Blank and packaging for pack of pots with connection/deformation sections

A flat blank, intended for forming a packaging for a pack of pots, the pots being of the type having a bottom wall, a side wall closed on itself, and a top closure, the pack including at least one layer of base pots and, optionally, one or more layers of pots stacked vertically on top of the layer of base pots, the blank being of the tubular shell type of cardboard or the like, comprising:

• side by side in a longitudinal direction:
• a top panel, two side panels, a base panel, a closure panel, and a securing means for closing the erected blank on itself,
• transverse score lines, extending in a transverse direction substantially perpendicular to the longitudinal direction, suitable and intended for folding the panels, for erecting the blank, and for forming the packaging and the pack,
• four sets of corner post panels, each set of corner post panels extending from a transverse end of a side panel and able to be erected relative to said side panel so as to form an erected corner post,
• longitudinal score lines, suitable and intended for folding the panels of the sets of corner post panels, for erecting the sets of corner post panels, and for forming the erected corner posts,
• a receiving portion extending over a portion of the base panel, for receiving the bottom walls of the base pots,
• characterized in that:
• the receiving portion is formed by a longitudinally median transverse portion of the base panel, and is bounded transversely on the base panel by two intermediate base score lines,
• the intermediate base score lines define, with the longitudinal ends of the base panel, two connection/deformation sections extending over the base panel on each side of the longitudinally median receiving portion of the base panel,
• the intermediate base score lines form two deformable hinges, such that the longitudinally median receiving portion of the base panel can be moved relative to the longitudinal ends of the base panel along an axis perpendicular or substantially perpendicular to the receiving portion after erection of the blank and formation of the packaging and the pack.
