Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. It should be noted that description of configurations that can be appropriately performed by those skilled in the art will be omitted, and only the basic configuration of the present invention will be described.

<First embodiment>
As shown in FIG. 1, the cosmetics container 1 has a lid 10 and a container body 20. As shown in FIG. 2, the container body 20 has a hollow structure, and cosmetics are stored in the space. As shown in FIG. 3, the lid 10 also has a hollow structure. In this specification, the direction connecting the lid 10 and the container body 20 is referred to as "up-down direction", the direction of the lid 10 is referred to as "upward", and the direction of the container body 20 is referred to as "downward".

As shown in FIGS. 2 and 5, the container body 20 is configured by integrally forming a body portion 22 that constitutes the basic structure of the container body 20 and an inner surface portion 24 that constitutes an inner surface. The body portion 22 is arranged outside the inner surface portion 24 while being in contact with the inner surface portion 24. The main body 22 is formed by injection molding a resin. As the resin forming the main body portion 22, for example, a polyolefin resin such as polypropylene, a polystyrene resin, or a polyester resin can be used. In addition, in the present embodiment, the main body 22 also has a structure that constitutes the outer surface of the container body 20, but unlike the present embodiment, the outer surface of the container body 20 may be formed separately.

The inner surface portion 24 is formed by mixing a large number of copper fine particles and a resin, injection-molding an appropriate coupling material such as a silane coupling material, and other additives as necessary. As the type of resin forming the inner surface portion 24, the same resin as that of the main body portion 22 may be adopted, or a different resin may be adopted.

The body 22 and the inner surface 24 are integrally formed. Although an appropriate manufacturing method can be used for integrally forming, for example, a molding method such as insert molding, in-mold molding, or two-color molding is used.

As shown in FIGS. 2 and 4, the main body portion 22 is composed of a base portion 22a and a connecting portion 22b. A male screw portion 22c is formed on the connecting portion 22b. As shown in FIG. 3, a female screw portion 10c is formed on the inner surface 10b of the lid 10. When the male screw portion 22c of the connection portion 22b engages with the female screw portion 10c formed on the inner surface of the lid body 10, the lid body 10 and the container body 20 are detachably engaged.

FIG. 6 is a schematic plan view of the container body 20 of FIG. 5 viewed from the arrow Z1 direction. FIG. 7 is a schematic sectional view of the container body 20 shown in FIG. 6 taken along the line AA. As shown in FIG. 7, the thickness W1 of the base portion 22a of the main body portion 22 is larger than the thickness W2 of the inner surface portion 24. In other words, the thickness W2 of the inner surface portion 24 is smaller than the thickness W1 of the main body portion 22.

The ratio C (W2/W1) of the thickness W2 of the inner surface portion 24 to the thickness W1 of the body portion 22 is defined to be 0.001 or more and 0.050 or less, and preferably 0.002 or more and 0.008 or less. Stipulated in.

For example, the thickness W1 of the main body portion 22 is 3 millimeters (mm), the thickness W2 of the inner surface portion 24 is 20 micrometers (μm), and the ratio C (W2/W1) is 0.007. The inner surface portion 24 is configured as a sterilization portion that reduces bacteria. On the other hand, the main body portion 22 is configured as a non-sterile portion that does not have the effect of reducing bacteria.

FIG. 9 is an enlarged conceptual view showing a part B1 of the inner surface portion 24 shown in FIG. The inner surface portion 24 is formed such that copper fine particles 28 are dispersed in the resin and the fine particles 28 are covered with the resin 26. Specifically, the inner surface portion 24 is formed by dispersing a large number of copper fine particles 28 in the resin 26. The fine particles 28 are not exposed on the surface of the inner surface portion 24 and are covered with the resin 26. Copper is an example of a metal having antibacterial properties. The antibacterial metal is not limited to copper, but may be silver or zinc, for example. In this specification, "copper" shall include copper and copper oxide.

The predetermined range of the thickness W2 of the inner surface portion 24 is defined in relation to the size of the fine particles 28. As the size of the fine particles 28, for example, the maximum value (d50) of the particle size distribution of the fine particles is used. The diameter L1 corresponding to d50 is the size of the fine particles 28. The definition of the "diameter" of the diameter L1 is a sphere equivalent diameter. The diameter L1 is measured using, for example, a laser diffraction type particle size distribution measuring device. Note that, unlike the present embodiment, the diameter L1 may be the average particle diameter. Note that, since FIG. 9 is a conceptual diagram, for convenience of description, only the fine particles 28 having a single diameter L1 are shown, but in reality, the inner surface portion 24 has a predetermined maximum value of the diameter L1. Particle groups having a particle size distribution (typically normal distribution) are dispersed.

The diameter L1 of the fine particles 28 is defined in a predetermined range, for example, 10 nanometers (nm) or more and less than 100 nanometers, preferably 10 nanometers or more and less than 80 nanometers, and more preferably 10 nanometers or more. It is not less than nanometer and not more than 40 nanometer, more preferably not less than 10 nanometer and not more than 20 nanometer.

The shape of the fine particles 28 is, for example, spherical. As the fine particles 28, for example, copper particles of “copper nanoparticles SFCP series” manufactured by Fukuda Metal Foil & Powder Co., Ltd. (20, Nishinoyama Nakashinmachi, Yamashina-ku, Kyoto) can be used. Alternatively, as the fine particles 28, cuprous oxide particles having a primary particle diameter of about 50 nanometers (nm), which are manufactured by Furukawa Chemicals Co., Ltd. (3-7-196, Ono, Nishiyodogawa-ku, Osaka-shi, Osaka) are used. Good.

The thickness W2 of the inner surface portion 24 is larger than the diameter L1 of the fine particles 28, and further larger than the fine particles 28 having the maximum particle diameter in the particle size distribution. As a result, the fine particles 28 can be reliably covered with the resin 26, and the content of the fine particles 28 in the inner surface portion 24 can be ensured within a predetermined range. In the present embodiment, the diameter L1 is 50 nanometers (nm). In the present embodiment, the predetermined range of the content of the fine particles 28 in the inner surface portion 24 is 20 wt% (wt%) or more and 75 wt% or less, and desirably 40 wt% (wt%) or more and 75 wt% or less. Yes, and more preferably, it is 60 weight percent or more and 75 weight percent or less. In the present embodiment, the content of the fine particles 28 is 65 weight percent. ‥

The thickness W2 of the inner surface portion 24 is formed in a predetermined range of thickness defined in relation to the size of the fine particles 28, as described above. If the thickness W2 is too large, the effect of reducing the bacteria of the fine particles 28 on the side in contact with the main body 22 cannot be fully utilized. On the other hand, if the thickness W2 is too small, it is not possible to sufficiently fill the fine particles 28 for achieving the effect of reducing bacteria. Therefore, the thickness W2 is defined within a predetermined range in relation to the size of the fine particles 28.

In this specification, the ratio B of W2 to the diameter L1 (W2/L1) is referred to as "diameter ratio B". The relationship between the thickness W2 and the diameter L1 is shown as the numerical range of the diameter ratio B.

The diameter ratio B is defined as a range in which the effect of reducing the bacteria by the fine particles 28 can be appropriately utilized. For example, as the diameter L1 becomes smaller, the specific surface area of each individual fine particle 28 becomes larger, and the total surface area of the fine particle group as an aggregate of a large number of fine particles 28 becomes large, so that the surface area for outflow of copper ions becomes large. growing. Therefore, the smaller the diameter L1, the smaller the diameter ratio B may be.

The diameter ratio B is 100 or more and 10000 or less, preferably 100 or more and 5000 or less, more preferably 100 or more and 1000 or less, and more preferably 100 or more and 500 or less. The thickness W2 is defined in the diameter ratio B within the above numerical range with respect to the specific diameter L1. In this embodiment, the diameter L1 of the fine particles is 50 nanometers, the thickness W2 is 20 micrometers, and the diameter ratio B is 400.

As shown in FIG. 10, when the cosmetic 100 is stored in the container body 20, copper ions are released from the copper fine particles 28 forming the inner surface portion 24 to remove the resin 26 as shown by an arrow X1 in FIGS. 11 and 12. It passes through and contacts the cosmetics 100, acts on the bacteria in the cosmetics 100, and reduces the bacteria.

The copper fine particles 28 have a function of reducing bacteria even if they are not in direct contact with the cosmetic 100. This is different from the present invention in the technical field and completely different in configuration, but is described in, for example, Japanese Patent No. 4175486. This is also confirmed by the experimental results shown in FIG. For example, FIG. 13 shows an experimental result by an experiment by Professor Sasai of Kitasato University. As shown in FIG. 13, a cosmetic container made of a resin containing copper fine particles, in which the copper fine particles were not exposed, had a viable cell count of about 100,000 cfu/4 cm ² initially, but after 120 minutes (miniute). Has disappeared. Note that "cfu" means "Colony forming unit".

Since the resin 26 is in contact with the cosmetic 100, and the fine particles 28 are not in contact with the cosmetic 100, they do not react with the components of the cosmetic 100. That is, by disposing the resin 26 between the fine copper particles 28 and the cosmetic 100, it is possible to reduce bacteria without denaturing the cosmetic 100. In addition, the preservative that is usually added to the cosmetic 100 may not be added. Alternatively, the amount of preservative added can be reduced.

<Second embodiment>
Next, a second embodiment will be described with reference to FIG. Descriptions of matters common to the first embodiment will be omitted, and different points will be mainly described.

As shown in FIG. 14, the side surface of the inner surface portion 24A of the container body 20A of the second embodiment is formed as an uneven surface having a plurality of convex portions and concave portions. This makes it possible to increase the area in which the inner surface portion 24A contacts the cosmetic 100 as compared with the case where the inner surface portion 24A is a curved surface having no unevenness.

The thickness W2 of the inner surface portion 24A is the same as in the first embodiment. That is, the inner side surface of the main body portion 22A is also formed as an uneven surface, and the inner surface portion 24A is integrally formed with the inner side surface of the main body portion 22A.

Different from the present embodiment, both the side surface and the bottom surface of the inner surface portion 24A may be formed as an uneven surface having a plurality of convex portions and concave portions, or only the bottom surface is formed as such an uneven surface. May be.

<Third embodiment>
Next, a third embodiment will be described with reference to FIG. Descriptions of matters common to the first embodiment will be omitted, and different points will be mainly described.

The inner surface portion 24B of the container body 20B of the cosmetic container according to the third embodiment is arranged only on the side surface. That is, the main body 22 has a side surface and a bottom surface, of which the sterilization layer is arranged only on the side surface. Unlike the container body 20B of FIG. 15, if the container body has an elongated shape with a small bottom surface, the bacteria can be effectively reduced by disposing the inner surface portion 24B only on the side surface.

<Fourth Embodiment>
Next, a fourth embodiment will be described with reference to FIG. Descriptions of matters common to the first embodiment will be omitted, and different points will be mainly described.

The inner surface portion 24C of the container body 20C of the cosmetic container according to the fourth embodiment is arranged only on the bottom surface. That is, the main body 22 has a side surface and a bottom surface, of which the sterilization layer is arranged only on the bottom surface. Unlike the container body 20C in FIG. 16, if the container body has a smaller depth and a flatter shape, the bacteria can be effectively reduced by disposing the inner surface portion 24C only on the bottom surface. ..
