Description

[Detailed description of the invention] ≪Industrial application field≫ This invention relates to a self-opening compact container, and more specifically, a container body for storing cosmetics and a lid body are connected at their respective rear ends. An automatic opening type in which the push piece is movably attached to the front edge of the container body, and the lid is opened by pressing the push piece inward when the lid is in the closed position. This relates to compact containers.

<<Prior Art>> In the above-mentioned conventional self-opening compact container, a separately formed spring piece or the like is attached to the rear part of the container to constantly bias the lid in the direction of opening. There is an automatic opening type compact container which opens the lid at the same time as the engagement with the lid is released.

However, in this self-opening compact container, a separately formed spring piece etc. must be attached to the rear part of the compact container, so other mounting parts etc. are also required, making the structure complex and requiring assembly work. There was a problem in that it was not only difficult, but also increased costs due to an increase in the number of parts.

≪Problems to be solved by the invention≫ The present invention was made in view of the above-mentioned problems, and its purpose is to enable the lid to be opened automatically without attaching special parts as in the past. Therefore, it is an object of the present invention to provide a self-opening compact container which has a simple structure, can be easily assembled, and can reduce costs.

<<Means for solving the problem>> In order to achieve the above object, according to the self-opening compact container of the present invention, a hinge piece is integrally formed to hang down from the rear end of the lid body, and the lid A metal plate is attached to the body, which extends partially from the rear upper surface of the body through the rear end surface of the hinge piece to the inside of the hinge piece, and the free end of this metal plate is attached to the inner surface of the hinge piece and the back of the container body. It is inserted into the space between the container and the end wall, and when the lid is in the closed position, the rear end of the metal plate is elastically deformed by the rear end wall of the container body, so that the lid is constantly biased in the opening direction. This is how it happens.

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

1 to 3 show a preferred embodiment of the self-opening compact container according to this invention. As shown in these figures, the container body 10 is
It is formed into a substantially rectangular shape, and a recess 11 in which cosmetics and the like are stored is formed on its upper surface. The front end of the container main body 10 is a flange portion 12, and an insertion hole 13 is bored in the center of the flange portion 12. In addition, at the center of the rear edge of the container body 10,
A first concave cutout 14 is formed, and
A second concave notch 14 is provided at the center inside the first concave notch 14.
A concave cutout 15 is formed.

This lid body 20 has substantially the same planar shape as the container body 10, and has a mirror 21 adhered to its inner surface. A hinge piece 22 is integrally formed to hang down at the center of the rear end of the lid body 20, and this hinge piece 22 enters the first concave notch 14 of the container body, where the hinge pins 23-23 The lid 20 is screwed onto the container body 10 so as to be openable and closable. In addition, the lid body 2
A claw piece 24 is formed hanging down from the center of the front end of 0, and a first engagement protrusion 25 is integrally formed inside the lower end of the claw piece 24. And this nail piece 24
can be inserted into an insertion hole 13 formed in the front end flange portion 12 of the container body 10 when the lid body 20 is closed.

On the other hand, the lower surface of the container body 10 is covered with an outer box 30, and this outer box 30 covers the container body 10.
It has approximately the same planar shape as , and a through hole 31 is bored in the center of its front end wall. Also, outer box 3
The center portion of the rear end edge of the container body 10 is cut out to have substantially the same shape as the first concave cutout portion 14 of the container body 10 .
Further, a push piece 40 is disposed within a space formed by the front end flange portion 12 of the container body 10 and the front portion of the outer box 30.

The push piece 40 includes a wing-shaped portion 41-41 extending in the left-right direction and a pressing portion 42 protruding forward.
and a claw piece 43 standing upwardly. The tip of the wing-shaped portion 41-41 is curved rearward and is formed to be elastically deformable, and the claw piece 43
A second engagement protrusion 44 is integrally formed in front of the upper end. Furthermore, when the push piece 40 is placed inside the outer box 30, the push piece 40 is pushed forward by the wing-shaped parts 41-41, so that the pressing part 42 is projected forward from the through hole 31 formed in the outer box 30. Furthermore, when the lid body 20 is closed, the second engaging protrusion 44 is positioned so as to engage with the first engaging protrusion 25 formed on the lid body 20. .

In the embodiment of the present invention, the upper surface of the lid 20 is covered with an outer lid 50 made of metal, and the outer lid 50 has substantially the same planar shape as the lid 20. The center portion of the rear end wall of the outer lid 50 extends downward to cover the curved lower end of the rear end surface of the hinge piece 22, and then extends upward to separate it slightly from the inner wall surface of the hinge piece 22 forward. The free end is an elastic end piece 51.

The hinge piece 22 of the lid body 20 covered by the outer lid 50 as described above was positioned within the first concave notch 14 of the container body 10, and the hinge piece 22 was screwed onto the container body 10. At times, a box-shaped cavity is defined between the notch 15 and the hinge piece 22, and the elastic end piece 51 of the outer lid 50 is accommodated within this box-shaped cavity. When the lid 20 is in the closed position, the end of the elastic end piece 51 comes into contact with the back wall of the second concave notch 15 of the container body 10, is pressed rearward, and is elastically deformed.

Although the outer cover 50 covers the entire upper surface of the cover 20 in the above embodiment of the present invention, it may be formed to cover only the rear part of the cover 20.

<<Operation>> Now, when the lid body 20 is closed, the claw piece 24 of the lid body passes downward through the insertion hole 13 of the front end flange portion 12 of the container body 10, and the first engagement protrusion 25 formed on the claw piece 24 is the second engaging protrusion 4 of the push piece 40
4, the lid 20 assumes a closed position relative to the container body 10 as shown in FIG. In this closed position, the elastic end piece 51 of the outer lid 50
is elastically deformed rearward by the back wall of the second concave notch 15 of the container body 10, so that a force acts on the elastic end piece 51 in the direction of opening the lid 20. From this state, by pressing the pressing part 42 of the pusher piece 40 inward as shown in FIG. The lid body 20 is automatically opened by the elastic restoring force.

<<Effect of the invention>> As described above, in the present invention, the end of the metal plate coated on the top surface of the lid body is bent, and the lid body is automatically opened by the elastic force possessed by the metal plate. Because of this, there is no need for special parts for opening the lid, the structure is simple and compact, it can be easily assembled, and the cost is low.
Furthermore, since the metal plate has excellent decorative properties, it can exhibit various effects such as an excellent appearance.
