[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact container for holding volatile cosmetics, and more particularly to a solvent such as water or oil which has volatilized from the cosmetics in the container body and has condensed on the top surface of the lid. The present invention relates to a compact container capable of preventing the particles from dropping on the surface of cosmetics without any inconvenience.

[0002]

2. Description of the Related Art In recent years, cosmetics containing a large amount of solvents such as water and oil have become popular due to their good usability, and such cosmetics are held in compact containers with improved airtightness. , Has been commercialized. However, in such cosmetics, the solvent is easily volatilized, and the solvent volatilized inside the container comes into contact with the top surface of the lid and forms dew on the surface, which drops on the surface of the cosmetic without care ( There is a problem in that the surface of the cosmetic composition forms a stain of condensation and drastically impairs the appearance.

As a conventional method for preventing such condensation and dripping, a compact container as disclosed in Japanese Patent Application Laid-Open No. 7-184717 has been proposed. This compact container is attached between the cosmetic holding the moisture absorbent in the container body and the lid, more specifically on the top surface of the lid, and the moisture absorbent takes in the solvent volatilized from the cosmetic. And to prevent the solvent from dewing in the compact container.

[0004]

In such a conventional compact container, since a hygroscopic agent is exposed between the cosmetic and the lid, the solvent which evaporates upward from the cosmetic is efficiently taken in. On the other hand, it is necessary to attach the moisture absorbent to the top surface of the lid by forming the absorbent into a sheet or the like, and there has been a problem that the moisture absorbent is exposed to the lid, which impairs aesthetic appearance.

[0005] Therefore, an object of the present invention is to propose a compact container which can treat dew condensation on the top surface of a lid and maintain an aesthetic appearance without using a moisture absorbent.

[0006]

According to the present invention, there is provided a container body for holding a cosmetic containing a volatile solvent, and a lid, wherein the lid is composed of an outer plate and an inner plate. A dew condensation space is provided between the plate and the interior plate, and when the lid is closed, a ventilation hole communicating between the dew space and the container space formed between the interior plate and the container body is provided. The above problem has been solved by proposing a compact container for preventing condensation and dripping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a compact container according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a compact container according to the first embodiment, and FIG. 2 is a side sectional view of the compact container according to the first embodiment.

As shown in FIGS. 1 and 2, the compact container A comprises a container body 1 and a lid 2 for keeping the container body 1 airtight, and each is molded from a synthetic resin such as polypropylene. Hinge portions 1a, 2a are provided at one end of the container body 1 and the lid 2, and the two are pivotally connected by passing a rotating shaft 3 between them. An engagement protrusion 1b and an engagement claw 2b are formed on the other end of the container body 1 and the lid 2, and both are engaged when the lid 2 is rotated to overlap the container body 1. In this case, the closed state of the compact container A can be maintained.

[0009] The container body 1 has a substantially square concave portion 4 formed in the center thereof. The concave portion 4 is filled with a cosmetic K such as a foundation, for example. The cosmetic K contains a large amount of a solvent and has volatility.

[0010] The lid 2 has one surface constituting the external appearance of the compact container A, and has a hinge 2a and an engaging claw 2b of the lid 2 integrally formed with the outer plate 2A.
When the lid 2 is closed, the container body 1 is composed of the interior plate 2B facing the cosmetic K when the lid 2 is closed. That is, the upper surface 2c of the outer plate 2A is exposed as an appearance of the compact container A, and a dew condensation space S1 is formed between the lower surface 2d of the outer plate 2A and the upper surface 2e of the inner plate 2B.
A container space S0 is formed between the lower surface 2f of the base material and the surface of the cosmetic K.

A plurality of ventilation holes H1 are formed in the interior plate 2B in a matrix, and communicate the dew condensation space S1 and the container space S0. An upright piece 2h is formed on the upper surface of the peripheral edge 2g of the interior board 2B.

An annular gasket 5 is fitted around the periphery 2g of the interior plate 2B. The annular gasket 5 is formed of an elastic rubber material or the like, and is an L-shaped elastic body having a standing piece 5a and a flange 5b. The annular gasket 5 is provided in the recess 4 for holding the cosmetic K of the container body 1.
When the lid 2 is closed, it is pressed to the container body 1 on the outer peripheral edge of the concave portion 4 so as to surround the concave portion 4.

In the annular gasket 5, the peripheral edge 2g of the interior plate 2B presses down the flange 5b of the annular gasket 5, and the standing piece 2h of the interior plate 2B is ultrasonically welded to the lower surface 2b of the exterior plate 2A and bonded. By doing so, the structure is fixed to the lid 2.

Next, the function of the compact container A for preventing condensation and dripping will be described. When the compact container A is placed in a place where the temperature is high, solvents such as water and oil are volatilized from the cosmetic K in the container, and the volatilized solvent fills the compact container A kept airtight by the annular gasket 5. I do. Then, when the compact container A is cooled due to a decrease in air temperature or the like, the volatilized solvent comes into contact with a part of the lid 2 where the temperature has become low to form dew, thereby generating many water droplets.

At this time, the volatilized solvent enters not only the container space S0 but also the dew condensation space S1 through the vent hole H1. That is, the evaporated solvent is applied to the lower surface 2 of the exterior plate 2A.
d, the upper surface 2e of the interior board 2B and the lower surface 2f of the interior board 2B come into contact with each other to form dew condensation. For this reason, the compact container A has a condensation area about three times as large as that of a normal compact container in which the lid is a single plate.

For this reason, if the amount of the volatile solvent is constant, the amount of the solvent condensed on the lower surface 2f of the interior plate 2B, which causes the problem of condensation and dripping, is reduced to about 1/3 as compared with the conventional compact container. . The remaining 2/3 of the volatilized solvent is deposited on the lower surface 2d of the exterior plate 2A constituting the dew condensation space S1,
Condensation forms on the upper surface 2e of the interior plate 2B, and it is difficult for water droplets to fall on the cosmetic K from the condensation space. For this reason, the dew condensation falling on the surface of the cosmetic K can be relatively reduced, and the compact container hardly causes the dew drop.

In particular, since the upper surface 2c of the exterior plate 2A is in direct contact with the outside air and is most susceptible to a temperature change as compared with the interior plate 2B, the volatile solvent is removed from the lower surface 2 of the exterior plate 2A.
As a result, a large amount of solvent is condensed in the dew space S1, and the possibility of dew condensation in the container space S0 is reduced.

FIG. 3 is an explanatory view showing another example of the configuration of the ventilation holes provided in the interior plate. 6A and 6B are side sectional views of the interior board 2B. In FIG. 5A, a raised bank 6 is provided around the upper opening of the ventilation hole H2.
The structure is such that, even if the solvent is accumulated on the upper surface 2e, water droplets do not easily fall from the vent hole H2 onto the surface of the cosmetic K.

FIG. 2B shows that the inner surface 7 of the ventilation hole H3 is formed in a tapered shape having a small diameter in the upper part.
The opening on the upper surface 2e of B is made smaller so that the solvent on the interior board 2B is hardly dropped. In addition, in addition to these structural examples, a structure in which a drain such as a groove for returning the solvent reduced to liquid to the cosmetic K again may be provided in a part of the lid 2.

FIGS. 4 and 5 are perspective views of a compact container showing another example of the shape of the ventilation hole provided in the interior plate. The ventilation hole H4 shown in FIG.
4 are formed radially from the center of the interior board 2B. The ventilation holes H5 shown in FIG. 5 also have a slit shape, and are formed in the interior plate 2B so that a plurality of ventilation holes H5 are arranged in two rows. As described above, the design of the interior board can be changed by variously changing the shape and arrangement of the ventilation holes as shown in the examples.

The interior plate 12B is attached to the exterior plate 12A by fixing the annular projection 12h formed at the center of the upper surface 12e to the fixed projection 12g formed at the center of the lower surface 12d of the exterior plate 12A. ing. Due to the height of the annular protrusion 12h and the fixed protrusion 12g, a space is generated between the outer plate 12A and the inner plate 12B, and a dew space S1 is formed here. Further, a ventilation hole H6 is formed at the periphery of the interior plate 12B between the interior plate 12B and the exterior plate 12A, and the ventilation hole H6 is formed between the dew condensation space S1 and the container space S1.
0 is communicated.

An annular gasket 15 is fixed to the outer plate 12A so as to surround the inner plate 12B. This annular gasket 15 is an annular body slightly larger than the concave portion 4 of the container body 1 that holds the cosmetic K, and when the lid 12 is closed,
It is press-fitted to the container main body 1 on the outer peripheral edge of the concave portion 4 so as to surround the concave portion 4 to keep the container space S0 and the dew condensation space S1 airtight.

According to the compact container B of the second embodiment configured as described above, the ventilation holes H6 are formed around the interior plate 12B.
