Claims

[Claims for Utility Model Registration] A vertical score line is cut only in the outer layer paper at one corner from the upper edge of a pleated multilayer cylindrical body made of multiple layers, and from the end to one side edge. Cut out the 45° fold line, fold the paper layer at the corner inside the cylindrical body to form an inlet, and then cut the top of one of the folds forming the fold at the corner other than the next inlet. A vertical score line is cut only on the outer layer, and a crease line is cut at the end thereof parallel to the upper and lower edges, and the outer layer piece and other layers are separated via the vertical score line, leaving only the outer layer piece. All of the other layers are folded back in one direction along the crease line to form a bent portion, and adhesive is applied to the inner surface of this outer layer piece and the outer surface of the bent portion. The pleated multilayer bag further has an inlet formed by wrapping the folded part and attaching outer layer pieces to the walls of the folded cylindrical body so as to cover the folded part.
