PROBLEM TO BE SOLVED: To equalize a filtering area and a thickness of a filtering layer so as to improve the extraction property by constituting a bag for extracting coffee and tea by a rectangular bag main body made of filtering sheet and handle hold parts attached at symmetrical positions on both front and rear surfaces. SOLUTION: A bag for extraction 1 consists of a rectangular bag main body 2 made of a flexible sheet having the filtering property and handle hold parts 3, 3' which are made of stiff sheet and are attached at symmetrical positions on both front and rear surface. Handles 4, 4' produced inside the handle hold parts 3, 3' by blanking them are connected with the handle hold parts through a remaining part, and the blanked parts are pulled up to form the handles 4, 4'. Cut-in parts 5, 5' opened downward are formed in the handles 4, 4'. Moreover, small handles 6, 6' are formed by extending on the same plane, and cut-in parts 7, 7' opened downward are formed at tips thereof. When the handles 4, 4' are pinched and the cut-in parts there of are applied to a fringe of a cup, the small handles 6, 6' are held on an extension line of the handle hold parts. |
