To provide a liquid subdividing device 20 with a simple mechanism, which handles subdividing containers 10 in various sizes.

In the liquid subdividing device, a container accumulating portion 22 holds many subdividing containers 10, the overhang parts 12 of which are of the same shape and the depth of the container bodies 11 of which are different, and a single container holding portion 30 holds one of the subdividing containers 10 by inserting a container body 11 into a hollow portion 31 at the center of the upper face and supporting the overhang part 12 with an edge 32 on the upper face, and a container feeding mechanism 41 transfers the subdividing container 10 to the single container holding portion 30 one by one from the container accumulating portion 22, and a liquid pouring mechanism 42 pours a liquid into the subdividing container 10 and a container sealing mechanism 44 seals the subdividing container. A plurality of single container holding portions 30 are lined and fixed on the upper face of a rotating plate 23 at an equal pitch and the container feeding mechanism 41, the liquid pouring mechanism 42 and the container sealing mechanism 44 are arranged over them and the single container holding portion 30 is sent at each pitch by rotation around the perpendicular axis of the rotation plate 23 to move to the transferring part, the pouring part and the sealing part.
