摘要： A drip bag includes a bag main body formed of a water permeable filter sheet and hooking members made of a thin plate-like material on two opposite outer surfaces. Each hooking member includes upper bonded, central, and a pair of arm portions from the central to toward the upper bonded portion, and a pair of hooking portions. The arm portions are mutually spaced with a bag main body width center line between them. Each hooking portion extends downward in and are not bonded onto the bag main body. Each arm portion can be pulled up from the bag main body at an upper part, and has a fixed side on the bag main body at a lower part. The fixed side is inclined relative to a bag main body width direction. A bag main body opening portion opens wider even when a cup opening diameter is small.

摘要： A drip bag has a body formed of a water permeable sheet, an openable upper end, and hook members formed of a plate-shaped material on outer faces of two opposing body surfaces. The hook member includes: an upper stuck part adhered to the body along its opening in an elongated shape; a center part located below the upper stuck part at the body center in its width direction not to be pulled out; and a hook part not adhered to the body. Two oblique folding lines are formed on the upper stuck part with a center line therebetween, and being more spaced from the center line while extending from a lower to an upper portion of the upper stuck part, the center line bisecting the body in its width direction. A vertical folding line is formed downwardly from immediately below a lower end of the oblique folding lines.

摘要： A dip-type extraction bag having a bag main body in a planar shape, being formed of a water-permeable filter sheet and filled with an extraction material, wherein the extraction efficiency is improved by providing the body with a specific gripping portion formed from a thin plate-like material and regulating the characteristics of the sheet. The extraction bag includes a bag main body, a thin plate-like member provided on an outer surface thereof, and an extraction material sealed in the bag main body, which is subjected to extraction. The bag main body is a flat bag that has two facing surfaces. The thin plate-like member has a gripping portion that protrudes or is able to protrude from an upper side or the outer surface of the bag main body. The bending resistance (41.5° cantilever method in JIS L 1913:2010 (ISO method)) of the water-permeable filter sheet is 0.09 to 6.0 mN·cm.

摘要： An extraction bag 1A includes a bag main body 3 formed of a water permeable filter sheet 2, a thin plate-like member 10 provided on an outer surface of the bag main body 3, and an extraction material filled in the bag main body 3. The bag main body 3 has a first surface 3A and a second surface 3B opposed to each other, and an upper side 4a corresponding to edges thereof. The thin plate-like member 10 includes a first member 10A on the first surface 3A of the bag main body, and a second member 10B on the second surface 3B of the bag main body, and these 10A and 10B are continuous with each other via a first horizontal folding line Lh1 extending along the upper side 4a. The thin plate-like member 10 includes a pair of elongated regions 12 (opposed to each other) sandwiching a central bonded portion 11 of the first member 10A from its left and right sides that are provided astride the first member 10A and the second member 10B and are pulled out from the bag main body, and a vertical folding line Lv1 along which the elongated regions 12 can be pulled out. This extraction bag 1 is a tea bag type extraction bag filled with an extraction material such as ground coffee and capable of allowing the bag main body to be easily sunk into the hot water or moved up and down.
