Zusammenfassung: | A corrugated paperboard box is provided into which products can be packed easily, and in which flaps can be accurately brought into abutment with each other. The corrugated paperboard box includes a peripheral wall (31), a top flap (11), and a groove-shaped normal scoreline (15) formed between the peripheral wall (31) and the top flap (11), and recessed on the side of an inner linerboard (2) such that the top flap (11) can be bent along the normal scoreline (15) toward the inner surface of the peripheral wall (31). The corrugated paperboard box further includes a groove-shaped reverse scoreline (16) formed at the position spaced apart from the normal scoreline toward the top flap (11) to extend in parallel to the normal scoreline (15), and recessed on the side of an outer linerboard (1) such that the top flap (11) can be bent along the reverse scoreline toward the outer surface of the peripheral wall (31), and a shallow scoreline (24) extending in parallel to the reverse scoreline (16) on the opposite side of the reverse scoreline (16) from the normal scoreline (15), and recessed on the side of the inner linerboard (2).
