Push Opened Valve For Dispensing Liquids
US Patent:
5560522, Oct 1, 1996
Filed:
Apr 25, 1995
Appl. No.:
8/429268
Inventors:
Robert D. Clark - Norman OK
International Classification:
B65D 572
US Classification:
2224815
Abstract:
A fluid dispensing valve for a liquid container having a pouring spout is formed by an inner sleeve axially connected to the spout of a liquid container. The other end of the inner sleeve is closed and provided with wall outlet ports. An outer sleeve slidably surrounds the closed end portion of the inner sleeve for covering and uncovering the inner sleeve wall ports. The outwardly flared end of a funnel-type tube secured to the periphery of the outer sleeve projects beyond the closed end of the inner sleeve for entering a port of a receiving vessel at its other end portion. The valve is opened by axial force applied to the inner sleeve opposite its closed end which moves relative to the outer sleeve and uncovers the wall ports. Releasing the axial pressure on the inner sleeve allows a spring interposed between a shoulder or the inner sleeve and adjacent end of the outer sleeve to bias the latter toward and cover the inner sleeve ports.
Liquid Pressure Opened Pouring Spout
US Patent:
5090600, Feb 25, 1992
Filed:
Jul 9, 1991
Appl. No.:
7/728827
Inventors:
Robert D. Clark - Norman OK
International Classification:
B65D 2540
US Classification:
222492
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.
