Abstract
A lid assembly and a method for assembling the lid assembly. The lid assembly may include: an open-loop clamp band configured to secure the container lid to a container opening, the open-loop clamp band biased towards a closed position; and a closure assembly coupled to the open-loop clamp band. The closure assembly may include: a pair of lugs including a threaded lug and an unthreaded lug respectively affixed to opposing ends of the open-loop clamp band; a clamp bolt receivable by the pair of lugs, the clamp bolt having a bolt head to be positioned proximal the unthreaded lug; and a jam assembly for receiving the clamp bolt, the jam assembly securable at a calibrated position along the clamp bolt and between the pair of lugs.
Claims18
An apparatus for sealing a container lid to a container containing nuclear waste and/or toxic material, the apparatus comprising:
- a lid assembly comprising:
- an open-loop clamp band configured to secure the container lid to a container opening, the open-loop clamp band biased towards a closed position;
- and
- a closure assembly coupled to the open-loop clamp band, the closure assembly including:
- a pair of lugs including a threaded lug and an unthreaded lug respectively affixed to opposing ends of the open-loop clamp band;
- a clamp bolt receivable by the pair of lugs, the clamp bolt having a bolt head to be positioned proximal the unthreaded lug;
- and
- a jam assembly for receiving the clamp bolt, the jam assembly being positioned at a predetermined calibrated position along the clamp bolt relative to the bolt head and between the pair of lugs,
- an annular weight for overlaying a region proximal to a perimeter of the container lid to impart a downward sealing force at an interface between the container lid and the container opening, wherein the downward force at the interface seals a gap defined by the container lid and the container;
- and
- a drip tray configured to be positioned on a surface of the container lid for receiving excess substance from a container fill head, wherein the surface opposes a side of the container lid configured to seal the container opening,
- wherein the annular weight is a ring-shaped weight having a hollow central region, and
- wherein the drip tray is positioned within the hollow central region of the annular weight.
An apparatus for sealing a container lid to a container, the apparatus comprising:
- a lid assembly comprising:
- an open-loop clamp band configured to secure the container lid to a container opening;
- and
- a closure assembly coupled to the open-loop clamp band;
- an annular weight for overlaying a region proximal to a perimeter of the container lid to impart a downward sealing force at an interface between the container lid and the container opening, wherein the downward force at the interface seals a gap defined by the container lid and the container;
- and
- a drip tray positioned on a surface of container lid for receiving excess substance from a container fill head, wherein the drip tray and the annular weight are configured to be positioned concentric with the annular weight.
A method of assembling a lid assembly for a container lid, the method comprising:
- extending a clamp bolt through an unthreaded lug, the unthreaded lug affixed to a first open end of an open-loop clamp band;
- engaging the clamp bolt with a jam assembly;
- threading the clamp bolt into a threaded lug, the threaded lug affixed to a second open end of the open-loop clamp band;
- affixing the jam assembly at a calibrated position along the clamp bolt relative to the bolt head, the jam assembly positioned between the threaded lug and the unthreaded lug,
- coupling an annular weight to the container lid, the annular weight positioned to overlay a region proximal to a perimeter of the container lid to impart a downward sealing force at an interface between the container lid and a container opening of the container, wherein the downward force at the interface seals a gap defined by the container lid and the container, wherein the annular weight is a ring-shaped weight having a hollow central region;
- and
- coupling a drip tray to the container lid, the drip tray configured to be positioned on a surface of the container lid for receiving excess substance from a container fill head, wherein the surface opposes a side of the container lid configured to seal the container opening, wherein the drip tray is positioned within the hollow central region of the annular weight.
