Abstract: A pop-top can lid is easier to open than conventional lids, and includes a generally horizontally extending can cover plate having a peripheral rim. It also has a scored area medial of the rim. An elongated generally horizontally extending lift tab is pivotally secured to the upper surface of the plate at a pivot point medial of the rim by a rivet or the like. The tab is divided into an elongated lift arm with finger-receiving opening on one side of the rivet and a shorter drive arm on the opposite side of the rivet. The drive arm is directly over the medial portion of the scored area. A bubble integral with the plate extends upwardly therefrom in the scored area and is capable of being inverted by downward finger pressure. Then the drive arm is able to be easily rotated down thereinto, thus automatically raising the lift arm well above the plate surface so that it can easily be grasped by the fingers.

Abstract: A one-piece molded end closure has a pull ring spaced from a main panel having an annular flange extending therefrom. When the end closure is frangible through having score lines formed in the main panel, the pull ring is connected by a tenon adjacent a score point, which is the junction of two score lines and inside of the inner diameter of the pull ring, so that pulling on the pull ring, which is substantially parallel to the main panel, starts rupturing of the two score lines.
