PURPOSE:To provide a convenient filtering paper cup for quickly separating solid and liquid. CONSTITUTION:A filtering paper cup 1 is composed of a cylindrical paper 2 coated with a thermal fusion resin on the inner surface thereof and a bottom material 3 made of nonfabric of thermal fusion resin. That is, an erected part 4 of the material 3 is heat-sealed on the lower inside of the paper 2 for bonding each other. Since the material 3 made of nonfabrics drops the liquid in the mixture of solid and liquid quickly, filtering can be made conveniently and quickly. |
