A device for dispensing predetermined metered quantities of liquid comprising:
- a sealing member that can take up a liquid release position allowing liquid to flow out of the device and a non-return position preventing liquid from flowing back into the device;
- a metering element provided in the sealing member for metering out the liquid to be dispensed and forming drops of liquid, wherein the metering element comprises a flared shape;
- a liquid-passing channel opening out into the metering element;
- and
- a bearing element for bearing against the sealing member in front of a recessed zone and serving to deform the sealing member so that the sealing member takes up its non-return position.
