The operation of (A1) will be described. First, in the opening / closing member (2), the valve body (22) is pressed and closed at the distal end opening (21as) of the outer cylindrical body (21). When the suction means is operated in this state, the inside of the raw material container (1) is exhausted through the suction pipe (13) and the gap formed between the opening / closing member (2) and the discharge pipe (12) ( Inhaled through t1). At this time, since the exhaust volume is set to be larger than the intake volume, the inside of the raw material storage section (1) has a slight negative pressure, and as a result, as shown in FIG.

Since the valve body can close the discharge cylinder part, even if the powdery and granular material adheres to any of the valve body, outer cylinder and discharge cylinder part of the opening / closing member, if the suction operation is performed, it flows through the gap. As a result, the valve body can always close the outer cylinder body, and therefore can always reliably close the discharge cylinder part.
