Abstract:
An animal actuated applicator suitable for applying a fluid to an animal, the applicator comprising:a base plate which is in use displaced when the animal steps thereon; a dispenser adapted for dispensing the fluid, at least one pressure lever operatively associated with the base plate and arranged to be displaced in response to the displacement of the base plate, the degree of displacement being proportional to the animal's weight transferred to the base plate; and an actuating member including an actuator for actuating the dispenser in response to displacement of the pressure lever to dispense a volume of fluid which is proportional to the animal's weight transferred to the base plate; and a first abutting member provided on the base plate, the first abutting member bearing on the pressure lever when the base plate is displaced; wherein the actuating member has a sensitivity to the relative weight of different animals, the sensitivity having a finite range bordered by a predetermined minimum limit and maximum limit.
