Dental chew toy
The present disclosure is directed to products and methods useful for a dental chew toy capable of stimulating and/or cleaning the tooth surfaces and/or gums of a domesticated animal. The dental chew toy includes a plurality of flexible dental elements extending outward from a core member. A relatively flexible outer cover surrounds the core member and the plurality of dental elements. A plurality of apertures formed in the outer cover allow passage of the dental elements when the outer cover is compressed via chewing action of the animal. Hollow tubes may surround the dental elements to guide the dental elements through the apertures formed in the outer cover.
1. A dental chew toy, comprising:
a core member;
a plurality of dental elements extending radially outward from the core member having a first end engaged to the core member and a second end distal from the core member; and
a flexible outer cover having an outer side and an inner side, and deformable from an uncompressed state to a compressed state in response to a compressive force on the outer cover, the outer cover disposed about the core member and having a plurality of apertures formed therethrough, each of the plurality of apertures disposed proximate the second end of a respective one of the plurality of dental elements;
wherein, when in the compressed state, each of the plurality of dental elements extend outwardly from the inner side of the outer cover, through the respective aperture, to the outer side of the outer cover, and such that a portion of each of the plurality of dental elements is disposed outward of the respective aperture outward of the outer side of the outer cover.
2. The dental chew toy of claim 1 , wherein the dental elements comprise a plurality of fibers.
3. The dental chew toy of claim 1 , further comprising a plurality of hollow tubes, each of the plurality of hollow tubes disposed about a respective one of the plurality of dental elements.
4. The dental chew toy of claim 3 , wherein each of the plurality of hollow tubes comprises a hollow tube formed integral with the outer cover.
5. The dental chew toy of claim 4 , wherein, in an uncompressed state, the plurality of dental elements do not extend beyond the outer cover.
6. The dental chew toy of claim 1 , wherein the core member comprises a spherical core member having a diameter.
7. The dental chew toy of claim 6 , wherein the outer cover comprises spherical outer cover having an outer cover diameter, the outer cover diameter greater than the spherical core member diameter.
8. The dental chew toy of claim 7 , wherein the ratio of the outer cover diameter to the spherical core diameter is less than 2.0.
9. The dental chew toy of claim 1 , wherein the flexible outer cover comprises silicone elastomer, polyurethane elastomer, polyester elastomer, or natural rubber.
10. The dental chew toy of claim 1 , wherein, in an uncompressed state, each of the dental elements includes an exposed portion that extends beyond the outer cover.
11. The dental chew toy of claim 10 :
wherein each of the dental elements have a first length; and
wherein the exposed portion of each of the dental elements is 25% or less of the first length of said dental elements.
12. The dental chew toy of claim 1 , wherein said core member includes one or more apertures.
13. The dental chew of claim 12 , wherein said core member includes a one-way valve configured to introduce a formulation into said core member.
14. The dental chew of claim 12 , wherein said core member comprises two separate portions that can be releasably mechanically engaged.
15. The dental chew toy of claim 1 , wherein said core member includes one or more apertures and contains a formulation that is configured to be released upon compression of said core member.
16. The dental chew toy of claim 15 , wherein said formulation comprises a liquid.
17. The dental chew toy of claim 15 , wherein said formulation comprises a substance with a viscosity in the range of 500 centipoise to 250,000 centipoise.
