Abstract

A closure system suitable for sealing a growler and dispensing beer under the influence of gravity and atmospheric pressure through a conventional tap faucet. A growler sealed with the closure system is held in an inverted position by a support system. The closure system is lower than the body of the growler and is connected to a conventional tap faucet. The closure system includes a cap with a manually operated valve. The valve rotates from a closed position to an open one, which opens two channels in the cap: one to conduct beer from the growler to the tap and the other to conduct ambient air into a collapsed bladder—which is an integral part of the cap—when the tap is opened to dispense beer. The collapsible bladder expands into the growler when the beer is dispensed to take up the volume vacated by the beer. The closure system and the support can be included in a kit, alternatively each component can be packaged as a stand-alone item.

Claims31

Dependent claims

A closure system for sealing and dispensing from a growler type vessel comprising

an L-shaped dust cover;
a turn valve with a tiered cylindrical stem having an upper surface with a recess for receiving a portion of the L-shaped dust cover, and two lower stem surfaces each having different diameters and two channels contained within the cylindrical stem, a circular-shaped channel connects the top valve surface with an opening on the side of the cylinder stem and the other channel, with a half-moon shape, connects the upper surface with the second lower surface;
a cylindrical tiered cap body having an upper surface and two lower surfaces with different diameters, and a socket open to the upper surface for receiving the cylindrical stem of the turn valve, which socket permits rotation of the cylindrical stem about a longitudinal axis and which forms a fluid tight seal with the surfaces of the cylindrical stem of the turn valve and which first lower surface of the cap contains a recessed ring-shaped area for receiving and securing an opening of the growler type vessel, forming an air tight and fluid tight seal;
a hag tube, which attaches to the lower most surface of the cap body;
and
a collapsible bladder having an opening, which when deflated is gathered within the bag tube and which is connected to the lower most surface of the cap body through the opening.
