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.

Abstract: A one-piece corrugated fiberboard blank and the triple-end container assembled therefrom wherein the blank includes a rectangular bottom panel with a side panel hingedly attached to each of the two opposite sides thereof. Hingedly attached to the remaining two opposite sides of the bottom panel are first, exterior end panels, each having a hand-hold slot formed therein. Second, intermediate end panels sized in width to extend approximately half way across the first end panel in the assembled container are hingedly attached to the opposite ends of each side panel. Each intermediate end panel has a cutout complementary to the hand-hold slot in the first end panel and includes an extension hingedly attached thereto that folds back upon the intermediate end panel to form the third, innermost end panel.
