Abstract
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 spaced apart from each other with a bag main body width center line between them. Each hooking portion extends downward and is 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 edge fixed onto the bag main body at a lower part. The fixed edge 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.

- an upper bonded portion provided along an upper side of the bag main body;
- a central portion provided in a center of each of the hooking members, the central portion being unable to be pulled up from the bag main body;
- a pair of arm portions provided from the central portion to a direction toward the upper bonded portion, the pair of arm portions being spaced apart from each other with a center line of a width of the bag main body located between them;
- and
- a pair of hooking portions, each hooking portion among the pair of hooking portions being continuous with an upper part of a respective arm portion among the pair of arm portions, each hooking portion extending downward from the upper part of the respective arm portion, the pair of hooking portions being not bonded onto the bag main body, wherein:
- each arm portion among the pair the arm portions is capable of being pulled up from the bag main body at an upper part thereof, each arm portion among the pair of arm portions has a fixed edge fixed onto the bag main body at a lower part thereof, the fixed edge is adjoined to the upper part that is capable of being pulled up from the bag main body, and the fixed edge is inclined with respect to a width direction of the bag main body or extends downward vertically with respect to the width direction of the bag main body from a lower end of a side, farther from the center line, out of left and right sides of the respective arm portion among the pair of arm portions;
- and
- the fixed edge is defined between:
- a bottom end of the left side of the respective arm portion among the pair of arm portions and
- a bottom end of the right side of the respective arm portion among the pair of arm portions.
