Patent number: 5118015Abstract: A container of draft beer is substantially filled with beer having a volume of dissolved carbon dioxide greater than 2.6 and not more than 3.1 times the volume of beer. The beer is packaged in a plastic container that is slightly permeable to carbon dioxide, but retains a satisfactory dissolved carbon dioxide content even after a normal shelf life. Beer is dispensed by gravity, without use of external pressure source, after release of head space pressure. Moreover, when the container contents are partially dispensed by the consumer and then maintained at appropriate low temperature for several days, the remaining beer still retains a satisfactory volume of dissolved carbon dioxide. A spigot on the container employs a barrel valve closure member that seals the pressurized container and is movable to a pressure release position in which pressurized gas within the container is slowly released without forcibly projecting container contents.Type: GrantFiled: October 5, 1989Date of Patent: June 2, 1992Assignee: Scholle CorporationInventors: William R.

Patent number: 5095962Abstract: The fluid dispensing device includes a tubular spout attachable to a fluid-containing vessel, such as a bag, the spout including an outer end portion of a first lateral dimension and an inner portion of a smaller lateral dimension. A valve member is slidable in the spout, the valve member being tubular and having an open outer end adapted to receive a fluid-transmitting probe and a closed inner end. The valve member has openings through its sidewall. The outer end portion of the valve member is laterally outwardly deflectable and includes localized protrusions adapted to enter the recess of a probe. In the closed position of the valve member, opposed shoulders of the valve member and of the spout resist axial movement of the valve member in either direction, and interengaged sealing surfaces block fluid flow to the openings. The outwardly deflectable portion of the valve member can be deflected as the probe enters, and the protrusions thereafter spring inwardly into the recess of the probe.Type: GrantFiled: August 9, 1990Date of Patent: March 17, 1992Assignee: Scholle CorporationInventors: William T.
