Abstract
A dispenser that delivers a small but consistent and sustained amount of fluid over an extended period of time, particularly useful but not limited to dispensing pesticides when worn by cattle. The dispenser has a shell having an opening. A reservoir is disposed in the shell and is saturated with a pesticide. A wick is in fluid communication with the reservoir. The wick extends through the opening and has a greater capillary attraction or wicking ability than the reservoir, whereby during use of the dispenser the wick draws fluid from the reservoir and deposits it upon contact.

-
a shell having an attachment member adapted for attaching the dispenser to the animal, the shell defining an opening; a reservoir disposed in the shell, the reservoir comprising a porous material that contains the pesticide; and a wick having a first portion in direct contact with the porous material whereby the wick is in fluid communication with the reservoir and a second portion positioned adjacent the opening, the wick having a greater capillary attraction than the reservoir and wherein substantially all payout of the pesticide from the reservoir is delivered by wicking action of the wick and through the opening; wherein the rate of dose delivery from the wick remains substantially constant as the supply of the pesticide within the dispenser is depleted. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
