Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dish-shaped container for filling cosmetics, and more particularly to improving the jointability between the cosmetic and the inner peripheral surface of the container. Related to a dish-shaped container. 2. Description of the Related Art Conventionally, a dish-shaped container called a medium dish is exchangeably housed in an exterior container such as a compact container, and the dish-shaped container is filled with various cosmetics for use. Doing so is known. [0003] Since the depth of the inner plate is smaller than its inner diameter, the filled cosmetic material shrinks in the radial direction, the cosmetic material is separated from the inner peripheral side surface of the container, and a gap is formed, resulting in poor appearance. In addition, there is a problem that the cosmetic is rotated or dropped when the cosmetic is taken with a puff or the like. Particularly, in the case of cosmetics containing volatile components, since the cosmetics largely shrink due to volatilization of the volatile components, a phenomenon in which the cosmetics are separated from the inner peripheral side surface of the container is remarkable. In order to solve such a problem, a rib is conventionally projected on the inner peripheral side surface or the bottom surface, but it has not been able to sufficiently solve the problem. [0005] The present invention enhances the adhesion between the filled cosmetic and the inner peripheral surface of the container, prevents the cosmetic from shrinking in the radial direction, and shrinks vertically. Like so
It is intended to prevent the cosmetic from coming off the inner peripheral side of the container. [0006] In order to solve the above-mentioned problems, a means adopted by the present invention is to provide a dish-shaped container (1) having an open upper surface for filling and holding a cosmetic containing a volatile component . Inner side
In addition, a rib (3) projecting inward is
Formed and hexagonal with rectangular cross section on the inner peripheral side and bottom
Filled makeup that forms a shape or irregular continuous pattern (5)
To increase the contact area between the material (2) and the container (1)
By increasing the penetration of cosmetics into cosmetics,
The material (2) is brought into close contact with the inner peripheral side and bottom of the container (1),
Prevent radial shrinkage of cosmetics and shrink vertically
It is characterized by doing so. [0007] The means for improving the adhesion between the cosmetic applied to at least the inner peripheral surface of the container and the container improves the adhesiveness between the cosmetic and the inner peripheral surface of the container. The shrinkage of the material acts in the depth direction of the container and prevents the cosmetic material from shrinking in the inner diameter direction, thereby preventing the cosmetic material from separating from the inner peripheral side surface of the container. According to the present invention, the filled cosmetic does not come away from the inner peripheral side of the container, so that the cosmetic is good in appearance, and the cosmetic rotates in the container during use. There is no danger of dropping or falling off. Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Referring to FIG. 1, (1) is a resin or metal dish-shaped container having an open upper surface, which is called an inner plate, and is filled with a cosmetic (2). A rib (3) protruding inward is formed on the inner peripheral side surface of the dish-shaped container (1) so as to surround in an annular shape, and a streak-like rib (4) extending toward the center is formed on the bottom surface. It protrudes toward. Such a dish-shaped container (1)
When the filled cosmetic (2) is dried and solidified by volatilization of a volatile component, volatilization of a solvent, or the like, the cosmetic (2) shrinks in the inner diameter direction as shown in FIG. There was a drawback that 1) came away from the inner peripheral side surface. According to the present invention, as shown in FIG. 1, the cosmetic (2) is provided with a means for improving the adhesion to the cosmetic (2) on the inner peripheral surface of the dish-shaped container (1). The contraction direction is the vertical direction, and the cosmetic (2) is prevented from separating from the inner peripheral side surface of the container (1). Means for improving the adhesion of the cosmetic (2) include a concavo-convex pattern formed on the inner peripheral surface of the container (1) by pressing or the like, a rough surface formed by blasting or the like, paper, cloth or nonwoven fabric. , The application of an adhesive, the application of a sheet of resin or paper or the like having irregularities, the application of a sheet of resin or paper or the like with holes formed therein, and the like. Further, an adhesive may be further applied to the surface of paper, cloth, nonwoven fabric, resin or paper sheet adhered to the inner peripheral surface of the container. Further, these means are applied to at least the inner peripheral side surface of the container, but may be applied to the entire inner surface including the bottom surface. FIG. 3 is an enlarged view of the portion A of the container (1) on which the concavo-convex pattern (5) is formed by press working or other methods.
The relief pattern (5) preferably has a rectangular cross section. Due to the uneven pattern, the contact area between the cosmetic (2) and the container (1) increases,
In addition, the rectangular cross section increases the biting force into the cosmetic. Further, since the cosmetic also has a rectangular cross section, the structural strength is increased, the shape holding force is increased, and the adhesion is increased. The planar shape of the concavo-convex pattern (5) formed by the press working is not particularly limited, and hexagonal or rhombic patterns shown in FIGS. 8 and 9 or other square patterns or circular patterns may be aligned, but are shown in FIGS. Such an irregular pattern may be used. The depth of the uneven pattern is 50-100μ
The degree is preferred. The patterns in FIGS. 8 and 10 are 70 μ deep. FIG. 4 is a cross section of a rough surface (6) formed by blasting or the like. The rough surface (6) is roughened by using a blast having a large particle size because the effect of improving the adhesion is not sufficient if it is minute. FIG. 5 is a cross section in which a paper, a fabric or a non-woven fabric (7) is stuck, and the filled cosmetic (2) penetrates the paper, the fabric or the non-woven fabric and bonds with the fiber to increase the adhesion. FIG. 6 is a diagram in which a resin or paper sheet (8) having irregularities is attached, and FIG. 7 is a diagram in which a resin or paper sheet (9) having holes is adhered. Also in this case, there is an effect of improving the adhesion as in the case of an uneven pattern or a rough surface formed by pressing or breasting. One effective means is to apply an adhesive to improve the adhesion between the inner peripheral surface of the container and the cosmetic.
The adhesive is a hot-melt adhesive whose adhesive force is activated by heat because the cosmetic to be filled is heated, and chemically reacts with the cosmetic or gives a physical change. A material with no such material is selected. As the hot melt adhesive, for example, an olefin-based or polyester-based adhesive is suitable. Further, the adhesive may be used alone, but may be applied to the surface of the above-mentioned uneven pattern or rough surface (5) (6), paper, fabric or non-woven fabric (7) or sheet (8) (9). And may be used together. Further, as shown in FIG.
A nonwoven fabric (7) or a perforated paper or resin sheet (9) is adhered to the inner peripheral surface of the container (1) via an adhesive (10).
A part of (10) may be leached from the surface or holes of paper, cloth, or non-woven fabric (7) to join with the filled cosmetic (2). The cosmetic (2) may be an emulsion type, a solid powder type or any other cosmetic, and is not particularly limited. Cosmetics containing volatile components, such as water and volatile silicone oils, were particularly effective because of the high shrinkage of the cosmetics due to volatilization of the volatile components.
