PROBLEM TO BE SOLVED: To provide a luxury beverage extraction bag provided with a supporter capable of easily spreading a cup mounted type supporting member, opening an extraction bag member upper end, safely mounting it on a cup and successively executing drip extraction and immersion extraction. SOLUTION: Only one side edge end of a supporting member 3 provided with a front surface part 4a and a back surface part 4b is continued, the upper part of an extraction bag member 2 is inserted and adhered to the inner side of the supporting member 3, and at the upper end part of both front and back surface parts 4a and 4b of the supporting member 3, a fold, a perforation or a cut for making it foldable to the inner side is formed. Then, by making the width of a side face part farther from the continuous side edge end 5a of the supporting member 3 between the right and left side face parts 2a and 2b of the extraction bag member 2 wider than the width of the closer one and folding the upper end part of the continuous side edge part 6a and 6b of the supporting member 3 to the inner side, both front and back surface parts 4a and 4b of the supporting member 3 are spread in a hinge shape with the continuous side edge end 5a as a shaft. |
