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, if required for certain applications, located in an expandable pouch (10), or at least in a reservoir of the other component (19) of the gas generating system, with the membrane (36) facing down. The trigger (18), alone or in 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 an added fluid, such as 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). |
