Description

  The present invention relates to a packaged product in which an inner container for storing a plurality of contents (stock solutions) is stored in one outer container.

JP 2003-205983 A Japanese Patent No. 3079150 JP-A-8-169482 JP 2003-40368 A Conventionally, as a product that discharges multiple contents at the same time, different contents are filled into two aerosol containers, bundled together, and a discharge member such as a common nozzle is attached to the stem of each valve. There is known a two-component mixing type aerosol product that is not mixed before and is mixed for the first time at the time of discharge (Patent Document 1). This can be discharged, for example, by filling a two-component reactive hair dye composed of a first agent blended with an oxidative dye and a second agent blended with an oxidizer and mixing them. However, since this container bundles two containers, the structure of the discharge member becomes complicated, and the operation for opening the two valves simultaneously and evenly is difficult. Moreover, since it becomes longer in the connected direction, it is difficult to grasp when the container is grasped by hand. In addition, this requires two containers, and the contents must be filled separately, which not only increases costs, but also varies in the amount of propellant filling in each container. Product pressure may vary. For this reason, it is difficult to adjust the discharge amount of the contents.

  On the other hand, Patent Document 2 discloses a discharge product (packaging preparation) in which a plurality of contents are filled in one container. This discharge product contains a foldable inner bag inside an outer container, and the inner bag is filled with different types of contents, particularly gel-like contents in layers. In this case, when the gel-like contents are discharged from one nozzle or spout, the respective contents can be continuously discharged in a multilayer state (layered discharge). And since it is comprised with one aerosol product, a structure is simple and it is easy to hold a container with a hand. Furthermore, since the contents are injected with the propellant filled in one container, the pressure to be injected is the same, and the discharge amounts of both are easy to adjust.

  In addition, in FIG. 3 of patent document 2, in order to ensure that the inner bag is crushed inward from three directions (or four or more directions), a longitudinal fold, a crease or a rib may be provided in advance. It is disclosed. A similar inner bag is also disclosed in FIGS.

In the discharge product of Patent Document 2, when filling an inner bag with a plurality of contents, the lower contents are filled and then the upper contents are filled as they are, so that the contents are slowly filled so as not to mix. There is a need. Therefore, there is a problem that the filling speed cannot be increased (the contents can be filled vigorously), and the filling efficiency is low. Depending on the contents, the contents may be mixed during storage or transportation. In that case, the active ingredient in the contents reacts inside the inner bag, and the effect of the active ingredient cannot be obtained when discharged. In addition, the inner bag provided with a number of folds in the vertical direction is folded evenly as the contents are discharged, so there is an advantage that the remaining amount after discharging the whole amount is small, but mixing is prevented. I can't.
In particular, when a highly reactive content such as the two-component reactive hair dye of Patent Document 1 is filled, the alkaline first agent is stored in the inner bag (unused state). It was found that the active ingredient (reactive ingredient) started to react at the contact surface with the acidic second agent, and the desired effect could not be obtained during use.

Patent Document 4 discloses a discharge device for a plurality of contents provided with a plurality of cylinders in an outer container. When two cylinders and a piston are used in this way, the contents can be stored separately, so that the contents do not mix during storage or transportation, but the number of parts increases. In addition, when using a single cylinder, it is difficult to fill the contents.
Moreover, when the two-component reactive hair dye of Patent Document 1 is filled in the discharge device of Patent Document 4, the first agent and the second agent are stored in a separated state, but stored for a long period of time. It was found that the first agent and the second agent initiate the reaction.

  Furthermore, the present inventor provides a packaged product that can be stably stored without being reacted with the reaction components, even if the content is highly reactive, such as a two-component reactive hair dye. As a result of repeated studies to obtain a barrier function that not only blocks the contact between the alkaline first agent and the acidic second agent, but can also block gases such as ammonia and oxygen that are generated over time from the contents. It has been found that a packaging container having

  It is an object of the present invention to provide a packaged product containing an inner bag that can stably store a plurality of highly reactive contents in one outer container.

The packaged product of the present invention (Claim 1) includes an outer container, an inner bag that is accommodated in the outer container, has a plurality of storage portions, and at least a part of each storage portion has flexibility, and an inner bag A plurality of stock solutions that are sealed and stored in each storage section and means for pressurizing the inner bag, the inner bag is partitioned into a plurality of storage sections by partition elements, and the inner bag is partitioned vertically. being, the inner bag, filled with an aqueous ammonia solution has a pH of 11 to 13 in one housing part, of the water when the lapse of one month at 25 ° C. in a state filled with water to the remaining housing portion It is characterized by having a barrier function with a pH change of less than 3.

The stock solution of such a packaged product is preferably composed of an alkaline stock solution and an acidic stock solution ( Claim 2 ). Furthermore, the thing whose pH difference of the said alkaline undiluted | stock solution and acidic undiluted | stock solution at 25 degreeC is 5-10 is preferable ( Claim 3 ).
In addition, the acidic stock solution has an oxygen generating component, the alkaline stock solution contains a volatile alkaline component ( Claim 4 ), and the acidic stock solution and the alkaline stock solution react when discharged to exert an effect. Those containing the reaction components to be treated ( Claim 5 ) are preferred. Further, it is preferable that the acidic stock solution and the alkaline stock solution are hair dyes or decoloring agents ( claim 6 ).
The double aerosol product of the present invention is filled with a pressurizing agent in the space between the outer container and the inner bag of any of the aforementioned packaged products ( Claim 7 ).

In the packaged product of the present invention (Claim 1), the inner bag is filled with an aqueous ammonia solution having a pH of 11 to 13 in one storage part, and water such as purified water or ion exchange water is supplied to the remaining storage part. Since it has a barrier function in which the pH change of water is less than 3 after 1 month at 25 ° C. in a filled state, the inner bag prevents permeation of gases such as ammonia and oxygen, and has high reactivity. However, it is preferable because it can be stably stored for a long time. When the pH change of the water exceeds 3, the barrier function becomes insufficient, and the amount of gas such as ammonia and oxygen that permeates through the inner bag increases, and the reaction components in the contents start the reaction in the inner bag. The oxidant is easily decomposed and the effect tends to be reduced. The stability of the contents and the safety of the container are likely to decrease, such as the outer container being easily corroded. Further, since the inner bag is partitioned into a plurality of storage portions by the partition element, a plurality of contents can be stably sealed and stored in one outer container. Furthermore, since the inner bag is divided vertically, when filling a plurality of contents, the position of the filling nozzle of the contents and the opening of the inner bag may be the same as the conventional filling line, etc. It is preferable in terms of ease of operation.

Also, even if the stock solution consisting of the alkaline stock solution and an acidic solution (claim 2), in particular, pH difference of the alkaline stock solution and acid stock solution at 25 ° C. is 5 to 10 A (claim 3) Can be stored for a long period of time while maintaining a high effect without reacting them.

In addition, even when the acidic stock solution has an oxygen generating component and the alkaline stock solution contains a volatile alkaline component ( Claim 4 ), oxygen and ammonia can be confined in each storage section. The pH fluctuation of the water content is small, and progressive reaction or decomposition of the contents can be prevented.
Further, even when the acidic stock solution and the alkaline stock solution contain a reaction component that reacts and exerts an effect when discharged ( Claim 5 ), the reaction component does not react in the inner bag for a long period of time. Can be saved.
When a pressurizing agent is filled in the space between the outer container and the inner bag of any of the above-described packaged products ( Claim 7 ), it can be used as a double aerosol product and the contents can be easily discharged. preferable.

The inner bag neck portion 3b is provided with a flange portion at the upper end, and the inner bag bottom portion 3c closes the lower end of the body portion.
The radius of the constricted portion 71 is smaller than that of the body portion 3 a, and the upper and lower storage portions 27 and 26 are formed in a tapered shape toward the constricted portion 71. Thereby, the upper and lower storage parts 27 and 26 are easily contracted with the discharge of the contents, and the remaining amount of the contents can be reduced. Further, the lower portion of the lower storage portion 26 is formed in a tapered shape so that the bottom area decreases toward the bottom 3c. This is preferable because the inner bag can be easily stored in the outer container.

  Since the inner surface of the inner bag used in the packaged product of the present invention is in contact with both the acidic stock solution and the alkaline stock solution, it is preferable to provide a polyolefin or fluororesin that is stable to both the acidic stock solution and the alkaline stock solution in the innermost layer. An auxiliary layer may be provided on the innermost surface.

  When a synthetic resin is used as a component constituting the inner bag, it can be molded by blow molding or the like.

  The partition wall member 72 is closely fitted into the constricted portion 71, protrudes from the upper surface of the main body 4 having a bottomed cylindrical shape, a flange portion 4a formed in a tapered shape at the upper portion of the main body, and the inner surface of the upper end. Is formed of a cylindrical engagement portion 4b that fits closely with the tube 5, and the lower side surface 4c of the main body is tapered downward. The lower side surface 4c is provided with an annular protruding portion 6 that protrudes radially outward and engages with the constricted portion. The annular projecting portion 6 and the constricted portion 71 are engaged with each other, and the separation of the partition wall member 72 from the constricted portion 71 is prevented. Thus, when the partition member 72b is fitted into the constricted portion 71 in a state where the tube 5 is inserted, the lower storage portion 26 of the inner bag is completely sealed except for the tube 5.

  Moreover, as a material for the partition member, polyacetal, polyamide, polyolefin, polyphenylene sulfide, synthetic resin such as fluororesin, metal such as stainless steel, synthetic rubber, rubber such as silicone rubber, fluororubber, or the like can be used. Thereby, deterioration of a partition member can be prevented and permeation | transmission and communication between the upper and lower storage parts which arise by deterioration of a partition member can be prevented. In order to prevent gas such as ammonia and oxygen from permeating through the gap between the partition member and the inner bag, an elastic body such as fluororubber is provided on the synthetic resin or metal on the outer peripheral surface of the partition member, or deterioration due to the contents. The entire coating may be applied to prevent it.

  For example, as shown in FIG. 5, the valve 13 b includes a mounting cup 45 that is crimped to the bead 17 of the outer container 11, a housing 46 that is held at the center of the mounting cup, and a housing 46 that is movable up and down. The stem 47 having two stem holes 47a and 47b, the stem rubbers 49a and 49b fitted to the stem holes 47a and 47b in the housing, and between the stem rubbers, near the outer peripheral ends of the respective stem rubbers A cylindrical fixing member 20 for fixing the stem and a spring for constantly urging the stem upward.

With this configuration, the inside of the housing includes the inner wall of the housing 25, the lower storage portion 25 a partitioned by the stem 14 and the lower stem rubber 49 a, the upper and lower stem rubbers 49 a and 49 b, and the fixing member 20. And an upper storage section 25b partitioned by
The housing 25 is provided with communication holes 48a and 48b on its side and bottom.

  The stem 14 has two discharge holes and stem passages 18a and 18b that are independent of the discharge holes. The stem passages communicate with the lower and upper stem holes 47a and 47b, respectively. Each storage unit communicates with the lower and upper storage units 25a and 25b.

  Returning to FIG. 1, the tube 5 is fitted in the lower part of the housing of the double aerosol container 1, and the cylindrical projection 7 is fitted into the engagement member 74. Further, a gasket is provided on the lower inner surface of the protrusion 7 to seal between the tube 5 and the housing 25 and prevent the tube 5 from falling off.

  The engaging member 74 has a cylindrical shape in which a protruding portion of the valve is fitted and the lower opening 8 opens downward in a tapered shape. When the tube 5 fitted into the partition wall member 72 is attached to the valve 13b by the engagement member 74, the tip of the tube 5 is simply aligned with the lower opening of the engagement member, and the tip of the tube 5 is at the lower end of the valve. Guided by the protrusion 7, the tube 5 can be easily attached to the valve.

  The tube 5 is fitted into the protruding portion 7 of the housing 46 and extends downward, and is made of metal (for example, stainless steel) or synthetic resin having corrosion resistance to the contents. A synthetic resin film may be provided on the outer surface and / or the inner surface of the metal tube. Thereby, a packaged product can be used up without each content mixing.

  The discharge member 2 includes a valve engaging portion 2b having two communication holes 2a, two injection holes 2c, and a discharge member inner passage 2d that connects the communication holes 2a and 2c. Thus, when the discharge member is operated to open the valve 13b, the contents separately injected from the valve stem are discharged independently without mixing.

  The double aerosol container 1 is filled with the content A in the lower storage portion 26 of the inner bag, the partition member is inserted into the constricted portion, the lower storage portion is blocked except for the passage, and the content is stored in the upper storage portion 27. The container B is filled, the valve is placed on the opening of the inner bag, the opening of the upper storage is closed, and the space between the outer container 11 and the inner bag 12 is filled with the pressure agent C. Filling by cup filling or the like, fixing the valve to the outer container, and mounting the discharge member 2 on the stem 47, a double aerosol product 1a is obtained. Thereby, the 1st content A and the 2nd content B can be filled at high speed, and the working efficiency is high. Further, a pressure agent filling valve may be provided at the bottom of the outer container 11 or the like.

  The double aerosol product of FIG. 1a manufactured as described above has a pressurized agent such as compressed gas or liquefied gas and a mixed gas of compressed gas and liquefied gas filled between the inner bag 12 and the outer container 11 inside. The bag 12 is constantly pressurized. Therefore, an internal pressure is generated in the inner bag 12. Examples of the compressed gas include nitrogen gas, carbon dioxide gas, nitrous oxide gas, compressed air, and a mixed gas thereof. Examples of the liquefied gas include liquefied petroleum gas, dimethyl ether, chlorofluorocarbons, and mixed gas thereof. Furthermore, pressure adjusting components such as pentanes can be used as necessary. When the discharge member is operated in this state and the valve 13 is opened, the pressure in the housing 46 becomes substantially the same as the external atmospheric pressure. When using a valve that mixes in the housing 46 (for example, FIG. 3a), The first content A enters the housing 46 through the tube 5 from the lower storage portion 26 of the Twelve. At the same time, the second content B enters the housing 46 from the upper storage portion 27 of the inner bag 12 through the communication hole 48. And both are mixed in the housing 46, or it discharges outside from the discharge hole etc. of a discharge member, maintaining a layer state.

  When the contents A and B are discharged, the pressure applied to the lower storage portion 26 and the pressure applied to the upper storage portion 27 are substantially the same. Therefore, only one side is discharged and the other remains, or the amount of discharge of each content is different, so that the active ingredient cannot be reacted at a predetermined mixing ratio and the effect cannot be obtained sufficiently. There are few problems when pressure is applied. Further, in the embodiment shown in FIG. 1, the constricted portion 71 of the inner bag 12 is narrower than the upper cylindrical portion, and the communication hole 48 communicates with the upper portion of the upper storage portion 27. When the remaining second content B of 27 is reduced, the upper storage portion 27 is crushed upward from the constricted portion 71 in order. Similarly, the constricted part 71 of the inner bag 12 is thinner than the lower cylinder part, and the first contents A in the lower storage part 26 are discharged in order from the opening at the lower end of the dip tube 28. The lower storage portion 26 is crushed downward from the constricted portion 71 in order. Therefore, there is little possibility that the contents A and B remain in the inner bag 12. Further, since the contents A and B are further isolated when they are used, the contents A and B can be stored without further mixing.

The contents filled in the inner bag of the present invention can be stable even if the contents are filled in one outer container, but the contents react with each other by contact, mixing, etc. It can be filled with reactive contents to be exhibited.

Among the alkali agents, it is preferable to use amines from the viewpoint that an excellent finish is easily obtained, and among the amines, amines having volatility such as ammonia from the point that odors are easily lost after being used for hair. It is preferable to use it.

  Examples of the solvent include water, alcohols, and mixtures thereof. Examples of the water include purified water, ion-exchanged water, and physiological saline.

The pH of the alkaline stock solution at 25 ° C. is preferably 8 to 12, and more preferably 8.5 to 11. When the pH is less than 8, the storage stability of an active ingredient such as an oxidation dye is deteriorated, and a desired effect is hardly obtained at the time of use. On the other hand, when the pH exceeds 12, the inner bag becomes difficult to withstand when stored for a long period of time, reacts with the acidic stock solution filled in other storage parts, corrodes the inner surface coat of the outer container, Safety may decrease due to disassembly.

Examples of the acidic stock solution include those obtained by dissolving or dispersing an oxidizing agent such as hydrogen peroxide and oxidase, a stabilizer, a pH adjuster, and the like in a solvent.
When hydrogen peroxide (oxygen generating component) is used as the oxidizing agent, the blending amount is preferably 0.1 to 10% by weight, more preferably 1 to 6% by weight in the acidic stock solution. When the amount of hydrogen peroxide is less than 0.1% by weight, the oxidizing power is insufficient and it is difficult to obtain a good hair dyeing effect. When the amount exceeds 10% by weight, the hair and scalp are damaged and the outer container is corroded. It tends to have an adverse effect such as pressure rise.

When an oxidase is used as the oxidant, examples of the oxidase include laccase, peroxidase, uritase, catalase, tyrosinase and the like. The amount of the oxidase is 0.001 to 20% by weight in the second agent, and further 0 It is preferable that it is 0.01 to 10 weight%. When the blending amount of the oxidase is less than 0.001% by weight, the oxidizing power is insufficient and it is difficult to obtain a good hair dyeing effect. It is an economy.

The pH of the acidic stock solution at 25 ° C. is preferably 1.5 to 6, and more preferably 2 to 5. When the pH is less than 1.5, the acidic component easily permeates through the inner bag when stored for a long period of time, and reacts with the alkaline stock solution filled in other storage units to reduce the effect of the active component. , May reduce the stability of the contents. In addition, the inner surface coat of the outer container may be corroded to reduce safety. On the other hand, if the pH exceeds 6, the reactivity with the active ingredient in the alkaline stock solution may decrease and the effect may be reduced.

  The difference in pH between the acidic stock solution and the alkaline stock solution is 5 to 10, more preferably 6 to 9 because the active ingredient is stably stored and reacts effectively when discharged, and the desired effect is easily obtained. Preferably there is.

  The content to be filled in the packaged product of the present invention is not limited to the above hair dye, and the same content may be used. However, the inner bag used for the packaged product of the present invention can be filled with different types of contents from the viewpoint that the contents can be stably stored with less contact and gas permeability between the storage units. . The contents different from each other include the active ingredient of the contents (source liquid) filled in each storage unit, the amount of the ingredients, the ingredients such as the solvent, the form of the contents such as liquid, gel, and cream. (Including those having different viscosities), and the state of contents (appearance of contents such as color tone and transparency) such as homogeneous and heterogeneous systems, emulsions, and dispersions.

Since the packaged product of the present invention fills the above-mentioned contents into a packaging container having a plurality of compartments separated from each other, the contents are in contact with each other when the contents are filled in the compartment. Or mix. In addition, even the contents that can generate gas can be stored stably with a small amount of gas permeation, so the contents to be filled in each storage unit can be contacted or mixed between the contents during or after discharge. It is possible to use a combination of reaction components that react or exhibit effects or are activated. In addition, since the contents can easily be dissolved or mixed together, the reaction components can easily react at the time of discharge or after discharge, and the effect can be easily obtained.
Examples of reactions that occur when the contents are brought into contact with each other include neutralization reactions, hydration reactions, oxidation / reduction reactions, ion exchange reactions, dissolution, decomposition, and the like. In addition to the coloring (discoloration, decoloring) of the hair dye described above, heat generation, cooling, thickening, film formation, foaming, antiperspirant and the like can be mentioned.

  Examples of the combination of the reaction components for the neutralization reaction include a water-soluble polymer and a pH adjuster (acidic component or alkaline component), such as a carboxyvinyl polymer and an alkaline component, an acrylic acid / slealess copolymer, and an acrylic acid / cetes copolymer. Examples of the polymer include an alkali component, an acrylic acid / aminoacrylic acid / PEG / alkyl (carbon number 10 to 20) copolymer, and an acidic component.

The effect of improving the sustainability of the cooling feeling can be obtained.

  Examples of the combination of the reaction components that undergo the hydration reaction include polyhydric alcohols such as glycerin, diethylene glycol, and propylene glycol, and water, inorganic powders such as silicic anhydride, zeolite, sodium carbonate, and potassium carbonate, and water. It is done. These are used for applications such as humectants, cleansing agents, pack agents, shaving foams, etc., and can provide a warm feeling due to heat of hydration.

  Examples of the combination of reaction components that undergo oxidation / reduction reaction include dyes such as paraphenylenediamine and oxidizing agents such as hydrogen peroxide and oxidase, sodium sulfite and hydrogen peroxide, sodium thiosulfate and hydrogen peroxide, and the like. . These are used for hair dyes, moisturizing creams, cleansing agents, packs, shaving foams and the like, and can obtain effects such as hair coloring by color development (discoloration), blood circulation promotion by fever, and skin softening.

  Examples of the combination of the reaction components that undergo the ion exchange reaction include sodium alginate and calcium lactate. These are used for the formation of a protective film, food, amusement equipment, and a favorite product, and can obtain a film forming effect.

  Examples of the combination of the reaction components to be dissolved include urea and water, (anhydrous) calcium chloride and water, and chlorohydroxyaluminum and water. In the case of a combination of urea and water, it is used for applications such as anti-itching, emollient, exfoliating agent, ointment and the like, and a cooling effect due to heat absorption can be obtained. In the case of a combination of (anhydrous) calcium chloride and water, it is used for applications such as a moisturizing agent, a cleansing agent, a pack agent, a shaving foam, a treatment agent, etc., and a thermal feeling can be obtained. In the case of chlorohydroxyaluminum and water, it is used as an antiperspirant, and when chlorohydroxyaluminum is dissolved in water, it is ionized to exert an antiperspirant effect.

  Examples of the combination of the reaction components that undergo the decomposition reaction include carbonates such as sodium hydrogen carbonate, sodium carbonate, potassium hydrogen carbonate, and potassium carbonate, and acids such as citric acid, tartaric acid, and phosphoric acid. When dissolved in the aqueous solution, the carbonate is decomposed to generate carbon dioxide, and the foaming effect can be obtained by blending with a foaming agent such as a surfactant. These are preferable for hair cosmetics, human cosmetics, quasi-drugs, pharmaceuticals, etc., but their uses are not particularly limited. In addition, the blood circulation promotion effect by the generate | occur | produced carbon dioxide gas is also acquired, and it can use suitably as a hair restorer.

  The reaction components are blended into different contents so that the reaction components do not react with each other when the contents are filled in the storage unit. Specific examples of the contents include, for example, JP-A-10-45547, JP-A-10-287534, JP-A-2001-2537, JP-A-2001-288055, JP-A-2001-294519, Hair dyes described in JP-A-2001-181159 and Japanese Patent Application No. 2002-367294, enzyme hair dyes described in JP-A-63-46313, JP-A-6-172145, and JP-A-7-173033 Cleansing as described in JP-A-6-336413, JP-A-8-268828, JP-A-2001-19606, etc., JP-A-11-228332, JP-A-11-279031 Treatment agents described in Japanese Patent Publications, shaving compositions described in Japanese Patent Publication No. 45-19996, etc. No. 003-19481, exothermic composition according such Hei 10-306276 JP, and the like.

  The form of the contents is not particularly limited, such as liquid, gel, cream, or paste, but the contents are in contact with each other between the inner bag storage parts (partition wall part), the valve housing, or the discharge passage. The reaction can be prevented when unnecessary, and the decrease in the effect of the reaction components can be reduced. The one having a viscous content is preferable. The viscosity of the content is preferably 100 cp or more, more preferably 1000 cp or more. When the content is 100 pc or less, it is difficult to obtain the effect of preventing the movement of reaction components due to fluidity. Further, in order to facilitate discharge of each content at a predetermined discharge amount ratio, the viscosity ratio of each content is preferably 5: 1 to 1: 5.

The contents may be in a homogeneous system in which an active ingredient is dissolved in a solvent, a heterogeneous system in which an oil component and a water component are separated, or a water-in-oil type or oil-in-water in which an oil component and a water component are emulsified. In order to make it easier to obtain the effect, the reaction components in each content easily react at the time of discharge or after discharge. Those having a small specific gravity difference between the contents and those in which the contents (solvents) are easily dissolved or mixed are preferred.
The filling ratio of the contents is 5: 1 to 1: 5 in terms of volume ratio and 4 because the adjustment of the discharge amount of each content is easy and the reaction components easily react and easily exert the effect. : It is preferable that it is 1-1: 4.

As a particularly preferable example of filling the packaging container of the present invention described above, a two-component reactive hair dye is given. However, a two-component reactive heat generation comprising a first agent containing an exothermic component and a second agent containing water. It can be suitably used for a preparation.
As the first agent, an exothermic component (for example, magnesium chloride, zeolite, etc.) that generates heat by being dissolved in water or hydrated with water is an oily base (for example, hydrocarbon such as liquid paraffin, ester oil, silicone oil, etc. Oily preparations dispersed in a liquid oil).
Further, in the first agent, a surfactant (for example, a nonionic surfactant) for dispersing the exothermic component, a foaming component (for example, a carbonate such as sodium hydrogen carbonate, sodium carbonate), a thickener. (For example, dextrin palmitate etc.) may be blended.

  Examples of the second agent include water-containing preparations such as water, cream (water-in-oil emulsion), and aqueous gel. In order to maintain the exothermic effect, a second agent in which a hydrophilic surfactant is dispersed in the oil base may be used. Furthermore, when carbonate is contained as a foaming component in the first agent, it is preferable to mix an acid (for example, citric acid) for decomposing the carbonate and generating carbon dioxide gas.

  In addition to the above-mentioned components, both the first agent and the second agent are effective ingredients (for example, treatment agents, moisturizers, ultraviolet absorbers, amino acids, vitamins, extract extracts, Preservatives, cleaning agents, fragrances, etc.), foaming agents (eg, liquefied petroleum gas, isopentane, etc.) can be blended. In the case of a two-component reaction type exothermic preparation, moisture in the second agent may permeate through the inner bag and react with the exothermic component in the first agent, but the inner bag used in the packaging product of the present invention is excellent. In addition, since it has a barrier function, it can prevent moisture permeation and can be stored stably for a long period of time without reducing the heat generation effect.

  2a and 2b show another embodiment in which the packaging container of the present invention is applied to an inner bag type double aerosol container 10. FIG. The double aerosol container 10 includes a rigid outer container 11, a flexible inner bag 12 accommodated in the outer container, and a valve 13 attached to the opening of the outer container 11 (see FIG. 2b). And. A conventionally well-known thing can be used for the outer container 11 similarly to the said embodiment.

  The inner bag 12 is configured to be openable and closable so as to take a state (FIG. 2a) in which the central portion 21 communicates with the upper and lower sides (FIG. 2a) and a state where the central portion 21 is blocked (FIG. 2b). Other materials of the inner bag 12 are substantially the same as those of the inner bag 12 of FIG.

  The inside of the inner bag 12 is divided into a lower storage portion 26 and an upper storage portion 27 via a central portion 21. When the central portion 21 is closed as shown in FIG. 2b, the upper and lower storage portions 27, 26 are separated. The two are substantially blocked except for the dip tube 28 provided in the valve 13. The dip tube in the packaging container having the upper and lower storage portions is a part of a passage that connects the lower storage portion and the valve, and connects the lower storage portion and the outside, and is made of synthetic resin or metal. It doesn't matter.

  In this embodiment, the openable and closable configuration of the central portion 21 includes a plurality of inverted triangular bent pieces 32 that are continuous with the lower end of the upper cylindrical portion 30 via a bending line 31 and a lower cylindrical portion 33. A triangular bent piece 35 that is continuous to the upper end of the bent piece 34 via a bend line 34, and a bellows-like cylindrical portion 36 provided between the bent pieces 32, 35. The tips of the upper bent piece 32 and the lower bent piece 35 face each other. The upper end of the bellows-like cylindrical portion 36 has a sawtooth shape that is continuous through the oblique side of the upper triangular bent piece 32 and the folding line 31. Similarly, the lower end has a saw-tooth shape that is continuous via the bevel line 34 and the oblique side of the lower triangular bent piece 35. In the bellows-shaped cylindrical portion 36, the vertical line connecting the tips of the upper and lower triangles is a mountain fold fold line 40, and the vertical line connecting the upper and lower triangle bases is a valley fold fold line. 41. Therefore, as shown in FIGS. 2c and 2d, the bellows-like cylindrical portion 36 is foldable by alternately arranging mountain fold fold lines 40 and valley fold fold lines 41.

  When the inner bag 12 configured as described above is extended as shown in FIG. 2a, the upper and lower triangular bent pieces 32 and 35 extend downward and upward, and the bellows-like cylindrical portion 36 is shown in FIG. 2c. As shown in the figure, it has an open star shape. Therefore, the center has a large opening, whereby the lower storage portion 26 and the upper storage portion 27 of the inner bag 12 communicate with each other. On the other hand, when the flange 24 of the inner bag 12 is pushed downward in the axial direction of the container or after the valve is crimped by filling the contents, the upper triangular shape is contracted as shown in FIG. The bent piece 32 and the lower triangular bent piece 35 are bent inward, respectively, so that the top and bottom are cut off except for the center as shown in FIGS. 2b and 2d. At that time, the bellows-like cylindrical portion 36 exhibits a folded star shape (FIG. 2 d) while allowing inward deformation of the bent pieces 32, 35, leaving the dip tube 28 as described above and below. Close in direction almost tightly. In FIG. 2d, for easy understanding, a gap is formed between the vertical pieces of the cylindrical portion 36. Further, when the bellows-like cylindrical portion 36 is contracted as shown in FIG. 2b, the fold line 40 of the mountain fold is also pulled inward while being compressed up and down, so that it is bent inward while being bent left and right.

  2b, the valve 13 is accommodated in a mounting cup 45 that is crimped to the bead 17 of the outer container 11, a housing 46 that is held in the center of the mounting cup, and is movably accommodated in the housing 46. As shown in FIG. Stem 47, a spring (not shown) that constantly biases the stem upward, and the above-described dip tube 28 extending downward from the lower end of the housing 46. The valve 13 is substantially the same as the conventional valve except that a communication hole 48 communicating with the upper storage portion 27 of the inner bag 12 is provided at the lower portion of the housing 46. That is, the mounting cup 45 has a curved flange 50 that is crimped to the bead 17 via the flange 24 and the gasket 49 of the inner bag 12, and a bottomed cylindrical housing holding portion 51 that holds the housing 46. The mounting cup 45 is made of a metal plate such as aluminum or tinplate.

  The housing 46 is a substantially bottomed cylindrical plastic part, and a valve rubber (not shown) for opening and closing the stem hole of the stem 47 is interposed between the upper end of the housing 46 and the lower surface of the mounting cup 45. ing. A conventionally well-known thing can be employ | adopted for the stem 47, a spring, and a valve rubber. The housing 46 communicates with the lower storage portion 26 of the inner bag 12 through the dip tube 28, and communicates with the upper portion of the upper storage portion 27 of the inner bag 12 through the communication hole 48. That is, the dip tube 28 and the communication hole 48 are a part of a passage that communicates each storage portion with the outside. By adjusting the length and size of the passage, the flow rate from each storage unit can be controlled, and the discharge amount of the contents filled in each storage unit can be adjusted to an appropriate ratio. As the dip tube 28, a metal (for example, stainless steel) or a synthetic resin having high corrosion resistance and non-permeability to the contents is used, or the surface of which is coated with such a synthetic resin is preferable. Thereby, a dip tube does not react with the contents with which the upper and lower storage parts were filled. Further, the lower contents remaining in the dip tube 28 and the contents in the upper storage portion 27 outside the dip tube 28 do not penetrate through the dip tube 28 and are not mixed or reacted. .

  Further, as a valve used in the aerosol product of the present invention, a valve 13a with a check valve shown in FIG. 3a, a valve 13b shown in FIG. 4a, a valve 13c shown in FIG. 5a, and a valve 13d shown in FIG. 6a may be used. . The housing 46a of the valve 13a of FIG. 3a has a pair of communication holes 48a and 48b at the lower end, and the one communication hole 48a is stored under the inner bag through the dip tube 28 engaged with the dip tube engaging portion 55. The other communication hole 48 b communicates directly with the upper storage portion 27 of the inner bag 12. A check valve 51a is provided above the communication holes 48a and 48b. The check valve 51a includes a ball 53 installed at the upper part of the communication holes 48a and 48b, and a spring 52 that presses the ball 53 against the communication hole to close it.

  When a discharge member such as an injection button or spout inserted into the stem 14 is pushed down to open the stem hole 47a, it communicates with the outside air. The ball 53 urged by the spring 52 is pushed up by the pressure applied by the pressure agent, and is discharged from the ejection hole of the ejection member via the stem hole and the stem. Further, in a normal state, the ball 53 is urged downward by the spring 52 and closes the communication hole, so that the contents mixed in the housing 46a do not flow backward to each storage portion. In this way, the check valve 51 allows the flow from each storage portion to the valve and prevents the flow from the valve to the storage portion. As a result, the contents once mixed in the housing 46a can be prevented from returning to the storage unit (see FIGS. 3a and 3b). In the valve 13a, the contents A and B stored in the upper and lower storage portions are mixed in the valve housing 46a. Therefore, the passages from the storage portions to the communication holes 48a and 48b of the valve are independent from each other, and the passages from the communication holes 48a and 48b to the outside are shared.

  The valve 13b shown in FIG. 4a includes a housing 25, a stem 14 having two stem holes 47a and 47b slidably received in the housing, and a stem that fits with the stem holes 47a and 47b in the housing. Rubber 49a, 49b, and a cylindrical fixing member 20 provided between the stem rubbers, for fixing the vicinity of the outer peripheral end of each stem rubber. With this configuration, the inside of the housing includes the inner wall of the housing 25, the lower storage portion 25 a defined by the stem 14 and the lower stem rubber 49 a, the upper and lower stem rubbers 49 a and 49 b, and the fixing member 20. And an upper storage section 25b partitioned by Further, the stem 14 has passages 18a and 18b that are independent from each other, and these passages communicate with the respective storage portions through the lower and upper storage portions 25a and 25b through the lower and upper stem holes 47a and 47b. ing. In other words, by pushing down the stem 14 and opening the stem holes 47a and 47b, the contents of the lower storage part are stored from the lower storage part through the dip tube 28 and the communication hole 48a at the lower end of the housing to the lower storage part 25a. Then, the contents in the upper storage portion are stored from the communication hole 48b to the upper storage portion 25b. Further, these contents go to the discharge holes through the stem holes 47a and 47b and the in-stem passages 18a and 18b, respectively. Thus, by using this valve 13b, the contents of the upper and lower storage portions can be discharged simultaneously without being mixed in the valve 13b. In other words, by using the valve 13b, each passage communicating from the storage portion to the outside is independent. This is because the contents of the upper and lower storage parts of the aerosol product of the present invention react when they are mixed together, and when the curing, heat generation, endotherm, discoloration, etc., or even if there is no reaction, the contents exhibit different colors. It is particularly effective and preferable when the two liquids are easily mixed, for example, a combination of contents having excellent compatibility such as water and alcohol, or a combination of contents having a small specific gravity difference (FIG. 4a). , See FIG. 4b).

  Further, the valve 13c of FIG. 5a has a single passage in the stem 14, and the contents are respectively pushed into the stem holes 47a and 47b through the storage portions 25a and 25b from the storage portions. It is a valve configured to be mixed at Other configurations are the same as the valve 13b of FIG. 3a. Thereby, since the contents are mixed in the stem 14, the mixed contents do not flow back into the valve, and the contents can be stably stored for a long period of time. 5a and 5b show the open / closed state of the valve 13c which is substantially the same as the valve 13c.

  The valve 13d shown in FIG. 6A includes a housing 25, a stem 14 having a stem hole 47a slidably received in the housing, and a cylindrical intermediate seal member 20a fitted between the inner wall of the housing and the stem. And a stem rubber 49a which is provided on the intermediate seal member and engages with the stem hole 47a, and a mounting cup 49c which is fixed to the outer container by crimping them to the outer container. Moreover, the housing 25 has communication holes 48a and 48b communicating with the upper and lower storage portions. As a result, the stem hole 47a is normally closed by the stem rubber 49a, and the contents of the upper storage portion flowing from the communication hole 48b are sealed by the inclined surfaces of the intermediate seal member 20a and the stem 14, and the inner side of the intermediate seal member 20a. It is configured not to flow into. By lowering the stem 14 and opening the stem hole 47a, the contents filled in the lower storage portion reach the inner storage portion 25a through the dip tube 28 and the communication hole 48a at the lower end of the housing, and head toward the stem hole 47a. On the other hand, the contents filled in the upper storage portion go directly to the stem hole 47a from the communication hole 48b and the passage 48c on the side wall of the housing. At this time, the passage 48c and the storage portion 25a are continuous, but the content flows upward due to the pressure gradient generated by the pressurizing agent, and does not flow backward to the communication holes 48a and 48b. As a result, the upper and lower contents merge and mix at the stem 14. Here, the passage 48c and the storage portion 25a are substantially independently connected to the upper and lower storage portions, and serve as storage portions for storing the respective contents (see FIGS. 6a and 6b). Therefore, when the stem 14 of FIG. 4a is used as the stem, the contents filled in each storage unit from each storage unit to the outside are not mixed, and each passage through which each storage unit communicates with the outside is provided. being independent. In addition, although the dip tube 28 showed the example which inserts a dip tube in the outer side of the cylindrical part of a housing lower part, the other insertion method as based on another Example may be sufficient.

  Next, as a discharge member used in the aerosol product of the present invention, a conventional spout or a member with a nozzle can be used, but the discharge members 29a, 29b, and 29c shown in FIGS. 7a, 7b, 7c, and 7g. 29e, and the discharge member 29d shown in FIG. 8 can be used. The discharge members 29a, 29b, 29c and 29e in FIGS. 7a to 7c and FIG. 7g are preferable when used with a valve (for example, the valve 13b in FIG. 4) from which each content is discharged independently, and the discharge member 29d in FIG. In addition to the valves for discharging the contents independently, valves for discharging the contents in a mixed state in the valves (eg, the valve 13a in FIG. 3a, the valve 13c in FIG. 5a, and FIG. 6a). The valve 13d) can be used.

  The discharge member 29a in FIG. 7a has a cylindrical shape with a partition wall provided at the center, and the discharge material 30a having a stripe shape in cross section can be obtained by passing the contents therethrough (see FIG. 7d). Moreover, the discharge member 29b of FIG. 7b is a cylindrical thing concentrically divided into two layers, and the discharge material 30b having a two-layer cross section can be obtained by passing the contents therethrough (see FIG. 7e). ). Furthermore, the discharge member 29c of FIG. 7c is a cylindrical member having a peripheral portion partitioned, and a discharge product 30c having a cross-section pattern can be obtained by passing the contents therethrough (see FIG. 7f). Moreover, the discharge port 47 may be tapered like the discharge member 29e of FIG. 7g, and may be a spatula shape.

  Further, the discharge member 29d shown in FIG. 8 has a support portion 42a engaged with the bead portion of the valve, a trunk portion 42 provided continuously on the support portion, and a vertical interval from the side surface of the trunk portion. A plurality of branch portions (comb teeth) 43a provided at the bottom, a stem engaging portion 42c provided on the bottom surface of the trunk portion 42, and an opening portion 54 for passage cleaning provided at a lower portion of the trunk portion. Comb type with The trunk portion 42 includes a passage 42b provided in a straight line from the stem engaging portion 42c to the top surface, a plurality of discharge holes 43 arranged at equal intervals on the side wall, and a plurality of passages connecting the passage 42b and each discharge hole 43 Passage 42d. Further, the branch portions 43a are arranged at equal intervals between the discharge holes 43 provided on the trunk side wall. As a result, the contents flow from the stem through the stem engaging portion 42 c to the passage 42 b and are discharged from the discharge holes 43. This is effective when used as a hair dye, treatment agent, styling agent or the like as the contents. In the aerosol product using the discharge member 29d, since the discharge hole 43 is provided at the base of the branch portion, the contents reach the hair naturally by combing the hair and can be applied evenly. The passage cleaning opening 54 is continuous with the passage 42b, and a conventionally known ball-type check valve 54a is provided in the vicinity of the opening. Further, cleaning means disclosed in Utility Model Registration No. 2567137 may be used. Therefore, during use, the contents do not leak from the passage opening 54 to the outside of the discharge member 29d. By providing such a cleaning means, when the contents remaining in the passage of the discharge member 29d after use are poured from the passage opening 54 with water or cleaning liquid, the residue in the discharge member 29d can be washed away. Furthermore, a coating apparatus disclosed in FIGS. 1 and 7 of JP-A-10-236539 may be used as a discharge member for the aerosol product of the present invention.

  The aerosol container 10 of FIG. 2 configured as described above fills the lower storage portion 26 with the first content A from the upper end opening of the inner bag 12, and then compresses the inner bag 12 downward to compress the central portion 21. Is closed, the lower storage portion 26 and the upper storage portion 27 are shut off, and the second content B is filled into the upper storage portion 27 from the upper end opening, and further, the inner bag 12 and the outer container 11 are filled by a method such as undercup filling. A double aerosol product (packaging product) is obtained by filling a propellant or a pressurizing agent in between and crimping the mounting cup 45 of the valve 13 to the outer container 11. Actually, the stem 47 further includes a push button or a spout, such as the discharge member 29a of FIG. 7a, the discharge member 29b of FIG. 7b, the evaporating member 29c of FIG. 7c, or the discharge member 29d of FIG. And complete with a cover.

  In the above-described manufacturing method, when filling the contents, after filling the lower storage portion 26 with the first contents A, the flange 24 of the inner bag 12 is pushed downward in the axial direction of the container, etc. Since the central part 21 is closed up and down, it is difficult to mix with the first contents A when the upper contents 27 are filled with the second contents B. Therefore, the 2nd content B can be filled at high speed, and work efficiency is high. In addition, when filling the 2nd content B, the dip tube 28 is not attached, but after filling the 2nd content B, the dip tube 28 is penetrated to the center of the center part 21. As shown in FIG. However, the central portion 21 may be closed after the dip tube 28 is inserted into the inner bag 12 and then the second content B may be filled. In that case, after filling the first contents A, only the dip tube 28 may be inserted first, and after filling the second contents B, the housing 46 may be attached to the upper end of the dip tube 28. The housing 46 and the mounting cup 45 may be attached to the upper end of the dip tube 28 so that the entire valve 13 is handled as a unit. Moreover, the center part 21 of the inner bag 12 shrink | contracts by the filling pressure when filling the 2nd content B in the upper storage part 27, and the dead weight of the filled 2nd content B, and the upper and lower storage parts 26 and 27 are made to shrink. If the strength of the central portion 21 is set so that it can be blocked, the contents, propellant or pressurizing agent can be filled, and the valve 13 can be crimped easily. Further, before filling with the pressurizing agent, in order to remove oxygen remaining in the outer container, it may be replaced with vacuum, inert gas or liquefied gas. Thereby, the content can be preserve | saved longer as an aerosol product.

  The double aerosol product of FIG. 2 configured as described above is similar to the packaged product of FIG. 1 in that the compressed gas or liquefied gas and the compressed gas and liquefied gas filled between the inner bag 12 and the outer container 11 are filled. A pressurizing agent such as a mixed gas constantly pressurizes the inner bag 12. Therefore, when the contents A and B are discharged, the pressure applied to the lower storage portion 26 and the pressure applied to the upper storage portion 27 are substantially the same. Therefore, the contents can be discharged efficiently, and an extremely large amount of contents do not remain on only one side of the storage unit.

  The aerosol container 60 of FIGS. 9a and 9b has a small body diameter, for example, 10 to 40 mm, and reduces the internal capacity in order to reduce the size of the product or to have the contents deteriorated due to poor stability of the contents. It can be suitably used for occasions. The outer container 11 of the aerosol container has an upper end that extends upward, and a concave groove 61 that protrudes radially inward from the upper end of the outer container 11 is formed. The valve mounting cup 45 is divided into a holding portion 63 for holding the housing 46 and a cover 64 for attaching the holding portion to the outer container 11. The holding part 63 has a flange 65 that engages with the upper end of the outer container 11 via the packing 62, and the lower end periphery engages with the upper part of the protrusion that appears on the inner surface side of the groove 61. Further, the cover 64 has a bottomed cylindrical shape, and the periphery of the vicinity of the lower end thereof is caulked in the concave groove 61. That is, in the case of FIG. 2, the curved flange 50 of the mounting cup 45 of the valve 13 is crimped to the bead 17 provided at the upper end of the outer container 11, but in the case of the aerosol container 60 of FIG. Is different in that respect. Furthermore, the upper end of the inner bag 12 extends upward in a cylindrical shape so as to be interposed between the upper end of the outer container 11 and the holding portion 63.

  An annular groove 65 a that engages with a protrusion on the inner surface side of the recessed groove 61 of the outer container 11 is provided near the upper end of the inner bag 12. Further, the central portion 21 of the inner bag 12 is not provided with a clear crease line as in FIG. 2a, and triangular concave portions are folded at the portions of the downward truncated cone 66a and the upward truncated cone 66b. Arranged to be the starting point. The cylindrical portion 66c between the two truncated cones 66a and 66b is not provided with a fold or a bellows. However, even if such a folding starting point is provided, when the inner bag 12 is compressed in the vertical direction, buckling occurs in the cylindrical portion 66c, and it is folded and closed. Other parts, for example, the entire form including the central part 21 of the inner bag 12 and the material and form of the outer container 11 are substantially the same as those of the double aerosol container 10 of FIG.

  Similarly to the case of FIG. 2, the double aerosol container 60 is also filled with the first content A in the lower storage portion 26 of the inner bag 12 and pressed on the upper end opening of the inner bag 12. After closing, the upper storage portion 27 is filled with the second content B, the inner bag 12 and the outer container 11 are filled with compressed gas and the like, and the valve is fixed, thereby providing an inner bag type double aerosol. A product is obtained (see FIG. 9b). And those filling operations are easy. The obtained double aerosol product is also used in substantially the same manner as the double aerosol product using the aerosol container of FIG. 2, while mixing the first content A and the second content B or in a layered state. It can be discharged.

  In the aerosol container 67 shown in FIG. 10, the inner bag 12 is provided with two openable / closable central portions 21, thereby providing upper, middle, and lower three storage portions 68 a, 68 b, 68 c. A through hole 69 communicating with the intermediate storage portion 68b is formed in the middle of the dip tube 28. The through hole 69 is preferably provided in the middle in the vertical direction of the middle storage portion 68b. Other parts are substantially the same as the aerosol product of FIG. 9b.

  In this case, by operating the valve 13, the first content A of the lower storage portion 68c enters the dip tube 28 from the lower end of the dip tube 28, and the second content B of the intermediate storage portion 68b passes through the through hole 69. It enters into the dip tube 28, and both rise together from that part and enter into the housing 46. Further, the third content C of the upper storage portion 68 a enters the housing 46 through the communication hole 48 of the housing 46. As a result, the three types of contents A, B, and C are discharged to the outside in a mixed state or while maintaining a layered state. The other points are substantially the same as the aerosol container 60 and the aerosol product of FIG. In addition, you may provide the two dip tubes of the dip tube 28 which connects the lower accommodating part 68c and the housing 46, and the short dip tube which connects the inner accommodating part 68b and the housing 46. FIG. In that case, the two contents B and C are not mixed in the dip tube.

  In the aerosol container 70 of FIG. 11a, the volume of the upper and lower storage parts of the inner bag 12 is different, the upper storage part 27 is larger than the lower storage part 26, and the volume ratio is about 4: 1. The volume of each storage unit can be arbitrarily set according to the volume of the contents to be filled and the ratio of the preferred discharge amount. However, since the discharge rate ratio can be easily adjusted by the hole diameter or length of the passage, The volume ratio is preferably 5: 1 to 1: 5. A constricted portion 71 smaller than the opening of the outer container 11 is provided in the middle of the inner bag 12. A partition wall member 72 that is closely engaged with the constricted portion 71 from above is attached around the dip tube 28. Thereby, even if the constricted part 71 itself does not open and close, it can be closed by the partition member 72. In this case, after the first content A is filled in the lower storage portion 26 of the inner bag 12, the dip tube 28 is inserted and the constricted portion 71 is closed with the partition wall member 72. Is cut off. Then, if the 2nd content B is filled into the upper storage part 27, the 1st content A and the 2nd content B will not mix. Therefore, this can also be filled with the second content B at high speed, and the working efficiency is high. In the present embodiment, the constricted portion is narrowed in a tapered shape, but may be uneven. However, the taper shape makes it easy to insert the partition member. In the aerosol container 70, the constricted portion may be thicker than other inner bag portions. In this case, the engagement between the partition member and the constricted portion can be made stronger and harder to disengage. Further, a longitudinal groove (not shown) is formed on the outer peripheral surface of the inner bag storage portion so that the inner bag is easily contracted. Are provided). Thereby, an inner bag can be shrunk efficiently and the remaining amount of contents after use can be selected.

  The partition member 72 may be made of an elastic member such as sponge or rubber, and a through-hole 73 for allowing the dip tube 28 to pass therethrough is openable and closable, and is always closed due to its elasticity. it can. In that case, after filling the first content A, only the partition member 72 is put in the inner bag 12 to close the constricted portion 71, and after filling the second content B in the upper storage portion 27, the dip tube 28 is inserted into the inner bag. 12 can be inserted into the through hole 73 of the partition wall member 72. In that case, since the valve 13 equipped with the dip tube 28 can be crimped to the outer container 11 later, the work can be performed almost in the same manner as the conventional one, and the working efficiency is high. The constricted portion 71 is made smaller than the opening of the outer container 11 in order to facilitate insertion from the opening of the partition wall member 72. When the partition member 72 is made of a flexible material such as sponge, The size of the constricted portion 71 is not particularly limited. Further, an O-ring may be provided inside the constricted portion or outside the partition member. This is preferable because the degree of sealing of the upper and lower storage portions is increased, and mixing of the contents of the upper and lower storage portions in the inner bag is further prevented. Moreover, you may provide an elastic body from the constriction part exterior. Furthermore, a step may be provided in the constricted portion and the partition member. Thereby, the constricted portion and the partition member are clip-fitted. Also in this case, the sealing degree of the upper and lower accommodation portions is increased, and the same effect as described above can be obtained.

  In the aerosol container 75 of FIG. 11b, the volume of the upper and lower storage parts of the inner bag is different from that of FIG. 11a, and the lower storage part is larger than the upper storage part. The partition member 72 is the same as the aerosol container 70 of FIG. 11 a except that the partition member 72 has a plug shape that fits deeply into the constricted portion 71. This has a high sealing property between the lower storage portion 26 and the upper storage portion 27. About another point, there exists an effect substantially the same as the aerosol container 70 of FIG. 11a.

  Further, the aerosol container 75a of FIG. 11c has a dip tube 28 whose length is up to the partition member 72, and an engagement member 74 that makes it easy to attach the dip tube 28 to the valve. The engaging member 74 is mounted on the housing and has a cylindrical shape. A lower opening into which the dip tube is inserted opens downward in a tapered shape. Accordingly, when the valve is placed on the container opening in the manufacturing process of the aerosol product, the tip of the dip tube is guided by the insertion port of the engaging member 74, and the dip tube can be easily attached to the valve. Moreover, the partition member and the dip tube can be fixed in advance with a high seal. Further, the engaging member 74 may be engaged with the inner bag as indicated by an imaginary line. Thereby, the contents of the upper storage portion can be completely isolated from the valve. This is preferably used when the contents of the upper storage part are highly corrosive to the mounting cup.

  In the aerosol container 70 of FIG. 11a, the aerosol container 75 of FIG. 11b, and the aerosol container 75a of FIG. 11c, the dip tube 28 is directly inserted into the partition member 72. However, like the aerosol container 75b of FIG. The lower end of the valve housing 46 may be closely connected with a tube 28a thicker than the dip tube 28, and the dip tube 28 may be inserted therein. In this case, the entire partition wall member 72 and the tube 28a, or the tube 28a itself having a thick portion whose lower end fits into the constricted portion 71 is a substantial partition wall member. When such a thick tube 28a is used, the upper end of the tube 28a comes close to the opening of the inner bag 12, so that the dip tube 28 can be easily inserted. The thick tube 28a may be extended to the vicinity of the bottom of the inner bag as indicated by an imaginary line. The upper end of the tube 28a can be fitted to the outer periphery of the lower end of the valve housing. In this case, a notch is provided in the tube 28a in the vicinity of the upper end of the tube 28a in accordance with the communication hole 48 provided in the side wall of the housing 46.

  As shown in FIG. 11f, the dip tube 28 itself can be provided with a thick portion 71b, and the thick portion can be fitted into the constricted portion 71 to block the upper and lower storage portions. In this case, the dip tube 28 becomes the partition member as it is. In any of the cases shown in FIGS. 11a to 11d, it is preferable to provide a lip seal 71a as shown in FIG. In these cases, the sealing performance between the upper and lower storage units is further enhanced. The lip seal 71a may be provided on the partition member 72 side. In the case of FIG. 11 c, the sealing performance between the engaging member 74 and the tube 28 can be improved by providing a similar lip seal 71 a on the tube 28 or the engaging member 74.

  Further, the partition members 72b and 72c shown in FIGS. 12a and 12c may be used. The partition member 72b of FIG. 12a is arranged in a cylindrical shape at a predetermined interval on a cylindrical body portion 150, a flange portion 151 formed in a tapered shape on the upper portion of the body portion, and a lower side surface of the body portion. The leg part 152 which has the hook part 153 which protruded to the radial direction outer side is provided in the edge part. Since the leg portions 152 are arranged in a cylindrical shape, the leg portions 152 exhibit elasticity in the radial direction. Therefore, the leg portions 152 are clip-fitted to the lower portion of the constricted portion of the inner bag. Thereby, the partition member 72b is fixed by the constricted portion, the leg portion 152, and the flange portion 151. That is, when the partition member 72b is fitted with the dip tube inserted, the lower storage portion of the inner bag is completely sealed except for the passage of the dip tube. As an inner bag to be engaged with such a partition member 72b, a flange may be provided at the lower part of the constricted portion of the inner bag so as to be easily engaged with the hook portion of the partition member (see FIG. 12b). Furthermore, in the present embodiment, the body of the partition wall member 72b is a cylinder, but may be a tapered truncated cone that narrows downward. In this case, the inner surface of the constricted portion of the inner bag is also tapered with the same inclination. Thereby, when inserting a partition member, the clearance gap between a constriction part and a partition member is small, and the sealing degree of the upper-and-lower storage part of an inner bag becomes stronger.

  The partition member 72c of FIG. 12c protrudes from the upper surface of the main body 160 having a bottomed cylindrical shape, a taper shape on the upper portion of the main body, and is slidably fitted to the lower end of the dip tube. And a communication hole 163 communicating with the inside of the engagement part 162 is provided at the center of the upper surface of the main body. The main body has an O-ring 164 in the center of the outer peripheral surface, and the inner surface is closed in a tapered shape toward the communication hole 163. By having the O-ring 164 in this way, the constricted portion of the inner bag and the partition member 72c are sealed. In this way, the partition member 72c is fixed by the O-ring 164 in the upward direction and fixed by the O-ring 164 and the flange portion 161 in the downward direction. Moreover, since the partition member inner surface is closed in a tapered shape, the flow of the contents is smoothed and clogging due to them is prevented. In this embodiment, an O-ring is used as a seal between the constricted portion and the partition member. However, a protrusion projecting radially outward on the outer peripheral side surface of the partition member and / or a radius on the inner surface of the inner bag constricted portion. You may provide the protrusion part which protruded in the direction inner side. Furthermore, you may provide a metal ring so that it may crimp from the outer side of an inner bag constriction part.

  The engaging portion 162 stops the lower end of the dip tube 28 and has an O-ring 165 on its inner surface, which seals by allowing axial movement between the dip tube and the partition member. . The dip tube used for the partition member 72c has a length from the valve to the partition member. Further, the dip tube is mounted at the engagement portion so as to have a gap between the tip of the dip tube and the upper surface of the main body of the partition member so that the dip tube can move up and down. Therefore, when filling the inner bag using the partition member 72c, force is applied to the inner bag, and the dip tube does not come off even if the inner bag is deformed. Even if the container is dropped during use, an impact is applied to the outer container, and the dip tube does not come off even if the flexible inner bag expands and contracts vertically. Further, even when the engagement between the dip tube and the valve becomes weak, such as when the dip tube deteriorates due to the contents and expands, the dip tube can be supported and prevented from falling into the lower storage portion. Furthermore, when filling the contents, the gas accumulated between the partition wall member and the lower storage portion can be removed by opening the valve.

Further, as in the partition member 72d shown in FIG. 12d, the engaging portion 162 may protrude from the main body 160 as a chimney. Within the engaging portion 162 (in the chimney), the dip tube 28 is slidable. Here, by engaging the dip tube 28 shallowly with the engaging portion 162, the position of the valve can be made higher than the opening of the outer container to facilitate filling of the contents.
Furthermore, the front end of the engaging portion 162 may be brought into direct contact with the lower portion of the valve housing. Thereby, when the valve is fixed, the valve presses the partition member 72d through the engaging portion 162, and the partition member 72d can be prevented from coming off from the constricted portion. Moreover, the same effect can be acquired also in the case of the aerosol container which has the engaging member 74 as shown with an imaginary line. Further, the tip of the engaging portion 162 may be directly inserted into the engaging member 74 without providing the dip tube.

  Here, FIG. 29 shows a manufacturing method of the aerosol product 190b provided with the partition member 72e in which the engaging portion 162 protrudes high from the main body 160 like the partition member of FIG. 12d. First, the contents A are filled into the lower storage portion through the opening of the inner bag 12 inserted into the outer container 11 (FIG. 29a). At this time, the inner bag 12 filled with the content A may be inserted into the outer container 11. Thereafter, the partition member 72e fitted with the dip tube is inserted into the constricted portion 71 of the inner bag, and the upper storage portion 27 is filled with the contents B (FIG. 29b). Here, the lower end (engagement member 74) of the valve 13 is brought into contact with the tip of the dip tube 28, and the valve 13 is placed while the dip tube 28 is pushed down to a state where the pressurizing agent can be filled with the undercup (FIG. 29c). . Further, the air in the space 56 between the outer container 11 and the inner bag 12 is discharged by vacuum or gas replacement. By discharging the remaining air in the space 56 in this way, the reaction between the contents and the remaining air can be prevented, and the stability of the contents can be improved. Thereafter, the space 56 is filled with a pressure agent, and the valve 13 is fixed. In addition, when the gas filling valve | bulb 121 as shown in FIG. 23 is provided in the bottom part of the outer container, you may be filled with a pressurizing agent, after fixing a valve | bulb. Finally, the stem 14 is pushed down, the valve 13 is opened, and the gas 57 mixed in the upper and lower storage portions 27 and 26 when the contents are filled is discharged (FIGS. 29c and 29d). By manufacturing the aerosol product 190b in this way, it is possible to prevent the contents from being ejected vigorously while being mixed with gas during initial use. Moreover, the residual oxygen concentration in the aerosol product can be 1% or less, preferably 0.1% or less, and even when the content reacts with oxygen, the reaction with oxygen is prevented and stable for a long period of time. Can be saved.

  FIG. 30 shows another manufacturing method of the aerosol product 190c provided with the partition member 72f. The aerosol product 190c is provided with a product that can discharge the contents of the upper and lower storage portions without being mixed in the valve 13, as in the valve 13b shown in FIG. 4. Here, the valve 13b shown in FIG. It explains using. In this method of manufacturing the aerosol product 190c, the contents are not filled, the valve 13b is placed, the air in the space 56 between the outer container 11 and the inner bag 12 is discharged, and the space 56 is filled with the pressure agent. Then, the valve 13b is fixed (FIG. 30a). Here, the stem 14 is pushed down, the valve 13 is opened, and the air in the upper and lower storage portions 27 and 26 is discharged (FIG. 30b). Thereafter, one passage 18b of the valve 13b is shut off, and the content A is filled into the lower storage portion 26 from the pond passage 18a of the valve 13b (FIG. 30c). Next, the passage 18a of the valve 13b is shut off, and the content B is filled into the upper storage portion 27 from the passage 18b of the valve 13b (FIG. 30d). The order of filling the contents A and B may be reversed. Manufacturing the aerosol product 190c in this manner is preferable because the contents A and B can be filled without being brought into contact with air. In addition, when the filling valve 121 is provided at the bottom of the outer container as described with reference to FIG. 29, the pressurizing agent is filled after the valve is fixed or after the contents are filled in each storage portion. May be. In addition, when using a valve with a structure that has a space between the mounting cup and the outer peripheral surface of the housing, the stem rubber is bent by the filling pressure to form a gap between the stem rubber and the mounting cup. The upper storage part may be filled with the contents from the outer periphery of the stem through the space from the gap.

  FIG. 31 shows an aerosol product 190d in which the partition member 72f and the valve 13 are connected by a flexible tube 28c. Here, the length of the flexible tube 28c is sufficiently long, and after the valve 13 is fixed as shown in FIG. In the aerosol product 190d, the partition member 72f can be attached to the constricted portion 71 of the inner bag with the upper end of the tube 28c and the valve 13 and the lower end of the tube 28c and the partition member 72f attached, respectively (FIG. 31a). . That is, when mounting the valve, it is not necessary to bring the lower end of the valve into contact with the tip of the dip tube and engage it, so that the valve can be easily mounted. Furthermore, when the upper storage portion is filled with the contents, as shown in FIG. 31a, the tube can be bent and the valve can be shifted from the opening of the inner bag to easily fill the contents.

  The aerosol container 190 in FIG. 13b includes an outer container 11a, an inner bag 12 having a constricted portion 71 at the body, and a bellows 194 that can be vertically expanded and contracted at the neck, and a constricted portion 71 of the inner bag. A partition member 72 having an engagement portion 162 which is mounted and which blocks the lower storage portion 26 and the upper storage portion 27 and whose upper end inner surface is tapered, and a discharge member 190a attached to the valve are further provided. An engaging member 74 for facilitating insertion of the dip tube 28 is provided at the lower portion of the housing, and the other configuration is substantially the same as the aerosol product 75a shown in FIG. 11c.

The outer container 11a is elongated with the same upper end as that of the outer container 11 of FIG. 9a extending upward, with a concave groove protruding radially inward somewhat from the upper end.
The partition member 72 has a through hole 73 inserted so that the dip tube 28 can penetrate the partition member, and after filling, the lower end of the dip tube 28 passes through the through hole 73 and the inside of the lower storage portion 26. (FIG. 13b).

  The engaging member 74 includes a cylindrical portion 197 that is closely fitted to the outer periphery of the dip tube engaging portion at the lower part of the housing, and a tapered portion 198 that has a bottom area extending from the lower end of the cylindrical portion. An insertion portion 193 having a surface is formed. As a result, the tip of the dip tube 28 mounted in advance on the partition wall member abuts on the insertion portion 193 of the engaging member 74 and the dip tube tip is dip simply by installing a valve at the opening of the outer container when manufacturing the aerosol product. It can be guided to the tube engaging portion, and the engagement with the valve 13 is facilitated.

  The discharge member 190a has means for mixing the contents discharged from the valve, and a helix mixer is configured in the discharge member passage. Thereby, the contents mixed in the valve can be mixed uniformly. As such a discharge member, for example, Japanese Utility Model Publication No. 64-25357, Japanese Utility Model Application Publication No. 4-100483, and the like can be used.

  In the method for manufacturing the aerosol product 190, the contents A are filled into the lower storage portion 26 from the opening of the inner bag 12 inserted into the outer container 11a. Next, the partition member 72 into which the dip tube 28 is inserted is fitted into the constricted portion 71, and the content B is filled in the upper storage portion 27. Thereafter, the valve 13 provided with the engaging member 74 is engaged with the dip tube 28, and the space between the outer container and the inner bag is filled with a pressurizing agent such as compressed gas by undercup filling (FIG. 13a). Further, the outer periphery of the lower end of the cover of the valve is clinched so as to push the inner bag 12 into the outer container, and is fixed to the concave groove of the outer container. At this time, the upper end of the inner bag 12 is positioned lower than when filling the contents (FIG. 13b). Since the inner bag 12 has the bellows so that it can expand and contract in the axial direction, the aerosol product 190 can be easily manufactured. In addition, by using a partition member that can penetrate the dip tube, the upper end of the dip tube can be positioned higher than the opening of the inner bag when filling the contents B into the upper storage portion. The contents can be safely filled without intrusion.

The aerosol container 180 of FIG. 14 includes a dip tube 28c that can be expanded and contracted, and the other configuration is substantially the same as the aerosol product 1 shown in FIG.
The dip tube 28c is composed of two tubes 28a and 28b having different diameters, and a thin tube 28b having a small diameter is inserted into a thick tube 28a having a large diameter. Further, the inner diameter of the thick tube 28a and the outer diameter of the thin tube 28b are substantially the same, and the thin tube 28b is formed longer than the thick tube 28a. 13 is the same as the distance between the dip tube engaging portion 55 of the valve and the engaging portion 162 of the partition wall member 72 after being crimped.

  In the manufacturing method of the aerosol product 180, first, the content A is filled in the lower storage portion, and the partition member 72 to which the dip tube 28c is attached is inserted into the constricted portion of the inner bag. The upper end is projected above the opening of the inner bag (see FIG. 14). In this state, the contents B are filled, the valve is placed, and the dip tube 28c is shrunk until the thin tube 28b protrudes from the upper end of the dip tube 28c. The thin dip tube 28b) is engaged (see FIG. 14). Thereafter, the pressurizing agent is filled and the mounting cup is crimped. In this state, both ends of the thin tube 28 b are engaged with the dip tube engaging portion 55 of the valve and the engaging portion 162 of the partition wall member, and both ends of the thick tube 28 a are inside the insertion portion 193 of the engaging member 74. And the inner surface of the upper end of the engaging portion 162 of the partition wall member 72. As a result, the thin tube 28b substantially functions as a dip tube for an aerosol product. The thick tube 28a prevents the contact of the contents B in the upper storage part and the contents A in the thin tube 28b, and further improves the stability of the contents.

  Although the case where the thin tube is longer than the thick tube has been described in the present embodiment, the thick tube may be longer than the thin tube. In this case, when the valve is crimped, both ends of the thick tube are engaged with the dip tube engaging portion 55 of the valve and the engaging portion 162 of the partition wall member, and the thick tube substantially functions as a dip tube for the aerosol product. Play.

  The inner bag 76 shown in FIG. In other words, the first truncated cone 77 closing downward is continuous with the lower end of the cylindrical wall of the upper storage portion 27, and the second truncated cone 78 extending outwardly downward is continuous with the lower end of the cylindrical wall via the valley folding line. Further, a third truncated cone 79 that closes downward at the lower end of the third truncated cone 79 is continuous via a fold line of mountain folds. Similarly, at the upper end of the cylindrical wall of the lower storage portion 26, a bellows half 80b is formed opposite to the half bellows 80a formed by the first, second and third truncated cones 77, 78, 79, One bellows 80 as a whole is continuous with half of the upper bellows. The width of the first truncated cone 77 and the third truncated cone 79 is preferably larger than the width of the second truncated cone 78.

  In the state where the inner bag 76 configured as described above extends in the up-down direction as shown in FIG. 16A, the folding line of the valley fold to which the upper and lower bellows halves 80 a, 80 b are connected, that is, the third truncated cone 79. , 79 is wide in the area of the opening surrounded by the crease line 81 continuous. When the top and bottom are shrunk as shown in FIG. 16b, the crease line 81 is pushed inward, and the area of the opening surrounded by it is reduced. Therefore, the opening / closing action similar to that of the inner bag 12 of FIG. 2 is obtained. A partition member 72 as shown in FIGS. 11a and 11b may be used together. The bellows 80 is not limited to a circular cross section, and may be a rectangular cross section.

  The inner bag 82 shown in FIG. 17A is provided with a cylindrical constricted portion 71 at the central portion 21, and a thin or thick semi-annular fold line 83 is formed at the center thereof. In this embodiment, the crease line 83 is interrupted at two portions 84 facing each other on the front side and the back side. When the inner bag 82 is used, after the first storage portion 26 is filled with the first contents A, the middle of the constricted portion 71 is crushed along the crease line 83 to the left and right as shown in FIG. Thereby, the communication between the upper and lower storage portions 27 and 26 is blocked. At the time of crushing, the portion 84 where the crease line is broken is difficult to bend, and therefore, the portion 84 is crushed along the folding line 83 starting from that portion. As a result, as shown in FIG. 17c, the interrupted portion 84 expands in the lateral direction. This crushed state can be maintained by applying a force in the vertical direction. The dip tube 28 may be inserted before crushing, or may be inserted immediately after crushing or after filling the upper storage portion 27 with the second content B and then piling into the crushed portion. .

  Note that the crease line 83 may be simply provided without providing the constricted portion 71. However, in that case, the portion 84 where the crease line is interrupted protrudes outward as described above (see FIG. 17 c), so that there is a possibility of hitting the inner surface of the outer container 11. Therefore, it is preferable to provide a constricted portion 71 so that the protruding portion is within a predetermined range. Furthermore, the crease line 83 can be omitted in both cases where the constricted portion 71 is provided or not provided. However, it is preferable to provide the crease line 83 because it can be crushed smoothly and the crushed state is stabilized.

  In the case of FIG. 17a, a cylindrical portion is provided in the middle of the constricted portion 71. However, as in the central portion 21 of FIG. 9, the cross-sectional shape viewed from the front or side may be a V-shaped constricted portion. Even in this case, the shape of the crushing becomes clear, and the crushing state is stabilized. In addition, the constricted portion 71 is usually provided uniformly in the circumferential direction, but it may not be provided evenly, for example, by being eccentric to one side. In that case, when a force is applied in the vertical direction, a bending moment acts on the constricted part, and it is in a state of being naturally crushed by the buckling action. Furthermore, the cross-sectional shape seen from the top of the constricted portion 71 may be an ellipse or a rectangle with short left and right dimensions in FIG. 17a and long left and right dimensions in FIG. 17b. Even in that case, it can be crushed smoothly, and the crushed state is stabilized.

  Further, in FIG. 17b, a concave groove may be provided on one wall of the portion to be crushed, and a protrusion that fits into the concave groove may be formed on the other wall, and both may be fitted together. In the case of FIG. 17a, a discontinuous portion 84 is provided in the crease line 83, which is the starting point of crushing. For example, as shown in the inner bag 85 of FIGS. By doing so, it can also be used as the starting point of folding. In addition, it may be folded inward and joined by heat sealing or the like. In either case, the joined portion 86 (a part of the outer wall) at that time becomes a rib in the vertical direction, and the folding direction is determined, so that it can be folded smoothly. Note that an outward rib or an inward rib having an arc cross section may be formed. Further, as shown in FIGS. 18c and 18d, plate-like vertical ribs 87 may be formed integrally with the constricted portion of the inner bag 85, or may be joined after forming. In that case, a hinge 88 serving as a starting point of bending may be formed in the middle of the vertical rib 87.

  In the inner bag 76 of FIG. 16a, the inner bag of FIG. 17a, FIG. 17c, and the inner bag of FIG. 18a, FIG. The parts crushed by means of the pond may be closely bonded to each other by leaving heat sealing, ultrasonic welding, high frequency welding, adhesion with an adhesive, and the like. Thereby, the sealing performance between the storage portions is enhanced. In any of the above embodiments, the number of storage portions is not limited to two, but may be three or four or more. Moreover, the material of these inner bags is substantially the same as the inner bag 12 of FIG. Therefore, the inner bag has an excellent barrier function, and durability is high even when the contents made of the acidic stock solution and the alkaline stock solution are used.

  The inner bag 85 shown in FIG. 19a is divided into an upper storage member 85b and a lower storage member 85a. The upper storage member 85b has a cylindrical shape, and has a body part 89a, a shoulder part 89b extending in a tapered shape from both upper and lower ends of the body part 89a, and a neck part 89c extending from these end parts. A flange portion 89d is formed, and a female screw 98a is formed inside the lower neck portion. The lower storage member 85a has a bottomed cylindrical shape, a body part 89a, a shoulder part 89b that extends in a tapered shape from the upper end of the body part, and a neck part 89c that extends upward from the upper part of the shoulder part and has a smaller diameter than the body part. A male screw 98b is formed on the outer surface of the neck. A female screw 98a at the lower neck portion of the upper storage member 85b and a screw 98b at the neck portion of the lower storage member 85a can be connected to each other, and substantially one inner bag 85 is formed by screwing them together. To do. Thereby, the connection part of this inner bag 85 corresponds to a constriction part. Further, when the inner bag 85 is used in the packaging container of the present invention, the partition member can be used as a partition, but aluminum is formed on the surface where these upper and lower storage members are in contact or the lower shoulder opening of the upper storage member. Sealing is performed using a thin film (not shown) such as a foil or a synthetic resin film. Alternatively, the upper storage member 85b may be formed into a bottomed cylindrical shape. Next, each storage unit is filled with contents, the upper and lower storage members are connected to each other, and after being stored in the outer container, the films are broken by the dip tube 28 when the valve is placed on the outer container. The packaging container of the present invention can be obtained. Here, a screw is used as the connecting means, but the present invention is not limited to this, and the diameters of the upper and lower openings may be different so as to be fitted. Furthermore, it is good also as fitting of taper surfaces. Further, it is preferable that the dip tube 28 has a sharp tip so that the film or the like is easily broken. Further, the upper and lower storage portions may be sealed using a dip tube 28 having substantially the same outer diameter as the inner diameter of the connecting portion without using a film. The upper and lower storage members 85a and 85b of the inner bag are formed from the same material as the inner bag 12 of FIG. Moreover, since the thin film used between the upper and lower storage members is also formed of the same material as the inner bag, the barrier function is high and the durability is high even when the contents of the acidic stock solution and the alkaline stock solution are used.

  An inner bag 85d shown in FIG. 19b is an inner bag made of metal such as aluminum. The inner bag 85a is composed of upper and lower storage members 85a and 85b, similar to the inner bag 85 of FIG. 19a. This upper and lower storage member is formed by laminating a sheet of aluminum or an aluminum inner surface and / or outer surface laminated with a resin sheet such as the above-mentioned alkali-resistant layer or acid-resistant layer, and the upper storage member 85a is a cylindrical upper member. A cylindrical lower neck portion 86b having a neck portion 86a and a female screw is sandwiched between two aluminum sheets and the edges are bonded together. The lower storage member 85b is formed by sandwiching a cylindrical neck portion 86d having a male screw with an aluminum sheet. The inner bag 85d is generated by screwing the lower neck portion 86b of the upper storage member 85a and the neck portion 86d of the lower storage member 85b.

  As a method of filling the packaged product of the present invention using this inner bag, a thin film is applied to the inner surface of the tapered lower shoulder 89b of the upper storage member 85b to form the bottom, and the upper and lower storage members are separately provided. Fill the contents with a line, connect them and insert them into the outer container. Next, a valve with a dip tube is attached to the upper neck portion of the upper housing member, the film is broken, the pressure agent is filled, and the valve is fixed. Alternatively, the lower storage member 85a is filled with contents, covered with a film, the upper storage member 85b is connected, the upper storage member is filled with the contents, and then the filled inner bag is accommodated in the outer container, and the valve is You may make it insert and fill with a pressurizing agent. This can increase the production speed of the product. Furthermore, since the inner bag of the material corresponding to the contents can be used, the contents can be stably stored for a long period of time.

In addition, when sealing the upper and lower storage parts with a dip tube having substantially the same outer diameter as the inner diameter of the connecting part without using a film, the lower storage member is filled with the contents, and the upper storage member is connected. A tube may be inserted, the upper storage member may be filled with the contents, and the pressurizing agent may be filled. In this case, after the upper and lower storage members are connected, the contents are placed in the order of the lower storage member and the upper storage member. It may be filled.
Furthermore, you may use the dip tube which has an outer diameter substantially the same as an internal diameter of a connection part using a film. Thereby, a sealing performance can be improved further.

  The inner bag 185 of FIG. 20 has a constricted portion 71 that divides the storage portion in the upper and lower portions in the vicinity of the center. The inner diameter of the storage part 26 is smaller than the diameter of the opening part of the outer container 11. In this method of filling a packaged product using the inner bag 185, the contents A of the lower storage portion 26 are first filled, and the shoulder portion 186 composed of the upper storage portion 27 and the constricted portion 71 is indicated by an imaginary line. The lower storage portion 26 of the inner bag 185 is inserted into the outer container 11 so as to be hooked on the opening portion of the outer bag 11. Next, the partition member 72 with the dip tube 28 inserted is inserted into the constricted portion 71, vacuumed from the opening of the inner bag 185, the upper storage portion 27 is contracted, and the inner bag 185 is inserted into the outer container 11. Thereafter, the contents B, the pressurizing agent and the like are filled by a conventional method. By this filling method, the oxygen concentration in the inner bag can be lowered and the contents are less likely to come into contact with oxygen after filling, so the contents can be stored in a stable state, and packaging products (aerosol products) Can be stored stably for a long time. The other structure is substantially the same as the inner bag 12 of FIG.

  The inner bag 187 shown in FIG. 21 is formed with a narrow portion 71 near the center for dividing the inner bag into upper and lower storage portions 27 and 26. The diameter of the narrow portion 71 is a dip tube. The outer diameter of 28 is substantially the same. Thus, when the dip tube 28 is inserted, the upper and lower storage portions 27 and 26 are sealed except for the passage of the dip tube 28. The narrow constricted portion can prevent contact between the contents A and the content B, and desired stability can be obtained by adjusting the narrowness and length of the constricted portion. In this method of filling a packaged product using the inner bag 187, the content A is first filled in the lower storage portion 26, the dip tube 28 is inserted into the constricted portion 71, and the content B is filled in the upper storage portion 27. Further, a lip may be provided on the constricted portion 71 in order to ensure sealing performance.

The aerosol container 90 of FIG. 22 has an inner bag having a rigid or translucent synthetic resin or pressure-resistant glass outer container 91 and upper and lower storage portions 92a and 92b that are housed in the outer container 91. 92 and a valve 93 attached to the opening of the outer container.
The outer container 91 has a cylindrical body with a bottom, a shoulder extending in a tapered shape from the upper end of the body, and a neck formed continuously from the shoulder. A concave groove 91a is formed at the lower end of the neck portion continuously from the upper end of the shoulder portion. This outer container 91 can be manufactured by a conventionally known blow molding or the like in which a parison made of a synthetic resin such as polyethylene terephthalate or polybutylene terephthalate is inflated with air pressure, closely attached to a mold, and cooled to obtain a hollow body. it can. In addition, you may use the outer container of the shape currently disclosed by Unexamined-Japanese-Patent No. 2000-327053. Thus, by making the outer container 91 transparent or translucent, the contents can be confirmed from the outside, and the internal capacity (remaining amount) or the state of the upper and lower storage portions can be confirmed. In particular, in the case of an aerosol product filled with contents that react by mixing with each other in the upper and lower storage parts, the accurate remaining amount of the contents can be confirmed by providing a scale on the outer container, This is preferable because the state can be confirmed. In this embodiment, since the outer container is transparent or translucent, the remaining amount of contents can be confirmed by appearance. On the other hand, when the outer container is transparent below, it is preferable to connect a thread or string in the middle of the product in the vertical direction. In this case, the remaining amount of the contents can be confirmed by tilting the product by picking the other end of the thread and hanging the product.

  The inner bag 92 is substantially the same as the inner bag 187 of FIG. 21 described above, and is provided with a constricted portion 94 smaller than the opening of the outer container 91, and the constricted portion 94 inserts a dip tube. Thus, the upper and lower storage portions can be partitioned. However, the gas absorbent 95 disclosed in Japanese Patent Laid-Open No. 9-104487 is molded into a sheet shape on the outer peripheral surface of the constricted portion 94 between the upper storage portion 92a and the lower storage portion 92b of the inner bag. A thing stored in a gas-permeable bag is provided. In the case of such a gas absorbent 95, the contents filled in the storage portion are a hair dye first agent containing a stabilizer such as ammonia or a hair dye second agent containing an oxidizing agent such as hydrogen peroxide. Is particularly preferred. Thereby, even when the ammonia gas generated from the oxygen and ammonia generated by the decomposition of hydrogen peroxide passes through the inner bag 92 and comes into the space between the inner bag and the outer container 91, Since oxygen and ammonia gas are absorbed, it is possible to prevent the pressure inside the outer container from rising. Further, it is possible to prevent the deterioration of the contents due to the generated gas and the corrosion of the outer container. The gas absorbent 95 may be coated on the inner side of the inner bag 92. In this case, the gas accumulated in the inner bag without passing through the inner bag can be absorbed. However, in the case of the inner side, it is in direct contact with the contents, and since the surface of the gas absorbent is covered with liquid, the contact with the generated gas is reduced and the gas absorption action is hindered. It is effective. Further, this gas absorbent may be provided on the shoulder portion or the outer peripheral surface of one storage portion. Further, it may be provided on the entire outer surface of the inner bag 92 or on the inner surface of the outer container 91. Further, a gas absorbent in a gas permeable bag may be stored in the outer container. Moreover, you may use a gas absorption sheet for the intermediate | middle layer of the inner bag currently described in Japanese Utility Model Publication No. 5-34780. Further, a safety valve or a mechanism that discharges gas to the outside when the internal pressure of the outer container 91 is a certain pressure or more may be provided. As such a mechanism, the lid member mounting structure disclosed in JP-A-8-104381 or the shape of the outer container mouth or mounting cup disclosed in JP-A-7-149382 may be used. . In this case, an amount of gas exceeding the amount absorbed by the gas absorbent is generated, the gas absorbent does not absorb the specified amount, or the pressure in the outer container 91 rises abnormally, causing the valve or the like to escape. This can be prevented. Further, as described above, the inner bag may be provided with a check valve disclosed in Japanese Patent Laid-Open No. 8-133359 that allows the gas accumulated without passing through the inner bag to communicate from the inside to the outside. . Thereby, the inner bag can be prevented from expanding, and further, the inner bag can be prevented from rupturing due to the expansion.

  The valve 93 fixes the housing in such a manner that a cylindrical housing having a protruding portion protruding radially outward at the upper end and the opening of the outer container 91 is sandwiched between the protruding portion and the opening of the outer container. And a mounting cup that seals the outer container by caulking the groove 91a. The other configuration is substantially the same as the valve 13 of FIG. The inside of the housing and the upper storage portion 92a communicate with each other through a communication hole 97a formed in the side wall of the housing, and the lower storage portion communicates with the dip tube 28 through a communication hole 97b at the lower end of the housing. The diameter of the dip tube 28 is slightly larger than the small constricted portion 94 of the inner bag 92. Therefore, the upper and lower storage portions of the inner bag can be blocked by inserting the dip tube 28 into the constricted portion 94 of the inner bag. Although the length of the dip tube 28 is not particularly limited, it is preferable that the dip tube 28 reaches the bottom of the aerosol container 90 so that a passage is secured even if the inner bag 92 is crushed as the contents are reduced. Further, the strength of the constricted portion 94 of the inner bag may be made stronger than the other portions, and the length of the dip tube 28 may be such that the lower end is positioned in the vicinity of the constricted portion. In this case, it is preferable that the inner bag 92 is configured to contract in the order from the bottom to the constricted portion as the contents of the lower storage portion 92b decrease. Also in this embodiment, a lip seal similar to the lip seal 71a shown in FIG. Thereby, an upper and lower storage part can be closed more firmly. The other structure is the same as that of the aerosol container 75a of FIG. 11c, and the same action can be obtained.

  In the embodiment of the packaging container disclosed so far, a space 96 is provided between the upper storage portion and the lower storage portion, as shown in FIG. . That is, depending on the contents, there are those that easily penetrate the synthetic resin sheet constituting the inner bag, and when the partition partitioning the contents is only the synthetic resin sheet, the contents permeate the partition and other contents May react and deteriorate. However, in the above-described packaging container, even if the contents permeate the sheet constituting the inner bag, the space 96 cannot directly contact the inner bag filled with the other contents. It is possible to prevent permeation through the inner bag filled with the object. Furthermore, when used in combination with the gas absorbent described above, the effect of preventing penetration is further enhanced. Moreover, it is preferable to use a partition with high gas barrier property also about a partition.

  The aerosol container 120 of FIG. 23 is hung by sandwiching a valve with a filling valve 121 that fills the bottom of the outer container with a pressurizing agent, and the opening of the container body so that the lower end does not contact the bottom of the container body And an inner bag 122 provided (Japanese Patent Laid-Open No. 2000-24557). The inner bag 122 is divided into upper and lower storage portions by a constricted portion 71 at the center, and the constricted portion 71 is provided with the same material as the partition wall member 72 of FIG. Furthermore, the inner bag 122 is provided with a fold line 123 in the axial direction, and is configured to bend and shrink along the fold line as the contents are discharged. In the aerosol container 120, the upper and lower storage portions of the inner bag 122 are filled with each content, and the valve 124 is fixed. Thereafter, an aerosol product can be obtained by filling the pressurizing agent from the filling valve 121. In this embodiment, the upper end opening of the container body is bent inward to fix the valve (Japanese Patent Laid-Open No. 2000-62870).

  The aerosol container 130 of FIG. 24 includes a bottom part 132, a body part 133, and a head part 134, and is suspended from an opening of the container body 131, which is a three-piece can formed by double tightening them. And an inner bag 135 configured as described above. The inner bag 135 has a constricted portion 71 in the center, and a partition member 72 into which the dip tube 28 is fitted is provided in the constricted portion. Further, a cylindrical degasser 136 having a plurality of sharp blades radially outward is provided on the partition wall member 72. The degassing tool 136 is joined by being fitted together with the dip tube 28 in the central portion of the partition wall member 72. When almost the entire contents are discharged by the degassing tool 136, the inner bag 135 is broken by contraction, and the inner space of the outer container and the inner space of the inner bag are communicated. After discharging the whole amount, the pressure agent in the inner space of the outer container can be discharged naturally by opening the valve. After use, there is no need to take special measures such as opening a hole in the outer container and venting the gas, it is safe to use an aerosol container, and it is also preferable for recycling. The gas vent 136 may be formed integrally with the partition wall member 72 using a synthetic resin or the like. Further, in the aerosol product of the present invention, as such a gas venting tool, a gas venting jig shown in FIGS. 1 and 5 of JP-A-9-267876, FIG. 1 of JP-A-10-310111, 3, 4, 5, 6, 7 and 8 are shown in FIGS. 1, 3, 4, 6, 7, 8, 9, 10, 11 and 12 of JP-A-11-171268. The degassing tool shown may be used.

  In the embodiments described so far, the aerosol container in which the internal pressure of the container is increased by a pressurizing agent such as a compressed gas has been disclosed. However, the packaging container 100 in FIG. Yes. The valve 101a including the pump mechanism 101 includes a housing 102, a stem 103 accommodated in the housing, a spring 104a that constantly biases the stem upward, and a check valve function accommodated in the housing. The piston 104 is configured to include a communication hole 103a, 103b provided at the lower end of the housing 102, and check valves 106a, 106b that close the communication hole 103a, 103b. These check valves 106a and 106b are the same as the check valve 51a shown in FIG. 3a, and are configured such that the communication holes 103a and 103b are closed by a ball urged toward the communication holes 103a and 103b by a spring. ing. The stem 103 and the piston 104 are conventionally known, and a push button is attached to the upper end of the stem 103. Further, a dip tube 28 is attached to the communication hole 103a, thereby communicating with the lower storage portion. Other configurations of the inner bag and the outer container are the same as in FIG. 2 or FIG. Accordingly, when the push button is pushed down, the piston 104 is lowered, and the contents of one time are discharged into the housing 102 by the action of the check valve. Thereafter, the push button is lifted by the spring 104 through the stem 103. During this ascent, the first and second pistons (not shown) are also raised, and the contents for the next discharge are sucked into the housing 102 through the check valves 106a and 106b at the lower ends. By using a packaging container having such a pump mechanism, two different contents can be used without leaving them in the inner bag. Other configurations In particular, the configuration of the inner bag is substantially the same as that of the inner bag 12 of FIG.

  FIG. 26 shows an embodiment of a squeeze bottle type packaging container that directly extrudes contents by external force. The packaging container 110 is composed of a flexible outer container 111, an inner bag 112 having storage portions on the upper and lower sides, and a cap 113 attached to the opening of the outer container. In this packaging container 110, the outer container 111 constitutes a pump, and is configured to elastically return to its original shape even when deformed by receiving a force locally. A hole 115 communicating with the outside air is formed in a part of the outer container 110, and a check valve 114 is provided inside the hole 115.

  The inner bag 112 is the same as that of the aerosol container 90 of FIG. 22, and is divided into upper and lower storage parts. The cap 113 is substantially chevron-shaped and made of synthetic resin, and has communication holes 115a and 115b at the bottom. The central communication hole 115b communicates with the lower storage part via the dip tube 28, and the other communication hole 115a communicates directly with the upper storage part. The upper portions of these communication holes 115 a and 115 b are connected to the spout 117 via the housing mixing chamber 116. As a result, when the cap 113 is fixed to the outer container and an external force Q is applied so as to crush a part of the outer container 111, a uniform pressure is applied to the entire inner bag 112, and the upper and lower storage portions pass through the communication holes 115a and 115b, respectively. Then, after mixing in the housing mixing chamber 116, the mixture is mixed and then discharged through the spout 117. A check valve 118 is provided on the top surface of the housing mixing chamber 116 so as not to suck air from the spout 117. Further, it is preferable to provide check valves in the communication holes 115a and 115b which are the inlets of the housing mixing chamber 116. In this case, the contents mixed in the housing mixing chamber 116 can be prevented from flowing back into the dip tube 28. The length of the dip tube 28 may be up to the constricted portion 94 and may extend to the lower end.

  FIG. 27 shows an embodiment of a packaging container 140 that pushes out contents by the elastic force of the inner bag itself. The packaging container 140 includes a valve 141, an inner bag 142 made of an elastic material such as synthetic rubber or silicone rubber, a container body that houses the inner bag 142 and engages the valve 141 at an opening, and fixes them. It consists of a cap. Moreover, the inner layer of this inner bag is laminated with an alkali-resistant layer or an acid-resistant layer to prevent erosion of the inner bag by the contents. Moreover, you may manufacture using materials with high alkali resistance and acid resistance, such as fluororubber. The inner bag 142 is configured so that the inner surfaces are in close contact with each other in a natural state, leaving no space in the inner bag (elastic energy is zero). The inner bag is then inflated by filling the contents (elastic energy is stored). Therefore, by opening the valve, almost the entire contents can be discharged. The valve is firmly inserted into the inner bag opening and encloses the contents. The valve 141 is a conventionally known one. The packaging container 140 may not have an outer container as long as the space between the valve and the inner bag is tightly sealed. In this case, the inner bag serves as the outer container and the pressurizing means. In that case, the opening of the inner bag 142 may be further tightened with a metal wire or the like. Further, a rubber belt or the like having elasticity may be wound around the upper and lower storage portions of the flexible inner bag.

The aerosol container 170 of FIG. 28 has a valve 171, an inner inner bag 172 whose upper end is connected to the valve, and an outer inner bag 173 that accommodates the inner bag. Here, the outer inner bag 173 corresponds to the inner bag of the present invention, and the inner inner bag 172 corresponds to a partition wall that partitions the outer inner bag 173. However, the above-described partition member does not transmit pressure between the upper and lower storage portions, but the inner bag 172 transmits pressure between the upper and lower storage portions. The valve uses the valve 13b, 13c, or 13d shown in FIGS. 3 to 6, and these valves have a communication hole 48a at the lower end of the valve and a communication hole 48b on the upper side surface of the valve. The inner inner bag 172 is attached so as to cover the valve housing and not to block the communication hole 48b, and communicates with the valve through the communication hole 48a. The outer inner bag 173 communicates with the valve through the communication hole 48b. As a result, the contents of the inner and outer inner bags flow into the valve by opening the valve. In order to further strengthen the seal between the inner inner bag 172 and the valve, a sealing mechanism such as an O-ring may be provided between the inner inner bag 172 and the valve. In the method for producing an aerosol product using this aerosol container, the contents are filled with the inner and inner bags 172 and 173 stored in the outer container on separate lines, and the inner and inner bags 172 are fixed to the valve. Next, the valve is inserted into the outer inner bag 173. Here, it can be manufactured by filling the pressure agent and fixing the valve. Further, the inner bag may be fixed to the valve in advance, and the contents may be filled from the valve.
As described above, when the outer container is opaque, it is preferable to include a remaining amount confirmation unit that can confirm the remaining amount of the contents of the product.

  FIG. 32a shows an example of an injection member that can be used in the aerosol product of the present invention. The injection member 200 is used for an aerosol product that can discharge the contents of the upper and lower storage portions without being mixed in the valve 13 like the valve 13b shown in FIG. The injection member 200 has a cylindrical shape, a stem engaging portion 201 that engages with the stem 14, a nozzle 202 that simultaneously injects the contents A and B supplied from the stem, and the respective contents A and B. The injection member passages 203a and 203b flow between the stem engaging portion and the nozzle 202.

The nozzle 202 has a bottomed cylindrical shape, is provided with an injection hole 202a at the center of the bottom, and engages with the injection member main body 204. The nozzle 202 has a spiral projection 208 formed on the bottom inner surface 206 which is a contact surface with the ejection member main body 204 from the side edge portion toward the center. In addition, between the projections and on the side edge of the bottom inner surface 206, the openings 209a and 209b of the injection member passages 203a and 203b are located (see FIG. 32b).
As a result, the contents A and B discharged from the valve passages 18a and 18b respectively pass through the injection member passages 203a and 203b and reach the bottom inner surface 206. At the bottom inner surface 206, the contents A and B form a vortex flow by the projection 208, both contents are mixed, and the mixed contents are injected from the injection hole 202.

  Such an injection member 200 has a low viscosity, is liquid, is sprayed in the form of a mist or mist, reacts when two liquids come into contact with each other, or mixes when using a content that exhibits an effect. It is large and the effect can be obtained simultaneously with the injection, which is preferable. For example, in the case of using a content that is neutralized and thickened by mixing, it starts to thicken at the injection hole, becomes a coarse mist, becomes a gel on the adhesion surface, and does not sag. In addition, when using a content that dissolves by mixing and generates heat or absorbs heat, it is sprayed into a warm or cold mist or mist.

FIG. 33 shows another example of an injection member that can be used in the aerosol product of the present invention. This is also used for aerosol products in which the contents A and B can be discharged without being mixed in the valve as in FIG. The injection member 211 includes two nozzles 205a and 205b having two injection holes 202a and 202b and an injection member main body 204. The injection angles of the two injection holes 202a and 202b intersect each other. Is provided. When the injection member is used for injection, the injection material injected from each injection hole is mixed at a distance not far from the injection hole. Therefore, when using a two-component reaction type content that starts to react immediately after mixing, it starts to react in space or immediately after adhering to the object, and the effect can be obtained in a short time after injection.
Here, the nozzles 205a and 205b are engaged with the injection member main body 204, but may be integrally formed.

  FIG. 34 shows still another example of the ejection member. This injection member 215 separately injects the separately supplied contents, like the injection member 211 of FIG. The injection member 215 is inserted into the injection member main body 204 through which the contents A and B separately supplied from the valves are passed through the injection member passages 203a and 203b and the nozzle insertion port 216 of the injection member main body. Nozzle 202. The injection member 215 has a central injection hole 202a and three outer injection holes 202b formed at a uniform interval on the outer periphery of the central injection hole 202a. The central injection hole 202a has a circular shape, is provided at the center of the nozzle, and communicates with the injection member passage 203a. Further, a groove 217 is formed in the inner surface axial direction of the nozzle insertion port 216, and this groove 217 communicates with the injection member passage 203b. A slit between the groove 217 and the nozzle 202 is an outer injection hole 202b. Is forming. The number of the outer injection holes 202b is not limited, and about 2 to 10 can be provided. Since it is formed in this way, the sprayed material sprayed from the spraying member 215 has a stripe shape. As a content of the aerosol product used for such an injection member 215, a thing with high viscosity is preferable. As a result, the sprays sprayed in stripes can be easily mixed by applying another force such as a hand. In addition, as the contents A and B, a gel-like content and a mousse-like content are used, respectively, and the gel-like content passes through the ejection member passage 203a and is ejected from the ejection hole 202a. By connecting the packaging container of the present invention and the spray member 215 so that the spray material passes through the spray member passage 203b and is sprayed from the spray hole 202b, the gel-like contents are wrapped in the mousse-like contents. Obtainable.

Here, in the packaging container of the present invention, a preferred form of the inner bag filled with two kinds of contents is shown in FIG.
The inner bag 220 has a bottomed cylindrical shape, and includes a body portion 224 having an upper storage portion 221, a lower storage portion 222, and a constricted portion 223 interposed between the upper and lower storage portions, and an upper end of the body portion. The neck 225 is formed and provided with a flange 225a at the upper end, and the bottom 226 closes the lower end of the trunk.

  The inner bag 220 is formed by molding a tube-shaped synthetic resin using the same material as the inner bag 12 of FIG. 1, and is formed by blow molding, and the bottom portion 226 is formed by bonding the synthetic resin. Therefore, an inner bag can be manufactured continuously and production efficiency is good. However, if the contents generate or contain gas, the gas may permeate from the bottom joint surface. In order to prevent the permeation of the gas, a resin sheet may be attached under the bottom 226 or a gas absorption coat 227 made of a gas absorbent may be provided. Thereby, the permeation of the gas can be further prevented and the barrier function can be enhanced. Particularly, when the gas is an alkaline gas such as ammonia or an oxidizing gas such as oxygen gas, the outer container made of the gas Can prevent corrosion. Further, as indicated by an imaginary line, a cylindrical gas absorption bag 228 that is housed in the outer container, is attached between the outer container and the valve, and houses the entire inner bag 220 may be provided.

In such an inner bag, since a plurality of different contents are filled, the inner bag needs to be stable with respect to each content. Here, the term “stable” means that the inner bag has corrosion resistance with respect to the contents, or the contents prevent permeation of gas generated by self-decomposition or the like, and are not easily deteriorated as a packaged product.
Examples of such inner bags include those formed by laminating materials that are stable with respect to the contents filled in the respective storage units. In addition, the inner bag formed of a material that is stable with respect to the contents to be filled in any of the storage parts is provided with a material that is stable with respect to the contents to be filled in the other storage parts. The peripheral surface may be covered with a film or the like. Furthermore, as shown in the inner bag 85 of FIG. 19a, the upper storage member 85a and the lower storage member 85b are formed, and the upper and lower storage members 85a and 85b may be formed of a material that is stable with respect to the filled contents. Good. By configuring the inner bag in this way, the aqueous storage solution having a pH of 11 to 13 is filled in either the upper or lower storage portion of the inner bag and the remaining storage portion is filled with water at 25 ° C. Even when a highly reactive content consisting of an alkaline stock solution and an acidic stock solution has an excellent barrier function in which the pH change of water after a lapse of months is less than 3, it can be stably stored for a long period of time.

  Furthermore, as shown in FIG. 36 a as an inner bag used for a packaged product in which an upper bag is filled with an alkaline content and an acid content is filled in a lower housing portion, in an inner bag having upper and lower housing portions, An inner bag 230 having a two-layer structure can be used. The inner bag 230 is composed of an inner layer (alkali resistant layer) 231 made of a material excellent in alkali resistance and an outer layer (acid resistant layer) 232 made of a material excellent in acid resistance laminated on the outer side of the inner layer. Yes. The material of the inner layer and the outer layer may be reversed. This prevents the inner bag from being corroded and ruptured by the contents. Moreover, an alkaline component or an acidic component does not permeate the inner bag and corrode the outer container, and does not permeate into the other storage portion to deteriorate other contents.

  Moreover, the inner bag 234 of FIG. 36b may be used, and the inner bag 234 is made of the material having excellent alkali resistance (acid resistance) to the inner bag body 235 made of the material having excellent acid resistance (alkali resistance). The film 236 is laminated on the outer peripheral surface of the upper storage portion 221. The film 226 is laminated on the lower storage portion 26 when the alkaline content is filled in the lower storage portion 222. As a means for laminating on the outer peripheral surface, it may be laminated at the time of inner bag molding, or may be pasted or heat-shrinked (shrinked) after inner bag molding.

  Since the inner bag used in the packaging product of the present invention has an excellent gas barrier function, it is composed of an alkaline stock solution containing a volatile alkali component such as ammonia and an acidic stock solution containing an oxygen generating component such as hydrogen peroxide. Even with highly reactive contents, the ammonia concentration in the alkaline stock solution is reduced by permeation of ammonia and oxygen from the inside of the inner bag to the outside and from the outside to the inside over time, and peroxidation in the acidic stock solution Hydrogen decomposition can be prevented, reaction components such as oxidation dyes blended with ammonia and stabilized by ammonia, and further hydrogen peroxide decomposition can be prevented, and a stable hair dyeing effect can be obtained.

  The packaged product thus obtained has an excellent barrier function, so it has not only highly reactive contents such as a two-component reactive hair dye, a decolorizer, and an enzyme hair dye, but also a hair setting agent, a hair restorer. It can be an aerosol product that is discharged as an anti-inflammatory analgesic, anti-hot flash, cooling agent, pack agent, cleansing agent, shaving foam, moisturizer, antiperspirant, vitamin agent, emollient and the like.

The lower storage part of the inner bag having the same shape as the inner bag shown in FIG. 1 was filled with 5% ammonia aqueous solution (pH 12.1), and a partition member (made of stainless steel) was inserted to block the lower storage part. Subsequently, the upper storage part was filled with purified water (pH 6.2), and a valve mounting cap was inserted into the opening of the inner bag to seal it, and the upper storage part was shut off. Further, nitrogen gas was filled as a pressurizing agent between the inner bag and the outer container (product pressure at 25 ° C., 0.8 MPa), and a valve was fixed to the opening of the outer container.
Table 1 shows the laminated structure of the inner bag and the material of those layers used in Examples or Comparative Examples of the double aerosol of the present invention.

※カッコ内の数値は層の厚さ（μｍ）

* Figures in parentheses are layer thickness (μm)

  Each obtained aerosol product was stored at 25 ° C. for 1 month, and the stored nitrogen gas was discharged to collect only purified water in the upper storage section. The collected purified water was adjusted to 20 ° C. and the pH was measured. The results are shown in Table 2.
