<p>The object of the invention is a treatment nozzle, of which the proximal end can be connected in specific cases to a treatment container by means of a connecting element, and which comprises a connecting element being fitted with a one-way valve for letting air into the treatment device, a tubular body having at least one valve opening at its distal end, and a one-way valve adapted for letting air flow out through the valve opening, said one-way valve being disposed on the tulular body. The inventive treatment nozzle is characterised by that the one-way valve thereof is disposed on the cylindrical side wall (23) surface or the face wall (2) of the tubular body (1); or the one-way valve is made up from a valve opening (5) disposed between portions of the tubular body (1) having different geometry, preferably between portions having different diameter, and/or on a support surface located between the dome (27) and the cylindrical side wall (23) of the tubular body (1), and from a sealing element (8) adapted for sealing the valve opening (5) and being externally seated against the tubular body (1).</p> |
