ABSTRACT:
A paperboard carton is formed from a single blank of generally rectangular shape which is cut and scored along lines which provide corner panels at the four corners and middle panels separated from the corner panels along one pair of opposite sides of the blank by two laterally spaced pairs of two laterally spaced cut lines connected at their inner ends by an angularly directed cut line, and along the other pair of opposite sides of the blank by two laterally spaced pairs of two laterally spaced score lines which define between them an angle corner panel. The inner ends of the middle panels are defined by score lines which, together with the angle cut lines, define the peripheral margin of a central bottom panel. The middle panels form the ends and sides of the carton. In one specific embodiment, each of the pair of opposite middle panels defined by the spaced pairs of cut lines is provided with a score line which extends parallel to the adjacent cut line and terminates at its inner end at the corresponding end of the angular cut line, whereby the portion of the blank between the last mentioned score and cut lines forms a reinforcing angle corner panel.
