PROBLEM TO BE SOLVED: To provide a tank capable of reducing its weight while securing powder and grain loading capacity. SOLUTION: The tank 1 is formed to have a shape in which large diameter openings 2a, 3a of circular truncated cone shaped front and rear cylinders 2, 2 confront each other. This shape can reduce the capacity of a dead space on which powder and grain cannot be loaded, and thus, the size of the tank 1 can be reduced. Therefore, while the powder and grain loading capacity is secured, the tank weight can be reduced. COPYRIGHT: (C)2008,JPO&INPIT
