[0014] An embodiment of a cosmetic container 10 according to the present invention will be described below with reference to the drawings.

[0015] The cosmetic container 10 of this embodiment is a cosmetic container 10 that contains a cosmetic 20 and includes a holder 13 that contains an antibacterial volatile component. In the storage state, the holder 13 is arranged so as to leave a space between the holder 13 and the cosmetic 20 therein.

[0016] The cosmetic container 10 of this embodiment can exert an antibacterial effect on the cosmetic 20 contained therein. More specifically, the antibacterial volatile component exerts an antibacterial effect on the surface of the cosmetic 20 in a stored state. Therefore, it is particularly effective in the case where the cosmetic 20 comes into contact with the skin or the like and microorganisms (unwanted germs, etc.) adhere to the surface of the cosmetic 20 as a result of this contact. In particular, when the cosmetic is an oil-based preparation such as lipstick or oil-based foundation, the cosmetic does not contain enough water for microorganisms to grow, so it is difficult to be contaminated by microorganisms before use. However, after using the cosmetic, lipstick may produce an unpleasant odor, and foundation may produce mold. This is because microorganisms such as skin bacteria, moisture such as human saliva and sweat, or body surface-derived components such as peeled keratin and sebum adhere to the surface of the cosmetic during use, and the container is stored with these attached, so that microorganisms grow using the body surface-derived components as a nutrient source in the presence of the attached moisture. This causes the generation of unpleasant odors and mold. In order to prevent such a phenomenon, the preservatives contained in the cosmetic preparation, which is an oil-based preparation, need to diffuse into the adhering water and exert their preservative effect. However, because the preservatives in the oil-based preparation are hydrophobic, they cannot diffuse very much into the adhering water. In contrast, in the cosmetic container of the present embodiment, the antibacterial volatile component volatilizes and migrates to the surface of the cosmetic, thereby making it possible to inhibit the proliferation of microorganisms in the presence of moisture adhering to the cosmetic.

[0017] The cosmetic container 10 of the present embodiment is not particularly limited as long as it is a container that contains a cosmetic 20 that is applied to the skin, mucous membrane, hair, etc., or a cosmetic 20 that is diluted and then brought into contact with these for use. Specifically, the cosmetic container 10 of the present embodiment is not limited to a makeup cosmetic container or a basic cosmetic container. The cosmetic container 10 of the present embodiment also includes, for example, a toothpaste container, a hair cosmetic container, a bath additive container, etc. The subject of use may be either a human or a non-human animal. The cosmetic 20 contained in the cosmetic container 10 of the present embodiment may be classified as any of cosmetics, quasi-drugs, and medicines under the Pharmaceutical and Medical Device Act.

[0018] The cosmetic container 10 typically includes a container body 11 and a lid body (cap) 12. The cosmetic container 10 includes a holder 13 attached to, for example, the inner surface of the container body 11 or the inner surface of the lid body 12 in a storage state. The storage state refers to a state in which the cosmetic 20 is contained inside the cosmetic container 10 so as to be shielded from outside air when not in use. Usually, the storage state refers to a state in which the lid 12 (cap) is attached to the container body 11.

[0019] The container body 11 has a configuration that allows the cosmetic material 20 to be exposed to the outside air during use. On the other hand, the container body 11 has a configuration that allows a lid body 12 (cap) to be attached when not in use.

[0020] For example, the container body 11 has a configuration for storing a compressed powder foundation. Also, for example, the container body 11 has a configuration for pushing out a stick-shaped lipstick when used. Also, for example, the container body 11 has a tube shape and has a configuration for pushing out toothpaste when used by being pressed by hand.

[0021] The container body 11 may have a configuration that allows the cosmetic material 20, the amount of which has decreased due to use, to be replaced with new cosmetic material 20. In other words, the container body 11 may be so-called refillable.

[0022] The lid body 12 (cap) may be configured to be separated from the container body 11 during use. On the other hand, the lid body 12 (cap) may be configured to be connected to a part of the container body 11 without being separated from the container body 11 during use.

[0023] The lid body 12 (cap) is preferably configured so as not to come into contact with at least a portion of the surface of the cosmetic material 20 when attached to the container body 11. In other words, the lid body 12 (cap) is preferably configured so as to be separated from at least a portion of the surface of the cosmetic material 20 when attached to the container body 11. The holder 13 may be attached to a portion of the lid body 12 separated from the surface of the cosmetic material 20.

[0024] The support 13 has a substrate that supports the antibacterial volatile component or the essential oil containing the component. The material of the substrate is not particularly limited, but examples thereof include polymer compounds such as polysaccharides and synthetic resins. Examples of the substrate include a resin sheet or a nonwoven fabric. Examples of the nonwoven fabric include paper made of cellulose fibers and a fiber sheet made of synthetic fibers.

[0025] The support 13 has a structure that gradually releases the antibacterial volatile component or the essential oil containing the component. In other words, the support 13 is a sustained release material for the antibacterial volatile component or the component. More specifically, the base material of the support 13 includes a synthetic resin and capsule particles dispersed in the synthetic resin. The capsule particles have a hollow portion that contains an antibacterial volatile component and an outer membrane portion that surrounds the hollow portion.

[0026] The hollow portion of the capsule particle contains an antibacterial volatile component. An essential oil (described in detail below) containing the antibacterial volatile component may be present in the hollow portion. The hollow portion may contain an oil and an antibacterial volatile component dissolved in the oil. The oil may be edible oil or fat. The edible oil or fat contains an ester of glycerin and a fatty acid (triglyceride).

[0027] The outer membrane of the capsule particle is hygroscopic and contains at least one selected from the group consisting of gum arabic, gelatin, hemicellulose, microbial polysaccharides, and modified starch. Specifically, the outer membrane is composed of a membrane containing at least one selected from the group consisting of gum arabic, gelatin, hemicellulose, microbial polysaccharides, and modified starch. With such an outer membrane, the antibacterial volatile component in the hollow portion is not released to the outside of the outer membrane in a relatively low humidity environment. On the other hand, the antibacterial volatile component is easily released to the outside of the outer membrane in a relatively high humidity environment where microorganisms can grow actively. As a result, the antibacterial volatile component in the hollow portion is released in a relatively large amount in a high humidity environment where microorganisms can grow easily, and the antibacterial volatile component in the hollow portion is not released to the outside of the outer membrane in a low humidity environment where microorganisms do not grow much. In other words, the capsule particles can have humidity responsiveness. The outer membrane preferably contains at least one of gum arabic and modified starch.

[0028] The synthetic resin contained in the base material is not particularly limited, but examples thereof include acrylic resin, olefin resin such as polyethylene and polypropylene, and polyester resin such as polyethylene terephthalate.

[0029] The capsule particles may have an average particle size of 2 μm or more and 150 μm or less.

[0030] The capsule particles contained in the support 13 can be produced, for example, as follows. In the preparation of capsule particles, a mixed liquid containing at least the antibacterial volatile component, water, and gum arabic or the like that constitutes the outer membrane is prepared. If necessary, an oil or excipient that dissolves the antibacterial volatile component is also added to prepare the mixed liquid. In this mixed liquid, gum arabic or the like functions as an emulsifier, and the antibacterial volatile component or the like is dispersed in water in an emulsified state. The emulsified mixed liquid is spray-dried to prepare capsule particles in which the antibacterial volatile component is disposed inside the outer membrane. Specific examples of excipients include starch, starch hydrolysates, dextrin, monosaccharides such as glucose, and disaccharides such as lactose.

[0031] The capsule particles prepared as described above are humidity responsive to the release of antimicrobial volatiles. For example, the capsule particles do not release antibacterial volatile components (below the detection limit) at a humidity of 50% at a given temperature, but release antibacterial volatile components at a humidity of 70%. An environment with a humidity of 70% is an environment in which fungi (mold, yeast) are likely to grow. The above capsule particles release antibacterial volatile components in a humid environment where fungi are likely to grow, but release little of the antibacterial volatile components in an environment where fungi do not necessarily grow actively, so the support 13 containing the above capsule particles has better sustained release properties of the antibacterial volatile components. Although the temperature at which fungi (mold, yeast) tend to grow is around room temperature (for example, about 25°C), fungi (mold, yeast) can grow at higher temperatures. The support 13 containing the above-mentioned capsule particles and the antibacterial volatile components within the particles has the above-mentioned sustained release properties at around room temperature, and the capsule particles are less likely to disintegrate even at higher temperatures, so the sustained release properties are also maintained. Therefore, whether at around room temperature or at higher temperatures, the antibacterial volatile components are released from the capsule particles, and the antibacterial effect is exerted.

[0032] The base material of the holder 13 is prepared, for example, by forming the synthetic resin containing the capsule particles into a sheet shape.

[0033] The support 13 contains an antibacterial volatile component in addition to the base material. The support 13 may contain an essential oil containing the antibacterial volatile component.

[0034] The retaining body 13 is disposed so as to leave a space between the cosmetic material 20 and the retaining body 13 when the cosmetic material 20 is not in use and is stored inside the cosmetic container 10. In other words, the retaining body 13 is disposed so as not to come into contact with the cosmetic material 20 and to provide air between the retaining body 13 and the cosmetic material 20 when the cosmetic material 20 is stored.

[0035] The cosmetic container 10 shown in FIG. 1 has a lid body 12 consisting of an inner lid 12a and an outer lid 12b. As shown in FIG. 1, for example, the holder 13 may be attached to the inner surface of the inner lid 12a of the foundation container. 1 is configured to contain a foundation and a sponge S (puff) for applying the foundation to the skin. Such a container includes an inner lid 12a for covering the surface of the foundation, and an outer lid 12b for covering the inner lid 12a covering the foundation and the sponge S (puff). A mirror is attached to the inner surface of the outer lid 12b. In the storage state where the inner lid 12a and the outer lid 12b of the container are closed, the holder 13 attached to the inner surface of the inner lid 12a is slightly spaced from the surface of the foundation. In this storage state, the antibacterial volatile components or essential oils gradually released from the holder 13 can exert an antibacterial effect on the foundation (cosmetic material 20). Such a container has a packing P in the portion that contains the foundation, and is configured so that the space in contact with the surface of the foundation can be sealed by closing the inner lid 12a.

[0036] As shown in FIG. 2, for example, the holder 13 may be disposed on a part of the periphery of a recess that accommodates the sponge S in a foundation container. 2 is configured to accommodate a foundation and a sponge S (puff) for applying the foundation to the skin. The container is formed with a recess for accommodating the foundation and a recess for accommodating the sponge S. The container is also provided with a lid 12 for covering the foundation and the sponge S. A mirror is attached to the inner surface of the lid 12. In a storage state with the lid 12 of the container closed, the holder 13 arranged on a part of the periphery of the recess that contains the sponge S is spaced apart from the surface of the foundation. In this storage state, the antibacterial volatile components or essential oils gradually released from the holder 13 can exert an antibacterial effect on the foundation (cosmetic material 20). In addition, such a container does not seal the internal space (space in contact with the surface of the foundation) even when the lid 12 is closed, that is, it is a non-sealed container.

[0037] As shown in FIG. 3, for example, the holder 13 may be attached to the inner surface of the lid 12. The container shown in Fig. 3 is configured to store a foundation. The container has a recess for storing the foundation. The container also includes a lid 12 for covering the foundation. A holder 13 is attached to the inner surface of the lid 12. In the storage state where the lid 12 of such a container is closed, the holder 13 attached to the inner surface of the lid 12 is slightly spaced from the surface of the foundation. In this storage state, the antibacterial volatile components or essential oils gradually released from the holder 13 can exert an antibacterial effect on the foundation (cosmetic material 20). The cosmetic container 10 shown in Fig. 3 is configured so that the stored foundation can be replaced with a new foundation. In other words, the cosmetic container 10 shown in Fig. 3 is configured so that the foundation can be refilled. Moreover, this container has a ring-shaped packing P attached to the inner surface of the lid 12, and is configured such that by closing the lid 12, the space in contact with the surface of the foundation can be sealed.

[0038] The cosmetic container 10 shown in FIG. 4 has a similar configuration to the cosmetic container 10 shown in FIG. 3, but is not refillable. Such a container has a packing P attached to the inner surface of the lid 12, and is configured such that by closing the lid 12, the space in contact with the surface of the foundation can be sealed.

[0039] As shown in FIG. 5, for example, the holder 13 may be attached to the inner surface of the lid 12. The container shown in Fig. 5 is configured to store foundation. Such a container stores foundation inside a container body 11. The container is configured to push out a small amount of foundation by pressing the container body 11 from the outside. Also, the container is provided with a lid 12 for covering a portion of the foundation that is exposed to the outside air. A holder 13 is attached to the inner surface of the lid 12. In the storage state where the lid 12 of such a container is closed, the holder 13 attached to the inner surface of the lid 12 is slightly spaced from the surface of the foundation. In this storage state, the antibacterial volatile components or essential oils gradually released from the holder 13 can exert an antibacterial effect on the foundation (cosmetic material 20).

[0040] As shown in FIG. 6, for example, the holder 13 may be attached to the inner surface of the lid 12. The container shown in Fig. 6 is configured to store emulsion (milky cosmetic). Such a container stores emulsion inside container body 11. It is configured to dispense a small amount of emulsion by inverting container body 11 upside down. It also includes a lid 12 for attachment to container body 11. A holder 13 is attached to the inner surface of lid 12. In a storage state where the lid 12 of such a container is closed, the support 13 attached to the inner surface of the lid 12 is slightly spaced from the surface of the lotion. In this storage state, the antibacterial volatile components or essential oils gradually released from the support 13 can exert an antibacterial effect on the lotion (cosmetic).

[0041] As shown in Fig. 7, for example, the holder 13 may be attached to the inner surface of the lid 12 of a tube container that contains paste. The paste may be toothpaste. The container shown in the cross-sectional view of Fig. 7 has a configuration for storing paste. The paste is stored inside the container body 11. The container body 11 is configured to push out a small amount of paste by pressing the container body 11 from the outside. The container also has a lid 12 for covering a portion of the paste that is exposed to the outside air. A holder 13 is attached to the inner surface of the lid 12. In the storage state with the lid 12 of such a container closed, the holder 13 attached to the inner surface of the lid 12 is slightly spaced from the surface of the paste. In this storage state, the antibacterial volatile components or essential oils gradually released from the holder 13 can exert an antibacterial effect on the paste (cosmetic material 20).

[0042] As shown in FIG. 8, for example, the holder 13 may be attached to the inner surface of a lid 12 in a container that contains a stick-shaped solid product such as lipstick. The container shown in the cross-sectional view of Fig. 8 is configured to store lipstick. Such a container stores lipstick inside container body 11. The container is configured so that the lipstick can be advanced outward in one direction by rotating a portion of container body 11. The container also includes a lid 12 for covering the portion of the lipstick that is exposed to the outside air. A holder 13 is attached to the inner surface of lid 12. In the storage state with the lid 12 of such a container closed, the holder 13 attached to the inner surface of the lid 12 is spaced apart from the surface of the lipstick. In this storage state, the antibacterial volatile components or essential oils gradually released from the holder 13 can exert an antibacterial effect on the lipstick (cosmetic material 20). The cosmetic 20 contained in the cosmetic container 10 shown in Figures 3 to 8 may be a concealer, a beauty essence, a cream, a cleansing agent, a facial cleanser, an eye shadow, a blush, a lip cream, a gel, a lotion, a sunscreen, a makeup base, a hand cream, a body cream, a highlighter, or the like.

[0043] As described above, it is preferable that the holder 13 is disposed so as not to be noticeable in appearance when the lid 12 is not attached to the container body 11.

[0044] The support 13 preferably contains, as an antibacterial volatile component, at least one selected from the group consisting of allyl isothiocyanate, terpinene (particularly α-terpinene and γ-terpinene), geraniol, citronellol (particularly β-citronellol), terpinen-4-ol (d- and l-forms), menthol (particularly l-menthol), linalool, citral (geranial and neral), terpineol (particularly α-terpineol), citronellal (d- and l-forms), and 1,8-cineole. As these antibacterial volatile components, commercially available products can be used.

[0045] The support 13 may contain at least one essential oil containing an antibacterial volatile component selected from the group consisting of wasabi essential oil, coriander essential oil, sweet marjoram essential oil, geranium essential oil, neroli essential oil, basil essential oil, peppermint essential oil, melissa essential oil, eucalyptus essential oil, lavender essential oil, rosewood essential oil, rose otto essential oil, rosemary essential oil, lemongrass essential oil, tea tree essential oil, lemon essential oil, ylang-ylang essential oil, clary sage essential oil, petitgrain essential oil, bergamot essential oil, spearmint essential oil, and pimento essential oil. These essential oils can be commercially available products. These essential oils are usually obtained by steam distillation, compression, or the like.

[0046] By containing the essential oil components in the retaining body 13, the antibacterial volatile components can exert an antibacterial effect on the cosmetic 20, and since the antibacterial volatile components do not have an unpleasant odor, the commercial value of the cosmetic 20 can be prevented from being reduced. In particular, when the cosmetic 20 is an oil-based preparation such as lipstick or foundation, the problematic microorganisms that may grow on the surface of the cosmetic 20 are fungi (yeast, mold). The cell structure of fungi is more evolved than that of bacteria and is closer to that of higher organisms. Therefore, even if a bactericide has a sufficient antibacterial effect on bacteria with a simple cell structure, it often does not have a sufficient bactericidal effect on fungi with a complex and evolved cell structure. In other words, there are few bactericides that have a bactericidal effect on fungi. For example, the vapor of a common preservative ingredient for cosmetics, such as ethanol or phenoxyethanol, does not have a good antibacterial effect on fungi. On the other hand, bactericides that have a bactericidal effect on fungi may be toxic to humans, so there are not many antifungal agents (medicines) that are safe. In contrast, the essential oils and the antibacterial volatile components contained therein exhibit antibacterial effects specifically against Bacillus subtilis and fungi. As will be understood from the examples below, the vapor of the antibacterial volatile components and the vapor of the essential oils containing the antibacterial volatile components exhibit antibacterial effects against fungi. Examples of microorganisms that may grow on the surface of the cosmetic 20 include bacteria of the genus Staphylococcus, bacteria of the genus Kocuria, bacteria of the genus Micrococcus, bacteria of the genus Bacillus, fungi of the genus Candida, fungi of the genus Cryptococcus, and fungi of the genus Rhodotorula. Specifically, Staphylococcus aureus, Staphylococcus hominis, Staphylococcus capitis, Staphylococcus lentus, Kocuria varians, Micrococcus spp., Bacillus subtilis, Bacillus licheniformis, Candida boidinll, Candida parapsilosis, Candida guilliermondii, Candida zeylanoides, Candida guilliermondii, Candida albicans, Candida tropicalis, Candida dubliniensis, Candida guilliermondii, Candida tropicalis, Candida parapsilosis, Cryptococcus albidus, Cryptococcus humicola, Rhodotorula glutinis, etc.

[0047] Allyl isothiocyanate is contained in wasabi essential oil. Terpinene is contained in coriander, sweet marjoram, neroli, lemon, and tea tree essential oils. Geraniol is contained in ylang-ylang, coriander, geranium, neroli, eucalyptus, rosewood, rose otto, tea tree, and lemongrass essential oils. Citronellol is contained in geranium, melissa, rose otto, tea tree, and lemongrass essential oils. Terpinen-4-ol is contained in sweet marjoram, basil, lavender, and tea tree essential oils. Menthol is contained in peppermint essential oil. Linalool is contained in ylang-ylang, clary sage, coriander, geranium, neroli, basil, petitgrain, bergamot, eucalyptus, lavender, rosewood, and rose otto essential oils. Terpineol is contained in eucalyptus and rosewood essential oils. Citronellal is found in geranium, melissa, and rose otto essential oils. Citrals such as neral and geranial are found in melissa, lemon, and lemongrass essential oils. 1,8-cineole is found in basil, peppermint, eucalyptus, lavender, rosemary, tea tree, spearmint, and pimento essential oils.

[0048] The antibacterial volatile component is preferably at least one selected from the group consisting of terpinene, terpinen-4-ol, citronellal, 1,8-cineole, allyl isothiocyanate, geraniol, citronellol, linalool, citral, and terpineol, and more preferably at least two selected from the group consisting of terpinene, terpinen-4-ol, citronellal, 1,8-cineole, allyl isothiocyanate, geraniol, citronellol, linalool, citral, and terpineol. The antibacterial volatile component is more preferably at least one selected from the group consisting of allyl isothiocyanate, geraniol, citronellol, linalool, citral, and terpineol, and even more preferably at least two selected from the group consisting of allyl isothiocyanate, geraniol, citronellol, linalool, citral, and terpineol. As the antibacterial volatile component, at least one selected from the group consisting of allyl isothiocyanate, linalool, and citral is particularly preferred, and allyl isothiocyanate is most preferred.

[0049] Examples of antibacterial volatile components include alcohol-based antibacterial volatile components (including phenol-based antibacterial volatile components) and aldehyde-based antibacterial volatile components. Examples of alcohol-based antibacterial volatile components include geraniol, citronellol, terpinen-4-ol, menthol, linalool, and terpineol. Examples of aldehyde-based antibacterial volatile components include citral such as neral (cis-form) and geranial (trans-form), and citronellal. The alcohol-based antibacterial volatile component and the essential oil containing these components have a cell membrane disrupting effect. In addition, the aldehyde-based antibacterial volatile component and the essential oil containing the component have an effect of reacting with nucleophilic functional groups in cells. Therefore, by combining the alcohol-based antibacterial volatile component and the aldehyde-based antibacterial volatile component and containing them in the support 13, it is possible to exert an antibacterial effect against microorganisms through different action mechanisms. In detail, by disrupting the cell membrane with the alcohol-based antibacterial volatile component, the aldehyde-based antibacterial volatile component is more likely to enter the cell. This makes it easier for the aldehyde-based antibacterial volatile component to react with nucleophilic functional groups in cells. Therefore, by combining the alcohol-based antibacterial volatile component and the aldehyde-based antibacterial volatile component, it is possible to exert a synergistic antibacterial effect.

[0050] In terms of combining an alcohol-based antibacterial volatile component with an aldehyde-based antibacterial volatile component to exert a synergistic antibacterial effect, the antibacterial volatile component preferably contains at least one selected from the group consisting of geraniol, citronellol, terpinen-4-ol, menthol, linalool, and terpineol, and at least one of citral and citronellal, and more preferably contains allyl isothiocyanate. More preferably, the antibacterial volatile component contains linalool as an alcohol-based antibacterial volatile component and citral as an aldehyde-based antibacterial volatile component, and particularly preferably further contains allyl isothiocyanate. This allows the antibacterial effect to be exerted more synergistically.

[0051] In the antibacterial volatile component, the capacity ratio (volume ratio) of the alcohol-based antibacterial volatile component to the aldehyde-based antibacterial volatile component is preferably 5 times or more and 10 times or less, more preferably 6 times or more and 8 times or less. In particular, the capacity ratio (volume ratio) of linalool to citral is preferably within the above-mentioned numerical range.

[0052] The essential oil is preferably at least one selected from the group consisting of wasabi essential oil, coriander essential oil, sweet marjoram essential oil, geranium essential oil, neroli essential oil, basil essential oil, peppermint essential oil, melissa essential oil, eucalyptus essential oil, lavender essential oil, rosewood essential oil, rose otto essential oil, rosemary essential oil, lemongrass essential oil, tea tree essential oil, lemon essential oil, ylang-ylang essential oil, clary sage essential oil, petitgrain essential oil, and bergamot essential oil, and more preferably at least two selected from the group consisting of wasabi essential oil, coriander essential oil, sweet marjoram essential oil, geranium essential oil, neroli essential oil, basil essential oil, peppermint essential oil, melissa essential oil, eucalyptus essential oil, lavender essential oil, rosewood essential oil, rose otto essential oil, rosemary essential oil, lemongrass essential oil, tea tree essential oil, lemon essential oil, ylang-ylang essential oil, clary sage essential oil, petitgrain essential oil, and bergamot essential oil. Furthermore, the essential oil is more preferably at least one selected from the group consisting of wasabi essential oil, coriander essential oil, sweet marjoram essential oil, geranium essential oil, neroli essential oil, basil essential oil, peppermint essential oil, melissa essential oil, eucalyptus essential oil, lavender essential oil, rosewood essential oil, rose otto essential oil, rosemary essential oil, lemongrass essential oil, and tea tree essential oil, and particularly preferably at least one selected from the group consisting of wasabi essential oil, geranium essential oil, and lavender essential oil.

[0053] As the essential oil, wasabi essential oil containing allyl isothiocyanate, which is obtained from the edible plant wasabi, is particularly preferred. By using allyl isothiocyanate as the antibacterial volatile component or wasabi essential oil as the essential oil, it can be said that the cosmetic container 10 has better safety for the human body.

[0054] Furthermore, as described above, since an antibacterial volatile component that is a combination of linalool and citral is preferred, it is preferable to combine an essential oil containing linalool with an essential oil containing citral. For example, holder 13 may contain at least one essential oil (containing linalool) selected from the group consisting of ylang-ylang essential oil, clary sage essential oil, coriander essential oil, geranium essential oil, neroli essential oil, basil essential oil, petitgrain essential oil, bergamot essential oil, eucalyptus essential oil, lavender essential oil, rosewood essential oil, and rose otto essential oil, and at least one essential oil (containing citral) selected from the group consisting of lemongrass essential oil, lemon essential oil, and melissa essential oil, and in addition to these essential oils, holder 13 may further contain wasabi essential oil. More preferably, the support 13 contains at least one of geranium essential oil and lavender essential oil, and at least one essential oil selected from the group consisting of lemongrass essential oil, lemon essential oil, and melissa essential oil, and particularly preferably, the support 13 contains wasabi essential oil in addition to these essential oils.

[0055] In the cosmetic container 10 of this embodiment, the holder 13 is attached to the inner surface of the lid 12 and preferably contains wasabi essential oil. This allows the holder 13 to exert a sufficient antibacterial effect on the cosmetic 20 while being less noticeable.

[0056] When the cosmetic container 10 of this embodiment contains and stores the cosmetic 20, the ratio (L / V) of the volume (L) of the essential oil in the holder 13 to the volume (V) of the space separating the holder 13 and the cosmetic 20 is 0.5 [μL / cm 3 ] or more than 1.5[μL / cm 3 The above-mentioned internal space volume is the volume of the space that can be filled with the antibacterial volatile components volatilized from the holder 13. This allows the antibacterial effect to be sufficiently exerted with a relatively small amount of essential oil. When using basil essential oil, coriander essential oil, peppermint essential oil, melissa essential oil, neroli essential oil, eucalyptus essential oil, rose otto essential oil, sweet marjoram essential oil, rosewood essential oil, or geranium essential oil, the antibacterial effect is exerted even with a smaller amount of essential oil, and the above-mentioned ratio (L / V) is preferably 0.05 [μL / cm 3 ] or higher, sufficient antibacterial properties are exhibited. Similarly, the ratio (L / V) of the volume (L) of the antibacterial volatile component in the support 13 to the volume (V) of the space separating the support 13 and the cosmetic 20 is 0.1 [μL / cm 3 ] or more 0.3[μL / cm 3 ] or less. This allows the antibacterial action to be fully exerted with a relatively small amount of antibacterial volatile component. When citronellol (particularly β-citronellol), citral, or geraniol is used, the antibacterial action is exerted even with a smaller amount of antibacterial volatile component, and the above ratio (L / V) is preferably 0.05 [μL / cm 3 ] or higher, sufficient antibacterial properties are exhibited.

[0057] The cosmetic container 10 of the present embodiment may include a plurality of retaining bodies 13, and the plurality of retaining bodies 13 may be spaced apart from one another. The plurality of retaining bodies 13 may all contain the same antibacterial volatile component or the same essential oil, or the plurality of retaining bodies 13 may each contain a different antibacterial volatile component or essential oil.

[0058] Next, one embodiment of the cosmetic product according to the present invention will be described.

[0059] The cosmetic product 1 of the present embodiment includes the above-mentioned cosmetic container 10 and a cosmetic 20 contained in the cosmetic container 10.

[0060] The cosmetic 20 is not particularly limited, and examples thereof include lipstick, external skin cosmetics (cosmetics for facial skin around the eyes, etc.), hair cosmetics, and oral cosmetics (toothpaste, etc.).

[0061] The cosmetic material 20 is composed of a cosmetic composition. The cosmetic composition contains water, oil, and the like. In addition to the above, the cosmetic composition may contain components that are generally incorporated into cosmetics and topical skin preparations. Examples of components that the composition of the present embodiment may contain include polyhydric alcohols such as dipropylene glycol, glycerin, pentylene glycol, propylene glycol, 1,3-butylene glycol, and diglycerin. Other examples of components that may be included include surfactants, preservatives, antioxidants, anti-inflammatory agents, ultraviolet absorbing agents, ultraviolet scattering agents, vitamins, and enzymes. The cosmetic composition is composed of ingredients specified in the Quasi-drug Raw Materials Standards, Cosmetic Type Ingredient Standards, Cosmetic Raw Materials Standards, Japanese Pharmacopoeia, Food Additives Official Standards, etc.

[0062] The form of the cosmetic material is not particularly limited, and may be, for example, a solid (such as compressed solid powder or wax), liquid, powder, or paste.

[0063] Next, a method for producing the cosmetic container 10 and the cosmetic product 1 according to the present invention will be described.

[0064] The cosmetic container 10 of this embodiment can be manufactured, for example, by attaching the holder 13 to a specific portion of a commercially available container supplied by a container manufacturer. The cosmetic product 1 of this embodiment can be produced, for example, by placing the above-mentioned cosmetic product 20 in the cosmetic product container 10 produced as described above in a general manner.

[0065] The cosmetic 20 is an external preparation for the human body that can be applied to, for example, the skin of the face, the skin of the neck, the skin of the limbs, the scalp, the hair, and mucous membranes (mucous membranes of the nostrils, lips, ears, genitals, anus, etc.). The composition is not particularly restricted by classifications such as cosmetics, quasi-drugs, and pharmaceuticals under the Pharmaceutical and Medical Device Act, and is applicable to several fields.

[0066] The cosmetic container and the cosmetic of the present invention are as exemplified above, but the present invention is not limited to the above-exemplified embodiments. In addition, in the present invention, various forms adopted in general cosmetics and the like can be adopted within a range that does not impair the effects of the present invention.

[0067] Although the cosmetic container in the above embodiment is provided with a holder containing an antibacterial volatile component, the cosmetic container of the present invention is not limited to this. For example, in the cosmetic container of the present invention, the container body or the lid may be made of a material containing an antibacterial volatile component. Specifically, the cosmetic container of the present invention may include a container body or a lid containing the above-mentioned capsule particles. EXAMPLES

[0068] The present invention will now be described in more detail with reference to examples, but the present invention is not limited to these.

[0069] <Antibacterial activity evaluation test against fungi (yeast) using supports containing essential oils, simple alcohols, etc.> The test method is as follows. The internal volume is approximately 73 cm 3 A petri dish was prepared. Various essential oils and antibacterial volatile components were impregnated into the base material (filter paper). A support was attached to the inner surface of the petri dish lid. In each test, the amount of essential oil impregnated was 50 μL, and the amount of antibacterial volatile components, etc. impregnated was 10 μL. In addition, a petri dish (blank sample) was also prepared, in which a base material (filter paper) that had not been impregnated with anything was attached to the inner surface of the lid. The fungi used in the test were as follows (a mixture of Candida fungi (yeasts)). Candida albicans Candida parapsilosis Candida tropicalis Candida zeylanoides Candida guilliermondii Candida dubliniensis Candida zeylanoides The outline of the test method is shown in Figure 9. A yeast liquid was smeared on a fungal medium (c-GPLP) (Figure 9 (a)). The petri dish was covered with a lid to which a support (filter paper) containing each of the essential oils and substances listed below was attached, and the dish was cultured in an inverted state at 25°C for 5 days (Figure 9 (b) and (c)). The results are shown in Figures 10 to 15. The fewer the colony counts, the stronger the antibacterial effect. By providing a support containing the specific essential oil or antibacterial volatile component corresponding to the examples, the antibacterial effect was sufficiently exerted. In addition, when basil essential oil, coriander essential oil, peppermint essential oil, melissa essential oil, neroli essential oil, eucalyptus essential oil, rose otto essential oil, sweet marjoram essential oil, rosewood essential oil, and geranium essential oil were used, sufficient antibacterial properties were exhibited even with an impregnation amount as small as 5 μL.In addition, when citronellol, citral, and geraniol were used, sufficient antibacterial properties were exhibited even with an impregnation amount as small as 5 μL.

[0070] The antibacterial activity evaluation test was carried out in the same manner as above. The essential oils and simple alcohols contained in each support are as follows. Wasabi essential oil (contains allyl isothiocyanate) Geranium essential oil (Contains geraniol, citronellol, citronellal, linalool, etc.) Lavender essential oil (Contains linalool, terpinen-4-ol, 1,8-cineole, etc.) Phenoxyethanol ·ethanol Photographs showing the appearance of each petri dish after the bacteria test are shown in Figure 16. Many microorganisms (yeast) survived in the petri dishes using supports containing phenoxyethanol or ethanol, as well as in the blank sample. On the other hand, few microorganisms (yeast) survived in the petri dishes using supports containing wasabi essential oil, geranium essential oil, and lavender essential oil, each of which contains allyl isothiocyanate, demonstrating the antibacterial effect against yeast. It can be said that the antibacterial action is exerted by the antibacterial volatile components contained in each essential oil.

[0071] <Antibacterial effect of wasabi essential oil (containing allyl isothiocyanate) against fungi (yeast)> The presence or absence of antibacterial action against fungi (yeast) was confirmed for the cosmetic container shown in FIG. 8 when it had and did not have a support (a sheet containing wasabi essential oil). The details of the test method are as follows: Lipstick (commercially available) contaminated with microorganisms (a mixture of the above-mentioned fungi (yeasts)) was cultured for three weeks at 25°C and 80% humidity, after which the surface was wiped with a sterile cotton swab and smeared on a fungal medium (c-GPLP). It was then cultured for five days at 25°C, and the medium after the culture process was observed (bacteria test results). Lipstick contaminated with microorganisms (same as above) was cultured for 3 weeks at 25°C and 80% humidity, after which the cultured bacteria were collected in phosphate buffer. The collected bacterial solution was used for a culture treatment at 25°C for 5 days, and the number of live bacteria was calculated by colony count (viable bacteria test results). The results are shown in Figure 17. In the container without a support, many fungi (yeasts) survived, even though the lipstick contained a preservative. On the other hand, in the container with a support containing wasabi essential oil, almost no fungi (yeasts) were found to survive on the surface of the lipstick, demonstrating an antibacterial effect against fungi.

[0072] <Off-flavor test using wasabi essential oil> A support containing wasabi essential oil (a film-like sheet containing capsule particles containing wasabi essential oil and synthetic resin) was attached to the underside of the top surface of the lid of a lipstick container, and the lipstick with a surface contaminated with fungus (yeast) was then cultured for three weeks at 25°C and 80% humidity. The presence or absence of an unpleasant odor was determined by sensory evaluation. As a result, no off-odor was generated in the lipstick container equipped with a support containing wasabi essential oil. Considering the results of the above bacteria test, it is thought that an off-odor test would be generated if a lipstick container equipped with a support containing phenoxyethanol or ethanol were similarly performed.

[0073] The above test results show that by attaching a sheet (support) containing wasabi essential oil to the inside of a container, it is possible to inhibit the growth of bacteria that can cause unpleasant odors, and also to suppress the generation of unpleasant odors.

[0074] <Antibacterial activity evaluation test against fungi (yeast) using a support containing antibacterial volatile components> The fungi used in the test were a mixture of fungi (yeasts) as described above. (1) 2.0×10 5 A test bacterial solution was prepared in phosphate buffered saline (PBS) to a concentration of cfu / mL. (2) 0.45 mL of fungal medium (c-PDB medium) and 0.05 mL of test bacteria solution (10 4 cfu) and phosphate buffer (1.5 mL of PBS) were directly added and mixed inside. (3) A support made of 25 mm x 25 mm filter paper (substrate) impregnated with each sample (at least one of citral or linalool) was suspended by a string and placed in the internal space of the above-mentioned glass vial (see Figure 18). (4) The glass vial was placed in a desiccator with a humidity of 80%. (5) After 2 hours, a sample was taken, diluted with Letheen, and mixed with a fungal medium (c-GPLP agar medium) to confirm the number of remaining bacteria. The results are shown in Table 1 and FIG.

[0075] [Table 1]

[0076] As can be seen from the above results, it was confirmed that citral (containing neral and geranial) and linalool each have antibacterial activity against fungi. In particular, it was confirmed that a synergistic antibacterial effect was exhibited by using citral and linalool in combination.

[0077] Furthermore, it can be reasonably assumed that if the above antibacterial activity evaluation test is carried out using essential oils containing citral or essential oils containing linalool, results similar to those described above will be obtained. It can be reasonably assumed that similar results to those described above will be obtained when a support containing the above-mentioned capsule particles (containing antibacterial volatile components) is used as the support. For reference, a lipstick composition was placed at the bottom of a glass vial as shown in FIG. 18 and an evaluation test of the antibacterial activity was carried out in the same manner as above, and the same results as those described above were obtained. [Industrial Applicability]

[0078] The cosmetic container and the cosmetic of the present invention are used, for example, for applying the cosmetic contained in the container to the skin, mucous membrane, etc. Specifically, the cosmetic container and the cosmetic of the present invention are suitably used, for example, for applying lipstick or foundation to the face.
