To secure a sealing property during a storage time of an advancing container and improve operability at the start of using the container by modifying positional deviation circumferentially between a cylinder body and a receiving pan during the storage time.

A feeding container is configured of the elliptic cylinder body 1, the receiving pan 21 having a cylinder shape with a noncircular cross section which elevates and lowers in a storage cylinder 2 of the cylinder body 1 so as to be non-turnable, and a drive body 11 which is non-lowerlingly installed to the cylinder body 1 in a non-elevating manner so as to be turnable, and is screwed to the receiving pan 21. A seal part 3 of the lower end of the inner circumferential surface of the storage cylinder 2 and the seal cylinder 24 of the lower end of the receiving pan 21 are made to be tightly fitted to each other. An alignment function part for forcibly modifying deviation between the cylinder body 1 and the receiving pan 21 circumferentially by engagement is arranged between the lower end of the storage cylinder 2 and the lower end of the receiving pan 21. During the storage time, an alignment state is maintained without fail.
