Abstract
The device (100) for packaging and dispensing a product, liquid or in gel form, optionally for an ophthalmic application, comprises a container (1) containing the product to be dispensed by a dispensing head (7), as well as a refilling and filtering assembly for the air entering the container (1) after a dispensing, the dispensing head delimiting one or more dosing chambers (5) and including at its end a flexible part (7) which can be actuated to allow the release of the dose of product in a compressed state of said chamber (5). The air refilling and filtering assembly has a sterilizing filter (11) which cooperates with a check valve (12), this assembly (11, 12) being typically located in a central or inner portion of the head (7). The supply of outside air is accomplished by means of a channel (16) leading to an outer orifice (10) able to be obturated by a cover (15).
