It is made to flow into the storage part of the rotor through the communication hole.

[0010] Thereafter, the rotor is rotated to make the opening of the storage portion coincide with the measurement concave portion. Then, the content stored in the storage part of the rotor is filled in the measuring concave part.

Then, the rotor is rotated to make the opening of the storage portion coincide with the communication hole, and the content filled in the measuring recess is cut off on the outer peripheral surface of the rotor.

Then, the shutter below the measuring recess is opened,
If the content measured by the volume of the measurement concave portion is allowed to fall naturally into the filling portion and the above-described steps are repeatedly performed, a packaged product can be sequentially manufactured.

That is, in the measuring and filling device according to the present invention, the measuring recess is not formed in the rotor itself, and the hopper and the measuring recess are separated by the rotor, so that the measuring recess is filled. The contents are not affected by the amount stored in the hopper.
