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.

An improved container for use in holding oxygen sensitive contents is provided. The container comprises a body having an open end sealed with a metal closure. The metal closure includes a metal structural layer, a polymeric interior coating layer and an oxygen scavenger layer interposed between the metal structural layer and the polymeric interior coating layer.

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 lid for a metal container able to contain a substance, includes a closing cap defined by at least one incision or pre-cut line, able to allow the closing cap to be lifted and at least partly torn; an opening lever disposed astride the incision line and comprising a front fulcrum end and an intermediate region provided with a flexible tongue attached to the closing cap; a mechanical connection located in proximity to the incision line, configured to mechanically attach the flexible tongue to the closing cap and configured to cooperate with said flexible tongue; the incision line having at the front, in the zone where the closing cap starts to be lifted and torn, a portion protruding outward, toward the front fulcrum end of the opening lever; and the protruding portion having, on both sides, segments of the incision line which move away from said mechanical connection element as far as respective deformation zones, caused by compression of the incision line.

A closure body (40) is provided for installation with a liner membrane (52) on a container (44). The closure body (40) has a peripheral portion (74) for being mounted on the container (44) around an access opening (48), and a separable portion (82) that (i) is disposed laterally inwardly of the peripheral portion (74); (ii) is initially connected to the peripheral portion (74) by at least one frangible connection (86); and (iii) can be separated from the peripheral portion (74) upon breaking of the at least one frangible connection (86).

A vented metal can end is provided. The can end includes a tab and a tab rivet. The can end includes an outer score and a vent score. The vent score is formed in the end wall and located beneath the nose of the tab. The vent score is positioned such that the tab rivet is located between the vent score and the center point of the end wall and the vent score is also located between the outer score and the tab rivet.

A food or beverage container having a body portion or an end portion that includes a metal substrate with a coating composition disposed thereon. The coating composition includes a water-dispersible acrylic linear block copolymer made by surfactant-free heterogeneous radical polymerization (SFHRP). The block copolymer imparts a desirable combination of flexibility and corrosion resistance to the coating composition, and the substantial absence of surfactants during polymerization contributes to other desirable properties including good blush resistance.

An opener used to open the cans is shaped as an eating utensil, and may be used to open the can or to remove the cover of the can, as well as for consumption or use of the contents of the can. The eating utensil has a handle and a head shaped as a knife, spoon, fork or a combination of a spoon and a fork. The utensil may be manufactured separately from the can and the cover and is thus a pre-fabricated element for attachment to the can cover, such as in the same or similar manner as existing openers, e.g. on the external surface of the can cover using a rivet or welding.
