A dough package is described that comprises a fiber can containing dough in which the can wall is composed of a body layer of kraft paper having a helically disposed butt joint defined by its mating side edges to which is releasably bonded a relatively thin lightweight label. The label is releasably bonded to the underlying kraft paper by means of a peelable adhesive layer which functions in one of two ways. In the first, the adhesive functions as a releasable layer interposed between the body layer and the unexposed surface of the label. This layer is released from the label and remains in place when the label is peeled back. In the second method the peelable adhesive layer ruptures or splits as the label is lifted although a small fraction e.g. 10% of the surface kraft fibers may be pulled out when the label is removed. The term 'peelable adhesive' herein refers both to adhesives that split and those that separate from the label when the label is lifted.

Fiber can dough package with kraft paper body and peelable label

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.

Spiral wound can with provision for printing lower side of label

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.

Spiral wound can having discrete label and reinforcing elements

A fiber can is described which includes a body composed of a relatively thin liner and a much heavier sheet of body stock covered by a temporary reinforcing sheet or inner label which is enclosed within a display label that encircles the container to provide at least one spirally wound convolution so that the display label partially overlaps itself at least enough to cover the temporary reinforcing sheet and can be removed without disturbing the temporary reinforcing sheet. The container can be used for a variety of products such as fresh dough and other foods, juices, lubricating oils, etc. A circular cut or tear strip is provided to facilitate removal of the display label and in some cases the opening of the container.
