PROBLEM TO BE SOLVED: To provide an extraction bag (a material to be extracted is stored or not) with a support tool, which is stably placed on an extraction vessel so as to safely perform an extracting action, and to provide a sheet composite sheet with which the bag is produced with high efficiency by a simple process. SOLUTION: This extraction bag with the support tool consists of a bag body which is produced through the use of a bag producing machine (and a filling machine as necessary) by using a sheet composite body where support members are arranged and joined along the center line of a water permeable filter sheet member and folding it in two and where the material to be extracted is stored or can be stored and also consists of the support member having four legs. The upper end edge of the bag is opened, the center part folding piece of the support member is outward bent to widely open the opening part, the opened state is fixed and the four leg parts are extended to the outside. The bag in this state is placed on the extraction vessel, an extraction liquid (hot water) is poured into the material to be extracted, and then, extraction is safely performed. |
