ABSTRACT:
A fluid pressure opened reclosable pouring spout for a flexible container is formed by a sleeve assembly axially inserted into the exit end of the pouring spout for normally closing the latter. The sleeve assembly comprises a first sleeve bonded to the inner surface of the pouring spout of the exit end portion which contains an annular inwardly projecting flange-like wall slidably receiving a piston sleeve valve normally sealing with the outer end of the first sleeve and biased to an open position by a spring or weight when the walls of the container are manually squeezed, to apply liquid pressure against the closed end of the piston sleeve valve. The wall of the piston sleeve valve is provided, adjacent its outer end, with a circumferential row of apertures for discharging liquid when the piston sleeve valve is opening. The inward end of the piston sleeve valve is longitudinally slotted in circumferential spaced relation for inserting the sleeve valve into the wall sleeve.
