PURPOSE: To simply extract coffee by making the support members provided on both sides of a filter bag rotatable from the initial positions where they are mounted on the filter bag in the flat state to the support positions where they are faced to the lateral direction. CONSTITUTION: Support members 14, 15 are rotatably or foldably connected at the accurately matched positions on both sides of the outer face of a filter bag 13. The support members 14, 15 are mounted in the folded state on both sides of the filter bag 13 folded in the flat state at the initial positions. The folding line 20 of the support members 14, 15 is connected to the filter bag 13, and it is extended at the position apart from the upper edge section 19 of the filter bag 13 by the prescribed distance. The support members 14, 15 can be deployed or rotated to supporting positions where they are faced to the lateral direction from the folded positions where they are mounted on the filter bag 13 in the flat state centering on the folding line 20 in the lateral direction or horizontal direction. |
