ABSTRACT:
A blank of foldable sheet material for assembling a hollow figure having inwardly directed conical depressions comprises a sheet of foldable material having the shape of a square or rectangle, without interior cuts or exterior tabs scored or marked for scoring in four areas along circular lines tangential to each other and having a radius of one fourth the diagonal of the sheet if a square and one half the narrower side if a rectangle. The blanks have each of the circularly scored areas formed by rolling into a conical shape comprising from about four-ninths to two-thirds of a cone. Six of the blanks assemble into a self-supporting interlocking hollow figure having eight inward-facing cones. If desired, the visible surfaces of the hollow object may have a decorative or informative imprint or coating thereon.
