Abstract
A device for applying and packaging a substance in the form of a liquid or a paste, such as a cosmetic, comprises a reservoir and a dome-shaped applicator communicating internally with the reservoir and provided with outlet orifices for the substance to be dispensed. The applicator comprises an inner wall of rigid or semi-rigid plastic material fixed to the reservoir, and pierced by feed orifices, an outer membrane supported by the inner wall and having dispensing orifices in alignment with the feed orifices, but of smaller substance-passing section; and also internal closure studs for closing the dispensing orifices and located with clearance inside the feed orifices, the membrane also being capable of moving resiliently away from the closure studs under the effect of dispensing pressure in the substance so as to enable the substance to be move out from the applicator.
