Abstract

PROBLEM TO BE SOLVED: To improve the impact resistance intensity of a product by improving ventilation of air included in powder, especially air at the bottom of the powder, in solid powder cosmetic in which press pressure never makes difference by forming the bottom of a container in the same shape simulating the stereoscopic surface shape of the cosmetic so as to equalize the thickness of the cosmetic to be replenished and formed. SOLUTION: The container 1 for being directly filled with the powder cosmetic 2 to press-mold and solidify it has many small perforations 4 for ventilating air at the bottom surface of the container 1 to exhaust air in the bottom of the cosmetic.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder cosmetic container which is directly filled with a powder cosmetic, pressed and solidified, and in particular, the surface of the filled cosmetic is formed into a three-dimensional shape rather than a flat surface. A solid powder cosmetic container.

[0002]

2. Description of the Related Art Conventionally, there has been known a powder cosmetic which is directly filled with a powder cosmetic and then pressed to be solidified, wherein the surface of the cosmetic is formed into a three-dimensional shape instead of a flat surface. is there. Solid powder cosmetics molded into a three-dimensional surface have different impact strengths due to the thickness of the cosmetics when pressed compared to those molded with a flat surface, so the impact strength of the product is small and Cracks, etc.,
There was a disadvantage that it was easily broken.

[0003] In order to solve the drawbacks of the solid powder cosmetic whose surface is formed into a three-dimensional shape, the applicant of the present invention has disclosed a structure of a container as disclosed in Japanese Utility Model Laid-Open No. 7-20109. Suggested container. In this container, the bottom of the container is formed in the same shape following the three-dimensional surface shape of the cosmetic material, so that the thickness of the cosmetic material to be filled and molded is uniform, so that there is no difference in press pressure. It is characterized by: However, even in such a container structure, it was difficult to sufficiently remove air contained in the powder at the time of pressing. In particular, the air in the powder near the bottom of the container hardly escaped, making it impossible to obtain a sufficient drop impact strength of the product. For this reason, there has been a problem that cracks and breakage easily occur in the product.

[0004]

According to the present invention, the bottom of the container is formed in the same shape following the three-dimensional surface shape of the cosmetic, and the thickness of the filled and molded cosmetic is made uniform, and the pressing pressure is reduced. It is an object of the present invention to improve the impact resistance of a product in a solid powder cosmetic in which no difference is caused between the powder and the air contained in the powder, particularly the air at the bottom of the powder.

[0005]

Means for Solving the Problems The means adopted by the present invention to solve the above-mentioned problem is a container for directly filling and press-molding and solidifying powder cosmetics, and the air vent is provided on the bottom surface of the container. A large number of small holes for improving the air discharge from the bottom of the cosmetic.

A container for directly filling powder cosmetics and pressing the surface into a three-dimensional shape to be solidified, wherein the inner bottom surface of the container is formed in the same shape following the three-dimensional surface shape of the powder cosmetics. In addition, a large number of small holes for venting air are drilled in the bottom surface of the container, so that the air at the bottom of the cosmetic is discharged well.

It is characterized in that an air suction action is applied to the bottom of the container.

[0008] The present invention is characterized in that the peripheral edge of the container bottom is formed in a flat surface with a slight width.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below. Referring to the drawings, (1) is a dish-shaped cosmetic container having an open top according to the present invention, which is directly filled with powder cosmetic (2), press-molded and solidified. The illustrated container has a diameter of 100 mm and a depth of about 25
Although it has a relatively large dimension of mm, it may be a small cosmetic container called a so-called medium dish mounted in a compact container, and the size, shape, and use of the container are not particularly limited. The illustrated container is made of plastic, but is not limited to this, and may be made of metal such as aluminum or iron, or other materials.

[0010] In the container (1), the filled powder cosmetic (2) is formed into a three-dimensional surface shape protruding upward in an arc at the center as shown in the figure. Such a three-dimensional surface shape is adopted in order to improve the design of the product and improve the commercial value. The bottom (3) of the container (1) is a powder cosmetic
The same three-dimensional shape is formed following the three-dimensional surface shape of (2). As a result, the height between the bottom surface in the container and the surface of the powder cosmetic can be the same in the entire cosmetic, so that the powder cosmetic (2) has a uniform pressing pressure and a uniform density throughout the entire cosmetic. It can be compressed and can prevent a decrease in impact strength due to a difference in density. The press mold (6) for press molding has a large number of pores, and air contained in the powder cosmetic is sucked and removed from the pores during pressing. It is beneficial to apply a cloth or paper to the surface of the press mold to prevent the pores from being plugged with cosmetic powder.

[0011] The air collected on the bottom surface of the container can be removed from the surface of the powder cosmetic by using a press mold having such air suction pores or a cloth or paper for preventing the pores from being blocked. Was extremely difficult. For this reason, there was a problem that the bottom portion of the powder cosmetic was in a state of containing air and the impact resistance was reduced. Therefore, the present invention provides a container (1) having a bottom surface.
A large number of small holes (4) having a diameter of about 1 mm are formed in (3), and air near the bottom of the cosmetic is discharged from the small holes (4) during pressing. If the air is not sufficiently discharged only by the pressing force at the time of pressing, the air may be suctioned from the bottom of the container to positively remove the air. Further, in order to make it easier to remove air from the bottom, it is also effective to form the peripheral edge of the container bottom on a flat surface (5) having a width of about 1 mm as shown in FIG.

[0012]

According to the present invention, the filled powder cosmetic can be pressed at a uniform density, and the air contained in the cosmetic can be effectively removed. In particular, since it is possible to efficiently remove the air at the bottom of the cosmetic where removal of air is difficult, it is possible to improve the impact resistance of the cosmetic,
The drop resistance of the product is increased, and the occurrence of cracks and breakage can be suppressed.
