  As described above, Patent Documents 1 to 3 disclose coating-type aerosol products, but various problems may occur particularly when used as an aerosol product for a human body that is used by being pressed against the human body. That is, since the application member 102 of Patent Document 1 is provided so that the central passage 108 passes through the axis of the stem 107, the discharged content (aerosol composition 100) directly adheres to the human skin. However, there is a problem that the cooling is excessively strong and in some cases, the cooling damage is felt.

  Moreover, although the application body 201 of patent document 2 is comprised so that a chemical | medical agent may be apply | coated through the sintered porous body 204, the content impregnated by the sintered porous body 204 reaches | attains the skin surface. The movement is slow and the cooling feels weak.

  The application means (sponge 305) of Patent Document 3 is a sponge, so that even if it is cooled by liquefied gas, it is immediately released to the outside and the cooling effect does not last.

  Then, in view of such a problem, an object of the present invention is to provide an aerosol product that is excellent in cooling performance such as a duration of a cooling effect in an aerosol product that is used by being directly pressed against a human body.

  The aerosol product of the present invention includes an aerosol container filled with a content containing a liquefied gas, and the contents in the aerosol container when the aerosol container is attached to the aerosol container and operated to discharge the content. An aerosol product comprising a cooling device that is capable of discharging an object and that cools the human body by being pressed against the human body, wherein the cooling device temporarily discharges the contents discharged from the aerosol container by the operation of the aerosol product. Holding internal space, a communication path formed between the internal space and the outside of the cooling tool, a metal cooling plate provided on the outer surface side of the cooling tool, and the cooling plate A non-metallic partition wall provided between the inner space, the communication path is provided on the outer periphery from the center axis of the aerosol container, and the liquefied gas is vaporized, whereby the cooling plate is Characterized in that it retirement.

  The cooling tool is mounted on the aerosol container, and a main body having a central passage provided between the aerosol container inside and the internal space along the central axis of the aerosol container, and mounted on the main body And a cooling part that forms the internal space together with the main body part, and the cooling part includes a non-metallic base part that is attached to the main body part and includes the non-metallic partition wall. It is preferable that a concave portion that forms an internal space and that extends in the outer peripheral direction with respect to the central passage is formed, and an end portion on the internal space side of the communication passage is disposed on the outer peripheral side of the concave portion.

  Further, the cooling plate is formed in a convex shape that is convex toward the side opposite to the base portion, and the top of the convex cooling plate protrudes from the end portion on the outlet side of the communication path. It is preferable to be formed as follows.

  Moreover, it is preferable that the said communicating path is formed as a channel | path formed through the said partition and the said cooling plate.

  Moreover, it is preferable that the said communication path is formed so that the edge part by the side of the exit of the said communication path may be arrange | positioned in the position along the outer periphery of the said cooling plate.

  Moreover, it is preferable that the said communicating path is a some communicating hole provided cyclically | annularly.

  According to the present invention, the cooling tool temporarily holds the contents discharged from the aerosol container by the operation of the aerosol product, and the communication path formed between the inner space and the outside of the cooling tool. And a metal cooling plate provided on the outer surface side of the cooling tool, and a non-metallic partition wall provided between the cooling plate and the internal space, the communication path from the central axis of the aerosol container Since the liquefied gas is vaporized and the cooling plate is cooled by being provided on the outer periphery, the vaporization heat of the liquefied gas is easily transmitted to the cooling plate by the metal cooling plate when the liquefied gas is vaporized. Therefore, by using a metal cooling plate, it is possible to strongly cool the cooling plate used by being pressed against the human body. Further, since a non-metallic partition wall is provided between the cooling plate and the internal space, heat from the human skin is difficult to transfer to the contents in the internal space. Therefore, the temperature in the internal space cooled by the liquefied gas moved from the aerosol container to the internal space is unlikely to rise, and the liquefied gas in the contents is slowly vaporized, and the cooling effect is sustained. Furthermore, since the communication path is provided on the outer periphery from the central axis of the aerosol container, the contents discharged from the aerosol container are not directly concentrated on the skin and adhered to one point, thereby preventing overcooling of the skin. Can do.

  In addition, a cooling tool is mounted on the aerosol container and has a main body portion having a central passage provided between the aerosol container inside and the internal space along the central axis of the aerosol container, and is mounted on the main body section. And a cooling part that forms an internal space, and the cooling part is attached to the main body part, and includes a non-metallic base including a non-metallic partition wall, and forms an internal space in the base, with respect to the central passage In the case where a recessed portion extending in the outer peripheral direction is formed and the end portion on the inner space side of the communication passage is disposed on the outer peripheral side of the recessed portion, the content supplied from the central passage of the main body portion is the inner space. If it reaches | attains, it will move toward the edge part by the side of the internal space of the communicating path arrange | positioned at the outer peripheral side of internal space. Therefore, the liquefied gas in the contents moves from the center in the internal space toward the outer peripheral side, the liquefied gas spreads over the entire internal space, and the entire recess can be cooled.

  Further, the cooling plate is formed in a convex shape that is convex toward the side opposite to the base, and the top of the convex cooling plate is formed so as to protrude from the end on the outlet side of the communication path. In this case, since the vaporized liquefied gas is discharged from the end portion on the outlet side of the communication path, the cooling plate is cooled from the end portion on the outlet side of the communication path toward the top of the cooling plate. Therefore, since it cools toward the center from the outer peripheral side of a cooling plate, since the top part of the cooling plate which contacts a human body's skin directly is hard to be overcooled, the pain by overcooling is not felt. In addition, since the top of the cooling plate is located at a position protruding from the end on the outlet side of the communication path, when the cooling plate is pressed against the skin of the human body, the end on the outlet side of the communication path is Cannot be blocked by skin. Therefore, it is difficult for the skin to be supercooled, and the contents can be continuously discharged from the aerosol container while the cooling plate is pressed against the human skin.

  Further, when the communication passage is formed as a passage formed through the partition wall and the cooling plate, the cooling plate can be efficiently cooled. Moreover, when the content contains an active ingredient to be applied to the skin of the human body, the discharged material discharged from the communication path is easily applied to the skin by the cooling plate.

  When the communication path is formed so that the end of the communication path on the outlet side is disposed at a position along the outer peripheral edge of the cooling plate, the cooling plate is cooled from the outer peripheral side toward the center. It is easy to do and can prevent overcooling of the skin more.

  Further, when the communication path is a plurality of communication holes provided in an annular shape, the cooling plate can be uniformly cooled from the outer peripheral side toward the center.

  Hereinafter, an aerosol product of the present invention will be described in detail with reference to the accompanying drawings.

Embodiment 1
The aerosol product 1 shown in FIG. 1 (a) is an aerosol container 2 filled with a content A containing a liquefied gas, and when the aerosol product 1 is attached to the aerosol container 2 and operated to discharge the content A. And a cooling tool 3 that is capable of discharging the contents A in the aerosol container 2 and that cools the human body by being pressed against the human body.

  As the aerosol container 2, a known pressure-resistant container can be used, and a bottom part and a body part are formed by impact processing or squeezing and ironing a metal plate such as aluminum or tinplate or a disk-shaped slag, and further necking processing and curling processing are performed. Thus, the shoulder portion and the bead portion 2a are formed. In addition, a three-piece can or a two-piece can in which a bottom portion and a metal having a bead portion 2a are fixed to a barrel portion made of a metal plate such as a tin plate or a tin-nickel steel plate by double winding. May be used. Furthermore, other materials having pressure resistance such as pressure resistant glass and synthetic resin may be used.

  Moreover, the aerosol container 2 is provided with the aerosol valve | bulb 21, as FIG. 1 (a) shows. The aerosol valve 21 is not limited to the illustrated structure, and other known structures can be used. In the structure shown in FIG. 1A, the aerosol valve 21 is a bead portion of the aerosol container 2. 2a, a mounting cup 21a fixed via a gasket, a housing 21b held at the center of the mounting cup 21a, a stem 21d accommodated in the housing 21b together with a spring 21c and constantly biased upward by the spring 21c The inner diameter surface of the stem 21d is inserted, and the stem 21d is urged upward by the repulsive force of the spring 21c so as to cover the stem hole of the stem 21d or cover the entire outer peripheral surface below the stem hole. And a stem rubber 21e for sealing. The aerosol valve 21 is a push-down type in which the stem hole is opened by moving the stem 21d below the axis of the aerosol container 2 in FIG. 1A, and the aerosol product 1 is used in an inverted state. A dip tube is not attached to the housing 21b. Although the structure of the cooling tool 3 will be described later, as shown in FIG. 1A, the cooling tool 3 is attached to the aerosol container 2 via a stem 21d, and the entire cooling tool 3 is connected to the stem 21d. The content A is discharged through the stem hole.

  As shown in FIG. 1A, the shoulder cover 4 is attached to the aerosol container 2 and covers the outer periphery of the aerosol valve 21 to protect the aerosol valve 21. A cap (not shown) can be attached to the upper portion of the shoulder cover 4 in the figure, and the aerosol product 1 is prevented from being erroneously operated when not in use.

  The content A (aerosol composition) filled in the aerosol container 2 contains a liquefied gas that produces a cooling effect when vaporized. The liquefied gas also acts as a propellant for the content A and also as a self-cooling component that cools the content A itself released from the aerosol container 2. A liquefied gas having a boiling point of 5 ° C. or less is preferred from the viewpoint of excellent cooling effect. For example, liquefied petroleum gas comprising propane, normal butane, isobutane and a mixture thereof, dimethyl ether, trans-1,3,3 , 3-tetrafluoroprop-1-ene (HFO-1234ze), trans-2,3,3,3-tetrafluoroprop-1-ene (HFO-1234yf) and the like, and mixtures thereof can give. Further, hydrocarbons having a boiling point of 5 to 40 ° C. such as normal pentane and isopentane may be blended in order to adjust the cooling temperature and duration. The vapor pressure of the liquefied gas is not particularly limited, but after the liquefied gas is discharged and vaporized, the liquefied gas tends to remain and has an excellent cooling effect. For example, the vapor pressure at 20 ° C. is 0.05. It is preferable to use a liquefied gas of ~ 0.4 (MPa), more preferably 0.08 to 0.3 (MPa).

  Although the compounding quantity of liquefied gas will not be specifically limited if the cooling plate 35 mentioned later can be cooled, For example, in the content A, 40-99 mass%, Furthermore, 60-98.5 mass%, Especially 70-98. It is preferable that it is mass%. When the blending amount of the liquefied gas is smaller than 40% by mass, the self-cooling capacity is insufficient, and the liquefied gas is not easily left in the discharged contents, and the cooling effect tends to be weak. On the other hand, when the blending amount of the liquefied gas is larger than 99% by mass, the liquefied gas is rapidly vaporized and it is difficult to maintain the cooling effect.

  The content A may contain a stock solution containing an active ingredient in addition to the liquefied gas. The active ingredient can be appropriately selected according to the use and purpose of the product. For example, anti-inflammatory analgesics such as methyl salicylate, ketoprofen, indomethacin, felbinac; miconazole nitrate, econazole, bifonazole, clotrimazole, neticonazole hydrochloride, Antifungal agents such as sulconazole nitrate, oxyconazole nitrate, terbinafine hydrochloride, butenafine hydrochloride; urea, lidocaine, dibucaine, procaine, dibucaine hydrochloride, lidocaine hydrochloride, procaine hydrochloride, ethyl aminobenzoate, oxypolyentoxide decane, diphenylpyraline hydrochloride, Antipruritics such as diphenhydramine hydrochloride, chlorpheniramine, diphenhydramine salicylate, crotamiton; N, N-diethyl-m-toluamide (diet), diethylacaprylate Pest repellents such as para; benzoic acid ester, sodium benzoate, potassium sorbate, phenoxyethanol, benzalkonium chloride, benzethonium chloride, chlorhexidine chloride, photosensitizer, parachlormetacresol, etc .; chili pepper tincture, dicaprylic acid Blood circulation promoters such as pyridoxine, assembly extract, acetic acid-dl-α-tocopherol; refreshing agents such as l-menthol and camphor; astringents such as allantoin hydroxyaluminum, citric acid, lactic acid and tannic acid; allantoin, glycyrrhetic acid, Anti-inflammatory agents such as azulene; deodorants such as lauric acid methacrylate, methyl benzoate, methyl phenylacetate, geranyl crotolate, acetophenone myristate, benzyl acetate, benzyl propionate; Antiperspirants such as droxyaluminum; amino acids such as glycine, alanine, leucine, isoleucine, serine, threonine tryptophan, cystine, cysteine, aspartic acid, glutamic acid; retinol, retinol palmitate, pyridoxine chloride, benzyl nicotinate, nicotinamide Vitamins such as nicotinic acid dl-α-tocopherol, vitamin D2 (ergocaciferol), dl-α-tocopherol, dl-α-tocopherol acetate, pantothenic acid, biotin; α-tocopherol, dibutylhydroxytoluene, butylhydroxyanisole Antioxidants such as: Dokudami extract, Oat extract, Peonies extract, Loofah extract, Kina extract, Primrose extract, Rose extract, Lemon extract, Aloe extract, Shii Ubu root extract, eucalyptus extract, sage extract, tea extract, seaweed extract, placenta extract, extract, such as silk extract; synthetic perfumes, fragrances such as natural flavors; and the like.

  The active ingredient may be directly dissolved in the liquefied gas, but it is preferable to dissolve the active ingredient in the solvent from the viewpoint that the cooling effect is easily maintained. In this case, the blending amount is preferably 0.1 to 50% by mass, more preferably 0.5 to 40% by mass in the stock solution. When the amount of the active ingredient is less than 0.1% by mass, the concentration of the active ingredient is low, and the amount used is increased in order to obtain a desired effect. When the amount exceeds 50% by mass, the cooling effect by the solvent is weakened. Tend.

  The solvent not only dissolves or disperses the active ingredient, but when released from the aerosol container 2, the solvent is cooled by vaporization of the liquefied gas and maintains the cooling effect. Examples of the solvent include water such as purified water, ion-exchanged water, physiological saline, and deep sea water; monovalent lower alcohols such as ethanol and isopropanol; ethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin, And polyhydric alcohols such as diethylene glycol.

  Although the compounding quantity of a solvent is not specifically limited, It is preferable that it is 50-99.9 mass% in an undiluted | stock solution, Furthermore, it is preferable that it is 60-99.5 mass%. When the blending amount of the solvent is less than 50% by mass, the cooling effect is hardly sustained, and when it exceeds 99.9% by mass, it becomes difficult to blend the necessary amount of the active ingredient and the amount of use at one time increases.

  The stock solution may contain an oily component, a surfactant, an auxiliary component, etc. in addition to the active ingredient and the solvent.

  The oily component is used for the purpose of facilitating the attachment of the active ingredient, improving the feeling of use such as obtaining a dry feel, moisturizing the skin, and making it difficult to dry. Examples of the oil component include silicone oils such as octamethyltrisiloxane, decamethyltetrasiloxane, methylpolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and methylphenylpolysiloxane; myristic acid Ester oil such as isopropyl, cetyl octanoate, octyldodecyl myristate, isopropyl palmitate, diethyl phthalate, diethoxyethyl phthalate, diethoxyethyl succinate, diethyl sebacate; carbonization such as squalane, squalene, liquid paraffin, isoparaffin Hydrogen oil: lauryl alcohol, cetyl alcohol, stearyl alcohol, myristyl alcohol, oleyl alcohol, isostearyl alcohol Higher alcohols such as lauric acid, myristic acid, palmitic acid, stearic acid, and oleic acid; waxes such as beeswax, lanolin, candelilla wax, paraffin wax; camellia oil, corn oil, olive oil, castor oil And oils such as safflower oil, jojoba oil, and coconut oil.

  When blending the oil component, the blending amount is preferably 0.1 to 10% by mass, more preferably 0.5 to 5% by mass in the stock solution. When the blending amount of the oil component is less than 0.1% by mass, it is difficult to obtain the effect of blending the oil component, and when it exceeds 10% by mass, the sticky feeling becomes stronger and the drying property becomes worse. Cheap.

  The surfactant is used for the purpose of solubilizing an active ingredient that is difficult to dissolve in a solvent, or facilitating the attachment of the active ingredient. Examples of the surfactant include sorbitan fatty acid ester, glycerin fatty acid ester, poly (di, tri, tetra, penta, hexa, deca, etc.) glycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyethylene Glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene castor oil / hardened castor oil, polyoxyethylene lanolin alcohol, polyoxyethylene alkylamine, polyoxyethylene fatty acid amide, fatty acid alkylol Amides, alkylpolyglucosides, polyoxyethylene / methylpolysiloxane copolymers, polyoxypropylene / methylpolysiloxane copolymers Coalescence, poly nonionic surface active agents, such as (oxyethylene-oxypropylene) methylpolysiloxane copolymer, and the like.

  When the surfactant is blended, the blending amount is preferably 0.1 to 10% by mass, more preferably 0.5 to 5% by mass in the stock solution. When the blending amount of the surfactant is less than 0.1% by mass, it is difficult to obtain the effect of blending the surfactant. The feeling of use tends to decrease.

  Examples of the auxiliary component include a pH adjuster for adjusting the pH of the stock solution to dissolve the active ingredient stably, and a thickener for adjusting the cooling effect by imparting viscosity to the stock solution.

  Examples of the pH adjuster include triethanolamine (TEA), diethanolamine (DEA), monoethanolamine (MEA), diisopropanolamine (DIPA), 2-amino-2-methyl-1-propanol (AMP), 2 -Organic alkalis such as amino-2-methyl-1,3-propanediol (AMPD), inorganic alkalis such as potassium hydroxide, sodium hydroxide and ammonium hydroxide, organics such as citric acid, glycolic acid, lactic acid and phosphoric acid Examples thereof include inorganic acids such as acid and hydrochloric acid.

  Examples of the thickener include agar, dextrin, pectin, starch, gelatin, gelatin hydrolyzate, sodium alginate, methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, nitrulose, crystalline cellulose, xanthan gum, gellan gum, modified potato starch , Polyvinyl alcohol, polyvinyl pyrrolidone, carboxyvinyl polymer and the like.

  When blending the thickener, the blending amount is preferably 0.01 to 5 mass%, more preferably 0.1 to 3 mass% in the stock solution. When the blending amount of the thickener is less than 0.01% by mass, the viscosity increase is small and it is difficult to obtain the blending effect of the thickener, and when it exceeds 5% by mass, the viscosity becomes too high. The contents A discharged in the step are likely to stay and the immediate effect is deteriorated.

  The stock solution can be prepared by dissolving or dispersing (emulsifying) the active ingredient in a solvent, but it does not separate even if the liquefied gas gradually evaporates in the internal space 33 and can be applied to the skin with a uniform composition. In view of this, a uniform product in which the active ingredient is dissolved in a solvent is preferable.

  The stock solution is preferably 1 to 60% by mass, more preferably 1.5 to 40% by mass, and particularly preferably 2 to 30% by mass in the content A. When the blending amount of the undiluted solution is less than 1% by mass, the cooling effect is hardly sustained, and when it exceeds 60% by mass, it is difficult to obtain a cooling feeling and the undiluted solution tends to remain in the internal space 33, so that the usability is poor.

  The contents A can be prepared by filling the aerosol container 2 with the stock solution and filling the liquefied gas by undercup filling when the aerosol valve 21 is fixed to the opening of the aerosol container 2. The liquefied gas may be filled from the stem 21d after the aerosol valve 21 is fixed. In the content A obtained, the stock solution and the liquefied gas were uniformly dissolved so that the stock solution and the liquefied gas could be applied with a uniform composition without separating even if the liquefied gas gradually vaporized in the internal space 33. Those are preferred.

  Next, the cooling tool 3 of this embodiment is demonstrated. As shown in FIG. 1A, the cooling tool 3 is attached to the aerosol container 2 and has a main body 31 having a central passage 31 a provided along the central axis of the aerosol container 2, and the main body 31. And a cooling part 32 that forms an internal space 33 together with the main body part 31. If each part of the main body 31 has a shape capable of moving the content A discharged from the aerosol container 2 through the stem hole to the internal space 33 and mounting the cooling unit 32, the shape is Although not particularly limited, in the present embodiment, the main body 31 includes a cylindrical stem mounting portion 31b whose one end is attached to the end of the stem 21d, and an outer peripheral direction of the aerosol container 2 from the other end of the stem mounting portion 31b. A flat plate portion 31c extending and a side portion 31d extending from the outer periphery of the flat plate portion 31c in the same direction as the stem mounting portion 31b are provided. A step portion 31e for attaching the cooling portion 32 is formed on the side portion 31d, and the cooling portion 32 is fitted into the step portion 31e from the outside. A central passage 31a communicating with the passage in the stem 21d is formed in the stem mounting portion 31b, and the central passage 31a is provided between the aerosol container 2 and the internal space 33. By operating the aerosol product 1, the content A discharged from the stem hole is moved to the internal space 33 through the central passage 31 a.

  The cooling unit 32 further includes a communication path 34 formed between the internal space 33 and the outside of the cooling tool 3, a metal cooling plate 35 provided on the outer surface side of the cooling tool 3, A non-metallic partition wall 36 a provided between the internal space 33 and the inner space 33 is provided. More specifically, the cooling unit 32 includes a non-metallic base portion 36 that is attached to the main body portion 31 and includes a non-metallic partition wall 36 a, and the base portion 36 has a central passage for forming the internal space 33. A recess 36b that extends in the outer peripheral direction with respect to 31a is formed. The internal space 33 is a part that temporarily holds the content A discharged from the aerosol container 2 by the operation of the aerosol product 1 and extends in a direction perpendicular to the central passage 31a by the recess 36b. In the present embodiment, as shown in FIG. 1A, the inner space side end of the communication path 34 is disposed on the outer peripheral side of the recess 36b. The content A that has moved into the internal space 33 formed by the recessed portion 36b of the base portion 36 and the flat plate portion 31c of the main body portion 31 will be described in detail later, but the communication passage 34 from the center in the internal space 33 to the outer peripheral side will be described later. , And vaporizes through the communication passage 34 and is discharged to the outside of the cooling tool 3 to cool the cooling plate 35 by heat of vaporization.

  The metal cooling plate 35 is a part that is pressed against the skin of the human body and cools the skin pressed by the cooling plate 35. In addition, the cooling plate 35 can be used also for apply | coating the discharge material by which the content A was discharged outside, when the content A contains an active ingredient. The cooling plate 35 is cooled by the heat generated by vaporization of the liquefied gas in the contents A discharged from the communication passage 34, so that the portion around the communication passage 34 is cooled, and the cooling plate 35 is pressed against the human body from the periphery of the communication passage 34. Transfers heat to the center of the body to cool the human body. By using the metal cooling plate 35, the heat of vaporization of the liquefied gas is easily transmitted, and the cooling effect can be enhanced. As the metal cooling plate 35, a metal material having high thermal conductivity such as aluminum, copper, titanium, or an alloy thereof is preferably used. The thickness of the cooling plate 35 is not particularly limited, but is preferably 0.01 to 2 mm in order to maintain the cooling effect and improve heat transfer from the periphery of the communication path 34.

  Further, in the present embodiment, as shown in FIG. 1A, the cooling plate 35 is formed in a convex shape that is convex toward the side opposite to the base portion 36, and the top of the convex cooling plate 35 is Further, it is formed so as to protrude from the end portion on the outlet side of the communication passage 34 (the upper end portion in FIG. 1A). That is, as shown in FIG. 1A, the cooling plate 3 is curved so that the central portion of the cooling plate 35 protrudes from the outer peripheral side of the cooling plate 35 provided with the communication path 34, and the cooling tool 3 is pressed against the human body. Sometimes, only the central portion of the cooling plate 35 is in contact with the human body, and the outer peripheral portion of the cooling plate 35 is configured not to contact. Accordingly, since the content A discharged from the aerosol container 2 collides with the partition wall 36a through the central passage 31a and flows toward the communication passage 34, the liquefied gas in the content A is less likely to concentrate on the skin and come into contact with the skin. Can prevent the skin from being overcooled.

  The base portion 36 is a member that is attached to the main body portion 31 and supports the cooling plate 35. In addition, the base portion 36 is non-metallic between the internal space 33 and the cooling plate 35 so that the cooling plate 35 is not directly cooled by the liquefied gas in the contents A moved from the central passage 31a into the internal space 33. A partition wall 36a made of metal is provided. In the present embodiment, the entire base portion 36 is made of a non-metal, but only the partition wall 36a may be made of a non-metal. By providing the partition wall 36a between the internal space 33 and the cooling plate 35, the central portion of the cooling plate 35 that is a contact portion with the human body is not cooled too much, thereby preventing pain due to overcooling of the skin. be able to. The non-metallic material used for the partition wall 36a and the base portion 36 is not particularly limited as long as it is a material having a low thermal conductivity other than metal. However, synthetic resins such as polyacetal, nylon, and polybutylene terephthalate, silicone rubber, synthetic rubber, etc. Rubber is preferably used. The thickness of the partition wall 36a is not particularly limited, but heat from the cooling plate 35 is difficult to be transferred into the internal space 33, but 0.5 to 5 mm in order to appropriately cool the central portion of the cooling plate 35. It is preferable that

  In the present embodiment, the communication passage 34 is formed as a passage formed through the partition wall 36 a and the cooling plate 35. More specifically, a partition-side communication path 34a formed in the partition wall 36a and a cooling-plate-side communication path 34b formed in the cooling plate 35 serve as one path between the internal space 33 and the outside of the cooling tool 3. Communicate. By being configured as a passage that penetrates the partition wall 36a and the cooling plate 35, when the content A contains an active ingredient, the discharged material discharged by the cooling plate 35 can be easily applied to the skin. In addition, as shown in FIG. 1B, in the present embodiment, the communication path 34 is formed as a plurality of communication holes provided in an annular shape. As in the present embodiment, by providing the communication passages 34 in an annular manner at equal intervals, the cooling plate 35 can be evenly cooled from the outer peripheral side of the cooling plate 35 toward the central portion.

  2A to 2C show a modification of the communication path 34 of the present embodiment. In FIG. 2 (a), the partition side communication passage 34a and the cooling plate side communication passage 34b are arranged concentrically, but are arranged at predetermined intervals on the circumference of the concentric circles. The passage 34a and the cooling plate side communication passage 34b are connected to each other by a groove-like passage 34c provided in the partition wall 36a. FIG. 2B shows that the partition wall side communication path 34a and the cooling plate side communication path 34b are arranged at predetermined intervals on the circumferences of different diameters. 34b are connected to each other by a groove-like passage 34c provided in the partition wall 36a. 2 (a) and 2 (b), the contact between the liquefied gas in the contents A and the cooling plate 35 is equal to the length of the groove-like passage 34c at the outer peripheral portion of the cooling plate 35. Since the area increases, the cooling effect on the outer peripheral portion of the cooling plate 35 is enhanced, and the cooling plate 35 can be cooled more efficiently. In the modification of FIG. 2C, the communication path 34 is formed in a long hole or slit shape. In this case, since the opening area of the communication path 34 is large, the cooling rate of the cooling plate 35 can be increased.

  Next, the effect of the aerosol product 1 of the present invention will be described with reference to FIG.

  As shown in FIG. 3, the aerosol product 1 of the present embodiment is used by pressing the cooling plate 35 against the skin S of the human body. As shown in FIG. 3, the central portion including the top of the cooling plate 35 contacts the skin S. From this state, when the entire aerosol product 1 is pressed against the skin S, the stem 21d is pushed into the housing 21b against the urging force of the spring 21c, and the stem hole closed by the stem rubber 21e becomes aerosol. It communicates with the inside of the container 2. Thereby, the content A inside the aerosol container 2 moves to the internal space 33 from the stem 21d through the central passage 31a. The liquefied gas in the content A begins to vaporize in the content A that has moved to the internal space 33 whose sectional area is larger than that of the central passage 31a. In addition, the content A that has moved to the internal space 33 collides with the partition wall 36a and moves to the left and right in FIG. 3 to cool the entire content of the internal space 33 while cooling the content A itself. Opposite, it is discharged from the communication passage 34 to the outside. The content A self-cooled in the internal space 33 contains a part of the liquefied gas, and the liquefied gas is vaporized when it is discharged to the outside from the communication path 34 to cool the cooling plate 35. it can.

  Since the cooling plate 35 is provided with a non-metallic partition wall 36a, the central portion that is in contact with the skin S is directly cooled by the liquefied gas in the content A that has moved from the central passage 31a to the internal space 33 and is vaporized. Instead, it is cooled from the outer peripheral portion side of the cooling plate 35 toward the central portion by the discharge containing a part of the liquefied gas discharged from the communication passage 34. Since the cooling plate 35 is made of a metal having high thermal conductivity, heat is easily transmitted from the outer peripheral portion of the cooled cooling plate 35 to the central portion of the cooling plate 35 that contacts the skin S. Therefore, the cooling plate 35 can be strongly cooled by using the metal cooling plate 35. In addition, since the cooling plate 35 has high thermal conductivity, heat is transmitted from the skin S toward the center of the cooling plate 35 due to the body temperature of the human body, but between the cooling plate 35 and the internal space 33, the thermal conductivity is transmitted. A low non-metallic partition wall 36a is provided. The partition wall 36a makes it difficult for heat from the skin S to be transmitted into the internal space 33 cooled by vaporization of the liquefied gas. Therefore, the temperature in the internal space 33 cooled by the liquefied gas moved from the aerosol container 2 into the internal space 33 is unlikely to rise, and the liquefied gas in the contents A is slowly vaporized to maintain the cooling effect. it can.

  Further, since the cooled content A including a part of the liquefied gas is discharged from the end portion on the outlet side of the communication path 34 provided on the outer peripheral portion of the cooling plate 35, the end of the communication path 34 on the outlet side The cooling plate 35 is cooled from the portion toward the top of the cooling plate 35. Therefore, since cooling is performed from the outer peripheral side of the cooling plate 35 toward the center, the central portion of the cooling plate 35 that directly contacts the human skin S is not easily overcooled, and pain due to overcooling of the skin can be prevented. . Moreover, since the top part of the cooling plate 35 is located at a position protruding from the end portion on the outlet side of the communication path 34, the end of the communication path 34 on the outlet side when the cooling plate 35 is pressed against the skin S of the human body. The part is not blocked by the skin S of the human body. Accordingly, pain due to overcooling of the skin S can be prevented, and the contents A can be continuously discharged from the aerosol container 2 while the cooling plate 35 is pressed against the skin S of the human body.

  The cooling plate 35 of the present embodiment is shown as a convex cooling plate 35 curved in a dome shape from the outer periphery to the center of the cooling plate 35, but the convex cooling plate has the shape shown in the figure. For example, it may be formed in a step shape in which a step is provided between the central portion and the outer peripheral portion, or only the central portion may be formed in a dome shape, and the outer peripheral portion may be formed as a flat surface.

  Further, the communication path 34 of the present embodiment is shown as having eight circular communication holes formed, but the shape, number and arrangement relationship of the communication paths 34 are not limited to those shown in the figure. As long as the object of the present invention can be achieved, it may be a continuous annular communication path, or may be provided in an irregular arrangement relationship.

  Moreover, although the main-body part 31 and the cooling part 32 of this embodiment are shown as a separate member, you may use the cooling tool which integrated the main-body part and the cooling part. Further, in the present embodiment, the partition wall 36a is shown as a part of the base portion 36, but the partition wall 36a may be provided by being attached as a separate member.

  Moreover, although the aerosol product 1 of this embodiment is shown as a push-down type in which the stem hole is opened by moving below the axis of the aerosol container 2, the stem hole is opened by tilting the stem. Other discharge structures such as such a configuration may be used. Moreover, although the aerosol product 1 of the present embodiment has been described by taking the aerosol product 1 in an inverted state as an example, it may be configured to be used in an upright state by providing a dip tube or the like. .
