Patent ID: 6974053

Claim:
A dispensing and closure system arranged at an end of a container formed by a soft tube containing a liquid or pasty product which is delivered by pressing on said tube, said system comprising a valve comprising two concentric elements, a first one of said concentric elements forming a mobile cylindrical delivery valve that includes, in its central upper part, an opening defining a peripheral seat, and a second one of said concentric elements forming a cylindrical body emanating from a plate linked to the tube, a closed top of said cylindrical body being able to interact, upon closure, with the seat of said mobile delivery valve, the two concentric elements defining between them an annular gap through which the product passes, at the time of a manual pressure exerted on the tube, causing, as a consequence, the product to act directly on the delivery valve causing the delivery valve to open, countering an elastic return member, and a double seal obtained in the opening/closure zone of the valve by means of the combination of a first peripheral lip and a second lip, which is also peripheral, produced at a distance from the first lip such that said lips form a double closure so that, upon closure, the residue of material located between the two lips is expelled outward, with no possible return of the product that has already exited toward the inside.
