Dispenser

摘要

A dispenser that delivers a small but consistent and sustained amount of liquid 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 holds a pesticide or other liquid. A wick is in fluid communication with the reservoir. An end of the wick is positioned adjacent 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 on the animal upon contact.
