ABSTRACT:
An improved self-supporting paper carton of the gable-top type is disclosed having formed from a paper blank therefor with a detachable tearaway portion, a carton, which upon being spent, may be readily collapsed by fully opening the top and removing a tear strip together with the removable or tearaway portion of the carton blank. The tear strip is an assemblage bonded together having a zip tab or the actual tear strip adhered to an inner lining layer which, in turn, is adhered to the removable portion of the carton blank. The tear strip assembly is inserted into a cavity in the carton blank at the lower edge of the erected self-supporting paper carton and is dimensioned so that the transverse dimension of the tear strip is greater than that of the removable portion. After insertion, the tear strip assembly is compressed and the inner lining layer is then in conformal relation with exterior surface of the removable portion and with the perforations therebeyond. The conformance of the inner lining layer ensures a leak proof seal about the tear strip assembly. For packaging display purposes, a cover portion is provided of similar material to the face of the carton to provide for continuous printing of the carton graphics without substantial interruption by the tear strip installation.
