Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application claims priority to U.S. Provisional Patent Application No. 63 / 16,652, entitled "CONTAINER CLOSURE DEVICE AND METHOD OF OPERATING THE SAME," filed April 28, 2020, the entire contents of which are incorporated herein by reference.

[0002] FIELD OF THE DISCLOSURE The present disclosure relates generally to containers, and more particularly to a container closure device and a method of operating the same. [Background technology]

[0003] Materials that may be hazardous or for which exposure should be minimized, such as nuclear waste or toxic materials, may be in the form of a solid, liquid, or a combination thereof. The container may be configured to isolate, store, or transport such materials. In some embodiments, the container may be configured to contain the material and mix the material with an immobilization reagent to create a solidified matrix, thereby reducing the likelihood that the material contained within the container will leak or leach into the environment. In some other embodiments, the container may be sealed by securing a container lid to the container opening to prevent the material from leaching into the environment. Summary of the Invention [Problem to be solved by the invention]

[0004] Embodiments described herein provide a lid assembly for a container lid. In some embodiments, the lid assembly can include features based on a previously certified closure device, and the closure device can be enhanced with features that allow a technician to seal the container from a physical distance from the container.

[0005] In some situations, a technician may repeatedly tap the periphery of the container lid at the interface between the container opening and the container lid to increase the integrity of the seal at the interface. Such manipulation may increase the likelihood of hazardous materials being expelled from the container, thereby potentially exposing the technician to the hazardous materials. Embodiments described herein provide a device adaptable to remotely apply a downward force to the container lid to seal the container. In some situations, a device adaptable to apply a downward force to the container lid can increase the integrity of the seal between the container lid and the container opening.

[0006] In some circumstances, after a container and associated closure device has received certification or regulatory approval, modifications to the container or associated closure device may, in some circumstances, invalidate that certification. Some embodiments of the present disclosure include features that enable remote operation of the container closure device and can avoid invalidating prior certification or regulatory approval.

[Figure 8] 1 illustrates a method of assembling a lid assembly for a container lid according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0043] The container can be configured to contain the material to be stored or transported. For example, a drum or other container type can be adapted to store or transport the material. A technician can perform manual operations that reduce the chance of a contaminant breaching the seal between the container and the container lid. For example, concerns related to the safety of operations performed by a technician sealing or unsealing a container can be alleviated when the material in the container cannot pose a hazard to the environment or humans.

[0044] In some situations, a container may be adapted to store or transport hazardous materials, such as substances that may be harmful to the environment or humans. Hazardous materials include substances that pose a health hazard to humans or cause undesirable changes to the environment, such as ionizing radioactive materials, among others. In some situations, a container storing hazardous materials may exceed contact handling limits, such as 0.2 Roentgen Equivalent Man per hour (Rem / hr). It may be beneficial to provide a container closure device that can be remotely operated. Remotely operating a closure device adapted to seal a container storing or transporting hazardous materials can reduce the risk associated with technicians coming into contact with the hazardous materials.

[0045] A method for enclosing hazardous material in a container can include securing a container lid to an opening or rim of the container. In some situations, a technician can place the container lid on the container opening and apply a force to the container lid to create a seal at the interface between the periphery of the container lid and the rim of the container. The technician can apply a downward force to the container lid with a mallet or other striking device. However, striking the container lid can cause hazardous material to splash out of the container, potentially exposing the technician to the hazardous material. It can be beneficial to provide a device adaptable to remotely apply a downward force to the container lid to seal the container. In some situations, it can be beneficial to apply a substantially uniform downward force around the periphery of the container lid, thereby increasing the integrity of the seal between the container lid and the container opening.

[0046] In some situations, upon utilizing a container to contain, store, or transport hazardous materials, some regulatory authorities may require the container and closure device to undergo one or more certification tests. For example, in some jurisdictions / countries, a container containing hazardous materials may be required to comply with certification requirements, such as drop test requirements, water immersion test requirements, etc., to be approved for transportation on publicly accessible roads. Such certification standards may provide assurance that the container will not be destroyed or damaged based on a set of test criteria. In some situations, obtaining regulatory approval or certification is a laborious process and may be time consuming or costly.

[0047] After a container and associated closure device has received certification or regulatory approval, modifications to the container and associated closure device may, in some circumstances, invalidate the certification. It may be beneficial to provide reinforcements to the container closure device so as not to invalidate the prior certification or regulatory approval.

[0048] Embodiments described herein include a lid assembly for a container lid. In some embodiments, the lid assembly can include features based on previously validated closure devices and can be enhanced with features that allow a technician to seal the container from a relatively large physical distance away from the container. In some embodiments, the lid assembly can include a device that overlaps an annular weight device in a region proximal to the periphery of the container lid. The annular weight device applies a downward sealing force to the interface between the container lid and the container opening, allowing the technician to position themselves from a relatively large physical distance away from the container.

[0049] By increasing the distance between the technician and the containers storing the hazardous materials and by minimizing the duration that the technician may need to be in physical proximity to such containers, the technician's exposure to the hazardous materials can be reduced.

[0050] Embodiments of the present disclosure may describe generally cylindrical containers (e.g., commercially available 113.6 liter or 208.2 liter (30 or 55 gallon) drums) for isolating, storing, or transporting waste materials. Of course, other container types, shapes, or sizes may be used. For example, containers for containing, storing, or transporting hazardous materials may have other non-circular cross-sectional shapes.

[0051] Referring to FIG. 1A, which illustrates a cutaway perspective view of a vessel 110 according to an embodiment of the present disclosure. The vessel 110 may be generally cylindrical in shape. For example, the vessel 110 may be a 55-gallon container or drum. Other sizes and vessel types may also be used. In some embodiments, a device may be disposed within the drum for interacting with a substance contained therein. Such a device may include a mixing paddle or other device.

[0052] In some embodiments, the container 110 can include a container lid 114 that is mounted to an opening in the container 110. The container lid 114 can be adapted to seal the container 110, thereby isolating the material contained within the container 110 from the external environment.

[0053] The container 110 may have a rolled-up top rim 112 or a curled opening. The rolled-up top rim 112 may be complementary to the periphery of the container lid 114.

[0054] 1B, which illustrates an enlarged, partial cutaway view of the container illustrated in FIG. 1A. In some embodiments, a gasket 116 can be positioned between the rolled-up top rim 112 and the peripheral edge of the lid 114. When the lid 114 is installed over the opening of the container 110, the gasket 116 can create a seal that prevents waste material from leaking or passing into the environment outside the container. In some embodiments, the gasket 116 can be constructed of rubber. Other types of materials can also be used for the gasket 116.

[0055] In some embodiments, an open-loop clamp band can be configured to secure the container lid to the opening of the container 110. For example, the open-loop clamp band can be a clamp ring 120 adapted to wrap around the periphery of the container lid 114 and a mating region proximal to the rolled-up upper rim 112 of the container 110. When the clamp ring 120 is tightened around the periphery of the container lid 114, the clamp ring can compress the gasket 116 and create a seal at the interface between the container lid 114 and the container opening.

[0056] 1, the rolled top rim 112 of the container and the peripheral edge of the container lid 114 are shown as convex interfaces. In some embodiments, the interfaces between the container lid 114 and the container opening are each concave, and the open-loop clamping band can be configured to wrap around the combination of the container lid peripheral edge and container rim having such a concave contour and can abut the container rather than the container lid.

[0057] Referring to Figure 2, this illustrates a clamp ring 120 and closure assembly. The clamp ring 120 can be configured to wrap around a container lid to secure or fasten the container lid to the container of Figure 1. In some embodiments, the clamp ring 120 can be an open-loop clamp band. For example, the clamp ring 120 can be a generally circular ring having an opening with two open ends.

[0058] The clamp ring 120 can include a closure assembly coupled to the clamp ring 120. The closure assembly can be configured to tighten the clamp ring around the periphery of the container lid when the container lid is installed on the container opening and when the clamp ring 120 is wrapped around the container lid. When the clamp ring 120 is tightened to secure the container lid to the container opening, the clamp ring 120 can assume a closed position. When tightened, the clamp ring can compress a gasket (not explicitly shown in FIG. 2 ) to seal the container.

[0059] A closure assembly can be coupled to the open portion of the clamp ring 120. The closure assembly can include a threaded lug 122a and an unthreaded lug 122b. The threaded lug 122a and the unthreaded lug 122b can receive a clamp bolt 124. The clamp bolt can be positioned tangentially to the clamp ring 120. Figure 2 illustrates the clamp ring 120 in an open or unclamped position.

[0060] Rotating the clamp bolt 124 clockwise causes the bolt head of the clamp bolt 124 to advance the unthreaded lug 122b toward the threaded lug 122a, allowing the clamp ring 120 to be tightened around the container lid.

[0061] 2, a single locking nut 126 is positioned between the threaded lug 122a and the unthreaded lug 122b. The single locking nut 126 can receive the clamp bolt 124. When the clamp bolt 124 is rotated to tighten the clamp ring 120 around the container lid, the single locking nut 126 can be adjusted by rotating along the clamp bolt 124 and toward the unthreaded lug 122b.

[0062] During transport of the sealed container, the container may be subjected to vibration or similar shock motion. The single lock nut 126 can be tightened to abut the threaded lug 122b. By tightening the single lock nut 126 to abut the unthreaded lug 122b, movement of the clamp bolt relative to the unthreaded lug can be reduced when the sealed container is transported.

[0063] In this embodiment, a technician tightening the exemplary clamp ring 120 and closure assembly described with reference to FIG. 2 must repeatedly rotate the single locking nut 126 along the clamp bolt 124 and toward the threaded lug 122a while rotating the clamp bolt 124 because, at least, the unthreaded lug 122b biases and compresses the single locking nut 126. The unthreaded lug 122b compresses against the single locking nut 126 because, at least, the clamp ring 120 is configured to bias toward the closed position. For example, the clamp ring 120 in the closed position can have a ring diameter that is smaller than the ring diameter of the clamp ring 120 in the open position. In another embodiment, when the clamp ring 120 is in the closed position, the distance between the threaded lug 122a and the unthreaded lug 122b can be smaller than the distance between the threaded lug 122a and the unthreaded lug 122b when the clamp ring 120 is in the open position.

[0064] In the embodiment described with reference to FIG. 2 , a technician is required to repeatedly or sequentially rotate a single lock nut 126 (using a wrench) and clamp bolt 124 to tighten the clamp ring 120 around the periphery of the container lid, which can be challenging to perform remotely to seal the container. Because the technician must be physically near the container to (i) seat the clamp ring 120 around the combination of the container lid and the rim of the container opening, and / or (ii) tighten the clamp ring 120 illustrated in FIG. 2 to seal the container, performing such operations can increase the amount of time the technician is exposed to or in close proximity to the container. This can prevent the technician from reducing physical exposure to hazardous materials that may be present within the container. It would be beneficial to provide a closure device and method of operating the closure device that reduces the amount of time or requirements for the technician to come into close physical contact with the target container they are sealing.

[0065] In some situations, a technician can utilize a rubber mallet or similar tool to repeatedly strike the periphery of the container lid against the top rim of the container (FIG. 1) to reduce uneven tensioning of the clamp ring 120 against the container and container lid. In some situations, a technician can strike the clamp ring 120 to apply a generally similar downward force at multiple points around the clamp ring to seal the container.

[0066] Additionally, when the clamp ring 120 is bent in an unintended position (e.g., when the peripheral portion of the clamp ring is not on a single or horizontal plane), a technician can strike a portion of the clamp ring 120 to position the clamp ring 220 in place at the interface between the container opening and the container lid.

[0067] However, striking the periphery of the container lid and / or the clamp ring may encourage the splashing of hazardous materials within the container toward the container opening. Thus, striking the periphery of the container lid to increase the integrity of the seal at the interface between the container lid and the container opening may increase the risk to the technician of splashing such hazardous materials onto the technician. It would be beneficial to provide a device that applies a downward sealing force to the interface between the container lid and the container opening while reducing the technician's exposure to hazardous materials stored within the container.

[0068] 3, which illustrates a perspective view of a lid assembly 300 according to an embodiment of the present disclosure. The lid assembly 300 can be mounted to an opening of a container 310.

[0069] In some embodiments, the container 310 may be a cylindrical drum, and the opening of the container 310 may be substantially circular. The lid assembly 300 shown in FIG. 3 may be configured to mount to the circular opening of the container 310.

[0070] The container lid 302 can have a periphery that is complementary to the opening of the container 310. For example, the container lid 302 can be circular and have a diameter that is approximately the same as the diameter of the opening of the container 310.

[0071] The lid assembly 300 may include an annular weight 350 that overlaps a region proximal to the periphery of the container lid 302. For example, the annular weight 350 may be removably positioned on top of the container lid 302. When overlapping the container lid 302, the annular weight 350 may be concentric with (share a similar center point with) the container lid 302.

[0072] The annular weight 350 can be positioned adjacent to the outer surface of the container lid 302. In some embodiments, the annular weight 350 can be ring-shaped or donut-shaped and can be configured to apply a downward force to the container lid 302 or clamp ring 320 during operations to close or maintain a seal on the container 310.

[0073] The annular weight 350 can be configured to maintain a downward sealing force against a gasket installed between the container lid 302 and the opening of the container 310. For example, when the annular weight 350 is positioned adjacent to the outer surface of the container lid 302, the annular weight 350 can apply pressure to the gasket. A technician can then operate the clamp ring 320 to move to the closed position. While the annular weight 350 is placed on the container lid 302, the compressive force against the container lid 302 reduces the occurrence of liquids and solids passing through the gap between the container lid 302 and the container opening.

[0074] Furthermore, when annular weight 350 is positioned adjacent the outer surface of container lid 302, annular weight 350 can be positioned to maintain concentricity between container lid 302 and clamp ring 320 during tightening of clamp ring 320 around container lid 302. Thus, annular weight 350 can be configured to cause clamp ring 320 to maintain a generally circular shape in a horizontal plane during operations of removing or attaching the lid to the opening of container 310.

[0075] In some embodiments, the annular weight 350 can include a plurality of alignment fingers 352. In some embodiments, the alignment fingers 352 can be wedge-shaped. The alignment fingers 352 can be distributed around the circumference of the annular weight 350.

[0076] For example, the annular weight 350 illustrated in Figure 3 includes three alignment fingers 352 distributed at spaced locations around the outer edge of the annular weight. Although three alignment fingers 352 are illustrated in Figure 3, any number of alignment fingers 352 may be used to assist in positioning and maintaining the position of the annular weight 350 adjacent the container lid 302.

[0077] In some circumstances, when the annular weight 350 is lowered to overlap the top of the container lid 302, the wedge-shaped structure of the alignment fingers 352 can assist in aligning the annular ring 350 and the container lid 302.

[0078] In some embodiments, the clamp ring 320 can be an open-ended clamp band that can assume a closed position and an open position. When the clamp ring 320 is in the closed position, the diameter of the clamp ring 320 can be smaller than when the clamp ring 320 is in the open position. When the clamp ring 320 is in the open position, the clamp ring 320 can be installed to secure the container lid 302 to the container opening.

[0079] The clamp ring 320 can be configured to loosen from the periphery of the container lid 302 when the container 310 is unsealed or when a technician removes the container lid 302 from the container 310 .

[0080] The lid assembly 300 may include a closure assembly that couples to the open portion of the clamp ring 320. The closure assembly may have a pair of lugs including a threaded lug 322a and an unthreaded lug 322b. The threaded lug 322a and the unthreaded lug 322b may be secured to opposite ends of an open-loop clamp band, respectively.

[0081] The clamp bolt 324 may be receivable by the threaded lug 322 a and the unthreaded lug 322 b. The clamp bolt 324 may be rotated to tighten the open-ended clamp ring 320 around the periphery of the container lid 302. The clamp bolt 324 may have a bolt head to be positioned proximal to the unthreaded lug 322 b.

[0082] In some embodiments, the clamp bolt 324 can be pushed or inserted into the unthreaded lug 322b. In some embodiments, the clamp bolt 324 can have multiple threads along its shaft and can be threaded into corresponding threads on the threaded lug 322a.

[0083] In some embodiments, the closure assembly can include a jam assembly that receives the clamp bolt 324. In some embodiments, the jam assembly can include a pair of jam nuts 328 positioned between the threaded lug 322a and the unthreaded lug 322b.

[0084] A pair of jam nuts 328 can receive the clamp bolts 324. After the clamp bolts 324 are rotated to tighten the clamp ring 320 around the periphery of the container lid 302, one or more jam nuts 328 can abut the unthreaded lugs 322b to reduce movement of the clamp bolts relative to the unthreaded lugs when the sealed container is shipped. Further details are provided with reference to Figures 4A and 4B.

[0085] 2, where the jam nut may be a single or separate locking nut, the technician may need to (i) adjust the jam nut position along the clamp bolt (using a wrench), (ii) rotate the clamp bolt (using a socket), (iii) adjust the jam nut position along the clamp bolt, etc., in a repetitive sequence until the clamp ring is tightened to the desired position. Such an example operation requires a high degree of dexterity, and the technician may need both hands to perform such an example operation.

[0086] Furthermore, when a technician loosens the clamp ring from the periphery of the container lid to remove the container lid from the container opening, the clamp ring may be biased toward the closed position, and the technician may need to physically hold the clamp ring 320 in the loosened or open position. For example, when the unthreaded lug is unconstrained and the jam nut is positioned adjacent the threaded lug along the clamp bolt, the end of the clamp ring associated with the unthreaded lug may slide along the clamp bolt.

[0087] Therefore, in some situations, it may be beneficial to provide a closure assembly feature that maintains the clamp ring in an open position during removal of the lid assembly (based at least on reducing movement of the clamp bolt relative to the unthreaded lug).

[0088] Referring to FIG. 4A, this illustrates a perspective view of a closure assembly coupled to an open-ended clamp band, according to an embodiment of the present disclosure. The open-ended clamp band can be a clamp ring 420. In FIG. 4, the clamp ring 420 is illustrated in an open position 490a and a closed position 490b. The diameter of the clamp ring 420 in the closed position can be smaller than the diameter of the clamp ring 420 in the open position. By reducing the diameter of the clamp ring 420, the clamp ring 420 can be configured to secure a container lid to a container opening. By reducing the diameter of the clamp ring 420, the distance between the threaded lug 422a and the unthreaded lug 422b decreases.

[0089] 4, the closure assembly has a pair of lugs including a threaded lug 422a and an unthreaded lug 422b, which can be secured to opposite ends of an open-ended clamp band, respectively.

[0090] The threaded clamp bolt 424 can be receivable into the threaded lug 422a and the unthreaded lug 422b. When the clamp bolt 424 is rotated to tighten the clamp ring 420 around the periphery of the container lid or around the container opening (not shown in FIG. 4), the bolt head of the clamp bolt 424 advances toward the unthreaded lug 422b and applies a force that advances the unthreaded lug 422b toward the threaded lug 422a along the axis of rotation of the threaded clamp bolt 424. The threads of the clamp bolt 424 can engage the threads of the threaded lug 422a.

[0091] 1 and 2, when installing a single jam nut, a technician may need to perform a sequence of repeated rotational adjustments of the single jam nut and clamp bolt as the clamp ring is tightened around the periphery of the container lid. Such operations may be necessary because at least (i) the unthreaded lug is biased to press against the single jam nut, and / or (ii) the single jam nut must be rotated and advanced along the clamp bolt so that the threaded and unthreaded lugs can advance toward each other.

[0092] 1 and 2, for example, the closure assembly of FIG. 4 can include a pair of jam nuts 428. In some embodiments, jam nuts 428 can each have a thinner dimension or profile than jam nuts 328 of FIG. 3, such that the physical dimensions of pair of jam nuts 428 do not interfere with tightening of clamp ring 420.

[0093] In some embodiments, the pair of jam nuts 428 can be configured to assume a calibrated position along the clamp bolt 424. Thus, when the jam nuts 429 are secured in a calibrated position along the clamp bolt 424, the pair of jam nuts 428 can abut the threaded lugs 422a when the clamp ring 420 is in a closed or clamped position around the periphery of the container lid. The calibrated position can be predefined and can be a function of the diameter of the open-loop clamp band, the diameter of the container lid, or the diameter of the container opening.

[0094] To secure the pair of jam nuts 428 in a calibrated position along the clamp bolt, in some embodiments, each of the pair of jam nuts 428 may be positioned against the other of the pair of jam nuts 428 and torqued toward each other. By way of example, each of the pair of jam nuts 428 may apply approximately 70 ft / lbs of rotational torque to the other of the pair of jam nuts 428. Other torque amounts may also be used.

[0095] After a rotational torque is applied to the pair of jam nuts 428 in a direction toward one another, the pair of jam nuts 428 may assume a fixed position along the clamp bolt 424. That is, the clamp bolt 424 and the pair of jam nuts 428 may be configured as if the components were collectively a single assembly.

[0096] Once in the closed position 490b, the pair of jam nuts are positioned approximately adjacent to both the threaded lug 422a and the unthreaded lug 422b, thereby limiting movement of the clamp bolt 424 relative to the unthreaded lug 422b. Furthermore, when the pair of jam nuts 428 are positioned in a predetermined position along the clamp bolt (determined when the clamp ring is configured for the container), a technician performing the operation of tightening the clamp ring around the periphery of the container lid does not need to adjust the pair of jam nuts while rotating the clamp bolt with a socket.

[0097] As described herein, in some situations it may be desirable to maintain the position of the clamp bolt 424 relative to the unthreaded lug 422b so that the clamp ring 420 can be maintained in an open position for removal or installation of the container lid at the container opening.

[0098] In some other situations, the jam nut 428 can be fixed in a calibrated position along the clamp bolt, but the unthreaded lug 422b does not occupy a substantial gap or space between the jam nut 428 and the bolt head. Because the unthreaded lug 422b is not threaded and does not require a positive engagement with the clamp bolt 424, in some situations the unthreaded lug 422b can slide within the space between the jam nut 428 and the bolt head.

[0099] That is, if unthreaded lug 422b were to slide uncontrollably between jam nut 428 and the bolt head, clamp ring 420 may not maintain either the open or closed position. It may be beneficial to provide a feature that maintains unthreaded lug 422b in position between the bolt head and jam nut 428 so that clamp ring 420 can maintain a set open or closed position.

[0100] Referring to Figure 4B, which illustrates an illustration of the closure assembly in open and closed positions 490a and 490b, respectively, Figure 4B is generally similar to Figure 4A and additionally illustrates features that reduce movement of the clamp bolt 424 relative to the unthreaded lug 422b.

[0101] 4B, the closure assembly can include a standoff device 460 positioned between the unthreaded lug 422b and the jam nut 428 (e.g., a jam assembly). The standoff device 460 can be adapted to maintain the position of the unthreaded lug 422b relative to the bolt head. The standoff device 460 can be configured to limit movement of the clamp bolt 424 relative to the unthreaded lug 422b. Limiting movement of the clamp bolt 424 relative to the unthreaded lug 422b can maintain the open-ended clamp ring 420 in an open position when the clamp bolt 424 is in an unfastened position (e.g., an open position) relative to the threaded lug 422a.

[0102] In some embodiments, the spacing device 460 can include a pin that is received within an aperture in the shaft of the clamp bolt 424. The aperture can be positioned to receive a pin or the like along the shaft to maintain the unthreaded lug 422b against the bolt head of the clamp bolt. The aperture's location can be predetermined so that the clamp ring 420 is in a relaxed state when the closure assembly is in the open position 490a. In some embodiments, the pin 460 can be a cotter pin or similar engineered pin. The aperture can be positioned on the opposite side of the unthreaded lug 422b from the bolt head.

[0103] In some embodiments, the aperture may be a drilled hole in the shaft of the clamp bolt. In some circumstances, drilling a hole in the clamp bolt may void the regulatory certification of the closure assembly.

[0104] The embodiment described for the closure assembly of Figures 4A and 4B may allow a technician to remotely tighten the clamp ring 420 around the periphery of the container lid and around the container opening because at least one pair of jam nuts 428 are torqued together. Thus, the clamp bolt 424 may rotate as an integral component, eliminating the need for additional adjustment or manipulation of the pair of jam nuts 428. In this manner, a technician may not need to stand physically adjacent to the container opening to tighten the clamp ring 420, nor may they need to perform the repetitive sequence of adjusting the pair of jam nuts 428 and clamp bolt 424. As described above, the arm assembly may be configured to position the lid assembly over the container opening, and an extended-length socket wrench may be used to rotate the clamp bolt 424 and tighten the clamp ring 420 around the periphery of the container lid. The lid assembly can be adjusted (rotating the clamp bolt and jam assembly combination) with an extended length socket wrench, eliminating the need for a technician to physically stand near the container while tightening the container lid onto the container opening.

[0105] 4B closure assembly includes features that maintain the clamp ring 420 in the open position 490a, thereby eliminating the need for a technician to physically stand adjacent to the container to hold the clamp ring 420 in the open position during clamp ring 420 / container lid removal or installation. Reducing the need for a technician to physically handle and manipulate the container lid or closure assembly near the container opening reduces the technician's risk of exposure to hazardous waste materials.

[0106] In some embodiments of the closure assembly, the combination of features described herein allows the clamp ring to be held open during handling operations of the container lid and container.

[0107] As described herein, containers, container lids, or closure assemblies associated with storing and transporting hazardous materials may be subject to regulatory standards. Certain combinations of containers, container lids, and closure assemblies may be subject to certification testing. In some embodiments of the present disclosure, features of existing containers may be enhanced, for example, with features described with reference to FIGS. 4A and 4B , without invalidating prior certifications or test results. For example, replacing a single jam nut with a jam assembly (e.g., a pair of jam nuts, each having a low profile / thickness) between the threaded and unthreaded lugs of a closure assembly may not invalidate prior certifications of the container assembly, thus minimizing the cost of obtaining an improved container assembly. Furthermore, introducing a spacing device between one or more jam nuts and the unthreaded lugs may not invalidate prior certifications of the container assembly.

[0108] In some embodiments, containers for containing or storing hazardous materials (e.g., ionizing radioactive materials, among other materials) may be handled and transported in an environment that employs protective barriers to reduce exposure of machine operators or technicians. In some embodiments, the protective barriers may be configured to contain gaseous materials, aerosols, or airborne particles.

[0109] In some embodiments, a biological shielding barrier can be configured to reduce or contain ionizing radiation. Some environments for handling containers can include at least two regions: (a) a shielded enclosure area for handling materials that exhibit ionizing gamma radiation, and (b) a containment area for handling airborne radioactive alpha particles.

[0110] In some embodiments, prior to introducing the container assembly into an environment for handling hazardous materials, the following operations are performed: (a) modifying the existing clamp bolt to provide an aperture in a predetermined or calibrated location relative to the bolt head by drilling holes in the shaft of the clamp bolt; (b) replacing the existing single jam nut with a pair of jam nuts to receive the threaded clamp bolt; (c) generating a torque that urges each of the pair of jam nuts toward the other of the pair of jam nuts around the clamp bolt to effectively lock or secure the pair of jam nuts in a predetermined (e.g., calibrated) position so that the clamp bolt and the pair of jam nuts can rotate as an integral assembly; (d) inserting a pin into the drilled aperture so that the pin protrudes from either side of the through aperture, thereby maintaining the position of the clamp bolt relative to the unthreaded lug; and (e) The container assembly can be prepared based on one or more of the following operations: (f) removing the clamp ring (while in the open position) to ensure that the clamp ring is sufficiently loosened to lift it from the container opening during hazardous waste handling; or (f) placing an annular weight adjacent to the outer surface of the container lid so that the annular weight can maintain the peripheral shape of the clamp ring (e.g., within a single plane).

[0111] Referring to FIG. 5, which illustrates a perspective view of a closure assembly coupled to an open loop clamp band 520 in an open position 590a and a closed position 590b, according to an embodiment of the present disclosure.

[0112] The closure assembly illustrated in Figure 5 includes similar features to the closure assemblies described with respect to Figures 4A or 4B. Additionally, the closure assembly illustrated in Figure 5 has a spacing device including one or more Belleville washers 570. The Belleville washers 570 may be positioned between the unthreaded lugs 522b and the pair of jam nuts 528. The Belleville washers 570 may minimize movement of the clamp bolt relative to the unthreaded lugs 522b and may hold the clamp ring 520 open during installation or removal of the container lid.

[0113] Referring to FIG. 6, this illustrates a perspective view of a closure assembly coupled to an open-ended clamp ring 620 in an open position 590a and a closed position 590b, according to an embodiment of the present disclosure.

[0114] The closure assembly illustrated in Figure 6 includes similar features to the closure assemblies described with respect to Figures 4A or 4B. Additionally, the closure assembly illustrated in Figure 6 has a spacing device including a wedge 672. The wedge 672 may be positioned between the unthreaded lugs 622b and the pair of jam nuts 628 to minimize movement of the clamp bolt relative to the unthreaded lugs 622b and to hold the clamp ring 620 open during installation or removal of the container lid.

[0115] 7, which illustrates a lid apparatus 700 according to an embodiment of the present disclosure, which may be configured to operate with a container lid or lid assembly (e.g., lid assembly 300 of FIG. 3) for placing and packaging hazardous waste in a container, such as a cylindrical drum.

[0116] In some embodiments, the remote handling environment can include an apparatus configured to transport drums to one or more locations within the hazardous waste packaging environment, the apparatus can include an arm assembly that can couple to the lid assembly and install or remove the lid assembly from the drum.

[0117] 7, the device 700 can include an arm assembly having a rotating shaft 780 configured to couple to the lid removal device 700. The rotating shaft can be configured to rotate the lid device 700 toward or away from an opening in a container or drum. In some embodiments, the device includes a feature for transporting the container to a location proximate the arm assembly, and the arm assembly can be configured to fine-tune the position of the container lid 702 relative to the target container before seating the container lid 702 in the opening of the target container.

[0118] In some embodiments, the device can be configured to transport the container to a location proximal to the arm assembly and can be configured to rotate the drum via a configurable turntable to orient the drum in a predetermined position for a lid assembly or lid removal operation.

[0119] The lid assembly can include a container lid 702 and an annular weight 750 adapted to overlap an area proximate the periphery of the container lid 702. In some embodiments, when placed on top of the container lid 702, the container lid 702 and the annular weight 750 can be positioned concentrically with one another, thereby having aligned center points.

[0120] The lid assembly can include a clamp band or clamp ring (not explicitly shown in FIG. 7) and a closure assembly 708 coupled to the clamp ring. The closure assembly can have one or more features described in embodiments of the present disclosure.

[0121] The apparatus 700 can include one or more electromagnets 756 that can be coupled to the arm assembly. In embodiments in which the container lid 702 can be constructed of steel or a magnetic material, the one or more electromagnets 756 can be configured to couple to the container lid 702 when energized. The apparatus 700 can be configured to rotate the container lid 702 toward the container opening for installation of the container lid and sealing of the container opening.

[0122] In some embodiments, one or more electromagnets 756 may include an independent uninterruptible power supply configured to prevent accidental deactivation of the electromagnets 756, which may result in the container lid 702 being inadvertently released into the environment. In the above-described example, one or more electromagnets 756 may be temporarily coupled to the container lid 702, which is constructed of a magnetic material. When positioning and placing the container lid 702 over the container opening, one or more electromagnets 756 may be deactivated.

[0123] In some embodiments, the lid removal assembly 700 can include one or more configurable suction cups for picking up the container lid 702. In situations where the container lid 702 is constructed of a non-metallic material (or where it would be beneficial to utilize a suction cup device), the assembly 700 can include one or more configurable suction cups for picking up the container lid 702.

[0124] In some situations, hazardous waste materials can be transferred to the container through an overhead fill port, which can be positioned above the container opening. The fill port can be configured to dispense the materials into the container. When the fill port stops dispensing waste, the assembly 700 can pivot the drip tray 782 to a position adjacent the container opening to catch any excess or surplus material that spills from the fill port.

[0125] In some embodiments, the drip tray 782 can have a shape similar to the annular weight 750 or the container lid 702. By catching excess or surplus material from the fill port, the drip tray 782 can be configured to prevent the excess material from contaminating the exterior surface of the container or the container lid 702.

[0126] In some embodiments, the drip tray and the annular weight can be configured to be substantially concentric with one another. For example, the drip tray and the annular weight can be substantially circular in shape and positioned such that the center point of the drip tray and the center point of the annular weight are aligned.

[0127] In some embodiments, the drip tray 782 can have a shape or size that is approximately the same as the shape or size of the annular weight 750 or the container lid 702 .

[0128] In some embodiments, the annular weight 750 can be a ring-shaped weight having a hollow central region. In some embodiments, the drip tray 782 can be positioned approximately within the hollow central region of the annular weight 750.

[0129] In some situations, solid waste contained in smaller containers, bags, or other compacted debris can be placed into a container that is sealed with the apparatus embodiments described herein.

[0130] In some embodiments, when the annular weight is positioned on top of the container lid, the annular weight can apply a sealing force to the interface between the container lid and the container opening. The container lid can then be attached to the container opening, and the socket tool can be extended onto the closure assembly. The socket tool can rotate the clamp bolt of the closure assembly 708 to tighten the clamp ring around (i) the periphery of the container lid and (ii) the upper rim of the container opening.

[0131] In some embodiments, the container filled with waste material is rotated on a turntable to align the clamp bolt of the closure assembly with a socket extending into the clamp bolt, where a socket tool can rotate the clamp bolt to a predetermined torque that tightens the clamp ring around the periphery of the container lid.

[0132] In some situations, the annular weight may be removed from the container lid after the container lid has been secured to the container opening.

[0133] Referring to Figure 8, this illustrates a method 800 for assembling a lid assembly for a container lid according to an embodiment of the present disclosure. The lid assembly can include features such as those described in this disclosure and illustrated with reference to Figures 3-7. In some embodiments, the operations of method 800 can be performed by a technician assembling an embodiment of the lid assembly described in this disclosure. In some embodiments, the operations of method 800 can be performed at least in part based on the operation of an assembly device.

[0134] For ease of explanation, the operations of method 800 of Figure 8 will be described with reference to Figure 4B. In some embodiments, the operations may include a sequence of operations including inserting clamp bolt 424 into unthreaded lug 422b, engaging a jamb assembly with clamp bolt 424, and threading the clamp bolt into threaded lug 422a so that the bolt head of clamp bolt 424 is positioned proximal to unthreaded lug 422b. To describe some embodiments, reference will be made to method 800 of Figure 8.

[0135] In step 802, the operation includes inserting the clamp bolt 424 through the unthreaded lug 422b. The unthreaded lug 422b can be secured to a first open end of an open-loop clamp band, such as the clamp ring 420. In some embodiments, the clamp bolt 424 can have threads along its shaft. Because the unthreaded lug 422b does not have threads, inserting the clamp bolt 424 through the unthreaded lug 422b can include pushing the clamp bolt 424 through the unthreaded lug 422b. Inserting the clamp bolt 424 through the unthreaded lug 422b may not require rotation of the clamp bolt 424.

[0136] In step 804, the operation includes engaging the clamp bolt 424 with a jam assembly. In some embodiments, the jam assembly includes a pair of jam nuts 428. The pair of jam nuts 428 can be engaged with the clamp bolt 424 by threading the clamp bolt 424 onto the pair of jam nuts 428. As described herein, the jam assembly can be secured between the threaded lug 422a and the unthreaded lug 422b along the clamp bolt.

[0137] In step 806, the operation includes threading a clamp bolt 424 into the threaded lug 422a, which may be secured to the second open end of the clamp ring 420. Depending on the direction of rotation of the clamp bolt 424, the clamp ring 420 may move from an open position to a closed position to secure the container lid to the container opening, or from the closed position to an open position to allow the container lid to be removed from the container opening.

[0138] In step 808, the operation includes securing the jamb assembly in a calibrated position along the clamp bolt 424. The jamb assembly may be positioned between the threaded lug 422a and the unthreaded lug 422b.

[0139] In some embodiments, securing the jam assembly includes applying a torque to each of a pair of jam nuts toward the other to secure the jam assembly in a calibrated position along the clamp bolt. Engaging the clamp bolt 424 with the jam assembly allows the clamp bolt 424 and the pair of nuts 428 to rotate as a unitary structure as the clamp bolt 424 rotates to transition between the open and closed positions of the open-loop clamp band.

[0140] The jam assembly is secured to the clamp bolt 424, which allows the clamp bolt 424 and jam assembly to be of one piece, eliminating the need for a technician to rotate a jam assembly (e.g., a pair of jam nuts fixed in calibrated positions along the clamp bolt 424) during the operation of moving the clamp ring 420 from the open position to the closed position. This may be in contrast to the embodiment described in FIG. 2. Recall from FIG. 2 that the single lock nut 126 may not be fixed in any particular position along the clamp bolt 424. To move the clamp ring from the open position to the closed position, the technician may need to perform a repetitive sequence of rotating the lock nut 126 and clamp bolt 124. Because the clamp ring 120 is biased toward the closed position, the unthreaded lug 122b may be biased toward the single lock nut 126.

[0141] In some embodiments, a calibrated position along clamp bolt 424 may be predefined or specified as the position when jam nut 428 is adjacent threaded lug 422a while the open-loop clamp band is in the closed position. The calibrated position along clamp bolt 424 may be a function of the diameter of the open-loop clamp band, the diameter of the container lid, or the diameter of the container opening.

[0142] The jam assembly embodiments described in this disclosure include a pair of nuts, each of which is torqued toward one another. When each of the pair of nuts is torqued toward one another, the pair of nuts can be locked in place along the clamp bolt 424. Because each of the pair of nuts 428 in FIG. 4 can have a thickness profile that is thinner than the thickness profile of the single lock nut 126 in FIG. 1, the embodiment including the pair of nuts 428 locked along the clamp bolt 424 results in a feature that does not void prior certification testing or regulatory approvals for the container, container lid, or lid assembly associated with sealing such a container.

[0143] In some embodiments, the operation can include securing a spacing device between the unthreaded lug 422b and the jamb assembly that maintains the position of the bolt head relative to the unthreaded lug 422b. In some embodiments, the spacing device can be a cotter pin 460 (FIG. 4B), a Belleville washer 570 (FIG. 5), or a wedge 672 (FIG. 6), among others.

[0144] In some embodiments, securing the distancing device can include drilling an aperture in the shaft of the clamp bolt at a location between the secured jamb assembly (e.g., the pair of secured nuts 428) and the unthreaded lug 422 b. The operation for securing the distancing device can include inserting a cotter pin 460 into the drilled aperture to position the pin between the jamb assembly and the unthreaded lug 422 b.

[0145] In some embodiments, method 800 can include rotating clamp bolt 424 in a direction that unscrews it from threaded lug 422a to position the open-loop clamp band in the open position. By assembling the lid assembly (e.g., method 800) so that the open-loop clamp band is in the open position, the clamp band can be fed to a container sealing station and be readily available for positioning at the interface between the container lid and the rim of the container opening.

[0146] The terms "connected" or "coupled" can include both direct coupling (where two elements coupled to each other are in contact with each other) and indirect coupling (where at least one additional element is positioned between the two elements).

[0147] Although the embodiments have been described in detail, it is to be understood that various changes, substitutions, and alterations can be made therein without departing from the scope of the present disclosure. Moreover, the scope of the present disclosure is not intended to be limited to the particular embodiments of the process, machine, manufacture, composition of matter, means, methods and steps described in the specification.
