Description

[Detailed description of the invention] <<Industrial application>> The present invention relates to a compact container, and more specifically to a compact in which a container body and a lid are hinged at their rear ends so that they can be opened and closed. This invention relates to an improvement in the opening/closing mechanism of a lid of a container.

<Prior Art> Conventionally, this type of compact container has a push piece formed as a relatively hard piece of plastic, and an inclined surface that gradually descends from the top to the bottom rear at the inner end of the plastic piece. The inclined surface is brought into contact with the lower end of the claw piece hanging down from the front end of the lid body, and when this push piece is pressed inward when the lid body is in the closed position, the vertical component of the inclined surface acts on the claw piece, causing the lid to close. A device in which the body is pushed up and released is known.

<<Problem to be solved by the invention>> However, in such a known compact container, the force acting on the claw piece of the lid body from the inclined surface of the push piece is an oblique force perpendicular to the inclined surface. , the vertical component of this oblique force becomes the opening force of the lid. Therefore, the opening force will change depending on the inclination angle of the inclined surface, but since there are restrictions on the movement stroke of the push piece, the inclination angle will be relatively steep, and the horizontal force between the claw piece and the container body will be This acts to strengthen the engagement, and as a result, a relatively strong force is required to open the lid by pressing the push piece inward.

An example of such a push piece in which the sailor's force acts to strengthen the engagement between the claw piece and the container body when the push piece is pressed is disclosed in Japanese Utility Model Application Publication No. 60-44708.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a compact container that can reduce the operating force of the pressing portion of the push piece.

<Means for Solving the Problems> In order to achieve the above object, the compact container according to the present invention includes a container body and a lid hinged to the rear end of the container body so as to be openable and closable. A compact container comprising: a first recess formed on the upper surface of the front end of the container body and having a bottom surface with an inclined surface rising toward the rear; and a first recess formed hanging down on the lower surface of the front end of the lid a claw piece that can be inserted into the first recess when the lid is closed and whose lower end approaches or comes into contact with the inclined surface; and a claw piece that projects rearward from the front wall of the first recess. a first engagement protrusion formed thereon; and a first engagement protrusion formed protruding forward from the front surface of the claw piece and engaged with the first engagement protrusion when the lid body is closed to lock the closed state of the lid body. a second recess formed in the front end surface of the container body, the second recess and the first recess communicate with each other, and the first recess is inclined. a through hole having a bottom flush with the surface; a push piece disposed in the second recess and movable in the front-rear direction; The push piece extends through the hole into the first recess, and when the push piece is pushed rearward, moves rearward and upward along the slope of the through hole or the first recess to push the first and The present invention is characterized by comprising an operating arm that operates to release the engagement of the second engagement protrusion and open the lid.

<<Example>> A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 indicates a synthetic resin container body in which cosmetics are stored, and a lid 3 is hinged to the rear edge of the container body 1 via a pin 2 so as to be openable and closable. A mirror 4 is bonded to the inner surface of the lid 3, and a claw piece 5 is integrally formed to hang down from the front end thereof. A first recess 6 is formed on the upper surface of the front end of the container body 1 to correspond to the claw piece 5 and has a bottom portion 6a with an inclined surface that rises toward the rear. A first engagement protrusion 7 is provided on the upper front surface of the first recess 6 to protrude rearward, while a second engagement protrusion 8 protrudes forward on the front surface of the claw piece 5. When the lid 3 is closed, the claw piece 5 is inserted into the first recess 6 of the container body 1, and the lower end of the claw piece 5 approaches the inclined surface 6a, and the second engagement protrusion 8 passes over and engages with the first engagement protrusion 7 of the recess 6, and the closed state of the lid 3 is locked. Furthermore, a second recess 9 is formed in the front end surface of the container body 1,
The second recess 9 and the first recess 6 are communicated through a through hole 10. The bottom surface 11 of the through hole 10 is formed to be flush with the bottom surface 6a of the first recess 6, and the rear side thereof is sequentially inclined upward.

In the present invention, a push piece 12 is disposed within this second recess 9, and this push piece 12 is connected to a pressing front wall 13 formed approximately vertically and horizontally extending from the lower end of this front wall 13 toward the inner rear. A through hole 1 is formed from the upper part of the inner surface of the bottom wall 14 and the front wall 12 extending to
The actuating arm 16 is formed to extend substantially horizontally into the first recess 6 through 0, and the actuating arm 16 has a thin flexible portion 15 at its base end so as to be tiltable. Note that a hook-like projection 1 is provided on the lower surface of the rear end of the bottom wall 14.
7 are integrally protruded.

In order to assemble the push piece 12 configured as described above into the second recess 9 of the container main body 1, the bottom wall 14 of the push piece 12 is inserted into the stepped guide hole formed at the bottom of the inner surface of the second recess 9. Push it into 18. In this manner, once the hook-like protrusion 17 at the lower end of the bottom wall 14 is pushed over the lower step of the guide hole 18, the push piece 12 is assembled so as not to be pulled out from the guide hole 18. When the push piece 12 is assembled into the second recess 9 in this manner, the lower rear end of the operating arm 16 comes into contact with the bottom surface 6a of the first recess 6. Then, attach the lid body 3 to the container body 1.
In the closed state, as shown in FIG. 2a, the upper rear end of the operating arm 16 is in contact with the lower end of the claw piece 5 of the lid 3, and the upper rear end of the operating arm 16 and the claw The abutting surfaces with the lower ends of the pieces 5 are sloped surfaces whose rear portions are inclined diagonally downward.

Now, as shown in FIGS. 2a and 2b, from the closed state of the lid body 3,
3 and press it internally and rearward, the lower rear end of the actuating arm 16 slides on the bottom surface 6a of the first recess 6 and rises to the front flexible portion 15.
Tilt backwards and upwards around the center. During this tilting,
The upper rear end of the actuating arm 15 presses against the lower end of the claw piece 5 and presses it slightly backward from above, which is the direction to weaken the engagement, so the second engagement protrusion 8 formed on the claw piece 5 is The lid body 3 is relatively easily detached from the first engagement protrusion 7 formed on the front surface of the first recess 6, and the lid body 3 is unlocked and opened.

Moreover, what is shown in FIG. 3 is a second embodiment,
In this second embodiment, the actuating arm 16 is formed to extend diagonally rearward and upward from the front upper surface of the bottom wall 14 of the push piece 12 via the flexible portion 15, and is inserted into the first recess 6 through the through hole 10. When the push piece 12 is pushed internally backward, the actuating arm 1
6, its lower surface slides on the front edge of the bottom of the through hole 10, and the rear end of the actuating arm 16 tilts upward while pressing the claw piece 5 backward and upward to close the lid body 3.
It is designed to unlock and open the door.

Note that the present invention is not limited to the above embodiments,
For example, when the lid body 3 is closed, the lower end of the claw piece 5 may be in contact with the inclined surface 6a of the first recess 6, and the operating arm 16 may be close to the lower end of the claw piece 5. It may be hot.

<<Effect of the invention>> As described above, in the compact container according to the present invention, when the push piece is pressed backward, the actuating arm presses the claw piece of the lid body backward and upward, so that the second part formed on the front surface of the claw piece is The engagement between the engaging protrusion and the first engaging protrusion formed on the front wall of the first recess is weakened so that both can be easily separated, and the lid body can be unlocked and opened with a relatively light operating force. I can do it.
