ABSTRACT:
An integral carton blank from which a carton is formed having an end with three upstanding carton walls forming a pair of spaced-apart outside corners with reinforcing corners nested within each outside corner. The reinforcing corners are formed of reinforcing shoulders integrally joined to the end walls of the carton. Each reinforcing shoulder has three panel portions, two overlying a side wall and one overlying an end wall. Substantial portions of the panels of the reinforcing shoulder engage a floor of the carton to provide improved compressive strength.
