1. A dosing device for mixing an additive into a basic flow, comprising:a) a passage for the basic flow, the passage configured such that the basic flow is continuous; b) an inlet for the additive in the passage; c) a container for the additive connected to the inlet via a dosing mechanism, the dosing mechanism protruding into the passage, and the container having a controllable drive for discharge of the additive into the passage; d) weighing means for determining the weight of at least the container with the additive; and e) a control for the controllable drive which is connected to the weighing means for setting a dosed discharge, wherein the dosing mechanism is arranged on the inlet via the weighing means. 2. The device as claimed in claim 1, wherein the weighing means comprise a compensation for shifting the centre of gravity of the container with the additive therein.3. The device as claimed in claim 1, wherein the weighing means comprise a load cell.4. The device as claimed in claim 3, wherein the load cell is of the off-centre type.5. The device as claimed in claim 1, wherein the inlet comprises a neck part, through which the passage extends, and with an opening forming the inlet for loosely receiving therein an outlet of the dosing mechanism.6. The device as claimed in claim 1, wherein the dosing mechanism comprises a worm screw in a cylinder which is connected to the drive and forms a dosing cylinder, wherein the worm screw and the cylinder form a unit.7. The device as claimed in claim 6, wherein the discharge in mass per unit of time relative to the rotation speed of the dosing cylinder is non-linear and the control is configured to bring about with a collective algorithm an adjustable dosed discharge by adjusting the rotation speed of the dosing cylinder caused by the drive on the basis of determinations of weight made by the weighing means.
