  • Patent number: 12317862
    Abstract: A pet treat holder having a flexible outer housing with a center opening. A channel is disposed through a thickness of the flexible outer housing and radially bisects the center opening. An inner sleeve is fixed within the channel. A threaded fastener is movably disposed within the inner sleeve and adapted to be moved in a forward and reverse directions. When the threaded fastener is moved forward through the inner sleeve by twisting in a first direction, an end of the fastener secures and restricts movement of an object. The object is tightly held under compression between the fastener and the flexible outer housing. When the threaded fastener is moved in reverse through the inner sleeve by twisting in a second direction, the end of the fastener is moved away from and releases the object being tightly held under compression between the fastener and the flexible outer housing.

  • Patent number: 11617351
    Abstract: A single piece pet treat holder. The holder having an outer perimeter shape with a first thickness. An inner perimeter shape having an opening with a central aperture located therein. The opening extending through the first thickness and having a plurality of flexible projections extending toward the central aperture. Each of the flexible projections terminating in an enlarged tip. The flexible projections and the enlarged tips are configured to restrict removal of an object when the object is twisted in a first direction through the opening. The flexible projections and the enlarged tips are configured to release the object when the object is twisted in a second direction opposite the first direction.

  • Patent number: 11000014
    Abstract: A pet treat holding device designed to secure rigid pet treats and prevent dogs from choking on the treat, thereby eliminating the risk of stomach blockage and other health hazards. Through the application of compression and friction, the holder creates a gripping force around the rigid treat that prevents a dog from extracting a large piece of the treat, which could be hazardous if ingested. The pet treat holder is comprised of two rubber parts, the torus shaped housing surrounding an interior aperture. The treat is secured by compression and friction created by the center aperture. After inserting the treat stick into the opening and applying a twisting motion, securing the treat in place, the user can then present the treat to the dog. Because of the twisting lock action, the dog cannot remove the stick by chewing or pulling.
