Description

[Detailed Description of the Invention] The present invention relates to a compact container made of synthetic resin, and its purpose is to suppress damage to the hinge piece that connects the container body and the lid plate as much as possible.

A compact container is composed of a container body into which a drum for storing cosmetics is fitted, and a lid plate.The container body and lid plate are generally connected by a hinge. This method is time-consuming and has the disadvantage that the container body and lid plate must be manufactured separately.

Therefore, if the container body and the lid plate are integrally molded using a hinge piece, there will be no assembly work and production will be easier, but since the hinge piece is a part that rotates when the lid plate is opened and closed, it is difficult to use. Therefore, it is conceivable that damage such as tearing of thin parts due to gradual fatigue may occur.

In addition, when the container is closed, the conventional hinge, which is composed of a thin wall, protrudes to the rear of the container and has quite acute angles on both sides, so it can easily get caught on other items. Therefore, not only is the hinge itself easily damaged, but it also causes inconveniences such as damaging other articles and injuring the user.

The present invention was devised to solve the above-mentioned conventional drawbacks and inconveniences, and it connects the container body and the lid plate through a hinge piece, and also bends and bends the hinge piece to allow multiple rotations. The rotation amount of each rotating portion is reduced to reduce the fatigue level of each portion.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a rectangular thin box-shaped synthetic resin container body into which a drum for storing cosmetics is fitted; 4 are installed in succession.

The hinge piece 3 and the rear wall 2 are connected to each other by a linear thin part 5 at the rear edge position of the upper end surface of the rear wall 2, and the hinge piece 3 and the cover plate 4 are connected to each other at the rear edge of the upper end surface of the rear wall 2. The upper edge position of the end surface is continuous with a linear thin wall portion 6, and furthermore, a thin wall portion 7 is formed at the center of the hinge piece 3 in parallel to the thin wall portions 5 and 6, and the hinge piece 3 is connected to the thin wall portion 6 in the form of a line. The portion 7 is bent inward.

Therefore, when the cover plate 4 is closed, as can be understood from FIG.
The central thin portion 7 is bent inward.

Then, when the cover plate 4 is opened, the thin parts 5, 6, 7
All of them rotate, albeit slightly, and as a result, the lid plate 4 can be rotated to a desired angle (see FIG. 3).

Further, in the illustrated embodiment, a locking piece 8 is attached to the front end of the cover plate 4.
A notch 9 is provided at the front end of the central portion of the container body 1, and the locking piece 8 engages with the notch 9 to maintain the closed state of the lid plate 4.

However, since the lid plate 4 is continuous with the container body 1 via the hinge piece 3, the lid plate 4 is
There is a risk that the above-mentioned engagement may be released due to sliding forward.

Therefore, in the illustrated example, the stepped portion 10 is formed by cutting out the inner surface of the upper end of the peripheral wall of the container body 1, and the lid plate 4 is formed to be slightly smaller than the container body 1, so that when the lid plate 4 is closed, the lid plate 4 The lid plate 4 is fitted into the container body 1 in such a manner that it rests on the stepped portion 10, thereby preventing the lid plate 4 from shifting.

Alternatively, a step may be formed by cutting out the outer periphery of the upper end of the peripheral wall of the container body 1, and a peripheral wall with a low height and width may be provided on the peripheral edge of the lid plate 4, and the lid plate 4 may be fitted over the lid plate 4. Dew.

As is clear from the above description, in the compact container of the present invention, the container main body 1 and the lid plate 4 are connected via the hinge piece 3, and the thin parts 5, 6, and 7 of the hinge piece 3 are connected to each other via the hinge piece 3. They are provided in three parallel places, and when the cover plate 4 is opened and closed,
6 and 7 are designed to rotate respectively.

Therefore, even if the cover plate 4 is repeatedly opened and closed sufficiently during use, the rotating parts are divided into three parts, so that each thin part 5, 6, 7
The rotation angle is extremely small, and therefore the material does not become fatigued since it does not receive a large load during rotation.

In addition, since the lid plate 4 and the container body 1 are integrally molded via the hinge piece 3, not only is molding easy, but since no hinge shaft is incorporated, no gap is formed. This will improve the sealing effect and prevent fragrance from leaking out.

Furthermore, since the central thin wall portion 7 is bent inward, the hinge piece 3 does not protrude to the rear of the container when the container is closed, which prevents the hinge piece 3 from getting caught on other items. This inconvenience does not occur, and safe and good usage conditions can be obtained, and the bending posture of the central thin wall portion 7 is opposite to the bending posture of the thin wall portions 5 and 6 on both sides. By the bending action of the thin parts 5 and 6 on both sides, the bending of the thin part 7 in the set direction is achieved reliably and stably, thereby providing the hinge piece 3 with stable hinge function operation. can be demonstrated.

Therefore, the present invention has many excellent functions and effects, such as a simple structure, easy molding, little damage to the hinge part even if the lid plate is repeatedly opened and closed, and easy to use. It is.
