Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a compact container.More specifically, the invention relates to a compact container, and more specifically, a container body and a lid are hinged at their respective rear portions so that they can be opened and closed. A recess is formed in the front edge of the recess, and a push piece is disposed within the recess so as to be movable in the front and back direction, and a first engagement protrusion formed on the inner surface of the recess and a second engagement protrusion formed on the lid body are provided. This relates to a compact container in which the lid body is closed by engagement with the engaging protrusion of the lid body, and when the push piece is pressed inward in this closed position, a component force is generated to push up and open the lid body. .

<Prior Art> Conventionally, in this type of compact container, the push piece is formed as a relatively hard piece of plastic, and the inner end of this plastic piece is formed with an inclined surface that gradually descends from the top to the bottom rear. 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.

However, in this known compact container, the force acting on the claw of the lid from the inclined surface of the push piece is an oblique force perpendicular to the inclined surface, and this force pushes the claw of the lid against the container body. This includes a component force in the horizontal direction that presses against the inner surface of the formed recess. This horizontal component force acts in the direction of strengthening the engagement between the first engaging protrusion formed on the inner surface of the recess and the second engaging protrusion formed on the claw piece of the lid body. Therefore, a relatively strong force was required to open the lid by pressing the push piece inward.

Therefore, as in the compact container shown in Japanese Utility Model Application Publication No. 60-44708, an actuating arm extending horizontally backward is provided on the front wall of the push piece provided in a recess at the front end of the container body, so that when the push piece is pressed, the actuating arm A device is provided in which the tip of the actuating arm rises up an inclined surface whose end is formed in the recess, and the actuating arm inclines upward to push up the claw piece hanging from the lid.

However, although the lid is urged upward by the operating arm, the force in the forward direction, that is, in the disengagement direction, is weak, and a large force is still required to open the lid.

<Problems to be solved by the invention> The present invention was made in view of the above-mentioned problems, and its purpose is to prevent the force applied to the push pieces when they are pressed inward from directly above and above the lid. To provide a compact container whose lid body can be opened with a relatively small force by lifting it up while being biased forward.

<Means for solving the problem> In order to achieve the above object, according to the compact container of the present invention, a push piece is disposed in a recess formed in the front end of the container body so as to be movable in the front and rear direction. The push piece has an actuating arm integrally extended rearward and upward from the inner surface of the lower part of the front pressing wall through a thin flexible part, and a claw member connected to the front wall so as to be movable in the front and rear directions. is provided at a rear position of the actuating arm, the lower surface of the actuating arm is slidably abutted on the claw member, at least one of the abutting portions of the actuating arm and the claw member is formed as an inclined surface, and the lid body is In the closed position, the upper end of the operating arm is located close to the lower surface of the lid.

<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 for storing cosmetics, etc., and a lid body 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 glued to the inner surface of the lid body 3,
Further, a claw piece 5 is integrally formed to hang down from the front end edge. A recess 6 is formed in the front end of the container body 1 to correspond to the claw piece 5. This recess 6
A first engaging protrusion 7 is provided protruding above the rear surface of the holder, and a second engaging protrusion 8 is formed on the rear inner surface of the claw piece 5. When the lid body 3 is closed, the claw piece 5 engages with the container. Main body 1
When the second engaging protrusion 8 formed on the claw piece 5 passes over the first engaging protrusion 7 formed on the inner surface of the recess 6 and engages with the lid, the lid body assumes a closed position. become. Guide holes 9-9 are formed on both sides of the bottom of the recess 6 toward the inner depth, and engagement grooves 10-10 are provided on both sides of the bottom of the recess 6.

In the present invention, a push piece 11 is disposed within the recess 6, and this push piece 11 is connected to a pressing front wall 12 formed approximately vertically.
, a bottom wall 13 - 13 extending horizontally rearward from both sides of the lower end of the front wall 12 , and an operation extending obliquely backward and upward from the center of the lower end of the front wall 12 via a thin flexible portion 14 . The arm 15 and the thin elastic piece 16- which curves in a substantially arc shape and protrudes from the inner surface of the bottom wall 13.
16, and a substantially L-shaped claw member 17, which are integrally formed by injection molding of synthetic resin. This claw member 17 is located at the rear of the operating arm 15, and the front end corner of the claw member 17 is located behind the operating arm 15.
The elastic piece 16 is in constant contact with the lower surface portion rising upward at the rear of the elastic piece 16, and is movable in the front-back direction relative to the front wall 12 by the bending of the elastic piece 16. Further, a hook-like projection 18 is provided on the lower surface of the bottom wall 13.
is installed protrudingly.

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 inserted into the guide hole 9 formed at the bottom of the inner surface of the recess 6, and the bottom wall A hook-like protrusion 18 formed on the lower surface of the recess 6 is fitted into the engagement groove 10 on the bottom surface of the recess 6 . In this way, push piece 1
1 is assembled into the recess 6, the rear end surface of the claw member 17 comes into contact with the inner surface of the recess 6. Furthermore, when the lid 3 is closed to the container body 1, the lower end surface of the claw piece 5 of the lid 3 is connected to the push piece 1.
It is close to the upper surface of the operating arm 15 of No. 1.

Now, when the lid body is closed as shown in FIG. 3, when you press your finger against the operating front wall 12 of the push piece 11 and apply an internal rearward pressing force to it, the front wall 12 becomes an elastic piece. The flexible part 14, which is a connecting part with the actuating arm 15, moves backward while bending the flexible part 16.
will move in the same way. As a result, the actuating arm 15 is guided by the front end corner of the claw member 17 and tilts forward and upward about the lower flexible portion 14 while rising. During this tilting, the upper end surface of the operating arm 15 is
In order to abut the lower end surface of the claw piece 5 and press it slightly forward from above, the second engagement protrusion 8 formed on the claw piece 5 engages with the first engagement protrusion formed on the inner surface of the recess 6. It is relatively easy to separate from the protrusion 7 and the lid is unlocked.

In the above-mentioned embodiment of the present invention, the lower surface of the operating arm 15 is made into an inclined surface, and this inclined surface is brought into contact with the front end corner of the claw member 17, and when the push piece 11 is pressed inward and rearward, the inclined surface and the corner are brought into contact with each other. Although the actuating arm 15 is made to rise through the section, conversely, a corner may be formed on the lower surface of the actuating arm 15, and an inclined surface may be formed on the claw member 17. Further, both of them may be formed as inclined surfaces.

Further, in the above embodiment, the actuating arm 15 acts on the lower surface of the claw piece 5 of the lid body when unlocking, but it may be made to act on other lower surfaces of the lid body 3.

<Effects> As described above, in the compact container according to the present invention, when the push piece 11 is pushed internally and rearward, the operating arm 15 slides on the claw member 17 and rises, and moves forward around the flexible part 14. Therefore, the lid 3 is lifted while being biased forward and upward in a direction that separates it from the inner surface of the recess of the container body 1, and the engagement between the lid and the container body is relatively weak. The cover can be easily removed by force, and the unlocking operation of the cover becomes easy.

Further, the claw member 17 of the push piece 11 is formed integrally with the front wall 12 via the thin curved elastic piece 16, and the rear end surface of the claw member 17 is brought into contact with the inner surface of the recess 6. A forward urging force always acts on the push piece 11, so that the push piece 11 does not wobble in the recess 6 when not in use, and when the pushing force on the push piece 11 is removed after the lid body 3 is opened. If the push piece automatically returns to its original position, the effect will be obtained.
