Description

No sterilization

The present invention relates to a sterilization member for reducing bacteria in cosmetics.

The cosmetic container must be able to store while maintaining the quality of cosmetics such as a foundation.

For this reason, an additive such as a preservative (such as parapene) or phenoxy ethanol having an antiseptic effect may be added to the cosmetic product. However, it is preferable not to use preservatives or additives. In this regard, a technique has been proposed for filling a cosmetic product in a small container with a sufficient capacity to fill a single use amount (for example, Patent Document 1).

Japanese Patent Registration No.4627562

When the amount of use per use is a small amount, if the cosmetic is filled in a small container with a capacity sufficient to fill the amount of use per time, a large number of containers are required. In addition, the amount of use per time may be different for different people, and even for the same person, since it may vary depending on the situation, an excess or shortage occurs in the amount of cosmetics in the container, and eventually, the cosmetics may become useless.

The present invention is based on the above, to provide a sterilization member capable of reducing bacteria in cosmetics.

The first invention is a sterilization member disposed inside a cosmetic container for storing cosmetics, wherein metal fine particles having an effect of reducing bacteria are dispersed in a resin, and the fine particles are configured not to be exposed to the surface of the sterilizing member, It is a sterilizing member in which the type of metal is defined according to the type of bacteria in question at a specific location inside the cosmetic container.

According to the configuration of the first invention, since the sterilizing member disposed inside the cosmetic container is constituted by dispersing metal fine particles having an effect of reducing bacteria in a resin, it has an effect of reducing bacteria. Further, since the fine particles are configured not to be exposed to the surface of the sterilizing member, a chemical reaction between the metal and the cosmetic component causes the cosmetic product to not be denatured. In addition, as described later, it has been confirmed by experiments that bacteria can be reduced even when the metal does not directly contact cosmetics. In addition, the inventors of the present invention have found that the types of bacteria that can be effectively reduced differ depending on the type of metal. The inventors of the present invention have found that, for example, a metal capable of effectively reducing aerobic bacteria and a metal capable of effectively reducing anaerobic bacteria exist. In addition, the inventors of the present invention determine the type of metal effective for reduction according to the type of bacteria expected to become a problem at a specific location inside the cosmetic container, and a technique of dispersing the determined metal fine particles in the sterilization unit ( Hereinafter, "selective variance") was devised. In this regard, according to the configuration of the first invention, since the type of metal constituting the sterilizing member is defined in accordance with the type of bacteria expected to become a problem at each location inside, selective dispersion can be realized.

In the second invention, in the configuration of the first invention, the sterilization member includes a plurality of types of the metal fine particles, and according to the type of bacteria in question at the specific position where the sterilization member is disposed, the metal It is a sterilization member in which the content of each of the metal fine particles with respect to the total content of the fine particles is defined.

The type of bacteria expected to be a problem at a specific location inside the cosmetic container cannot be said to be one type. The inventors of the present invention believe that the bacteria that are expected to become a problem at a specific location inside are not limited to one type, and that the types of bacteria that can exist relatively largely differ depending on the specific location. I found it. For example, at any position inside the cosmetic container, aerobic bacteria and anaerobic bacteria may be a problem, but aerobic bacteria are more than anaerobic bacteria on the upper side, and anaerobic bacteria are considered to be more than aerobic bacteria on the lower side. And, according to the plurality of types of bacteria that are expected to become a problem at a specific location, in order to effectively reduce each bacteria, a technique of mixing and dispersing a plurality of types of metal fine particles into the sterilization unit (hereinafter referred to as "load dispersion" Ha) devised. According to this point, according to the configuration of the second invention, the sterilization member contains a plurality of types of metal fine particles, and the content of each metal fine particle depends on the type of bacteria expected to be a problem at a specific location inside the cosmetic container. Because it is specified, load distribution can be realized. In addition, load distribution is a technique of the sub-concept of selective distribution.

In the third invention, in the configuration of the first invention or the second invention, the specific position of the cosmetic container includes an upper part located at a relatively upper side and a lower part located at a relatively lower side, and the upper The bacteria that cause a problem on the side are aerobic bacteria, and the bacteria that are assumed to be a problem on the lower side are anaerobic bacteria, and the sterilization member is, on the upper side, the metal fine particles having a property of effectively reducing the aerobic bacteria. It is a sterilization member configured to increase the content of the metal fine particles having a property of effectively reducing the anaerobic bacteria in the lower portion, and to increase the content.

According to the configuration of the third invention, at each location inside the cosmetic container, by determining the type of metal and increasing the content of the metal fine particles, each location is determined according to the type of bacteria expected to be a problem with a relatively high possibility of causing a problem. It is possible to effectively reduce bacteria that are expected to have a relatively high probability of becoming a problem.

In the fourth invention, in the configuration of the third invention, the sterilization member is composed of at least one member, and the portion or the member located below the sterilizing member is the above having a property of effectively reducing the aerobic bacteria. It is a sterilizing member configured such that the proportion of the content of the metal fine particles is relatively small, and the proportion of the content of the metal fine particles having the property of effectively reducing the anaerobic bacteria is relatively large.

In a state where the cosmetic product is stored in the container body, the higher the upper side of the container body, the higher the possibility that aerobic bacteria become a problem, and the lower the lower side the container body, the higher the possibility that the anaerobic bacteria become the problem. In this regard, according to the configuration of the fourth invention, the content of metal fine particles that can effectively reduce bacteria is regulated according to the possibility that aerobic bacteria and anaerobic bacteria become a problem, so that bacteria can be effectively reduced at each location. .

In the fifth invention, in any one of the first to fourth inventions, in the sterilization member, the metal fine particles are at a position on the side of the surface in contact with the cosmetic, rather than at a position opposite to the surface in contact with the cosmetic, , Contains more, is sterile.

The closer and disperse the metal fine particles to the surface in contact with the cosmetic, the greater the effect of reducing bacteria. According to this point and the configuration of the fifth invention, since the content of the metal fine particles increases as the position closer to the surface in contact with the cosmetics of the sterilization unit, the bacteria can be effectively reduced.

In the seventh invention, in the configuration of the sixth invention, the suction tube is composed of a wall body constituting a main wall of the through hole of the suction tube, and a surface layer portion covering the wall body, and the surface layer portion is the sterilization portion. It is a constructed, sterile member.

According to the configuration of the seventh invention, since the mechanical strength of the suction tube can be secured by the wall body, the surface layer does not need to be thickened to secure the mechanical strength, and can be formed with an effective thickness to reduce bacteria. .

Since the suction tube is fixed to the cosmetic container, and the lower tip opening is located near the bottom of the cosmetic container, when a cosmetic product is sucked from the cosmetic container by the suction tube, the cosmetic product is sucked from the lower part inside the cosmetic container. In addition, when the amount of cosmetics in the cosmetic container decreases, the cosmetics are located only near the bottom of the cosmetic container. In this regard, according to the configuration of the eighth invention, it is possible to reduce bacteria in the cosmetics by the fixing member, regardless of the amount of cosmetics stored in the cosmetic container.

The ninth invention is a sterilization member in the configuration of the eighth invention, wherein the fixing member is composed of a main body and a surface layer covering the main body, and the surface layer is composed of the sterilization unit.

And the second type of the non-fixed member has a specific gravity substantially the same as that of the cosmetic, and the content of the metal fine particles having a property of effectively reducing the aerobic bacteria has a property of effectively reducing the anaerobic bacteria. It is configured to be substantially the same as the content of the metal microparticles, and the third kind of the non-fixed member has a higher specific gravity than the cosmetic product, and the content of the metal microparticles having a property of effectively reducing the aerobic bacteria is the anaerobic. It is a sterilizing member that is configured to be reduced by the content of the metal fine particles having a property of effectively reducing bacteria.

As shown in Fig. 2, in the soft container 3 of the container body 1, the cosmetic 200 is stored. In this embodiment, the cosmetic product 200 in a liquid state is stored in the container body 1. A suction tube 8 is disposed inside the container body 1. The suction tube 8 is a cylindrical member, and the through hole S1 (refer FIG. 3) is formed. Cosmetic 200 passes through the through hole S1. The container body 1 is an example of a cosmetic container. The suction tube 8 is an example of a sterilization member, and is an example of a suction tube.

The container body 1 is configured by airtightly bonding a manual pump member 4 to the opening of the flexible container 3. A suction tube 8 is connected to the pump member 4. That is, the suction tube 8 is a configuration for suctioning the cosmetic product from the container body 1. The suction tube 8 reaches the vicinity of the bottom of the soft container 3 and is configured to have a length not in contact with the bottom. The length of the suction tube 8 is defined according to the length of the soft container 3 in the vertical direction. The length of the flexible container 3 in the vertical direction is, for example, 50 mm, and the length of the suction tube 8 is, for example, 40 mm.

The flexible container 3 is composed of, for example, a soft laminated sheet used for a retort pouch, and laminated using polyester (PET) on the outer layer, aluminum foil on the intermediate layer, and non-stretched polypropylene (CPP) on the inner layer. It is produced by processing. In the present embodiment, the flexible container 3 thermally welds the left and right ends of two vertically long laminated sheets. Further, a bottom sheet is welded to the bottom portion of the soft container 3 to form a gusset, and the container body 1 is configured to stand on its own at the time of sealing the cosmetic.

The pump member 4 is constituted by a known manual pump mechanism. The parts of the pump member 4 are constituted by injection-molding a resin such as polypropylene (PP), for example. Known pump mechanisms, for example, by arranging mechanisms such as two check valves or check valves vertically and pressurizing the head of the pump to discharge the liquid between the two valves, By returning the head to its original position, the liquid inside is sucked up between the valves.

In this embodiment, the user presses the pressurization unit 13 from above, thereby discharging the cosmetic product 200 from the discharge port 12 by a certain amount to the outside, and the pressurization unit 13 with a biasing member provided inside the pressurization unit 13 When) returns to its original position, the liquid cosmetic 200 in the soft container 3 is sucked from the suction tube 8 by a predetermined amount.

The pump member 4 is provided with a connection part for bonding to the opening of the flexible container 3. The flexible container 3 in the form of a bag is heat-sealed and hermetically bonded to this connection part. In addition, a flange 10 for fixing the container body 1 to the rigid container 6 described later is provided at this connection part.

As shown in Figs. 3 to 6, the suction tube 8 is constituted by wall portions 8a, 8b constituting the circumferential wall of the through hole S1. The wall portions 8a and 8b are entirely constituted by a sterilization portion that reduces bacteria. The vicinity of the lower end portion of the wall portion 8a and the vicinity of the upper end portion of the wall portion 8b overlap. The suction tube 8 is composed entirely of a sterilization unit. The inner diameter of the upper wall portion 8a is the same as or slightly smaller than the outer shape of the lower wall portion 8b. By inserting the wall portion 8b inside the wall portion 8a, the wall portion 8a and the wall portion 8b can be integrated.

The wall portions 8a and 8b are formed by dispersing metal fine particles having an effect of reducing bacteria in a resin. The fine particles are configured not to be exposed to the surfaces of the wall portions 8a and 8b.

On the upper side, which is a specific position inside the container body 1, there is a high possibility that aerobic bacteria are mainly a problem. A wall portion 8a is disposed on the upper side. On the relatively lower side, it is likely that mainly anaerobic bacteria will be a problem. On the lower side, the wall portion 8b is disposed. In the wall portions 8a and 8b, the type of metal is defined in accordance with the type of bacteria expected to become a problem at a specific location of the container body 1.

The wall portions 8a and 8b are tubes (pipes) made of elastically deformable material, and the material, diameter, and length are not limited. As the material for the wall portions 8a and 8b, for example, resins such as soft polyethylene, soft polypropylene, soft polyurethane, soft silicone, soft polyetheretherketone, and soft vinyl chloride can be used.

(8b) consists of redundancy. The wall portion 8a is an example of the upper portion, and the wall portion 8b is an example of the lower portion. In addition, the position at which the wall part 8a is arrange|positioned and the position at which the wall part 8b is arrange|positioned are an example of the specific position inside the container body 1.

7 is an enlarged conceptual diagram showing a cross section in the vertical direction of the portion A1 of the wall portion 8a of FIG. 3. As shown in FIG. 7, in the wall portion 8a, metal fine particles 28A having an effect of reducing bacteria are dispersed in the resin 26. The fine particles 28A are covered with the resin 26 and are configured not to be exposed to the surface of the wall portion 8a. A metal having an effect of reducing bacteria is a metal capable of effectively reducing aerobic bacteria, for example copper. In this specification, "copper" shall contain copper and copper oxide.

FIG. 8 is an enlarged conceptual diagram showing a cross section in the vertical direction of the portion A2 of the wall portion 8b of FIG. 3. As shown in Fig. 8, in the wall portion 8b, metal fine particles 28B having an effect of reducing bacteria are dispersed in the resin 26. The fine particles 28B are configured so that they are covered with the resin 26 and are not exposed to the surface of the wall portion 8b. A metal having an effect of reducing bacteria is a metal capable of effectively reducing anaerobic bacteria, for example silver. In this specification, "silver" shall contain silver and silver oxide.

The thickness W1 of the wall portions 8a and 8b is formed to have a thickness within a predetermined range defined by the relationship with the size of the external shape of the fine particles 28A and 28B. As the size of the external shape of the fine particles 28A and 28B, for example, the maximum value d50 of the particle size distribution of the fine particles is used. The diameter L1 corresponding to the maximum value d50 is taken as the size of the fine particles 28. The diameter L1 is defined as a diameter equivalent to a sphere. The diameter L1 is measured using, for example, a laser diffraction particle size distribution measuring device. Further, unlike the present embodiment, the diameter L1 may be an average particle diameter. 7 and 8 are conceptual diagrams, and for convenience of explanation, only a single diameter L1 fine particle 28A, 28B is displayed, but in reality, in the surface layer 8b, a predetermined maximum value d50 is used as the diameter L1. A group of particles with a particle size distribution (typically a normal distribution) is dispersed.

The diameter L1 of the fine particles 28A and 28B is defined in a predetermined range, for example, 10 nanometers (nm) or more and 100 nanometers or less, preferably 10 nanometers or more and 80 nanometers or less, and further Preferably, they are 10 nanometers or more and 40 nanometers or less, and even more preferably, they are 10 nanometers or more and 20 nanometers or less.

The shape of the fine particles 28A and 28B is, for example, a spherical shape. However, the external shape is not limited to the spherical shape. As the fine particles 28A, for example, copper particles of the "copper nanoparticles SFCP series" related to the production of Fukuda Metal Foil Powder Industrial Co., Ltd. (20 Nishinoyamanakatomicho, Yamashina-ku, Kyoto) can be used. Alternatively, as the fine particles (28A), copper oxide particles having a primary particle diameter of about 50 nanometers (nm) related to the manufacture of Koga Chemicals Co., Ltd. (No. 7 196, Ono Sanchome, Nishiyodogawa-ku, Osaka City, Osaka) were used. Also works.

As the fine particles 28B, for example, silver particles of "AG Nano powders" related to the production of DOWA Electronics Co., Ltd. (No. 14 1, Sotokanda Yonchome, Chiyoda-ku, Tokyo) can be used.

The thickness W1 of the wall portions 8a and 8b is larger than the diameter L1 of the fine particles 28A and 28B, and larger than the maximum particle diameter fine particles 28A and 28B in the particle size distribution. Thereby, all the fine particles 28A and 28B are surely covered with the resin 26, and the content of the fine particles 28A and 28B in the wall portions 8a and 8b can be ensured within a predetermined range. In this embodiment, the diameter L1 is, for example, 50 nanometers (nm). In this embodiment, the predetermined range of the total content of the fine particles 28A and 28B in the wall portions 8A and 8B is 20% by weight or more and 80% by weight or less, preferably 40% by weight (wt. %) or more and 75% by weight or less, more preferably 60% by weight or more and 75% by weight or less. In this embodiment, the content of the fine particles 28A and 29B is 65% by weight.

The thickness W1 of the wall portions 8a and 8b is formed to have a thickness within a predetermined range defined in relation to the size of the external shape of the fine particles 28A and 28B, as described above. If the thickness W1 is too large, the effect of reducing bacteria of the fine particles 28A and 28B located near the center of the wall portions 8a and 8b cannot be fully utilized. On the other hand, if the thickness W1 is too small, the fine particles 28A and 28B for giving the bacteria reduction effect cannot be sufficiently filled. For this reason, the thickness W1 is defined in a predetermined range in relation to the size of the fine particles 28A and 28B.

In this specification, the ratio B (W1/L1) of the thickness W1 to the diameter L1 is referred to as "diameter ratio B". The relationship between the thickness W1 and the diameter L1 is expressed as a numerical range of the diameter ratio B.

The diameter ratio B is defined as a range in which the effect of reducing bacteria due to the fine particles 28A and 28B can be suitably utilized. For example, as the diameter L1 decreases, the specific surface area of each of the fine particles 28A and 28B increases, and the sum of the surface areas of the fine particle group as an aggregate of a large number of fine particles increases, so that the surface area for the outflow of copper ions and silver ions It gets bigger. For this reason, the smaller the diameter L1 is, the smaller the diameter ratio B can be.

The diameter ratio B is, for example, 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 still more preferably 100 or more and 500 or less. For a specific diameter L1, in the diameter ratio B in the above numerical range, the thickness W1 is defined. In this embodiment, the diameter L1 of the fine particles is 50 nanometers, the thickness W1 is 20 micrometers, and the diameter ratio B is 400.

The method of forming the wall portion 8a is carried out by preparing a mixed powder obtained by dispersing a predetermined amount of copper fine particles 28A in a resin powder, and dissolving and molding the mixed powder by injection molding. The method of forming the wall portion 8b is carried out by preparing a mixed powder obtained by dispersing a predetermined amount of silver fine particles 28B in a resin powder, and dissolving and molding the mixed powder by injection molding.

When cosmetics are stored in the container body 1, copper ions are released from the copper fine particles 28A, and silver ions are released from the silver fine particles 28B, as indicated by arrows X1 and X2 in FIGS. 9 to 11. As a result, it passes through the resin 26, comes into contact with the cosmetics 200, acts on the bacteria in the cosmetics 200, and reduces the bacteria.

The microparticles 28A and 28B function to reduce bacteria even if they do not come into direct contact with the cosmetics 200. This is different from the present invention in the technical field, and the configuration is completely different, but is described in, for example, Patent No. 4175486. Moreover, this is also confirmed by the experimental result shown in FIG. For example, Fig. 12 is an experiment result of an experiment conducted by Professor Sasai of Kitazato University. As shown in Fig. 12, the number of viable bacteria that initially existed about 100, 000 cfu/4 cm ² in a container in which the copper fine particles were not exposed with a resin containing copper fine particles was eliminated after 120 minutes. In addition, "cfu" means "colony forming unit".

As described above, the wall portions 8a and 8 of the suction tube 8 are constituted by a sterilization portion. Since the suction tube 8 is a passage for the cosmetic product 200, its wall portions 8a and 8b are in contact with the cosmetic product 200. That is, by configuring the suction tube 8 as a sterilization unit, bacteria in the cosmetic 200 can be reliably reduced.

Further, the resin 26 is in contact with the cosmetic 200, and the fine particles 28A and 28B do not contact the cosmetic 200, and thus do not react with the components of the cosmetic 200. That is, by disposing the resin 26 between the fine particles 28A and 28B and the cosmetic 200, it is possible to reduce bacteria without denature the cosmetic 200. In addition, preservatives that are normally added to the cosmetic 200 may not be added. Alternatively, the amount of the preservative to be added can be reduced.

<How to assemble the container body (1)>

A method of assembling the cosmetic container 100 will be described with reference to FIGS. 13 to 15. First, the connection portion constituting the pump member 4 and the bag-shaped soft container 3 are hermetically bonded by heat welding. Next, a predetermined amount of the cosmetic product 200 in a liquid state is placed in the soft container 3. Then, a portion of the pump member 4 in which the pump mechanism is incorporated is fixed by a screw formed on the wall body of the pump member 4.

When the cosmetic product 200 is stored in the soft container 3, as shown in FIG. 14, the soft container 3 is placed inside the hard container 6. 15, by disposing the flange 10 of the container body 1 at the inlet edge of the hard container 6, and screwing the fixing ring 9 to the hard container 6, the hard container ( Fix the container body (1) against 6). The inner diameter of the fixing ring 9 is a size through which the pressing portion 13 of the pump member 4 of the container body 1 passes.

By providing a rigid container 6 that houses the container body 1 therein, only the container body 1 can be replaced. Accordingly, unnecessary disposal of the hard container 6 is eliminated, so that the manufacturing cost of the cosmetic composition can be lowered, and at the same time, the waste can be reduced.

Since the pressing portion 13 of the pump member 4 is arranged to extend outward from the hard container 6, it is not necessary to take out the container body 1 from the hard container 6 every time the cosmetic product is discharged.

When the cosmetics 200 are used up, the user purchases only the container body 1 in which the cosmetics 200 are stored. In this case, since there is no hard container 6, the user can purchase the cosmetics 200 at a lower price. After purchase, the user removes the fixing ring 9, removes the container body 1 that does not contain the cosmetics 200, and puts the purchased container body 1 in the hard container 6, and the fixing ring 9 ). In this way, the expensive hard container 6 can be reused and waste can be reduced.

The inventors of the present invention have found that the types of bacteria that can be effectively reduced differ depending on the type of metal. Specifically, it was found that the type of metal capable of effectively reducing aerobic bacteria and the type of metal capable of effectively reducing anaerobic bacteria are different. Then, the inventors of the present invention devised a technique ("selective dispersion") of determining the type of metal effective for reducing the metal according to the type of bacteria, and dispersing the metal fine particles in a sterilization unit. Regarding copper and silver, copper can effectively reduce aerobic bacteria, and silver can effectively reduce anaerobic bacteria. In addition, the type of bacteria is not limited to aerobic bacteria and anaerobic bacteria, and the type of metal according to the type of bacteria is not limited to metals that effectively reduce aerobic bacteria and metals that effectively reduce anaerobic bacteria. For example, in addition to aerobic bacteria and anaerobic bacteria, since microaerobic bacteria and breathable anaerobic bacteria exist, metals that effectively reduce them can be applied to the sterilization member. In addition, the kind of bacteria is not limited to the regulation in relation to oxygen.

When the cosmetic product 100 is stored in the cosmetic container 1, since the upper portion of the container body 20 is easily in contact with air, it is considered that aerobic bacteria are mainly a problem. On the other hand, since the lower part of the container body 20 is difficult to contact with air, it is considered that anaerobic bacteria are mainly a problem.

Aerobic bacteria are, for example, mold, Pseudomonas aeruginosa, normal mycobacterium, and Bacillus bacillus. Anaerobic bacteria are, for example, Welsh bacterium and botolimus bacterium. In the present embodiment, copper fine particles capable of effectively reducing aerobic bacteria are dispersed in the upper portion 8a, and silver fine particles capable of effectively reducing anaerobic bacteria are dispersed in the lower portion 8b. Thereby, depending on the position of the cosmetic container 1 in the container body 20 in the vertical direction, bacteria considered to be a problem can be effectively reduced.

In metal fine particles to be dispersed in resin, the specific surface area is important. In the case where the ease of handling is not considered in the actual production, the smaller the particle diameter is, the larger the specific surface area is, which is preferable during the reduction of bacteria. If the effect of reducing bacteria at the standard particle diameter is used as the reference effect, when the particle diameter is changed to a small one, the reference effect can be achieved even if the total amount of particles is reduced. For example, the standard particle diameter is set to the particle diameter φ1, and the smaller particle diameter is set to the particle diameter φ2. It is said that the reference effect can be achieved by setting the content of the metal particles having a particle diameter of φ1 per unit weight of the resin as the content Wg1. Then, if it is changed to the metal particle of particle diameter phi2, the reference effect can be achieved by the content Wg2 which is the content less than the content Wg1.

<2nd embodiment>

Next, a second embodiment will be described with reference to FIGS. 16 to 19. Descriptions of items in common with the first embodiment will be omitted, and different parts will be mainly described.

In the second embodiment, as shown in Figs. 16 and 17, the suction tube 8A is constituted by surface layer portions 8Ab1 and 8Ab2 covering the wall main body 8Aa. The wall body 8Aa is configured as a non-sterilized portion, and the surface layer portions 8Ab1 and 8Ab2 are configured as a sterilized portion. That is, a part of the suction tube 8A is configured as a sterilization part. The surface layer portion 8Ab1 constitutes the outer surface of the suction tube 8A, and the surface layer portion 8Ab2 constitutes the inner surface of the suction tube 8A. The surface layer portions 8Ab1 and 8Ab2 are collectively referred to as the surface layer portion 8Ab. The positions where the surface layer portions 8Ab1 and 8Ab2 exist are examples of specific positions inside the container body 1, respectively.

The wall body 8Aa is a tube (tube) made of elastically deformable material, and its material, diameter, and length are not limited. As the material of the wall body 8a, for example, a resin such as soft polyethylene, soft polypropylene, soft polyurethane, soft silicone, soft polyetheretherketone, and soft vinyl chloride can be used.

The surface layer portion 8Ab is formed by dispersing a metal having an effect of reducing bacteria in a resin. The resin constituting the wall main body 8Aa and the resin constituting the surface layer portion 8Ab may be the same type of resin or different types of resin.

The wall body 8Aa and the surface layer 8Ab are formed integrally. In order to form integrally, if it is extrusion molding, all employ an extrusion molding method. In the case of injection molding, a molding method such as insert molding, in-mold molding, or dichroic molding is used. The surface layer portion 8Ab is formed by adding an appropriate coupling material such as a silane coupling material, and other additives as necessary.

The wall main body 8Aa is formed with a predetermined thickness for securing the mechanical strength of the suction tube 8A. The predetermined thickness is, for example, 0.3 millimeters (mm) to 2.0 millimeters (mm). The inner diameter of the suction tube 8, that is, the diameter of the through hole S1, is, for example, 3.0 millimeters (mm) to 8.0 millimeters (mm).

Since the mechanical strength of the suction tube 8A is ensured by the wall body 8Aa, the surface layer portion 8Ab is formed to have a suitable thickness in order to reduce bacteria.

18 is an enlarged conceptual diagram showing a cross section in the vertical direction of a portion A3 of the surface layer portion 8Ab1 of FIG. 16. FIG. 19 is an enlarged conceptual diagram showing a cross section in the vertical direction of a portion A4 of the surface layer portion 8Ab2 in FIG. 16. 18 and 19, in the surface layer portions 8Ab1 and 8Ab2, metal fine particles 28A and 28B having an effect of reducing bacteria are dispersed in the resin 26. The fine particles 28A and 28B are covered with the resin 26 and are not exposed to the surfaces of the surface portions 8Ab1 and 8Ab2. Both the surface layer portion 8Ab1 on the outer surface side of the suction tube 8A and the surface layer portion 8Ab2 on the inner surface side are constituted by dispersing a plurality of types of metals in resin. The surface layer portions 8Ab1 and 8Ab2 have different contents of the respective metal fine particles.

The plural kinds of metals are copper and silver in this embodiment. The surface layer portions 8Ab1 and 8Ab2 all contain copper fine particles and silver fine particles, but the ratio Xcu of the content of the copper fine particles to the content of all the metal fine particles is different from the ratio Xag of the content of the silver fine particles to the contents of all the metal fine particles. In this embodiment, as in the first embodiment, the particle size distribution of the copper fine particles and the particle size distribution of the silver fine particles are substantially the same. For this reason, as the content, the weight of the copper fine particles and the weight of the silver fine particles are used per unit weight of the resin, respectively. That is, the ratio Xcu of the copper fine particles is the ratio Xcu = (weight of Cu)/(the weight of Au and Cu), and the ratio Xag of the silver fine particles is the ratio Xag = (weight of Ag)/(the weight of Au and Cu) to be. Moreover, since the specific gravity of copper and silver is different, unlike this embodiment, the content of copper and silver can be prescribed|regulated based on the specific gravity. For example, if the specific gravity of copper is 8.5 g/cm ³ and the specific gravity of silver is 10.5 g/cm ³ , when all metal fine particles are composed of 8.5 g of copper and 10.5 g of silver, the content of copper and silver will be the same. I can.

As shown in Fig. 18, in the surface layer portion 8Ab1, the content of the copper fine particles 28A is greater than that of the silver fine particles 28B. And, as shown in Fig. 19, in the surface layer portion 8Ab2, the content of the silver fine particles 28B is greater than the content of the copper fine particles 28A. That is, the ratio Xcu in the surface layer portion 8Ab1 is larger than the ratio Xcu in the surface layer portion 8Ab2. And the ratio Xag in the surface layer part 8Ab2 is larger than the ratio Xag in the surface layer part 8Ab1. In addition, in Figs. 18 and 19, the amount of content is expressed according to the amount of the number of fine particles 28A and 28B. This is the same in other provinces.

The method of configuring the surface layer portions 8Ab1 and 8Ab2 to have a predetermined ratio Xcu and Xag is, for example, preparing a mixed powder obtained by dispersing a predetermined amount of copper fine particles 28A and silver fine particles 28B in a resin powder. , By injection molding, by dissolving and molding the mixture. The manufacturing method of the surface layer portions 8Ab1 and 8Ab2 is not limited to the above-described method. For example, the surface layer portions 8Ab1 and 8Ab2 may connect a sheet (foil) in which the above-described metal is dispersed in a resin on the inner and outer surfaces of the wall body 8Aa, unlike the present embodiment. In addition, the surface layer portions 8Ab1 and 8Ab2 may be coated on the inner and outer surfaces of the wall body 8Aa by forming a coating agent using resin and the above-described metal.

The type of bacteria considered to be a problem at a specific location of the container body 1 cannot be said to be one type. According to the inventors of the present invention, at a specific location of the container body 1, there are a plurality of types of bacteria that are expected to become a problem, and, depending on the specific location, a specific type of bacteria that can exist relatively largely. Found something else.

And, according to the kind of plural kinds of bacteria that are expected to exist in a specific location, a technique of mixing and dispersing metal fine particles in the sterilization part for effectively reducing each of the bacteria was conceived ("load dispersion").

In this embodiment, aerobic bacteria and anaerobic bacteria may be a problem at the positions inside the container body 1 corresponding to the surface portions 8Ab1 and 8Ab2, but a relatively aerobic bacteria problem in the surface layer 8Ab1 Is large, and it is considered that the problem of anaerobic bacteria is relatively large in the surface layer portion 8Ab2. In this regard, since the content of the copper fine particles is relatively large in the surface layer portion 8Ab1 with respect to the content of all metal particles, and the content of the silver fine particles in the surface layer portion 8Ab2 is relatively large with respect to the content of all the metal particles, the container body 1 ), it is possible to effectively reduce each of the bacteria according to the plurality of types of bacteria that are expected to be present in a specific location.

<3rd embodiment>

Next, a third embodiment will be described with reference to FIGS. 20 to 23. Descriptions of items in common with the first and second embodiments will be omitted, and different parts will be mainly described.

20 is a schematic cross-sectional view of the cylindrical suction tube 8B in the vertical direction. 21 is a schematic cross-sectional view of the suction tube 8B cut in the horizontal direction. As shown in Figs. 20 and 21, the suction tube 8B of the third embodiment is constituted by a wall portion 8ba that partitions the through hole S1. The wall part 8ba is composed of a sterilized part.

The wall portion 8ba contains metal fine particles having a property of effectively reducing aerobic bacteria and metal fine particles having a property of effectively reducing anaerobic bacteria. Further, the wall portion 8ba is configured so that the higher the upper side, the higher the content of the metal microparticles having the property of effectively reducing aerobic bacteria, and the lower the lower side, the lower the content of the metal microparticles having the property of effectively reducing the aerobic bacteria. . Further, the wall portion 8ba is configured such that the content of the metal fine particles having a property of effectively reducing anaerobic bacteria increases from top to bottom.

As shown in Fig. 22, when the wall portion 8ba is divided into regions S1 to S5 from top to bottom, the content of the copper fine particles 28A decreases as the regions S1 to S5 decrease, and the silver fine particles 28B. The content of is increased. Conversely, as it goes from region S5 to S1, the content of the copper fine particles 28A increases, and the content of the silver fine particles 28B decreases.

In more detail, as shown in Fig. 23, if the distance from the lowest position of the tube 8B is defined as height, the higher the height, the larger the content ratio of the copper fine particles in all the metal particles. Conversely, the smaller the height, the larger the content ratio of the silver fine particles in all the metal particles. In order to configure the distribution of metal particles in the tube 8B in this way, for example, specific gravity is used. For example, in injection molding, it takes advantage of the fact that the specific gravity of copper is smaller than that of silver.

It is considered that the ratio of aerobic bacteria to all bacteria decreases and the ratio of anaerobic bacteria increases as it goes to the lower portion of the container body 1 in a state where the cosmetic product 200 is stored in the container body 1. According to this point and the present embodiment, it is possible to effectively reduce bacteria at each position inside the container body 1 according to the ratio of aerobic bacteria and anaerobic bacteria considered to be a problem.

<4th embodiment>

Next, a fourth embodiment will be described with reference to FIGS. 24 to 26. Descriptions of items in common with the first and second embodiments will be omitted, and different parts will be mainly described.

The suction tube 8C of the fourth embodiment is constituted by a body portion 8a and a surface layer portion 8Cb1 so as to be shown in FIGS. 24 and 25. The surface layer portion 8Cb1 is composed of a sterilized portion.

The surface layer portion 8Cb1 is constituted by dispersing metal fine particles 28A and 28B in the resin 26. Referring to Fig. 26, the surface layer portion 8Cb1 will be described. One side surface 8R of the surface layer portion 8Cb1 contacts the cosmetic product. The metal fine particles 28A and 28B are contained in a large amount at a position on the side of the surface 8R and at a position on the side of the opposite surface 8.

The closer and disperse the metal fine particles to the surface in contact with the cosmetic, the greater the effect of reducing bacteria. In this regard, according to the configuration of the present embodiment, since the metal fine particles are contained in a larger amount at the position on the side of the surface in contact with the cosmetic, compared to the position opposite to the surface in contact with the cosmetic, it is possible to effectively reduce bacteria. have.

The technique of distributing a large amount of metal fine particles by one side of the surface layer portion 8Cb1 is, for example, preparing a mixed powder obtained by dispersing a predetermined amount of copper fine particles 28A and silver fine particles 28B in a resin powder, and It is carried out by dissolving and molding the mixture by injection molding in a medium or magnetic field. Alternatively, it may be carried out by appropriately adjusting the blending of the mixed powder.

Unlike the present embodiment, the surface layer portion 8Cb1 can be configured to contain one type of metal fine particles. For example, the surface layer portion 8Cb1 can be configured to contain only either of the copper fine particles 28A or the silver fine particles 28B.

<Fifth embodiment>

Next, a fifth embodiment will be described with reference to FIG. 27. Descriptions of items in common with the first to fourth embodiments are omitted, and different parts will be mainly described.

27 is a schematic cross-sectional view in the horizontal direction of the suction tube 8D of the fifth embodiment. The suction tube 8D is constituted by a body portion 8Da and a surface layer portion 8Db. The surface of the surface layer portion 8Db is configured as an uneven surface having a concave portion and a convex portion, as shown in FIG. 27. The surface layer portion 8Db is composed of a sterilized portion. Specifically, the inner surface of the body portion 8Da in contact with the through hole S1 is a curved surface without irregularities, and the outer surface is formed as an irregular surface having a concave portion and a convex portion. The surface layer portion 8Db is formed to have a uniform thickness along the uneven surface of the body portion 8Da.

In the suction tube 8D, since the surface area of the sterilization portion is large compared to the case where the surface of the sterilization portion is formed on a flat surface without irregularities, it is possible to more effectively reduce bacteria.

<6th embodiment>

Next, a sixth embodiment will be described with reference to FIGS. 28 to 33. Descriptions of items in common with the first to fifth embodiments will be omitted, and different parts will be mainly described.

In the sixth embodiment, as shown in FIGS. 28 and 29, the fixing members 2A and 2B are fixed to the suction tube 8. The fixing member 2A is fixed to a relatively upper portion of the suction tube 8. The fixing member 2B is fixed near the lower end of the suction tube 8. In the present specification, "fixed in the vicinity of the lower end" means that the position of the lower end of the fixing member 2B is disposed at a position within a predetermined distance range from the lower end of the suction tube 8. The predetermined distance is, for example, 1 millimeter (mm) or more and 5 millimeters (mm) or less. The fixing members 2A and 2B are arranged in a manner that does not block the through hole of the suction tube 8. The fixing members 2A and 2B are constituted by a sterilization unit. Further, the portion to which the fixing member 2B is fixed may be a lower end of the suction tube 8. The fixing members 2A and 2B are collectively referred to as "fixing member 2".

30 and 31, the fixing member 2 is a cylindrical member. The fixing member 2 has a through hole S2. The main wall portion 2Ga of the fixing member 2 is constituted by a sterilization portion.

32 and 33 are enlarged conceptual diagrams showing a portion A7 of the surface layer portion 2Ga of FIG. 30. FIG. 32 shows the surface layer portion 2Ga of the fixing member 2A, and FIG. 33 shows the surface layer portion 2Ga of the fixing member 2B.

As shown in Fig. 32, in the fixing member 2A, metal fine particles 28A having an effect of reducing bacteria are dispersed in the resin 26. The fine particles 28A are configured so that they are covered with the resin 26 and are not exposed to the surface of the fixing member 2A. A metal having an effect of reducing bacteria is a metal capable of effectively reducing aerobic bacteria, for example copper.

As shown in Fig. 33, in the fixing member 2B, metal fine particles 28B having an effect of reducing bacteria are dispersed in the resin 26. The fine particles 28B are configured so that they are covered by the resin 26 and are not exposed to the surface of the fixing member 2B. A metal having an effect of reducing bacteria is a metal capable of effectively reducing anaerobic bacteria, for example silver.

In the case where the cosmetic product 100 is stored in the cosmetic container 1, since the upper portion of the container body 20 is easily in contact with air, it is expected that mainly aerobic bacteria will be a problem. On the other hand, since the lower part of the container body 20 is difficult to contact with air, it is expected that anaerobic bacteria will be a problem mainly.

In this embodiment, in the fixing member 2A disposed on the upper side, copper fine particles capable of effectively reducing aerobic bacteria are dispersed, and in the fixing member 2B disposed on the lower side, the anaerobic bacteria can be effectively reduced. Silver fine particles are dispersed. Thereby, depending on the position of the cosmetic container 1 in the container body 20 in the vertical direction, it is possible to effectively reduce bacteria expected to become a problem.

<7th embodiment>

Next, a seventh embodiment will be described with reference to ratio 35 in FIG. 34. Descriptions of matters in common with the sixth embodiment will be omitted, and different parts will be mainly described.

As shown in Figs. 34 and 35, both of the fixing members 2C and 2D are configured so that a plurality of types of metals are dispersed in the resin. The fixing members 2C and 2D have different contents of each metal fine particle. The fixing member 2C is arranged above the suction tube 8, and the fixing member 2D is arranged near the lower end of the suction tube 8.

Both of the fixing members 2C and 2D contain copper fine particles and silver fine particles, but the ratio Xcu of the content of the copper fine particles to the content of all the metal fine particles and the ratio of the content of silver fine particles Xag to the content of all the metal fine particles are different.

As shown in Fig. 34, in the fixing member 2C, the content of the copper fine particles 28A is greater than the content of the silver fine particles 28B. And, as shown in Fig. 35, in the fixing member 2D, the content of the silver fine particles 28B is larger than the content of the copper fine particles 28A. That is, the ratio Xcu in the fixing member 2C is larger than the ratio Xcu in the fixing member 2D. And the ratio Xag in the fixing member 2D is larger than the ratio Xag in the fixing member 2C.

The method of realizing the predetermined ratios Xcu and Xag is, for example, preparing a mixed powder obtained by dispersing a predetermined amount of copper fine particles 28A and silver fine particles 28B in a resin powder, and by injection molding the mixed powder. Is carried out by melting and molding.

The type of bacteria expected to be a problem at a specific location of the container body 1 cannot be said to be one type. According to the inventors of the present invention, at a specific location of the container body 1, there are a plurality of types of bacteria that are expected to become a problem, and, depending on the specific location, a relatively large number of specific types of bacteria exist. Found something else.

Then, according to a plurality of types of bacteria expected to exist in a specific location, a technique ("load dispersion") of mixing and dispersing metal fine particles in the sterilization unit for effectively reducing each bacteria was considered.

In this embodiment, aerobic bacteria and anaerobic bacteria may be a problem at the positions inside the container body 1 corresponding to the fixing members 2C and 2D, but there are relatively many problems of aerobic bacteria on the upper side. In the lower part, it is expected that there will be relatively many problems of anaerobic bacteria. In addition, the fixing member 2C has a content of copper fine particles greater than that of the silver fine particles, and the fixing member 2D has a content of silver fine particles greater than that of the copper fine particles, so it is present in a specific position of the container body 1 According to a plurality of types of bacteria that are expected to be expected, each of the bacteria can be effectively reduced.

<8th embodiment>

Next, an eighth embodiment will be described with reference to FIGS. 36 to 43. Descriptions of items in common with the seventh embodiment will be omitted, and different parts will be mainly described.

As shown in Fig. 36, the non-fixing members 20C, 20D, and 20E of the eighth embodiment are formed in a cylindrical shape. The non-fixed members 20C, 20D, and 20E are sterile members. The member group is constituted by the non-fixed members 20C, 20D, and 20E. The non-fixed members 20C, 20D, and 20E are collectively referred to as "non-fixed member 20". The non-fixing member 20 is disposed in a state where it is not fixed inside the container body 1 storing the cosmetic product 200 in a liquid state. In addition, in the present specification, the term "non-fixed member" is used to mean a member that is disposed in an unfixed state.

As shown in Figs. 37 and 38, the non-fixing member 20 is composed of a wall portion 20Ha constituting the main wall of the through hole S2.

The non-fixing member 20 is constituted by dispersing a plurality of types of metals in a resin. In the non-fixing members 20C, 20D, 20E, the content of each metal fine particle is different. In addition, the specific gravity is different between the non-fixing members 20C, 20D, and 20E.

The plural kinds of metals are copper and silver in this embodiment. The non-fixing members (20C to 20E) all contain copper fine particles and silver fine particles, but the content ratio Xcu of the copper fine particles to the content of all the metal fine particles and the content ratio Xag of the silver fine particles to the content of all the metal fine particles are different.

As shown in Fig. 41, in the non-fixed member 20C, the ratio Xcu of the copper fine particles is larger than the ratio Xag of the silver fine particles. In addition, the specific gravity of the non-fixing member 20C is smaller than that of the cosmetics 200.

As shown in Fig. 42, in the non-fixed member 20D, the ratio Xcu of the copper fine particles and the ratio Xag of the silver fine particles are substantially the same. In addition, the specific gravity of the non-fixing member 20D is substantially the same as that of the cosmetics 200.

As shown in Fig. 43, in the non-fixed member 20E, the ratio Xag of the silver fine particles is larger than the ratio Xcu of the copper fine particles. In addition, the specific gravity of the non-fixing member 20E is larger than that of the cosmetic product 200.

Adjustment of specific gravity is adjusted by the kind of resin, for example. Alternatively, the specific gravity can be adjusted by dispersing metal fine particles other than copper and silver in the resin.

39 and 40, when the non-fixing members 20C to 20E are disposed in the container body 1 in which the cosmetic 200 is stored, the non-fixing member 20C is formed on the upper side of the cosmetic 200. Located in the vicinity of the surface, the non-fixing member 20D is located between the top and the bottom of the cosmetic 200, and the non-fixing member 20E is located on the bottom of the cosmetic 200.

In the vicinity of the upper surface of the cosmetic 200, mainly aerobic bacteria are a problem. In the bottom of the cosmetic 200, mainly anaerobic bacteria are a problem. Both aerobic bacteria and anaerobic bacteria are problematic in the vicinity of the surface and between the bottom of the cosmetic 200.

Since the specific gravity of the non-fixed member 20C having a large content of metal fine particles suitable for reducing aerobic bacteria is smaller than that of the cosmetic 200, it is located near the surface of the cosmetic 200 to effectively reduce aerobic bacteria. Further, since the specific gravity of the non-fixed member 20E having a large content of metal fine particles suitable for reducing anaerobic bacteria is larger than that of the cosmetic 200, it is located at the bottom of the cosmetic 200 and effectively reduces anaerobic bacteria. And, since the specific gravity of the non-fixing member 20E is substantially the same as the specific gravity of the cosmetic 200, the content of the metal fine particles suitable for reducing aerobic bacteria and the content of metal suitable for reducing anaerobic bacteria are substantially the same as the specific gravity of the cosmetic 200 200) is located in the middle of the bottom and the surface, effectively reducing aerobic and anaerobic bacteria.

<9th embodiment>

Next, a ninth embodiment will be described with reference to FIGS. 44 to 45. Descriptions of items in common with the eighth embodiment will be omitted, and different parts will be mainly described.

As shown in Fig. 44, the non-fixing member 20E of the ninth embodiment is configured in a semi-cylindrical shape. As shown in Fig. 45, the non-fixing member 20E is composed of a central portion 20Ea and outer layer portions 20Eb1 and 20Eb2. The outer layer portions 20Eb1 and 20Eb2 are constituted by a sterilization portion. That is, a part of the non-fixing member 20E is constituted by a sterilization part. The outer layer portion 20Eb1 and the outer layer portion 20Eb2 are collectively referred to as an outer layer portion 20Eb.

As in the eighth embodiment, a member group is constituted by a plurality of non-fixing members 20 0E having different specific gravity in relation to the cosmetic 200 and different content of copper fine particles and silver fine particles, A plurality of containers are arranged in the main body 1.

The non-fixing member 20E having a greater specific gravity than the cosmetic 200 is configured to be in line contact with the bottom surface of the container body 1. Thereby, metal ions are released in a larger area, and the recent can be effectively reduced.

<tenth embodiment>
