Description

[Detailed description of the invention] <Industrial field of application> The invention relates to a compact container, and more specifically, the container body and the lid are hinged at their rear parts so that they can be opened and closed. A recess is formed in the front edge, and a push piece is housed in this recess so as to be able to move back and forth, and a claw piece is formed hanging down on the front edge of the lid, so that when the lid is closed, this claw piece engages with the push piece. The present invention relates to a compact container in which the push piece and the claw piece are disengaged from each other when the push piece is engaged to occupy a closed position, and the push piece is pressed inward and rearward at the closed position.

<Prior Art> In a conventional compact container of this type, an inclined surface is formed on the inner surface of the pushpiece piece so that it gradually descends from the top toward the rear and the bottom, so that when the pushpiece is pressed inward and rearward from the closed position of the lid, the pushpiece At the same time as the engagement with the claw piece of the lid body is released, the inclined surface of the push piece pushes the claw piece upward, and even if the push piece returns to the forward position from the above-mentioned pressing position, it will not be able to engage with the claw piece again. There are well-known solutions that prevent this from happening.

However, since the slope of the inner surface of the push piece is used to push the claw upward, the opening angle of the lid is relatively small.

On the other hand, as shown in Utility Model Publication No. 57-7370, a resilient dog-shaped actuating arm is formed on the bottom of the push piece and extends upward, and the bent part of this actuating arm is attached to the front edge of the container body. When the push piece is pressed, the actuating arm bends and the tip of the actuating arm is brought into contact with the lower surface of the lid in front of the locking part between the lid and the container body, and the push piece is pressed. A compact container is provided in which the tip of the compact container pushes up the lid, and this compact container allows the lid to be opened at a larger angle by extending the operating arm of the push piece.

<Problems to be solved by the invention> However, in the above-mentioned compact container, when the push piece is pressed from the closed position of the lid, the arm above the bending part of the operating arm does not come into contact with the inner surface of the recess. As it rises while rotating backwards using the contact part as a fulcrum, the lid receives force from the operating arm rearward and upward, and this force strengthens the rearward force, that is, the engagement between the lid and the container body. Since the push piece has a component force in this direction, a relatively strong force is required to open the lid by pressing the push piece inward.

In addition, since the operating arm bent in a dogleg shape is bent to push up the lower surface of the lid, the upper part of the operating arm protrudes from the upper surface of the container body after the lid is opened, which obstructs the use of makeup. I had a problem with my sexuality.

Therefore, as in the compact container disclosed in Japanese Utility Model Application Publication No. 60-44708, an actuating arm extending horizontally is provided on the front wall of the push piece provided in a recess at the front end of the container body, and is activated when the push piece is pressed. A device is provided in which the rear end of the arm ascends an inclined surface formed in the recess, the actuating arm tilts upward, and the rear end pushes upward a claw piece formed to hang down from the lid body. ing.

In this known configuration, the lid is biased upward, and although no force is applied in the direction of strengthening the engagement, the force in the forward direction, that is, in the direction of releasing the engagement that separates the claw piece from the container body, is weak, and the lid is still opened. great strength is required.

The present invention was developed in view of the above-mentioned problems, and its purpose is to be able to smoothly disengage the lid even if the pressing force on the push piece is small, and to release the lid at a relatively large angle. To provide a compact container which is easy to use and has excellent usability in which the operating arm of a push piece does not protrude from the container body after the lid is opened.

<Means for Solving the Problems> In the present invention, when the lid is closed, the claw piece of the lid engages with the push piece to occupy the closed position, and when the push piece is pushed inward and rearward in the closed position, the push piece and the claw engage with each other. In a compact container configured such that the engagement with the piece is released,
An actuating arm is integrally formed on the push piece, extending from the lower position of the front wall for pressing to the rear upper part via the flexible part, and the rear end of the actuating arm is formed at an acute angle on the inner surface of the recess formed in the container body. When the push piece is pressed inwards and backwards, the rear end of the actuating arm slides on the back surface and can move upward, and when the lid is in the closed position, the upper end of the actuating arm is placed under the claw piece. It is characterized by being close to or in contact with the end face.

<Embodiments> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 indicates a container body made of synthetic resin, and a tray frame 2 for storing cosmetics is fitted into a recess on the upper surface of the container body 1.
The front end portion of the container body 1 extends beyond the recessed portion to the front end position of the container body 1. A lid 4 is hinged to the rear end edge of the container body 1 via a pin 3 so as to be openable and closable.
A mirror 5 is bonded to the inner surface of the lid 4. Lid body 4
A claw piece 6 is integrally formed to hang down from the front edge of the
A hook-like projection 7 is integrally formed on the lower inner surface of the claw piece 6. A window hole 8 is formed in the front edge of the tray frame 2 in correspondence with the claw piece 6, and a recess 9 is formed in the front edge of the container body 1, and the claw piece 6 closes the lid. When the plate frame 2 is opened, it can pass through the window hole 8 of the pan frame 2 and enter the recess 9.
The upper end of the rear surface of this recess 9 is bored inwardly, and there is a horizontal gap 1 between it and the lower surface of the front end of the tray frame 2.
0, and the inner surface of the lower part thereof is a vertical wall surface 11 with a smooth surface.

In the present invention, a push piece 12 is disposed within the recess 9, and this push piece 12 has a substantially vertical pressing front wall 1.
3, a ceiling plate part 14 extending horizontally rearward from the upper end of the front wall 13, a bottom plate part 15 extending slightly rearward from the lower end of the front wall 13, and a bottom plate part 15.
The actuating arm 17 extends diagonally backward and upward from the front upper surface of the actuator via a thin flexible portion 16. The ceiling plate portion 14 is slidably inserted into the gap 10 defined below the front end of the pan frame 2, and the push piece 12 is thereby movable in the recess 9 in the front-rear direction. There is. In addition, a through hole 18 is formed in this ceiling plate portion 14 and communicates vertically with a window hole 8 formed at the front edge of the pan frame 2.
An inclined image 19 is formed on the upper surface of the edge defining the rear end, and when the lid 4 is closed, the claw piece 6 of the lid 4 passes through the window hole 8 of the pan frame and hits the slope 19,
As a result, the lid body 4 is guided into the through hole 18 of the ceiling plate portion 14, and the hook-like protrusion 7 of the claw piece 6 engages with the rear lower edge of the through hole 18, so that the lid body 4 occupies the closed position. On the other hand, the rear end formed as an acute corner of the actuating arm 17 is in constant contact with the vertical wall surface 11 of the recess 6, and is formed by connecting this rear end, the flexible portion 16, and the vertical wall surface 11. The angles formed are acute. Then, the lid body 4 shown in FIGS. 1 and 2
In the closed position, the upper end surface of the operating arm 17 is substantially horizontal, and the lower end surface of the claw piece 6 of the lid body 4 is in contact with or close to the upper end surface.

Now, when the lid is closed as shown in FIG. 2, if you press your finger against the front wall 13 of the push piece 12 and press it inwardly, the entire push piece 12 will move inward, causing the lid to close. The hook-like protrusion 7 of the claw piece 6 of the body 4 disengages from the rear lower edge of the through hole 18, and the claw piece 6 comes to be located at the center of the through hole 18. At the same time, the rear end of the actuating arm 17 rises along the vertical wall surface 10 of the recess 9, so it tilts forward and upward about the lower flexible portion 16, and its upper end surface moves the claw piece 6 upward. push up to As a result, as shown in FIG. 3, the hook-like protrusion 7 of the claw piece 6 is located above the lower surface of the through hole 18, so that even if the push piece 12 returns to its forward position, the through hole again 18, and the lid is unlocked.

<Effects> As described above, in the compact container according to the present invention, when the push piece is pressed rearward inside, the operating arm slides on the inner surface of the recess and rises, and also moves forward and upward around the flexible part. Compared to a structure in which the claws of the lid are simply pushed up on an inclined surface, the amount of push-up of the claws can be increased, and the lid can be opened at a relatively large angle. be. In addition, as the operating arm pushes up the lid while rotating forward, the push piece separates from the claw piece, so there is a slight dimensional error in the molding of the engagement part between the push piece and the claw piece, and the engagement is not as specified. Even if the depth is deeper than in the case of , the claw piece will not get caught in the push piece, and no force will be applied to the lid body to strengthen the engagement, and the engagement can be smoothly released with a relatively small pressing force. .

Furthermore, the upper end surface of the actuating arm of the push piece acts on the lower end of the claw piece hanging down from the lid body to raise the claw piece, so that after the lid body is opened, the actuating arm of the push piece moves above the top surface of the container body. If it protrudes, the inconveniences caused by it will be eliminated and the usability will be excellent.
