Spiral wound can with provision for printing lower side of label
First Claim
1. An easily opened fiber can for food products, said can comprising,a. a helically wound body stock layer formed from an elongated strip of flexible sheet material having its side edges abutted against one another to form a helically extending butt joint defining a separation line adapted to part when the can is opened,b. a moisture resistant helically wound inner liner against the inside surface of the body stock layer, the liner being bonded to the inner surface of the body stock layer,c. a label strip wound helically over the body stock layer and being bonded thereto by two relatively narrow adhesive strips, one strip extending along substantially each side edge of the label strip,d. a relatively wide adhesive free area extending helically on the inner surface of the label strip between the relatively narrower adhesive strips and the adhesive strips and the adhesive free area being of a width of over half of the label strip width,e. printed indicia applied to the adhesive free area on the inner surface of the label,f. one of said two adhesive strips on the edge of the label being bonded over the separation line and having a width less than about one fourth the width of the label but sufficiently wide to hold the separation line together prior to removal of the label,g. the separation line being located between about 10 percent and 20 percent of the way from one edge of the label strip to the opposite edge of the label strip,h. means to facilitate lifting a portion of the label so that it can be peeled back and removed,i. the removal of the label causing the separation line to be weakened sufficiently to allow the can to be opened along the separation line, and

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 stock layer lined within by an oil and moisture impermeable barrier preferably formed from a laminate of aluminum foil and paper. The base body layer includes a helically extending separation line or butt joint bonded together by the liner and label which is bonded to the body stock by at least two broken or unbroken spaced apart strips of adhesive one of which is aligned over the butt joint and one of which is spaced from the butt joint. A circumferentially extending collar cut is made through the label near the can end to facilitate its removal. Printed indicia is located on the underside of the label between the strips of adhesive.
