The present invention relates to a one-piece blank (14) made of corrugated cardboard for the production of a display case (1), the case, the method and the machine for producing said case. The blank comprises a band (2) of panels (15, 16, 17, 18) connected together in pairs by parallel fold lines (24, 25, 26, 27). The band (2) comprises a precut transverse line (20) making it possible to divide the blank into two half-blanks (21, 22), said transverse line determining on either side and for each parallel fold line (24, 25, 26, 27) two separate portions of fold line (24′, 24″; 25′, 25″; 26′, 26″; 27′, 27″) offset relative to one another in order to make it possible to at least partly compensate for the thicknesses of cardboard when the second half-blank is wrapped over the first half-blank around a mandrel.

1. 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. 2. The blank as claimed in claim 1, wherein the at least four main rectangular panels includes: a first central panel;a second panel;a third panel; anda fourth panel,wherein the first central panel is connected on its lateral sides to the second panel and to the third panel respectively by said first fold lines, the portions of said first fold lines of the first half-blank being offset toward an inside of said first central panel relative to the portions of the same first fold lines of the second half-blank,wherein the second panel and third panel are themselves connected toward the outside to the fourth panel or to a bonding tab, by said second fold lines, the portions of said second fold lines of the first half-blank being offset toward an inside of said second panel and said third panel relative to the portions of the same second fold lines of the second half-blank. 3. The blank as claimed in claim 2, wherein the offset between portions of said first fold lines of the first half-blank and the portions of the same first fold lines of the second half-blank is of one thickness or substantially of one thickness of the corrugated cardboard and the offsets between portions of said second fold lines of the first half-blank and the portions of the same second fold lines of the second half-blank is of two thicknesses or substantially of two thicknesses of the corrugated cardboard. 4. The blank as claimed in claim 1, wherein the at least four main rectangular panels includes: a first central panel;a second panel;a third panel; anda fourth panel,wherein the first central panel is connected on each of its lateral sides respectively to the second panel and to the third panel by two of said parallel fold lines, said second panel and said third panel each including a substantially central opening adjacent to the transverse precut line,wherein, after formation of the case by separation of the blank into the first half-blank and second half-blank and by folding and gluing said first half-blank and said second half-blank to each other, a display tray and an upper portion of the case are produced and the substantially central openings of the second and third panels are configured to allow for separation of case by pulling display tray relative to the upper portion of the case. 5. The blank as claimed in claim 1, wherein the transverse precut line defines an adjacent trapezoidal area on the blank which is configured to, at least in part, form a display case with side walls having an at least partially inclined peripheral side. 6. The blank as claimed in claim 1 wherein the at least four main rectangular panels includes: a first central panel;a second panel; anda third panel,wherein the first central panel is connected on its lateral sides respectively to the second and to the third panel by two of said fold lines,wherein the transverse precut line includes an upward sloping portion and a downward sloping portion that are respectively located on the second panel and the third panel. 7. The blank as claimed in claim 1, wherein the at least four main rectangular panels includes: a first central panel;a second panel;a third panel; anda fourth panel,wherein the transverse precut line extends through each of the first central panel, the second panel, the third panel, and the fourth panel. 8. A packing case formed from material made of corrugated cardboard sheet, comprising: two elements configured to be separated manually from one another, including: a first element forming a display tray; anda second element forming an upper portion of the case,wherein the first and second elements are obtained from a single blank comprising: a band including: at least four main rectangular panels connected together in pairs by parallel 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 first element and a top of the second element;wherein the band includes a precut transverse line configured to divide the blank into a first half-blank and a second half blank, which are configured to form said two elements,wherein said precut transverse line defines 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, and wherein the precut transverse line defines an adjacent trapezoidal area on the blank which is configured to, at least in part, form a display case with sidewalls having an at least partially inclined peripheral side, andwherein the two elements are configured to be inserted in one another and secured to one another by adhesive. 9. The case as claimed in claim 8, wherein the at least four main rectangular panels includes: a first central panel;a second panel;a third panel; anda fourth panel,wherein the first central panel is connected on each of its lateral sides, respectively to the second panel and to the third panel by two of said parallel fold lines,wherein said second and third panels each include a substantially central opening adjacent the transverse precut line,wherein the substantially central openings of the second and third panels are configured to allow the separation by pressure of one of said two elements relative to the other element of said two elements after bonding of the one element to the other element.
