The present invention relates to a device (1) for discharging a substance (27) which can be expelled by air with a discharge nozzle (15). a pumping device, an air duct (14) connecting the pumping device to the discharge nozzle (15), a strip element (25) disposed in the device (1) with chambers (26) formed along the length in succession of the strip element (25) containing the substance (27), with a storage area (45) and an emptying section (46), wherein the strip element (25) is formed in multiple layers. For advantageous emptying, it is envisaged that in the case of a chamber (26) located in the emptying section (46), the second layer (28) is already removed by the partial area of that chamber (26) and the air subjected to it. Forced flow specifically flows through the air conduction channel passing through the aperture plane (o) into the chamber and into the chamber (26). as regards the pumping device, it may be provided that the pumping wall (32) has a pressurization area (34) and a plurality of arcuate areas (35, 36) and the arched areas (35, 36) remain virtually undisturbed during a pressurization, and / or the device has a collection area that is aligned like a closed collection chamber within the device and forms during anterior movement in the partial area that is located in the emptying section ( 46) a movable part of a wall (49) of the collection chamber (48).a presente invenção refere-se a um dispositivo (1) para descarregar uma substância (27) que pode ser expelida pelo ar com um bocal de descarga (15), um dispositivo de bombeamento, um canal de condução de ar (14) que conecta o dispositivo de bombeamento ao bocal de descarga (15), um elemento em forma de tira (25) disposto no dispositivo (1) com câmaras (26) formadas ao longo do comprimento ao longo sucessivamente no elemento em forma de tira (25) que contém a substância (27), com uma área de armazenamento (45) e uma seção de esvaziamento (46), em que o elemento em forma de tira (2
