A fluid-dispenser for a bulk container for potable liquids such as wine comprises a tubular filling and dispensing gland 42 welded around a hole in a laminated plastic bag 24, a sealing cylinder 56 having a diaphragm 58 at an oblique angle that seals its inner end and a tubular dispensing member 66 with a sharp cutting edge 74 at a corresponding oblique angle. When the fluid is to be dispensed, rotation of the dispensing member will cut around most of the periphery of the diaphragm to permit the fluid to enter the dispensing member. A tongue 34 which engages the container prevents unwanted rotation. In a second embodiment the dispensing member is an unvalved rotatable tube (Fig. 7) with the cutting edge at one end and a hose or tubing connector at the second end for remote dispensing. In a third embodiment (Figs. 8-13) means (142) are provided for rotating the diaphragm cutting edge and also a double valving arrangement (166, 168, Fig. 9) and (162, 164, Fig. 11) that permits removal of the tap without loss of fluid from either the tap or from a flow of a partially filled fluid bag. <IMAGE> |
