Abstract
A device for packaging and dispensing a substance in the form of a liquid, a gel, or a paste, e.g. a cosmetic, comprises a reservoir and a dome-shaped applicator communicating internally with the reservoir and provided with outlet orifices, with the substance being caused to flow through the outlet orifices by being subjected to pressure upstream therefrom. The applicator includes an elastic outer membrane pierced by substance-dispensing orifices and an inner supporting wall having feed orifices that are offset from the dispensing orifices so that when the outer membrane is at rest it isolates the feed orifices from the outside, the outer membrane being capable of moving elastically away from the inner supporting wall under the effect of dispensing pressure being applied to the substance so as to enable the substance to flow out therethrough.
