Therefore, the flow velocity of two contents in the unified path will be same. Resultantly the discharging amount of two contents can be controlled.
In the case where the activating part has a translucency, the discharging rate of the contents can be visually seen by the width of each contents flowing in the unified path. Therefore, if the boundary line is formed on the middle of the unified path, the discharging rate of two contents are same. Further, discharging rate of two contents can be noticed accurately by providing scale marks in the width direction of the unified path.
On the other hand, in the case where the activating parts are attached to each of the stem of the aerosol valve, the independency of contents can be secured until it is discharged.
In the case that the outer container of the aerosol container of the present invention is made of synthetic resin, the remaining of the contents in the content storage part can be visually noticed.

Therefore, even content having high reactant ingredient is stored for a long period of time, the component penetrated the second inner container will not reach the first inner container. Specifically, the component which generates the gas by decomposition such as hydrogen peroxide, is charged in the second inner container, the gas formed in the second inner container is ejected outside by penetrating. Therefore, it can prevent the gas pile in the second inner container. As a result it prevents the spattering of the content when discharging, and prevents the bursting of the second inner container due to the rise of the inner pressure at the time of storage. Further, it can have the second inner container to shrink when discharging the contents.
In the case where the outer container and the second inner container have translucency, the condition of the inner container and the remaining of the contents can be confirmed visually.

Specifically, in the case, where the pouch has an inner window portion having translucency which can be seen from the outer window portion, and contents which are to be charged in the pouch is an opaque, and it is structured so that the sign can be seen from the inner window portion, when the contents are discharged and the volume of the pouch is reduced, user can notice the remaining of the content by looking the inner window portion.
In the case of aerosol container of present invention, where the content storage part is an inner container, and the inner container has a barrel portion in which the content is charged, and a leg portion integrally formed on a lower end of the barrel portion, and where when the inner containers are connected to the aerosol valves and laid on a bottom surface of the outer container, a position of the valve assembly is higher than the position of the valve assembly to be fixed to the outer container, supported by the leg portion of the inner container, and the leg portion is bent when the valve assembly is fixed to the outer container, the inner container can be inserted into the outer container without having the barrel portion deforms. Therefore, when the content is charged in from the valve, the inner container expands as predetermined shape, and prevents the burst of the inner container due to the pressuring of the limited area.
In the case that the inner container is a pouch formed by bonding two flexible sheet, and the leg portion is a lower end bonded part in which a lower end of the sheets are bonded, the structure of the inner container is simple.
In the present invention of the aerosol product, because it is equipped with an aerosol container of present invention having two content storage part, a propellant charged into the propellant storage part, and two contents charged into the content storage part respectively, and where the two contents are a two liquid type reaction ingredients, the content can be stably stored for long period of time.

Because the valve assembly 13 has two independent and separate aerosol valve, each content passing each aerosol valve can be discharged outside maintaining the independent condition. In other word, because the inside (housing 26) of each aerosol valve 15 is independently sealed, the material of the aerosol valve can be selected according to the content. Therefore, not only the degradation due to the direct contact of the content in the valve assembly can be prevented, the degradation due to the penetration of the content can also be prevented.
The aerosol container 10 can be manufactured by, for example, placing the sealing member 23 and the valve holder 21 on the outer container 11, and hooking the flange portion 12d of the inner bag 12 to the lower tubular portion 37b of the valve holder 21, like shown in imaginary line of
The aerosol product simultaneously discharging different content may be produced by charging different kind of the content in the inner bag 12 of the aerosol container 10. When the content is two liquid type reaction ingredients, the reaction effect of the contents can be obtained by simultaneously discharging the contents, and mixing it afterward. For such a two liquid type reaction ingredients, two liquid type hair dyes, two liquid type permanent wave agents, two liquid type adhesive agents may be cited. Particularly, when it is two liquid type hair dyes, because the discharged object is used for the hair which the user can not see directly, the discharging both content in one container will ease the hair dye procedure.
Moreover, the propellant is charged in space between the space (propellant storage part) of the outer container 11 and the inner bag 12, the propellant may be charged together with aqueous solution such as water. Specifically in the two liquid type hair dye, it is known that the high permeability ingredient (ammonia) is included in the content, however the charging of the aqueous solution in the space between the outer container 11 and the inner bag 12 can trap the high permeability ingredient in the space by dissolving in the aqueous solution. Therefore, it can prevent the mixture of two contents due to the penetration.

The gas barrier property of the intermediate layer 278b is that under pressure of 0.2 to 1.0 MPa, it prevents the penetration of the water property of moisture or humidity and allows the gradual penetration of the gas such as oxygen and ammonia. The gradual penetration of the gas is to have oxygen permeation rate of 0.7 to 100 (cm3/m2/24 h/atm).
The combination of the outer layer 278a, the intermediate layer 278b, and the inner layer 286c of the second inner container 274 can be selected according to the ingredient of the content. For example, when the second agent of the two liquid type hair dye having acid property including the oxidant such as hydrogen peroxide and etc. is used as the second content A2, the combination of PE/EVOH/PE, PP/EVOH/PE, PET/EVOH/PE, PE/EVOH/PET, PE/NY/PE, PP/NY/PE, PET/NY/PE, PO/SiO2/PE, PP/SiO2/PE, PET/SiO2/PE, PE/Al2O3/PE in order of outer layer 278a/intermediate layer 278b/inner layer 278c can be cited. Specifically, it is preferable to use synthetic resin layer as intermediate layer. Further, the bag body 278 of the second container may have two layer structure omitting the outer layer 278a, and may have four or more layer structure using synthetic resin or a metallic foil arbitrarily. Moreover, it is preferable to have the second inner container with transparent property when the outer container 271 is made with transparent property.
The product is manufactured by charging the first content A1 into the first inner container 273, charging the second content A2 into the second inner container 274, and charging the propellant into the space S formed between the outer container 271, and the first inner container 273 and the second inner container 274. Therefore, by operating (lowering) the discharging member attached to two stems 27 of the aerosol valve 15 of the valve assembly 276, the first inner container 273 and the atmosphere, and the second inner container 274 and the atmosphere communicates with each other. Then the pressure of the propellant presses the first inner container 273 and the second inner container 274, and the first content A1 and the second content A2 are discharged through the discharging member passing the stems 27 respectively.
For the first content and the second content, two liquid type hair dye or two liquid type permanent ingredients can be cited. Specifically, the two liquid type hair dye is composed of the first agent having alkaline property including the oxidation dye, and the second agent having acid property including oxidant such as hydrogen peroxide and etc.
As for the first agent of the two liquid type hair dye, the oxidation dye such as p-phenylene diamine, p-phenylene diamine sulfate, p-toluylene diamine, N, N-bis (2-hydroxyether)-p-phenylene diamine, N-phenyl-p-phenylene diamine, diaminodiphenylamine, 2-chrolo-p-phenyldiamine, N, N-dimethyl-p-phenylene diamine, p-aminophenol, m-aminophenol, o-aminophenol may be used as active ingredients. Further, the ingredient selected from the alkaline agent such as formula having amino group like ammonia, monoethanolamin, triethanolamine, diisopropanolamine, 2-amino-2-methyl-1-propanol, potassium hydroxide, sodium hydroxide, potassium carbonate, calcium carbonate, potassium hydrogen carbonate; stabilizing agent; other active agent; surface acting agent; alcohol; oil agent and etc. may be mixed with solvent such as water. The pH of the agent is preferable to be set between 8 to 12, more preferable to be set between 9 to 11.
As for the second agent of the two liquid type hair dye, ingredient selected from oxidant such as hydrogen peroxide, stabilizing agent, other active element, surface acting agent, alcohol, oil component or etc. may be mixed with solvent such as water. The pH of the agent is preferable to be set between 2 to 6, more preferable to be set between 3 to 5.
The first agent and the second agent of the two liquid type hair dye may be charged either of the first inner container and the second inner container. However, in order to maintain the hair dye effect by preventing the penetration of the ammonia, and prevent the gas pile formed by the generation of the oxygen, it is preferable to charge the first agent into the first inner container, and charge the second agent into the second inner container.
As for the propellant, a compressed gas of nitrogen, compressed air, carbon dioxide, nitrogen monoxide, and etc, and liquid gas of liquid petroleum gas, hydro fluoro olefin, and etc. can be cited. The propellant maintain the interior pressure of the outer container under 0.1 to 0.8 MPa, and the first agent and the second agent are stored under pressured state.
The aerosol container 270 has high gas barrier property and can at least stably store the content charged in the first inner container 273 for long period of time, because, the first inner container 273 at least equipped with the intermediate layer made of metallic foil. On the other hand, in the case where the content which generates the oxygen by the autoproteolysis of the hydrogen peroxide or such, is charged in the second inner container, the formation of the gas pile in the second inner container due to the generated oxygen can be prevented. Because the second inner container is equipped with a non metallic gas barrier layer (intermediate layer 278b) which prevents the penetration of the water property of moisture or humidity and allows the gradual penetration of the gas such as oxygen and ammonia, and because the generated oxygen can be gradually released to the outside of the second inner container. Therefore, the prevention of the gas pile prevents the splash of the content when discharging, and the decreasing of the volume of the second inner container together with the discharging of the content is secured. Further, the oxygen released from the second inner container 274 is trapped in the space S, and is prevented from penetrating into the first inner container, because the first inner container 273 and the second inner container 274 are inserted in the outer container 271. Further, the remaining amount of the contents may be visually verified by providing the transparent property to the outer container 271 and the second inner container 274.
The aerosol container 280 of
The second inner container 281 has an outer layer 282a made of synthetic resin, an intermediate layer made of non metal having gas barrier property, and an inner layer 282c made of synthetic resin. Such a second inner container 281 is manufacture by forming a three layered parison with the extrusion molding, and by using the direct blow processing which the parison is inflated by blowing the air inside. The second inner container 281 has flexibility and contracts with the pressure of the propellant.
The shape of the second inner container 281 will be the same cylindrical even if the second content is charged after the second inner container is contracted by vacuuming the air inside, because the second inner container is a flexible cylindrical container manufactured by blow processing. On the other hand, the shape of the first inner container will not be stabled in the regulated space of inside of the outer container, though the first inner container inflate in planular shape when the first content is charged, after the first inner container is stored in the outer container in folded state. Therefore, by adopting the second inner container 281 formed by blow processing, the first inner container 273 meats with the second inner container 281 like shown in
The aerosol container 280 also can prevent the penetration of the oxygen penetrated to the space S from the second inner container to the first inner container, and can prevent the gas pile formed in the second inner container, because, the first inner container 273 and the second inner container 281 is stored in the outer container 271. Therefore, it can prevent the splash of the content, and the volume of the inner container decreases along with the discharge of the content, and the remaining amount of the contents may be checked when the outer container is transmissive.
The aerosol container 285 of
By adopting the pleat part, the transformation of the volume before and after the charging of the content can be made large, and the shape of the expanded state and the contracted state is stable. Therefore, the use of the space in the outer container by two inner containers will be further effective.
In this case also, the penetration of the oxygen penetrated to the space S from the second inner container to the first inner container, and formation of the gas pile in the second inner container can be prevented.
The aerosol product 290 of
The aerosol product 290 of
The outer container 291 is substantially same as the outer container 91 of
In this embodiment, the whole of the outer container 291 is transmissive, therefore whole correspond to the outer window portion. However, because the valve assembly 296 is attached to the flange portion 291e or the neck portion 291e, the part from the bottom portion 291a to the shoulder portion 291c works as the outer window portion. Therefore, it is acceptable if at least one part of region from the bottom portion 291a to the shoulder portion 291d is transmissive, when the outer surface of the outer container is formed with printed matter, or is covered with a film or mark. The size and location of the outer window will not be limited, as long as it can see the second pouch from outside, such as hovering the outer window on the second pouch 293. Especially, the aerosol product 290 of
The first pouch 292 is equipped with a bag body 292a manufactured by bonding two sheet which is not transmissive, and a connecting member 292b engaged with the opening of the bag body.
The second pouch 293 is equipped with a bag body 293a manufactured by bonding two sheet with transparency, and a connecting member 293b engaged with the opening of the bag body. In this embodiment, the whole of the bag body 293a is transmissive, the whole of the bag body 293a works as inner window. However, the bag body 293a of the second pouch 293 only needs to have a part of transmissive part. More specifically, the part which contact with the dipping tube 297 has a transparency, when predetermined amount of the content is being discharged. The material used for the first pouch and the second pouch is that if it satisfies the transmissive property, the other is substantially same as pouch 46 of
The first content 294 is not limited, because it is charged into the first inner container. On the other hand the second content 295 is opaque. For such a first content 294 and the second content 295, two liquid type reaction agent such as two liquid type hair dye or two liquid type permanent ingredients in which the effects are obtained by blending can be cited.
In the aerosol product 290, the first pouch 292 and the second pouch 293 are filled with first content 294 and the second content 295, respectively, before the use. Therefore only the second content 295 of opacity can be seen from the inner window portion.
The first content 294 and the second content 295 are simultaneously discharged by lowering the discharging member opening both aerosol valve 15. Because the aerosol product 290 is objected to discharge two contents simultaneously, it is not necessary to check the remaining amount of the first pouch 292 as long as the remaining amount of the second pouch 293 can be verified. Therefore, only the description of the second pouch will be mentioned from now on.
The second pouch 293 is contracted as the both end of the side wall contact with each other, like if the second pouch 293 clip or nip the dipping tube 297, when the second content 295 is discharged form the second pouch 293 (see imaginary line of
In order to functions the first pouch 292 as a sign, the inner window must be configured to sight the first pouch 292 through the second pouch 293. On the other hand, in order to function the dipping tube 297 as the sign, the inner window must be configured according to the dipping tube 297 inserted in the bag body 293a. Specifically, because the dipping tube 297 is inserted along with the axis of the bag body 293a, it is preferable to have the inner window formed in the center of the width direction extending vertically. In this case, the inner window may not have to be provided in the both end of the side wall 293c, as long as the part of the side wall 293c facing the outer container is formed as a inner window.

The upper opening of the first path 356a is located away from the center axis of the rotating adapter 354 for engaging with the annual path 341a, and the lower opening is located away from the center axis of the aerosol container 330. In this embodiment, the distance from the center axis of the rotating adapter 354 to the upper end opening (radius of the annual path 341a) and the distance from the center axis of the rotating adapter 354 to the lower end opening (distance from center axis of the aerosol container 330 to stem 27) are same, and the first path 356a is a straight path penetrating the rotating adapter in vertical direction. Further, the lower end opening of the first path 356a is a stem inserting portion 357a in which the diameter is widened in lowering direction.
The upper opening of the second path 356b is located away from the center axis of the rotating adapter 354 for connecting the center path 341b, and the lower opening is located away from the center axis of the aerosol container 330 for connecting the stem 27. In this embodiment, the second path 356b is a path which has two turns communicating the upper end opening and the lower end opening. The lower end opening of the second path 356b is a stem inserting portion 357b in which the diameter is widened in lowering direction.

The valve assembly 462 is equipped with a valve holder 466 closing the outer container 461; two aerosol valves 15 independently held by the valve holder 466, and closing the inner container 412 respectively; and a mounting cover 97 covering the valve holder 466 and aerosol valve 15, fixing the aerosol valve to the valve holder 466, and fixing the valve holder to the opening of the outer container 461. The aerosol valve 15 and the mounting cover 97 are substantially same as the aerosol valve 15 and the mounting cover 97 of
The valve holder 466 comprises a base portion 467 of column shape, two holder portion 102 of tubular shape penetrating the base portion in vertical direction, and a positioning protrusion 38 extending upward from the top of the base portion. The holder portion 102 and the positioning protrusion 38 are substantially same as the holder portion 102 and the positioning protrusion 38 of
The base part 467 is composed of a plug portion 463 of tubular shape inserted into the outer container 461 along the inner surface 461 of the opening; a lid portion 103 of column shape arranged above the outer container 461; and a flange portion 103a formed between the plug portion and the lid portion extending outward in radius direction. The flange portion 103a is arranged on top of the mouth portion 461e of the outer container 461. The annual recessed portion 469 for holding the O-ring 105 is formed on the outer surface of the plug portion below the inner channel 465 when the valve assembly 462 is inserted or attached to the outer container 461. The lid portion 103 and the flange portion 103a are substantially same as the lid portion 103 and the flange portion 103a of
In such structured double aerosol container 460, the charging of the propellant into the space between the outer container 461 and both inner container will be simplify. That is, the propellant may be charged into space S from the clearance between the mouth portion 461e of the outer container 461 and the mounting cover 97 through the clearance between the mouth portion 461e of the outer container 461 and the flange portion 103a of the valve assembly 462 to the clearance between the inner surface 461f of the outer container 461 and the outer surface of the plug portion 463 of the valve assembly 462 (under cup charging, arrow direction of
After the fixing of the valve assembly 462 to the outer container 461, the air remaining in the first inner container 412 and the second inner container 413 are ejected using the pressure of the propellant by lowering stems 27 of the aerosol valves 15, and contents are loaded into the first inner container 412 and the second inner container 413 from stems to manufacture the double aerosol product.
The double aerosol container 460 can safely eject the propellant outside without letting the valve assembly 414 pop, when the aerosol container deforms due to the weakening of the outer container 461 caused by the heating such as temperature rise or etc. That is, when the neck portion of the outer container 461 expands, the lower end of the inner channel stirs downward, the contact between the O-ring 105 and the inner surface 461f of the outer container 461 let off, so the propellant can be ejected outside from the opposite route of the charging. Thus the propellant can be ejected outside before the valve assembly 462 jump off. Specifically, when the sealing effect is generated by having the O-ring 105 contacts with the inner surface 461f of the neck portion 461d, the sealing between the inner surface 461a and the plug portion 463 can be released at the early stage where the internal pressure is not yet abnormally high, and before the strength of the outer container is not yet weaken. Further, the vertical channel extending from the top may be formed on the outer surface of the mouth portion 461e of the outer container 461, like shown in
The aerosol container of
The double aerosol container 480 of
The double aerosol container 480 has a gasket 484 provided between the upper surface of the outer container 481 and the flange 013a of the valve assembly 482, like shown in
The double aerosol container 480 differs from the aerosol container 410 of
The outer container 481 is a pressure resistance container made of synthetic resin composed of a bottom portion, a barrel portion of tubular shape, a shoulder portion of tapered shape, a neck portion of cylindrical shape, and a thick mouth portion. The outer surface of the mouth portion 481e is protruded outwardly than the outer surface of the neck portion 481d. On the top surface of the opening 481k of the outer container, sealing protrusions 486 are formed concentrically (two rings in this disclosure). Further, a slit 487 penetrating the sealing protrusion 486 is formed extending in radius direction. Moreover, in the inner surface 481f structured by the inner surface of the neck portion 481d and the mouth portion 481e, a inner channel 488 is formed extending in vertical direction from the upper end. In this case also, it may be formed circularly. Additionally, in the outer surface of the mouth portion 481e, outer channels 489 are formed extending in vertical direction from the upper end, arranged annularly. The gasket 484 is arranged to cover the sealing protrusion 486, and the slit 487 forms above mentioned communicating path 485.
The valve assembly 482 is equipped with the valve holder 491 closing the outer container 481; two aerosol valve 15 held independently by the valve holder 491, closing the inner container 412, 413, respectively; and a mounting cover 97 covering the valve holder 491 and the aerosol container, fixing the aerosol valve 22 to the valve holder 91, and fixing the valve holder 491 to the opening of the outer container 481. The aerosol valve 15 and the mounting cover 91 are substantially same as the aerosol valve 15 and the mounting cover 97 of
The valve holder 491 comprises a base part 492 of column shape, two holder part 102 of tubular shape penetrating the base part in vertical direction, and a positioning protrusion 38 formed on the upper end of the base part extending upward. The holder part 102 and the positioning protrusion 38 are substantially same as the holder part 102 and the positioning protrusion 38 of
The base part 492 comprises a plug portion 493 of column shape, inserting into the outer container 481 along the inner surface 481f of the opening; a lid portion 103 of column shape, arranged above the outer container 481; and a flange portion 103a protruding outwardly in radius direction, formed between the plug portion and the lid portion. The flange 103a is arranged on top of the mouth portion 481e of the outer container 481 sandwiching the gasket 484. No sealing member of O-ring etc. is fixed on the outer surface of the plug portion 493. The lid portion 103 and the flange portion 103a is substantially same as the lid portion 103 and the flange portion 103a of
Because, the double aerosol container 480 is structured like above, it is easy to charge the propellant into the space S between the outer container 481 and both inner container. The slit 487 forms the communicating pathway 485 of the propellant on the upper end of the outer container 481, when the valve assembly 482 is held above such that the clearance is formed between the outer container 481 and the gasket 484, and the seal function between the mouth portion 481e of the outer container 481 and the gasket 484 is released, like shown in
After the fixing of the valve assembly 482 to the outer container 481, the remaining air in the first inner container 412 and the inner container 413 are ejected by lowering stems 27, and then, the contents are loaded into the first inner container 412 and the second inner container 413 through stems 27, which resultantly manufactures the double aerosol product.
The double aerosol container 480 can safely eject the propellant outside without letting the valve assembly 482 pop, when the aerosol container deforms due to the weakening of the outer container 461 caused by the heating such as temperature rise or etc. Specifically, when the outer container 481 deforms like show in
In this disclosure, the inner channel 488 and the outer channel 489 are formed on the outer container 481, however, these channels may be omitted. The charging of the propellant and the ejection of the propellant while deforming of the outer container can be performed, as long as the pathway (slit 487) communicating the inside and the outside of the outer container 481 is formed on the upper end surface 481k of the outer container 481. Further, a penetrating hole penetrating the inside and the outside of the mouth portion 481e or a sealing protrusion 481e having a low protrusion part made partially can be substituted for the slit 487. The slit 487 may be formed on the mouth portion of the outer container of
The aerosol container 490 of
As structured as above, the content loaded in the pouch 202 will not contact with the inner surface of the connecting member 205. Thus, the transmission of the content through the connecting member 205 will be prevented, and as a result, the degradation of the product is prevented. Further, although the element of one content passes through one pouch, the element will be prevented to intrude into the other pouch from the connecting member 205 attached to the other pouch. Therefore, the degradation of the product, due to the mixture of two contents can be prevented.
Additionally, in the aerosol container 490 (aerosol container 200), the lower end 217a of the holder part 217 of the valve holder 211 is formed to cover the top of the dipping tube 491 of the aerosol valve 15. In other word, the lower end 217a of the holder part 217 is located below the top of the dipping tube 491. Thus, the housing 26 will not be directly exposed in the space outside of the pouch, therefore, the transmissiveness of the content from the housing 26 is low.
Next, the other embodiment of the bag body of the pouch for the above mentioned aerosol container is disclosed.
The bag body 500 of
The bag body 500 is composed of a bonding part 518 where the periphery of two sheets 512a are bonded, and a storage part 519. The opening 516a of the bag body is formed of clearance made between the center of the upper part. In other words, both side of the bonding part 518 forms the barrel portion of the pouch. Additionally, by bonding the lower ends of sheets 512a which forms the lower end of the bonding part, constructs the barrel portion 518a. In this barrel portion 518a, two notches 515 are formed extending from the lower end extending vertically. Further, the thin bended line 515a is formed extending vertically parallel to the notched line. The bended line is a bended line elastically formed to have the bag body in open state. The bag body 500 may be inserted into the outer container in a folded state folded along the bended line or in curled state. In
The height of the bag body 500 is constructed to have it lower than the barrel portion of the outer container, in other word it is constructed to have it housed in the barrel portion of the outer container. Further, the bag body 500 is larger than the conventional one, in which the aerosol valve 15 is arranged some what higher (distance X of
The sheets 12a used for the pouch is substantially same as the pouch of
The aerosol container 520 of
The loading process of the content and the propellant are shown next. First, the pre-folded pouches 521 and the aerosol valves 15 are connected sandwiching the valve holder 96. In this state, the pouch 521 is held in the folded state with tapes or etc. Next, the valve holder 96 is held above the outer container 91 (see
In this state, aerosol valves 15 are held some what higher (distance X) than the holder part 102 of the valve holder 96 being supported by each of leg portion 518a of the pouch 521 on the bottom of the outer container 91. The propellant is charged into the outer container through the lower end of the mounting cover 97 through the holder part 102 of the valve holder (arrow of
After the charging of the propellant with the propellant charging machine, the aerosol valve 15 is then pressed to the outer container 91 (valve holder 96) side (downward), and the lower end of the mounting cover is crimped to the boundary of the neck portion and the mouth portion of the outer container 91, fixing the valve holder 96 and the aerosol valve 15 to the outer container 91. During this process, because the leg portion 518a of the pouch 521 deforms by absorbing the press force, the barrel portion of the inner container will not be bended or deform in disorder. As a result, the content which will be loader afterward can be smoothly loaded.
Lastly, the different kinds of two contents are loaded into the pouches 521 through stem 127 of aerosol valve 15. However, the contents may be loaded before the charging of the propellant. When the pouches are held in folded state with tapes and etc, the loading of the contents unfold the pouch.
Next inner container is another disclosure which can be used such for the inner container 12 of
The inner container 531 of
The inner container 531 comprises a bottom portion 531a, a barrel portion 531b of tubular shape, a shoulder portion of tapered shape formed on the top of the barrel portion, a neck portion 531d of tubular shape formed on the top of the shoulder portion, and an opening 531e of tubular shape having larger diameter than the neck portion. The lower side of the barrel portion 531b is formed in tapered shape where the diameter decreases downwardly. The pinch-off portion 532 is formed on the bottom portion 531a protruding downward. The pinch-off portion 532 has a plate shaped formed on the center of the bottom portion 531a, extending parallel with the diameter of the bottom portion. On the center of the pinch-off portion 532, the notch 533 is formed extending vertically from the lower end. The pinch off portion 532 is divided into two part by the notch 533, which enhance the flexibility when receiving the press force of vertical direction. In other word, the pinch-off portion 532 configures the leg portion of the present invention. Further, when using the inner container 531, the lower portion 533a of the pinch-off portion 532 divided by the notch 533, preferably deforms in curvature state or in bended state where each facing opposite, like show in
Further, the inner container 531 is configured so that the upper end of the inner container 531 protrudes when the inner container is placed on the bottom surface of the outer container.
Because the inner container 531 is stored with the lower part 531a of the pinch-off portion being folded, it can lower the possibility of the barrel portion of the inner container 531 to deform. Therefore, it prevent the linkage of the content while loading, and detachment or loosening of the aerosol container 15 and the inner container 531.
In this disclosure, the notch was made on the pinch-off portion, however, a horizontal bend line 533b, or recessed channel may be formed on the pinch-off portion 532 to give the elasticity deforming when receiving of the press force of vertical direction. The bend line or recessed channel may be shaped when forming the pinch-off part.
