<p>The packaging and applicator for a liquid or paste cosmetic comprises a reservoir (2) containing the product. The reservoir can be pressurised for distributing the product through a dome shaped applicator (3). The dome has a rigid plastic internal wall (7) and is fixed to the reservoir and passed through by supply holes (10). An external membrane (8) supported by the dome internal wall has distribution holes (11) aligned with the supply holes. These distribution holes have a smaller cross section for the passage of the product. The applicator also has internal sealing teeth (12) for the distribution holes which are located with play inside the supply holes. These teeth seal, in the absence of pressure, the distribution holes. The membrane can spread elastically from the sealing teeth under the effect of the distribution pressure in order to allow outlet of the product from the applicator.</p> |
