发明名称 EXTRACTION BAG WITH SUPPORT, EXTRACTION BAG WITH SUPPORT CONTAINING A MATERIAL TO BE EXTRACTED, AND SHEET COMPOSITE FOR PRODUCING THE BAGS
摘要 An extraction bag with support comprises a support member and a bag member which contains a material to be extracted or which is capable of containing a material to be extracted, and is obtained by using a sheet composite on which the support member is arranged and joined along the center line of a water-permeable filtering sheet member, by folding the sheet composite into two and by passing it through a bag-making machine (and, as required, through a filling machine). The head portions of the extraction bag with support are torn apart, the right and left ends are pushed down or up toward the inside to push open the head portions. At the same time, the leg portions continuous with the head portions are folded down to place the extraction bag with support on an extraction container. An extracting solution (hot water) is poured into the material to be extracted that is filled through the portion cut and torn away from the head portions or onto the material to be extracted that has been contained therein, thereby to safely conduct the extraction.
