Abstract: A closure on a bottle is adapted to be activated by surfaces of a cooler well to move a plunger from a closed position to a position at which water is adapted to flow out of the bottle. Selected tolerances of the plunger and sleeve in which it moves provide a seal at the closed position and prevent the plunger from being fully withdrawn from the sleeve.

Abstract: A tapping faucet for dispensing beverages, in particular beer, includes a compensator arranged in a tapping faucet housing provided with a tapping faucet outlet and being a body which is conical at one end, and a closing seal operable via an actuating device, for example, a lever. The tapping faucet is characterized in that the compensator provided with a flow-through duct for the beer is installed in the beer conduit or shaft with its conical end in the direction of the front end of the tapping faucet housing, in which for forming an annular gap for the pressure compensation and for the opening and closing of the tapping faucet, a spring-loaded sealing and adjusting bushing provided with a corresponding conical cavity is arranged. The bushing is capable of being tightly pushed by the actuating device, for example, the lever, over the conical part of the compensator in the longitudinal direction, and away from the part for forming the annular gap.

Abstract: A self-closing push-pull top for a bottle includes a threaded collar adapted to engage a threaded bottle neck. A hollow stem extends from the threaded collar and engages a cylindrical guide aperture of a cap. The cap is slidable along the hollow stem about the guide aperture to a first position in which the hollow stem and the cap are positioned with respect to one another to prevent fluid flow from the bottle. The cap is further slidable along the hollow stem about the guide aperture to a second position in which the hollow stem and the cap are positioned to allow fluid flow therethrough. A biasing member is provided for biasing the cap in the first position. Since the cap is biased in this first position, it normally remains closed. Upon application of working pressure, the biasing member deforms to allow the cap to slide to the second position in which fluid may be dispensed from the bottle.

Abstract: A nozzle for a liquid container has first and second nozzle parts. The first nozzle part has a flange for engaging a collar to secure it to a container. A sealing member abuts the flange and includes a first sealing surface rebutting a neck of a container and a second sealing surface.

The contents of the canteen may now be sucked through the tubular member.

Abstract: A valving mechanism for a balloon inflator is presented. The valving mechanism is attached to an inflator comprising a fan driven by a through-flow motor. A piston, received within a cylinder, has two bores passing therethrough, the first bore communicating with atmosphere, and the second bore communicating with a nozzle adapted for receipt of a balloon neck. When the balloon is placed on the nozzle and the piston is urged against a spring, an airstream passes through the second bore to inflate the balloon. When the balloon is removed, a spring urges the piston to a position in which the airstream passes through the first bore to atmosphere reducing the load on the motor and allowing the motor to run cooler.

Abstract: A home carbonated beverage dispenser includes a transfer valve for conducting carbonated liquid from a carbonation reservoir to an outlet spout. A characterizing feature of the device and of the valve resides in the provision of complemental arcuate guide surfaces on the relatively movable surfaces of the valve which are brought into registry in the dispensing condition of the valve, whereby fluid flow through the valve is effected with a minimum of turbulence. A restrictor orifice is formed at the port, the orifice being defined by arcuate surfaces which mate with and provide a smooth continuation with elements of the movable valve components, thereby further to minimize turbulence and assure minimal loss of carbonation.
