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.
Claims29
An animal collar for containing and emitting a powdered material, said collar being made from a single sheet of flexible material, comprising a plurality of compartments holding said powdered material, said compartments having a plurality of pores formed through at least one wall of each of said compartments, wherein said powdered material is emitted through said plurality of pores onto an animal on which said animal collar is placed.
An animal collar for containing and emitting a powdered material made from a single sheet of flexible material comprising at least one compartment holding said powdered material, said compartment or compartments having a plurality of pores formed in at least one wall of each of said compartment or compartments, said pores being formed by laser drilling, wherein said powdered material is emitted through said plurality of pores from said collar onto an animal on which said collar is placed.
A method of making an animal collar which controllably emits a powdered material contained within said collar comprising:
- (a) laser drilling at least one row of pores through a single sheet of flexible material along the longitudinal axis of said flexible material;
- (b) drawing said flexible material of step (a) along said longitudinal axis around a tube causing the parallel longitudinal edge margins of said flexible material to overlap and form a tube-like structure;
- (c) sealing said overlapping longitudinal edge margins to form a longitudinal seam in said tube-like structure;
- (d) forming a cross seal across the width of said tube-like structure having said sealed longitudinal seam;
- (e) causing a powdered material to flow into said tube-like structure subsequent to the formation of said cross seal;
- (f) alternately repeating steps (d) and (e) a plurality of times;
- and
- (g) after the formation of a plurality of said cross seals, cutting said tube-like structure across one of said cross seals to provide said animal collar.
