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 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, the 10th compact container of this type
A structure as shown in the figure is known. The push piece 1 is formed as a relatively hard plastic piece, and the inner end of the plastic piece is formed with an inclined surface 2 that gradually descends from the top toward the lower rear, and this inclined surface 2 hangs down from the front end of the lid body 3. Nail piece 4
When the push piece 1 is pressed inward at the closed position of the lid 3, the vertical force of the inclined surface 2 acts on the claw piece 4 to push up the lid 3 and open it. It is now publicly 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.

In addition, in the one shown in FIG. 11, the lid 3 is pushed up by an operating piece 9 extending from below the front pressing wall of the push piece 1 to the tip end surface of the claw piece 4. Push piece 1 is operated by this actuating piece 9.
When pushing the pusher piece 1 inwardly, it is sufficient to lightly press the pusher piece 1 in order to efficiently apply vertical force to the claw piece 4 while the tip rotates outward around the base. . However, the lid body 3
The maximum opening angle of the 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 regulate the size of the container body as much as possible. There are restrictions from the request.

Furthermore, as shown in Japanese Utility Model Application Publication No. 56-45406, the actuating piece of the push piece is bent diagonally upward from the front of its bottom toward the inner surface of the recess formed in the front edge of the container body. There is a known compact container in which the container extends diagonally upward by being folded back at a position where it abuts the inner surface, and whose free end abuts the lower surface of the lid at a position forward of the engagement portion between the lid and the container body. It's summery.

[Problems to be solved by the invention] However, in this known compact container, the upper part of the actuating piece extends upward beyond the upper end of the pressing front wall of the push piece. When the pressing front wall of the push piece is pressed inward, this pressing force is transmitted from the lower end of the actuating piece so that the actuating piece extends upward, so the actuating piece is formed from a thin piece. In such a case, the transmission of force is poor and the lid cannot be opened unless the actuating piece is pushed in far. In addition, after the lid is opened, the actuating piece protrudes from the push piece, causing the push piece to wobble in the recess of the container body, and when the lid is closed again after opening, the upper end of the actuating piece is Not only is there a risk that the lid will not fit in the designated position on the bottom of the body, but it will also look unsightly after the lid is opened.

The present invention was developed in view of the above-mentioned problems, and its purpose is to bring the free end of the actuating piece into contact with the inner surface of the pressing front wall of the push piece.
The inward pressing force applied to the front pressing wall acts directly not only on the lower end of the actuating piece but also on the upper end, making it possible to open the lid with a small pressing force and when opening the lid. The push piece returns to its original position due to the elastic restoring force of the actuating piece and does not wobble within the recess of the container body, which not only looks good but also prevents the actuating piece from blocking the lid. Provides a compact container.

<Means for Solving the Problems> In order to achieve the above object, in the present invention, the container body and the lid are hinged at their rear parts so that they can be opened and closed, and a recess is formed in the front edge of the container body. A first engagement protrusion is formed on the inner surface of the recess, and a second engagement protrusion is formed on a tab hanging from the front edge of the lid.
an engaging protrusion formed between the first engaging protrusion and the second engaging protrusion.
In a compact container in which the lid body is held in a closed position by engagement of an engagement protrusion, a push piece is disposed in the recess so as to be movable in the front and back direction, and the push piece has a front end for pressing. An operation that extends diagonally upward from the lower part of the wall or the front part of the bottom plate toward the back surface, turns back at the position where it abuts the back surface, and further extends diagonally upward toward the front pressing wall. The piece is integrally formed from a resin having plasticity and restorability, and the front surface of the free end of the actuating piece is attached to the inner surface of the pressing front wall, and the upper surface of the free end is attached to the lower end of the claw piece of the lid body. They are made so that they are in contact with each other.

《Operation》 When the push piece is pressed inward from the locking position of the lid, the pressing force is directly transmitted to the lower and upper ends of the actuating piece through the front wall, and the bent part in the middle of the actuating piece is pushed into the recess. The actuating piece is pressed against the back surface, and as a result, the actuating piece is crushed between the pressing front wall and the back surface and extends upward, pushing up the claw piece of the lid and opening the lid. When the pressing force is removed at this pressing position, the push piece returns to its original state due to the restoring force of the actuating piece. Even when the lid is opened, the upper end of the actuating piece is located below the upper end of the pressing 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 provided protrudingly, and on the other hand, 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, the push piece 1 is disposed within the recess 6, and the push piece 1 includes a pressing front wall 12 formed vertically and side walls 13 extending rearward from both sides of the front wall 12. 13
and a guide bottom plate 14 whose central portion extends rearward in a convex shape.
and an actuating piece 15 which is integrally formed with the lower end of the pressing front wall 12 and extends upwardly from there. Said guide bottom plate 14
The rear end edge is provided with a locking piece 16 formed to protrude downward into a hook shape, and this guide bottom plate 14 is provided with a guide provided at the lower part of the rear end wall 17 of the recess 6 of the container body 5, as will be described later. It is slidably inserted into the opening 17a. Further, the inverted dogleg-shaped actuating piece 15 has an intermediate bent portion 18 and a connecting portion 19 with the pressing front wall 12 that are bendable. If the angle of the bent portion 18 is widened within the range of plasticity of the material of the push piece 1, the free end portion 20 of the actuating piece 15 will move upward and then return to its original position. The push piece of the present invention uses a resin having this plasticity and restorability. Therefore, synthetic resin materials such as propylene, high-density polyethylene, polybutylene tereftate, polyoxymethylene, and polyethylene tereftate are desirable. still,
The push piece 1 is preferably molded in the shape shown in FIG.

In order to assemble the push piece 1 configured as described above into the recess 6 of the container body 5, the intermediate bent portion 1 of the inverted dogleg-shaped actuating piece 15 of the push piece 1 is
8 lightly abuts the rear end wall of the recess 6.
The push piece shown in the figure is bent at the middle and lower parts, and the guide bottom plate 14 formed on the push piece 1 is inserted backward along the floor of the recess 6, and further inserted into the guide opening 17a. The stopper piece 16 is locked to the bottom of the container body 5 to prevent it from coming off.

In this way, when the push piece 1 is assembled into the recess 6 and the lid 3 is closed to the container body 5 as shown in FIG. Free end face 20 of piece 15
is in contact with.

Now, when the lid body 3 is closed as shown in FIG. 4, when you press your finger against the pressing front wall 12 of the push piece 1 and press it inwardly, the lower end of the actuating piece 15 Since it is connected to the front wall 12, it is elongated at its intermediate bent portion 18 and its joining portion 19 with the front wall 12, and the free end 20 rises (FIG. 5). As a result, the free end 20 of the actuating piece 15 moves vertically to the lower end of the claw piece 4 of the lid body 3 and pushes it up, so that the second engaging protrusion 8 formed on the claw piece 4 is moved into the recess. The cover body 3 is relatively easily detached from the first engagement protrusion 7 formed on the inner surface of the cover body 6, and the cover body 3 is released.

The positions of the connecting portion 19 of the actuating piece 15 are as shown in FIGS.
You may choose any location, such as the front position.

<<Effects>> As described above, the push piece of the compact container according to the present invention has a push piece extending diagonally upward from the lower part of the front pressing wall or the front part of the bottom plate toward the inner surface of the recess formed in the container body. At the same time, an actuating piece is integrally formed from a resin having plasticity and restorability, and is folded back at a position where it abuts the back surface and further extends diagonally upward toward the front wall for pressing. Since the push piece is brought into contact with the inner surface of the front wall for pressing and the upper surface of the free end is brought into contact with the lower end of the claw piece of the lid body, when the push piece is pressed inward from the locking position of the lid body, the pressing force is The force is directly transmitted to the lower end and upper end of the actuating piece through the wall, and the bent portion at the middle of the actuating piece is pressed against the back surface of the recess, thereby causing the actuating piece to connect between the pressing front wall and the back surface. It is possible to open the lid by pushing up the claw piece of the lid with a small force. When the pressing force is removed at this pressing position, the push piece returns to its original state due to the restoring force of the actuating piece, so the push piece will not wobble within the recess of the container body when the lid is opened. Furthermore, even when the lid is opened, the upper end of the actuating piece is located below the upper end of the pressing front wall, so it looks good and does not become a hindrance when closing the lid.
