Description

[Detailed Description of the Invention] The present invention relates to a compact container, and an object of the present invention is to firmly assemble a drum plate to a compact body and to facilitate removal thereof.

Conventionally used compact containers generally have a structure in which a drum tray containing cosmetics is incorporated into the compact body.

This is because the cosmetics stored in this type of compact container require the above-mentioned drum tray due to their special molding, and the cosmetics that are molded into a certain shape are extremely fragile. To,
This is due to the fact that it is extremely difficult to remove it from the drum tray and handle it alone.

When such a drum plate is assembled into the compact body, the assembly must be firm, and even the slightest wobbling is not allowed. dimensional accuracy is required.

In addition, the compact body is extremely beautiful and well-shaped as a cosmetics container, and is therefore expensive, so it is uneconomical to discard it after the cosmetics are used up, and It is desirable to be able to replace the drum tray in which the material is stored.

In other words, the drum plate is required to be able to be firmly assembled and fixed to the compact main body while allowing a relatively large molding dimensional error, and to be able to be attached and detached as the case requires.

The present invention relates to a compact container devised to meet the above-mentioned conventional requirements, in which the outer peripheral surface of the peripheral wall of the drum tray that directly stores cosmetics is molded from a synthetic resin material that can be elastically deformed. The outer circumferential surface of this peripheral wall portion is formed of an elastically deformable synthetic resin material, and the outer circumferential surface of the drum plate and the inner circumferential surface of the circumferential wall of the compact main body are provided with locking portions that lock each other. A flange is provided around the upper end of the outer circumferential surface of the drum plate, which is a part on which an external force is applied to forcibly release the engagement of the stop part.

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

First, the compact main body 1 is a container 2 in the shape of a short cylinder with a bottom.
It has a structure in which a lid body 3 is connected to the lid body 3 via a hinge,
In the illustrated embodiment, a notch 5 is formed in the center of the peripheral wall 4 at the rear of the container 2, which has the shape of a short rectangular cylinder with a bottom, and a step 6 is formed in the upper end of the inner periphery of the peripheral wall 4 along the circumferential direction. A locking groove 7 is horizontally provided as a locking portion along the circumferential direction at the lower end of the inner surface at the center of both front and rear ends of the peripheral wall 4.

A hinge piece 8 that is integrally suspended from the lid body 3 is fitted into the notch 5 of the peripheral wall 4, but even in this fitted position, the rear end of the peripheral wall 4 is still connected to the stepped portion 6.
It is cut out to a lower level.

Next, the drum tray 9 has a short cylindrical shape with a bottom corresponding to the inner peripheral shape of the peripheral wall 4 of the container 2, and is composed of a short cylindrical body 10 with a bottom and a lip body 13.

The bottomed short cylindrical body 10 made of thin metal plate has a bottom plate 11 and a low cylindrical wall 12 erected from the peripheral end of the bottom plate 11, similar to a conventional drum, and can be formed by impact molding, press molding, etc. However, there is no need to perform post-processing on the opening edge as in the conventional method, and the opening edge may simply be left in the cut state after molding.

The rim body 13 is molded from a relatively soft synthetic resin material, and is integrally fixed to the cylindrical wall 12 so as to cover at least the upper end surface and outer peripheral surface of the cylindrical wall 12 of the bottomed short cylindrical body 10. has been done.

In the illustrated embodiment, the mouth rim body 13 is a short cylindrical body 1 with a bottom.
an inner wall portion 14 having an outer diameter equal to an inner diameter of 0;
It is a double-walled short cylinder body in which an outer wall part 15 having an inner diameter slightly larger than the outer diameter of the bottomed cylinder body 10 is integrally installed via a top wall part 16, and the top wall part 16 is connected to the outer wall part 1.
The flange 17 extends outward from the flange 5 and is provided around the periphery.

After the bottomed cylindrical body 10 and the lip body 13 are molded completely separately, they are fitted together and ultrasonically welded to form the drum plate 9.

As described above, since the lip body 13 is positioned facing at least the upper end surface and the outer peripheral surface of the cylinder wall 12 of the bottomed cylinder body 10, the height and outer diameter dimensions of the drum plate 9 are determined by the final size. is set by this lip body 13.

In the illustrated embodiment, the bottomed cylindrical body 1 of the lip body 13 is
0 is achieved by the inner wall part 14 and top wall part 16 of the mouth rim body 13, and there is a gap 18 between the outer wall part 15 and the cylinder wall 12 of the bottomed short cylinder body 10. A tongue piece 19 is formed at the center of the front end and the rear end of this outer wall portion 15 in correspondence with the locking groove 7 provided in the peripheral wall 4 of the compact main body 1.
A notch is formed, and a locking strip 20 that locks into the locking groove 7 is provided at the lower end of the outer surface of the tongue piece 19 as a locking portion.

This locking strip 20 has an upper surface and a lower surface each tapered at a predetermined angle.

Now, the drum plate 9 is attached to the compact main body 1 mentioned above.
The tongue piece 19 of the mouth rim 13 of the drum tray 9 has a gap 18, so a locking strip 20 is formed on the inner surface of the peripheral wall 4 of the compact main body 1. When they come into contact, they are elastically deformed inward, and the locking strips 20 fit into and lock in the locking grooves 7, thereby elastically returning and locking.

In this case, since the lower surface of the locking strip 20 is a tapered surface, the tongue piece 19 can be easily inserted into the peripheral wall 4.

In addition, the flange 17 of the mouth rim body 13 is fitted onto the stepped portion 6 of the peripheral wall 4 in the above-mentioned locked state, but since the notch 5 is provided at the rear end of the peripheral wall 4, The side surface of the flange 17 portion at the rear end is exposed.

Therefore, by locking the locking strip 20 into the locking groove 7 and fitting the flange 17 into the stepped portion 6, the drum plate 9 is firmly and easily assembled and fixed to the compact main body 1.

In addition, when this drum plate 9 is assembled, the rear end of the flange 17 of the mouth edge body 13 of the drum plate 9 is exposed from the peripheral wall 4 of the compact main body 1 at an inconspicuous portion. If you pull up the flange 17 with your fingers,
Since the upper surface of the locking strip 20 is a tapered surface, the tongue piece 19 is elastically deformed inward, and the drum plate 9 is released from the locking groove 7 of the locking strip 20 and detached from the compact body 1. will have to leave.

If the compact main body 1 does not have a bottom wall and is simply shaped like a short cylinder, it will be possible to release the lock by forcibly deforming the tongue piece 19 from below.

Furthermore, since the drum dish 9 is fixed to the cylinder wall 12 of the short cylinder 10 with a bottom in a state that covers the mouth rim 13 made of synthetic resin, the short cylinder with bottom made of thin metal plate 1
There is no need to perform post-processing on the cut portion of 0, and the outer diameter of the drum plate 9 is finally set by the lip 13, so a short cylinder with a bottom formed with a single dimension can be used. Even if it is a body 10, it is possible to obtain drum plates 9 of various sizes by simply setting the dimensions of the mouth rim body 13 to be assembled thereto. Since it is only necessary to prepare the mouth rim body 13, the molding is simple, and the expensive bottomed short cylinder body 10 is not wasted, making it extremely economical.

As is clear from the above description, according to the compact container of the present invention, it is easy to attach and detach the compact body and the drum tray, so it is easy and economical to replace the drum tray that stores cosmetics. There is no need to discard the expensive compact body, the assembly of the drum plate to the compact body is extremely strong despite being removable, and the structure is simple and easy to mold. It has an effect.
