Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
83 words
A closed, foldable blank for forming two and three dimensional structures, comprising at least three large square faces, each face being connected to two adjacent faces by transverse fold lines, and each face having a third transverse fold line bisecting said face, a further fold line perpendicular to said transverse fold lines at the midpoints thereof, thereby dividing each face into four small squares, and two diagonal fold lines connecting the corners of each face thereby dividing each small square into two triangles.
