Abstract
A sheet structure, fabricated from paper and/or paperboard material, provides a thickness dimension ordinarily associated with corrugated paperboard material. The sheet structure is constructed from a first planar linerboard sheet and a second non-planar linerboard sheet, wherein a plurality of projections are cut and folded from the second linerboard sheet and are adhesively coupled to the first linerboard sheet, such that portions of the projections define a standoff between the first and second linerboard sheets.
Claims8
A paperboard panel, comprising:
- a first linerboard;
- a second linerboard;
- and
- at least one spacer structure extending between the first linerboard and the second, the at least one spacer structure further comprising at least one flap member extending monolithically from one of the first and second linerboards, a tip of the at least one flap member being coupled to an inwardly-facing surface of the other of the first and second linerboards.

A method of fabricating a paperboard panel, comprising the steps of:
- fabricating a first linerboard;
- fabricating a second linerboard;
- forming a spacer structure, the spacer structure comprising at least one flap member extending monolithically from one of the first and second linerboards, the step of forming a spacer structure comprising the steps of
- cutting at least one flap member into one of the first and second linerboards,
- folding the at least one flap member in a first direction, into an orientation defining an angle with respect to the one of the first and second linerboards,
- folding a tip portion of the at least one flap member in a second direction, to define a body portion of the at least one flap member, extending between the tip portion and the one of the first and second linerboards, the tip portion being folded into an orientation defining an angle with respect to the body portion;
- coupling a surface of the tip portion of the at least one flap member to an inwardly-facing surface of the second linerboard.
