Abstract

A gas cartridge for a liquid dispensing device using a propellant gas to dispense a liquid from a liquid container is disclosed. The gas cartridge comprises a substantially cylindrical gas container for storing said propellant gas at a high pressure and a coupling means for coupling the gas cartridge to said liquid dispensing device. The gas container comprises at least one continuous indentation formed on the lateral surface of the gas container and extending from one end of the gas container to the other end thereof. The lateral surface of the gas container is surrounded by an envelope thereby at least one fluid channel is defined along the at least one indentation, said at least one fluid channel having a first opening adjacent to one end of the gas container and a second opening adjacent to the other end of the gas container.

Abstract

The dispensing unit for a liquid container comprises an enclosure (21), an operating lever (22) externally coupled to the enclosure and movable between a closing position and an opening position and provided with a resilient member to return said operating lever from its opening position into its closing position, a dispensing spout (23) projecting from the enclosure, first and second liquid dispensing channels (24, 25) formed within the enclosure and the dispensing spout, respectively. The resilient member is a leaf spring (35) formed integrally with the operating lever and arranged to bear against the external surface of said enclosure.

Abstract

The dispensing head for liquid containers, in particular for beverage bottles, comprises a head (12) adapted for connecting to a liquid container (11), an operating member (14) movable between an idle position and a discharging position, a valve assembly operatively connected to the operating member, a discharging channel openable and closable by means of the valve assembly, and a discharging tube (16). The dispensing head further comprises a safety member (20) for indicating the unopened state of the liquid container, said safety member being arranged between the operating member and the head, and being secured to at least the operating member through a joint that can be separated only by deterioration, and further being formed as a flat and substantially undeformable piece.
