Benefits of technology

The aerosol product described in this patent has a unique design that allows the contents of the spray, such as a liquid and vaporized gas, to mix together inside the nozzle. This results in a spray that is not too cold and can be easily absorbed by the skin. The design also allows for the inclusion of different types of valves, optimizing the application of liquids. The container is simple to hold and the nozzle design ensures an even spray. This technology offers a more efficient and comfortable spray experience.

Problems solved by technology

However, the type and amount of the liquefied gas are restricted by the properties and affinities of contents, and the amount of ejected content varies depending on the purpose of use.
A configuration that creates an optimal mist was thus not necessarily achievable.

Abstract

To provide a simple-structured aerosol product with few limitations on applicable liquids and capable of spraying a mist of fine particles without giving too much sensation of coldness. The aerosol container (101) includes a plurality of holding spaces by being partitioned and a plurality of valves (110) corresponding to the holding spaces. At least one of the plurality of holding spaces is a liquefied gas containing section (131) that holds a liquefied gas LG, and at least one of the plurality of valves (110) is a gas phase valve (110A) that ejects vaporized gas from the liquefied gas containing section (131).

Description

TECHNICAL FIELD[0001]The present invention relates to an aerosol product having a valve with a stem protruding from an aerosol container, and a nozzle that fits with the stem, and more particularly to an aerosol product that favorably sprays a mist of the content therein.BACKGROUND ART[0002]Aerosol products having a valve with a stem protruding from an aerosol container, and a nozzle that fits with the stem, are well known, and so are products that spray a mist of the contents in the container from the nozzle.[0003]The content is atomized as it is ejected from the outlet orifice. For spraying the mist of the content, generally, the amount of ejected content, the ejection pressure, and the nozzle outlet shape are designed suitably in accordance with the properties of the content so as to produce a favorable spray of mist by the expansion force of the liquefied gas near the outlet orifice.[0004]The ejection pressure of the content and the expansion force of the liquefied gas near the ...
