ABSTRACT:
A structure for automated sticking out and retreating a pipette of a canteen includes a canteen, a canteen cover and a turning cover. A washer is threaded to the hollow, semi-spherical canteen. A bore penetrating the center of a tangent surface at the frond end of the canteen to allow both pipette base and fixing sleeve hold the pipette in position. At one side of the bore is a hollow snapping base with a ventilation outlet on it. In the turning cover which shreds onto the canteen cover, a snapping tab is provided and said pipette sticks out of a circular opening on the turning cover whereby the snapping tab pushes against the pipette to bend into the snapping base for closing up the ventilation outlet thus to achieve a complete leak-proof result and easy operation of the canteen.
