Abstract
Abstract In the spray head for the administration of a multi-component material by means of gas, a gas channel (2) with gas connection (3) is provided, which channel is divided by a separating web (4) into a plurality of channels (2a2b) running parallel to the separating web. Into these channels there open out boreholes (5, 5a) for receiving cannulas. The open ends of the boreholes (5, 5a) go into grooves (7, 7a) which serve for guiding the cannulas (6, 6a). The grooves are arranged parallel to the gas channel (2). The separating web (4) protrudes beyond the channel ends (9, 9a).
