Abstract: A non-circular can end for a container having walls which form an opening includes a corner-mounted pull tab opener secured to a severable panel portion by an integral rivet. The corner-mounted opener facilitates easy opening of the can end. A pair of generally parallel bead recesses on either side of the integral rivet stiffen the severable panel portion in order to facilitate bending of the panel aft of the rivet to easily open the can end. The severable panel optionally further includes a mustache-shaped scoreline to reduce the amount of force required to lift the opener. Tooling and a conversion press for converting shells into the non-circular can ends are also disclosed.

Abstract translation: 具有形成开口的壁的容器的非圆形罐端部包括通过整体式铆钉固定到可分割板部分的拐角安装的拉片开启器。 角安装的开启器有助于容易地打开罐头端部。 一体式铆钉的任一侧上的一对大致平行的胎圈凹槽加强了可分割的面板部分，以便于铆钉的后面弯曲以容易地打开罐端部。 可分开的面板可选地进一步包括胡须形刻痕，以减少抬起开启器所需的力量。 还公开了用于将壳转换成非圆形罐端的模具和转换压力机。
