ABSTRACT:
A box having a container space for retaining box contents is provided. The box is constructed of a foldable sheet material. The box includes first and second side panels, first and second edge panels, and first and second end flaps. All flaps and panels are foldable about associated fold lines to effect a box having sides and seal ends which together define the container space. A removable strip portion is provided on either an end flap or an edge panel to provide access to the container space. The removable strip portion is defined by interior and exterior partial cuts scored into the foldable material, including a plurality of aligned interrupted exterior cuts that are disposed for an extent coincidentally with an associated fold line. The removable strip portion thus constructed helps ensure folding of the associated flap or panel about the intended fold line while maintaining the strength and integrity of the folded edge.
