DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact container having an improved hinge structure.

[0002]

2. Description of the Related Art Conventionally, a compact container has a structure in which a container body for storing cosmetics and a lid for opening and closing the container are connected via a hinge portion.

By the way, the hinge portion of the compact container has conventionally been devised in various ways. In addition to the simple hinge function, the opening / closing operation of the lid can be automatically performed by biasing force. It is considered useful.

[0004]

However, in such a conventional compact container, a separate urging means such as a spring is provided in order to apply an urging force to the lid. For this reason, the number of parts is increased, and the cost is inevitably increased due to an increase in the number of assembling steps. In addition, since the compact container is relatively small as a whole, the structure of the hinge portion is small, so that it is extremely difficult to assemble the urging means, and it is difficult to introduce automation for this assembling operation. Met. as a result,
There has been a problem that the assembling work of the hinged part must necessarily rely on manual work, and the productivity is not good.

[0005] In view of the above-mentioned problems, the present invention reduces the number of parts of the hinge portion while ensuring good opening and closing operability of the lid, and greatly improves the workability of assembling. It is an object to provide a compact container that can be achieved.

[0006]

In order to achieve the above object, the present invention provides a compact container in which a lid for opening and closing a container body is rotatably attached to the container body via a hinge. A pin insertion hole which is formed so as to be inclined with respect to a rotation axis of the lid and penetrates from the lid to the container main body, and which communicates linearly with the lid closed; , And a hinge pin inserted into the pin insertion hole.

In addition, it is desirable to form a relief portion when the hinge pin is bent, at a boundary between the container body and the lid body through which the pin insertion hole is formed.

[0008]

According to the above construction, the compact container of the present invention is configured by inserting a hinge pin into a pin insertion hole formed between the container body and the lid. The pin insertion hole is inclined with respect to the rotation axis of the container body and the lid.

Therefore, when the lid is opened while the hinge pin is inserted through the pin insertion hole, the direction of the pin insertion hole changes between the container body and the lid, and the pin insertion hole is bent.
Then, the hinge pin inserted into the pin insertion hole is forcibly bent with the bending of the pin insertion hole. At this time, the hinge pin is plastically deformed while exhibiting elasticity. Thereafter, when the lid is closed again, the hinge pin is returned to a substantially straight shape while accumulating a resilient force in the bending direction in the pin insertion hole that has been returned to the straight shape. Here, since the bent portion has elastic deformation capability, the hinge pin exerts a resilient force in the bending direction and a resilient force in the torsional direction accompanying the turning operation of the lid. These resilient forces act between the container body and the lid inside the pin insertion hole.

Therefore, when the lid is opened and closed after the hinge pin is once bent, when the pressing force is released from the state in which the lid is pressed in the closing direction, the elastic member in the bending direction generated in the hinge pin is generated. The lid automatically opens at a predetermined angle due to the springback caused by the elastic force in the torsional direction. Further, when the lid that has been opened by a predetermined angle in this manner is further opened, a rotational resistance is generated between the lid and the container body due to the elastic force of the hinge pin, and the lid is attached to the container body. On the other hand, it can be stopped at any open position.

Further, the pin is reliably held in the pin insertion hole due to the bending of the pin with respect to the rotation axis, so that the pin is dropped from the hinge portion, that is, from the pin insertion hole with the opening and closing operation of the lid. Thus, the productivity can be improved and the cost can be reduced by eliminating the necessity of employing other removal prevention means.

[0012] Furthermore, by forming a relief portion when the hinge pin is bent at the boundary between the container body and the lid through which the pin insertion hole passes, the hinge pin can be easily bent. When the hinge pin rotates together with the lid in the folded state, the bent portion can be rotated without difficulty.
