  • the provision of the restricting portion allows the solution to be drawn out of the suction pipe vigorously, so that the solution does not sag at the discharge end of the suction pipe, and has the effect of being easy to use. Even if the valve and the check valve are opened when the container equipped with the valve falls, there is a merit that the solution can be prevented from flowing out to the outside by the throttle.

Therefore, there is an effect that cost can be significantly reduced.
  • the valve of the valve or the check valve is configured to prevent the solution from flowing backward. Then, since the bowl-shaped portion receives the pressure of the solution and quickly moves the valve body in the closing direction, there is an effect that the valve closing operation of the valve body is surely performed.
  • valve unit of the present invention by providing the bowl portion with the rod portion, there is an effect that the posture of the bowl portion can be stabilized.
