Abstract:
A drip bag having a simple structure, obtained by affixing a sealing member to the two outer surfaces of a bag body, wherein the surface area of the opening of the bag body is enlarged and the shape of the opening is stabilized. The drip bag (1A) is formed from a water-permeable filtration sheet (20), and comprises a bag body (2) with an upper edge that opens, and a sealing member (10) made from a thin plate-shaped material, and which is provided to the two outer facing surfaces of the bag body (2). The sealing member (10) comprises: an upper affixing part (12) which is affixed to the bag body (2) in a band shape along the opening (3) of the bag body (2); a central part (first central affixing part (13)) which is formed in the central part in the width direction of the bag body (2) underneath the upper affixing part (12) so as not to be able to be able to be lifted; and a sealing part (11) which is not affixed to the bag body (2). In the upper affixing part (12), a pair of diagonal fold lines (L1a, L1b) are formed so as to extend in a direction away from a center line which divides the bag body (2) in two from the lower edge to the upper edge thereof, and so as to have the center line interposed therebetween. A vertical fold line (L2) is formed in a downward direction from immediately below the bottom edge of the diagonal fold lines (L1a, L1b).
