Abstract
A tap assembly for a container of liquid comprises a delivery spout molded of a gas impermeable plastic and a unitary dispenser closure molded of an elastomeric material having the required resiliency for valve operation. The spout has a neck which opens outwardly into a hemispherical bowl terminating in a rim and having an opening providing a dispensing port. The closure has a bowl-shaped diaphragmic wall which snaps onto the rim and seat in the bowl of the spout in a closed-valve position as a seal across the neck and port openings. An integral toggle projects axially forwardly from the bottom of the bowl-shaped wall for finger manipulation to distort the latter from the closed-valve position to an open valve-position of partially unseated configuration for dispensing liquid from the container. A plug, molded of a gas impermeable plastic, forms a temporary gas barrier and comprises a stopper portion sized to fit the neck of the spout and a forward extension which projects into a hollow formed in the toggle. The toggle is also depressible inwardly to dislodge the plug into the container preparatory for use. Alternatively, a flexible disk having gas impermeable properties is permanently mounted on the interior side of the bowl-shaped wall of the closure, moves therewith from closed to open valve positions, and coacts with the spout as the gas barrier when closed.
