Abstract: A collapsible container for milk cartons has a plate-like base member with first and second spaced parallel edges and third and fourth spaced parallel edges perpendicular to the first and second edges. First and second upper ledges extends upward perpendicularly from the base member along the first and second edges thereof. Third and fourth upper ledges extend upward perpendicularly from the base member along the third and fourth edges thereof. The third and fourth upper ledges are perpendicular to the first and second upper ledges. A first side panel is pivotally mounted in the third and fourth upper ledges next-adjacent the first upper ledge in a manner whereby the first upper ledge prevents the first side panel from falling outward. A second side panel is pivotally mounted in the third and fourth upper ledges next-adjacent the second upper ledge in a manner whereby the second upper ledge prevents the second side panel from falling outward.
