Abstract
A wine or beer keg dispenser spout has a curved exterior bead terminating in an outward-downward slanted surface, then a cylindrical surface and a horizontal shoulder below the latter. A cap for the spout is of plastic having a top disk and a depending skirt which fits over and snugly engages the exterior of the spout, the lower edge of the skirt resting on the shoulder. A tab extends below the skirt at an acute angle to the bottom edge. The skirt is weakened in a score line which is an upper extension of the top edge of the tab and continues to a terminus above the bead. Pulling the tab tears the skirt along the score line to permit separation of the cap.
