<p>The one-way valve for a container supplying a liquid under pressure by means of compression of the container is designed to be inserted between the outlet mouth (12) of the container (10) and the end (17) of the supply nozzle (14) connected thereto. Said valve comprises a hollow body (18) inserted partially into the outlet mouth (12) of the container (10), the base of which engaging with said end (17) of the nozzle (14) is open, while the other base (22) has an essentially central hole (24) through which the liquid passes. Said hollow body (18) accomodates internally an obturator member (26) essentially consisting of a shaped stopper (28) connected, via elastically deformable lugs (34), to its support element (32) inserted inside the hollow body (18) and having a longitudinal passage (40) with a cross-section greater than that of the stopper (28). The lugs (34) are designed to keep the stopper (28) engaged in the hole (24) of the hollow body (18) when the container (10) is not compressed and to allow it to be moved away from said hole (24) when the container (10) is compressed in order to supply the liquid.</p> |
