Abstract: A container lid and lock ring combination includes a lid for a container and a lock ring configured to extend loosely around the lid. The lock ring is configured to be tightened for securing the lid to a container. A joint connects the lid and the lock ring to one another.

Abstract: A container lid has a top panel defining a top side and an underside opposite the top side; a channel extending annularly around a periphery of the top panel, the channel open toward an underside direction on the lid; and a first wiper seal and a second wiper seal protruding downward from within the channel The first and second wiper seals are spaced apart from one another in a radial direction. When the lid is attached to a container to close off a top opening, the first and second wiper seals contact a surface of a container rim such that the first wiper seal bends radially inward relative to the container rim and the second wiper seal bends radially outward relative to the container rim.

Abstract: A lock ring for securing a lid to a container has a ring shaped body with a first end and a second end. A clamping pin is exposed near the first end and a lever is connected near the second end and has a hook thereon configured to engage the clamping pin. The lever is pivotable between a closed position and an open position. The hook is configured to selectively engage the clamping pin and draw the first and second ends to one another with the lever moved to the closed position and capable of disengaging the clamping pin the lever in the open position. The body, lever, and lock pin are integrally formed of a one-piece unitary structure and the lever is connected via a living hinge to the body.

Abstract: A low profile lock ring for securing a lid to a drum-type container has a body with a discontinuous ring shape and two free ends. The body has an annular wall and two spaced apart flanges forming a clamping channel facing radially inward. The two flanges define a profile height of the body. A lever has a grip section and a pivot section at opposite ends. The pivot section is pivotally attached to the body near a first of the free ends. The lever is pivotable between a closed position and an open position and has two walls spaced from one another and connected by a third wall. The spacing of the two walls defines a profile height of the lever. A lever end is adjacent the first free end of the body and is formed by the annular wall continuing to the first free end and the two flanges terminating short of the first free end.

Abstract: A closure system including a polymeric split ring clamp and a polymeric lid for a polymeric drum. To maintain the integrity of the closure, the lid rim region is formed having an annular restraining notch which cooperates with twist inhibiting blocking components formed within the interior of a cooperating inwardly opening polymeric split ring clamp. The blocking component may be provided as a sequence of regularly spaced block-like protuberances located within the inward upwardly disposed region of the ring clamp. A secondary closure arrangement is provided with the split ring clamp which receives a polymeric banding strap to prevent one end of the split ring from disengaging with an associated pivot arm. When the split ring clamp is in a fully open or pre-clamping mode orientation, a capture groove is formed with the ring pivot shaft formed at one end of the split ring clamp.

Abstract: A molded lid having an intermediate region configured as a sequence of waves, each of curved cross-section forming successively occurring crests and troughs, and exhibiting amplitudes increasing in value from the lid center toward the rim. The waves terminate at a ring band which is located to slide in adjacency with the inwardly disposed side of a plastic drum. The lid is provided with a polymeric gasket which is retained in position by a retainer band which is insertable in sliding compressive engagement within a retainer cavity.

Abstract: A split ring clamp for retaining a lid upon an enclosure such as a plastic or fibrous drum is provided which is formed entirely of polymeric material such as a high molecular weight, high density polyethylene copolymer. The assemblage includes two parts, a channel-form split ring and a pivot arm joining the two ends of the split ring together over the rim structure of a container. One end of the ring supports an integrally formed pivot shaft receiving notch as well as an outwardly extending toe with a rearwardly disposed contact surface. The opposite side of the ring is formed having a receiver channel within which there is provided an inwardly depending toe with a rearwardly facing contact surface. The pivot arm is formed having a transversely disposed arm pivot shaft and a ring pivot shaft receiving notch having a shaft access opening which is outwardly disposed and extends to a shaft bearing surface. Such an arrangement permits a more thin profile for the ring and pivot arm assembly.

Abstract: A clamping ring for retaining a lid upon an enclosure such as a fibrous drum is provided which is formed entirely of polymeric material such as a high molecular weight, high density polyethylene copolymer. The assemblage includes only two parts, a channel formed split ring and a pivot arm joining the two ends of the split ring together over the rim structure of the container. One end of the ring supports an integrally formed pivot shaft receiving notch and the opposite end of the ring is configured having a receiver channel with spaced-apart sides and an outwardly disposed opening. The inwardly-facing internal surfaces of the receiver channel are slideably movable in adjacency over the side surfaces of the opposite side of the ring and a ring pivot shaft extends between the spaced-apart sides of the receiver channel. The pivot arm cooperates with the split ring and has a pivot end formed with a transversely disposed arm pivot shaft and a ring shaft receiving notch spaced therefrom.
