Chew toys comprising biologically degradable material
View Patent ↗A biodegradable chew toy having a first body that is made of a first biodegradable material have first characteristic. A second body is made of a second biodegradable material having a second characteristic. The second body is overmolded by the first body. The first characteristic and the second characteristic differ by elasticity.
1. A biodegradable chew toy comprising:
a first body comprising a first biodegradable material have first characteristic;
a second body comprising a second biodegradable material having a second characteristic; and
the second body being substantially overmolded by the first body;
wherein the first characteristic and the second characteristic differ by elasticity.
2. The biodegradeable chew toy of claim 1 , wherein the second body comprises a plurality of recesses on a surface of the second body to enhance retention of the first body.
3. The biodegradable chew toy of claim 1 , wherein the second body comprise a cross-sectional shape of a plus sign.
4. The biodegradable chew toy of claim 1 , wherein the second body comprises a passage through the second body to provide an anchorage for the first body.
5. The biodegradable chew toy of claim 1 , wherein the first characteristic and the second characteristic differ by texture.
6. The biodegradable chew toy of claim 1 , wherein the first biodegradable material and the second biodegradable material differ by one of color and flavor.
7. The biodegradable chew toy of claim 1 , wherein the first biodegradable material is operatively elastic and the second biodegradable material is operatively inelastic.
8. The biodegradable chew toy of claim 1 , wherein the first biodegradable or second biodegradable material comprises a starch and a binder.
9. The biodegradable chew toy of claim 8 , wherein the binder comprises ethyl vinyl acetate and casein.
10. A biodegradable chew toy comprising:
a core comprising a first biodegradable material having a first elasticity;
a cover comprising a second biodegradable material having a second elasticity; and
the cover substantially overmolding the core;
wherein the first elasticity and the second elasticity differ.
11. The biodegradable chew toy of claim 10 , wherein the core comprises a plurality of recesses on a surface of the core to enhance retention of the cover.
12. The biodegradable chew toy of claim 10 , wherein the core comprises a cross-sectional shape of plus sign.
13. The biodegradable chew toy of claim 10 , wherein the core comprises a passage through the core to provide an anchorage for the cover.
14. The biodegradable chew toy of claim 10 , wherein the core comprises an outer shape of a bone or sphere.
15. The biodegradable chew toy of claim 10 , wherein the cover comprises a layer.
16. The biodegradable chew toy of claim 10 , wherein the first and second biodegradable materials comprise thermoplastics.
17. A biodegradable chew toy comprising:
a first biodegradable material and a second biodegradable material differing from the first biodegradable material by elasticity;
the first biodegradable material comprising a first shape supportive for retaining an overmold of the second biodegradable material substantially on all of the first shape;
the first shape comprising one of a passageway through the first shape or a plurality of recesses in a surface of the first shape.
18. The biodegradable pet chew toy of claim 17 , wherein the second biodegradable material comprises a second shape different than the first shape.
19. The biodegradable pet chew toy of claim 17 , wherein the second biodegradable material comprises a second shape similar to the first shape.
