The container body 4 has a lower outer cylindrical body 12 that makes the inside communicate downward. The inner bag 5 has the discharge cylindrical body 24 which is fitted to the inside of the lower outer cylindrical body 12 and discharges the stored object 2 downward from the inside of the inner bag 5. An inner cylindrical body 31 inserted into a gap 30 between the lower outer cylindrical body 12 and the discharge cylindrical body 24 is provided on an axis 3 of the lower outer cylindrical body 12. While one end 31a of the inner cylindrical body 31 in an axial direction is fixed to the lower outer cylindrical body 12 so as to close the gap 30, the other end 31b of the inner cylindrical body 31 in an axial direction is fixed to the discharge cylindrical body 24. <P>COPYRIGHT: (C)2012,JPO&INPIT |
