PURPOSE:To enable to take out liquid in a container in a repeated manner without causing intrusion and discharge of air, by retaining the liquid in the siphon from pipes attached to the opposite ends of the siphon. CONSTITUTION:When a siphon is lifted by holding a knob after filling the siphon with a liquid, the liquid is not discharged to the outside by air introduced therein since points A, B are located at positions higher than those of points C, D. When a pipe 6 is immersed in a container and the level of liquid in the container is higher than the point A, the liquid flows through the siphon. However, when the level of liquid in the container becomes lower than the point A, the liquid flow is stopped. Here, since the liquid is left in the siphon, liquid flow can be caused in a repeated manner. |
