Abstract
An automatic dispensing device for volatile fluid operable to apply one or more agent to a local environment for more than 14 days. A dispensing device may nonexclusively operate by evaporation of volatile fluid from a carrier material that is somehow infused with the volatile fluid; gravity-induced drip from a bulk supply of volatile fluid through a small orifice onto an emanator; osmotic transfer of volatile fluid through the emanator from a bulk supply; gas-pump drive of volatile fluid to the emanator at controlled pressure or volume; or diffusion of volatile fluid through a wall of a container of bulk volatile fluid; and combinations thereof. An emanator of the volatile fluid is desirably biodegradable and formed from renewable materials.
Claims17
An apparatus, comprising:
