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.

A system for dispensing liquid medicine to an infant includes a baby bottle having a threaded neck portion at an upper end thereof and a rim that defines an opening; a resilient nipple member; and a ring member for holding the nipple member tightly against the rim during feedings. The ring member has threads defined in an interior portion thereof that mate with the threaded neck portion, whereby the ring member may be screwed onto the bottle. A medicine cup that includes a concave cup-like portion is sized to fit within the threaded neck portion of the baby bottle. The medicine cup further includes a flange for supporting the medicine cup on the rim of the baby bottle which is sized so as not to interfere with said ring member during screwing and unscrewing of the ring member onto the baby bottle. The cup-like portion is constructed so as to be impervious to fluid transfer therethrough, so medicine will not leak from the medicine cup into the baby bottle. Also disclosed is a method of dispensing medicament to an infant by filling the medicine cup with medicine, setting the medicine cup into the threaded neck portion of the baby bottle, and screwing the ring member, together with the nipple member, onto the threaded neck portion so as to seal said nipple member into communication with said medicine cup and out of communication with the rest of said baby bottle.
