Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing structure for opening and closing the lid of a compact cosmetic container.

[Conventional technology]

A wide variety of opening/closing structures have been proposed in which the closed and locked lid can be opened by pressing a button.
A compact described in Japanese Utility Model Publication No. 56-25616 shown in Figures a and b is known.

In the case of this compact, a lid 2 is hinged to a container body 1 so that it can be opened freely, and the lid 2 is opened by operating an opening/closing mechanism. That is, the container body 1
A recess 3 is provided at the front end of the container, and a slide button 4 slides in the recess 3 in the longitudinal direction of the container. A locking portion 4a is provided at the front of the slide button 4 to protrude upward, and this locking portion 4a is brought into contact with the convex portion of the recess 3 to restrict the slide button 4 from retreating. It is designed to prevent it from coming off. Also, slide button 4
However, a slope 4b with a downward slope toward the front locking part 4a is formed at the rear. When the slide button 4 is pushed in and moved forward, the slope 4b comes into contact with the lower end of the front end wall of the lid body 2, and the lid The body 2 is lifted upward by the action of the inclined surface.

On the other hand, a locking protrusion 5 is provided on the front end surface of the opening of the recess 3 of the container body 1, and a locking protrusion 6 of the same shape is also provided on the lid body 2 at a position where the locking protrusion 5 faces the body. The lid body 2 is disengaged from the container body 1 by engaging and disengaging both the locking projections 5 and 6. That is, when the lid 2 is pushed down from the open state, the locking projection 6 engages with the locking projection 5 of the container body 1 in an undercut manner, and the lid 2 is closed. When opening the lid 2, push the slide button 4 forward and the lid 2 will open due to the action of the slope 4b as described above.
When pushed up, the locking protrusion 6 of the lid body 2 locks into the container body 1.
is forcibly removed from the locking protrusion 5.

[Problem that the invention attempts to solve]

However, in the case of the compact shown in FIG. 5, since the slide button 4 has a locking portion 4a and a slope 4b at the front and rear in the sliding direction, the container body 1 and lid body 2 that house it are However, it is necessary to allow for a longer breast dimension in the front-back direction. Therefore, there is a problem that the entire container becomes unnecessarily large in the front-rear direction.

The present invention was devised in view of the problems of the conventional example, and aims to provide an opening/closing structure for a compact container that can reduce the size of the entire container in accordance with the shape of the operation button.

[Means for solving problems]

In order to achieve this purpose, the opening/closing structure of the compact container according to the present invention has the following configuration.

That is, the lid body 20 is hinged to the container body 10 so as to be freely hinged, and the front end 11 of the container body 10
a guide groove 13 bored in the front and back direction of the container;
Recesses 14 that open upward from the inner edge 12 are provided at the inner part of the guide groove 13 in series.

In addition, a locking piece 22 is provided perpendicularly to the inner surface of the lid body 20 to protrude in and out of the recess 14 from above. A locking protrusion 23 and an inclined surface 24 having a downward slope toward the rear of the lid are formed adjacent to each other.

On the other hand, the slide button 30, which fits into the guide groove 13 and slides in the front-rear direction of the container, has a retaining portion 32 formed in the front portion thereof to restrict movement in the backward direction. An abutting step portion 34 is formed at the rear portion to restrict movement in the front-rear direction, and a stopper portion 34 is formed at the rear portion.
2 is the inclined surface 24 of the locking piece 22 on the lid body 20 side.
A contact piece portion 33 is formed that comes into contact with.

Here, the retaining part 32 of the slide button 30 is formed into a shape that is easily elastically deformed, and is formed into a shape that is easily elastically deformed.
It is assembled while being elastically deformed in the width direction of the guide groove 13 of No. 0, and is restored in the recess 14 so that it does not come out from the guide groove 13.

[Effect]

When closing and locking the lid 20, the lid 20 is pushed down to engage the locking protrusion 23 of the locking piece 22 with the inner edge 12 on the side of the container body 10.

When opening the lid 20 in the closed state, when the slide button 30 is pushed inside, the abutment piece 33 at the tip abuts against the inclined surface 24 of the locking piece 22. As the slide button 30 moves forward, a pushing force acts on the lid body 20, and this pushing force causes the locking protrusion 23 of the locking piece 22 to disengage from the inner edge 12 of the container body 10.

〔Example〕

Hereinafter, an embodiment of the compact container opening/closing structure according to the present invention will be described with reference to the drawings.

1 to 4, a lid 20 is hinged to the container body 10 at its rear end and can be opened freely. A guide groove 13 having a T-shaped cross section is bored in the front end 11 of the container body 10, and the back of this guide groove 13 becomes a recess 14 that opens upward at a distance from the inner edge 12 to the vertical wall 15. ing. Further, a cutout portion of the bottom plate 18 at the entrance of the guide groove 13 serves as an abutment step portion 17.

A tongue-shaped locking piece 22 is provided on the inner surface of the lid body 20 and projects vertically downward, and this locking piece 22 is inserted into the recess 1 provided on the container body 10 side when the lid body 20 is opened and closed.
4, it is located in a position where you can enter and exit from above. Further, a locking protrusion 23 is formed at the lower end of the locking piece 22 to engage and disengage from the inner edge 12 of the container body 10, and with the locking protrusion 23 in the center, both sides slope downward toward the rear of the lid. A sloped surface 24 is formed.

However, in this embodiment, the locking piece 22 has a shape in which sloped surfaces 24 are arranged on both sides of the locking projection 23, but the sloped surface 24 extends directly downward from the locking projection 23. You can.

On the other hand, as shown in FIG. 3, the slide button 30 that fits into the guide groove 13 and slides in the front and back direction of the container has a retaining part 32 on the front part thereof that restricts movement in the backward direction. It is formed. An abutment step part 34 is formed at the rear portion to restrict movement in the forward direction, and an abutment piece part 33 that abuts against the inclined surface 24 of the locking piece 22 on the lid body 20 side is adjacent to the retaining part 32. is formed.

Here, the retaining part 32 of the slide button 30 is formed with a slit between it and the adjacent piece part 33 so as to be easily elastically deformed.
It is assembled while being elastically deformed in the width direction of the guide groove 13 of No. 0, and is restored in the recess 14 to prevent it from coming out from the guide groove 13.

Next, the operation mode and effect of the embodiment will be explained.

When closing the lid 20 and locking it to the container body 10, push down the lid 20 and
As shown in FIG. 2, the locking protrusion 23 of the locking piece 22 is brought into engagement with the inner edge 12 on the container body 10 side.

On the other hand, when opening the lid body 20 from this closed state, when the slide button 30 is pushed inside, as shown in FIG. 2 and FIG.
comes into contact with the inclined surface 24 of the locking piece 22 on the lid body 20 side. When the slide button 30 moves forward, the abutting step 34 at the rear abuts against the abutting step 17 of the bottom plate 18 of the container main body, and further movement is prevented. At this blocking position, the abutting engagement between the abutment piece 33 and the inclined surface 24 of the locking piece 22 is released. As the slide button 30 moves forward, a pushing up force acts on the lid 20, and this pushing up force causes the locking protrusion 23 of the locking piece 22 to disengage from the inner edge 12 of the container body 10, causing the lid 20 to move forward. is unlocked and opened.

Therefore, as described above, the lid body 20 is
When closing the slide button 30, the slide button 30 is in a forward movement blocking position, and when the lid body 20 is pressed down, the inclined surface 24 of the locking piece 22 is pressed against the contact piece 33 at the tip of the slide button 30 in this blocking position. It will begin to engage, and due to the action of the slope, slide button 3 will now
Push 0 back in the backward direction. The slide button 30 is prevented from further retreating when the convex portion 32a of the retaining portion 32 comes into contact with the abutting stepped portion 16 on the container body 10 side. This inhibition causes the slide button 30 to return to the normal position shown in FIG.

During the backward movement of the slide button 30, the manner in which the locking protrusion 23 on the lid body 20 side engages with the inner edge 12 on the container body 10 side by dropping is as described above.

[Effect of idea]

As explained above, the compact opening/closing structure according to the present invention has, at the tip of the slide button, a piece part for releasing the engagement between the container body and the lid body, and a retaining part for regulating the slide back, which are adjacent to each other. Because of this, it is no longer necessary to allow for longer dimensions in the front-rear direction for the container body and the lid that house the slide button than in the conventional example.
Therefore, there is a practical effect that the entire container can be made smaller in the front-back direction.
