Abstract

A multilayer pet toy has an inner structure having an inner-structure resilient material; an outer structure joined to the inner structure, the outer structure having a first layer having a first sandwich structure, the first sandwich structure having an outer-structure resilient material and a non-resilient material. Therein, the inner structure resilient material includes a first rubber compound that has a percentage of 30% or less by weight of natural rubber and a remainder being filler. The outer-structure resilient material includes a second rubber compound that has a percentage of 44% or more by weight of natural rubber and a remainder being filler.

Claims

1. A multilayer pet toy comprising:

an inner structure and an outer structure;

a layer of adhesive joining the outer structure to the inner structure;

the inner structure comprising an inner-structure resilient material; and

the outer structure comprising a first layer having an outer-structure resilient material.

2. The multilayer pet toy of claim 1, wherein the inner structure resilient material comprises a first vulcanized material and the outer structure resilient material comprises a second vulcanized material.

3. The multilayer pet toy of claim 1, wherein the inner structure resilient material comprises a first rubber compound that has a percentage of 30% or less by weight of natural rubber and a remainder being filler.

4. The multilayer pet toy of claim 3, wherein the outer-structure resilient material comprises a second rubber compound that has a percentage of 44% or more by weight of natural rubber and a remainder being filler.

5. The multilayer pet toy of claim 1, wherein the inner structure resilient material consists of a first rubber compound that has a percentage of 30% by weight of natural rubber and a remainder being filler.

6. The multilayer pet toy of claim 5, wherein the outer-structure resilient material consists of a second rubber compound that has a percentage of 44% by weight of natural rubber and a remainder being filler.

7. The multilayer pet toy of claim 1, wherein the non-resilient material comprises a textile.

8. The multilayer pet toy of claim 1, wherein the outer structure comprises a first sandwich structure, the first sandwich structure comprising the outer layer resilient material and a non-resilient material.

9. The multilayer pet toy of claim 8, wherein the inner structure comprises a first part and a second part, the two parts being separately molded.

10. The multilayer pet toy of claim 1, further comprising a squeaker.

11. A method of making a multilayer pet toy, the multi layer pet toy comprising

an inner structure and an outer structure;

a layer of adhesive joining the outer structure to the inner structure;

the inner structure comprising an inner-structure resilient material; and

the outer structure comprising a first layer having an outer-structure resilient material;

the method comprising

(a) forming a first part and a second part of the inner structure by molding;

(b) joining the first and second parts by gluing;

(c) applying an adhesive layer to the inner structure and joining at least one segment of the first layer to the inner structure to form an outer structure.

12. The method of claim 11, wherein after step (b), a step of vulcanizing the joined first and second parts to form an inner structure is performed.

13. The method of claim 12, wherein after step (c), a step vulcanizing the outer structure to form the multilayer pet toy is performed.

14. The method of claim 11, wherein step (c) further comprises applying an adhesive layer joining at least one segment of a second layer to form an outer structure.

15. The method of claim 11, wherein step (b) is performed along a peripheral edge of each of the parts.

16. The method of claim 11, wherein the inner structure resilient material comprises a first rubber compound that has a percentage of 30% or less by weight of natural rubber and a remainder being filler.

17. The method of claim 16, wherein the outer-structure resilient material comprises a second rubber compound that has a percentage of 44% or more by weight of natural rubber and a remainder being filler.

18. The method of claim 11, wherein the inner structure resilient material consists of a first rubber compound that has a percentage of 30% by weight of natural rubber and a remainder being filler.

19. The method of claim 18, wherein the outer-structure resilient material consists of a second rubber compound that has a percentage of 44% by weight of natural rubber and a remainder being filler.

20. The method of claim 11, wherein vulcanization is performed at a temperature no greater than 160 degrees centigrade.
