摘要:
A domer station having a domer assembly, a housing assembly, and a stacked piston assembly is provided. The domer assembly is movably disposed within a domer body passage located in the housing assembly and structured to move between a forward, first position and a retracted, second position. The stacked piston assembly includes a plurality of pistons, preferably three pistons, disposed in series and a pressure supply. The pistons are disposed behind the domer in pressure chambers. The pistons have a constant pressure applied thereto and are biased towards the domer. The pistons are, however, each restrained by a stop and do not contact, or operatively engage, the domer when the domer is in the domer first position.

A tab is provided, which includes a body having first and second opposing ends, a nose portion disposed at or about the first end of the body, a lift portion disposed at or about the second end of the body of the tab, and a rivet receiving portion disposed proximate the nose portion. The rivet receiving portion includes a generally planar portion, a rivet hole having a perimeter, and an upturned portion extending upwardly from the generally planar portion about the perimeter of the rivet hole. The upturned portion reinforces the rivet hole and has an arcuate cross section profile. An integral rivet extends through the rivet hole and is staked to affix the tab to a can end. The upturned portion is devoid of any corners or edges both before and after the integral rivet is staked.

A method of lining container closures is provided. The method includes providing a liner machine base including a number of fluid dispensing apparatus fixed in a stationary position on the base, conveying a plurality of container closures to the fluid dispensing apparatus using a conveying assembly, manipulating each of the container closures with respect to a corresponding one of the fluid dispensing apparatus as the fluid dispensing apparatus remains stationary and dispenses a sealant, lining a plurality of the container closures with said sealant, and, discharging the container closures from the liner machine.

A can bodymaker ram assembly is provided. The ram assembly includes an elongated, generally hollow ram body and a tension assembly. The ram body includes a proximal end, a medial portion, and a distal end. The tension assembly includes an elongated support member. The tension assembly support member includes a proximal end and a distal end. The tension assembly support member is substantially disposed within the ram body with the tension assembly support member proximal end coupled to the ram body proximal end, and the tension assembly support member distal end coupled to one of the ram body medial portion or the ram body distal end.

A tab is provided for a can end. The can end includes an end panel and a scoreline defining a tear panel in the end panel for providing an opening in the can end. The tab includes a body having first and second opposing ends, a nose portion located at or about the first end, a lift portion located at or about the second end, and a rivet receiving portion disposed proximate the nose portion. The rivet receiving portion includes a rivet hole. A first rivet extends outwardly from the end panel and fastens the rivet receiving portion of the tab to the can end. A second rivet extends outwardly from the end panel to cooperate with a portion of the body proximate the lift portion.

A rotating tab is provided. The tab includes a body having a first end and a second end disposed opposite and distal from the first end, a nose portion located at or about the first end of the tab, a lift portion located at or about the second end of the tab, and a rivet receiving portion disposed proximate the nose portion. The rivet receiving portion includes a rivet hole. A rivet extends through the rivet hole and is staked to fasten the rivet receiving portion of the tab to a can end. The body of the tab is structured to be rotated about the rivet to align a portion of the tab with a secondary scoreline in the can end. A portion of the tab is structured to be depressed to sever the secondary scoreline to vent the can end.

A can end includes a severable panel, a peripheral scoreline, an opening mechanism such as a pull tab, a rivet coupling the pull tab to the severable panel, and a rivet base scoreline in the public side of the severable panel. The rivet base scoreline includes an arcuate head portion, first and second arm portions extending from the arcuate head portion, and first and second ends. The base of the rivet has a radius of curvature forming an intersection between the stem of the rivet and the public side of the severable panel. The arcuate head portion of the rivet base scoreline is contiguous with the radius of curvature.

A linear liner machine includes a base. A plurality of fluid dispensing apparatus such as, for example, sealant guns, are fixed in a stationary position in a linear configuration on the base. A conveying assembly such as, for example, a conveyor belt, conveys container closures to the sealant guns. A manipulation mechanism such as, for example, a number of motors and at least one wheel member, manipulate (e.g., rotate or spin) each of the container closures with respect to a corresponding one of the sealant guns as it dispenses a sealant to line the container closures. Accordingly, the liner comprises a plurality of independent lining stations, wherein operation of a number of said independent lining stations can be stopped while the remaining independent lining stations continue to operate to line the container closures. An associated method of lining container closures is also disclosed.
