Dispensers for flexible sealed plastic bags used for the storage of wines or other liquids that may spoil when exposed to the air. The outer sleeve of each of the described embodiments of the dispenser is attached to the exterior surface of the sealed bag and either cuts or shears open the bag by a combination of rotational and longitudinal movement of the barrel of the dispenser within the sleeve. The fluid is thereafter dispensed through radial holes through the sleeve and the barrel by only rotational adjustment of the sleeve within the barrel.

In combination with a bulk fluid container comprising a flexible, sealed, fluid-containing bag, a fluid despenser including: a tubular sleeve having a first end surface attached to the exterior surface of the fluid-containing bag, the longitudinal axis of said sleeve being substantially perpendicular to said bag exterior surface; a tubular barrel slidably positioned within the bore of said tubular sleeve, said barrel having a first end adjacent the first end of said sleeve and said sealed bag surface, and a handle at the second end for manual rotation of said barrel within said sleeve; valving means including a radial dispensing aperture through the wall of said tubular sleeve and through the wall of said tubular barrel and adjacent the second ends of said sleeve and barrel for controlling the flow of fluid from said fluid-containing bag through the bore of said barrel by the rotation of said barrel in said sleeve; and opening means on the first end of said barrel for cutting a substantially circular opening with a diameter at least as large as that of said barrel first end in said sealed fluid-containing bag and within the area of said sleeve end surface by urging means for providing a combined rotational and inward longitudinal movement of said barrel within the bore of said sleeve for shearing said bag surface in a circular pattern between the exterior first end edge of said barrel and the interior first end edge at the bore of said sleeve.
