Abstract:
1. An intermittent aerosol dispensing device, for application of a product to skin of a human being, comprising an intermittent injection mechanism located downstream of an aerosol valve ( 11 ) of an aerosol dispenser, said intermittent mechanism being responsive to a pushbutton (P) of the aerosol dispensing device, wherein said intermittent aerosol dispensing device comprises a pressure chamber; said pressure chamber is configured to be airtight relative to an environment positioned outside of said pressure chamber when the aerosol valve is in a closed state, and said pressure chamber is configured to receive a flow of content into said pressure chamber when the aerosol valve is opened; whereby said pressure chamber communicates with air of said environment due to a difference between a pressure of said flow of content into said pressure chamber and an air pressure of said environment, causing said content to be dispensed; after dispensing of said content, pressure in said pressure chamber drops, causing dispensing to stop; and after said stoppage of dispensing, pressure in said pressure chamber recovers, causing dispensing of content to resume; and wherein the product contains 0.1% to 5% by weight of a compressed gas in an aerosol composition; and a ratio of an injection time to a stop time is set, in said intermittent mechanism, to 0.1 to 5.0, when said aerosol valve is opened, in order to obtain a cooling and/or massage effect on the skin, and a cycle of injection and stop is performed 1 to 25 times per second.
