Sound-producing pet toy
View Patent ↗A pet toy makes a sound when bitten or squeezed by an animal. The toy contains a resilient shell that substantially surrounds the sound-producing material. The toy also contains a core constructed of an elastic material located beneath the sound-producing material. The sound-producing material is a plastic material such as polyethylene terephthalate, which deforms when external pressure is applied to it, creating sound and vibration. In an embodiment of the invention, air permeates the sound-producing material, the core is hollow, and acoustic ports are located at each end of the toy, all to enhance its sound generating characteristics. In another embodiment, a strand is attached to or passes through the core of the pet toy. In another embodiment, an elastic outer sleeve is attached to the sound-producing material at various location between their surfaces, to reposition the sound-producing material to its original orientation after external pressure is released.
1. A sound-producing pet toy apparatus comprising:
an elastic core having an outside surface;
a crackling member having an inside and an outside surface, the crackling member being positioned with the inside surface of the crackling member substantially adjacent to the outside surface of the elastic core; and
a resilient outer shell member substantially encircling the crackling member and the elastic core, the shell having an inside and an outside surface, the inside surface of the shell being positioned about the outside surface of the crackling member in a first configuration;
the apparatus having a second configuration in which at least a portion of the crackling member and elastic core are deformed by a force applied to the resilient outer shell, the crackling member producing at least one of a sound and a vibration upon deformation; and
upon release of the applied force, the elastic core reshapes the apparatus toward its first configuration, the crackling member again producing at least one of a sound and a vibration, as the elastic core, the crackling material and the shell substantially return to the first configuration.
2. The pet toy apparatus of claim 1 , wherein the resilient outer shell is constructed of an elastic material.
3. The pet toy apparatus of claim 2 , wherein the shell and the core are constructed of the same elastic material.
4. The pet toy apparatus of claim 1 , wherein air is disposed between the core and shell, adjacent to at least one of the inside and outside surfaces of the crackling member.
5. The pet toy apparatus of claim 1 , wherein the crackling member comprises one or more layers of a sound-producing material.
6. The pet toy apparatus of claim 5 , wherein the one or more layers of sound-producing material comprise polyethylene terephthalate (PET).
7. The pet toy apparatus of claim 5 , wherein the crackling member comprises a sheet of sound-producing material overlapping itself.
8. The pet toy apparatus of claim 5 , wherein the one or more layers of sound-producing material include textured portions.
9. The pet toy apparatus of claim 8 , in which one layer of sound-producing material overlaps another layer of sound-producing material, wherein the textured portions substantially space apart the layers of sound-producing material from each other.
10. The pet toy apparatus of claim 1 , wherein the outer shell contains at least one acoustic port.
11. The pet toy apparatus of claim 10 , wherein the core contains at least one acoustic port, the at least one acoustic port in the core being aligned with the at least one acoustic port in the shell.
12. The pet toy apparatus of claim 10 , wherein the shell includes two acoustic ports disposed at opposite ends of the shell.
13. The pet toy apparatus of claim 12 , wherein the core includes two acoustic ports disposed at opposite ends of the core, each of the acoustic ports in the core being aligned with one of the acoustic ports in the shell.
14. The pet toy apparatus of claim 13 , wherein the core includes an inside surface that extends between each of the acoustic ports at opposite ends of the core.
15. The pet toy apparatus of claim 14 , further comprising a strand operably disposed at least partially within the inside surface of the core.
16. The pet toy apparatus of claim 1 , further comprising a strand extending at least partially within the core.
17. The pet toy apparatus of claim 16 , wherein at least a portion of the strand includes one or more filaments of sound-producing material, to generate at least one of a sound and a vibration upon deformation.
18. The pet toy apparatus of claim 17 , wherein the strand is made of a polyethylene terephthalate (PET) material.
