PROBLEM TO BE SOLVED: To provide a cap which is excellent in handleability and can be used regardless of the kind of an outer container and an inner container, and a separation container kit equipped with the cap.SOLUTION: A separation container kit for separating a material to be separated from a liquid sample comprises a separation container and two caps. The separation container includes a cylindrical inner container whose upper and lower ends are opened, and a bottom-closed cylindrical outer container whose upper end is opened and whose lower end is closed, and the inner container can be inserted inside the outer container. The cap includes a first fitting part to an upper end opening of the inner container, and a second fitting part to an upper end opening of the outer container. The first fitting part is fitted to the upper opening of the inner container to bring the inside of the inner container to a liquid-tight state, and the second fitting part is fitted to the upper end opening of the outer container to bring the inside of the outer container to a liquid-tight state. Preferably the cap further has a third fitting part to a cap with the same shape and a fitted part to which the cap with the same shape can be fitted. As a result, in the case that the caps are not used, the third fitting part of one cap is fitted to the fitted part of the other cap, whereby both caps can be connected to each other. |
