Patent

CA 2628994

A lid for a container having a built-in opening feature comprises a flexible laminate comprising an upper layer and a lower layer, a pair of radially spaced concentric lines of weakness being formed in the upper and lower layers, respectively, wherein the upper and lower layers in an annular region between the lines of weakness are readily peeled apart, and wherein the upper and lower layers outside the annular region are laminated together with an adhesive providing a bond with a greater peel strength than that required to separate the layers in the annular region. An integral strap is formed in the upper layer by a U-shaped cut line. A distal end of the strap opposite from the two ends of the cut line is within an adhesive-free region of the laminate. The ends of the cut line are in an adhesively laminated area of the laminate.
