Therapeutic pet toy

Claim 2

A dental hygienic play toy for performing dental prophylaxis on the teeth of a carnivore as said toy is chewed by the carnivore, said toy comprising: an elastomeric elongated body having a longitudinal axis extending in the direction of said body's elongation, said body; defining an outer surface, a plurality of grooves extending circumferentially about said body and said longitudinal axis; formed in; said outer surface and having spaced sides, and a functional prophylaxis lip located between at least one of said sides of each groove and said toy's associated adjacent outer surface, said lip partially projecting over opening of the each groove and being sized and configured to scrape a tooth as it is inserted into and partially withdrawn from groove each as the carnivore chews said toy.

Claim 3

A toy, as claimed in claim 1, wherein said body has an inner surface defining a hollow core.

Claim 4

A toy, as claimed in claim 1, wherein one of said lips is located between each groove side and said toy's associated adjacent outer surface so that each said groove is provided with a pair of said lips, said lips of said pair being oriented so as to oppose each other.

Claim 5

A toy, as claimed in claim 3, wherein each lip as a surface which is flush with said toy's associated adjacent outer surface.

Claim 6

A toy, as claimed in claim 1, wherein said outer surface extending between adjacent grooves is convex.

Claim 7

A dental hygienic play toy for performing dental prophylaxis on the teeth of a dog or other carnivore as said toy is chewed by the carnivore, said toy comprising: an elastomeric elongated body of predetermined hardness, said body having an inner surface, an outer surface and a longitudinal axis; a plurality of grooves extending circumferentially about said body and said axis and formed in; said outer surface and having spaced sides, each said groove being sized and configured to scrape plaque and other debris from a tooth of a carnivore which is repeatedly inserted into the groove and at least partially withdrawn therefrom as the carnivore chews the toy said inner surface defining an inner hollow core lying along said axis which core enhances tooth scraping when a carnivore bites down upon the toy with a tooth located in one of said grooves by providing said toy body with the capability of resiliently bowing into the hollow core which, in turn, facilitates elongation of said groove thereby causing opposing sides of said groove to move inwardly towards each other, said groove sides thereby engaging a carnivore's tooth located in said groove to scrape the tooth's side and neck and the carnivore's gingiva surrounding the tooth's neck as the carnivore chews the toy, said body having a hardness which facilitate bowing of the body into the hollow core and elongation of said groove and a functional prophylaxis lip located between at least one of said groove sides and said toy's associated adjacent outer surface, said lip partially projecting over the opening of said groove and being sized and configured to scrape a tooth as it is inserted into and partially withdrawn from said groove as the carnivore chews said toy.

Claim 8

A dental hygienic play toy for performing dental prophylaxis on the teeth of a dog or other carnivore as said toy is chewed by the carnivore, said toy comprising: an elastomeric elongated body of predetermined hardness, said body having an inner surface, an outer surface and a longitudinal axis; a plurality of grooves extending circumferentially about said body and said axis and formed in; said outer surface and having spaced sides, each said groove being sized and configured to scrape plaque and other debris from a tooth of a carnivore which is repeatedly inserted into the groove and at least partially withdrawn therefrom as the carnivore chews the toy said inner surface defining an inner hollow core lying along said axis which core enhances tooth scraping when a carnivore bites down upon the toy with a tooth located in one of said grooves by providing said toy body with the capability of resiliently bowing into the hollow core which, in turn, facilitates elongation of said groove thereby causing opposing sides of said groove to move inwardly towards each other, said groove sides thereby engaging a carnivore's tooth located in said groove to scrape the tooth's side and neck and the carnivore's gingiva surrounding the tooth's neck as the carnivore chews the toy, said body having a hardness which facilitate bowing of the body into the hollow core and elongation of said groove and a functional prophylaxis lip located between at least one of said groove sides and said toy's associated adjacent outer surface, said lip partially projecting over the opening of said groove and being sized and configured to scrape a tooth as it is inserted into and partially withdrawn from said groove as the carnivore chews said toy.

Claim 9

A toy, as claimed in claim 6, wherein said functional prophylaxis lip is sufficiently resilient so as to bend downwardly towards the root of said groove as the tooth is being inserted into said groove, said lip also being sufficiently hard so that said lip scrapes the tooth as the tooth enters said groove and as said lip is bending downwardly.

Claim 10

A toy, as claimed in claim 6, wherein said body defines a functional prophylaxis lip between each groove side and the toy's associated adjacent outer surface.

Claim 11

A toy, as claimed in claim 6, wherein at least one of said grooves is generally V-shaped such that said groove sides form an included angle between about 60° and 100°.

Claim 12

A toy, as claimed in claim 6, wherein at least one of said grooves has a root which is rounded.

Claim 13

A toy, as claimed in claim 6, wherein at least one of said grooves is generally V-shaped such that said groove sides form an included angle of about 80°.

Claim 14

A toy, as claimed in claim 6, wherein at least one of said grooves has a depth which, when elongated, enables said lip to massage that portion of a carnivore's gingiva which surrounds the neck of a tooth having been inserted into said groove.

Claim 15

A toy, as claimed in claim 6, wherein two of said grooves are sized and configured and spaced a preselected distance from one another so as to enable dental prophylaxis of a carnivore's right and left molars simultaneously.

Claim 16

A toy, as claimed in claim 6, wherein two of said grooves are sized and configured and spaced a preselected distance from one another so as to enable scraping of a right and left premolar simultaneously.

Claim 17

A toy, as claimed in claim 6, wherein at least one of said grooves is sized and configured to clean canine teeth, said groove having one of its said groove sides substantially higher than its other said groove side.

Claim 18

A toy, as claimed in claim 6, wherein said body's thickness between the root of each groove and the inner surface defining the core is between about 1/4 and 3/8 of an inch.

Claim 19

A toy, as claimed in claim 6, wherein said body is made from an elastomeric material having a hardness between about 30 and 70 durometers.

Claim 20

A toy, as claimed in claim 6, wherein said body is injected molded natural rubber having a hardness of about 45 durometers.

Claim 21

A toy, as claimed in claim 6, wherein said hollow core is generally cylindrical.

Claim 22

A toy, as claimed in claim 6, wherein said circumferentially extending grooves are axially aligned about said axis.

Claim 23

A toy, as claimed in claim 6, further including: an oral hygiene substance provided along said functional prophylaxis lip.
