Abstract

A blank of sheet material for forming a polygonal container includes a bottom panel, two opposing side panels each extending from a side edge of the bottom panel, and two opposing end panels each extending from an end edge of the bottom panel. The blank also includes a foldover panel that is configured to lock the container in at least a partially formed position. The blank further includes a reinforcing panel assembly that includes an outer reinforcing corner panel extending from the first side panel, an outer reinforcing end panel extending from the outer reinforcing corner panel, an inner reinforcing end panel extending from the outer reinforcing end panel, and an inner reinforcing corner panel extending from the inner reinforcing end panel.

Dependent claims

A blank of sheet material for forming a polygonal container, said blank comprising:

a bottom panel, the bottom panel having at least one side edge, and at least one end edge;
two opposing side panels, each side panel extending from a side edge of the bottom panel;
two opposing end panels, each end panel extending from an end edge of the bottom panel;
a first foldover panel extending from a top edge of a first end panel of the two end panels, the first foldover panel configured to lock the container in at least a partially formed position;
a reinforcing panel assembly extending from a first side edge of a first side panel of the two side panels, the reinforcing panel assembly including:
an outer reinforcing corner panel extending from the first side edge of the first side panel;
an outer reinforcing end panel extending from a side edge of the outer reinforcing corner panel;
an inner reinforcing end panel extending from a side edge of the outer reinforcing end panel;
and
an inner reinforcing corner panel extending from a side edge of the inner reinforcing end panel,
wherein the first side panel is configured to form a first side wall of the container, and each of the first and the second reinforcing end panels is configured to form a first end wall of the container;
wherein the outer reinforcing corner panel and the inner reinforcing corner panel are configured to be disposed in juxtaposed face-to-face relation to one another to form a corner wall of the container,
wherein the inner reinforcing corner panel defines a terminal edge of the reinforcing panel assembly;
wherein the outer reinforcing end panel comprises a first cutout defined along a top edge thereof;
and the inner reinforcing end panel comprises a second cutout defined along a top edge thereof;
wherein the first cutout aligns with the second cutout to form a locking slot when the inner reinforcing end panel is folded inwardly in a face-to-face relationship with the outer reinforcing end panel.

A polygonal container comprising:

a bottom wall, the bottom wall having at least one side edge, and at least one end edge;
two opposing side walls, each side wall emanating from a side edge of the bottom wall;
two opposing end walls, each end wall comprising an end panel and a foldover panel, each end wall emanating from an end edge of the bottom wall, each foldover panel opposite the end edge and configured to lock the container in at least a partially formed position;
and a first reinforcing panel assembly extending between a first end wall of the two end walls and a first side wall of the two side walls, the first reinforcing panel assembly including:
an outer reinforcing corner panel emanating from a side edge of the first side wall;
a first reinforcing end panel emanating from a side edge of the outer reinforcing corner panel;
a second reinforcing end panel emanating from a side edge of the first reinforcing end panel;
and an inner reinforcing corner panel emanating from a side edge of the second reinforcing end panel, wherein the outer reinforcing corner panel and the inner reinforcing corner panel are disposed in juxtaposed face-to-face relation to one another to form a corner wall extending from an end edge of the first side wall to an end edge of the first end wall, wherein the inner reinforcing corner panel defines a terminal edge of the reinforcing panel assembly;
wherein the first reinforcing end panel comprises a first cutout defined along a top edge thereof;
and the second reinforcing end panel comprises a second cutout defined along a top edge thereof;
wherein the first cutout aligns with the second cutout to form a locking slot when the first reinforcing end panel is folded inwardly in a face-to-face relationship with the second reinforcing end panel.
