Patent number: 8490825Abstract: 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.Type: GrantFiled: July 25, 2005Date of Patent: July 23, 2013Inventors: James Reed, Christopher G.

Patent number: 7874450Abstract: A lid for a beverage can possessing excellent characteristics in pressure resistant strength in which a predetermined pressure requirement is ensured by a simple gauging down. An annular groove portion of the can lid is formed to have such cross-sectional shapes that a panel wall portion is connected to a chuck wall radius portion so that a tangential line at a second contact point is vertical with respect to an axial direction of a center panel portion, while a chuck wall portion is connected to the chuck wall radius portion so that a tangential line at a first contact point is inclined to the radially inner side, and a curved portion with a radius R1 is provided at a height h1 from the lowest point of the chuck wall radius portion and bent to the radially outer side.Type: GrantFiled: May 14, 2008Date of Patent: January 25, 2011Assignee: Toyo Seikan Kaishi, Ltd.Inventors: Mamoru Shibasaka, Masaomi Tamura, Hideki Nishimoto

Patent number: 7819275Abstract: A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inclined inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with an inclined lower wall portion of a chuckwall at a junction below the center panel, and the chuckwall has a curved or inclined upper wall portion which connects with an inner wall of the crown. The chuckwall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall. The inclined upper wall portion of the chuckwall extends at an angle greater than the angle of the inclined lower wall portion of the chuckwall.Type: GrantFiled: September 9, 2004Date of Patent: October 26, 2010Assignees: Container Development, Ltd., Ball CorporationInventors: R. Peter Stodd, Jess N. Bathurst

Patent number: 7789261Abstract: A open can end of laminated steel sheet has a score formed thereon by a scoring die. The scoring die has a scoring edge having a sectional shape of an inverted triangle. The scoring edge includes a tip formed of a curve having a radius of curvature of 0.2 mm or more and 0.4 mm or less. Two sides sandwiching the tip are tangent to the curve. A function tan ? of an angle of elevation ? of each of the sides with respect to a surface of the can end is 0.3 or more and 1.0 or less. The resultant a can end being an easy open can end.Type: GrantFiled: November 26, 2004Date of Patent: September 7, 2010Assignee: JFE Steel CorporationInventors: Hiroshi Kubo, Katsumi Kojima, Hiroki Iwasa

Patent number: 7644833Abstract: A can end member for a beverage container is disclosed. The end member has a curl at least substantially defining a perimeter of the can end, a chuck wall extending downwardly and radially inwardly from the curl, and a central panel wall centered about a longitudinal axis. The central panel wall has a product side and a public side. The public side has a means for opening a frangible panel segment. The end member also has a fold joining the chuck wall with the central panel wall. The fold has an opening. A fluid is located adjacent the opening.Type: GrantFiled: September 26, 2005Date of Patent: January 12, 2010Assignee: Rexam Beverage Can CompanyInventors: Timothy Turner, Rajesh Gopalaswamy, Randall G.

Publication number: 20090266850Abstract: A unified assembly of a mounting cup and valve stem assembly for aerosol containers. The mounting cup contains a flat central portion having an inner section extending downward from its periphery. An outer section extends upward from the lower edge of the inner section and abuts the inner section. The inner and outer sections constitute the lower wall. The outer section extends above the flat central portion and ends in a channel which can fit onto the bead of an aerosol container. The flat central portion has at least one hole through it. The valve stem assembly contains a flat circular upper piece having holes corresponding to those in the mounting cup. The holes are the open top ends of chambers for springs and plungers. Valve stems are below the chamber. The lower wall of the mounting cup is crimped to hold the mounting cup to the valve stem assembly.Type: ApplicationFiled: April 28, 2008Publication date: October 29, 2009Inventor: Ronald D. Green

Patent number: 7591392Abstract: 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.Type: GrantFiled: November 1, 2004Date of Patent: September 22, 2009Assignee: Crown Packaging Technology, Inc.Inventors: Martin J.

Publication number: 20090200321Abstract: 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.Type: ApplicationFiled: May 16, 2006Publication date: August 13, 2009Applicant: TOYO SEIKAN KAISHA, LTD.Inventors: Kei Oohori, Kiyotaka Yoshida, Sunao Morishita, Kanji Kuroda, Norifumi Yasuda, Kazuo Ando, Hisashi Katoh
