  • Patent number: 9474986
    Abstract: A block-forming toy includes a plunger, a mold and an ejector plate. The plunger includes a shaft that passes through a barrel. The two pieces are able to move with respect to one another. Each piece connects to either the mold or the ejector plate, using male and female locking mechanisms. Subsequent to assembling the toy, the mold may be filled and packed with a moldable material. By pulling the plunger up to move the mold upwards relative to the ejector plate, and thus relative to the casted article, the block-forming toy may be used to easily remove the formed block of moldable material from the mold. A variety of mold shapes may be used to create additional blocks to form structures of moldable material. Examples of moldable material include sand and snow.

  • Patent number: 8651055
    Abstract: A pet bowl device designed primarily for pet owners comprises a bowl unit and an insert component. The bowl unit comprises an interior and exterior portion, with the insert component being positioned on the interior portion. The insert component comprises a top surface and a bottom surface and a plurality of individual openings positioned in a spaced apart relationship along the top surface. The plurality of individual openings is smaller in diameter than the bowl unit. The individual openings will divide up the serving size of pet food. Thus, the individual openings separate the food into smaller sections, which prevents the pet from opening their mouth wide enough to consume large gulps of food at once. Pets will then be forced to take smaller bites while eating, which slows down the rate at which the pet consumes its food and aids in the prevention of abdominal bloating (GDV).

  • Patent number: 4596073
    Abstract: An apple corer having four molded plastic components are fitted together to form the invention. They are a hollow cutting tube, a core remover slidable along the cutting tube, a handle attached at the end of the cutting tube, and a compression plug inserted at the same end for locking the handle in place. The tip of the cutting tube has serrated teeth for smooth boring into the apple. In operation, the handle is oscillated while applying pressure to it. This causes the cutting tube to bore through the apple. The tube is removed from the apple and the resulting core left in the tube is ejected by sliding the core remover towards the tip of the cutter. The corer can also be used for partial removal of the apple core when stuffed apples are desired. In this situation prongs are attached to the end of the core remover. The cutter is bored partially into the apple, the core remover is slid against the face of the apple causing the prongs to impale the apple and hold the core in place.

    Abstract: A threaded blade holder for cutting an opening in a flexible externally threaded closure element on a pail or container. The holder comprises a hollow internally threaded tubular body. A retaining member, comprising a pointed spike, is slideably disposed in a central aperture in the top of the tubular body to perforate the closure element and to relieve internal pressure in the pail through space between loosely fitting threads on the blade holder and the closure element. A pointed cutting blade, having a single cutting edge, extends downwardly from the top of the tubular body such that rotation of the tubular body onto the externally threaded closure element of the pail causes the blade to engage the upper surface of the closure element to cut a circular hole therein. However, the blade does not cut into material adjacent the periphery of the hole when the tubular element is removed from the externally threaded closure element.
