An opening 6 narrowed as it goes from the outer ends 13A and 13B of the volume part 4 to the inside of the volume part 4 is provided in the volume part 4. The mouth 2A of the bag, whose diameter is squeezed, is taken in and out through the opening 6 and the volume part 4 including the opening 6 being in an open state hooks the mouth 2B of the bag, whose diameter after insertion into the volume part 4 is broadened. The first member 95zz and the second member 94zz are locked with each other, to seal the mouth 2 of the bag inserted from the opening 6 by the first member 95zz and the second member 94zz. |
