In the method for venting and eliminating liquid material of a dispensing appliance prior to dispensing, the air as well as unusable material are eliminated via a deviating channel and the conditioned material is dispensed via a dispensing channel. The device for implementing the method for eliminating unusable liquid material and for venting a dispensing appliance is provided with a valve assembly for selectively connecting the inlet area of the device with a deviating channel or with an outlet. The deviating channel is connected to a collecting container having venting means. The method and the device according to the invention allow advantageously venting a multicomponent dispensing appliance and leveling the components as well as eliminating incompletely mixed components in the starting phase after the latter have left the mixer elements, thereby ensuring a flawless application. In an advantageous development, a device is provided that avoids the occurrence of an overpressure during dispensing.
