ABSTRACT:
A spiral wound can is described in which the body of the can is made up of a relatively heavy fiberboard base or body layer lined within by an oil and moisture impermeable barrier formed from a laminate of aluminum foil and paper. The heavy base layer includes a helically extending separation line or butt joint bonded together by the liner and a reinforcing tensile element in the form of a reinforcing strip. A discrete label covers the reinforcing strip and the body stock and is bonded to the body stock by at least two broken or unbroken lines of adhesive on opposite sides of the reinforcing strip. A circumferentially extending collar cut is made through both the label and the reinforcing strip to facilitate their removal. In one form of the invention, the reinforcing strip is bonded more strongly to the label than to the body and is removed when the label is removed. In another form of the invention, the label is not bonded to the reinforcing strip and is removed first. The reinforcing strip is in the second form provided with an adhesive free area under one corner which defines a lifting tab allowing it to be lifted manually and removed.
