ABSTRACT:
A composite container is disclosed that includes a helically-wound label layer which contains a line of perforations that extends circumferentially adjacent and spaced from a metal end closure member, thereby to define a line of tear along which the label layer may be torn from the container. By the provision of the perforated tear line, the requirement of a collar cut in the container is avoided, thereby permitting the use of a thinner fibrous body wall layer. Preferably the line of perforations is discontinuous to define an imperforate portion of the label layer which is bonded in straddling relation across the helical butt joint contained in the fibrous body wall layer.
