Patent

CA 2148227

A trigger containing one component of a two component gas generating system and having a headspace is closed by a pressure rupturable membrane and, if required for certain applications, located in an expandable component of the gas generating system, with the membrane facing down. The trigger alone or in pouch is inserted into a dispensing container for flowable product, and the container is sealed. Thereafter, the trigger is activated by externally pressurizing the container by an added fluid, such as by back flow of fluid through a dispensing valve, either by adding a gas or by adding flowable product, causing the membrane to rupture and the trigger to discharge its contents into the reservoir of the other gas generating chemical.
