Abstract: Disclosed is a an improved dispensing system which allows nitrogenized liquids to be dispensed from a relatively low pressure dispensing system (i.e., one operating in a relatively low pressure range). To accomplish this, the improved dispensing system includes holes having very small cross-sectional areas. The improved dispensing system may be formed so as to facilitate the manufacturability of the holes required for the proper dispensing of nitrogenized liquids. For this purpose, the improved dispensing system may include a dispensing valve body and an insert member having a plurality of grooves therein. When the insert member is inserted within the valve body, the insert member grooves, along with a portion or portions of the valve body, together form the plurality of holes required for the proper dispensing of nitrogenized liquids.

Abstract: Disclosed is a pressure generation system for a container which includes a pressure pouch having a plurality of compartments containing reactive components of an at least two component gas generation system. The compartments are separated by frangible wall portions which fail or tear in response to increasing volume of an adjacent compartment. The frangible wall portions may each comprise a continuous, integral section of frangible material. The frangible wall portions may all be formed from a single sheet of frangible material or, they may alternatively be formed from a plurality of individual sheets.

Abstract: A trigger (18), containing one component (28) of a two component gas generating system and having a headspace (37), is closed by a pressure rupturable membrane (36) and located in an expandable pouch (10), in a reservoir of the other component (19) of the gas generating system, with the membrane (36) facing down. The pouch (10) is inserted into a dispensing container (44) for flowable product, and the container is sealed. Thereafter, the trigger (18) is activated by externally pressurizing the container by back flow of fluid through a dispensing valve (46), either by adding a gas or by adding flowable product, causing the membrane (36) to rupture and the trigger (18) to discharge its contents into the reservoir of the other gas generating chemical (19).
