<P>PROBLEM TO BE SOLVED: To provide a dripper which maintains an approximate constant shape of a transverse section (degree of opening) when retaining a cylindrical shape and enables a user to pour hot water without worrying about the shape of the transverse section (degree of opening) getting smaller at the time of brewing. <P>SOLUTION: The dripper comprises a cylindrical paper body, equipped with folded parts on both side edges and a pair of opposing protruding flaps in the central parts between both side edges and having a rectangular shape in a plan view, and a pouch body with a filtering function. Central opposing parts of the opening edge of the pouch body inserted in the cylindrical paper body are stuck to the pair of the protruding flaps of the cylindrical paper body, and an opening part of the pouch body is detachably closed after accommodating the contents. The dripper has opposing, straight slit parts, which never intersect the upper and lower end edges of the cylindrical paper body and are in parallel with both end edges, in positions dividing the distance between both side edges of the cylindrical paper body into three. <P>COPYRIGHT: (C)2004,JPO |
