PROBLEM TO BE SOLVED: To insert a set cutter into a cartridge pack body filled with a joint filler and thereby easily cut an aluminum film by providing a strong collar piece on the outer peripheral sliding face of a small cylindrical part and also an arclike strong pillar inside the strong collar piece and at the same time, fitting a sharp breaking blade on the upper end of the arclike strong pillar and further, fitting a thin wall rotary cutting blade to the both ends of a descent slope on the upper end. SOLUTION: A plurality of pillars 12 for supporting the outer peripheral collar piece of an opening 10 of a receiving base end are provided in the attachable/detachable nozzle B for filling a joint filler and further, a supporting base plate 13 is provided on the inner peripheral sliding face. At the same time, a tip blind end cylindrical body is installed which has a receiving fixed pillar 15 formed in a small dia. 141 passageway 142 extending toward the tip blind end. A hitting breaker has a strong collar piece 11 formed on the outer peripheral sliding face of a small cylindrical part and also an arclike strong pillar 2 formed inside the strong collar piece 11 and further, has a sharp breaking blade 3 formed on the upper end. In addition, a thin wall rotary cutting blade 5 is formed at both ends of a descent slope on the upper end. The attachable/detachable nozzle B for filling a joint filler on which the set cutter is mounted, is installed on a cartridge pack C filled with the joint filler to break through an aluminum film 19 and thus the aluminum film 19 is certainly cut using the thin wall rotary cutting blade 5. |
