Beschreibung
Zusammenfassung:	A corrugated paperboard box is provided in which when flaps are bent, a perforated line along which the flaps can be separated from the box is less likely to break. Such a corrugated paperboard box includes a peripheral wall (41) and top flaps (11, 12, 13 and 14), and is formed, at the boundary area between the peripheral wall (41) and the top flaps (11, 12, 13 and 14), with a groove-shaped reverse scoreline (16) recessed on the side of an outer linerboard (1), and a pair of groove-shaped recesses (19a and 19b) recessed on the side of an inner linerboard (2), and extending in parallel to each other so as to sandwich the area in which the reverse scoreline (16) extends. The corrugated paperboard box is further formed, in one (19b) of the groove-shaped recesses, with a perforated line (17) along which the top flaps (11, 12, 13 and 14) can be separated from the peripheral wall (41). The top flaps (11, 12, 13 and 14) can be bent along the perforated line (17) toward the inner surface of the peripheral wall (41).
