2. Description of the Related Art Heretofore, an aerosol device has been used in which a container is filled with an undiluted solution such as general cosmetics and cosmetics for hair and is ejected through a valve with a propellant such as liquefied gas or compressed gas. Such an aerosol device is usually 30
It has a capacity of about 500 cc and is used little by little. In addition, as an aerosol device for indoor fumigation, a type in which the entire amount is injected at once is known.

[0003]

Since such an aerosol device is filled in a pressure-resistant container having a relatively high strength and is provided with an injection member such as an aerosol valve and a push button, the device is apt to be large and portable. It's inconvenient. Further, since the aerosol device contains a propellant, it cannot be distributed as a free sample in a small bag like a liquid cosmetic product. Also, if you pack only the undiluted solution in a small bag,
I do not know the characteristics such as the jetting state and the feeling when using aerosol. For this reason, when campaigning for a new product, some aerosol devices that indicate that they are for sample use should be placed on a showcase, etc., so that consumers can freely try them out. However, only some consumers who stop at the stores can try it.

Since the aerosol device cannot see the remaining amount of the contents, it can be opened by wrapping it with a transparent shrink film to show that it is not used or by opening a part of it, a so-called virgin cap. Many are provided. Therefore, when opened, it can be seen that the contents are new. However, since the content amount is relatively large as described above, when used little by little, even if a considerable period has passed after opening, it will be used as it is. Therefore, depending on the contents, there is a case where the contents are different from those in the initial state, such as changes over time or the composition of the contents is changed by spraying in an incorrect usage method. Further, even in the case of the above-described aerosol device for a sample, when it is used for trial by a small amount, it is not known when the opened aerosol product is used, so that consumers may become anxious about cosmetics and medicines.

The present invention can provide a usage condition almost equal to that of a general aerosol product, and is convenient for carrying,
The technical problem is to provide a packaging form and a device that uses the packaging form, which is low in cost even when distributed as a free sample and does not burden the consumer even when bringing back several kinds of free samples. Furthermore, the present invention provides the contents of an aerosol device,
It is also a technical issue to make it possible to use it immediately after opening it, and to reduce consumer anxiety.

[0016]

The operation device for a small pressure vessel of the present invention accommodates the small pressure vessel in the vessel receiving portion and uses the sealing portion opened by the opening means. In that state, since the small pressure vessel is movable in the axial direction, the seal portion can be indirectly opened by pushing the bottom portion of the vessel from the opening side of the vessel housing portion. Then, by indirectly operating the seal portion, the content can be ejected from the container body and the content can be ejected to the outside through the passage. Since the operation can be performed by simply pushing the bottom of the container in this way, the seal can be opened more easily than directly operating the small seal, and the stem can be pushed down in the axial direction surely to open the seal. be able to. According to the second aspect of the operating device of the present invention, since the container accommodating portion for accommodating the small pressure container having the seal portion opened by the tilting operation in a tiltable manner is provided, the bottom side can be tilted. You can make it gush just by moving.

In the case of the operating device in which the opening means has a fitting hole for fitting with the stem protruding from the upper end of the small pressure vessel, the small size is provided in the container storage portion with the stem fitted in the fitting hole. Set the pressure vessel. And in that state,

You can Furthermore, since it is provided with a grip, it is possible to aim and eject in a stable state.

The compact pressure vessel of the present invention has an internal volume of 0.5.
Since it is ~ 5 cc, which is much smaller than that of a conventional pressure vessel, it can be used as a one-time use pressure vessel. Further, since it is small, it is convenient to carry and can be used in combination with various operating devices for accommodating a plurality of small pressure vessels. When using a small pressure vessel by itself, connect a jetting member such as a push button equipped with a nozzle or spout to the outside end of the passage, and operate the seal part such as a valve from the outside to The contents can be ejected.

The seal portion is composed of a vertically movable stem and a valve rubber, and a small pressure is provided between the stem and the bottom portion of the container with a biasing means for biasing the stem upward. In the case of a container, the stem can be pushed in to open the seal portion, and when the pushing force is released, the biasing means restores the original state. Therefore, it is possible to inject little by little or all at once. In addition, since the biasing means is interposed between the bottom of the container and the stem, a relatively large biasing means can be used even in a small container, which stabilizes the return operation of the stem.

The seal portion is composed of a vertically movable stem and a valve rubber, and holds the stem upward at the bottom of the container and holds the stem in a lowered state when the stem is pushed. In the case of a small pressure vessel provided with means, there is less risk of accidentally pushing down the stem when not in use. Further, by only pushing the stem once, the injection state can be continued even after releasing the hand, and the entire amount can be injected. Further, since the inside of the container communicates with the outside at the time of disposal, there is no concern that the contents remain, and there is no risk of the container bursting when the container is crushed.

The contents can be ejected by opening the seal portion simply by operating the bottom portion laterally.

The connecting cartridge of the injection device of the present invention is
Since a plurality of jetting devices and those jetting devices are detachably connected, the plurality of jetting devices can be handled as a whole during transportation and storage, and can be cut and carried when used.

Since the connecting cartridge of the small pressure vessels of the present invention comprises a plurality of small pressure vessels and a supporting member connecting the small pressure vessels in a foldable manner, it can be manufactured or transported. It is possible to handle a plurality of items together during storage. On the other hand, when used, it can be set in the operating device as a whole, and depending on the operating device, each small pressure vessel can be broken off from the support member and individually set in the operating device for use. Further, by changing the shape of the supporting member, various small pressure vessels can be formed into a connecting cartridge.

In the second aspect of the connecting cartridge of the small pressure vessels of the present invention, adjacent small pressure vessels are directly separably connected without using a supporting member. for that reason,
The connecting cartridge for the small pressure vessel can be made smaller. Further, since the small pressure vessels are connected in a line, the feeding mechanism for feeding the small pressure vessels in sequence can be simplified.

The intermediate body of the connection cartridge for the small pressure vessel of the present invention is provided with a plurality of small pressure vessels by folding the container connection body and the lid connection body at the hinge portion and closing the container with each lid body. It is possible to produce multiple cartridges at once. In that case, it is possible to fill each container of the container connected body with the stock solution in advance and then cover the container connected body with the lid connected body. Then, after that, a propellant such as compressed gas or liquefied gas can be filled from the valve of each lid of the lid connected body.

In this case, it is possible to freely select which of the small pressure vessels 12 is ejected by operating the finger to be pressed. That is, they may be operated one by one, or may be operated all at once. Therefore, the injection amount or the type of the undiluted solution to be ejected may be appropriately selected according to the object to be ejected.

FIG. 4 shows a preferred embodiment of the small pressure vessel 12 used in the above injection device 10. The small pressure vessel 12 includes a bottomed cylindrical container body 15 and a valve 30 arranged so as to close an upper opening of the container body. The valve 30 is mounted in an annular valve rubber 31 engaged with the upper end of the container body 15, a cover 32 for fixing the valve rubber 31 to the container body 15, and a central hole of the valve rubber 31. The stem 18 is provided.

The outer periphery of the upper portion of the container body 15 has a somewhat large diameter, and is provided with an annular step portion 33 for engaging the lower end of the cover 32. The lower portion of the cover 32 is caulked to the lower surface of the stepped portion 33 to attach the valve rubber 31 and the stem 18 to the container body 15. Further, in this embodiment, a support rib 35 for supporting the inner side of the valve rubber 31 is projected from the bottom portion 34 of the container body 15. The support ribs 35 are annularly arranged via a slit for communicating the inside and the outside thereof.

Further, a holding member 36 is projectingly provided at the center of the bottom portion 34 of the container body 15. The holding member 36 has a substantially columnar shape, and has a shape of a rugby ball in which the central portion in the height direction is slightly swollen. A deep hole 38 for receiving the holding member 36 is formed in the lower portion 37 of the stem 18. The lower portion 37 of the stem 18 is composed of, for example, an elastic piece divided by a slit, and can be elastically deformed to the extent that the holding member 36 is received. Therefore, in the state of FIG. 4 in which the stem 18 is rising, the lower end of the stem 18 is abutted to prevent the lowering of the stem 18, but when the stem 18 is strongly pushed down, the lower end of the stem 18 is elastic as shown in FIG. 5a. The shape is such that the stem 18 can be held in a depressed state by covering the holding member 36 while being expanded. The holding member 36 can be formed integrally with the container body 15, but it may be formed separately as shown in FIG. 5b. Further, as shown in FIG. 5c, the holding member 36 and the lower portion 37 of the stem are
The locking portions 36a and 37a may be formed on the.

As shown in FIG. 4, the upper portion of the stem 18 has a bottomed cylindrical shape having a center hole 40, and an annular groove engaging with the inner edge of the valve rubber 31 is provided at an intermediate position in the longitudinal direction. 41 are formed. The annular groove 41 and the central hole 40 communicate with each other through a stem hole 42. Stem hole 42
Is always sealed by the valve rubber 31. The shape of the upper portion of the stem 18 is almost the same as the conventional one.

In this small pressure vessel 12, the stem rubber 31 seals the stem hole 42 when the stem 18 is not operated, and the inside and outside of the vessel are not in communication with each other. Since the lower portion 37 of the stem 18 is engaged with the upper end of the holding member 36, the stem 18 is erroneously
Even if external force is applied to the stem 18, it is difficult for the stem 18 to fall. On the other hand, when the stem 18 is pushed down intentionally, the lower end 37 of the stem 18 is expanded by the upper end of the holding member 36 and fitted around the holding member 36 as shown in FIG. 5a. Thereby, the stem 18 is maintained in the depressed state.

When the stem 18 is maintained in the depressed state as described above, the valve rubber 31 is bent downward, the stem hole 42 is opened, and the inside and outside of the container body 15 communicate with each other. Thereby, the content is ejected to the outside through the stem 18. This ejection continues until the entire contents of the container have been ejected. That is, this small pressure vessel 12
In the injection device 10 using, the small pressure vessel 12 is used up, and when the entire amount is injected, a new small pressure vessel 12
To replace. At that time, the small pressure vessel 12 can be taken out by inserting a finger through the hole 24.

Although the small pressure vessel 12 of FIG. 4 is a full-volume injection type, a small pressure vessel of the type that injects only when the stem is pushed may be adopted. The small pressure vessel 45 shown in FIG.
A spring 46 as an urging means is interposed between the stem 18 and the bottom portion 34 of the container body 15. In this embodiment, the spring 46 is a compression coil spring. An annular step portion 47 that engages with the upper end of the spring 46 is formed at the lower end of the stem 18, and an engaging protrusion 48 that engages with the spring 46 is provided at the center of the bottom portion 43 of the container body. It may be an engagement hole. Instead of the coil spring, a spring made of rubber or synthetic resin having the same form as the holding member of FIG. 4 can be used. In this embodiment, thin support ribs 35a for supporting the inner edge of the valve rubber 31 are radially provided from the inner surface to the bottom surface of the side wall of the container body 15. However, as shown in FIG. 4, the support ribs 3 are arranged in an annular shape.
It may be 5. Other parts are the same as the small pressure vessel 12 of FIG.

In this small pressure vessel 45, the spring 46 constantly urges the stem 18 upward. Then, only when the stem 18 is pushed down against the urging force of the spring 46, the stem rubber 31 can be elastically deformed to eject the contents. When the force of pushing down the stem 18 is weakened, the stem 18 moves upward due to the urging force of the spring 46, and the ejection is stopped. This small pressure vessel 45 is also the operating device 1 of FIG.
1 can be attached and used.

The small pressure vessel 45b shown in FIG. 6b is a fixed-pressure injection type small pressure vessel. The small pressure vessel 45b is
With respect to the small container 45a of FIG. 6a, a cylindrical partition wall 44,
The annular packing 25 fitted in the annular groove formed on the outer periphery of the lower part of the stem and the inner surface of the partition wall 44 are the annular packing 2
The size is set so that 5 can be fitted tightly. Support ribs 35 a are integrally provided on the upper and lower portions of the partition wall 44, are formed separately from the main body 15, and are fitted into the main body 15. Other parts are the same as the small pressure vessel 45 of FIG. 6a. By fitting the annular packing 25 into the partition wall 44, the partition wall 44 is closed, and the inside of the container body is filled with the upper chamber 26.
And the lower chamber 27. When jetting this small pressure vessel 45b in an inverted state, the stem 18 is attached to the annular packing 2
By pushing down 5 so as to fit into the partition wall 44, only the quantified contents stored in the upper chamber 26 are jetted. Such a small pressure vessel is preferably used for products in which the amount of the active ingredient used at one time is limited, for example, pharmaceutical products and quasi drugs. Further, when the amount used per day is limited, it is also possible to fill the small pressure vessel 45b with an amount usable per day and inject it for a quantitatively determined number of times.

The injection device 50 shown in FIG. 7 has an operating device 51 having a cylindrical shape with a bottom and a storage portion 13 for storing one small pressure vessel 45, and FIG.
The small pressure vessel 45 of FIG. The depth of the storage part 13 is
The depth is such that only the upper portion of the small pressure vessel 45 can be accommodated, and therefore the lower portion of the small pressure vessel 45 is exposed.
A fitting hole 19 for fitting with the stem 18, a vertically oriented passage 20,
The lateral passage 21 and the nozzle 14 are the same as in the case of the operating device 4 in FIG. This injection device 50 is
As shown by an imaginary line, the bottom portion of the operating device 51 and the bottom portion of the small pressure vessel 45 can be operated by pinching them with fingers. That is, it can be said that the operating device 51 is a push button. The entire injection device 50 including the push-button type operating device 51 may be housed in the housing portion 13 of the "grip" -shaped operating device 11 in FIG. In that case, the opening may be simply provided without providing the injection nozzle 14 on the side surface of the operating device 51.

All of the above small pressure vessels can be used upside down and no dip tube is used. However, when the valve housing and the dip tube are adopted like the conventional aerosol product, it can be used in the upright state. In addition, a double aerosol product using a so-called piston or inner bag may be used so that it can be used in any orientation.

The injection device 55 shown in FIG. 8 is a box-shaped operating device 56, a small pressure container 58 housed in a housing portion 57 of the operating device, and a pusher mounted on the stem and the upper part of the small pressure container 58. It is composed of a button 59. The operating device 56 includes a main body 60 and an openable / closable lid body (cover) 62 connected to an end of the main body by a hinge or a joint 61. A plurality of the storage portions 57 are arranged on the upper surface of the main body 60 in an aligned state. Further, the storage portions 57 are communicated with each other by a groove 64 for storing a support member described later. On the side surface of the main body 60, an opening portion 65 corresponding to each storage portion 57 is provided. Storage part 5
The depth of 7 is shallower than the height of the small pressure vessel 58 with the push button 59 attached. Therefore, the bottom of the small pressure vessel 58 projects from the main body 60 in the stored state.

A push button 59 is attached to each small pressure vessel 58, as shown in FIG. 9a. The push button 59 has substantially the same form as the injection device 50 of FIG.
It is provided with a fitting hole for fitting with the stem, a vertical passage, a lateral passage, and an injection nozzle 14. The push buttons 59 are connected to each other by the support member 6 as shown in FIG. 9a.
The plurality of small pressure vessels 58 are connected to each other to form a connection cartridge 67 as a whole. In this embodiment, as shown in FIG. 9b, six small pressure vessels 58 are arranged in two columns vertically and three columns horizontally. However, the number of columns and rows may be three or four or more. The support member 66 includes one trunk portion 68 extending in the left-right direction and a plurality of branch portions 69 extending laterally from the trunk portion 68. Each branch 69 can also serve as a sprue or a runner when the push button 59 is manufactured by injection molding. In addition, it is preferable that the branch portion 69 is formed so that the base portion thereof can be easily broken off from the push button 59. As a result, it can be used alone as a small pressure vessel 58 with a push button by breaking it off from the branch portion 64. In that case, the push button 59 itself becomes the operating device, and the small pressure vessel with the push button becomes the injection device.

In this injection device 55, when the small pressure vessel 58 protruding above the main body 60 is pushed down, the small pressure vessel 58 is pressed downward against the push button 59. Thereby, the stem of the small pressure vessel 58 is pushed, and the contents are jetted from the jet nozzle 14 of the push button 58 through the opening 65. Since this injection device 55 has a box-shaped form, it can be used as a case for storing and carrying the small pressure vessel 58. Further, since the plurality of small pressure vessels 58 are integrally connected by the support member 66, they can be housed in the housing portion 57 of the operating device 56 at one time. The groove 64 then houses the support member 66. It is also possible to provide an inner lid (not shown) on the inner surface of the lid body 60 and close the lid body 60 together with the inner lid so that all the small pressure vessels 58 are simultaneously jetted.

Each of the above-mentioned small pressure vessels has a stem, but like the small pressure vessel 70 shown in FIG.
Those without a stem can also be adopted. The small pressure vessel 70 includes a bottomed tubular container body 15 and a valve body 71 made of an elastic material such as rubber or synthetic resin disposed at an upper end thereof.
And a cover 32 for fixing the valve body 71 to the container body 15. The cover 32 is made of, for example, a metal plate. The central portion 72 of the valve body 71 has a lens shape, and elastically contacts the opening 73 at the central portion of the cover 32 from below. Thereby, the sealing action is secured between the cover 32 and the valve body 71. The thick annular portion 74 around the valve body 71 acts as a packing that seals between the container body 15 and the cover 32. The reference numeral 74a is a communication hole formed in the valve body 71.

In such a small pressure vessel 70 having no stem, the stem 18 is fixed on the operating device side, the stem 18 is passed through the central opening 73 of the cover 32, and the central portion 72 of the valve body 71 is inserted. Keep it in contact. When the bottom side of the container body 15 provided upside down is pushed down, the valve body 71 is supported by the stem 18, so the valve body 71 is pushed down in FIG. 10, and the lower end of the cover 32 and the center of the valve body. The seal of the portion 72 is opened. Thereby, the container body 15
The contents inside pass through the communication hole 74a, pass through the inside of the stem, and are ejected to the outside. When the force of pushing down the container body 15 is weakened, the elasticity of the valve body 71 raises the container body 15 to its original position, and the injection is stopped. This small pressure vessel 70 is
Since it has no stem, it can be manufactured at low cost.

The small pressure vessel 75 shown in FIG. 11 a is a ball holding member 76 that also covers the upper portion of the container body 15 and also serves as a gasket, and a cover 3 that fixes the ball holding member 76 to the container body 15.
2 and the ball 7 held by the ball holding member 76

A passage 78 communicating between the inside and the outside of the container is formed, and a spherical recess 7 for holding the ball 77 elastically and airtightly is formed in the passage 78.
9 is formed. This one also has no stem. Therefore, it is used for operating devices with stems. Also,
In this embodiment, all parts of the container body 15, the cover 32, the ball holding member 76 and the ball 77 are made of synthetic resin. Therefore, there is no need for separate disposal. In addition, also in other embodiments such as FIGS. 4 and 6, all parts can be made of synthetic resin. In those cases, it is more preferable that the synthetic resins of all the parts are composed of the same or the same synthetic resin.

In the small pressure vessel 75 of FIG. 11a, the ball 77 is airtightly held in the recess 79 in a normal state, so that the inside and outside of the vessel are sealed. And the stem 18
The stem 18 is attached to the operating device having the above in a state of being fitted to the upper portion of the passage 78. When this is pushed into the bottom of the container body 15, the stem 18 of the operating device pushes the ball 77 into the container as shown in FIG.
8 communicate. The communication state is maintained even when the hand is released from the bottom of the container body.

The small pressure vessel 75a shown in FIG. 12a uses, instead of the above-mentioned ball support member 76, a bottomed cylindrical seal member 76a whose bottom is closed by a thin film 77a.
The other parts are similar to the small pressure vessel 75 of FIG. 11a.
This is a stem with a sharp tip 1 as shown in phantom.
It is mounted upside down on the operating device equipped with 8a so that the stem 18a faces the space 78a above the sealing member 76a. When the bottom of the small pressure vessel 75a is pushed in in this state, the tip of the stem 18a breaks the thin film 77a of the seal member 76a, and communicates the inside and outside of the vessel (see FIG. 12b). As a result, the contents are ejected from the stem 18a through the passage of the operating device. 10, 11a and 12
Since the small pressure vessels 70, 75, 75a of a have no stem, they have few parts, and can be manufactured lightweight and at low cost.

In this case, when the uppermost small pressure vessel that has been jetted is removed, the lower small pressure vessel rises in order. In such an injection apparatus, it is more preferable to provide a mechanism for repelling the uppermost small pressure vessel after further pulling the trigger 85 for injection.

FIG. 15 shows a connecting cartridge 88 of a small pressure vessel used in the operating device 87 of FIG. 14a.
This small-sized pressure vessel connecting cartridge 88 is formed by connecting a plurality of small-sized pressure vessels 81 with each other by a connecting portion 89 that can be folded. The connecting portion 89 connects the container bodies 15 of the small pressure container. The connecting cartridge of the small pressure container can integrally form the container body 15. In addition, when the container body 15 is filled with the stock solution and further with the propellant through the valve, the container body 15 can be filled at the same time and can be handled as a so-called integral part. Therefore, manufacturing is easy. However, in some cases, for example, the cover 32 of FIG.
You may make it connect mutually. When using the connecting cartridge 88 of such a small pressure vessel, as shown in FIG.
More preferably, the operating device 87 is provided with a mechanism for injecting the uppermost small pressure vessel and disconnecting the small pressure vessel from the immediately lower small pressure vessel.

FIG. 16 shows a small pressure vessel 81 connected by a supporting member 66 similar to that shown in FIG. In the case of FIG. 9b, the push button 59 is connected to the support member 66, but in this embodiment, the container body 1
5 is connected to the support member 66. This can also be handled integrally when the container body 15 is filled with the stock solution or the propellant.

The intermediate body 91 of the connected cartridge for the small pressure vessel shown in FIG. 17A is composed of a plate-shaped first base 92 and a plurality of vessel main bodies 1 arranged on the first base 92.
5 is integrally formed with the container connecting body 93, a plate-shaped second base 94, and the container body 15 on the second base.
