Easy-open folding carton and method for manufacturing same

Abstract

An easy-open folding carton having a manufacturer's joint in which two panels are joined by an adhesive. One of the two panels includes a plurality of punch scores. The other panel is coated with a coating and includes a plurality of uncoated “knock-outs” that are aligned with the punch scores. The adhesive is disposed between the two panels in alignment with the knock-outs and punch scores. The panel that includes the punch scores is preferably coated, except for an uncoated stripe that extends through the approximate center of the punch scores. The present invention also provides a method for manufacturing a carton including the steps of (a) forming a carton blank having an adhesive panel and a first panel, (b) forming punch scores in one of the adhesive panel and the first panel, (c) coating the other of the first panel and the adhesive panel leaving a pattern of uncoated knock outs positioned to align with the punch scores in the assembled carton, (d) folding the blank into a carton, and (e) securing the adhesive panel to the first panel by an adhesive disposed between the punch scores and knock outs.
