Description

【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、密封容器内にアルコール水溶液を噴射剤と
共に充填したアルコール系エアゾールの改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an improvement in an alcohol aerosol in which an aqueous alcohol solution is filled together with a propellant in a sealed container.

であった。In conventional alcohol-based sterilizing sprays as alcohol-based aerosols, LPG, fluorocarbons, carbon dioxide gas, or the like has generally been used as the propellant (gas propellant i).

射ミストの均一性に欠けること、などの問題がある。Although LPG has the function of maintaining internal pressure, it is flammable and therefore poses a risk of catching fire, so it is not preferred. CFCs similarly have the function of maintaining internal pressure, but their release causes the problem of destruction of the ozone layer. Since carbon dioxide gas exhibits high solubility in alcohol-based contents, it exhibits a significant internal pressure-maintaining function within the aerosol pressure vessel. However, on the other hand, there are problems such as poor liquid drainage at the injection holes, resulting in dripping, and lack of uniformity in the sprayed mist.

えられる。なお、これらの現象は、アルコール濃度が低
い程顕著に現れてくる。It is thought that dripping occurs when carbon dioxide gas evaporates (degasses) from the alcohol-based contents remaining in the actuator and valve parts after spraying, and the contents are forced out of the injection hole in the form of liquid or foam. It will be done. In addition, the generation of non-uniform spray mist is caused by the carbon dioxide gas dissolved in the contents being degassed under reduced pressure at the same time as the contents are being injected. It is thought that this is caused by the formation of droplets. It should be noted that these phenomena become more pronounced as the alcohol concentration decreases.

噴射効果が消滅することとなる。When a mixed gas of inert gas and carbon dioxide gas is used as a propellant, a study of its composition ratio revealed that the amount of carbon dioxide in the gas phase inside the sealed container exceeds 90%, and the amount of inert gas accounts for 10%. If it is less than this, a phenomenon may occur in which liquid drips at the injection hole or the sprayed mist becomes non-uniform. Also,
On the other hand, if the amount of carbon dioxide in the gas phase is less than 4% and the amount of inert gas exceeds 96%, the gas phase volume will increase with use and the pressure of the inert gas will decrease significantly even though there is residual liquid. The injection effect will disappear immediately.
