Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention stores fluid substances such as gases and liquids in a pressure-tight container under pressure, and releases the sealing of the pressure-tight container when necessary. This invention relates to a pressurized discharge container that discharges a fluid substance to the outside.

(Prior Art) Conventionally, various types of spray containers using fluorocarbon gas as a pressure medium have been widely used as containers of this type. However, it has become known that fluorocarbon gas destroys the ozone layer in the atmosphere, and there is a sudden movement to completely abolish fluorocarbon gas in order to protect the global environment, and there is a strong desire to develop a pressurizing means to replace fluorocarbon gas in spray containers. There is.

As an example of this pressurizing means, a structure recently adopted for cosmetic spray containers is that a balloon-like inflatable plastic container is suspended inside a pressure-resistant container, and a pipe-shaped inflatable container is placed around the plastic container. A rubber container as thick as possible is provided, liquid or cream cosmetics are filled from the outside of the pressure container under high pressure into the plastic container, and as the plastic container expands, the rubber container is expanded. The pressure container is sealed while maintaining the expansion of the container.
When necessary, for example, by pressing a nozzle stopper at the upper end of the pressure-resistant container, the cosmetic is discharged from the plastic container to the outside.

(Problem to be Solved by the Invention) However, in such conventional dispensing containers, the rubber container must be shaped like an extremely thick pipe, and therefore, it is extremely difficult to fill the rubber container with a fluid substance such as a cosmetic. High pressure is required, and new expensive equipment is required in addition to the conventional filling equipment for fluid substances. In addition, since the rubber container is thick, the internal volume is small, and the amount of fluid substance filled is significantly reduced compared to conventional containers. Furthermore, there is a drawback that the discharge pressure decreases during repeated use.

The present invention was made in view of the above-mentioned drawbacks, and its purpose is to form a pressurizing means without using fluorocarbon gas, and to have a relatively large internal volume of a fluid substance as a content. , and adjust the internal pressure appropriately depending on the contents.
As it is changeable, the discharge pressure can be maintained at a high level until the end of discharging the contents, and furthermore, the discharge pressure of the contents is not generated during storage or when not in use, allowing safe storage or effective use of the discharge pressure. It is an object of the present invention to provide a pressurized discharge container for a fluid substance that can be used to discharge a fluid substance under pressure.

A storage container is provided, and a means for sealing the storage part is provided, and when necessary, the sealing means is moved from the outside of the pressure container to release the seal, and the plurality of substances can be mixed. It is set up.

(Function) By moving and mixing the sealing means, the seals of multiple substances that generate gas are released.

Next, the plurality of substances are mixed to generate gas,
Increase the internal pressure inside the pressure vessel. In this state, when a part of the pressure container is opened during use, the fluid substance inside is discharged to the outside due to the above-mentioned internal pressure.

It has become.

That is, in this example, the top plate 24 and the packing material 25 constitute a means for sealing the storage section, and the shaft portion 21, crosspiece 26, etc. constitute a means for moving the sealing means. .

Next, to explain the use of the above embodiment, after manufacturing the pressurized discharge container for a fluid material according to the present invention and before using it for the first time, the rotating frame 2o is positioned at the lowest position as shown in FIG. position, and the upper surface openings of the first storage part 14 and the second storage part 15 of the airtight plug body 10 are connected to the top plate 24 of the rotating frame 20.
It is sealed via a packing material 25.

In use, as shown in Figure 2, the airtight plug 1
When the crosspiece 26 of the rotating frame 20 at the bottom of the frame 0 is rotated to raise the rotating frame 20, the upper end of the airtight plug 10 is opened, so that the first substance 16 in the first storage part 14 and the second substance 16 in the second storage part are separated. 15
The second substance 17 in the liquid is in a state where it can be mixed. Therefore, when the pressure container 1 is turned upside down or tilted and shaken, the first substance 16 and the second substance 17 are mixed, carbon dioxide gas is generated due to the chemical reaction between the two substances, and this gas is transferred to the airtight rising valve 5. Accumulates downward and increases pressure. Then, this pressure urges the airtight rising valve 5 upward with a strong force, and the airtight rising valve 5 moves upward while sliding along the inner wall of the pressure container 1, compressing the fluid substance 7 under pressure. . The fluid substance 7 also fills the space 4e of the spray mechanism 4.

In this state, the push button 4 at the top of the pressure container 1 is pressed.
When a is pressed downward, the spring 4d is compressed and the shaft portion 4b
descends, and the fluid substance 7 is discharged to the outside from the nozzle hole 4f through the nozzle 4c.

The pressure inside the pressure vessel 1 is reduced by this discharge of the fluid substance 7 to the outside, but as mentioned above, the gas generated and accumulated below the airtight rising valve 5 causes the airtight rising valve 5 to rise and the fluid substance to be released. 7 is maintained under pressure. Note that the amount of gas generated is almost proportional to the amount of the first substance 16 and the second substance 17, so the amounts of the two substances 16 and 17 are set in relation to the volume of the pressure vessel 1. , internal fluid substance 7
It is necessary to create a pressure such that the liquid is completely discharged.

Incidentally, if the entire container can be made of synthetic resin as in this embodiment, manufacturing can be facilitated and costs can be reduced.

Furthermore, if the fluid substance 8 to be filled contains a solvent or the like,
At least the surfaces of at least the outer shell 2 and the parts that come into direct contact with the substance 7, such as the airtight rising valve 5, are coated, or the whole part is molded using a resin with good chemical and solvent resistance. There is a need.

It communicates with a discharge passage for fluid substance 7 formed in .

By using this bag body 28, the airtight raising valve 5 used in the first embodiment is omitted. The other configurations are the same as in the first embodiment.

In this second embodiment, the rotating frame 20 is raised as in the first embodiment, and when the first substance 16 and the second substance 17 are mixed and carbon dioxide gas is generated, this gas compresses the bag body 28. Therefore, when the push button 4a of the pressure container 1 is pressed down, the fluid substance 7 inside is discharged by the pressure of the carbon dioxide gas.

According to this embodiment, since the fluid substance is stored in the bag, for example, if polyethylene or the like is used as the bag 28, it is suitable for storing contents such as food that should not come into direct contact with the inner wall of the pressure container. ing.

In addition, the bag body 28 is made of chemical-resistant material such as aluminum sheet.

When a material with good solvent resistance is used, the contents do not come into contact with the inner wall surface of the pressure container, so even resins with poor chemical resistance can be used as the resin constituting the pressure container, and the container can be manufactured at a low cost.

In this embodiment, an airtight plug 10a similar to that of the first embodiment is provided, and the upper end opening of this airtight plug 10a is opened by lifting a rotating frame 20a having a structure similar to that of the rotating frame 20 of the first embodiment. It has become so. However, unlike the case of the first embodiment, the rotating frame 20a in this embodiment is provided with two through holes extending from the center of the top plate 24a to the outer periphery of the upper end of the shaft portion 21. ing. Further, the outer circumferential surface of the top plate 24a extends to the inner wall of the outer shell 2 of the pressure vessel 1, and an O-ring 30 is interposed therein, so that the pressure vessel 1
The space above the O-ring 30 in the pressure vessel 1 is kept airtight with respect to the space below. A fluid substance 7 is filled above the rotating frame 20a,
Further, a tube 31 is vertically provided on the lid member 3 of the pressure-resistant container 1 and communicates with the discharge passage for the fluid substance 7. The lower end of this tube 31 terminates at the upper surface of the top plate 24a. The other configurations are the same as in the first embodiment.

In this third embodiment, similarly to the first embodiment, the rotating frame 2
0a is rotated upward to sufficiently separate the top plate 24a from the upper end of the airtight plug 10a, and the pressure container 1 is shaken to remove the first substance 1.
When 6 and the second substance 17 are mixed, the carbon dioxide gas generated thereby passes through the through hole 29 of the top plate 24a and directly mixes with the fluid substance 7 above it, thereby pressurizing it. Next, cover member 3
When the push button 4a attached to the press button 4a is pressed down, the pressurized fluid substance 7 is discharged from the tube 31 to the outside through the discharge passage.

According to this embodiment, the contents and the high-pressure gas are in a mixed state, so it is particularly suitable for foam-like contents such as mousse.

10 and 11 show a fourth embodiment of the present invention. The pressurized discharge container for a fluid substance in this embodiment has a metal body 32 and an outer cylindrical shell 33. The metal body 32 is a cylindrical body with an open top and bottom, and its diameter is reduced at the top, and a metal lid member 3a is caulked to the top surface. The outer periphery of the metal body 32 is covered with an outer shell cylinder 33 made of synthetic resin such as plastic. The outer peripheral surface of the outer shell cylindrical body 33 is decorated with designs, etc., in order to improve the decorativeness. Further, the lower end of the outer shell cylindrical body 33 extends downward from the lower end of the metal body 32, and a female thread 34 is formed on the lower inner peripheral surface thereof. Further, a male thread lla is formed on the lower outer periphery of the airtight plug body 10 and is threadable with the female thread 34 of the outer shell cylinder 33, and both threads 34. By screwing lla together, the airtight plug 10 is fixed to the outer shell cylindrical body 33, thereby closing the opening bottom of the metal body 32. Further, the upper portion of the shaft portion 21 of the rotating frame 20 is configured to be in airtight contact with a seal ring 23a mounted on the upper inner wall of the through hole 18 of the airtight plug body 10. Further, the airtight rising valve 5a is formed of metal, and its central upper surface is provided with four parts corresponding to the spray mechanism 4.

The other configurations are the same as in the first embodiment.

According to this embodiment, since the inside of the container is made of metal,
Even if the filled fluid substance is mixed with a solvent or the like, the inner wall surface will not be eroded, and the strength is strong, so the gas barrier property against high pressure gas generated inside is improved. In addition, since the high-pressure gas generated inside is received by the metal inner container, a resin with low pressure resistance and chemical resistance is used as the resin constituting the outer shell cylinder 33 located outside. This makes it possible to reduce the thickness of the wall. Furthermore, by using resin for the outer wall of the pressure container, a desired design can be made for the appearance of the container.

It should be noted that various modifications of the present invention are possible in addition to the above embodiments. For example, as a modification of the first embodiment, in the first embodiment, the shaft portion 21 of the rotating frame 20 is inserted into the through hole 18 of the airtight plug body 10. Although it is screwed together with the airtight plug body 10, the two are just a tight fit,
The rotating frame may be forcibly pushed into the interior so that the rotating frame slides and the first substance 16 and the second substance 17 can be mixed.

(Effects) As described above, according to the pressurized discharge container for a fluid material of the present invention, a plurality of fluid materials that generate gas by mixing are placed inside the pressure container that seals and stores the fluid material as the content. In addition to providing a storage section for storing multiple substances, the storage section is also provided with a means for sealing multiple substances, so when filling fluid substances such as liquid or cream into a pressure-resistant container, it is possible to use a general-purpose filling container. A special pressurizing device is not required. Furthermore, during storage or when not in use, the contents can be safely stored or transported without generating discharge pressure.

Furthermore, if necessary, the means for sealing the storage area of the plurality of substances is moved from the outside of the pressure-resistant container, the sealing of the plurality of substances is released, gas is generated inside, and the fluidity is increased by the pressure of this gas. The substance is now discharged to the outside. Therefore,
Since the gas generation port can be adjusted according to the amount of multiple substances, the internal pressure can be changed appropriately according to the contents, and the discharge pressure can be maintained at a high level until the end of the discharge of the contents. I can do it.

Furthermore, since the amount of the substance that generates gas by mixing is relatively small, the internal volume of the fluid substance can be increased.
