To provide market with paper container disassembly tools which make it possible to simplify labor for arrangement after cutting by simply cutting paper containers such as paper packs and corrugated cardboard boxes straight, to prevent accidents causing incised wound associated with disassembly operation, and to achieve resource saving by eliminating need for discarding the disassembly tools.
A butting member structure is provided on the paper container disassembly tool so as to guide an edge by using two inner faces forming a cutting ridge line as a guiding face. The edge is automatically guided to the ridge line by stress generated by cutting operation. A wall face shape of the paper container forming a ridge line to be cut is maintained so as to improve efficiency of the cutting operation and to prevent an operator from suffering an accident causing the incised wound by the edge. The edge can be cut out so as to restore sharpness when a cutter is deteriorated.
