The container 11 can be filled with the liquid L under more uniform conditions. More specifically, in the accommodating portion 11 of all the single containers 10, the liquid L flows in from one end in the width w1 direction of the bottom through the liquid passage 40, and the liquid passage from the other end in the width w1 direction of the bottom. The liquid L can be filled under the same conditions in which the liquid L flows out through the 40.

Further, the connecting container 100 of the present embodiment fills the accommodating portions 11 of the plurality of single containers 10 by filling the liquid L through the liquid passage 40 communicating with the bottoms of the accommodating portions 11 of the plurality of single containers 10. The height of the liquid level LL of the liquid L to be formed can be made substantially the same height. Therefore, when the volume of the liquid L filled in the plurality of storage portions 11 is small by making the configuration of the plurality of single containers 10 the same and making the heights of the bottom surfaces 11b of the plurality of storage portions 11 substantially equal. However, the volume of the liquid L can be distributed more evenly.
