Abstract
A play ball has a rubber shell filled with resilient foam having an entire outer peripheral surface thereof intimately attached by heat fusion and adhesive to an entire interior surface of the shell. Such attachment enables the foam to provide additional resiliency by foam tension, as well as by foam compression, thereby significantly extending the effective bounce life of the ball. A seamed dog chew toy has essentially similar construction such that the increased retention force provided by the intimate attachment of the foam to the shell resists the chewing force of the dog popping a seam improving durability.
Claims7
A method for making a play ball comprising the steps of:
- providing two, resiliently flexible, complementary elastomeric half shells having engageable rims;
- providing a resiliently compressible foam body with a periphery shaped to fill a shell assembled by engagement of said rims;
- assembling the half shells together enclosing the foam body by engaging said rims;
- heating the assembly in a match mold, both fusing the rims together and fusing an entire interior surface area of the elastomeric half shells to an entire periphery of the foam body and,
- further comprising the step of coating the periphery of the foam body with adhesive prior to enclosure in the half shells so that the periphery of the foam body is also attached to the half shells by the adhesive.
