Abstract: A liquid dispensing closure for bottles and the like comprising a one-piece body having an end wall for covering the mouth of the bottle and a depending skirt for threading onto the neck of the bottle. A dispensing aperture in the end wall is surrounded by a spout that affords directional control of a stream of liquid being dispensed and reduced dribbling when dispensing is discontinued. A flap is hinged on the end wall to open and close the aperture with an associated depending plug that fits in the spout. The end wall, spout and hinged flap are arranged in a manner relative to one another that permits the flap to be advantageously molded in an upright position.

Abstract: A package, particularly suited for containing viscous foodstuff, comprising a wide-mouth generally rectangular container and a dispensing closure. The closure seals onto the container with a push-on motion and includes a resealable flip-up hinged lid. The container is originally sealed, after being filled, with a seal membrane applied to the container mouth. The closure is configured to permit the seal membrane to be conveniently removed from the container mouth while the closure remains assembled on the container.

Abstract: A dispensing closure with a hinged flap for conveniently opening and closing a dispensing aperture. The closure is a one-piece molded part having an integral living hinge. A mechanism for releasably locking the flap in a stay-open position and thereby resisting any tendency of the hinge to resiliently bias the flap towards a closed position is provided. The stay-open mechanism comprises a cooperating pair of surfaces molded into the flap and main body of the closure which are arranged to snap into and out of locking engagement when the flap is deliberately moved into or out of the open position.

Abstract: Screw on caps for bottles that have an anti back off feature formed on a hinged tab of the cap engaging detent teeth below the threads on the bottle. The hinge has a unique configuration that enables the tab to snap into and hold a gripping position while avoiding temporary distortion or creep. The detent teeth are particularly suited for use with blow molded bottles and are capable of restraining a cap within a small angle of a fully tightened position to avoid any significant back off and potential leakage. In one embodiment, the anti back off feature is provided in a child resistant cap while in another embodiment this feature is provided in a simpler continuous thread cap.

Abstract: A screw-on closure for bottles that initially works with an induction seal liner and provides a leak resistant reseal on the bottle after the liner is removed. The closure has a unique annular convex sealing surface that overlies the mouth of the bottle. The sealing surface and the closure body area supporting it are sufficiently massive to withstand the heat generated in an induction liner sealing process and have a geometry that promotes a line contact with the mouth of the bottle to ensure a drip resistant reclose. A dispensing aperture of the cap is sealed by a hinged flap that has its sealing surface areas strategically located relative to the hinge to ensure repeated drip free opening and closing dispensing operation.

Abstract: An injection-molded thermoplastic closure with shake-and-spoon apertures and associated flaps for selectively closing and opening the apertures. The flaps are releasably retained in their closed positions by catch elements which provide retention forces that are relatively insensitive to dimensional and shape variations in the body resulting from the molding process. In one embodiment, the cap has “freeze points” and a gate location that reduce the tendency of the cap to assume an oval condition when cooled from molding temperatures. A wide sealing ledge cooperates with a central support for a liner seal positioned in the cap to seal the mouth of a container.
