Abstract

Weldable faucet for flexible plastic containers, whose purpose is to establish a tight seal to the ambient oxygen during the long periods that are established from the filling of the container until the consumption of the product housed in the container begins, essentially characterized by being constituted by means of the functional combination of two elements, a neck fixed to the container by welding and a crane proper adaptable under pressure to said neck, said neck being provided in correspondence with one of its mouthpieces a perimeter expansion determining a flat washer, a whose external face is fixed by welding the container itself, while its internal face in diametrically opposite areas thereof, a membrane is fixed by a weld, constituted in a similar material, constituting the container itself, and therefore sealed at the passage of the oxygen, membrane of flexible nature to allow its deformation by the pres ion of the liquid itself during the filling of the container, and later retrieve it with perfect adaptation to the internal face of the washer establishing the intended hermetic seal, while the actual tap, provided with the corresponding plug and valve seat in the outlet, configures an extreme and internal appendage capable of punching, by axial displacement, said membrane, causing the rupture thereof at the beginning of consumption of the product housed in the container, in the first operation of the tap.
