  • Patent number: 8651319
    Abstract: Lid for a container for filling the container from above, the opening being closable by a pivotable closure element mounted on an inner side of the lid so as to be rotatable about a first axis (X) which axis is horizontal when the lid is located on top of the container. The closure element includes a first part for closing the top of the container located on one side of the axis (X), and a second part as a counterweight on the other side of the axis (X). A pivotable bias element is rotatably mounted on the inner side of the lid on a second axis (Y) which is parallel to the first axis (X). The bias element is biased onto the second part by gravity and causes the first part to be pressed to the opening.

  • Patent number: 8286828
    Abstract: A storage/transport container has a plurality of walls defining an upwardly open vessel having an upper rim and a generally flat cover panel hinged on one of the walls and having an inner edge. The rim has opposite to one of the walls structure forming another inner edge. The cover panel is pivotal into a closed position with the inner edges juxtaposed, retaining formations projecting generally perpendicularly from the inner edge of the cover panel and oppositely from the other inner edge that fit together in the closed position. Hooks are formed on the edges and positioned so as to be opened directly at each other in the closed position. The hooks normally are spaced apart but, on deformation of the cover panel, hook together and preventing separation of the edges.

  • Patent number: 7984822
    Abstract: A kiln having a body with an internal chamber accessible via an opening which normally is closed by a closure that is movable. Lift apparatus effects movements of the closure between its closed and opened positions. The lift apparatus includes an arm which overlies the closure and is pivoted to a support independently of the kiln body for rotation about a second axis that is spaced a selected distance from the axis about which the closure rocks. The lift arm is connected to the closure by a pivot coupling which maintains the lift arm and the closure substantially parallel and uniformly spaced apart throughout the movements of the closure. The pivotal connection of the lift arm to the closure enables relative movement of the lift arm and the closure during movements thereof to avoid imposing appreciable stress on either the arm or the closure.

  • Patent number: 7341165
    Abstract: A lid for a container includes a side element extending from a front of the lid to a rear of the lid. A fulcrum point is formed at one end of the side element and is disposed adjacent to a rear of the lid. A rear surface of the lid includes a portion that projects upwardly and rearwardly to a furthermost rear point that is displaced rearwardly a predetermined distance relative to the fulcrum point. A counter-balance weight is positioned on the furthermost rear point of the lid. Wherein when the lid is raised, the weight of the lid and the counter-balance weight provide a force for raising the lid and to selectively maintain the lid in an open position. When the lid is lowered, the weight of the lid and the counter-balance weight provide a force for closing the lid.

  • Patent number: 6173861
    Abstract: A waste container assembly comprises a container body, a lid body, a flange and a door. The container body has an upper rim. The lid body has an outer surface extending from a top of the lid body to a lower portion of the lid body. The lower portion of the lid body is shaped and adapted for engagement with the upper rim of the container body. The flange extends from the lid body and has an inner rim that at least partially defines an opening in the lid body. The door is positioned adjacent the opening in the lid body and is pivotally connected to the flange for selectively moving the door between open and closed positions relative to the lid body. The door is adapted to substantially cover the opening in the lid body when the door is in its closed position. In another embodiment, the door pivots about a pivot axis and has a rim engaging portion adapted for engagement with the inner rim of the lid body when the door is in its closed position.

  • Patent number: 6050446
    Abstract: A lid assembly for a process chamber. The lid assembly includes a hinge having a hinge mount affixed to the chamber and a hinge arm. A pin extends from the hinge mount through an elongated slot in the hinge arm allowing both rotational and longitudinal motion of the hinge arm relative to the hinge mount. A support frame attached to the hinge arm has two side arms that extend perpendicularly from the hinge arms toward the front of the chamber. The lid is pivotally connected to the side arms by a pivot connection aligned with the center of mass of the lid. A detent extends from the lid through a slot in the side arm at a position offset from the pivot connection. The detent and slot serve to limit the allowable rotation of the lid relative to the lid support frame. Thus, the lid is allowed to float over the opening of the chamber as the lid is closed so that the lid may be positioned in parallel alignment relative to the opening of the chamber before being secured to the chamber.

  • Patent number: 6024238
    Abstract: A trash receptacle with a slowly closing lid is provided. A band of elastomeric material is provided around the rim of the trash receptacle opening to soften contact between the lid and the receptacle. The lid of the trash receptacle may be opened by depressing a foot pedal. When it is desired to close the trash receptacle lid, the foot pedal may be released. This causes the lid to close under its own weight. The lid has a damper arrangement that retards movement of the lid as the lid closes. The slow movement of the lid that is provided by the damper arrangement allows the lid to close quietly and safely by itself.

  • Patent number: 6003705
    Abstract: A portable bulk storage container having a counterweight mechanism for opening and closing a heavy lid. The container comprises a substantially gas and liquid tight tank secured inside of a frame. An opening is positioned on a front portion of a top of the tank. A lid is pivotally connected to the top of the tank for sealing the opening. A pair of fulcrums or connecting members extend from opposite sides of a rear portion of the lid. A counterweight is attached to each fulcrum. Each counterweight has an elongated lever end which extends away from the rear of the lid such that the counterweight can be used to rotate the lid between closed and open positions. Each counterweight is positioned beyond a side wall of the tank such that the counterweights can be rotated along the side wall of the tank, thereby effectively utilizing the limited amount of space available inside of the frame.
