Abstract: A dispensing package assembly useful for dispensing a predetermined amount of a fluent material comprises a relatively stiff base sheet, a blister overlay appended to the overlay and a dispenser pouch housed within the confines of the overlay and the sheet. The blister overlay having a main cavity and a secondary cavity includes a dispenser depression, preferably in the shape of a thumb indention, which protrudes downward into the main cavity. A shearing depression extending laterally through the secondary cavity defines an area of reduced depth within the secondary cavity. The main body of the pouch is located within the overlay main cavity having a dispensing channel or passageway extending therefrom beneath the shearing depression and into the secondary cavity.

Abstract: A liquid phase composition of a pyrethroid in concentrations greater than 50% w/w that may be used as a basis for other pyrethroid containing formulations in physical phases other than the liquid phase is described. A method of treatment utilizing the composition on domestic mammal is also described. The composition can be applied as a small dose to a localized region of the animal's body which is then delivered to relatively all of the animal's body surface by migration of the pyrethroid.
