The end protection cells of the container are attached to side reinforcing panels. This reduces the number of steps required to place reinforcing panels in the end wall construction. In the preferred construction the end cell panels are attached to the main body only through the reinforcing panels. In one construction, an additional bellows or gusset panel is provided for additional reinforcement. ## Claims ### Claim 1 A blank for a container comprising a first side panel, a bottom panel, a
