Abstract: A container includes an end wall having a rivet and a frangible score line that defines a curved tongue shaped panel. The frangible score line terminates at each end substantially on a radial line extending from a lever mounting hole formed within the curved tongue shaped panel. A tab is riveted to the lever-mounting hole to act as second-degree lever. The tab has a first actuating point extending toward the distal looping portion of the frangible score line. The tab has a fulcrum portion extending opposite to the first actuating point and terminating within the curved tongue shape. Lifting of the first actuating point pulls upward on the curved tongue shaped panel at the distal looping portion imparts a shear force of the frangible score line to initiate upward rolling of an extended portion of the curved tongue shaped panel.

Abstract: A pop top lid for cylindrical fluid containers is disclosed. The lid includes an end shell with a scored line defining a tear panel, a stay-on tab assembly, and a rivet for attaching the assembly to the shell. The stay-on tab assembly features a pocketed tang with a central portion containing a pivot hole for the rivet. The assembly includes a top cover and bottom plate, spaced apart by a gap on the leading edge. An aperture point is connected to the pocketed tang and can be rotated. A shearing edge is attached to the central portion and extends radially behind the aperture point. In an embodiment, the bottom plate is embossed to facilitate sliding of the shearing edge under the end shell wall when the pocketed tang is rotated, achieving a resealing clamp action by securely placing the embossed shape into the tear panel opening.

Abstract: A pop top lid enables opening and closing of a top opening in a cylindrical fluid container such as a beverage can. an enclosing a top opening in a cylindrical fluid container. A pocketed tang of a stay-on tab assembly pivots about a central rivet on an end shell of the pop top lid. During lifting and rotation of the stay-on tab assembly, an aperture creation point begins to shear a scored line to remove a tear panel from an end shell of the beverage can. directing the tear panel between a top cover and a bottom plate of the pocketed tang. A flange of the bottom plate assists in removal of the tear panel by being directed into a panel opening left by the tear panel directing the tear panel into the tear panel capturing pocket when the stay-on-tab assembly is rotated in a first direction of rotation.

Abstract: A pop top lid encloses a cylindrical fluid container. The pop top lid includes an end shell having an off-center scored line defining a tear panel; and a stay-on tab assembly riveted through a central portion to the end shell for rotation. An aperture point is attached to a central portion and rotatably positioned proximate to an inner edge of the scored line. A shearing edge is attached to the central portion and radially extending behind the aperture point. An actuator portion is attached to the central portion opposite to the aperture point, is liftable as a first-degree lever to form an aperture at the scored line with the aperture point, and is rotatable to insert the shearing edge into the aperture shearing the scored line to remove the tear panel from the end shell.

Abstract: A flip-up pop-tab in which a partially detachable portion of a lid of a can is separated from the can and hinged away from the opening created in the lid is described.
