A method of making a can end, which includes a recessed panel defined by an upwardly extending chuck wall, a peripheral scoreline disposed in a public side of the panel proximate to the base of the chuck wall, a tab fastened to the panel by a rivet, includes the step of employing tooling to form a pressure resistance bead extends around the panel inboard of the peripheral scoreline and outboard of the rivet. The tooling forms a saw tooth panel formation proximate to the pressure resistance bead inboard of the pressure resistance bead. Among other benefits, the pressure resistance bead and saw tooth panel formation created by the tooling and method combine to resist wrinkling or other undesired deformation of the can end.

The disclosure describes embodiments of an apparatus including a first gas chromatograph including a fluid inlet, a fluid outlet, and a first temperature control. A controller is coupled to the first temperature control and includes logic to apply a first temperature profile to the first temperature control to heat, cool, or both heat and cool the first gas chromatograph. Other embodiments are disclosed and claimed.

A progressive die manufacturing method for producing pull tabs with raised lift ends for beverage containers utilizes an ear carry process, producing tab blanks from a carrier sheet fixed by carrier strips at attachment points. At a tab station, blanks are formed into pull tabs with specific features including a nose, rivet receiving portion, lift portion, and preferably a finger hole. A lift station creates deformations elevating the lift portion relative to a highest continuous surface of the pull tab, prior to any deformations or bends. The carrier strips are then cut to release the finished pull tabs. Optional enhancements include an integrated or modular lift station, specific bending angles and distances, and a center bar for indicia application. This method combines the benefits of the ear carry process with improved ergonomics, enhancing user experience while minimizing machinery modifications.

The disclosure relates to a tool with a material layer on one or both sides, said tool having a cutting bell rigidly coupled to an upper forming punch and a drawing cushion coupled to a hold-down device, the upper forming punch and a lower forming punch being movable relative to one another to close the tool, and a first gap present between the cutting bell and the hold-down device when the tool is closed, and an end stop formed by the lower forming punch for a lower pressure piece that can be moved relative to it, that the sheet metal blank can be clamped between the upper and the lower pressure piece, and that during a relative movement between the lower forming punch and the lower pressure piece, the upper and the lower pressure piece remain in their position relative to one another clamping a sheet metal blank.

An end closure for food and beverage containers provides controlled opening characteristics to prevent the unintentional missiling of a tear panel. The end closure comprises a score line that defines a portion of the tear panel, and the end closure may comprise one or more anti-missile features that inhibit the propagation of a fracture down a score line, which reduces the likelihood that a tear panel will inadvertently detach from the end closure and injure the user or another.

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 shell, a container employing the shell, and tooling and associated methods for forming the shell are provided. The shell includes a center panel, a circumferential chuck wall, an annular countersink between the center panel and the circumferential chuck wall, and a curl extending radially outwardly from the chuck wall. The material of at least one predetermined portion of the shell is selectively stretched relative to at least one other portion of the shell, thereby providing a corresponding thinned portion.

A can end for a two-piece beverage container has a curl positioned about a longitudinal axis which defines an outer perimeter of the can end. A circumferential wall angles downwardly and radially inwardly relative to a radially inner portion of the curl. A strengthening member extends radially inwardly relative to the circumferential wall. A center panel extends radially outwardly from the longitudinal axis towards the strengthening member and has a diameter greater than 87.7% of an overall diameter of the can end. A frangible score and a hinge portion define an openable tear panel in the center panel. A stay-on tab is attached to the center panel and has a nose portion overlying the tear panel opposite a lift end of the tab.
