  Embodiments of the present invention are described below with reference to the accompanying drawings.

  In the first embodiment, it is assumed that the upper and lower portions (indicated by reference numerals U and D) of the coating container are along the top and bottom of the sheet of FIG. The coating container in FIG. 1, the coating portion in FIG. 2, the main body and the front shaft in FIG. 3, and the comb body in FIG. 4 are also rotationally symmetrical with respect to the central axis C, and each central axis C is indicated by a chain line. ing.

  As shown in FIG. 1, the application container includes an application unit 10, a main body 12, and a tip shaft 14.

  The application section 10 includes an application body 16 that can impregnate the application liquid, and a comb body 18 having an outer periphery of the application body 16 surrounded by a series of comb teeth 18d.

  The main body 12 is a tank that stores the coating liquid in an internal space whose upper end is closed by the front shaft 14. In the embodiment, the coating liquid is a hair dye. Details of the hair dye will be described later.

  The leading shaft 14 is formed with a liquid supply hole 20 for supplying the application liquid in the main body 12 to the application body 16, and has a configuration in which the application unit 10 is detachable.

  In the application container, the application body 16 faces the liquid supply hole 20 when the application unit 10 is mounted on the tip shaft 14.

  When using the application container, first, the user puts the application unit 10 on the front shaft 14 (closes). When the user shakes the coating container up and down (U direction and D direction) or reverses the coating container, the coating liquid is supplied to the coating body 16 through the liquid supply hole 20 and is impregnated. Thereafter, the user applies the comb body 18 and the application body 16 to the hair, and applies the hair to the hair via the application body 16 while combing with the comb body 18.

The specific configuration of each part will be described below.
[Coating section 10]
In the application section 10, as shown in FIGS. 1 and 2, the comb body 18 is fitted inside a cup-shaped cap 22 having one end closed and the other end opened. A front shaft 14 is fitted to the front end side of the main body 12. The application unit 10 has a structure that is detachably attached to the tip shaft 14.

[Cap 22]
The cap 22 has a bowl-shaped outer peripheral wall main body, and a double cylindrical wall (an outer wall 22a and an inner wall 22b) is formed inside a body in which the bowl is turned down. A space 22c is formed between the inner surface of the main body of the cap 22 and the outer surface of the outer wall 22a. When the cap 22 is mounted on the front shaft 14, the end of the tube 14a inside the front shaft 14 is fitted and fixed in the space 22c to secure airtightness.

  A rib 22d is formed on a portion of the inner wall of the main body of the cap 22 that faces the space 22c in a ridge shape along the vertical direction. The rib 22d contacts the outer surface of the cylinder 14a inserted into the space 22c. The rib 22d presses the inner surface of the cylinder 14a so as to fit and closely contact the outer surface of the outer wall 22a. This pressing causes close contact and airtightness is ensured. This hermetic portion may be kept airtight by screw connection instead of fitting.

  The inner wall 22b has a cylindrical shape. The upper side (U side in FIG. 1) of the tube 18a inside the comb body 18 is fitted into the wall 22b. An uneven portion 22b1 is formed annularly on the inner peripheral surface of the wall 22b. An uneven portion 18a1 is formed on the outer peripheral surface of the inner cylinder 18a. When the inner tube 18a is fitted into the wall 22b, the uneven portion 18a1 goes over the uneven portion 22b1, and the inner tube 18a is tightly locked to the wall 22b.

[Comb 18]
The comb body 18 is provided with a table 18b on which the application body 16 is mounted downward, below the inner cylinder 18a (D side in FIG. 1).

  As shown in detail in FIG. 4, the base 18b of the comb body 18 is shaped like a circular dish, and a shaft 18c for attaching the application body 16 is formed at the center of the base 18b so as to protrude downward.

  A plurality of comb teeth 18d to be combs are formed around the base 18b so as to extend below the position of the base 18b. An area surrounded by the downward portion of the base 18b and the comb teeth 18d is a portion where the application body 16 is mounted. An outer cylinder 18e extends upward from the periphery of the table 18b. The outer peripheral surface of the outer cylinder 18e is a part facing the inner peripheral surface of the cylinder 14a of the front shaft 14.

  The axis 18c is along the central axis C in FIG. The application body 16 is attached to the comb body 18 by tightly inserting or pressing the shaft 18c into the central hole 16a of the application body 16.

  As shown in FIG. 2, the application unit 10 has a structure in which the comb teeth 18d surround the application body 16 in a state where the application body 16 is attached to the base 18b. Therefore, the application section 10 has a structure in which the comb body 18 having the plurality of comb teeth 18 d is attached to the cap 22 together with the application body 16. In FIG. 4, an uneven portion 18a1 for fitting to the outer peripheral surface of the inner cylinder 18a is formed on the peripheral surface.

[Point 14, liquid supply hole 20]
As shown in FIG. 3, the front shaft 14 has a substantially wall-shaped bottom 14b having irregularities and holes (liquid supply holes 20) at the lower part of the cylinder 14a. The front shaft 14 has a substantially cup shape with a cylinder 14a and a bottom 14b. On the bottom 14b, the partition 14b1 in which the liquid supply hole 20 is formed is formed above the other portion (on the side where the application body 16 is stored). Further, a concave portion 14b2 is formed on the upper surface of the partition 14b1. Specifically, a wall 14b2a is formed to surround the partition 14b1 and rise from the bottom 14b to form a cylindrical shape. The upper end of the wall 14b2a projects above the partition 14b1. An upwardly open portion surrounded by the partition 14b1 and the wall 14b2a is a concave portion 14b2. The concave portion 14b2 forms a space partitioned by the wall 14b2 on the upper surface of the bottom 14b.

  The inner diameter of the concave portion 14b2 is a size into which the application body 16 fits (see FIG. 1). As shown in FIG. 1, in a state where the application section 10 is mounted on the front shaft 14, the application body 16 is located in the recess 14b2. Therefore, when the application section 10 is mounted, the application body 16 fits into the recess 14b2. Therefore, it is possible to supply and supply the application liquid to the application body 16 while preventing the application liquid passing through the liquid supply holes 20 from leaking left and right.

In this state, the comb teeth 18d of the comb body 18 are located between the inner peripheral surface of the cylinder 14a and the outer peripheral surface of (the cylindrical wall 14b2a of) the concave portion 14b2.
The comb teeth 18d of the comb body 18 are guided by the inner peripheral surface of the cylinder 14a of the front shaft 14 and the outer peripheral surface of the concave portion 14b2 (the outer peripheral surface of the wall 14b2a) and slide between them. Therefore, the application body 16 also slides into the concave portion 14b2 and is accurately settled. Therefore, when the application part 10 is mounted on the front shaft 14, it is possible to prevent the application body 16 from being fitted and deformed.

  A flange 14c extends in the outer direction on the outer periphery of the tube 14a, and an outer locking portion 14d extends downward from the lower surface of the flange 14c in a cylindrical shape. An uneven portion 14d1 is provided on the outer peripheral surface of the locking portion 14d.

  The liquid supply hole 20 is a circular hole. Four liquid supply holes 20 are formed. The liquid supply hole 20 may be a hole other than the circular hole. The number is not limited to four, and may be one to three, five, or more.

  When the application unit 10 is mounted on the front shaft 14, the application body 16 fitted in the recess 14b2 faces the liquid supply hole 20 and faces the liquid supply hole 20, as shown in FIG. In this state, if the user shakes the application container up and down or flips the application container, the application liquid flows through the liquid supply holes 20, so that the application liquid is sufficiently supplied to the application body 16.

  More specifically, since the partition 14b1 in which the liquid supply hole 20 is formed protrudes upward (position) at the bottom 14b of the front shaft 14, the position of the lower surface of the application body 16 is lower than when the partition 14b1 does not protrude at the bottom 14b. Becomes closer to the liquid supply hole 20. Therefore, when the application container is shaken up and down or turned over, the application liquid in the main body 12 is directly supplied to the application body 16 through the liquid supply hole 20, so that a sufficient application liquid can be supplied. Further, the coating liquid can be prevented from leaking from the coating body 16 by the wall 14b2a of the concave portion 14b2.

[Body 12]
As shown in FIG. 3, the main body 12 has a substantially cup-shaped structure. The inner peripheral surface of the upper part of the main body 12 has an uneven portion 12a. When the front shaft 14 is mounted on the main body 12, the uneven portion 12a is fitted into the uneven portion 14d1 of the locking portion 14d. Therefore, the structure is such that the front shaft 14 is hard to be removed from the main body 12.

  The main body 12 has an application liquid stored in the main body 12 with its front end closed by a front shaft 14, and is sealed by the front shaft 14 and the application body 16 when not in use.

[Applying body 16]
The application body 16 can be used as long as it can impregnate the application liquid, such as a sponge, a felt, a sintered body, a continuous envelope, a natural or artificial fiber, or the like.

(Coating liquid)
The following is a detailed description of the hair dye used as the coating liquid in the embodiment.

  The hair dye contains at least one kind of acid dye, 0.3 to 2% by mass, a film forming resin, 0.5 to 6% by mass, a lower alcohol, 15 to 55% by mass, and at least 20% by mass of water. The hair dye is characterized in that the hair dye obtained by adjusting the pH to 2 to 5 contains particles having an average particle diameter of 0.3 to 3 μm.

  In particular, it is preferable that the hair dye contains at least 15 to 55% by mass of lower alcohol and 20% by mass or more of water, and the hair dye obtained by adjusting the pH to 2 to 5 impregnates the batting.

  As the acidic dye used in the present embodiment, at least one of the acidic dyes in legal dyes generally used in cosmetics can be used.

  Specific examples of the acid dye include Red No. 2, Red No. 3, Red No. 102, Red No. 104, Red No. 105, Red No. 106, Yellow No. 4, Yellow No. 5, Green No. 3, Blue No. 1, Blue No. 2, No., Red No. 201, Red No. 206, Red No. 227, Red No. 230, Red No. 231, Red No. 232, Orange No. 205, Orange No. 207, Yellow No. 202, Yellow No. 203, Green No. 201, Green No. 204, Green 205, Blue 202, Blue 203, Blue 205, Brown 201, Brown 201, Red 401, Red 502, Red 503, Red 504, Red 506, Orange 403, Yellow 402 No. 403 (1), Yellow No. 406, Yellow No. 407, Green No. 401, Green No. 402, Purple No. 401, Black No. 401, etc. (each alone or a mixture of two or more, hereinafter, same ), And the like.

  The content of these acidic dyes is desirably 0.3 to 2% by mass (hereinafter simply referred to as "%"), preferably 0.4 to 1.5%, based on the total amount of the hair dye.

  When the content of the acid dye is less than 0.3%, a sufficient hair dyeing effect cannot be obtained. On the other hand, when the content is more than 2%, the system is affected by the solubility of water and a lower alcohol in a mixed solvent. This is not preferred because the composition is likely to be unstable and to easily cause contamination on the skin and the like.

  The film-forming resin used in the present embodiment is not particularly limited as long as the film to be formed has water resistance, and examples thereof include a polymer composed of a nonionic monomer unit and / or an anionic monomer unit. Can be

  Examples of the nonionic monomer include, but are not limited to, styrene-based aromatic hydrocarbons and alkyl methacrylate-based esters. Examples of the anionic monomer include, but are not limited to, methacrylic acid, acrylic acid, and maleic acid.

  Further, the film forming resin may be a block copolymer with a polysiloxane unit (for example, polydimethylsiloxane) in order to improve water resistance and feeling. This film-forming resin is blended in order to improve secondary adhesion and water resistance.

  Preferably, a silicone resin in which a copolymer of polydimethylsiloxane and methacrylic acid and / or an ester of methacrylic acid and an aliphatic alcohol having 6 or less carbon atoms is alcohol-soluble is used.

  The content of these film-forming resins is 0.5 to 6%, preferably 1 to 3%, based on the total amount of the hair dye.

  When the content of the film-forming resin is less than 0.5%, the water resistance is insufficient, which is not preferable. On the other hand, when the content of the film-forming resin exceeds 6%, a mixed solvent of water and a lower alcohol is used. It is not preferable because it cannot be dissolved therein or the texture after applying the hair deteriorates.

  As the lower alcohol used in the present embodiment, for example, one or more kinds of volatile lower alcohols such as ethanol, propanol, butanol, isopropanol, and isobutanol can be used. Among lower alcohols, ethanol is desirable from the viewpoint of safety, drying properties, smell and the like.

  The content of these lower alcohols is 15 to 55%, preferably 30 to 50%, based on the total amount of the hair dye.

  When the content of the lower alcohol is less than 15%, the drying property of the hair dye is lowered, which is not preferable. On the other hand, when the content is more than 55%, the cumulative hair dyeing effect is lowered, which is not preferable.

  The balance of the hair dye in the present embodiment is adjusted with water (purified water, distilled water, ion-exchanged water, pure water, tap water, etc.).

  The content of this water needs to be 20% or more based on the total amount of the hair dye, and more preferably 30 to 50%.

  When the content of water is less than 20%, the solubility of the dye is reduced and the hair dyeing effect is also reduced, which is not preferable. On the other hand, when the content is more than 50%, the stability of the contained water-resistant film-forming resin is increased. May slightly decrease, and the drying property may slightly decrease.

  The particles having an average particle diameter of 0.3 to 3 μm used in the present embodiment are used for improving the temporary coloring property of gray hair immediately after application. In the present embodiment, the “average particle diameter” refers to a particle weight analyzer FPAR-1000 (manufactured by Otsuka Electronics Co., Ltd.) and a particle size distribution analyzer Microtrac SIA (Microtrac Bell Co., Ltd.) Manufactured).

  Examples of the particles used in the present embodiment include black iron oxide, yellow iron oxide, iron oxide such as red iron oxide, inorganic particles such as carbon black, titanium oxide, and zinc oxide, and pigments such as black ink, silica, ultramarine blue, mica, and talc. There is no problem if it is a particle. However, iron oxides such as black iron oxide, yellow iron oxide, and red iron oxide, and inorganic pigment particles such as carbon black are preferable in terms of hiding power and cost.

  In the hair dye of the present embodiment, as described later, the pH of the hair dye is designed to be as low as 2 to 5 in order to improve the hair dyeability by the acid dye. The particles having an average particle diameter of 0.3 to 3 μm used for this effect do not impair the effect of the present embodiment, but partially deteriorate in time and the color tone is slightly changed. Was in As a result of further intensive studies on this point, it is preferable that the average particle diameter is 0.3 to 3 μm so that the particles can be easily dispersed even in a mixed solvent of water and a lower alcohol, and that the influence of pH is not further affected. It is desirable to use particles whose surface has been subjected to a silica treatment.

  In the present embodiment, the silica-treated particles are produced by spray-drying black iron oxide, yellow iron oxide, iron oxide such as red iron oxide, carbon black, inorganic particles such as titanium oxide, and particles such as black. Alternatively, it can be obtained by surface treatment by a vapor deposition method or the like, and if there is a commercial product, it can also be used.

  The treatment concentration of silica applied to the surface of these particles is 2 to 15%, preferably 2 to 12% in terms of mass before and after the treatment.

  If the treatment concentration of the silica is less than 2%, the treatment amount is insufficient and the particles may be deteriorated or caked with the passage of time. On the other hand, if the treatment concentration exceeds 15%, the hue of the particles themselves may be obtained. Effect may be reduced and the temporary hair dyeing properties may be slightly reduced.

  The average particle diameter of the particles or the silica-treated particles in the present embodiment is approximately 0.3 to 3 μm, and preferably 0.5 to 2 μm.

  When the average particle diameter of these particles is less than 0.3 μm, it is difficult from the viewpoint of manufacturing technology and cost. In that case, the production of silica-treated particles is technically difficult, and is not suitable for use due to cost problems. On the other hand, when the average particle diameter exceeds 3 μm, particles adhering to the hair are easily peeled off when combing the hair with a comb, which is not preferable.

  The content of the particles having an average particle diameter of 0.3 to 3 μm in the present embodiment is 0.5 to 5%, preferably 1 to 3%, based on the total amount of the hair dye.

  When the content of these particles is less than 0.5%, the temporary coloring property is insufficient. On the other hand, when the content is more than 5%, the treatment concentration of silica, the feeling in use and the feeling are deteriorated, which is not preferable.

  As a sedimentation inhibitor for the particles used in the present embodiment, a thickener may be contained, and examples thereof include hydroxyethyl cellulose, xanthan gum, gellan gum, guar gum, hydroxypropyl guar gum, sclerotium gum, carbomer, and the like (acryloyl dimethyl taurine). Ammonium / beheneth methacrylate-25) crosspolymer, and among them, (acryloyldimethyltaurin ammonium / beheneth-25 methacrylate) crosspolymer is preferred from the viewpoint of fat solubility in a low pH region and stable thickening. It is suitable.

  The content of the thickener in the present embodiment is 1.5 to 3%, preferably 1.8 to 2.5%, based on the total amount of the hair dye.

  When the content of this thickener is less than 1.5%, the effect of suppressing sedimentation of the particles is insufficient, which is not preferable. On the other hand, when it exceeds 3%, the hair dye is solidified in a gel state. Is not preferred in terms of usability.

  The hair dye of the present embodiment preferably contains a hair dyeing aid from the viewpoint of further exhibiting the hair dyeing effect.

  Examples of the hair dyeing assistant that can be used include, for example, at least one kind of benzyl alcohol, phenylethyl alcohol, phenoxyethanol, propylene carbonate, propylene glycol, ethoxydiglycol, N-methylpyrrolidone, N-methyl-2-pyrrolidone, and the like. Is mentioned.

  The content of these hair dye assistants is preferably 2 to 20%, and more preferably 5 to 15%, based on the total amount of the hair dye.

  When the content of the hair dyeing aid is less than 2%, the hair dyeing effect is still insufficient. On the other hand, when the content exceeds 20%, the drying property after application of the hair coloring material is reduced, and the hair dyeing agent is applied to clothes and the like. It is not preferable because the risk of color transfer increases.

  The hair dye of the present embodiment needs to adjust the pH to 2 to 5 in order to improve coloring property, prevent skin irritation, and prevent skin dyeing trouble, and preferably the pH is 2.5 to 4.0. It is desirable to adjust to.

  When the pH of the hair dye is less than 2, the skin dyeing property increases, which is not preferable. On the other hand, when the pH exceeds 5, the hair dyeing property decreases, which is not preferable.

  In the present embodiment, the pH is adjusted using an organic acid such as formic acid, acetic acid, lactic acid, tartaric acid, malic acid, citric acid, or a glycolic acid or an inorganic acid or a salt thereof, and in some cases, an alkali such as triethanolamine. be able to.

  The hair dye of the present embodiment includes, in addition to at least one of the above-mentioned acid dyes, a film-forming resin, a lower alcohol, water, and particles having an average particle diameter of 0.3 to 3 μm, a range that does not impair the effects of the present embodiment. In addition, other raw materials, for example, various surfactants, preservatives, ultraviolet absorbers, antioxidants, antioxidants, chelating agents, oily components, flavors, plant and animal extracts, and the like can be appropriately contained.

  The hair dye of the present embodiment can be prepared by a conventional method, and contains at least one kind of the above-mentioned acid dye, a film-forming resin, a lower alcohol, water, and components such as particles having an average particle diameter of 0.3 to 3 μm. It can be manufactured by blending in the above content ranges and uniformly stirring and mixing.

  For example, a film-forming resin, an alcohol phase such as a lower alcohol, and an aqueous phase such as an acid dye and water are each stirred with a general-purpose disperser or the like until uniform, and then the alcohol phase and the aqueous phase are mixed. Add a pH adjuster, a thickener, etc., stir until uniform with a disper, etc., add particles with an average particle size of 0.3-3 μm, stir with a homomixer, etc. to prepare a hair dye can do.

  In providing the hair dye of the present embodiment configured as described above for use, a general-purpose hair applicator can be used, and the shape, structure, and the like of the hair dye container to be used are not particularly limited. Applicators having a knock-type valve device, mascara-type applicators, tube-type applicators, and applicators having a piston pressing mechanism.

  The hair dye of the present embodiment configured as described above has at least one kind of an acid dye of 0.3 to 2%, a film-forming resin of 0.5 to 6%, a lower alcohol of 15 to 55%, and water of 20% or more. In a hair dye obtained by adjusting the pH to 2 to 5 at least, by including particles having an average particle diameter of 0.3 to 3 μm, particles such as a pigment can be stably dispersed even in a low pH environment, It is not necessary to wash the hair immediately after use, and it not only has excellent hair dyeing properties immediately after application, but also has excellent cumulative hair dyeing properties that gradually dyes the hair as it is used more times. There is no deviation from the hue during cumulative hair dyeing, and a hair dye excellent in water resistance and usability can be obtained.

  According to the coating container of the first embodiment, when the coating unit 10 is mounted on the front shaft 14 of the main body 12, the liquid supply hole 20 faces the coating body 16. When the user turns the application container in the state shown in FIG. 1 upside down (U direction, D direction) (reverses the state shown in FIG. 1), the application liquid flows downward by gravity. The coating liquid flows into the coating body 16 through the liquid supply hole 20, and the coating liquid impregnates the coating body 16. Thus, the application liquid is supplied to the application body 16 through the liquid supply hole 20. If it can be determined that the coating liquid has been impregnated to some extent or sufficiently, the top and bottom of the coating container are returned to the original. Alternatively, the application container is easily made to flow into the application body 16 by swinging up and down.

  In this state, the user appropriately grasps the cap 22 and removes the application unit 10 from the front shaft 14. Then, the user holds the cap 22 and strokes the application body 16 on the hair while combing the hair with the comb body 18. The hair is applied to the hair by the application unit 10.

  Therefore, the user can apply the application liquid from the application body 16 to the hair. When the amount of the application liquid on the application body 16 becomes small, the application section 10 is mounted on the (main shaft 14) of the main body 12, and the container is shaken up and down or inverted again, so that the application inside the main body 12 is performed. The liquid is supplied to the application body 16 through the liquid supply hole 20.

  When the application unit 10 is mounted on the front shaft 14, the application body 16 comes into contact with the liquid supply hole 20. Therefore, the liquid supply hole 20 is closed and the coating liquid hardly flows out from the coating body 16, so that liquid leakage can be prevented. Further, when the user has used up the application liquid in the application unit 10, the application unit 10 can be refilled into the application body 16 by attaching the application unit 10 to the main body 12 and closing the cap 22 again.

  In the application container of the embodiment, when compared with an application body (a mascara or the like) provided with a brush body at the tip of the shaft-shaped portion, the application container of the embodiment can cover a wide area by removing the application unit 10 (detachment of the cap 22). Can be applied to match.

  The application body 16 is a porous application body such as a sponge. Therefore, the amount of application to the application body 16 at one time is larger than that of the brush body, so that a troublesome pouring operation can be omitted.

  Further, the brush body needs a certain viscosity to hold the application liquid. On the other hand, in the application unit 10 of the embodiment, since the application body 16 can be selected from materials such as sponge, felt, sintered body, and continuous air-package body, a liquid having a low viscosity can be used. Performance such as drying property can be improved.

The coating container according to the second embodiment is described below with reference to the drawings.
FIG. 5 is an overall explanatory view of an application container according to a second embodiment of the present invention, and FIG. 6 is a component explanatory view of a main body provided with a front shaft in the application container of FIG. 5 and 6 are the same as those in the first embodiment with the same reference numerals.
As shown in FIGS. 5 and 6, the front shaft 14A has a different configuration from the front shaft of the first embodiment. More specifically, in the main coating container of FIG. 1, the front shaft 14A has a substantially flat bottom 14b formed at the lower portion of the cylinder 14a. The front shaft 14A has a substantially cup shape with the cylinder 14a and the bottom 14b.

  The bottom surface of the bottom 14b is substantially flat. Specifically, as shown in FIG. 5, the lower surface of the bottom 14b has the partition 14b1 in which the liquid supply hole 20 is formed at the same position in the vertical direction as the periphery thereof. The partition 14b1 of the bottom 14b is a concave portion 14b2 whose periphery is formed by a cylindrical wall (14b2a). A low cylindrical wall 24 protrudes upward from the partition 14b1 on the side of the application body 16 facing the storage side of the application body 16 surrounding the liquid supply hole 20. As shown in FIG. 5, a space 26 is formed between the upper surface of the bottom 14 b and the application body 16. The space 26 allows the application liquid to be held to some extent in the space 26 and increases the area where the application liquid comes into contact with the application body 16 as compared with the case of close contact as in the first embodiment of FIG.

When the application container is mounted and the application container is mounted, if the application container is shaken up and down or turned upside down, the application liquid flows into the space 26, so that the application body 16 can be sufficiently impregnated with the application body. . Further, a space 26 around the wall 24 on the upper surface of the bottom 14b serves as a reservoir for the coating liquid. The pooling liquid accumulates the application liquid, so that the excess liquid does not fall into the main body 12.
In the second embodiment, the other configurations and operational effects are the same as those in the first embodiment.

The application container according to the third embodiment is described below with reference to the drawings.
FIG. 7 is an overall explanatory diagram of the coating container according to the third embodiment. FIG. 7 shows the same parts as in the first embodiment with the same reference numerals.
As shown in FIG. 7, the coating container according to the third embodiment is different from the first and second embodiments in that a relay core 28 is provided in the main body 12A, and the tip shaft 14B is also a tip of the first embodiment. The configuration is different from the axis.

  More specifically, as shown in FIG. 7, in the front shaft 14B, the bottom 14b of the front shaft 14B does not have the partition 14b1 used in the first embodiment or the second embodiment, and instead has an opening 14e in the center. It is formed. There is no partition 14b1, but there is a cylindrical wall 14b2a. The opening 14e is surrounded by a cylindrical wall 14b2a from the periphery.

The main body 12A has a columnar relay core 28 mounted therein. The main body 12A includes a cylindrical support portion 12b therein. The support portion 12b supports the relay core 28 in a state where the relay core 28 is fitted therein. The relay core 28 has its upper end facing the opening 14e formed in the bottom 14b of the front shaft 14B. When the application unit 10 is mounted on the front shaft 14B, the relay core 28 comes into contact with the application body 16. The coating liquid in the main body 12 is supplied to the coating body 16 via the relay core 28.
Therefore, a sufficient application liquid can be supplied to the application body 16 via the relay core 28 without shaking the application container up and down or inverting.
Further, the application part 10 can be rapidly filled with the application liquid that has been exuded by crushing (squeezing) the relay core 28 to some extent, for example, about several mm by the application body 16 when the application part 10 is mounted on the front shaft 14B.

The relay core 28 is preferably made of a material capable of relaying a coating liquid such as sponge, felt, sintered body, continuous air-pack, natural or artificial fiber, or the like. Preferably, the capillary force of the relay core 28 is lower than that of the coating body 16.
In the third embodiment, the other configurations and functions and effects described above are the same as those in the first embodiment.

However, in the fourth embodiment, there is no relay core 28 of the third embodiment, and the application body 16A is larger than that of the first to third embodiments, and extends inside the main body 12.
Specifically, the application body 16 has a structure in which the extended end protrudes inward from the main body 12 beyond the end of the comb teeth 18d of the comb body 18 through the opening 14e. In this case, the application body 16 faces (or faces) the inside of the main body 12 so as to close the opening 14e.

  According to the coating container of the fourth embodiment, the tip of the coating body 16 protrudes inward of the main body 12 from the tip of the comb teeth 18d of the comb body 18 through the opening 14e. When the application section 10 is mounted on the main body 12, the application body 16 directly faces the inside of the main body 12. If the application container is shaken up and down or inverted, the application liquid easily flows around the application body 16, and the application liquid sufficiently touches the application body 16, so that the application body 16 is surely impregnated with the application liquid. be able to.

When the application section 10 is removed from the main body 12 and used for application, since the end face of the application body 16 projects beyond the end face of the comb teeth 18d of the comb body 18, the application body 16 is applied to the hair or the like at the time of application. Pressing has the effect of squeezing the liquid out of the application body 16. The application body 16 can control the squeezing amount of the application liquid by adjusting the intensity of the pressing pressure. Further, the liquid amount of the application body 16 can be controlled by controlling and adjusting the size of the application body 16 protruding from the comb teeth 18d.
In the fourth embodiment, the other configurations and functions and effects described above are the same as those in the first embodiment.

  The coating container of the present invention can be used for cosmetic containers such as hair dyeing containers.
