<p>PROBLEM TO BE SOLVED: To provide a spin-down tube which enables a user to open a lid without contaminating an exterior surface of a container body of the spin-down tube, and which allows stored liquid attached on an inner surface of a lid body to be reliably returned into the container body.SOLUTION: A spin-down tube 10 includes: a container body 1 having an aperture 5; and a lid body 2 for closing the aperture 5. The lid body 2 has an inner surface 6 being a side of the lid body 2 facing the container body 1 when closing the aperture 5, and includes a tabular projection part 3 projecting from the inner surface 6. A tip 12 of the projection part 3 projects from the inner surface in a direction directed toward the aperture 5 when the lid body 2 closes the aperture 5. Accordingly, the spin-down tube 10 solves the above described problem.</p> |
