ABSTRACT:
A valve assembly can automatically and essentially totally release aerosol content from an aerosol container in a single burst without the use of electric power or constant manual activation. A diaphragm at least partially defines an accumulation chamber that receives aerosol chemical from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it a seal so as to unseal an outlet channel, and thereby initiate a spray of the main active chemical. The diaphragm is held in the open position while there is elevated pressure of active in the can and/or due to a latch that activates as the diaphragm moves to the dispensing position.
