Abstract
In the case of a drip irrigation tube the dosing elements which are inserted therein and are connected to the walling of the drip irrigation tube each comprise inlet regions, dosing regions and outlet regions, through which the water issues out of the drip irrigation tube via outlet openings installed in the tube walling. The outlet openings are in the form of a slit, the edge regions of the slit are supported by supporting means in such a manner as to limit bending of the edge regions of the slit towards the dosing elements. As a consequence, when negative pressure prevails in the tube contaminants are prevented from being able to penetrate through the slits into the dosing elements and block same.
