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, and the container body is 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 the closed position, a component force is generated to push up and open the lid body.

<Prior Art> Conventionally, as this type of compact container, one having a structure as shown in FIG. 4 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. The push piece 1 is brought into contact with the lower end of the claw piece 4 hanging down from the front end, and 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. A device in which the lid 3 is opened by pushing it up 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, what is shown in Fig. 5 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 pushed inward by the actuating piece 9, the tip of the push piece rotates outward about the base and efficiently applies a vertical force to the claw piece 4. 1
It is sufficient to press lightly. However, the maximum opening angle of the lid 3 is determined by the length of the actuating piece 9, and increasing the length of the actuating piece 9 means that the size of the recess 6 and the size of the push piece 1 will depend on the size of the container body. They are constrained by the demand for comprehensive regulation.

<Problems to be Solved by the Invention> According to the above-mentioned conventional technology, the role of the push piece is limited to releasing the engagement between the lid and the container body. Therefore, the invention of the present application was made in view of these problems, and its purpose is to be able to open the lid with a relatively small force when the push piece is pressed inward, and at the same time to open the lid as much as possible with a small mechanism. To provide a compact container with improved ease of use by increasing the opening angle to increase the separation distance between the container body and the lid.

<Means for Solving the Problems> In order to achieve the above-mentioned object, in the present invention, the container body and the lid are pivotally connected at their respective rear portions so as to be freely openable and closable, and a recess is formed in the front edge of the container body. At the same time, a first engagement protrusion is formed on the inner surface of the recess, a second engagement protrusion is formed on a claw piece hanging down from the front end of the lid body, and the first engagement protrusion and the second engagement protrusion are formed. In a compact container in which the lid body is held in a closed position by engagement of protrusions, a push piece made of synthetic resin is disposed in a recess so as to be movable in the front and back direction, and the push piece has a push piece attached from the rear surface of the front wall for pressing. A connecting piece extending rearward is formed so as to be freely bendable with respect to the rear surface of the front wall,
A pressing piece extending upward from the rear end of the connecting piece and an operating leg extending backward and downward are formed to be able to bend freely relative to the connecting piece, and when the lid body is in the closed position, the upper end of the pushing piece touches the inner surface of the recess. The lower end of the operating leg is in contact with the inner surface of the recess at the bottom of the push piece, and when the front wall is pressed backward, the distance between the rear surface of the front wall and the inner surface of the recess is reduced. At the same time, the upper end of the push-up piece and the lower end of the operating leg slide along the inner surface of the recess, and the angle between the push-up piece and the operating leg increases, and the rear end of the connecting piece rises to raise the push-up piece, causing the push-up piece to move upward. The end face raises the lid.

<Embodiments> Preferred embodiments of the present invention will be described below with reference to FIGS. 1 to 3 of the accompanying drawings. In addition,
The same reference numerals, including those used in the prior art described above, indicate the same or equivalent components.

Reference numeral 5 in the figure indicates a container body made of synthetic resin for storing cosmetics, etc., and a lid body 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 edge of the container body 5 to correspond to the claw piece 4. A first engagement protrusion 7 is formed in the upper part of the interior of this recess 6, while a second engagement protrusion 8 is formed at the rear end of the hanging end of the claw piece 4. As the claw piece 4 enters the recess 6 of the container body 1, the second engaging protrusion 8 formed on the claw piece 4 climbs over the first engaging protrusion 7 formed on the inner surface of the recess 6 and engages. Then, the lid body 3 assumes the closed position.

In the present invention, a push piece 1 made of a flexible material is disposed in the recess 6, and this push piece 1 has a vertically formed front wall 12 for pushing and a front wall for pushing 12 formed vertically. A guide bottom plate 13 extending rearward from the lower end of the wall, a connecting piece 14 formed extending rearward from the rear surface of the front wall 12, and a push-up piece 15 integrally formed at the rear end of the connecting piece 14.
and an operating leg 16. The front end of the connecting piece 14 , that is, the part where it connects to the rear surface of the front wall 12 is a first bent portion 17 , so that the connecting piece 14 can be bent toward the rear end of the front wall 12 . A push-up piece 15 is formed extending upward and rearward from the rear end of the connecting piece 14, and the operating leg 16 is connected to the connecting piece 14.
It is formed to extend downward and rearward from the rear end and the lower end of the push-up piece 15. Further, a second bent portion 18 is provided at the rear end portion of the connecting piece 14,
This allows the push-up piece 15 and the operating leg 16 to be bent with respect to the connection piece 14. and,
The upper end of the push-up piece 15 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 inner surface of the recess 6.

The rear end of the guide bottom plate 13 of the push piece 1 is provided with a locking piece 19 projecting downward in a hook shape for the purpose described later.

In order to assemble the push piece 1 configured as described above into the recess 6 of the container body 5, the guide bottom plate 13 is used.
A stepped guide hole 20 formed at the bottom of the inner surface of the recess 6
so that the locking piece 19 of the guide bottom plate 13 is locked to the stepped portion of the guide hole 20 and does not come off.

In this way, when the lid 3 is closed against the container body 5 with the push piece 1 attached to the recess 6, the lower surface of the claw piece 4 of the lid 3 comes into contact with the upper end surface of the push-up piece 15, and Pushing down, the push-up piece 15 rotates downward and rearward about the second bending part 18 while bringing its upper end into contact with the inner surface of the recess 6, and the operating leg 16 is pressed onto the guide bottom plate 13. The lower end comes into contact with the inner surface of the recess 6, and the angle α between the push-up piece 15 and the operating leg 16 becomes smaller. At the same time, the rear end of the connecting piece 14 moves downward and forward, and the angle β between the connecting piece 14 and the rear surface of the front wall 12 is approximately
90°, the connecting piece 14 pushes the rear surface of the front wall 12 forward, and the push piece 1 moves forward to the position where the locking piece 19 of the guide bottom plate 13 locks with the step of the guide hole 20. . At the same time, the second engagement protrusion 8 formed on the claw piece 4 engages the recess 6 of the container body 5.
The first engaging protrusion 7 formed on the inner surface of the first engaging projection 7 is crossed over and the two engage with each other to occupy the closed position as shown in FIGS. 1 and 2.

If you press your finger against the front surface of the push-up front wall 12 of the push piece from the closed position of the lid body 3 as described above and press it backward, the distance between the rear surface of the front wall 12 and the recess 6 will be shortened, and the recess 6 will be closed. The rear surface presses the upper end of the push-up piece 15 and the lower end of the operating leg 16 forward, and since the upper end of the push-up piece 15 is in contact with the back face of the recess 6, the push-up piece 15 is centered around the second bent part 18. The upper end slides upward on the back surface of the recess 6, and the upper end surface pushes the claw piece 4 upward. At the same time, the connecting piece 14 rotates upward and rearward about the first bent portion 17, and the angle β between the lower surface of the connecting piece 14 and the rear surface of the front wall 12 becomes 90 degrees or more, and the rear end of the connecting piece 14 rises. As a result, connecting piece 1
The actuating leg 16 integrally formed with 4 rotates upward and backward around its lower end,
The angle α between the push-up piece 15 and the operating leg 16 becomes larger than when the lid body 3 is closed. In addition, the connecting piece 14
The angle α increases by the amount that the rear end rises, and therefore the upper end of the push-up piece 15 is raised greatly, and the push-up piece 15
When the user pushes up the claw piece 4 and the second engagement protrusion 8 formed on the claw piece 4 overcomes the first engagement protrusion 7 of the recess 6, the lid body 3 is opened widely.

In addition, in the present invention, if the push piece is made of elastic synthetic resin, deformation repulsive force will remain in each bending part of the connecting piece, push-up piece, and operating leg of the push piece when the lid is closed, and the lid will When the engagement between the container body and the container body is released,
The repulsive force acts all at once, allowing the lid to flip up and open wide.

<Effects> As described above, in the compact container of the present invention, when the first engaging protrusion formed on the container body and the second engaging protrusion formed on the claw piece of the lid body are released, the push piece moves into the recess. Pressed forward towards the back,
At the rear end of the connecting piece of the push piece, the angle between the push-up piece and the actuating leg becomes large, and the push-up piece is raised by the connecting piece, so that the push piece can be pressed at least enough to disengage the lid and the container body. The opening operability is improved, and the opening angle of the lid is larger than in the conventional case.

Furthermore, the lid can be opened smoothly even if the dimensions of the first engaging protrusion formed on the container body and the second engaging protrusion formed on the claw piece of the lid vary and the engagement becomes stronger.
