PROBLEM TO BE SOLVED: To provide paper boxes of various shapes comprising the combination of curves and apexes. SOLUTION: A mold is formed, where a clearance between an outer mold and an inner mold is equal to or slightly larger than the thickness of paper used as the side face of a box, and smaller than the band width of the side face. Then, the band for the side face is fitted into a gap between the outer mold and the inner mold. A Menko (hood) is placed on the inner mold. When the hood is inserted, the inner mold 5 is dropped. The dropped inner mold is taken out to be placed on the Menko in a mold. An inner mold 6 is pushed in to the bottom to position a band 7 and the Menko 9. The Menko set in a fixed position, the recess of the band, a corner, and a part to which external force is applied are fixed by quick-drying glue such as an instant adhesive. Then, normal fixing is carried out by a glue such as an emulsion. Thus, productivity is improved and strength is secured. COPYRIGHT: (C)2011,JPO&INPIT
