[Industrial Application Field] The present invention relates to a method for producing aerosol products such as cosmetics, pharmaceuticals, household goods, and foods. [Prior Art] Conventionally, in aerosol products, a double-structure type aerosol product has been put into practical use as a method for taking out the contents to be sprayed. As a form of separating the concentrate and propellant to be released in a container,
There is a method using a valve or piston can having an interior of plastic film or metal film (Japanese Patent Publication No. 12571/1971). Here, liquefied gases such as Freon 12, 14, 114, propane, butane, nitrogen, carbon dioxide, air, etc. are used as propellants. In addition to these aerosol-type valves, valves can also be made by storing the contents to be released in a bag made of flexible plastic or rubber, or by containing a ring-shaped rubber and applying the restoring force of the rubber to the bag. ``Celbag'' (1986-156577) ``Excel'' whose contents are released when the valve is opened.
(Jikai 57-501469) There are systems, etc. [Problems to be solved by the invention] In the case of aerosol products, as means for pressurizing,
It is common to use liquefied gas by adjusting the internal pressure to 3 to 6 kg/ cm2 , but when a flexible inner bag is used, the gas permeates through the film of the bag and the contents and gas are separated. The result is that the two are not substantially isolated. Similarly, in the case of piston cans,
A similar phenomenon occurs when gas permeates the small gap between the inner wall of the container and the outer periphery of the piston. In this case, even after the contents are used up, the liquefied gas remains in the container, so if the used container is disposed of in a fire or the like, an accident may occur. In addition, if non-flammable Freon 12, 11, or 114 is used, it may cause pollution by depleting the ozone layer outside the atmosphere, and propane and butane are flammable, so there is a potential fire hazard. In addition, in the case of the above-mentioned "Celbag" or "Excel" system that utilizes the restoring force of tubular rubber, the restoring power of the rubber is limited and can only withstand a maximum pressure of approximately 3 kg/ cm2 , and it is the most elastic of the materials. Although high-quality natural rubber is used, it gradually deteriorates due to exposure to air, ultraviolet rays, etc., and its restoring force decreases due to permanent elongation, and the injection pressure tends to decrease over time, resulting in the content not being able to be injected. It is inevitable that the remaining amount of [Means for solving the problem] The present invention does not use gas as a pressurizing means because the aerosol type is undesirable from the viewpoint of the above-mentioned pollution problem, danger to consumers such as bursting during disposal, and environmental conservation. , which utilizes the restoring force of foamed elastomer. That is, in the present invention, a valve attached to an inner bag for storing the contents to be released into a pressure-resistant container is attached, and the elastomer is foamed in the space between the outer pressure-resistant container and the inner bag under normal pressure or pressurization. , an aerosol product in which the contents are press-fitted into an inner bag. As the elastomer foam, natural rubber, synthetic rubber such as isoprene rubber, or elastic foam such as urethane foam is foamed in the space between the pressure-resistant container and the inner bag by a normal foaming method. The desired pressure can be obtained by calculating the foaming volume in advance for the desired pressure and performing foaming. Since the pressure resistance of a general pressure-resistant aerosol container is 13 Kg/cm 2 , if the pressure is within this range, the required injection state can be sufficiently obtained. Examples of manufacturing the aerosol product of the present invention are shown in Fig. 1-A.
This will be explained by F. Hollow tin pressure container 1
Pour the elastomer compound (foaming stock solution) 2 to be foamed into the upper opening of the container 1, then insert the inner bag 4, made of plastic or metal, for example, with a valve 3, and seal the opening of the container with a crimp. D. Next, the elastomer compound 2 is foamed in the space 5 between the pressure-resistant container and the inner bag, and then the contents to be sprayed, such as water, are injected into the inner bag 4 to obtain the aerosol product of the present invention. . FIGS. 2A to 2D are diagrams for explaining another embodiment of the present invention, in which the elastomer compound 2 to be foamed is poured into the pouring mold 6A from the upper opening, and then the inner bag having the valve 3 is inserted. 4 and close the upper opening of the mold. C. The elastomer compound 2 is foamed in the space 5 between the mold and the inner bag. D. After the foaming is completed, the mold is removed. E. The foam including the inner bag is placed in the outer case 7. The aerosol product of the present invention is obtained by storing the inner bag 4 and finally pressurizing the contents to be sprayed, such as alcohol, into the inner bag 4. Therefore, the pressure container of the present invention may be of a decomposable type when the elastomer is foamed. The present invention will be explained in more detail with reference to the following examples. Example 1 Stock solutions KE52A and KE52B (trade names, both manufactured by Shin-Etsu Chemical Co., Ltd.) to give silicone rubber foam
Immediately introduce the creamy mixture before foaming into the space between the 250ml pressure-resistant container and the inner bag, place the inner bag to be filled with the contents inside the pressure-resistant container, seal it, and foam it. was press-fitted into the inner bag through the valve at a pressure of about 7 kg/cm 2 . The pressure inside the inner bag is
A fine mist was obtained when sprayed at 4.0Kg/cm 2 (25°C). Example 2 Stock solutions A and B having the following composition were mixed, introduced into a 250 ml pressure-resistant container, an inner bag was attached, the container was sealed and foamed, and alcohol was then pressurized into the inner bag. The mixing ratio of the stock solutions A and B, the internal pressure of the inner bag, and the spraying condition of the injection device containing this urethane rubber foam are as follows. Stock solution A: Urethane prepolymer NCO (10%) Stock solution B: Silicone blowing agent (L-520), catalyst (triethylamine), water

The present invention foams an elastomer such as rubber or plastic in the space between a pressure-resistant sealed container and an inner bag stored in the container to form an elastic body, and uses its restoring force to pressurize the inner bag and release the contents. It is designed to be released. Suitable materials for the elastomer include materials with low toxicity and high elasticity, such as natural rubber, various synthetic rubbers, and urethane foam. Foam contains air bubbles,
The container is in a compressed state, and the restoring force of the container to return to the unpressurized state is used to release the contents from the valve. Tubular rubber that is currently in practical use and left in a stretched state inevitably suffers permanent elongation over time, but in the present invention, it is extremely stable, although this varies depending on the material of the elastomer and the foaming method. This gives you the resilience you need. When foaming at a high foaming density in a sealed container with a constant volume, the pressure increases more than when foaming freely under atmospheric pressure, and the pressure applied to the inner bag can be increased, increasing the pressure resistance of the container. It is possible to increase the foam density to the limit. When using liquefied gas, the pressure changes greatly depending on the temperature, and a normal aerosol container has a deformation pressure of up to 13 kg/ cm2 , but the product pressure has to be adjusted in consideration of temperature changes.
The product pressure is designed to be 3 to 5 kg/cm 2 at 25°C, but with the present invention, it is not necessary to take into account changes in pressure due to temperature changes, so a product pressure of 9 to 10 kg/cm 2 can be designed, and the pressure can be adjusted depending on the product. It is possible to obtain the fine dry mist that is required. In general, products such as antiperspirants, hair sprays, deodorants, and insecticides that require a fine dry mist can also be commercialized using new packaging that does not require conventional aerosol packaging. Ta. Since aerosol products use liquefied gas, they are required not to be left at temperatures above 40°C, but they may explode if accidentally mixed in a bonfire, exposed to direct sunlight on the coast in midsummer, etc. There have been a number of accidents, such as waste cans bursting on cleaning trucks and causing car fires. In the present invention, since gas is not used as a pressurizing means, there is no risk of accidentally throwing it into a fire.
The packaging is extremely safe as the container will not be destroyed even by sudden temperature rises. To further increase the safety level, if a small hole is provided in a part of the container after foaming is completed, a sudden rise in internal pressure due to heating etc. can be prevented, making it even safer. Further, if the foam is solidified after foaming is completed, the foam will not be ejected from the container. Unlike aerosol formats, it provides consumers with extremely safe packaging.
