COLLAPSIBLE CONTAINER WITH IMPROVED CORNERS

摘要

A collapsible container having thick corrugated walls with double crease corners. The double crease corners define two 45° angles instead of one 90° to allow the container to maintain a generally rectangular shape and reduce the tendency of the side panels to bias outward when the container is filled with a flowable material.

主权项

1. A collapsible container comprising:
(a) a first side panel, wherein the first panel is at least triple corrugated; (b) a second side panel, wherein the second panel is at least triple corrugated; (c) a third side panel, wherein the third panel is at least triple corrugated; (d) a fourth side panel, wherein the fourth panel is at least triple corrugated; (e) a first crease provided in the first side panel, wherein the first crease compresses the first side panel to a thickness of less than eighty percent of the greatest thickness of the first side panel; (f) a second crease provided in the second side panel, wherein the second crease compresses the second side panel to a thickness of less than eighty percent of the maximum thickness of the second side panel; and (g) wherein the center of the first crease is located a predetermined distance from the center of the second crease, wherein the predetermined distance is greater than the minimum thickness of the first side panel and less than four times the maximum thickness of the first side panel.
