Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a thin compact container with a three-layer structure in which a lid, a compact main body, and a puff container are connected in an openable and closable manner.

[Conventional technology]

Conventional compact containers for storing cosmetics, etc.
Depending on the purpose of use, it is required to be small and thin overall, but depending on the use,
There are cases where it is necessary to form a part for storing cosmetics and a part for storing puffs, and in this case, there is no choice but to have a three-layer structure including the lid.

Therefore, it is necessary to make the part of the inner plate into which the drum storing and holding the cosmetics is fitted as thin as possible.However, in the conventional structure, the part for storing cosmetics is formed in the center of the inner plate. In the recess,
The drum is inserted into it.

However, when this inner plate is molded from synthetic resin, the bottom wall of the concave portion must be made thicker to a certain extent in order to maintain the required strength, resulting in the compact container as a whole becoming thicker. I had no choice but to do so.

[Problem that the invention attempts to solve]

The present invention relates to a compact container devised to eliminate the above-mentioned conventional drawbacks and inconveniences, and the compact body is composed of an inner plate ring made of thin synthetic resin and an aluminum inner plate, The purpose is to form the entire compact container into a thin wall.

[Means for solving problems]

The structure of the compact container of the present invention will be explained below.

The compact container of the present invention has a three-layer structure in which a lid body 1, a compact body 2, and a puff storage body 3 are connected so as to be openable and closable, and the compact body 2 is composed of an inner plate ring 4 and an inner plate 9. .

A thin inner plate ring 4 made of synthetic resin has a hinge piece 5 formed at one end, a fitting opening 6 in the center, and a seal strip 7 provided around the upper surface of the periphery of the fitting opening 6. Furthermore, a fitting groove 8 is provided around the lower surface of the peripheral edge of the fitting opening 6.

The inner plate 9 made of aluminum has a short cylindrical body with a bottom and a hot melt seal 12 applied to the surface thereof, and a short cylindrical wall 1 having a height and width approximately equal to the depth of the fitting groove 8.
1 into the fitting groove 8 and thermocompression bonding,
It will be assembled to the inner plate ring 4, and the fitting opening 6 of the inner plate ring 4 and the bottom wall 10 of the inner plate 9 will form a space into which the drum 13 containing the cosmetics will be fitted.

[Effect]

That is, to assemble the inner plate 9 to the inner plate ring 4, the short cylindrical wall 11 is fitted into the fitting groove 8 and heated, the hot melt seal 12 is melted, and the fitting groove 8 is heated.
This is achieved by welding to the inner plate ring 4 of the part, and does not require high-temperature heating, so even if the inner plate ring 4 is thin, there will be no deformation or distortion due to heat, and the hot melt seal 12
By dissolving the short cylinder wall 11 and the fitting groove 8, the assembled portion becomes dense.

Since the depth of the fitting groove 8 and the height of the short cylindrical wall 11 are approximately equal, the lower surface of the inner plate ring 4 and the lower surface of the bottom wall 10 of the inner plate 9 are substantially flush with each other, ensuring a thin wall shape.

Further, the seal strip 7 of the inner plate ring 4 comes into contact with the inner surface of the lid 1 when the lid 1 is closed, thereby sealing the drum 13.

〔Example〕

In the illustrated embodiment, the hot mettle seal 12 in the inner tray 9 is arranged in a film form by coating or the like from the top surface of the bottom wall 10 to the inner peripheral surface of the short cylindrical wall 11 and the inner periphery of the short cylindrical wall 11. It melts at a relatively low temperature and is welded to the inner plate ring 4 within the fitting groove 8.

Further, the fitting groove 8 is formed on the lower surface of the inner plate ring 4 at the periphery of the fitting opening 6 of the inner plate ring 4. A cutout approximately as thick as the bottom wall 10 of the inner plate 9 is formed so that the lower surface of the inner plate ring 4 and the lower surface of the inner plate 9 can be flush with each other when the inner plate 9 is assembled.

[Effect of idea]

Since the compact container of the present invention has the structure described above, the inner plate can be easily and firmly assembled to the inner plate ring.
The inner plate ring does not undergo thermal deformation due to heating during assembly, and the compact body formed by the inner plate ring and inner plate is thin as a whole because the inner plate is made of aluminum, and is made of three layers. It can be made small even with a compact container,
It has many excellent functions and effects, such as a simple structure and easy molding.
