ABSTRACT:
A two-piece dispenser for flexible plastic fluid-containing bags. An outer tubular sleeve has a flange attached to the sealed fluid-containing bag. The bore of the sleeve has two annular grooves, one adjacent the bag surface, the other with a semicircular cross-section and displaced within the bore from the first groove. The second piece is a coaxial barrel having sharp piercing points on a plurality of long, flexible blades, at least one of which carries a tooth extending radially from the surface for engaging the annular grooves. In the first or semicircular cross-sectioned groove, the tooth operates to strongly resist longitudinal movement of the barrel so that it cannot be accidentally removed or moved inward to pierce the bag. For dispensing, the barrel is forcibly pushed in to dislodge the tooth from the first groove, cause the blade tips to pierce the fluid-containing bag, and latch the tooth into the second groove to prevent any removal of the barrel from the sleeve.
The invention also includes a removable assembly for remote dispensing of the fluid. This assembly pierces the bag, expands a ring of small balls into the first annular groove for temporarily locking the assembly and then can be removed by retracting the balls from the annular groove.
