ABSTRACT:
A liquid dispensing device capable of dispensing an active liquid at a slow substantially constant rate over an extended period of time. The liquid dispenser consists of a sealed flexible bag or pouch containing a supply of the active liquid, a wick located inside a tubular member, and an emanator which diffuses the active liquid. The active liquid supply inside the impermeable bag is kept isolated from the wick prior to use by means of a containment element. Upon removal of the containment member, the active liquid is free to contact the wick, whereby the enclosed tubular wick conveys the active liquid to the emanator for slow dispersion. The sealed reservoir bag gradually collapses inward as the active liquid supply is depleted, obviating the need for a vent. The liquid dispensing device could be used as an air freshener, diffusing a volatile scent-producing liquid into the atmosphere. The device could also be adapted to dispense pharmaceuticals transdermally. In another modification, the device could be used to dispense vegetative nutrients to cultivated soil or into the water of hydroponic vegetation.
