  • Patent number: 8490825
    Abstract: Over the years there have been numerous attempts to improve the can lid oftentimes found on aluminum beverage can lids. The aims have traditionally been to reduce costs and improve performance. These aims have been accomplished through a variety of means, such as creating different formations within the can lid to reduce the amount of metal used while maintaining performance levels. Here, step portions are utilized between the annular countersink and the center panel of the can lid that cause a curvature of the center panel or to simply provide an angled inside wall. These formations, thus, reduce the amount of metal used while maintaining quality and yielding the desired performance.

  • Patent number: 7591392
    Abstract: A can end having a countersink bead, an inclined chuck wall and a strong seam, resists distortion from its circular profile when subjected to thermal processing or when packaging carbonated beverages. This high hoop strength affects the manner in which the can end ultimately fails when placed under extreme abuse conditions, even if buckle pressure performance is within industry specified standards. The can end of the invention has control features introduced which control the failure mode while maintaining specified buckle pressure performance. In one embodiment, the can end has a two part wall and a control feature that comprises expansion of the countersink bead to act as a trigger for local peaking, together with a groove in the chuck wall which prevents the peaking force from being concentrated at a single point which could result in leaking by the production of a pin hole.

  • Publication number: 20090200321
    Abstract: ABSTRACT A square can capable of securing high sealing performance even if a curvature radius of a seamed portion at a seamed corner portion is reduced, enabling a reduction in a countersink depth, reduced in size, having excellent sealing ability and storage efficiency and a method and an apparatus for double seaming the square can. A second seaming roll (55) is guided by a model cam for second seaming having a model cam surface for second seaming formed in such a shape that it is swelled from a model cam surface for first seaming outwards at a corner seamed portion (5). Accordingly, the seaming shape of the corner seamed portion (5) is formed in such a shape that the seaming width thereof at the center of the corner seamed portion is larger than the seaming width of a linear sealed portion (4) and is swelled outwards to absorb an increase in sheet thickness at the corner seamed portion.

  • Patent number: 7497350
    Abstract: A configuration of an outwardly curled portion formed on an opening portion of a metal can, in which both inner and outer faces of a metal sheet forming at least around the opening portion are covered with a resin film, in which the curled portion formed above an inclined face by curling an upper end of a trim end portion so as to confine it inside of the curled portion, as being squeezed in the can radius direction so as to contact its lower end with the inclined face, and in which the metal sheet layers are folded in the can radius direction via the resin films in the most part but except around both upper and lower ends of the curled portion. Accordingly, the trim end portion of in the curled portion can be prevented from getting rusty, and deterioration in the appearance of the curled portion can be avoided. Moreover, the strength of the curled portion is enhanced so that the resistance against the deformation is improved.
