Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a compact container, and more specifically, 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 lid, 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 inside the recess and a second engagement protrusion formed on the lid body. 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, a compact container of this type having a structure as shown in FIG. 5 is known. In this compact container, the push piece 1 is formed as a relatively hard piece of plastic, and the inner end of this plastic piece is formed with an inclined surface 2 that gradually descends from the top toward the lower rear. When the push piece 1 is pressed inward when the lid body 3 is in the closed position, the vertical force of the inclined surface 2 acts on the claw piece 4, causing the lid to close. A device in which the body 3 is pushed up and opened is known.

However, in this known compact container, the lid 3 is lowered from the inclined surface 2 of the push piece 1.
The force acting on the claw piece 4 is an oblique force perpendicular to the inclined surface 2, and this force is a horizontal force that presses the claw piece 4 of the lid body 3 against the inner surface of the recess 6 formed in the container body 5. It includes the component force of This horizontal component force strengthens the engagement between the first engaging protrusion 7 formed on the inner surface of the recess 6 and the second engaging protrusion 8 formed on the claw piece 4 of the lid body 3. Since it acts in the direction, opening the lid 3 involves a completely opposite effect, and a relatively strong force is required to open the lid by pressing the push piece 1 inward. That's what I did.

Also, the one shown in Fig. 6 is the push piece 1.
The lid body 3 is pushed up by an operating piece 9 extending from below the front pressing wall to the tip end face of the claw piece 4. When the push piece 1 is pressed inward by the actuating piece 9, the upper end surface of the actuating piece 9 comes into contact with the lower end surface of the claw piece 4 and pushes the claw piece 4 upward. At this time,
Due to the resistance caused by the engagement between the first engagement protrusion 7 and the second engagement protrusion 8, microscopically, the lower end of the actuating piece 9 is elastically bent at the joint with the front wall for pressing. A repulsive force is accumulated, and at the moment the second engaging protrusion 8 overcomes the first engaging protrusion 7, the repulsive force acts on the claw piece 4 of the lid body 3 all at once, opening the lid body. Become.

<Problems to be solved by the invention> In the conventional compact container shown in FIG. 6 above, since the repulsive force of the actuating piece 9 is utilized, the opening of the lid 3 is faster than in the compact container shown in FIG. Although it is possible to increase the angle, it is still not sufficient.

The present invention was developed in view of the above-mentioned problems, and its purpose is to improve the conventional compact container shown in Fig. 7, and to increase the repulsive force of the actuating piece so that the lid can be opened more widely. Our goal is to provide a compact container that can be used for any purpose.

<Means for Solving the Problems> In order to achieve the above object, according to the compact container of the present invention, the container body and the lid are hinged at their respective rear portions so that they can be opened and closed, and the front end of the container body is A recess is formed in the edge, and a first engagement protrusion is formed inside the recess, a second engagement protrusion is formed in the claw piece hanging from the edge of the lid, and the first In a compact container in which the lid body is held in a closed position by engagement between an engaging protrusion and a second engaging protrusion, a push piece made of synthetic resin is disposed in a recess so as to be movable in the front-back direction. However, the push piece has a cross-sectional "dog" shape, which is bent and extended from the bottom toward the front wall, folded back at the middle where it abuts the rear surface of the front wall, and further bent in the direction of abutting the rear end wall of the recess. The actuating piece is integrally formed, and a shelf portion for receiving the middle of the actuating piece is formed on the rear surface of the front wall.

<Embodiments> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the same reference numerals, including those used in the prior art described above, indicate the same or equivalent structural members.

Reference numeral 5 in the figure indicates a container body made of synthetic resin for storing cosmetics, etc., and a lid 3 is attached to the rear edge of the container body 5 via a pin 10 so that it can be opened and closed freely. It is worn. There is a mirror 1 on the inner surface of the lid body 3.
1 is glued thereto, and a claw piece 4 is integrally formed to hang down from its front edge. A recess 6 is formed in the front end of the container body 5 to correspond to the claw piece 4. A first engagement protrusion 7 is located above the inner depth of this recess 6.
is protruded, while the rear end of the hanging end of the claw piece 4 has a second
When the lid body 3 is closed, the claw piece 4 enters into the recess 6 of the container body 1, and the second engagement protrusion 8 formed on the claw piece 4 enters the recess 6. The first engaging protrusion 7 formed on the surface is crossed over and engaged, and the lid body 3 is in the closed position.

In the present invention, a push piece 1 made of synthetic resin is disposed in the recess 6, and as shown in FIG. front wall 1
side walls 13-13 extending rearward from both sides of 2;
A guide bottom plate 14 extending rearward from the lower end of the front wall 12
and an actuating piece 15 integrally connected to the guide bottom plate 14.
It is made up of. The rear end of the guide bottom plate 14 is provided with a locking piece 16 that projects downward in a hook shape for the purpose described later. The lower end 17 of the actuating piece 15 is bendably connected to the middle part of the guide bottom plate 14, and extends upward from there to connect the middle part 1 of the actuating piece 15.
8 is bent upward and toward the rear to form an arm portion 19.
is extending. The upper free end 20 of this arm portion 19 is formed into a forked shape, and the interval between the two forks is wider than the width of the first engaging protrusion 7 formed on the back surface of the recess 6. ing.

Further, a convex portion is integrally formed below the center of the rear surface of the front pressing wall 12, and the upper surface thereof is inclined rearward to form a shelf that receives the lower surface of the intermediate portion 18 of the actuating piece 15. It is designated as Section 21.

The push piece according to the present invention is made of an elastic resin, preferably polypropylene, polyoxymethylene, or polybutylene terephthalate.

In order to assemble the push piece 1 configured as described above into the recess 6 of the container body 5, the actuating piece 15 of the push piece 1 is bent from its lower end and middle portion 18 to have a substantially dogleg-shaped cross section. At the same time, the guide bottom plate 14 is pushed into the stepped guide hole 22 formed at the bottom of the inner surface of the recess 6, and the locking piece 16 of the guide bottom plate 14 is pressed.
is locked to the stepped portion of the guide hole 22 to prevent it from coming off.

When the lid 3 is closed against the container body 5 with the push piece 1 assembled in the recess 6 in this manner, the lower surface of the claw piece 4 of the lid 3 comes into contact with the upper end surface of the actuating piece 15. Press this down. Then, the arm portion 19 of the actuating piece 15 rotates downward about the intermediate portion 18 while bringing its free end 20 into contact with the inner surface of the recess 6, and the intermediate portion 18 of the actuating piece 15 rotates downwardly with its lower end 17, the intermediate portion 18 comes into contact with the rear surface of the pressing front wall 12 and presses the rear surface of the front wall 12 forward, and as a result, the push piece 1 engages the locking piece 16 of the guide bottom plate 14. is pushed forward to a position where it engages with the stepped portion of the guide hole 22. At this time, the intermediate portion 18 of the actuating piece 15 is brought into contact with the rear surface of the front wall 12, and its lower surface is received by the shelf portion 21. Thereafter, when the lid 3 is further pushed down, the bending portions at the intermediate portion 18 and the lower end 17 of the actuating piece 15 are elastically bent, and the second engagement protrusion 8 formed on the claw piece 4 of the lid 3 engages the container. Both are engaged by climbing over the first engaging protrusion 7 formed on the inner surface of the recess 6 of the main body 5, and the lid body occupies the closed position shown in FIGS. 1 and 2.

Since the push piece 1 of the present invention is made of synthetic resin and has elasticity at least at the bent portion, the downward stress applied to the upper end surface of the actuating piece 15 by the claw piece 4 in the above-mentioned closed position is
The force is transmitted in a direction that deeply deforms the intermediate portion 18 and the bent portion of the lower end 17 of the actuating piece 15, and a repulsive force is accumulated in these portions.

When you press your finger against the pressing front wall 12 of the push piece 1 from the locking position of the lid body 3 as described above and press it inward and rearward, the upper free end 20 of the actuating piece 15 is pushed into the inner surface of the recess 6. Since the arm portion 19 of the actuating piece 15 is in slidable contact with the front wall 1 in the initial stage,
2 pivots upward and forward on the shelf 21 on the rear surface of the container 2 with the intermediate portion 18 as a fulcrum, and a pressing force is applied to the claw piece 4 of the lid 3. At this time, the first
Since the engaging protrusion 7 and the second engaging protrusion 8 formed on the claw piece 4 of the lid body 3 are engaged with each other, this acts as a resistance and the actuating piece 15 is moved at two places, the middle part 18 and the lower end 17. It is elastically bent more deeply at the bending part, and elastic repulsive force is accumulated at these two places, so that when the second engagement protrusion 8 overcomes the first engagement protrusion 7, , the above-mentioned elastic repulsive force acts all at once, and the lid is opened wide.

In the above-mentioned preferred embodiment of the present invention, when the lid is closed, the claw piece of the lid presses the upper end surface of the actuating piece and bends the middle part and the lower end, so that the lid is in the closed state. Although residual stress is generated in these bent portions in the above, this is not an essential component of the present invention, and in the present invention, when the lid is opened, the residual stress is generated due to the engagement resistance between the lid and the container body. The elastic repulsion force is accumulated at the middle and lower bent portions of the pieces, and when the engagement between the two pieces is released, the repulsion force acts on the lid body all at once.

<Effects> As described above, in the compact container of the present invention, when the engagement between the first engagement protrusion formed on the container body and the second engagement protrusion formed on the claw piece of the lid body is released, Since the repulsive force accumulated in the bent portions at the middle and lower ends of the actuating piece acts on the lid body all at once, the opening angle of the lid body can be made larger than in the conventional case and the opening operability can be improved. . Furthermore, when the lid is closed, the intermediate bent part of the actuating piece of the push piece is on the shelf part of the pressing front wall, and in the initial stage of disengagement, the arm part rotates upward about the bent part on the shelf part. Since it moves, the claw piece of the lid body can be reliably raised.
