Abstract
Abstract A container blank comprises a one piece sheet of paper board, fibre board and similar material which includes a central bottom forming panel having rounded corner portions formed by score lines which separates each side and end portion of the bottom from substantially coextensive side and end flaps formed on the exterior of the score lines. Each rounded corner is provided with a rounded slot cutout which defines a rectangular securing tab or flap joined at the center of the rounded corner to the bottom panel. The blank is erected into a container by orienting the side and end flaps upwardly by bending them about the score line connections to the bottom panel and then by bending the rectangular flap upwardly to close the slot formed between adjacent ends of the side and end panels. The side and end panels are either abutted at the rounded corners or spaced apart, but in each case they are overlapped by the securing flaps. The complete container is held in a rigid erected condition by stapling the corner securing flaps to the associated side and end panels.
