ABSTRACT:
A container blank has a bottom panel with outwardly extending inner and outer end panels which fold up to form double thickness end walls. Two opposed parallel side panels have glue tabs which are affixed to the outer end panels. Each glue tab has a 45-degree angle fold line which allows the side panels to be folded to overlie the bottom panel during shipping. In a covered box where the height of the box h measured vertically exceeds one quarter the length of the end panel and approaches one half the length of the end panels, there is not space available to receive the cover front flap tab within a pocket defined between the end wall and an adhesively attached glue tab, if the glue tabs in front and in back are of equal size. To accommodate the enlarged cover front flap tabs, the front glue tabs may extend a greater distance along the end panels than the rear glue tabs. The rear glue tabs are less than half the length of the outer end panels, and do not extend frontwardly beyond the glue tab fold line. The glue attachment region on the rear glue tabs may thus be located only on the triangular region defined below the glue tab fold line.
