Abstract
A container lid is formed as a flexible laminate of an upper layer and a lower layer and having a built-in opening feature. A pair of radially spaced concentric lines of weakness are 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. The upper and lower layers in an annular region between the lines of weakness are readily peeled apart. 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.
