Abstract: A support-equipped extracting bag for a drink, for example coffee, comprises an extracting bag member 2 containing therein a drink material to be extracted and having a front face section 2a and back face section 2b each comprising a filtering sheet; and a support member 3 attached to the bag member and covering an upper half portion of the bag member, to hygienically keep a top end of the bag member to be opened during storage and to enable the bag member to be stably and safely held in a cup, wherein the upper middle portion of the support member and the upper portion of the bag member can be opened by removing the upper middle portion of the support member and the upper portion of the bag member along cut lines 8 and 9 or vacant area 10 or 11 and a row of perforations 13 formed through the support and bag members, and by bending the right and left side upper portions of the support member inward along folds or dotted cuts 14 and 15 formed in the right and left side upper portions of the support member.

Abstract: An antibacterial, biodegradable extracting container has a filtering surface formed from a water-permeable woven or knitted fabric formed from fibers comprising, as a principal component, an antibacterial, biodegradable polylactate polymer, and having a thickness of 1 to 100 dtex, wherein, preferably, the filtering surface is formed from the woven fabric having a cover factor K of 1600 to 6400, determined in accordance the following equation: K=(N×(A)1/2/T)+(M×(B)1/2/S) wherein, N=warp density (yarns/10 cm), M=weft density (yarns/10 cm), A=thickness (dtex) of the warp yarns, B=thickness (dtex) of the weft yarns, T=specific gravity of the warp yarns and S=specific gravity of the weft yarns.
