1. A one-piece blank for a cuboid folding box, the one-piece blank comprising:
five main panel segments arranged in a row and separated from one another on transverse sides via main fold lines; wherein
a first main panel segment defines a first end of the blank;
a second main panel segment adjoins the first main panel segment;
a third main panel segment adjoins the second main panel segment;
a fourth main panel segment adjoins the third main panel segment;
a fifth main panel segment adjoins the fourth main panel segment;
the fifth main panel segment defines a second end of the blank;
the five main panel segments are foldable about the main fold lines;
a second secondary panel segment, including an edge, adjoins the second main panel segment on a longitudinal side;
a third secondary panel segment adjoins the third main panel segment on a longitudinal side via a third secondary fold line;
secondary fold lines are perpendicular or substantially perpendicular to the main fold lines;
the secondary fold lines are arranged perpendicularly or substantially perpendicular to the main fold lines;
a first perforation line extends over the third main panel segment and at least partially over the third secondary panel segment;
the third secondary panel segment is divided by the first perforation line into a first region adjacent to the second secondary panel segment and a second region adjacent to a fourth secondary panel segment;
a shape of the second secondary panel segment and a course of the first perforation line are configured such that, in a folded state, the second secondary panel segment overhangs the first perforation line in a region of the third secondary panel segment;
a second secondary fold line and a second main fold line separating the second main panel segment from the third main panel segment define an intersection point;
x is a distance of a first point on the second secondary fold line to the intersection point and a distance of a second point on a straight-line extension of the second main fold line to the intersection point;
h is a perpendicular distance from the second secondary fold line to an edge of the second secondary panel segment at the first point;
b is a perpendicular distance from a straight-line extension of the second main fold line to the first perforation line at the second point; and
a following relationship is satisfied: for each x that defines first and second points that define b and b, b≤0.98h.
