PROBLEM TO BE SOLVED: To provide a material sheet capable of manufacturing, easily and reasonably, a favorite beverage extracting bag containing a covered water permeable sheet.SOLUTION: In a material sheet for manufacturing a favorite beverage extracting bag, on a long filtering sheet 2 to which a weakening line 6 is provided along length direction, a hooking device 1 is pasted to one surface of the filtering sheet 2, on the right and left of the weakening line 6 to face each other. On the other surface of the filtering sheet 2, a covered water permeable sheet 3 whose width is narrower than that of the filtering sheet 2 is pasted. This pasting is made at pasting portions 3a and 3b in length direction at right and left ends of the covered water permeable sheet 2. The weakening line 6 of the material sheet may be cut or may not be cut. In a case it is not cut, cutting is made before or during manufacturing of the extracting bag. By using the material sheet, with the weakening line 6 as a folding line, folding is made in two in such a manner as the hooking device 1 may be on the outside, and then, a known means is applied to provide the extracting bag. |
