The present invention is directed to a dip tube and valve with a quick-disconnect coupling for use in combination with a collapsible bag to dispense a liquid product therefrom. The dip tube is extruded or otherwise formed from plastic or other suitable materials and includes at least one channel in the peripheral surface thereof extending along the entire length of the dip tube. As a vacuum or suction is applied to the dip tube by a pump, initially all of the air within the collapsible bag is extracted therefrom. Subsequently, the liquid product is dispensed out of the collapsible bag and the bag collapses around a portion of the dip tube which is no longer surrounded by the liquid product. Progressively, as the liquid product is removed, the bag will continue to collapse around the dip tube, and the liquid product will continue to flow through the longitudinal channel of the tube until the contents of the collapsible bag are exhausted. The collapsible bag has a fitment or spout to which a valve with a quick-disconnect coupling is connected. The dip tube may be mounted in either the bag fitment or the valve. The quick-disconnect coupling of the valve is adapted to receive a mating coupling from the hose socket of a dispensing hose. When the respective couplings are engaged the valve is biased in an open position. The valve is normally biased to a closed position when the couplings are not engaged.

In a system for dispensing syrup from a container, said container including a fitment for defining an opening through which said syrup passes, the improvement comprising: a first coupling member having first and second open ends connected by a central bore, said second open end being connected to said fitment; a first self-sealing valve disposed in said central bore including means in said bore defining a valve seat, a valve member movable into or out of sealing engagement with said valve seat, spring means for normally biasing said valve member into sealing engagement with said valve seat, and a first actuating stem coupled to said valve member and extending toward said first open end of said first coupling member; a second actuating stem rigidly affixed in said bore inboard of the walls thereof adjacent said first actuating stem and extending toward said first open end of said first coupling member, said second actuating stem being supported at the center of a plurality of radial spokes extending from and affixed to said bore walls, said radial spokes defining fluid flow openings therebetween, said second actuating stem having a channel therethrough for guiding and supporting said first actuating stem; and a second coupling member for engaging said first open end of said first coupling member, said second coupling member including means for engaging said first actuating stem to move said valve member out of engagement with said valve seat when said first and second coupling members are fully engaged and a second self-sealing valve which is opened by said second actuating stem when said first and second couplings are fully engaged.
