ABSTRACT:
A container has a tubular sidewall wall member having a coating of thermoplastic material on the inner surface thereof and a bottom member having a coating of thermoplastic material on the upper surface thereof. The bottom member has a central portion and a continuous skirt extending downwardly from the periphery of the central portion. The lower portion of the skirt is thermally bonded to the sidewall member while the upper portion of the skirt is free of any bond to the sidewall member. The bottom margin of the sidewall member can be curled inwardly to form a rolled rim to improve the impact resistance. In one embodiment the sidewall blank can have a coating of adherence-preventing material in the area which would be contiguous to the upper portion of the skirt. In another embodiment the upper portion of the skirt can be coated with an adherence-preventing material.
