    • Method and apparatus is described for removing oxygen from a can and frothy head inducing capsule of a lightweight two piece can beverage pack storing alcoholic beverage under gaseous pressure. The method involves evacuating the can and the capsule combination and purging with an inert gas such as Nitrogen and retaining the purged condition of the capsule and of the can by filling the can with water. Just before the can is to be filled the can is inverted to pour the water away and is washed in a conventional manner and re-inverted ready for filling. The method may be automated by marshalling cans on a conveyor and purging a large number of cans simultaneously in a batch first of all to the evacuation, then the purging step and then the water filling step. Two batch purging units may be provided and operated out of synchronism to provide a continuous supply of purged cans partly filled with water ready for feeding to the can washing and filling facility. Alternative apparatus involves injecting Nitrogen gas in liquid or gaseous from into the capsule before or after it is inserted into the can and plugging the hole made by the falling device so as to retain the gas charge within the capsule.

    • Devices are described for fitting into pressurized individually packaged beverages (typically canned beers, ales and stouts), by which gas at high pressure is stored within the package for jetting into the beverage as the package is opened to atmosphere. One embodiment comprises a length of tube (10) having a gas jetting orifice (14) which in use is submerged below the beverage in a pressurized can having a gaseous headspace, which can be used to charge the tube with gas during the passage of the filled can (16) along a conventional canning line, on which the can is inverted after filling which brings the orifice into the gaseous headspace. A more preferred design of device comprises a molded plastics capsule (34; 50;78) secured near the bottom of a can (20, 88) with an internal, preferably central, pipe (56; 62; 80) to provide a liquid seal to prevent loss of gas when the can is inverted from the upright position, and an airlock when the can is upright, to prevent beverage which has entered the capsule from leaving it when the can is opened to atmosphere. A further design of capsule (96) having a central internal pipe (98) and adapted to be pressurized solely by the ingress of beverage, which is fitted midway down the can (94) but which still only jets gas on opening, is also described.
