  • Patent number: 9091671
    Abstract: Arrangement enables liquid suction with a nozzle tip end in contact with a container bottom without causing damage to the nozzle and/or container bottom. Plural rails are disposed to extend upward from an arm which is movable three-dimensionally, so as to extend upward from the arm, and a pipe is fixed to a pipe fixing member movable along the rails. A pipe tip end functions as a nozzle. Plural resilient members disposed on the arm correct the inclination of the pipe fixing member. When the arm is moved downward and the tip end comes in contact with the bottom of the container 106, the pipe and the pipe fixing portion move upward along the rails, so that the pipe tip end can be brought into contact with the bottom surface of the container while avoiding damages in the pipe and container bottom, and to suck liquid in the container.
