Tennis ball toy with multiple sound features
A pet toy includes an inner layer or shell; an outer layer or shell; a noise producing center layer and a noise making element. When the outer shell is deflected or compressed by contact, the center layer is also deflected thereby producing a first sound. The noise making may be a squeaker supported within an interior chamber of the toy. When the outer shell is deflected or compressed by contact, the squeaker produces a second different sound.
1. A pet toy comprising:
a thermoplastic molded outer shell defining an interior chamber;
a thermoplastic molded inner shell disposed within said outer shell, said inner shell encompassing at least an upper half of the pet toy;
a polyethylene molded center layer disposed between the inner and outer shells, the center layer producing sound when the center layer is displaced in response to deformation of the outer shell;
a noise making device having a first end supported by said outer shell, and a second end extending within the interior chamber;
wherein said central layer includes a plurality of tiers and grooves located between said tiers and said inner shell includes a plurality of annular protrusions; and wherein a plurality of curved shaped gaps is maintained between said central layer and said inner shell and the grooves of said central layer align and abut respective annular protrusions of said inner shell.
2. A pet toy, as claimed in claim 1 , wherein:
said outer shell is molded in respective half sections and joined to assemble said pet toy.
3. A pet toy, as claimed in claim 1 , wherein:
said inner shell is molded in respective half sections and joined to one another.
4. A pet toy, as claimed in claim 1 , wherein:
said center layer is molded in respective half sections and joined to one another.
5. A pet toy, as claimed in claim 1 , wherein:
said outer shell, said inner shell, or said center layer are molded in respective half sections that are each substantially symmetrical about an axis.
6. A pet toy, as claimed in claim 1 , wherein:
one half section of said outer shell includes a peripheral flange projecting radially inward; and
another half section said inner shell includes an undercut that receives said peripheral flange of said outer shell.
7. A pet toy, as claimed in claim 6 , wherein:
said center layer has an edge that is positioned between said outer shell and said inner shell adjacent said flange and said undercut.
8. A pet toy, as claimed in claim 1 , wherein material of the outer shell as a different rigidity or flexibility as compared to the material of the inner shell.
9. A pet toy, as claimed in claim 1 , wherein the inner and outer shells have different thicknesses.
10. A pet toy, as claimed in claim 1 , wherein the inner and outer shells each include a vent opening to allow air to pass into and out from said interior chamber.
11. A pet toy, as claimed in claim 1 , wherein:
said outer shell and said inner shell are elastomeric so that said outer and inner shells elastically deform in response to pressure applied and said inner and outer shells then spring back to original un-deformed shapes.
12. A pet toy, as claimed in claim 1 , further including:
a fabric cover placed over and in contact with said outer shell.
13. A pet toy comprising:
a thermoplastic molded outer shell defining an interior chamber;
a thermoplastic molded inner shell disposed within said outer shell, said inner shell encompassing at least an upper half of the pet toy;
a polyethylene molded center layer disposed between the inner and outer shells, the center layer producing a first sound when the center layer is displaced in response to deformation of the outer shell;
a noise making device having a first end supported by said outer shell, and a second end extending within the interior chamber, said noise making device producing a second different sound when the outer shell is deformed;
a fabric cover placed over and in contact with said outer shell;
wherein said central layer includes a plurality of tiers and grooves located between said tiers and said inner shell includes a plurality of annular protrusions; and wherein a plurality of curved shaped gaps is maintained between said central layer and said inner shell and the grooves of said central layer align and abut respective annular protrusions of said inner shell.
14. A pet toy, as claimed in claim 13 , wherein:
said inner shell is molded in respective half sections and joined to one another.
15. A pet toy, as claimed in claim 13 , wherein:
said outer shell, said inner shell, or said center layer are molded in respective half sections that are each substantially symmetrical about an axis.
16. A pet toy, as claimed in claim 13 , wherein:
said center layer is molded in respective half sections and joined to one another.
17. A pet toy, as claimed in claim 13 , wherein:
one half section of an outer shell includes a peripheral flange projecting radially inward; and
one half section of a corresponding inner shell includes an undercut that receives said flange of said outer shell.
18. A pet toy, as claimed in claim 17 , wherein:
said center layer has an edge that is positioned between said outer shell and said inner shell adjacent said flange and said undercut.
19. A pet toy, as claimed in claim 13 , wherein material of the outer shell has a different rigidity or flexibility as compared to the material of the inner shell.
20. A pet toy, as claimed in claim 13 , wherein the inner and outer shells have different thicknesses.
21. A pet toy, as claimed in claim 13 , wherein the inner and outer shells each include a vent opening to allow air to pass into and out from said interior chamber.
22. A pet toy, as claimed in claim 13 , wherein:
said outer shell and said inner shell are elastomeric so that said outer and inner shells elastically deform in response to pressure applied and said inner and outer shells then spring back to original un-deformed shapes.
