  The present invention relates to a mechanism for maintaining an aerosol container valve in an open state, a replacement aerosol container including the valve opening mechanism, and an aerosol container replacement system.

JP-A-11-105954 JP2002-80079

  In the aerosol-type discharge container of Patent Document 1, a cylindrical attachment member is attached to an attachment ring of an aerosol container, and the discharge member is fastened by a screw portion formed on the upper portion of the attachment member. Therefore, the discharge member can be attached and detached with the screw portion. In addition, after the contents are exhausted, the discharge member can be reused by removing the discharge member and mounting it on a new container. Furthermore, when the container body is metallic and the discharge member is made of resin, the metal portion and the resin portion can be easily separated and collected.

  Patent Document 2 discloses an aerosol container capable of continuously spraying a spraying amount of a chemical solution or the like as necessary. In this device, a male screw is formed at a cylindrical outer peripheral portion that holds a housing at the center of the mounting cap, and a stem is arranged at the top of the cylindrical head. And when the cylindrical pressing member provided with the internal thread which can be screwed together with the said external thread is screwed together, it is comprised so that the said stem can be pushed down. Therefore, once the pressing member is attached, the stem is also kept pressed down, and the contents can be continuously ejected. When it is desired to stop the injection, the screw can be loosened to stop the injection. Therefore, there is little waste of injection.

  In the above-mentioned patent document, a screw mechanism is used to make it easier for the user to remove the injection member, so that the reuse of the injection member is separated and the metal aerosol container and the synthetic resin discharge member are separated into separate resources. Protect and realize. On the other hand, in the aerosol apparatus, when it becomes unnecessary and is discarded, it is necessary to discharge the aerosol composition remaining in the container. Failure to do so will cause the aerosol device to be compressed and damaged in the garbage collection vehicle when the collection company collects the aerosol device, and the aerosol composition remaining inside the container will be released in the collection vehicle, causing static electricity around it. If there is a fire type such as, there is a risk of igniting and causing a fire. Such dangers hinder the promotion of resource protection.

  The discharging operation of the aerosol composition can be realized even if a hole is made in the container body or the spray button is continuously pressed, but this takes time. In addition, in order to pursue only the ease of discharging work, simply adding a member for that purpose to the aerosol device will always provide a member that is not used until the discharging work, and the overall design or convenience of the product Sexuality is impaired. Therefore, it is necessary to provide a device that satisfies both the effective use of the aerosol device and the discharge operation.

  Therefore, the present invention has been made in view of such problems, and is a valve opening mechanism that enables the discharge of the aerosol composition with a simple operation, and the effective use of the aerosol device without being troublesome at the time of discharge. It is an object of the present invention to provide a replacement aerosol container and an aerosol container replacement system that simultaneously satisfy both the discharge operation and the discharge operation.

  The valve opening mechanism of the present invention (Claim 1) comprises an attachment member attached to the upper end of the aerosol container around the stem of the aerosol valve, and a discharge member detachable by the attachment member and a screw mechanism. The mounting member includes a peripheral wall that extends above the top of the container and has a threaded portion, and the discharge member includes a cylindrical portion that is screwed with the threaded portion of the peripheral wall of the mounting member, and an upper end of the cylindrical portion. There is provided a top plate to be connected, a stem holding portion which is connected to the passage in the stem by fitting with the stem and formed with a communication passage which opens toward the peripheral wall, and the discharge member is screwed to the mounting member. Sometimes, the stem holding part is configured to open the aerosol valve.

  In such a valve opening mechanism, the discharge member is configured to be able to change into a normal form that is spaced above the stem with respect to the mounting member and an open form that pushes the stem downward. (2) is preferable. In addition, it is preferable that the discharge member is provided with a raising member that can be screwed to the attachment member and can be removed at the lower end of the cylindrical portion. Further, it is preferable that the cylindrical portion of the discharge member includes a side wall member extending in the opposite direction beyond the top plate, and the side wall member can be screwed with a screw portion of the peripheral wall.

  A replacement aerosol container according to the present invention (Claim 5) includes the above-described valve opening mechanism and an aerosol container to which the valve opening mechanism is attached. Further, the aerosol device according to the present invention (Claim 6) includes an aerosol container equipped with the above-described mounting member, and an injection member that is detachably screwed with a screw portion of the mounting member and is fitted to the stem.

  The valve opening mechanism of the present invention (Claim 1) is a stem that is simply mounted by removing the injection member and turning the discharge member around the mounting member when discharging the contents (aerosol composition) from the aerosol device that is no longer needed. Is pushed down, the aerosol valve is opened, and the entire contents remaining in the container can be discharged. For this reason, since it is possible to perform a simple operation by simply tightening the screw, it does not take time for the discharging operation. In addition, the screw mechanism is firmly fixed by the screw mechanism, and furthermore, the distance to which the stem is pushed down is smaller than the rotation distance when the discharge member is mounted, so the stem hole is opened slowly and the contents are large. The contents can be discharged safely, such as being prevented from being discharged and scattered. In addition, since the discharge member has a stem holding portion formed with a communication passage that is fitted to the stem when attached to the attachment member, communicates with the passage in the stem, and opens toward the peripheral wall of the attachment member. The contents to be collided with the peripheral wall do not scatter.

  Further, when the discharge member is configured to be able to change with respect to the attachment member into a normal form arranged at an interval above the stem and an open form in which the stem is pushed down (Claim 2). ) Can be used as a cap to protect the stem in the normal form, and also as a cap to protect the injection member because an injection member such as a push button can be attached to the stem, thus preventing erroneous injection. In addition, it is easy to pack or transport and is suitable for distribution. On the other hand, when the aerosol device (product) becomes unnecessary and the contents are discharged, the discharge member is changed to the valve open form. Thereby, the aerosol composition can be easily discharged.

  When the discharge member is provided with a raising member that can be bent and removed from the lower end of the cylindrical portion (Claim 3), the discharge member is normally used as a cap that protects the upper part of the container, such as erroneous injection. To prevent. And at the time of discharge | emission operation | work, an aerosol composition can be easily discharged | emitted by removing a raising member and mounting | wearing with an attachment member. Therefore, it is possible to realize use as a normal cap and use as a discharge member in a discharge operation without increasing the number of parts. When the tubular portion of the discharge member includes a side wall member extending in the opposite direction beyond the top plate, and the peripheral wall of the side wall member and the mounting member can be fastened by a screw mechanism (Claim 4), It becomes a cap which covers an injection member and prevents unexpected accidental injection. And if it turns over, it will act as a discharge member which discharges the contents. Therefore, it is possible to immediately discharge the aerosol composition without preparing a discharge member separately.

  The replacement aerosol container of the present invention (Claim 5) has the above-described valve opening mechanism and an aerosol container to which the valve opening mechanism is attached. Therefore, when the aerosol device becomes unnecessary, the remaining contents can be easily discharged. Furthermore, the aerosol device of the present invention (Claim 6) uses the screw part formed on the mounting member to detach the injection member, so that the user selects various injection members according to the purpose of injection. can do. Furthermore, after the aerosol composition is exhausted, the spray member can be reused by removing the spray member and mounting the spray member on a new aerosol container. The aerosol container that is no longer needed can be equipped with a discharge member to discharge the entire remaining aerosol composition and discard it. Further, when the container body is metallic and the injection member is made of resin, the metal portion and the resin portion can be easily separated and collected as resource garbage. Therefore, it is easy to recycle and suitable for resource protection.

  The aerosol container replacement system of the present invention (Claim 7) comprises the above-described replacement aerosol container (A) and the above-mentioned aerosol device (B), and the discharge member and the aerosol device of the replacement aerosol container (A). The injection member (B) can be replaced. Therefore, when the aerosol composition in the aerosol device (B) is exhausted, the user prepares a replacement aerosol container (A), removes the discharge member of the replacement aerosol container (A), and uses the used aerosol container. The aerosol composition remaining in the container is discharged by attaching to the attachment member of the container (B). Next, the injection member attached to the used aerosol device (B) is attached to the replacement aerosol container (A) and used as a new aerosol device. In this way, the used aerosol container provides the injection member and the replacement aerosol container provides the discharge member. Therefore, since the injection member is reused, it is suitable for resource protection. In addition, the discharge member is not attached at the time of use, and it is attached to the replacement aerosol container at the time of replacement of the aerosol container, so there is no need to always have a discharge member that is not used at the time of use, so the overall design of the product Or convenience is not impaired.

It is sectional drawing which shows other embodiment.

  An embodiment of the valve opening mechanism of the present invention will be described with reference to FIG. A valve opening mechanism 1 shown in FIG. 1 includes an attachment member 2 and a discharge member 3 that is detachably attached to the attachment member 2. Note that the attachment member 2 and the discharge member 3 are formed of, for example, a polyolefin such as polyethylene or polypropylene, or a synthetic resin such as polycarbonate, polyamide, or polyester.

  Such a valve opening mechanism 1 uses the aerosol composition 7 (contents) filled in the aerosol container 6 shown in FIG. 2b, and the aerosol remaining in the aerosol container 6 when no longer needed. Used to discharge composition 7. The aerosol container 6 in FIG. 2b includes a container main body 4 and an aerosol valve 5 fixed to an opening formed in the upper part of the container main body 4. The aerosol container 6 is filled with an aerosol composition 7. The container main body 4 can use a conventionally well-known thing. For example, the container body 4 may be a known one having a bottomed cylindrical shape having a pressure resistance made of a metal such as aluminum or tin, a synthetic resin, pressure-resistant glass, or the like. The container main body 4 shown in FIG. 2b is provided with a shoulder 4a at the upper end, and a bead 4b is formed at an opening further above the shoulder 4a. The aerosol valve 5 includes a mounting cup 8 that is crimped to the bead 4b, a housing 9 that is held by the mounting cup 8, a stem 10 that is provided in the housing 9 so as to be vertically movable or tiltable, and the stem 10 that is always attached. A well-known thing which has a spring biased upward can be used. The aerosol valve 5 includes a covering portion 8a formed at the upper end of the mounting cap 8, and a side wall portion 8b extending downward from the covering portion 8a. The covering portion 8a is connected to the container body via a gasket. No. 4 bead 4b and the side wall 8b is crimped to the bead 4b of the container body 4 so as to be airtightly attached to the container body 4. When an injection member such as a push button is attached to the stem 10, it can be used as an aerosol device.

  The aerosol composition 7 filled in the aerosol container 6 comprises a stock solution containing an active ingredient and a propellant for injecting the stock solution in a desired jet form such as foam, mist, or mist. Active ingredients for hair such as styling agents, treatment agents, hair dyes, depigmenting agents, colorants, moisturizers, antipruritic agents, analgesics, anti-hot flashes, antiperspirants, pest repellents, refreshing agents, cleansing agents A stock solution containing active ingredients for skin, such as hair restorers, insecticides, deodorants, and fragrances, and a propellant such as liquefied gas or compressed gas for injecting the stock solution It consists of.

  From here, it demonstrates using FIG. 1 and FIG. The mounting member 2 includes an annular mounting portion 2a mounted on the upper end of the aerosol valve 5, and a cylindrical peripheral wall 2b extending upward from the mounting portion 2a. The mounting portion 2a is a cylindrical member, and elastically clamps the outer periphery of the covering portion 8a of the mounting cap 8 at the lower end thereof. A male screw 2c is formed on the outer periphery of the peripheral wall 2b.

  The discharge member 3 is a bottomed cylindrical member, and includes a cylindrical portion 3a fastened to the peripheral wall 2b of the mounting member 2 by a screw mechanism, and a top plate 3b that connects the cylindrical portion 3a upward. On the inner peripheral surface of the cylindrical portion 3a, a female screw 3d that is screwed with a male screw 2c formed on the peripheral wall 2b of the mounting member 2 is formed. The top plate 3b is formed with a stem holding portion 11 communicating with the stem 10 extending from the vicinity of the center toward the inside of the cylinder, and an opening 3c penetrating the top plate 3b. The opening 3c is provided in order to discharge the propellant of the aerosol composition 7 discharged into the discharge member 3 when the discharge operation is performed. The stem holding part 11 has a columnar shape, and a fitting part 11a for fitting with the stem 10 is formed at the lower end of the cylinder. An upper portion of the stem 10 is inserted into the fitting portion 11a, and a step portion 11b that can push down the distal end portion of the stem 10 is formed at the end portion of the insertion. In the vicinity of the center of the step portion 11b, a communication passage 11c that is recessed upward from the tubular portion 3a is formed so as to be continuous from the passage of the stem 10. The communication passage 11c is formed so as not to interfere with the upper portion of the stem 10 when the step portion 11b pushes down the stem 10. A slit-shaped discharge port 11d is formed on the outer periphery of the columnar stem holding portion 11 so as to communicate with the communication path 11c. The discharge port 11d is cut out with a length from the lower end of the stem holding part 11 to the communication path 11c until it reaches the fitting part 11a. The discharge ports 11d are provided at three locations and are oriented in three directions at equal angles from the outer periphery of the stem holding portion 11.

  The aerosol container 6 is sold as a replacement aerosol container with the mounting member 2 attached and the discharge member 3 as a set. The user attaches and uses an injection member such as a push button removed from the used aerosol device to the stem 10 of the newly purchased aerosol container 6. The injection member may be sold separately or sold as a set with the aerosol container 6. In the used aerosol device, the user removes the injection member from the stem 10 and screwes the discharge member 3 into the mounting member 2. As a result, the stem holding portion 11 disposed at the center of rotation of the discharge member 3 naturally fits with the stem 10. The screwing depth at this time is configured so that the aerosol composition 7 can be discharged by sufficiently pushing down the stem 10, but is preferably configured not to exceed the stroke in which the stem 10 moves up and down. In this embodiment, although the discharge port 11d extends in three directions, the size of the discharge port 11d may be increased or the number of passages may be increased in the case of providing the aerosol composition 7 that is difficult to discharge. On the other hand, if the aerosol composition contains a lot of flammable components (alcohols, hydrocarbons, liquefied gas, etc.) and is released into the atmosphere, the safety will decrease when the concentration increases. The number of outlets 11d may be reduced or reduced. In addition, it can replace with slit shape and can also use a hole. For the same reason, the diameter of the gas vent opening 3c can be increased or formed at several locations on the top plate 3b.

  As shown in FIG. 2 b, when the discharge member 3 is screwed to the mounting member 2, a discharge chamber 12 is formed by the top plate 3 b of the discharge member 3, the cylindrical portion 3 a, and the upper portion of the mounting cap 8. At this time, as the screw is tightened, the stem holding portion 11 of the discharge member 3 pushes the tip of the stem 10 downward at the stepped portion 11b. When the stem 10 is pushed downward, the inside of the container body 4 and the discharge chamber 12 communicate with each other through the discharge port 11d and the communication passage 11c, the inner passage of the stem 10, and the stem hole. If it does so, the aerosol composition 7 discharged | emitted from the discharge port 11d will collide with the surrounding wall 2b of the attachment member 2, and will stay in the discharge chamber 12 as it is. Among the aerosol composition 7, the propellant and volatile components are discharged and exhausted into the atmosphere from the opening 3c of the top 3b. Therefore, when performing the discharge process, the discharged aerosol composition 7 is not scattered and the finger of the handle is not soiled, so that it is clean. Moreover, since the attachment member 2 and the discharge member 3 are fastened by the screw mechanism, the discharge operation can be performed safely at the time of disposal. In order to prevent the contents discharged into the discharge chamber 12, particularly the stock solution, from overflowing the discharge chamber 12 and contaminating the aerosol device and its surroundings, absorbent materials such as water-absorbing resin, cotton, and paper are placed in the discharge chamber 12. It is preferable to discharge after inserting.

  Further, since the opening 3c (see FIG. 2a) for venting is formed in the top plate 3b, even if the screw part is screwed by holding the cylindrical part 3a of the discharge member 3 in the hand, The handle part is not touched. Therefore, even when the discharge operation of the aerosol composition 7 is stopped once in the middle, the discharge can be stopped by grasping the outside of the cylindrical portion 3a and loosening the screwing. As shown in FIG. 2a, when the opening 3c is arranged so as to avoid the extended line in the discharge direction of the discharge port 11d (X in FIG. 2a), liquid or solid contents are less likely to leak from the opening 3c.

  In addition, although the discharge member 3 mentioned above has pushed down the front-end | tip part of the stem 10 by the step part 11b, it is a pushbutton type which is exhibiting the columnar shape like the past, and the injection hole is formed in the side surface. This injection member can also be used when attached to the stem 10. In that case, it is good to form the protruding part which pushes down the said push button in the top plate 3b, push down a push button from the upper part by the protrusion, and to discharge the aerosol composition 7. Furthermore, although the male screw 2c is formed on the mounting member 2 and the female screw 3d is formed on the discharging member, conversely, the female screw may be formed on the mounting member 2 and the male screw may be formed on the discharging member. Further, the mounting member 2 and the discharge member 3 can be formed of a transparent material so that the inside of the discharge chamber 12 can be visually recognized. Even if the discharge chamber 12 is not formed, the aerosol composition 7 will not be scattered even if the cylindrical portion 3a of the discharge member 3 is disposed in front of the discharge hole 11d so as to block the injection direction. In that case, the cylindrical portion 3a may be formed to have a substantially cylindrical shape by a plurality of plate-like pieces, and the female screw 3d may be formed inside the plate-like piece, even if the cylindrical portion 3a does not have a cylindrical shape. In this case, since the gaseous component such as the propellant escapes from the gap between the plate-like piece and the plate-like piece, it is not necessary to provide the opening 3c therefor.

  FIG. 3 shows an embodiment of the replacement aerosol container of the present invention. Among the replacement aerosol containers 15 shown in FIG. 3, the same components as those in the valve opening mechanism 1 in FIG. As shown in FIG. 3 a, the attachment member 2 is attached to the top of the aerosol container 6, and the discharge member 16 is attached to the attachment member 2. The discharge member 16 can be changed into two forms: a normal form A that is arranged so as to leave a gap between the stem holding part 11 and the stem 10, and a stem open form B that pushes down the stem 10. In the normal form A, the stem holding portion 11 may be fitted to the stem 10 as long as the stem 10 is not pushed down.

  FIG. 3 b shows the discharge member 16 used in the replacement aerosol container 15. A plate-like raising member 17 extending downward is formed at the lower end of the cylindrical portion 3a. The raising member 17 extends downward along the peripheral edge of the cylindrical portion 3a, and a female screw continuous with a screw portion formed on the inner surface of the cylindrical portion 3a is formed on the inner surface thereof. FIG. 3a shows a state in which the discharge member 16 having the raised portion 17 is screwed to the mounting member 2 (normal form A). In its normal form A, the discharge member 16 is used as a cover that protects the top of the can. Therefore, erroneous injection is prevented, and transportation and packaging are easy.

  Further, the raising member 17 is formed with a groove along the boundary portion or a fine notch for bending at the boundary portion with the cylindrical portion 3a, and when the bending portion is bent at the boundary portion, The raising member 17 can be bent and removed (see FIG. 3b). When the raising member 17 is removed, the shape becomes substantially the same as that of the discharge member 3 of FIG. 1, and the discharge work can be performed by attaching to the attachment member 2 as shown in FIG. 3c (stem open form B). The raising member 17 is formed by extending a plurality of plate-like pieces from the lower end of the cylindrical portion 3a. However, the raising member 17 is predetermined from the lower end of the cylindrical side wall extending downward from the lower end of the cylindrical portion 3a. Slits may be formed at intervals of.

  FIG. 3d shows an aerosol device 18 fitted with a valve opening mechanism. The aerosol device 18 includes an injection member 19 at the top of the head, and a discharge member 16 is disposed so as to cover the injection member 19. The raising member 17 of the discharge member 16 extends greatly downward (see FIG. 3e). Therefore, even in a state where the injection member 19 is still attached to the aerosol device 18, the discharge member 16 can be directly covered with the injection member 19 to obtain the normal form A. On the other hand, when the aerosol composition 7 is discharged, the injection member 19 must be extracted from the stem 10, but as described above, the raising member 17 can be removed and the valve opening configuration B can be changed. In the aerosol device 18 configured as described above, the discharge member 16 is normally used as a screw-type cap that protects the upper portion of the injection member 19. Therefore, since the discharge member 16 is effectively used in both cases of normal and discharge, the beauty or convenience of the aerosol product as a whole is not impaired.

  FIG. 4 shows an embodiment of an injection member used in the replacement aerosol container 15 of the present invention. The injection member 21 shown in FIG. 4a includes a tubular portion 3a and a plate-like connecting member 22 that is continuous with the upper end of the tubular portion 3a and extends beyond the top of the container body with one end serving as a fulcrum 21a. ing. A cylindrical nozzle 22 a extends upward from the vicinity of the center of the connecting member 22. The other end of the connecting member 22 is provided with a stopper 21b for preventing the connecting member 22 from tilting with the fulcrum 21a of the connecting member 22 as a fulcrum when not in use. A stem holding part 11 is formed in the lower part of the cylindrical nozzle 22a. The fitting portion 11a connected to the stem 10 of the stem holding portion 11 is formed in a tapered shape that spreads from the inside toward the outside, and has a structure that does not easily come off from the stem 10 even if the stem holding portion 11 tilts. ing. A discharge hole 22b is formed at the tip of the cylindrical nozzle 22a and communicates with the stem 10. The fitting portion 11a of the stem holding portion 11 can be used for aerosol containers having different diameters or heights of the stem 10, and the fitting portion 11a is deformed by repeated use. Insert an elastic body 21c (for example, an O-ring) such as synthetic rubber, natural rubber, silicon rubber, or elastomer so that the aerosol composition 7 does not leak from the mounting portion when the injection operation is performed so as not to deteriorate. Is preferred.

  When the ejection member 21 configured in this manner is pulled out of the stopper 21b, the connecting member 22 can tilt with the fulcrum 21a as a fulcrum toward the portion where the stopper 21b is disposed. At this time, when the operation portion 22c provided on the side surface of the nozzle 22a is pushed downward with the finger, the stem holding portion 11 pushes the tip of the stem 10 downward, so that the inside of the main body container 2 communicates with the discharge hole 22b. The aerosol composition 7 is discharged. 4b and 4c show another form of the injection member. The injection member 23 shown in FIG. 4b injects the contents in the form of mist or mist, and a nozzle provided with a mechanical breakup mechanism is inserted into the injection hole 23a. By selecting the size of the injection hole 23a, the shape of the mechanical breakup mechanism, and the like, a desired injection form (fog spreading, etc.) can be obtained. Further, by using a straight nozzle having no mechanical breakup mechanism or a long nozzle as the nozzle, the nozzle can be dripped in a coarser mist or droplet. Moreover, the injection member 24 shown in FIG. 4c has a trigger 24a in the operating portion, and when the trigger 24a is pulled, the stem 10 is tilted. Since any of the injection members has a screw portion that can be attached to and detached from the attachment member 2, various injection members can be used for the replacement aerosol container 15 by utilizing the male screw 2 c formed on the attachment member 2. it can. In other words, if a female screw that can be screwed with the male screw of the mounting member 2 is provided at the lower part of the injection member, the user can attach and use the injection member that can select a desired injection according to the application. Can do.

  Next, FIG. 5 shows a schematic diagram of a replacement system for the replacement aerosol container 15 and the aerosol device 20 to which the injection member 23 is attached. The process from when the aerosol device 20 is used until it is discarded will be described. In the state S1 shown in FIG. 5, the aerosol composition 7 of the aerosol device 20 is almost used up and a replacement aerosol container 15 is newly prepared. Next, in state S2, the ejection member 23 is removed from the aerosol container 6 of the aerosol device 20, and the discharge member 16 (normal form A) is removed from the aerosol container 6 'of the replacement aerosol container 15. In state S3, the injection member 23 is screwed into the newly prepared attachment member 2 of the aerosol container 6 'and reused. On the other hand, the discharge member 16 removes the raising member 17 and is screwed into the unnecessary aerosol container 6 (stem open state B). Then, the screw is tightened as it is, and the remaining aerosol composition 7 is discharged to the outside. Thus, since the injection member 23 is attached to the new aerosol container 6 'one after another, there is no waste and it is suitable for resource protection. On the other hand, the discharge member 16 can also be usually sold in the normal form A, and the discharge member 16 can be used as a cover for protecting the upper portion of the stem 10, so that not only unexpected injection is prevented, but also packing or transportation. Is easy to distribute. If the discharge member 16 is made of the same material as the aerosol container 6, it can be discarded while attached to the aerosol container 6. Thereby, the waste disposal contractor can know that the aerosol composition 7 in the aerosol container 6 has been discharged, and can treat it with peace of mind. However, after the aerosol composition 7 has been sufficiently discharged, the discharge member 16 may be removed from the aerosol container 6 ', and the metal aerosol container 6' and the resin injection member 23 may be separated and discarded.

  In the case of the valve opening mechanism 1 shown in FIG. 1, first, the user sets the aerosol container 6 to which the attachment member 2 is attached and the discharge member 2 that is not screwed with the attachment member 2. Buy. Next, the prepared injection member is separately attached to the attachment member 2 and used as an aerosol device. And when an aerosol product becomes unnecessary, an injection member is removed, the said discharge member 2 is screwed together, and after discarding the remaining aerosol composition 7, it is discarded.

  FIG. 6 shows still another embodiment of the valve opening mechanism. Since the valve opening mechanism 25 shown in FIG. 6 is substantially the same as the valve opening mechanism 1 of FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted. The discharge member 26 of the valve opening mechanism 25 shown in FIG. 6 includes a side wall member 26a in which the cylindrical portion 3a extends in the opposite direction beyond the top plate 3b. On the inner peripheral surface of the side wall member 26a, a female screw 3d that can be screwed with the male screw of the mounting member 2 is formed.

  The valve opening mechanism 25 shown in FIG. 6 a fastens the side wall member 26 to the male screw 2 c of the mounting member 2. At this time, the stem 10 is arranged with a space (reference L in FIG. 6) from the top plate 3b, so that it does not interfere with the stem 10 (normal form A). Therefore, even if the stem 10 is pushed downward by mistake, the injection of the aerosol composition 7 can be prevented. FIG. 6 b shows a state where the aerosol composition 7 is discharged using the discharge member 26 (stem open form B). In FIG. 6 b, the discharge member 26 is obtained by turning the discharge member 26 shown in the normal form A upside down and fastening the female screw 3 d of the cylindrical portion 3 a to the male screw 2 c of the mounting member 2.
