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. The lift arm can then be rotated upwardly to force the drive arm down to break the plate at the score line to fold the scored area down into the can to form a pour opening for the can. Preferably, the raised bubble biases the drive arm up and the lift arm down so that the tab does not rattle, and the lift arm is against the upper surface of the plate, for easier stacking of a plurality of the lids together.
