Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compact container for solid cosmetics such as eye shadow, eyeliner, foundation, powder, etc. In particular, the present invention relates to a compact container for solid cosmetics such as eye shadow, eyeliner, foundation, powder, etc. This relates to an airtight compact container that can also accommodate food.

In general, in compact containers containing solid cosmetics as described above, when using an applicator such as a puff, the solid cosmetics remain as a powder, so if you put the top lid in a band bag etc. while carrying it, As is well known, it has the disadvantage that it is scattered through the gap with the lower lid and contaminates the inside of the band bag.

Moreover, such conventional compact containers cannot be used at all when the cosmetic is volatile.

Furthermore, when the container is accidentally dropped into the liquid, the liquid penetrates into the cosmetic and causes it to dissolve or change in quality.

The present invention provides an airtight compact container that reliably eliminates the above-mentioned drawbacks and maintains appropriate airtightness. This makes it possible to use solid cosmetics having the following characteristics, and enables a wider range of use as a portable compact.

For this reason, an elastic backing is provided between the upper and lower lids,
Some containers are designed to seal the inside when the container is closed, but the top and bottom lids of this type of container are usually hinged to each other at one end. When the two are pressed together to close, the aforementioned elastic backing is gradually subjected to a pressing force starting from the portions closest to the hinge.

Therefore, the elastic backing tends to be compressed and deformed from the portion near the hinge toward the free end of the lid, and the sealing effect is forced to deteriorate during long-term use.

The present invention also aims to provide a means for appropriately eliminating the above-described deformation of the elastic backing.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

In the known device shown in FIGS. 1 and 2, 1 is a general term for a compact container, and the container 1 consists of an upper lid 2 and a lower lid 3, which are pivoted by a hinge pin 4, and the free ends of both 2, 3 teeth,
The hook mechanism 5 ensures secure locking.

Reference numeral 6 denotes an inner tray, which stores cosmetics therein and is fitted into the recess 8 of the lower lid 3.

Reference numeral 9 denotes a mirror, which is fixed in a recess 10 of the upper lid 2 via a mirror stopper 11.

Reference numeral 12 denotes an elastic backing provided so as to surround the inner plate 6, which is airtightly fitted into the groove 13, protrudes above the inner surface 3' of the lower lid 3, and has a so-called zero-rib type top edge 12'. form,
It is opposed to the inner plane 2 of the upper lid 2.

13 is a puff. Therefore, as is clear from FIG. 2, when the hook mechanism 5 is locked by pinching the upper and lower side lids 2.3 using the hinge pin 4 as a pivot, the elastic backing 120
As a result of the top edge 12' coming into pressure contact with the inner surface 2' of the upper lid 2, the inside of the container 1 bordering on the elastic backing 12 is reliably isolated from the outside and hermetically sealed.

As mentioned above, it is possible to seal the inside of the container by interposing an elastic backing between the upper and lower lids, but in this case, the difference in opening and closing of the upper and lower lids is due to their hinge pins. As mentioned above, since the elastic backing is lifted up and down using the pivot point 4 as the pivot, the pressing force is first applied to the elastic backing from the part near the hinge pin, and then gradually moves to the outer end, and when it is opened, the load is released. is done in reverse.

Therefore, the elastic backing itself has a defect in that it is easily deformed due to the movement of the pressing force.

The embodiments shown in FIGS. 3 and 4 are constructed to eliminate this defect, and similar members to those in FIGS. 1 and 2 are designated by the same numbers.

This embodiment differs from the previous example in that an inner lid 15 is provided, and the inner lid 15 is supported on the upper lid 2 by a support shaft 16 parallel to the hinge pin 4.

That is, the inner lid 15 is provided so as to be swingable within the recess 2' using the support shaft 16 as a fulcrum.

Therefore, when the upper cover 2 and the lower cover 3 are closed around the hinge pin 4, the elastic backing 12 of the inner cover 15 near the hinge pin 4 starts to come into pressure contact with the inner plane 3' of the lower cover, but the support shaft This forced pressure is avoided by the expansion movement of the inner lid 15 around the center 16, and the upper lid 2 and the lower lid 3 reach approximately parallel.
As the hook mechanism 5 locks the elastic backing 12, the elastic backing 12 is brought into pressure contact with the inner surface, and sealing is performed.
Since non-uniform pressing force on 2 is eliminated, deformation thereof can be prevented.

The embodiment of FIG. 5 has the inner lid 15, and the third
, 4 is similar to the one shown in the figure, but the inner lid 15 has a leaf spring 11.
The upper cover 2 is secured by the elastic spring and the stop frame 18.
A gap 19 is provided at a distance between the two.

Therefore, when the container 1 is closed, pressure contact starts from the backing portion 12'' of the inner lid 15 near the hinge pin 4, as in the previous example.
The inner lid 15 expands and absorbs the pressing force using the elasticity of the leaf spring 11, and the elastic backing 12 is evenly pressed in the final stage of closing when the upper lid and lower lid are substantially parallel.

Next, in the embodiment shown in FIG. 6, the center of the inner cover 15 is supported by the upper cover 2 with a flexible member 20, and since there is a gap 19 between the inner cover 15 and the upper cover 2, The lid 15 is configured to be able to swing freely within the allowable range of the gap 19.

Therefore, as in the embodiment shown in FIG. 5, the uneven suppressing effect on the elastic backing 12 caused by the upward and downward movement of both the upper and lower lids 2 and 3 is absorbed by the swinging of the inner lid 15, and finally the average suppression is applied. It is something.

There are various types of elastic backing that can be considered, such as a two-strip type in which two ribs are formed, each having a circular cross section and a chevron-shaped cross section, and many others. It is included in

As described above, according to the hermetic compact container of the present invention, it is possible not only to reliably prevent cosmetic powder from scattering outside the container, but also to store volatile cosmetics, which was not considered in the past. It has excellent features that make it possible to perform the following tasks, and the deficiencies of the conventional compact mentioned at the beginning can be reliably eliminated.
