PURPOSE:To sufficiently secure the shape of a filter when hot water is poured in and to attain high-level stability by providing support planes for forming V-notch on the front and rear external sides. CONSTITUTION:An engaging member 11 formed on the lower end of a vertical side plane 6, 6 of a holder 1 is placed inside of a cup 3 and mounting member 10 is placed on the periphery 3a of a cup 3. A spread filter 2 is fit into a V- notch by adjusting it to the vertical direction of a holder 1 so as to coincide with the longitudinal direction. Four sheets of support planes 9, 9 support a sectional reverse cone-shaped filter 2 from its right and left sides. A proper amount of coffee powder is placed into the filter 2. When hot water is poured into the filter 2, the filter 2 will tend to be distorted. However, the four sheets of support planes prevent the distortion, and stability of the filter holding hot water is maintained. The weight of hot water in the filter 2 works to spread the filter to the outside, but since an engagement member 11 is fit into the periphery 3a, the holder body is not removed from the cup 3. |
