DRIPPER

PROBLEM TO BE SOLVED: To provide a dripper which can maintain an opening of a fixed size and be assuredly mounted and fixed on a cup wall to pour hot water with ease. SOLUTION: In the dripper formed by inserting a bag with percolation function into a tubular paper body of a rectangular shape in plan view with a folding in both sides and sticking approximately central facing sections of the opening edge of the bag on an approximately central section of one opening edge of the tubular paper body, a pair of central engaging projections and side engaging projections are formed on the other opening edge of the tubular paper body. Besides, a pair of second tangential lines which divide the pair of the central engaging projections roughly equally from another opening edge of the pair of central engaging projections, and extend to one opening edge side, and a pair of first tangential lines which extend from each end of one opening edge side of the pair of the second tangential lines to both side edges to the second tangential lines symmetrically are formed.
