本発明は、エアゾール製品の噴射装置に関し、

More particularly, it relates to a device for ejecting an aerosol product as a stable mist or foam of the same pressure and composition throughout.

とき、霧または泡沫を形成する。 Generally, aerosol products use Freon-12, Freon-11, Freon-11, or Freon-12 as propellants.
114 (trade name of a DuPont product), liquefied gases such as propane, isobutane, normal butane, methyl ether, or compressed gases such as carbon dioxide, laughing gas (N 2 O), and nitrogen. It is dissolved or dispersed in a stock solution in a container, and forms a mist or foam when the valve of the container is opened and the internal pressure injects it.
ところで、エアゾール製品の内で、噴射剤が40

安定した霧または泡沫が得られる。 By the way, among aerosol products, propellants account for 40%.
In insecticides, hair sprays, etc. that contain ~50% or more, the pressure inside the container is maintained above a certain level from the beginning to the end of spraying, so a stable mist or foam with the same composition can be obtained until the end.

合にはスプレー状態の著しい劣化が起こり、炭酸
ガスのように原液に対して若干溶解する圧縮ガス
を用いた場合でも同様の劣化が避けられない。 On the other hand, aerosol products such as shaving foams and glass cleaners generally have a low propellant content due to the low solubility of the gas in the stock solution.
15% or less, and for these products, the volume of the contents including gas must be 70 to 70% of the container before use.
However, with use, the volume occupied by the contents decreases and, conversely, the volume occupied by the space phase increases.
The pressure within the container decreases by the increased volume of the spatial phase, and to compensate for this, the liquefied gas dissolved or dispersed in the stock solution evaporates to maintain an equilibrium state. However, such evaporation reduces the gases dissolved or dispersed in the stock solution, which may result in changes in the composition of the mist or foam of the aerosol product being sprayed outside the container, or in some cases, The liquid may be sprayed as a liquid instead of turning into mist or foam, or it may remain in the container due to insufficient gas pressure. In addition, when a compressed gas such as nitrogen gas that is hardly soluble in the stock solution is used as a propellant, the spray condition deteriorates significantly, and when a compressed gas such as carbon dioxide that is slightly soluble in the stock solution is used as a propellant. Similar deterioration is unavoidable.

置が提案されている（例えば特公昭50−26773号
公報、特公昭51−23052号公報等）。 In order to solve the above-mentioned problems, a device has been proposed that prevents the internal pressure from decreasing due to the increase in the spatial phase by providing a liquefied gas filling tank in the aerosol container (for example, Japanese Patent Publication No. 50-26773). Publications, Special Publications No. 51-23052, etc.).
しかしながら、これらの液化ガス補給装置は複
雑な構成を有し、正確な作動を期待することがで

う欠点がある。 However, these liquefied gas replenishment devices have a complicated structure, and not only cannot be expected to operate accurately, but also have the disadvantage that their manufacturing costs are high.
本発明の目的は、エアゾール製品の噴射に伴う

圧力かつ同一組成の安定した霧または泡沫を噴射
させる装置を提供することにある。 It is an object of the present invention to provide a device that prevents pressure reduction in a container due to spraying of an aerosol product and sprays a stable mist or foam of the same pressure and composition from beginning to end.

とができることを見出した。 The present inventor has proposed an aerosol injection device consisting of a pressurized chamber and a content storage chamber, in which the content storage chamber is filled with an aerosol stock solution and a propellant of 15% or less with respect to the stock solution, and when in use, the pressurized chamber is It has been found that the above object can be achieved by filling the pressurized chamber with liquefied gas so that the pressure is higher than the pressure of the content storage chamber.

霧または泡沫を噴射させることができる。 That is, according to the present invention, when the content is injected through the valve of the aerosol container, the volume of the content occupying the content storage chamber decreases, and the pressure in the content storage chamber tends to decrease by the volume. At that time, the liquefied gas in the pressurized chamber evaporates and vaporizes, corresponding to the volume reduction of the contents of the storage chamber, and the equilibrium state between the contents storage chamber and the pressurized chamber is maintained, and the pressure inside the chamber is reduced to the point where all the contents are It is maintained almost constant without decreasing until it is injected, and a stable mist or foam having the same composition can be injected until the end.

In addition, the liquefied gas to be filled into the pressurized chamber in the apparatus of the present invention includes Freon 11, Freon 12, Freon 114, liquefied propane, isobutane, n-butane, dimethyl ether, etc. Preferably, the pressure is also selected to be higher, for example by 0 to about 1 kg/cm 3 .
