A can container includes a can barrel and a can bottom; the can bottom includes a dome part which is concaved toward an inner side of the can container along a direction of a can axis at a center, and also includes an annular convex part which projects toward an outer side of the can container so as to shape an annular support part on an outer periphery of the dome part: and the dome part has a central dome part which is positioned on the can axis and has a set radius of curvature, and an outer peripheral dome part which is shaped continuously on an outer side of the central dome part, has a center of curvature positioned on the can axis, and has a radius of curvature smaller than the radius of curvature of the central dome part.- - -

METHOD AND APPARATUS FOR PRODUCING A ROLLED CURL ON AN OPEN END OF METAL CONTAINER

A method for forming a curl on an open end of a metal container, for adapting the metal bottle to be closed by a cap, comprising in sequence: inserting the open end of the metal container into a powered first curler roller housing, wherein the first curler roller housing houses a set of first curler rollers, to deform the open end by turning it outwardly so as to obtain a first stage curl; inserting the open end of the metal container having the first stage curl into a powered second curler roller housing, wherein the second curler roller housing houses a set of second curler rollers, to further deform the open end and first stage curl by turning them outwardly and/or curling them so as to obtain a second stage curl; inserting the open end of the metal container or bottle having the second stage curl into a powered third curler roller housing, wherein the third curler roller housing houses a set of third curler rollers, to further deform the open end and second stage curl by turning them outwardly, curling them and/or compressing the second stage curl radially and/or longitudinally downward towards a bottom of the metal container so as to obtain a third stage curl.

METHOD AND APPARATUS FOR CLAMPING A CONTAINER DURING PROCESSING OPERATIONS
20230166316 · 2023-06-01 ·

A device for inhibiting rotational motion of an article to be processed comprises a pressure plate assembly including a generally ring-shaped guide assembly. The guide assembly has and at least two guide pins extending from a first side in a transverse direction. The guide assembly further includes at least two resilient devices positioned over a respective one of the at least two guide pins and a container guide having an aperture for receiving an open end of a container moving in a first direction and for aligning the open end with a processing device. The container guide is positioned adjacent to the first side of the pressure plate assembly. At least two resilient devices are configured to be compressed in response to movement of the container guide in a first direction and are configured to decompress in response to movement of the container guide in a second, generally opposite direction.

Aluminum alloy strip with improved surface appearance

The invention relates to an aluminum alloy strip with improved surface optics, which is fabricated via hot and/or cold rolling, and consists of a type AA 3xxx, AA 5xxx, AA 6xxx or AA 8xxx aluminum alloy. The object of proposing an aluminum alloy strip that is suitable for attractive and precious surface optics despite the elevated percentage of alloy constituents is achieved in that, after degreasing, the finish-rolled aluminum alloy strip exhibits an increase in the luminance value L*(ΔL) in relation to the rolled-greasy state of more than 5 while measuring the color of the surface in the CIE L*a*b* color space using a standard illuminant D65 and a normal observation angle of 10°, excluding direct reflection in 45°/0° geometry.

Flange projection control system and method

Embodiments provide a tooling station for forming containers that includes a blank and draw punch configured to blank off a portion of stock from a stock element and draw the portion of stock to form a cup. The blank and draw punch includes a blank and draw punch curved edge disposed between a blank and draw punch inner circumferential wall and a blank and draw punch proximal surface. The blank and draw punch curved edge has a radius of curvature that varies along its circumference. The tooling station also includes a draw-redraw die configured to redraw the cup to form a can having a flange. The draw redraw die includes a draw-redraw die curved edge disposed between a draw-redraw die inner circumferential wall and a draw-redraw die proximal surface. The draw-redraw die curved edge has a radius of curvature that varies along its circumference.

METHOD AND APPARATUS FOR SEALING A METALLIC CONTAINER WITH A METALLIC END CLOSURE
20220347736 · 2022-11-03 · ·

An apparatus includes a tool operable to releasably join a metallic end closure to a metallic container. In one embodiment, the tool is configured to form a thread in the closure and the container. The tool may optionally crimp the closure to the container. Once sealed, the container can be opened by rotating the closure in an opening direction. The closure can subsequently re-close the container by rotating the closure in a closing direction.
