<P>PROBLEM TO BE SOLVED: To improve useability and drip properties of a drip coffee extraction bag to be set on a cup by the bag only being placed on the cup to be set and to solve restrictions such as a smaller area of a support body despite an advantage of low costs in a bag method comprising previously sticking the support body onto a filter, closing three sides of the filter and stuffing the inside with coffee powder. <P>SOLUTION: The support body is integrally placed in the front side and the back side of the filter bag. Opening the top of the bag develops the support body three-dimensionally at the same time. Thereby the bag can be set by only being placed on the cup, enhancing the drip properties as well. <P>COPYRIGHT: (C)2008,JPO&INPIT |
