To provide a method for manufacturing a tea bag designed into a complicated shape.A nonwoven fabric having a predetermined shape is folded back into a bag shape and a part of an end portion of a folded back nonwoven fabric is pressed and bonded to form a bag body 22 having an opening portion 23. From the opening portion 23, In a method 1 for manufacturing a tea bag in which tea leaves are stored and the opening is sealed, a nonwoven fabric having a predetermined shape is formed as an incision type cloth 1 having a planar shape obtained by cutting out an outer shape of a predetermined object, and the incision type cloth 1 (6, 7) are integrally provided on the outer peripheral end portion (2a, 3a) of the incision type cloth 1, and a cut portion (12a, 12b) obtained by cutting a part of the incision type cloth 1 is provided, The protrusions (12a, 12b) are folded back inside the formed bag body 22, and the distal ends of the protruding portions (6, 7) are inserted from the inside of the bag body 22 into the cut portions (12a, 12b) It protruded to the outside.(FIG.【課題】複雑な形状にデザイン化されたティーバッグの製造方法の提供。【解決手段】所定形状の不織布を袋体状に折返し、折り返した不織布の端部の一部を圧着して貼り合わせて開口部23を有する袋体22を形成し、開口部23から袋体に茶葉を収納して開口部を封止するティーバッグの製造方法1’において、所定形状の不織布を所定の物体の外形形状を切り開いた平面形状を有する切開形布1として形成し、切開形布1の外周端部(2a,3a)に突起部(6,7)を一体に設け、切開形布1の一部を切り裂いた切裂部(12a,12b)を設け、切開形布1を折り返して形成した袋体22の内側に突起部(12a,12b)を折り返し、突起部(6、7)の先端を袋体22の内側から切裂部(12a,12b)に挿通させて袋体22の外側に突出させた。【選択図】図2
