Abstract
A corrugated alternate displacement cushion may be formed from a corrugated cardboard sheet having cutout rows of cutout sections that are spaced in the transverse direction across the corrugated cardboard sheet and separated by corresponding lands. The cutout sections of adjacent cutout rows do not overlap in the transverse direction. When the corrugated cardboard sheet is folded up around transverse creases, inner and outer sides of the cutout sections may be covered by lands of other cutout rows such that air pockets defined by the cutout sections are formed within the corrugated alternate displacement cushion.

A corrugated alternate displacement cushion comprising:
- a corrugated cardboard sheet having a longitudinal direction and a transverse direction that is perpendicular to the longitudinal direction;
- a first cutout row having first cutout sections in the corrugated cardboard sheet that are spaced in the transverse direction across the corrugated cardboard sheet and separated by first lands;
- and
- a second cutout row having second cutout sections in the corrugated cardboard sheet that are spaced in the transverse direction across the corrugated cardboard sheet and separated by second lands, wherein the first cutout sections do not overlap the second cutout sections in the transverse direction,
- wherein, when the corrugated cardboard sheet is folded up to form the corrugated alternate displacement cushion with a rectangular cross-section, the first lands overlay the second cutout sections and the second lands overlay the first cutout sections with the first lands and the second lands overlapping and engaging such that air pockets defined by the first cutout sections and the second cutout sections are formed within the corrugated alternate displacement cushion.
A corrugated alternate displacement cushion fabricated from a corrugated cardboard sheet having a longitudinal direction and a transverse direction that is perpendicular to the longitudinal direction, the corrugated alternate displacement cushion comprising:
- horizontal plies of the corrugated cardboard sheet that are stacked vertically;
- vertical plies of the corrugated cardboard sheet, wherein each of the vertical plies connects a pair of the horizontal plies to each other;
- and
- first cutout sections defined in a first horizontal ply of the horizontal plies, wherein the first cutout sections are spaced in the transverse direction across the first horizontal ply and are separated by first lands of the first horizontal ply, wherein the first cutout sections are enclosed by a second horizontal ply of the horizontal plies that is vertically above the first horizontal ply and a third horizontal ply of the horizontal plies that is vertically below the first horizontal ply to define first air pockets within the corrugated alternate displacement cushion.
A corrugated cardboard sheet comprising:
- creases extending in a transverse direction of the corrugated cardboard sheet that is perpendicular to a longitudinal direction of the corrugated cardboard sheet, wherein the creases define horizontal plies in the corrugated cardboard sheet and vertical plies in the corrugated cardboard sheet, wherein each of the vertical plies is disposed between a pair of horizontal plies, and wherein the horizontal plies are stacked vertically when the corrugated cardboard sheet is folded up around the creases;
- first cutout sections and first lands extending in the longitudinal direction from a first horizontal ply of the horizontal plies across a first vertical ply of the vertical plies and at least partially across a second horizontal ply of the horizontal plies, wherein the first cutout sections are spaced in the transverse direction and separated by the first lands;
- second cutout sections and second lands extending in the longitudinal direction from a third horizontal ply of the horizontal plies across a third vertical ply of the vertical plies and at least partially across a fourth horizontal ply of the horizontal plies, wherein the second cutout sections are spaced in the transverse direction and separated by the second lands, wherein the first cutout sections and the second cutout sections do not overlap in the transverse direction, and wherein the first cutout sections and the second cutout sections have a cutout width and the first lands and the second lands have a land width that is greater than the cutout width, and
- wherein, when the corrugated cardboard sheet is folded up around the creases, the first horizontal ply and the second lands enclose the first cutout sections to form first air pockets, and the first horizontal ply and the first lands cover an interior of the second cutout sections.
