Abstract:
1. A lid for sealing a container, the lid comprising: a flexible laminate comprising an upper layer and a lower layer, a pair of radially spaced concentric lines of weakness each comprising a closed loop being formed in the laminate, an outer one of the lines of weakness being formed in the upper layer and an inner one of the lines of weakness being formed in the lower layer, wherein the upper and lower layers in an annular region between the lines of weakness are readily separated by exerting a peel force on the upper layer, 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 the peel force required to separate the layers in the annular region; wherein the upper layer is cut along a generally U-shaped cut line to define a tab, the tab having a distal end for grasping and an opposite end defined by ends of the cut line; the adhesive being absent in an adhesive-free region underlying the distal end of the tab so that the distal end can be lifted from the lower layer, and wherein the ends of the U-shaped cut line defining the tab are located outside the adhesive-free region in an adhesively laminated area of the laminate.
