Since the discharge hole 24 is arranged downward and the through hole 25 is arranged upward when the contents Y are filled in the container, the contents Y are accumulated in the rotor 21 as the contents are completely filled in the through hole 25. A space H is generated in the reservoir 22 of the rotor 21 without being filled in the portion 22. Therefore, even when the density of the contents Y is partially increased at the beginning of filling the rotor 21, the contents Y in the storage part 22 are stored in the storage part 22 when the discharge hole 24 communicates with the measurement recess 50 and the rotor 21 rotates. The contents are swayed to have a uniform density, and the contents Y having a constant density are further filled in the measuring concave portion 50.

In the embodiment, the case where the packaged product W consisting of the three packages B is manufactured has been described.
The present invention can be applied to the production of a packaged product W composed of one, two, or four or more packages B.

Further, in the embodiment, the case where the through hole 25 and the discharge hole 24 are formed in a straight line in the storage portion 22 provided in the rotor 21 is shown, but of course, the through hole 25 is formed with respect to the discharge hole 24. It may be configured to be bent.

By the way, when the through hole 25 and the discharge hole 24 are formed in a straight line, it is convenient to empty the contents Y in the hopper 2. That is, as shown in FIG.
After removing the hopper 62 and the support bracket 63 of the filling section 61, the storage box 96 is placed on the wrapping paper forming device M2, and the through holes 4a of the partition plate 4 are connected to the through holes 3b of the mounting plate 3.
And each through hole 53a of the shutter 53
Are aligned with the respective measurement recesses 50, and the discharge holes 2 of the rotor 21 are
When 4 is aligned with each of the measuring recesses 50, the contents Y are transferred to the through holes 3b, 4a, 10, 25, the discharge hole 24, and the measuring recess 50.
It can be stored in the storage box 96 via the through hole 53a. In this way, if the contents Y in the hopper 2 can be easily removed, a packaged product W in which the contents Y are changed is produced, or in the case of the contents Y that dislike moisture, the next day after the work is finished. The contents Y up to the above can be easily stored, which is more convenient than the case where the contents Y are taken out from above the hopper 2 with a ladle or the like.
