  • Patent number: 6926172
    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.

  • Publication number: 20030106912
    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 aerosol content from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves axially, carrying with it a leg so as to unseal an outlet, and thereby initiate a spray burst. A pawl extends from the diaphragm, and engages a retention surface to resist movement of the diaphragm and prolong the accumulation phase. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure.

  • Publication number: 20030080141
    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 aerosol content 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 leg so as to unseal a valve stem, and thereby initiate a spray burst. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure. A barrier prevents the aerosol container from resupplying the accumulation chamber at a high rate during the spray phase, preferably due to a textured interface between the barrier and a passageway in which it is housed.

  • Patent number: 5542922
    Abstract: 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.

  • Patent number: RE43349
    Abstract: An apparatus for drying and storing an article, such as a baby bottle, after washing and rinsing includes a tray having a bottom face that is adapted to be supported by an underlying surface such as a counter-top, and an upper face. A plurality of pegs extend out from the upper face, and each peg is sized and arranged so as to be able to support an article, such as a baby bottle, after washing and rinsing. Each peg is mounted to the tray in such a manner as to be movable between a first storage position, wherein the entire peg is positioned relatively close to the upper face for storage and packaging, and a second, operative position. This permits the apparatus to be conveniently folded for packaging and storage purposes. Another aspect of the apparatus involves disk holding structure, connected to the upper face of the tray, for holding baby bottle disks in a location that is isolated from areas of the tray in which liquid may collect.
