System and method for producing toy balls for pets
A method of producing toy balls for pets, including: manufacturing distorted sphere balls with an opening in the distorted area using injection molding; sealing the opening of the distorted sphere balls to form uni-body sphere-shaped balls. The material used in the production of these toys can be rubber, thermoplastic elastomers, or thermoplastic rubber. This method allows to manufacture toy balls with no detached parts in the case of broken joints when the balls are chewed or torn apart by the pets. Thus, the ball can help to keep the pets from endangering themselves by swallowing detached parts of pet toy balls.
1. A pet toy comprising:
a unibody ball shell comprising a first region and a second region,
wherein the first region comprises a partial sphere shape including a transition edge,
wherein the second region comprises a shape extending from the transition edge of the first region,
wherein the second region defines a first closure of an interior void of the second region of the unibody ball shell,
wherein the first closure comprises a sealing joint affixing a slit bounded by a first curved lip and a second curved lip joining at opposite vertices along a length on the second region, wherein the sealing joint affixes the slit closed by affixing the first curved lip to the second curved lip along at least a portion of the length of the slit,
wherein a curvature of the first curved lip and a curvature of the second curved lip are both at least partially flattened to be at least partially linear along the sealing joint, in response to the affixing,
wherein at least a portion of the sealing joint affixing the slit is positioned at an outermost distal point of the second region as measured from the center of the first region,
wherein the vertices lie within a single plane that extends through a center of the first region,
wherein the single plane defines a cross-section of the pet toy oriented to bisect two identical hemispheres of the unibody ball shell, and
wherein the second region comprises a spherical shape having a different radius than the first region.
