Claim:
A one-piece blank of corrugated cardboard for production of a display case comprising: a band including: at least four main rectangular panels connected together in pairs by parallel fold lines including first fold lines and second fold lines, and furnished with two series of flaps situated on each side of said band, wherein the flaps are configured to at least partially form a bottom of the case and a top of the case, respectively; wherein the band includes a precut transverse line configured to divide the blank into a first half-blank and a second half-blank, said precut transverse line defining on each of its lateral sides two separate portions of each of the parallel fold lines, wherein the two separate portions of each parallel fold line are offset relative to one another such that the offset at least partly compensates for one or more thicknesses of the corrugated cardboard when the second half-blank is wrapped over the first half-blank around a mandrel.
