Abstract
A drip bag with hook members adhered to the outer surfaces of two opposing-face sheets of a bag body is configured to increase the area of an opening of the bag body and stabilize the shape of the opening. A drip bag has a body formed of a water-permeable filtering sheet, an upper end to be opened, and hook members formed of a thin plate-shaped material and provided on outer surfaces of two opposing-face sheets of the bag body. The hook member includes: an upper-stuck part adhered to the bag body along the opening; a center part below the upper-stuck part at the center in the width direction thereof and formed so as not to be pulled out from the bag body; and a hook part not adhered to the bag body. First oblique folding lines and second oblique holding lines are formed on the upper-stuck part by respective angles.
