A nesting drum and a method of making the same is provided. The drum comprises a shell which has a necking at the bottom to accommodate a double seam between the shell and the closure. The closure has a raised circular center and a plurality of ribs which re-enforce the shell to resist large loads. '

Nesting drums

A nesting drum and a method of making the same is provided. The drum comprises a shell which has a necking at the bottom to accommodate a double seam between the shell and the closure. The closure has a raised circular center and a plurality of ribs which re-enforce the shell to resist large loads.

Nesting drums-method of making the same

A split ring locking rim assembly for releasably securing a head or cover to a container having a split ring with two ends positioned substantially adjacent to one another with a raised part of eyelet thereon space from one end of the ring to receive a portion of a locking mechanism. The locking mechanism includes a lever shaped so as to align the ring during operation which is pivotally connected to one end of the ring with the other end of the ring pivotally connected to a connecting link which is pivotally connected to the lever. The lever includes a tongue with a raised portion thereon in the form of an eyelet and in operation the lever serves to bring the ring ends together sealing the cover or head to the container while the lever tongue enters the receptacle on the ring with the raised portion on the tongue passing therethrough wherein this raised portion acts as a retaining means for the lever in its closed position while also providing a means for securing a sealing wire.

Split ring locking assembly

A drum with sealed end closures and the method of forming the drum in which a tubular shell is formed to define drum side walls. An end closure is applied to at least one end of the shell with the adjacent peripheral edges of the shell end closure being formed into a circumferentially extending chime with the peripheral edges defining said chime being in abutting surface-to-surface contact and folded to provide a seam with five layers of material of said edges being in a transverse radial direction. The chime is thereafter formed into a reinforced chime folded to provide a seam of predetermined shape with seven layers of material of the edges being in a transverse radial direction and having increased sealing, handling, and strength characteristics while retaining a minimum desired length for the seam.

Seal drum with end closure having reinforced seams

The disclosure is of a closing ring assembly for sealing the cover of a drum type of container. The assembly comprises a split ring, the ends of which are connected by a bolt secured through a pair of bolt clips mounted on the ends of the split ring. The bolt clips comprise tubular members having flared open ends. The clips are positioned in a specific manner to receive the bolt component without interfering with rolling of the drum. In a preferred embodiment, the bolt clips include a threaded retainer member to cooperate with a threaded bolt. The assembly of the invention is advantageous in that it is more economical to manufacture, more secure in use, easier to operate and stronger than prior art closing ring assemblies.

Drum container closing ring assembly

A clamping ring for securing a removable cover on a drum is provided with a closing device having a lever and a latch. The lever is pivotal in a plane parallel to that of the clamping ring from an outwardly extending open position inwardly to contract the ring into a closed position. The latch is pivoted downwardly until its latch finger extends through a slot in the lever finger to place the clamping ring in a sealed position. This sealed position is accomplished by means of a primary lock caused by the interengagement of a hook-tang on the latch finger and bottom surfaces of the lever finger adjacent the slot. A secondary lock is formed by the interengagement of an inwardly projecting tang on the latch finger which also engages with surfaces of the lever finger adjacent the slot.

Clamping ring for removable covers of drums

A method and structure is provided for retaining one or more drums on a pallet. The drum structure is normally in closure sealing the bottom end of the tubular body and either a cover or a closure for the top end of the body. The drum is provided with confining structure on at least one of the upper and lower ends which is adapted to capture a strap for securing the drum to the pallet. The confining structure is such that it facilitates the strapping of each drum of a plurality arranged in a group to a single pallet while capturing the straps and preventing slippage thereof from the drums. The confining structure can be in the form of protuberances or indentations and, in the case of the sealed drum, would be formed in at least the top seam of the drum and, in the case of a drum with a removable cover, can be formed in the clamping ring used to hold the cover on the drum.

Method and structure for retaining shipping drums on pallets

A nestable drum is provided with a tubular shell having a lower section and a top section of increased diameter joined by an integral step located approximately at the shell middle. The larger diameter top section is adapted to conveniently receive the reduced bottom section to facilitate nesting when drums are stacked one upon the other. The step is formed with a series of spaced reinforcing gussets which are adapted to rest on the top end of a lower drum in the stack. The top of the shell is necked-in and possesses a diameter less than that of the top section and is curled outwardly to provide a bead which receives a cover locked in place by a split clamping ring. One form of cover is provided with an indentation which is adapted to receive the bottom closure of a stacked drum to lock it in place and thereby prevent any relative sliding.
