FILLING/SEALING DEVICE FOR CONTAINER

A filling device with a filling failure is identified less costly, and the filling amount by the filling device is adjusted quickly. The filling/sealing device includes a filler 2 including a filling turret 20 having a plurality of holding parts 2P and a filling device 21 provided for each of the holding parts 2P to fill a container with a liquid content, forwarding turrets 4A and 4B that hold and turret-convey a container W transported from the filling turret 20, a sealing device 3 that seals the container W transported from the forwarding turrets 4A and 4B with a lid, an inspection device 50 provided in the path, in which the container W is held and turret-conveyed, to inspect a filling amount in the container W, and a controller 6 that identifies a filling device 21 with a filling failure on the basis of an inspection result from the inspection device 50 and controls the filling amount by the filling device 21.
