Abstract
A method and apparatus are disclosed for delayed release of additional ingredients including additional propellant within a pressurized dispensing container. A reserve container within the primary product container is constructed to open or rupture as a result of a predetermined degree of depressurization of the primary container to release its contents and repressurize the primary container to enable subsequent ejection of product. A catalytic activation system is disclosed as one possible application of this invention.
