Abstract: A pouring device for pouring lubricating oil into the oil filler neck of a conventional engine. The pouring device is adapted to prevent unwanted spilling of oil onto the exterior surface of the engine block during the pouring operation. The pouring device has a cylindrical connecting neck portion which is adapted to be threadaly mounted over the discharge aperture of a conventional lubricating oil container. The connecting neck portion extends integrally into a spout. The spout has an inlet surface. A sealing membrane is hingely connected to the connecting neck portion, adjacent the inlet surface. The sealing membrane is adapted to pivot between a closed position wherein it prevents the lubricating oil from flowing through the inlet aperture and an open position wherein the sealing membrane allows the lubrificating oil to flow through the inlet aperture. The sealing membrane is adapted to be releasably locked in its close position by a locking lip which abuts against its peripheral edge.

Abstract: A receptacle cover is disclosed incorporates an actuating trigger connected to a pair of biased valves that seal off the dispensing conduit and the relief vent from the top side of the cover. This construction isolates most of the linkage between the valves and the actuator from the contents of the receptacle. The actuator is a trigger located proximate the upper portion of a handle extending from the cover, and is linked to the valves by a wire that extends to, and moves, a rotating rod that is perpendicularly disposed in relation to the wire. The rod, in turn, is attached to the valves by additional wires that force them open against their proximate leaf springs. The dispensing conduit forms a plenum or chamber that functions in a manner similar to a straw by extending upwards from the cover. This construction prevents inadvertent leakage or fluid build up on the exterior of the receptacle.

Abstract: A one-piece closure for dispensing product from a container has a cap secured to the container and a lid connected to the cap by a support arm through an integrally molded hinge. The support arm is pivoted by the hinge between a pair of upstanding projections on the end wall of the cap. Ribs projecting laterally from the support arm engage the projections to maintain the lid opened when the container is inverted to dispense product. When the lid is pushed closed, the ribs deform to allow the support arm to pass between the projections. In one embodiment, side edges of the ribs engage upwardly facing cylindrical camming surfaces on the projections. In another embodiment, the outer surfaces of the ribs engage confronting flat surfaces on the two projections. In the closed position of the lid, the ribs in both embodiments are received in recesses in the projections so that they do not become permanently deformed and loose their effectiveness over time.

Abstract: The present invention is a toy water bow which is operated by selectively releasing water from a water reservoir that is pressurized with air. The present invention is a toy device formed in the general shape of an archery bow that has a manually operated air pump incorporated into it. The air pump pressurizes a water reservoir and consequently exerts pressure on water contained therein. The pressurized air and water have an avenue of release that is regulated by a pull mechanism of the invention. When no force is applied to the pull mechanism, the pressurized air and water are held at bay with no means of release from the reservoir. When force is applied to the pull mechanism in a predetermined manner, water is released from the pressurized reservoir and is channeled through a narrow nozzle. The escape of the water through the narrow nozzle creates a stream of propelled water in the form of an "arrow" of predetermined length.
