ABSTRACT:
A cover for a can comprising a multi-layer base of aluminum foil between heat-fusible resin layers and an overlying laminated resin layer. The outer resin layer has an inner section and a surrounding outer section separated by a gap through which the multi-layer base is exposed. The gap is smooth and continuous, that is, does not have a point, so that the inner section can be leveraged into the multi-layer base and the stress is uniformly distributed over a wide area of the multi-layer base.
