Abstract
A pump intended to be mounted on a bottle, so as to allow the dispensing of a liquid contained in the bottle, includes a needle for closing an ejection orifice that is separate from a dosing sleeve. The needle is mounted on the sleeve by a device for the reversible movement of the needle between a closure position and an ejection position, the device being actuated by interference between the sleeve and a piston when a push button is moved on a hoop.
