Description

[Detailed description of the invention] <<Industrial application>> The present invention relates to a compact container, and more specifically, a compact container in which a container body and a lid are pivotally connected at their respective rear parts so as to be openable and closable. This invention relates to an improvement in the opening structure of a lid body.

<Prior Art> Conventionally, this type of compact container has a push piece disposed in a recess in the container body, and this push piece is formed as a relatively hard piece of plastic, and the inner end of the plastic piece is connected from the upper part to the lower rear part. An inclined surface is formed that gradually descends toward the front end of the lid, and this inclined surface comes into contact with the lower end of the claw piece hanging down from the front end of the lid, and when the push piece is pressed inward at the closed position of the lid, the slope There is a known device in which a force perpendicular to the surface acts on a claw piece to push up and open the lid.

However, in the case of compact containers using conventional push pieces, it is not possible to lengthen the pushing stroke of the push piece. The angle of the tapered surface must be made steep, and in such a case, it becomes difficult for the lower rear part of the tapered surface to fit under the claw piece provided on the lid, and the angle between the claw piece and the tapered surface is small. Therefore, the upward component of the force applied to the claw piece in response to the pressing force when pushing the push piece becomes small, resulting in problems such as being difficult to push and requiring a large force to open the lid.

<<Problems to be solved by the invention>> Therefore, in order to solve the above-mentioned problems in Utility Application No. 60-36095, the applicant of the present invention proposed a flexible part that is thinner than the lower rear position of the front wall for pressing. A push piece having an operating arm integrally extended upwardly at the rear thereof is disposed in a recess of the container body so as to be movable in the front and back direction, and the rear end of the operating arm is slidably abutted on the inner surface of the recess. , a compact container in which when the front wall of the push piece is pressed inward when the lid is in the closed position, the operating arm rises along the inner surface of the recess, touches the bottom surface of the lid and pushes it upward. proposed. Although this compact container has the advantage of improving operability because the actual stroke of the push piece can be made longer than conventional ones, it also has an engaging protrusion that protrudes from the inner surface of the recess that houses the push piece. As a result, the inner surface is not flush, and the operating arm of the push piece moves smoothly only up to the vicinity of the engaging protrusion, making it difficult to secure a sufficiently large stroke for thin compact containers, for example. , was not satisfactory.

<<Purpose of the invention>> The present invention was made in view of the above circumstances, and its purpose is to simplify the structure, ensure a sufficiently large stroke, and easily and reliably open the lid at a large angle with a small force. To provide a compact container equipped with an opening/closing mechanism capable of opening and closing the container.

<Means for Solving the Problems> In order to achieve the above object, the compact container of the present invention has a compact container in which the container main body and the lid body are pivotally connected at their respective rear portions so as to be openable and closable. , a first recess is formed in the front edge of either the container body or the lid;
A rear edge of the recess is extended to form a claw piece, a first engaging protrusion is formed on the rear surface of the claw piece, and a front part of either the lid body or the container body is provided with a first engaging protrusion. A second recess into which the claw piece can be inserted is formed, a second engaging protrusion is formed on the inner surface of the second recess, and the first engaging protrusion and the second engaging protrusion are connected to each other. The cover body is held in the closed position by engagement with the mating protrusion, and a push piece is disposed within the first recess so as to be movable in the front and back direction, and the push piece has a push piece attached to the rear of the front wall for pressing. The actuating arm is integrally extended diagonally rearward through a thin flexible portion, and the rear end of the actuating arm is brought into sharp contact with the inner surface of the first recess to move the push piece inside and rearward. When pressed, the rear end can vertically slide on the front surface of the claw piece from the inner surface, and in the closed position of the lid, it is close to the rear end edge of the actuating arm and under the lid. The end face or the upper end face of the container body is located there.

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

A lid 14 is hinged to the rear edge of the container body 10 via a pin 12 so as to be openable and closable. Lid body 1
A mirror 16 is glued to the inner surface of 4.

In the present invention, the first recess 18 is formed in the front end of the container body 10, and the upper edge of the inner surface defining the first recess 18 extends upward to form the claw piece 20.
are integrally formed. The back surface of the first recess 18 and the front surface of the claw piece 20 constitute a vertical wall 21 formed flush with each other, and the rear surface of the claw piece 20 is integrally provided with a first engagement protrusion 22. It is formed protrudingly. On the other hand, a second recess 24 into which the claw piece 20 can be inserted is formed in the front lower surface of the lid body 14 at a position opposite to the claw piece 20, and a lower end of the rear surface of this second recess 24 is formed. A second engagement protrusion 26 is integrally formed in the protrusion. Then, when the lid body 14 is closed, the claw piece 20 is inserted into the second recess 24 and the first engaging protrusion 22 provided on the claw piece 20 is inserted into the second recess 24. The second engagement protrusion 26 is crossed over and engaged, whereby the lid 12 assumes the closed position.

Furthermore, in the present invention, the first recess 18
A push piece 28 is disposed inside the push piece 28, and this push piece 28 has a front wall 30 for pressing that is formed substantially vertically, and a bottom wall 32 that extends horizontally from the lower end of the front wall 30 toward the rear of the interior. and an operating arm 36 extending diagonally rearward and upward from the front upper surface of the bottom wall 32 via a thin flexible section 34. The upper end surface (rear end edge) of the actuating arm 36 is a flat surface in the state shown in FIGS. 1 and 2, and the rear end is an acute corner. Note that a guide protrusion 38 is integrally provided on the lower surface of the bottom wall 32 .

In order to assemble the push piece 28 configured as described above into the first recess 18 of the container main body 10, the bottom wall 32 of the push piece 28 is drilled downwardly and toward the inner depth of the first recess 18. Push it into the provided guide hole 40. At this time, the guide protrusion 38 provided on the bottom wall 32 of the push piece 28 is placed in the first recess 1.
8 is inserted into a guide groove 42 formed on the bottom surface of the housing. In this way, the push piece 28 is
When assembled into the recess 18 of the actuating arm 36
The rear end contacts the back surface of the first recess 18 and forms an angle formed by connecting the flexible portion 34 and the rear end of the actuating arm 36 to the back surface of the first recess 18. is an acute angle. When the lid 14 is closed to the container body 10, as shown in FIG.
The lower surface of the front edge of the lid body 14 is close to or in contact with the upper end surface of the operating arm 36 .

Now, as shown in FIG. 2, from the closed state of the lid body 14, the front wall 3 for pressing the push piece 28
When you press your finger on 0 and press it internally backward, the rear end of the actuating arm 36 rises while sliding on the vertical wall 21, and tilts upward around the lower flexible part 34. . During this tilting, the operating arm 3
The upper end surface of 6 presses against the lower end surface of the lid 14 and urges it upward, that is, in the direction of disengaging the engagement protrusions 22 and 26, thereby pushing the lid 14 upward. The vertical wall 21 consists of the inner surface of the first recess 18 and the front surface of the claw piece 20 formed flush with the inner surface of the first recess 18, on which the rear end of the actuating arm 36 smoothly slides. Move. Therefore, since the movable distance of the rear end of the actuating arm 36 becomes longer, the actual stroke becomes longer, and the second engagement protrusion 26 is relatively easily disengaged from the first engagement protrusion 22, and the lid is closed. The body 14 is opened to a relatively large angle.

FIGS. 4a to 4c are perspective views showing modified examples of the push piece used in the compact container of the present invention.
That is, the push piece used in this invention is the fourth
As shown in Figure a, the front wall 3 for pressing the actuating arm 36a
It may be provided from the lower part of the rear surface of 0a via the flexible part 34a. In addition, as shown in FIG.

As shown in FIG. 3, an actuating arm 36c may be provided from the center of the rear surface of the front wall 30c for pressing via a flexible portion 34c.

Figure 5 shows the second compact container according to the present invention.
An example is shown. In this embodiment, unlike the first embodiment, a push piece 28 is disposed on the lid body 14.

That is, the first recess 1 is formed in the front edge of the lid 14.
8', the lower end edge of the inner surface of the first recess 18' extends downward, and a claw piece 20' is integrally formed to hang down. Coupling protrusion 2
2', a second recess 24' is formed on the upper surface of the front part of the container body 10, and a second engaging protrusion 24' that can be engaged with the first engaging protrusion 22' is provided at the upper end of the rear surface of the second recess 24'. A protrusion 26' is formed. Furthermore, the lid 1
The push piece 28 is inserted into the first recess 18' provided in the upper part 4 with the top and bottom upside down, that is, with the bottom wall 32 facing upward. In other words, the front end of the compact container in the first embodiment is turned upside down.

Also in this embodiment, in order to open the lid 14 from the closed position, the push piece 28 may be pushed rearward in the same manner as in the first embodiment. Then, contrary to the first embodiment, the rear end of the operating arm 36 of the push piece 28 descends from the inner surface of the first recess 18' while sliding on the front surface of the claw piece 20'.
It presses against the upper surface of the front edge of the container body 10 to urge the container body 10 downward. At this time, if only the lid 14 is gripped, the container body 10 will be
At the same time as the engagement of 26' is released, it rotates in the opening direction due to its own weight, and when the container body 10 is gripped, the reaction force of the downward biasing force of the operating arm 36 against the container body 10 The lid body 14 is urged in the opening direction, and the lid body 14 is opened.

In this embodiment, since the push piece 28 is disposed on the lid 14, the thickness of the lid 14 is thicker than that of the conventional one. Therefore, a recess 46 is formed in the center of the lower surface of the lid 14, and a It is also possible to store the puff 48 and the like.

Incidentally, other structures and functions are the same as those of the first embodiment, so explanations thereof will be omitted.

<<Effects>> As described above, in the compact container according to the present invention, when the push piece 28 is pushed internally rearward, the operating arm 36 moves while urging the lid body 14 in the direction of separating it from the container body 10. At this time, the open edges of the inner surfaces of the first recesses 18, 18' are extended to form claw pieces 20, 20', and the first engagement protrusions 22 are provided on the rear surfaces of the claw pieces 20, 20'. ，
22' allows the rear end of the actuating arm 36 of the push piece 28 to move smoothly from the inner surface to the front surface of the claw piece, thereby increasing the substantial stroke of the push piece. Therefore, the engagement projections provided on the container body 10 and the lid 14 can be reliably released with a small force, and the lid 14 can be opened to a relatively large opening angle. Operation becomes easier.
