PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape easy-to-open corrugated box designed so that a pressure-sensitive adhesive tape stuck to seal the corrugated box can be extremely easily and securely peeled with a small force without damaging a nail. SOLUTION: A main cutting line 31 is formed near the pressure-sensitive adhesive tape 20 stuck to the corrugated box. Cutting lines 32 for pressing are formed opposite the pressure-sensitive adhesive tape 20 at both ends of the main cutting line 31. A site surrounded by the main cutting line 31 and the cutting lines 32 for pressing is defined as a pressable piece 33. Sub-cutting lines 34 are formed on the pressure-sensitive adhesive tape 20 side at both ends of the main cutting line 31. A cutting line 35 for removal is formed between the sub-cutting lines 34. A site surrounded by the main cutting line 31, two sub-cutting lines 34 and 34, and a cutting line 35 for removal is defined as a cut-off piece 36. A site surrounded by the cutting line 35 for removal and the sub-cutting lines 34 is defined as a strippable piece 37. COPYRIGHT: (C)2009,JPO&INPIT
