Description

[Detailed description of the invention] <<Field of industrial application>> The present 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. The present invention relates to a compact container in which the lid body is closed by engagement with an engaging protrusion, 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 made to come into contact with the lower end of the claw piece hanging from the front end of the lid, and when the push piece is pressed inward at the stop position of the lid, the vertical force of the inclined surface acts on the claw piece. A device in which the lid is pushed up to open it is known.

Alternatively, as shown in Japanese Utility Model Application Publication No. 60-44708, an inclined surface rising at a constant angle toward the rear is formed on the inner protrusion of the container body, and the push piece has a rear surface of the front wall for pressing. An actuating piece is provided that extends horizontally from the center and has its rear end in contact with the inclined surface, and when the push piece is pressed backward, the actuating piece rises along the inclined surface, causing the lid body located directly above the actuating arm to move upward. A device in which the lid and the container body are unlocked by pushing up a claw piece is known.

<<Problems to be Solved by the Invention>> However, in these known compact containers, the inclined surface formed on the push piece or the container body is at a constant angle. The smaller this inclination angle is, the larger the vertical force acting on the claw piece of the lid body becomes, and the unlocking force becomes smaller.However, since the amount of rise of this claw piece is small, the opening angle of the lid body after the lid is unlocked is smaller. is small, and the operability of opening the lid by hooking the thumb on the front edge of the lid is poor. On the other hand, if you try to increase the opening angle of this lid body to improve the opening operability, the inclination angle will increase, and it will be necessary to apply a large pressing force (unlocking force) to the push piece. This results in poor operability.

The present invention was developed in view of the above-mentioned problems, and its purpose is to reduce the unlocking force of the lid with a small tilt angle when the lid is unlocked, but to reduce the unlocking force of the lid with a large tilt after unlocking. To provide a compact container which has excellent unlocking and opening operability and allows a lid to be opened at a large 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 is disposed in a recess formed in the front end of the container body so as to be movable in the front and back direction, and the push piece has an actuating piece that is inclined from the upper front to the lower rear with the upper front edge slidably abutting the rear surface of the front wall for pressing, and the lower rear edge of the actuating piece is recessed. The push piece is supported pivotably in the chamber, and when the lid is in the closed position, the upper surface of the actuating piece is brought close to the lower surface of the claw piece of the lid, and the push piece is moved rearward from the closed position of the lid. When pressed, the operating piece gradually rises using the rear lower edge as a fulcrum and pushes up the claw piece of the lid.

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

Figures 1A to 1D show the first embodiment of the present invention;
1 shows a container body made of synthetic resin, in which cosmetics and the like are stored. 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 bonded to the inner surface of the lid 3, and a claw piece 5 is integrally formed to hang down from the front edge of the mirror 4. A recess 6 is formed in the front end of the container body 1 to correspond to the claw piece 5. A first engagement protrusion 7 is provided on the upper rear surface of the recess 6, and a second engagement protrusion 8 is formed on the rear inner surface of the claw piece 5. As the piece 5 enters the recess of the container body 1, 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. will occupy the closed position. A guide hole 9 is formed at the bottom of the inner surface of the recess 6 toward the inner depth, and a guide recess 10 is formed at the bottom surface of the recess 6.

In the present invention, a push piece 15 is disposed within the recess 6, and this push piece 15 has a pressing front wall 16 formed substantially vertically.
, an upper protrusion 17 extending rearward from the upper end of the front wall 16 and having a substantially inverted U-shape in plan;
Bottom wall 18 extending horizontally from the bottom end to the rear
It consists of a pushup body, and a plate-shaped actuating piece 20 formed separately from the body. The bottom wall 18 is formed to be longer than the protrusion 17 so as to be inserted into the guide hole 9 of the recess 6, and is fitted on the lower surface of the bottom wall 18 with the guide recess 10 to support the push piece 15 slidably within the recess 6. A hook-like protrusion 19 is integrally provided. Plate-shaped actuating piece 2
0 is disposed between the front wall 16 of the push piece body mounted in the recess 6 and the inner surface of the recess, in an inclined state from the upper front to the lower rear.
The upper front edge 20a of the actuating piece 20 is in slidable contact with the rear surface of the front wall 16, while the lower rear edge 20b is formed by the lower end of the inner surface of the recess and the upper surface of the bottom wall 18. It is supported in contact with the corner.
When the lid 3 is closed to the container 1, the inclined upper surface of the actuating piece 20 is close to or in contact with the lower end surface of the claw piece 5 of the lid 3.

Now, when the lid body is closed as shown in FIG. Since it is in contact with the corner, it gradually rises while moving using this lower edge 20b as a fulcrum, and its front upper edge 20a
slides upward along the rear surface of the front wall 16. As a result, the upper surface of the actuating piece 20 comes into pressure contact with the lower end surface of the claw piece 5 and tries to push it upward, so that this pushing-up force causes the first engaging protrusion 7 to engage with the second engaging protrusion 7. When the projection 8 is disengaged and the lid 3 is unlocked, the lid 3 is opened to a considerable angle by the subsequent tilting of the operating piece 20. What should be noted here is that when the push piece 15 is initially pressed, the inclination angle θ of the actuating piece 20 is small, so while the component force in the horizontal direction is small, the component force pushing it up in the vertical direction is large. Although it does not require much force to release the engagement, once the engagement is released, the actuating piece 20 moves to the push piece 15.
The opening angle of the lid body 3 increases because it tilts freely as it moves.

FIGS. 2A to 2D show a second embodiment of the present invention, and the same parts as in FIGS. This embodiment differs from the first embodiment in that it is integrally formed including the operating piece 20'. That is, push piece 1 in this example
5' is integrally formed from resin with hinge properties, and its bottom wall 18' is cut out in the center.
A thin flexible piece 21 extends from the rear end 22 of this central notch.
is integrally extended rearward, and the rear end of the flexible piece is integrally connected to the central lower surface of the actuating piece 20'. The actuating piece 20' is arranged in a state in which the flexible piece 21 is curved upward, and its front upper edge 20'a is slidably in contact with the rear surface of the front wall 16'. , whose rear lower edge 20'b abuts and supports the corner formed by the inner surface and the bottom surface of the recess 6, and on both sides of the lower inner surface of the recess 6 are bottom walls 18'. A guide hole 9' is formed into which both sides of the guide hole 9' are inserted, and guide recesses 10' are formed on both sides of the bottom surface to fit with each hook-like protrusion 19'. The opening operation of the lid 3 in this second embodiment is the same as that in the first embodiment, so the explanation will be omitted.

In addition, in each of the above-mentioned embodiments, when the lock is unlocked, the actuating part 2
0 and 20' are arranged to act on the lower surface of the claw piece 5 of the lid body, but they may be made to act on other lower surfaces of the lid body 3.

<<Effect of the invention>> As described above, in the compact container according to the invention of the present application, when the front wall of the push piece is pressed inward and rearward, the actuating piece stands up while tilting upward around its rear lower edge, so that the lid body and the container body are When releasing the engagement with the lid, the inclination angle of the actuating piece is made relatively small so that the lock can be unlocked with a slight pressing force.After unlocking, the inclination angle of the actuating piece increases, so the opening angle of the lid body is set to be large. This allows for a compact container with excellent unlocking and opening operability.
