<p>A single paperboard blank includes at least three side walls (14, 16, 18, 20) and a pair of support panels (28, 30), with a first of the support panels (30) being foldably joined (40) to one of the side walls (18), and a second of the support panels (28) being joined to another of the side walls (20). A first transverse perforation line (36) is extended completely across a width of one of the support panels, the first perforation line being spaced from the joined side wall to define a coupon portion (34) of the one support panel and to permit removal of the coupon portion by tearing the one support panel completely transversely along the perforation line. The support panels are foldably joined by a second transverse perforation line (38) spaced from the first perforation line, the coupon portion thus being removable by tearing along both perforation lines. 3. End flaps (24) are foldably attached (24sl) to end edges of the side walls.</p> |
