PURPOSE:To obtain an inexpensive paper cartridge container usable for an air hand gun by combining a paper cylindrical member, a metallic plunger to be fitted therein and an aluminum back seamer which is a cap member and providing these members with respectively specific structures. CONSTITUTION:The main parts of the paper cartridge container are composed of the paper cylindrical member 1, the metallic plunger 2 and the aluminum back seamer 3. The paper cylindrical member 1 is obtd. by forming a mouth part 4 for nozzle mounting on the front end side of a cylindrical body 11 formed by laminating three later laminated sheets 5 consisting of a high-density polyethylene film 5a, aluminum foil 5b and kraft paper 5c, >=4 layers of kraft paper 6 to 9 and two layer laminated sheets 10 consisting of wood free paper 10a and aluminum foil 10b. The metallic plunger 2 is obtd. by forming a blind cylindrical shape to be fitted into the paper cylindrical member l and cutting the open end edge thereof to a straight shape. Further, the aluminum back seamer 3 is obtd. by forming the seamer of a cap member having an unsealing part 15 and hermetically closing the paper cylindrical member 1. |
