Abstract: A beverage can cap member (16, 100) is configured so that its exterior surface (28) extending radially inwardly from the rim (18) or rim forming portion (140) is substantially flat or continuous, or has a slight curve from a position adjacent from the rim (18) or rim forming portion (140). The cap member (16, 100) may have a countersink (160) which is filled with a filler material including a curable adhesive, an insert (180) of a natural or synthetic material or the like. The filler material increases the structural strength of the cap member (16, 100) to an extent that it can be made of a relatively thinner material and still complies with the minimum peaking pressure of the industrial standard.

Abstract: A beverage can lid with an easy opening feature comprises a scored lid, having a pull tab affixed to the lid by a rivet and an initial contact point on the lid which is pushed downward as the score line breaks at the puncture point adjacent the rivet. In the invention, the contact point is positioned in close proximity to the rivet to minimize the required lifting force, which is in proportion to the distance between the initial contact point and the rivet. Further, the puncture point is positioned close to the initial contact point so that the lifting force is also reduced. In one embodiment, the scoring radius at the puncture point is quite sharp so that the force required to break the seal at the puncture point is reduced. Also the gap between the puncture point and the end of the scored line is minimized to facilitate opening the lid. Furthermore, the pivot line is moved closer to the contact point to reduce the lifting force.

Abstract: A can cover with a stay-on tab, in which it is very easy to insert a finger between the stay-on tab 17 and the upper surface of the can cover.
