Description

[Detailed Description of the Invention] The present invention is characterized in that a lid is pivotally connected to the rear edge of the container body, which has a recess for storing cosmetics, etc., so that it can be opened and closed freely, and a claw part is provided on the edge of the lid. A first protruding piece is formed on the container body, and a second protruding piece is arranged on the edge of the container body, and the lid body is closed by engagement of the first protruding piece and the second protruding piece. The present invention relates to a compact container in which engagement between a first projecting piece and a second projecting piece is released by pressing inward a bushing piece provided at the edge of the container body.

In the above-mentioned type of compact container, the engagement between the lid and the container body can be released by simply pressing the bushing piece inward, which simplifies the opening of the lid.

However, since the opening angle of the lid when the bushing piece is pushed in is extremely small, when opening the lid to a desired angle, the thumb gets caught on the edge of the container body, making it somewhat difficult to open.

The present invention was developed in view of the above points, and its purpose is to release the closing engagement between the lid and the container body by pushing the bushing piece inward, and at the same time open the lid at a relatively large angle. The object of the present invention is to provide a compact container which has a simple structure and does not require additional parts such as springs.

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

In the first embodiment of the present invention shown in FIGS. 1 to 3,
Reference numeral 1 denotes a container body, in which a recess 2 for storing cosmetics and the like is formed.

A rear end hinge portion 4 of a lid body 3 is pivotally attached to the second container body 1 at its rear end portion by means of a bottle 5 so as to be movable together.

This hinge part 4 is integrally formed as a thick part perpendicular to the flat surface of the lid body 3, and a mirror 6 is attached to the inner surface of the lid body 3, and a claw piece 7 is integrally attached to the front edge of the hinge part 4. It is formed in a drooping manner.

A projecting piece 8 of the engagement brush 1 is formed on the inner surface of the claw piece 7, and a box-shaped recess 9 is formed by partially cutting out the front edge of the container body 1 corresponding to the claw piece 7. There is.

Inside this pock-shaped recess 9 is a push piece 10 with a U-shaped cross section. The first projecting piece 8 of the lid 3 is fitted into the bushing piece 10 so that it can move freely.
A second protruding piece 11 that can be engaged with 7 is integrally formed ffl.

This bushing piece 10 is always urged forward, that is, outwardly, by an elastic member such as a stripe link 12, and the lower surface protrusion 13 of the bushing piece 10
4 so that it does not disengage.

In the present invention, a rod-shaped protrusion 15 is integrally formed inside the rear end hinge part 4 of the lid 3 along the vertical direction, and when the lid 3 is closed, this protrusion 15 is inserted into the recess of the container body 1. The upper end of the rear wall 16 defining the rear surface of the rear wall 16 is pressed against the inner wall and elastically deformed.

The rear wall 16 is formed to be relatively thin so that its upper end is flexible to internal forces.

When the lid 3 of the compact container configured as described above is closed, the front claw piece 7 of the lid 3 enters the space of the bushing piece 10 having a U-shaped cross section, and the first protrusion 8 of the claw piece 7 is engaged with the second protrusion L1''1 of the bushing piece 10, and the lid body assumes the closed position as shown in FIG.

In this closed position, the protrusion 15 formed on the hinge 4 of the lid 3 forcibly presses the upper end of the rear wall 16 of the container body 1 inward, causing the rear wall 16 to move inward. It is slightly elastically curved.

When the bushing piece 10 is pushed inward from this closed position, the second protruding piece 11 integrated with this -5 moves inward and is disengaged from the first protruding piece 8. However, at the same time, the rear wall 16 of the container body 1, which had been elastically deformed, returns to its normal vertical state, so the lid 3 is flipped upward via the protrusion 15 of the lid hinge 4. Open.

FIG. 4 shows a second embodiment of the present invention, in which a pair of slits 17-17 are vertically formed in the rear wall 16 defining the recess 2 of the container body 1. When the flexible wall part 18 between the slits 17 and 17 and the waist cover body 3 are closed, the wall part 18 is made easy to bend inward by the protruding part 15 of the hinge part 4.

Therefore, in this embodiment, it is possible to make the rear wall portion 16 thicker than in the first embodiment.

It should be noted that the structure and effects of the compact container according to the second embodiment other than those described above are substantially the same as those of the first embodiment, so explanations thereof will be omitted.

FIG. 5 shows a third embodiment of the present invention, in which a horizontal split groove 20 is provided in the pin fitting hole 19 of the hinge portion 4 of the lid body 3.
is formed so that this groove 20 can be expanded elastically.

When assembling, the bottle 5a is fixed in advance to the rear end of the container body 1, and the split groove 20 is forcefully expanded while being press-fitted into the bottle 5a, and the pin-fitting hole 19 is fitted into the bottle 5a.

After that, when the lid 3 is closed, the protrusion 15 of the hinge 4 of the lid 3 presses the rear wall 16 of the container body 1 and elastically deforms it, and the pin fitting hole 19 of the lid 3 is closed. The grooves 20 are also expanded slightly to store elastic energy there.

Push the bushing piece 10 inward and press the first button. protrusion 8
When the engagement with the second projecting piece 11 is released, the lid body 3 opens vigorously due to the force generated by the elastic return of the rear wall portion 16 and the elastic return of the split groove 20 of the bottle fitting hole 19. It will be done.

The other configurations and effects are the same as those of the first embodiment, so their explanations will be omitted.

FIG. 6 shows a fourth embodiment of the present invention, and the compact container of this embodiment is a combination of the second embodiment shown in FIG. 4 and the third embodiment shown in FIG. A flexible wall 18 defined by the slint t-1 hoo 1 is formed on the rear wall 16 of the lid 3, and a horizontal split groove 20 is formed in the pin fitting hole 19 of the hinge 4 of the lid 3. It forms.

That is, when the lid 3 is closed to the container body 1, the flexible wall portion 18 is closed by the protrusion 15 of the hinge portion 4 of the lid 3.
is elastically deformed inward and the pin fitting hole 1 of the lid body 3 is
The grooves 20 of No. 9 are also expanded elastically, and elastic energy is stored in the deformed portions of both 18 degrees and 20 degrees.

Here, push the bushing piece 10 inward and press the first projecting piece 8.
When the engagement with the second projecting piece 11 is released, both the above-mentioned 18,
The lid body 3 is opened vigorously as the lid 20 returns elastically.

The other configurations and effects are the same as those in the first embodiment, so their explanations will be omitted.

As described above, in the compact container of the present invention, the protrusion 15 is integrally formed near the pivot point of the lid 3, and the protrusion 15 defines a recess in the container body 1 when the lid 3 is in the closed position. The rear wall 16 is pressed and slightly elastically deformed, and at the same time as the engagement between the first protrusion 8 of the lid 3 and the second protrusion 11 of the container body 1 is released, the rear wall 16 is pressed. Since the lid 3 is flipped up and opened via this protrusion 15 by elastic return, the opening angle of the lid 3 is large, and the lid 3 can be easily opened for subsequent makeup.
The operation of opening the mirror 6 at a predetermined angle and setting the mirror 6 becomes extremely simple.

In addition, since all the necessary parts for flipping open the lid 3 are integrated with the lid 3 or the container body 1, additional elastic members such as special springs are not required, and manufacturing and assembly are possible. It can be made into a simple and low-cost compact container.

Preferably, a pair of vertical slits 17-17 are formed in the rear wall 16 of the container body 1, and the protrusion 15 of the lid is pressed against the wall 18 between the pair of slits.

Alternatively, a horizontal groove 20 is formed in the pivot portion of the lid 3, and the groove 20 of the pivot portion is elastically expanded when the lid 3 is in the closed position.

In these cases, elastic deformation of the rear wall portion 16 or the pivoting portion of the lid body 3 is likely to occur, so that the protruding portion 15 of the lid body 3 is easily attached to the rear wall portion 16 of the container body 1. The resistance when closing the lid 3 while pressing can be reduced, and the angle when opening the lid can be made even sharper.

It should be noted that various modifications of the present invention are possible in addition to the above embodiments. For example, a second protrusion that engages with the first protrusion 8 of the lid 3 may be integrally formed on the edge of the container body 1. The bushing piece is formed from a piece having a tapered surface on its upper surface, and when this bushing piece is pressed inward, the claw piece 7 of the lid body 3 is pushed upward by the tapered surface, and the above-mentioned first The engagement between the protruding piece and the second protruding piece may be released.
