piece as shown in FIG. 8 to increase the inclination angle β of the operating arm with respect to the horizontal plane. This makes it difficult to widen the opening angle of the lid by placing the thumb on the front end of the lid after opening the lid.

The invention of the present application was made in view of the above-mentioned problems, and its purpose is to be able to open the lid with a relatively small force even if the overall thickness of the compact container is made thin. To provide a compact container that can have a large opening angle.

<Means for Solving the Problems> In order to achieve the above object, according to the compact container of the present invention, a push piece movably disposed in the front and rear direction in a recess formed in the front edge of the container body The actuating arm is integrally extended rearward and upward from the intermediate position of the front pressing wall or a position below it through a thin flexible part, so that when the lid is closed, the rear end of the actuating arm is on the lower surface of the lid. and a claw piece hanging down from the front edge of the lid body, so that when the push piece is pushed inwards and backwards, the actuating arm rotates upward using the flexible part as a fulcrum and pushes up the lid body. It becomes like that.

<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a compact container made of synthetic resin.
A container body 1 in which cosmetics are stored and a lid 3 having a mirror 4 bonded to its inner surface are hinged at their respective rear portions via pins 2 so as to be openable and closable.

A recess 6 is formed at the front end of the container body 1, and a first engagement protrusion 7 is formed at the upper part of the inner surface of the recess 6. A claw piece 5 is integrally formed to hang down slightly behind the front edge of the lid body 3, and a second engagement protrusion 8 is formed on the rear inner surface thereof. When the lid body 3 is closed, the second engagement protrusion 8 formed on the claw piece 5 passes over the first engagement protrusion 7 formed on the inner surface of the recess 6 and engages with the lid body, and the lid body is in the closed position. will occupy . A stepped guide hole 9 is formed in the lower part of the inner surface of the recess 6 toward the inner depth, and a push piece 11 is disposed within the recess 6.

The push piece 11 is integrally formed with a vertical pressing front wall 12 and a bottom wall 13 that extends horizontally from its lower end toward the rear of the interior, and a hook-like projection 16 is integrally formed on the lower surface of the rear end of the bottom wall 13. It is set up protrudingly. An actuating arm 15 is integrally formed extending obliquely upward from the lower end of the front wall 12 of the push piece 11 via a flexible portion 14, and the vertical distance from the bottom wall 13 to the rear end of the actuating arm is The height is equal to or higher than the height of the wall 12, and the horizontal distance from the front wall 12 to the rear end of the operating arm is sufficiently shorter than the length of the bottom wall 13.

In order to assemble the push piece 11 configured as described above into the recess 6 of the container body 1, the bottom wall 13 thereof is pushed into the stepped guide hole 9 formed at the bottom of the inner surface of the recess 6. In this way, once the hook-like projection 16 at the lower end of the bottom wall 13 is pushed over the lower step of the guide hole 9, the push piece 11 is assembled so as not to be pulled out from the guide hole 9. In the closed state shown in FIG. 2 in which the lid 3 is closed with respect to the container body, the rear end of the operating arm 15 comes into contact with the corner 18 of the lower surface 17 of the lid and the claw piece 5. When the front wall 12 of the push piece 11 is pressed against the front wall 12 of the push piece 11 and pushed internally and rearward, the rear end of the actuating arm 15 comes into pressure contact with the corner 18, and the actuating arm 15 moves upward and downward using the flexible part 14 as a fulcrum. By rotating forward, the lid body 3 is pushed up and unlocked.

In the above embodiment, the flexible portion 14 of the actuating arm 15 extends from the lower position of the front wall 12 for pressing of the push piece, but as shown in FIG. It may also extend from the bottom wall 13 of the push piece in an intermediate position or as shown in FIG. In this case as well, the rear end of the actuating arm 15 is brought into contact with the corner 18 of the lower surface 17 of the lid body and the claw piece 5, and other configurations and operations are the same as in the first embodiment.

<<Effects>> As described above, in the compact container according to the present invention, the rear end of the operating arm of the push piece 11 comes into contact with the corner between the lower surface of the lid and the claw piece when the lid is closed. Even if the overall thickness of the compact container is made thin, the angle of the operating arm with respect to the horizontal plane can be made large, and the horizontal pressing force applied to the push piece is converted into a large vertical force that pushes up the lid body. The opening operability of the body is improved and the opening angle of the lid body can be increased.
