Description

[Detailed Description of the Invention] This invention relates to a compact container, and more particularly to a self-opening compact container in which the lid can be automatically opened to a sufficient angle with one touch.

Conventionally, a compact container has a hinge mechanism at the rear end of the container body and the lid, which are pivotally connected to each other, and the opening operation is performed by holding the container body with one hand and opening the lid with the other hand. This was common, and it was inconvenient that both hands had to be used to open the door.

Thereafter, the applicant provided a movable push piece at the front end of the container body, and provided a protruding locking piece on the front end of the lid body, which was opposite to the push piece and could be engaged with a protrusion provided on the container body. A so-called push-piece type compact container has been proposed in which the container is closed by engaging these, and the push-piece can be opened with one touch by pressing the push-piece inward.

However, even in such push-piece type compact containers, the lid cannot be opened sufficiently by simply pressing the push-piece inward, which causes inconvenience during use. It was hoped that improvements would open up new opportunities.

This invention was developed against this background, and its purpose is to create a self-opening compact container that has a relatively simple structure but can be opened automatically to the extent that it is not inconvenient to use. It is located in a place that provides.

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

1 to 4 show an embodiment of the self-opening compact container of this invention.

The self-opening compact container shown in the figure is first made of synthetic resin or the like and consists of a container body 10 for storing cosmetics, and a lid 12 that closes this and houses a mirror 11 inside. A recess is formed in the rear end edge, a block body 16 is formed hanging from the rear end edge of the lid body 12, and the block body 16 is fitted into the recess and the pin 17 is inserted to connect the pivot joint part 18.
This allows them to be connected so that they can be opened and closed.

A push piece 20 movable in the front-rear direction is attached to the front edge of the container body 10, and a first protrusion 22 is formed, while a second protrusion is formed on the front edge of the lid 12. A piece 24 is formed to hang down, and a locking piece 26 is integrally formed on the inner surface thereof.

With this configuration, when the lid body 12 is in the closed position, the first projecting piece 22 and the locking piece 26 engage with each other to maintain the closed position and push the push piece 20 inward. by doing,
The lid 12 can be opened slightly.

The compact container shown in the figure has the following features compared to the conventional container described above.

That is, a hollow part 28 with an open upper end is formed above the block body 16, which forms the pivoting part 18 of the lid body 12, and a hollow part 28 with an open upper end is formed.
The portion facing the rear end wall 30 of the recess, that is, the inner wall of the block body 16, is cut into a U-shaped slit 32.
By providing a tongue piece 34, it is partially cut out to form a flexible tongue piece 34 in the front and rear, and a convex protrusion 36 that projects slightly outward is integrally formed at the lower end of this tongue piece 34. There is. (See FIG. 2) The hollow portion 28 located behind the tongue piece 34 is filled with an elastic body 38 such as urethane rubber from its upper opening. (See Figure 3) Also, the upper surface of the lid 12 and the hollow part 28
A top plate 40 is attached with an adhesive or the like so as to cover the upper surface of the top plate, and this top plate 40 can also be used as a decorative plate.

Now, in the configuration as above,
When the lid 12 is closed to the container body 10, the convex protrusion 36 of the tongue piece 34 comes into contact with the rear end wall 30 of the container body 10 and is elastically deformed rearward. .

As a result, the hollow portion 28 at the rear of the tongue piece 34 is filled with the elastic body 38 as described above, and the elastic body 38 is compressed by the rearward elastic deformation of the tongue piece, resulting in this state. As a result, the first projecting piece 22 of the container body 10 and the locking piece 26 of the lid 12 are engaged with each other with a click feeling, and are maintained in the closed position.

In this case, the elastic body 38 is in a compressed state as described above, and the elastic force of the elastic body 38 itself and the elastic force of the tongue piece 34 exert a force to return it to its original state.

This elastic force is applied to the rear end wall 30 of the container body 10.
At the contact point of the convex protrusion 36 of the tongue piece 34, a force acts to push the rear end wall 30 inward.

Therefore, the push piece 20 is pressed inward from the closed position, and the first projecting piece 22 and the locking piece 2
When the engagement state of the push piece 6 is released, the elastic force acts as a rotational moment in the direction of opening the lid body 12 using the pin of the pivot portion 18 as a fulcrum, and the moment the push piece 20 is pressed inward, the lid closes. It becomes possible to open the body 12 automatically and to an extent that does not cause any inconvenience in use.

The elastic force that opens the lid 12 in this way is determined by the material of the elastic body 38, the compressive force, etc., and when the lid 12 opens, the container body 10
These are selected so that there is no risk of the cosmetics inside scattering and the lid 12 can be opened sufficiently.

FIG. 5 shows a second embodiment of the self-opening compact container of this invention. To explain only the features of the self-opening compact container shown in the figure, the tongue piece 34 formed on the inner wall of the block body 16 has an inverted U shape, unlike the first embodiment.
It is formed by providing a letter-shaped slit, and a convex projection 36 is provided at the upper end of the tongue piece 34 to provide flexibility in the front and rear directions.

With such a configuration, it is the point of action of the rotational moment that opens the lid 12 as described above. Convex projection 36 of tongue piece 34 and container body 10
Pressure contact point with rear end wall 30 and pivot joint 1 serving as a fulcrum
The distance between the pins 17 of 8 is increased, and it becomes possible to sufficiently open the lid 12 to a desired angle even with a relatively small elastic force.

FIG. 6 shows a third embodiment of the self-opening compact container of this invention.

Only the features of the self-opening compact container shown in the figure will be described below.

In other words, this self-opening compact container is
The formation of the tongue piece 34 that enables automatic opening is similar to that of the second embodiment, but the hollow part 28 located behind the tongue piece 34 and filled with the elastic body 38 is
It is located at an opening at the lower tip of the block body 16.

With such a configuration, the elastic body 38
The insertion work into the hollow portion 2 becomes extremely easy, and the top plate 40 as in the above embodiment is not required, making it possible to further simplify the structure.

As described above, this invention allows the self-opening compact container to be made hollow above the rear end pivoting part of the lid body, and by partially cutting out the part that opposes the rear end wall of the container body so that it can be moved forward and backward. Forming a flexible tongue piece, filling the rear hollow part of the tongue piece with an elastic body,
When the lid body is closed to the container body,
The tongue piece is configured to press against the rear end wall of the container body and compress the elastic body, and the lid body can be opened with one touch due to the return force of the elastic body from compression, making it inconvenient to use. It can be opened automatically to a sufficient angle that you won't feel it.
