Abstract: A combined pump and tap assembly for a beverage container includes a cylinder for a hand pump and a gas tube projecting downwardly from the bottom wall of the cylinder and communicating with the interior of the latter. A hollow boss rigid with the bottom wall provides a connection for a downwardly projecting draw tube and a fitting for a dispensing hose is rigid with the boss and communicates with the draw tube through the boss. The cylinder, its bottom wall, the boss and the fitting are made as an integral unitary part so as to effectively preclude the user from disabling the hand pump and connecting the gas tube to another pressure source which may be unregulated and cause the container to explode.

Abstract: A hand-operated pump includes a cylinder and a reciprocating plunger. The plunger is made from plastic and includes a piston, a stem and an enlarged hand grip which are all molded integrally with one another so as to form a one-piece unit. The end of the cylinder is closed by a pair of separable caps which are adapted to be slipped sidewise onto the plunger and attached to the cylinder after the plunger has been assembled with the cylinder.

Abstract: The closure is an improvement over that shown in our U.S. Pat. No. 3,592,351 in that the present closure is capable of accommodating a tap with non-coaxial gas and draw tubes which make the tap effective for use in series tapping systems.
