The blank (10) includes a first row (A) with four panels (32, 34, 36 and 38) that end up in the box as reinforcing sidewall and end wall panels, a middle row (B) contiguous with the first row (A) and having four panels (20, 24, 28 and 40) that end up in the box as sidewall and end wall panels.</p> |
