Abstract
An easily-opened can lid includes a cover ring having an outer edge and an inner edge. The inner edge folds inwardly to form an annular flange surrounding a lid opening. A tear-off portion aligned about the annular flange has a lateral area covering the entirety of the lid opening such that the lid opening is smaller than the tear-off portion. An attachment tab is secured at a location on the lateral area of the tear-off portion and an opening ring is secured to that attachment tab. An outside edge of the tear-off portion can be aligned with the inside edge of the cover ring so that the annular flange is entirely covered by the lateral area of the tear-off portion. Heat sealing coatings can be applied to the lateral area of the tear-off portion on a bottom side thereof and to the top side of the annular flange to secure the cover ring to the tear-off portion.
