Blank for a packaging shell of a cup packaging, method for producing a blank, cup packaging having a packaging shell, and method for separating the cup packaging and the packaging shell

A blank for a packaging shell of a cup packaging, the cup packaging having a base, a rim opposite the base and a wall between the base and the rim, the blank being suitable for encasing the wall in order to form the packaging shell, the blank comprising:

• a planar carrier material having a first periphery and diametrically opposite a second periphery, as well as an upper periphery and diametrically opposite a lower periphery, wherein the peripheries at least substantially delimit the carrier material (4);
• the planar carrier material having a front side and a back side;
• a first connection portion assigned to the first periphery and disposed between the upper periphery and the lower periphery;
• a second connection portion assigned to the second periphery and disposed between the upper periphery and the lower periphery, provided for connecting to the first connection portion;
• a separation section disposed between the connection portions and at least partially extending from the lower periphery to the upper periphery;
• the separation section comprises:
• a central separation portion,
• an upper separation portion arranged above the central separation portion and between the central separation portion and the upper periphery, and
• a lower separation portion arranged below the central separation portion and between the central separation portion and the lower periphery;
• wherein each of the upper separation portion and the lower separation portion has, on the front side of the planar carrier material, at least one front incision in the carrier material at least partially extending from the lower periphery to the upper periphery;
• wherein each of the upper separation portion and the lower separation portion has, on the back side of the planar carrier material, at least one back incision in the carrier material at least partially extending from the lower periphery to the upper periphery;
• and
• wherein the central separation portion has at least one opening.
