Animal chew with cylindrical portion
View Patent ↗The present invention provides a method for removing plaque from the exterior surfaces of an animal's teeth. An edible animal chew is supplied of unitary construction. The chew may comprise a molded body having a cylinder portion and a length on a common axial centerline, the cylinder portion comprising a curved surface and a planar surface and carrying a plurality of projections extending from the curved surface. The plurality of projections may extend radially from the curved surface and substantially perpendicular to the common axial centerline. Upon chewing by the animal on the cylinder portion of the animal chew containing the projections on the curved surface, the chew provides therapeutic action regardless of the radial direction in which the cylinder portion may be configured.
1. A method for removing plaque from the exterior surfaces of an animal's teeth comprising:
supplying an edible animal chew of unitary construction from a melt conversion process comprising a molded body having a cylinder portion and a bulbous portion including a series of knobs and depressions separated by a length portion on a common axial centerline, said cylinder portion comprising a curved surface and a planar surface and carrying a plurality of projections extending from said curved surface,
wherein said plurality of projections extend radially from said curved surface and substantially perpendicular to said common axial centerline of said animal chew and wherein said projections have a height in the range of 0.0313-1.0 inch and have an angle of intersection with said curved surface of about 80-110 degrees over the entirety of said curved surface,
said length portion including said bulbous portion maintaining a portion of said chew for the animal or owner to grasp without interference from said projections,
wherein upon chewing by said animal on said cylinder portion of said animal chew containing said projections on said curved surface provides therapeutic action regardless of the radial direction in which said cylinder portion may be configured during chewing.
2. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein said cylinder portion further comprises a plurality of ribs extending from said planar surface.
3. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 2 wherein said ribs extend substantially perpendicular to said planar surface and are arranged in a parallel configuration.
4. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 2 wherein said ribs and projections are sized to locate between and contact between the animal's teeth when chewed include a portion of ribs or projections sized to locate between and contact between the front incisors, canines and molars of said animal.
5. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 2 wherein said ribs are greater than 0.0313 inches.
6. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein said projections comprise a top section and a base section, said base section attached to said curved surface wherein said top section is a configuration selected from the group consisting of hemispheric, conical, prism, pyramidal and combinations or truncations thereof.
7. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein said knobs are assorted sizes.
8. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein the edible animal chew comprises a resin, wherein said resin is selected from the group consisting of starch, casein, denatured and partially hydrolyzed collagen and mixtures thereof.
9. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 8 wherein said starch comprises wheat starch.
10. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 8 wherein said starch comprises wheat starch.
11. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein said edible chew comprises a humectant.
12. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein said edible chew comprises an attractant.
13. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein said edible chew comprises vitamins.
14. The method for removing plaque from the exterior surfaces of an animal's teeth of claim 1 wherein said edible chew comprises flavorings.
15. The method of claim 1 wherein said plurality of projections that extend radially from said curved surface are present and extend about substantially the entirety of the curved surface.
16. The method of claim 15 wherein said cylinder portion has a length, and said plurality of projections which extend about the entirety of the curved surface extend substantially along the entirety of said cylinder portion length and define substantially parallel lines along said length.
