Abstract
Abstract An animal collar made from a unitary or single piece of flexible sheet material having a plurality of compartments for containing and controllably emitting a powdered material is disclosed. The emission of the powdered material is through a plurality of pores formed in one or more walls of each compartment. The powdered material contained within the collar can be any material which is suitable for distribution on the hair and/or skin of an animal, such as an insecticidal, medicinal, animal grooming or the like composition.
