    摘要： A drip bag is devised so that the good taste of coffee made by a conventional paper drip system can be obtained using a simple construction, and so that the drip bag can be set easily and securely on the cup even in cases where the thickness of the walls of the opening part of the cup is large. The drip bag includes a bag main body which is made of a water-permeable filtering sheet material and which has an opening part in the upper end portion of said bag main body, holding members which are made of a thin sheet-form material and which are disposed on the outside surfaces of two opposite sides of the bag main body, and reinforcing parts which are made of a thin sheet-form material and which are pasted to the outside surface of the bag main body around the peripheral parts of the holding members. Each of these holding members is formed from a tongue part which is pasted to the outside surface of the bag main body, an arm part which is located on the periphery of the tongue part, which is continuous with the lower end of the tongue part and which is formed so that said arm part can be pulled out from the bag main body, and a peripheral edge part of a specified shape, which is located on the periphery of the arm part and which is continuous with the central portion of the upper end of the arm part.
