ABSTRACT:
A collapsible, self-erecting, tray-type, one-piece carton having liquid-tight lower corners. The end walls of the carton each have a length greater than the width of the bottom wall and each have a pair of side edges that project a slight distance beyond the side walls, so that no opening exists at any lower corner of the carton where related side walls and end walls are joined to each other and to the bottom wall panel.
