ABSTRACT:
A carton of sheet fibrous material includes a removable access panel having a curvilinear peripheral outline defined by a plurality of spaced linear perforations. The outline comprises a plurality of pairs of associated arcuate segments, the perforations in each arcuate segment of an associated pair being the mirror image of the perforations in the other segment of the associated pair. All of the respective perforations of one of the arcuate segments are disposed at the same predetermined angle relative to the longitudinal axis of the access panel. Each of the pairs of arcuate segments defines a discrete panel section, at least one of the panel sections having a greater resistance to tearing than the other panel sections. The perforations of the panel section of higher resistance to tearing is disposed at a predetermined angle relative to the longitudinal axis of the access panel which is less than the angles to which the perforations of the other discrete panel sections are disposed relative to the longitudinal axis of the access panel. As a result, the access panel, while being readily removable from the carton, includes at least one support section defined by the panel section of higher resistance to tearing, thus protecting the carton from accidental collapse.
