Abstract: A mixing and dispensing apparatus has a small bottle which is positioned within a larger bottle. The small bottle contains a concentrated solution, and the larger bottle contains water. The small bottle has a nozzle that is off-center, a grip base that is an integral part of the bottle, and a vent to maintain zero atmospheric pressure internally. The small bottle is inverted and placed within the neck of the large bottle. The small bottle is then rotated so that the neck of the nozzle comes between two arms of a release mechanism which is an integral part of the large bottle. In an alternative preferred embodiment, the nozzle is centered, and is pushed through the arms of the release mechanism. Once the apparatus is ready for use, the small bottle is pulled upward using the base grip or a pull ring, thereby opening the nozzle and releasing the contents of the small bottle into the large bottle.

The retainer has an upwardly extending plug and is adapted to be inserted into an inner surface of the through-conduit. A dispensing valve body is bounded by an exterior surface, an interior surface, a valve perimeter, and a dispensing orifice perimeter. The dispensing valve body is shaped to fit within the through-conduit such that the valve perimeter forms a sealing relationship with the inner surface, and the dispensing orifice perimeter fits securely around and seals against the upwardly extending plug.

Abstract: A valve assembly can automatically dispense aerosol content from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives gas propellant from a portion of 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 burst of the main active chemical. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure.
