Description

[Detailed description of the invention] The present invention relates to the improvement of a compact container, and more specifically, to an opening/closing mechanism for a compact container in which the hinge part of the lid is connected to the rear end of the container body so that the lid can be opened and closed. It is about improvement.

In conventionally known compact containers of this type, hook-like protrusions are integrally formed on the front edges of the lid and the container body, and these protrusions are elastically engaged or disengaged. The lid is opened and closed, but in this case, it is necessary to form a recess for the finger on the outer surface of the container body or the lid in order to disengage the protrusion, which imposes design constraints. In addition, considerable dimensional accuracy is required to ensure smooth engagement and disengagement of the protrusions, resulting in disadvantages such as poor product yield.

Therefore, the applicant of the present application first attached a pressing piece near the protruding piece of the container body or the lid body, and the engagement of the protruding piece was released by the pressure of the pressing piece.
A compact container is provided that can tolerate dimensional errors in the protruding pieces to some extent. However, since the pressing piece is inserted into a long and narrow cavity, it may wobble during use, and the projecting piece or pressing piece is placed in a relatively conspicuous part of the compact container, so there are still design limitations. was unavoidable.

The present invention was developed by focusing on these conventional problems, and its purpose is to provide a compact container that can be configured with good appearance without being subject to design constraints, and is also extremely easy to use. It's about doing.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a container body, and a guide groove 2 extending in the front-back direction (left-right direction in FIG. 1) is formed on the inner bottom surface of the container body 1, and a recess is formed at the rear end of the container body. 3 is formed, and the recess 3 and the guide groove 2 communicate with each other via a notch 4 formed in the back wall of the recess, and the outer surface of the back wall adjacent to the notch 4 is relatively free. A small projection 5-5 is provided.

A slide member 6 is attached to the guide groove 2 so as to be slidable in the front and rear directions, and the front end of the slide member 6 forms a rising portion 7, and an engaging protrusion 8 is formed on the inner surface of the upper end. Further, the rear end of the slide member 6 extends from the notch 4 to the recess 3 to form an extension 9, and the rear end edge of the extension extends in the left-right direction (vertical direction in FIG. 2). The pressed end 10 is erected,
A protrusion 11 is formed at approximately the center of the front surface of the pressing end 10 so as to face forward. And protrusion 1
The center part of an elastic body 12 made of a plate spring is in contact with the tip of the elastic body 12, and this elastic body 12 extends in the left and right direction inside the recess 3, and the front surface near the center part is in contact with the recess 3.
The left and right ends 12a and 12b of the elastic body are formed to protrude rearward.

The tips of the left and right ends 12a, 12b are connected to the lid 13.
A pair of hinge pieces 14-1 hanging down from the rear end
4, respectively. The hinge piece 14-14 is inserted into the recess 3 of the container body 1 and connected to the rear end of the container body by a pin 15-15, and the pin hole of the hinge piece is inserted into the elastic body 12.
The hole is drilled below the contact area of the hole. A claw piece 16 is provided on the inner surface of the front end of the lid body 13, which is connected to the container body 1 by the hinge piece 14-14 so as to be openable and closable.
A hook-shaped engaged portion 17 is provided on the front surface of the lower end of the claw piece, and when this engaged portion 17 and the engaging protrusion 8 of the slide member 6 engage, the lid is opened. The body 13 is adapted to occupy a closed position.

An inner tray 18 containing cosmetics, etc. is attached above the slide member 6 inside the container body 1, and a hole 19 is bored in the center of the front edge of the inner tray to allow the lid 13 to engage. A joint 17 is freely accessible, and a mirror 20 is fixed to the inner surface of the lid 13.

In the closed position of the lid 13 shown in FIGS. 1 and 2 of the compact container described above, when the pressing end 10 of the slide member 6 is pressed and the slide member is slid forward, the engaging protrusion 8 moves forward and disengages from the engaged portion 17, and the protrusion 11 of the pressing end 10 presses the center of the leaf spring 12 forward, so that the inner wall of the recess 3 The leaf spring in contact with the protrusion 5-5 is bent in a dogleg shape around its center, and the left and right ends 12a, 12b are moved rearward from their original positions to the upper part of the hinge piece 14-14. Press backwards (see Figures 3 and 4). As a result, the hinge piece rotates clockwise around the pins 15-15, and the lid 13 is partially opened. From now on, the lid is opened at a desired angle to use cosmetics or the mirror 20. You can. Note that when the pressure on the slide member 6 is released, the slide member is returned to and held at a predetermined rear position by the biasing force generated in the plate spring 12, so that there is no wobbling or the like. In addition, after use, the lid 13
When closing, the elasticity of the leaf spring 12 is used to smoothly engage the engaged portion 17 with the engaging protrusion 8.

FIG. 5 shows another embodiment of the present invention, in which the end 1 of the extension 9 of the slide member 6 is
An elastic piece 21 is integrally formed in the left-right direction from the upper end of the distal end of the protrusion 11 formed at 0, and this elastic piece 2
1 to make it an elastic body. Then, when the pressing end 10 is pressed forward, the center part of the elastic piece 21 moves forward together with the slide member 6, and the elastic piece is bent in a dogleg shape, and the left and right ends 21a and 21b are attached to the hinge piece 14-14. The lid 13 is partially opened by pressing the upper part of the lid 13 backward. The other configurations and effects are the same as in the above-described embodiment.

As described above, in the compact container according to the present invention, the slide member disposed in the guide groove formed on the inner bottom surface of the container body is slid forward by pressing the rear end pressing end. At the same time as the engagement between the engagement part formed at the front end of the slide member and the engaged part provided on the inner surface of the lid is released, a gap between the rear end pressing end of the slide member and the back wall of the recess is released. By bending the provided elastic body and using the end of the elastic body to press the area above the pin of the lid hinge part backwards, the slide member can be easily pressed. It is convenient to be able to open the lid, and the opening/closing mechanism of the lid is no longer exposed directly to the outside surface, which improves the appearance and allows for various design improvements. It becomes possible to elaborate.

In addition, when the elastic body is a leaf spring that extends in the left-right direction centering on the slide member, the structure is simple and the operation is reliable. If it is made into pieces, the number of parts will be reduced and assembly will be easier.
