Patent number: 5069356Abstract: An end panel for an easy open end includes a pull tab fixed to the removable inside portion and a score line having two different defined depths, including a first severing depth passing under the nose of the pull tab and substantially all of the remaining areas except for an area rearward of the pull tab, where the score line extends to a second, shallower temporary retention depth in order to retain the rearward area with the outside portion as the inside portion moves outwardly away from the container during either inadvertent or intentional opening.Type: GrantFiled: November 8, 1990Date of Patent: December 3, 1991Assignee: Automated Container CorporationInventor: Edgar H. Zysset

Patent number: 5052573Abstract: An easy open end employs an enlarged "moustache" score, in which the apex of the outward curves of the score lie outside of the plane of the sides of the pull tab to effectuate a rolling of the metal ribbon between the rivet and the peripheral weakened area, so as to avoid lateral forces which tend to tear the metal along the ribbon.Type: GrantFiled: February 21, 1990Date of Patent: October 1, 1991Assignee: Automated Container CorporationInventor: Edgar H. Zysset

Patent number: 4596342Abstract: Disclosed are easy open containers using pull tabs having rivet holes with not less than eight, nor more than ten sides. A point between any two flats of the rivet hole is aligned with the pull tab nose. The disclosed rivet holes provide good locking characteristics.Type: GrantFiled: July 19, 1985Date of Patent: June 24, 1986Assignee: Automated Container CorporationInventor: Edgar H. Zysset

Patent number: 4538758Abstract: An improved hermetically sealed composite container formed by double-seaming a pair of compounded metal ends to extended length flanges on the opposite ends of a can body so that the compound is bonded to an inner liner on the can body to provide an effective seal. The compound material is placed in the seaming panel and curl area of the metal ends so as to provide a more extensive seal area when the metal ends are double-seamed with the extended flanges on the can body. The extended length flanges provide a considerably greater contact area between the can body inner liner and the metal ends when the metal ends are double-seamed to the can body.Type: GrantFiled: October 8, 1981Date of Patent: September 3, 1985Assignee: Automated Container CorporationInventor: Edwin D. Griffith

Patent number: 4535909Abstract: An easy open pull tab system and method is adapted for use with a container of the type having a weakened score line, the severing of which permits access to the container. A fastener is joined to the container end and spaced from the score line, with a pull tab joined to the fastener through an octagonal hole, the tab having a pull ring extending from the fastener in a direction away from the score line. The pull tab includes a nose portion extending adjacent to the score line to permit the desired severing upon pulling of the pull ring in a direction away from the container end. The tab is formed with a continuous peripheral curl extending along two beams forward to the nose portion, and is provided with only two carrier lugs on opposite sides of the pull ring for use in the manufacturing of the tab. The container end is provided with a crimped ridge designed to abut a flat metal strip through which the fastener is connected to the container, to limit axial rotation of the tab about the fastener.Type: GrantFiled: March 23, 1984Date of Patent: August 20, 1985Assignee: Automated Container CorporationInventor: Edgar H. Zysset

Patent number: 4511299Abstract: An easy open pull-tab container and related method comprises a generally planar end having a line of weakness defining a tear line so that a portion of the end is partially removable, the tear line lying in the plane of the end. A pull-tab is provided for severing the portion along the tear line, with first and second portions of the end wall on opposite sides of, and spaced from the line of weakness, extending underneath the area adjacent the line of weakness and to form blunt, protective shoulders at the line of weakness. The protective shoulders are formed via first and second concentric grooves in the end, the grooves extending below the level of the end to form inner and outer beads, the inner bead extending substantially below the outer bead. A central bead is formed in the end between the first and second concentric grooves, the central head extending above the level of the end.Type: GrantFiled: September 1, 1983Date of Patent: April 16, 1985Assignee: Automated Container CorporationInventor: Edgar H. Zysset

Patent number: 4406378Abstract: A metallic convenience closure for a cylindrical container comprises a panel, an endless score line formed in the panel and defining a central removable portion and a peripheral fixed portion, means forming a part of the fixed portion for attaching a closure to the end of a container to close the end, a manually graspable pull-tab attached to the removable portion of the panel and having a nose portion movable upon lifting of the tab into position adjacent the score line for severing the score line, and stiffening means on the removable panel extending generally parallel to the direction of pull of the pull-tab such that said stiffening means will resist the tendency of the removable portion to bend transversely of the general pull direction.Type: GrantFiled: July 6, 1981Date of Patent: September 27, 1983Assignee: Automated Container CorporationInventor: Edgar H. Zysset

Patent number: 4355759Abstract: An improved composite container, and method of forming same, which incorporates a unique plastic end which is compression molded into bonded engagement with a composite container body. The plastic end is formed from a like material which forms the inner or outer lining on the composite container body so as to form a leak-proof seal between the plastic end and the composite container body.Type: GrantFiled: October 4, 1979Date of Patent: October 26, 1982Assignee: Automated Container CorporationInventor: Ralph G.
