Description

  The present invention relates to an aerosol product for human body. More specifically, an aerosol composition containing a stock solution, a liquefied gas, and a compressed gas; an aerosol container having an aerosol valve fixed to a pressure-resistant container and filled with the aerosol composition; and an injection member attached to the aerosol valve; It relates to an aerosol product for human body having

  Conventionally, aerosol products are filled with an aerosol composition consisting of a stock solution and a propellant into an aerosol container in which an aerosol valve (hereinafter referred to as “valve”) is fixed to the opening of a bottomed cylindrical pressure-resistant container. The aerosol composition is released into the atmosphere by operating the injection member attached to the air, and is discharged in the form of mist, foam, etc. using the vapor pressure of the propellant or the state change that changes from liquid to gas It is widely used in human products such as cosmetics and pharmaceuticals, household products such as insecticides and deodorants, and industrial products.

  Currently, liquefied gas such as liquefied petroleum gas and dimethyl ether, and compressed gas such as nitrogen gas and carbon dioxide are used as propellants. The liquefied gas is a liquid having a vapor pressure in the aerosol container, but when released into the atmosphere, the liquefied gas is instantly vaporized and its volume expands. Using such characteristics of the propellant, it is possible to obtain excellent performance such as obtaining a fine mist, spreading the mist over a wide range and applying uniformly, and obtaining an excellent cooling feeling due to heat of vaporization. .

  In addition, a vapor tap hole, which is a communication hole that communicates the inside of the housing and the gas phase portion in the aerosol container, is provided on the side surface of the valve housing, and flows into the valve during injection. A liquefied gas is mixed into the liquid aerosol composition. As a result, it is possible to obtain such effects that the specific gravity of the projectile is reduced, the amount of injection is suppressed and the liquid does not easily drip, and the momentum of injection is weakened and soft injection is possible.

  In Patent Document 1, a throttle member provided with a throttle passage having the same diameter as a radial discharge passage (stem hole) having a diameter of 0.2 to 0.3 mm is inserted into a stem, and the gap between the throttle passage and the injection hole is inserted. An aerosol container for vaporizing liquefied gas in a space is disclosed. By vaporizing the liquefied gas in the space, the specific gravity of the projectile is reduced, and the injection amount is suppressed, thereby preventing dripping.

  Moreover, the aerosol valve | bulb provided with the means which vaporizes liquefied gas in the internal channel | path in an aerosol container and injects a liquid aerosol composition with the vaporized gas is disclosed (patent documents 2-4). In Patent Document 2, a small chamber for vaporizing the liquefied gas is provided in the dip tube, and in Patent Document 3, the small chamber is provided between the housing and the dip tube. In Patent Document 4, two insert tips for reducing the cross-sectional area of the passage in the tube are inserted into the dip tube, and the liquefied gas is vaporized by a space between the insert tips.

  Patent Documents 5 and 6 disclose an aerosol container provided with a sintered resin (sintered body) having open cells at one place of an injection passage. Patent Document 5 aims to make the sprayed mist particles finer, while Patent Document 6 aims to suppress the flow rate, soften the spray pattern, and prevent clogging. No mention is made of the relationship between composition and aerosol container.

  However, in recent years, since liquefied gas is a volatile organic solvent, the burden on the environment is regarded as a problem, and the development of aerosol products with a reduced amount of liquefied gas is being promoted. On the other hand, if the amount of the liquefied gas is reduced, there is a problem that the above-described excellent effect is hardly obtained and the performance is lowered. In particular, when the blending amount of the liquefied gas is 40% by weight or less in the aerosol composition, it becomes difficult to use a valve having a vapor tap hole that communicates the gas phase portion in the aerosol container and the inside of the valve housing. There was a problem. That is, a valve with a vapor tap hole injects not only the liquefied gas dissolved in the stock solution but also the liquefied gas in the aerosol container, so that the consumption of the liquefied gas is large and the liquefied gas content is high. In the case of a small amount of aerosol composition, the injection state is likely to change, and only the stock solution remains and cannot be injected to the end. On the other hand, when a valve not provided with a vapor tap hole is used, only the liquid portion of the aerosol composition is injected, so the injection amount per unit time (g / second, hereinafter referred to as injection amount) increases and dripping on the injection surface. In addition, since the momentum of injection is strong, the rebound on the injection surface increases, resulting in problems such as poor adhesion.

  As a means for preventing liquid dripping, a method of suppressing the injection amount by reducing the stem hole of the valve or the injection hole of the injection member is conceivable. However, when impurities such as dust are mixed in the manufacturing process, clogging easily occurs. Further, since the processing becomes fine, there is a problem that it is difficult to supply with stable performance.

  In addition, in the technique of Patent Document 1, it is necessary to make the throttle passage small (about 0.2 to 0.25 mm) in order to obtain the above effect sufficiently, and the throttle member is an external passage from the stem hole to the injection hole. Therefore, even if the user finishes the spraying operation and the stem hole is closed, the aerosol composition tends to remain between the stem hole and the throttle member, and an after-draw is likely to occur. On the other hand, if the passage of the throttle member is enlarged to prevent after-draw, the liquefied gas is less likely to vaporize in the space, and the effect of suppressing the injection amount is difficult to obtain.

  Further, in the techniques of Patent Documents 2 to 4, these methods can prevent after-draw because the liquefied gas is vaporized in the internal passage. However, if the amount of the liquefied gas is small, the small chamber is cut off. If the area (space) is large, a breathing phenomenon that stays in the small chamber and is not continuously injected tends to occur, and the injection amount is likely to change. On the other hand, if the cross-sectional area of the small chamber is small, the liquefied gas is difficult to vaporize and the effect of suppressing the injection amount cannot be obtained.

  The present invention has been made in view of the above-mentioned conventional problems, and even when the amount of liquefied gas in the aerosol composition to be filled in the aerosol product is reduced, a soft injection state can be obtained and adhesion to the injection surface can be achieved. An object of the present invention is to provide an aerosol product that is high, can suppress fluctuations in the injection amount during injection, can prevent liquid dripping on the injection surface, and can prevent an after-draw phenomenon.

Embodiment 1
As shown in FIG. 1 (a) and FIG. 1 (b), an aerosol product 100 for a human body according to the present embodiment includes an aerosol container 2, an injection member 3 attached to an aerosol valve 22 of the aerosol container 2, and an aerosol. It is comprised from the aerosol composition 6 with which the inside of the container 2 is filled.

  The aerosol container 2 includes a bottomed cylindrical container body 21 having pressure resistance, and an aerosol valve 22 fixed to the opening of the container body 21.

  The container body 21 is made of a metal plate such as aluminum or tinplate or a disk-shaped object having a bottomed cylindrical shape by impact processing or drawing and ironing processing, and further, a shoulder portion and a bead portion are formed by necking processing and curling processing. Yes. In addition, a three-piece can, or a two-piece can, in which a metal plate such as a tin plate or a tin-nickel steel plate is cylindrically attached to a bottom portion and a metal base having a bead portion fixed by double winding. It may be used. Furthermore, other materials having pressure resistance such as pressure resistant glass and synthetic resin may be used.

  The aerosol valve 22 includes a mounting cup 220 that is fixed to the bead portion of the container body 21 via a gasket, a housing 223 that is held at the center of the mounting cup 220, and a spring 225 that is housed in the housing 223 together with the spring 225. Stem 221 always biased upward, and stem 221 is inserted into the inner diameter surface thereof, and stem 221 covers stem hole 221a of stem 221 with stem 221 biased upward by the repulsive force of spring 225 or stem hole A stem rubber 222 that covers the entire outer peripheral surface below 221 a and seals the inside of the aerosol container 2, and a tube 226 attached to the tube attachment portion 224 of the housing 223.

  Although it does not specifically limit as the mounting cup 220, A general thing can be used normally as what is used for an aerosol container. For example, aluminum, tin, stainless steel, or the like can be used according to the material of the container body 21.

  The housing 223 has a bottomed cylindrical shape, and a bottom hole 223a that communicates the inside of the housing 223 and the tube 226 is provided at the bottom. Further, as the housing 223 used in the present invention, a gas phase communication hole (vapor tap hole) for communicating the inside of the housing 223 and the gas phase portion G of the aerosol container 2 is not formed in the cylindrical body portion. In addition, a cylindrical tube mounting portion 224 is provided below the bottom of the housing 223, the upper end of the tube 226 is mounted on the outer periphery of the tube mounting portion 224, and a porous member is provided inside the tube mounting portion 224. 4 is inserted. In addition, the lower end (free end) of the tube 226 is opened near the inner bottom surface of the container main body 21, and becomes an introduction hole 226a for introducing the aerosol composition when the valve is opened.

  The stem 221 has a cylindrical portion at the top, and a stem hole 221a is formed on the side surface thereof. The inside of the cylindrical portion is a stem passage 221b communicating with the stem hole. The stem passage 221b is a columnar shape for reducing the volume of the stem passage 221b, and a notch-like groove extending in the axial direction on the side surface thereof. A bush 5 in which 5a is formed is inserted. FIG. 2 shows an example of a groove 5a formed in the bush 5, and FIG. 2 (a) shows a groove formed linearly in the longitudinal direction of the bush 5. FIG. Is a spiral groove formed on the side surface of the bush 5. By inserting the bush 5 into the in-stem passage 221b, the volume of the in-stem passage becomes small and the amount of aerosol composition remaining in the in-stem passage is reduced when the stem hole is closed, thereby preventing after-drawing. Further, since the flow rate (flow velocity) of the aerosol composition passing through the passage in the stem is suppressed, the liquid aerosol composition L filled in the housing 223 when not in use (when the stem hole is closed) becomes the stem hole 221a. There is an effect of preventing the injection amount from being increased due to the injection of only the liquid aerosol composition without being mixed with the gas vaporized by passing through the porous member 4 immediately after the opening. In particular, when the injection amount is reduced using the porous member 4 having a small pore diameter, the difference between the injection amount immediately after the start of injection and the injection amount after a while (for example, after 1 to 2 seconds) becomes large, and the injection amount becomes large. Although it tends to fluctuate, the fluctuation of the injection amount can be reduced by inserting the bush 5.

The gap between the stem inner passage 221b and the bush 5 or the gap formed by the notch-shaped groove 5a extending in the axial direction provided on the side surface of the stem inner passage 221b and the bush 5 becomes the passage of the aerosol composition. Passage cross-sectional area 0.05 to 0.5 mm ² of (grooves 5a), preferably further is 0.07~0.3mm ^2. When the cross-sectional area of the passage is smaller than 0.05 mm ² , dust or dust is likely to be clogged, and when larger than 0.5 mm ² , the liquid aerosol composition L in the housing is easily injected immediately after opening the valve, The injection amount tends to fluctuate. Here, the cross-sectional area of the passage (groove 5a) refers to the area when cut perpendicular to the longitudinal direction of the groove.

  As the bush 5, a material molded using a synthetic resin such as polyacetal, polyamide, polyester, or polyolefin can be used.

Further, the cross-sectional area of the stem hole 221a is, 0.05 to 0.3 mm ^2, preferably further is 0.07~0.2mm ^2. When the cross-sectional area of the stem hole 221a is smaller than 0.05 mm ² , the stem hole 221a is likely to be clogged with dust or dust mixed in the manufacturing process, and the processing becomes fine, so the accuracy is poor and the performance is not stable. On the other hand, when the cross-sectional area of the stem hole 221a is larger than 0.3 mm ² , the injection amount becomes large and the liquid is liable to drip and the usability is likely to be lowered.

  The stem rubber 222 is not particularly limited, but a general one that is generally used for the aerosol valve 22 can be used. For example, synthetic rubber such as acrylonitrile butadiene rubber (NBR), fluorine rubber, butyl rubber (IIR), styrene butadiene rubber (SBR), isobutylene rubber, isoprene rubber (IR), chloroprene rubber (CR), silicone rubber, and olefin elastomer In addition, those molded into a plate-like ring shape using a thermoplastic elastomer such as a polyester-based elastomer, a polyamide-based elastomer, and a silicone-based elastomer can be used.

  The tube 226 is a hollow body, and at one end thereof, the tube mounting portion 224 of the housing 223 is fitted into the hollow body, and the other end (introduction hole 226a) is attached to face the bottom of the container body. . The material of the tube 226 is not particularly limited, but it is preferable to use a synthetic resin such as polyethylene, polypropylene, or nylon. Moreover, in this Embodiment, the porous member 4 (sintered body) is attached in the tube attachment part 224 with which the tube 226 was attached outside.

  The porous member 4 is formed, for example, at a temperature equal to or lower than the melting point or partially melted after pressurizing and shaping a resin such as polyethylene, polypropylene, ethylene vinyl acetate, methyl methacrylate, polytetrafluoroethylene, and polysulfone in a mold. A synthetic resin sintered body having a network structure formed by heating can be used.

  The pore diameter of the porous member 4 is preferably 0.5 to 50 μm, more preferably 1 to 30 μm. When the pore diameter is smaller than 0.5 μm, the speed at which the liquid aerosol composition L passes is slow, it takes time for the liquefied gas to start to vaporize, and the injection amount immediately after opening the stem hole 221a tends to increase. On the other hand, when the pore diameter is larger than 50 μm, the liquefied gas is hardly vaporized even when the liquid aerosol composition L passes, and the injection amount is hardly suppressed.

Moreover, it is preferable that the cross-sectional area of the porous member 4 is 0.2-80 mm < ² >, Furthermore, 0.5-50 mm < ² >. When the cross-sectional area is smaller than 0.2 mm ^{2, the} liquefied gas is difficult to vaporize and the injection amount is difficult to be suppressed. On the other hand, when the cross-sectional area is larger than 80 mm ² , the vaporization of the liquefied gas is too much and the liquid aerosol composition is difficult to move to the injection hole side, and the liquid aerosol composition and the gas obtained by vaporizing the liquefied gas are generated. The breathing phenomenon that is repeatedly injected tends to occur. Here, the cross-sectional area of the porous member 4 refers to the area of the cut surface when cut perpendicular to the longitudinal direction of the tube 226.

The injection member 3 includes a stem mounting portion 31 that is mounted on the stem 221 of the valve, an injection hole 3a that sprays the aerosol composition to the outside, and an intra-button passage 3b that communicates the stem mounting portion 31 and the injection hole 3a. . The injection hole 3a is provided at the center of the bottom of the nozzle mounted on the main body of the injection member 3, and a mechanical breakup mechanism 32 for increasing the spray pattern is provided on the back surface of the nozzle. Sectional area of the injection hole 3a is 0.05 to 0.3 mm ^2, preferably further is 0.07~0.2mm ^2. If the cross-sectional area of the injection hole 3a is less than 0.05 mm ² , the aerosol composition tends to stay in the button passage 3b immediately after the stem hole 221a is closed, and an after-draw is likely to occur. On the other hand, if it exceeds 0.3 mm ² , it is difficult to obtain the effect of the mechanical breakup mechanism 32 and the spray pattern is difficult to spread.

  In the present invention, the passage from the introduction hole 226a at the bottom side of the container body 21 of the tube 226 into which the liquid aerosol composition L is introduced to the injection hole 3a of the injection member 3 through which the aerosol composition is injected to the outside. Is referred to as an injection passage, and among the injection passages, a passage from the introduction hole 226a to the stem hole 221a is referred to as an internal passage, and a passage from the stem hole 221a to the injection hole 3a is referred to as an external passage. A porous member 4 is provided in the part, and a bush 5 is provided in a part of the external passage.

  The aerosol composition filled in the aerosol container 2 contains a stock solution, a liquefied gas, and a compressed gas.

  The undiluted solution is atomized during spraying to form a mist, and gives the active ingredient to a part of the human body such as skin and hair. The stock solution is not particularly limited, but it is preferable to use a mixture of an active ingredient in an aqueous solvent containing water from the viewpoints of safety against fire and load on the environment.

  As the water, for example, purified water, ion-exchanged water, deep sea water, physiological saline, and the like can be used, and the blending amount thereof is preferably 20 to 80% by weight, more preferably 30 to 70% by weight in the stock solution. When the blending amount of water is less than 20% by weight, the sprayed mist (hereinafter referred to as spray particles) is easily ignited and the safety against fire is lowered. In particular, the aerosol product according to the present invention has a feature that a soft injection state is obtained with a low injection momentum. However, when the spray particles are ignited, a flashback phenomenon in which a flame flows back to the injection hole easily occurs. On the other hand, when the amount of water exceeds 80% by weight, the drying property is deteriorated, the liquid is liable to drip on the ejection surface, and the feeling of use tends to be lowered.

  A part of the solvent is used for the purpose of improving the dryness and improving the feeling of use, adding an active ingredient that does not dissolve in water, making the spray particles finer, and reducing the increase in pressure caused by the temperature rise. It is preferable to blend a monovalent aliphatic alcohol having 2 to 5 carbon atoms. Examples of the aliphatic alcohol include ethanol and isopropanol. The blending amount of the aliphatic alcohol is preferably 10 to 70% by weight, more preferably 20 to 60% by weight in the stock solution. When the blending amount of the aliphatic alcohol is less than 10% by weight, it is difficult to obtain the above effect, and when it exceeds 70% by weight, the spray particles are easily ignited and the safety against fire is likely to be lowered.

  The active ingredient can be appropriately selected according to the use and purpose of the aerosol product. For example, tea extract, lauric acid methacrylate, methyl benzoate, methyl phenylacetate, geranyl crotolate, acetophenone myristate, benzyl acetate, propionic acid Deodorant components such as benzyl; bactericidal components such as paraoxybenzoate, sodium benzoate, potassium sorbate, phenoxyethanol, benzalkonium chloride, benzethonium chloride, chlorhexidine chloride, photosensitizer, parachlormetacresol; 1-menthol, camphor, etc. Anti-perspirant components such as chlorohydroxyaluminum; Astringent components such as allantoin hydroxyaluminum, citric acid, lactic acid, and tannic acid; Anti-flame such as allantoin, glycyrrhetinic acid, and azulene Ingredients: Local anesthetic ingredients such as dibucaine hydrochloride, tetracaine hydrochloride, lidocaine hydrochloride; antihistamine ingredients such as diphenhydramine hydrochloride, chlorfemiramin maleate; anti-inflammatory analgesic ingredients such as methyl salicylate, ketoprofen, indomethacin, felbinac, piroxicam, crotamiton; N , N-diethyl-m-toluamide (diet), caprylic acid diethylamide and other pest repellent components; paraaminobenzoic acid ester, octyl salicylate, phenyl salicylate, isopropyl paramethoxycinnamate, octyl paramethoxycinnamate, paramethoxycinnamon UV-absorbing components such as 2-ethylhexyl acid, 2,4-dihydroxybenzophenone, 2-hydroxy-4-methoxybenzophenone; glycine, alanine, leucine, isoleucine Amino acids such as serine, threonine tryptophan, cystine, cysteine, aspartic acid, glutamic acid; retinol, retinol palmitate, pyridoxine chloride, benzyl nicotinate, nicotinamide, dl-α-tocopherol nicotinate, vitamin D2 (ergocassipherol), Vitamins such as dl-α-tocopherol, dl-α-tocopherol acetate, pantothenic acid, biotin; antioxidant components such as α-tocopherol, dibutylhydroxytoluene, butylhydroxyanisole; Dokudami extract, Oat extract, Peonies extract, Loofah extract , Kina extract, Primrose extract, Rose extract, Lemon extract, Aloe extract, Ginger root extract, Eucalyptus extract, Sage extract, Tea extract, Seaweed extract, Placen Extract, extract of silk extract, synthetic fragrances, such as perfumes, such as natural flavors and the like.

  The compounding amount of the active ingredient is preferably 0.1 to 20% by weight, more preferably 0.5 to 10% by weight in the stock solution. When the blending amount of the active ingredient is less than 0.1% by weight, the active ingredient concentration in the sprayed product is low, and it is necessary to inject a large amount in order to obtain a desired effect. On the other hand, if it exceeds 20% by weight, the concentration of the active ingredient in the injection becomes high, and it becomes easy to inject beyond the upper limit of use.

  In addition, the stock solution contains oily ingredients, polyhydric alcohols, surfactants, etc. for the purpose of improving the feeling of use, such as giving luster, improving touch, improving sliding and combing, and improving moisture retention. An auxiliary component can be mix | blended.

  Examples of the oil component include higher alcohols such as lauryl alcohol, cetyl alcohol, stearyl alcohol, myristyl alcohol, oleyl alcohol, and isostearyl alcohol; higher hydrocarbons such as squalane, squalene, liquid paraffin, and isoparaffin; lauric acid, myristic acid, Higher fatty acids such as palmitic acid, stearic acid, oleic acid; silicone oils such as methylpolysiloxane, decamethyltetrasiloxane, octamethylcyclotetrasiloxane, methylphenylpolysiloxane; isopropyl myristate, cetyl octanoate, octyldodecyl myristate, Ester oils such as isopropyl palmitate, diethyl phthalate, diethoxyethyl phthalate, diethoxyethyl succinate; beeswax, Norin, candelilla wax, wax (waxes), such as paraffin wax; and the like; camellia oil, corn oil, olive oil, castor oil, safflower oil, jojoba oil, fats and oils, such as palm oil.

  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 Coalescing, poly (oxyethylene-oxypropylene) methylpolysiloxane copolymer, and the like.

  Examples of the polyhydric alcohol include propylene glycol, 1,3-butylene glycol, glycerin and the like.

  When the auxiliary component is blended, the blending amount is preferably 0.1 to 20% by weight, more preferably 0.5 to 10% by weight in the stock solution. When the amount of the auxiliary component is less than 0.1% by weight, it is difficult to obtain the effect of adding the auxiliary component, and when it exceeds 20% by weight, the sticky feeling becomes stronger and the drying property becomes worse. It tends to decline. Moreover, it becomes difficult to obtain a uniform aerosol composition.

  The liquefied gas acts as a propellant that sprays the stock solution in the form of a mist. The liquefied gas is a liquid in the aerosol container, but at least a part thereof is vaporized when the stem hole is opened and the atmosphere and the aerosol container communicate with each other and pass through the porous member.

  Examples of the liquefied gas include propane, normal butane, isobutane, and liquefied petroleum gas, dimethyl ether, and a mixture of liquefied petroleum gas and dimethyl ether, which are mixtures thereof. In addition, you may mix | blend low boiling-point solvents, such as normal pentane and isopentane, with liquefied gas. Of the liquefied gas, it is preferable to use dimethyl ether because a uniform aerosol composition is easily obtained.

  The blending amount of the liquefied gas is preferably 10 to 40% by weight, more preferably 20 to 35% by weight in the aerosol composition. When the blending amount of the liquefied gas is less than 10% by weight, the amount of vaporization when passing through the porous member is small, and the effect of the present invention is hardly obtained. Furthermore, the aerosol composition that has passed through the porous member tends to stay in the injection passage, and a breathing phenomenon is likely to occur. On the other hand, if it exceeds 40% by weight, the momentum of injection becomes strong and the feeling of use tends to decrease.

  Although the compressed gas is partly dissolved in the liquid aerosol composition L, most of the compressed gas is in the gas phase portion in the aerosol container and acts as a pressurizing agent for pressurizing the liquid aerosol composition L, and the stem hole 221a. There is an effect that the aerosol composition L is stably supplied to the porous member 4 when the is opened, and the breathing phenomenon is not caused.

  Examples of the compressed gas include nitrogen gas, carbon dioxide gas, nitrous oxide gas, and compressed air. Moreover, it is preferable to fill the compressed air so that the pressure inside the aerosol container 2 is 0.4 to 0.7 MPa, more preferably 0.45 to 0.65 MPa at 25 ° C. When the pressure inside the aerosol container 2 is less than 0.4 MPa, a breathing phenomenon is likely to occur at a low temperature, and when it exceeds 0.7 MPa, the pressure becomes too high at a high temperature, which is not preferable from the viewpoint of safety.

  Below, the injection operation | movement of the aerosol product 100 of this Embodiment is demonstrated.

  As shown in FIG. 1B, the aerosol product 100 of the present invention configured as described above has a stem 221 by a user performing an injection operation such as pushing down the top surface of the injection member 3 with a finger or the like. Is pushed down to open the stem hole 221a, and the inside of the aerosol container 2 communicates with the atmosphere. At this time, the liquid aerosol composition L in the tube 226 passes through the porous member 4 and at least a part of the liquefied gas is vaporized, and in the housing 223, an aerosol composition in which liquid and gas are mixed is obtained. It flows into the stem internal passage 221b through the hole 221a, and is further injected from the injection hole 3a through the button internal passage 3b. When the liquefied gas is vaporized in the injection passage up to the injection hole 3a, the density of the injection is reduced and the injection amount is suppressed. Furthermore, when the aerosol composition passes through the porous member 4, the flow velocity is suppressed, and the momentum of injection is weakened, resulting in a soft injection state.

  The injection amount when the pressure inside the aerosol container 2 is 0.6 MPa is preferably 0.01 to 0.7 g / second, more preferably 0.05 to 0.5 g / second. When the injection amount is less than 0.01 g / second, the difference between the injection amount immediately after releasing the stem hole 221a and the injection amount after a while (for example, after 1 to 2 seconds) becomes large, and the injection state easily changes. When it exceeds 0.7 g / second, the feeling of use is likely to be lowered, such as liquid dripping on the ejection surface, and the momentum of ejection is increased.

  Moreover, it is preferable that the injection distance which the spray particle reaches when the pressure inside the aerosol container 2 is 0.6 MPa is 10 to 80 cm, and more preferably 15 to 70 cm. When the spray distance is shorter than 10 cm, the spray particles are easily affected by the surrounding conditions to be used, and the amount of adhesion tends to decrease. When the distance is longer than 80 cm, the momentum of injection is strong and the amount of adhesion tends to decrease. The aerosol product of the present invention is in a soft spray state despite the high pressure inside the aerosol container of 0.4 to 0.8 MPa, and is difficult to dripping and has a high adhesion amount.
