초록 ▼

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.

대표청구항 ▼

A liquid dispensing device containing a supply of scent-producing liquid stored in a liquid reservoir, which maintains said scent-producing liquid supply in isolation from the ambient atmosphere, whereby during functional operation, an absorbent wick, forming part of a wick assembly makes contact with said scent-producing liquid whereby said wick conveys by capillary action said scent-producing liquid at a slow substantially constant rate to the opposite end of said wick which is in physical contact with an evaporative surface of an emanator remote from said liquid reservoir, wherein said emanator diffuses said scent-producing liquid into the ambient atmosphere by the process of evaporation wherein: A. said liquid reservoir comprises a generally planar bag formed by the peripheral union of two wall members, said wall members being comprised of impermeable flexible polymeric film material and being sealed together in a continuous manner along their edgewise periphery providing a liquid-tight peripheral seal, wherein a passageway extends through said peripheral seal to accommodate the protrusion of said wick assembly between said wall members, wherein a liquid-tight seal is additionally maintained between said periphery seal and said wick assembly; B. said wick assembly extending in a continuous manner from said evaporative surface of said emanator protruding through said liquid reservoir container and making physical contact with said scent-producing liquid during functional operation, and wherein said wick assembly comprises said absorbent wick laterally enclosed within a hollow impermeable tubular element, wherein said tubular element is open at each end allowing a portion of said wick to extend beyond said tubular element at each end, and wherein said wick makes physical contact with said evaporative surface of said emanator at one end and during functional operation said wick on the other end makes physical contact with said scent-producing liquid in said liquid reservoir; C. said emanator comprising an absorbent material capable of absorbing said scent-producing liquid into the ambient atmosphere by the process of evaporation; D. said scent-producing liquid being maintained isolated from said wick prior to functional operation by means of a containment member, whereby upon removal of said containment member said scent-producing liquid is free to contact said wick thus, commencing the functional operation of said liquid dispensing device.
