The invention relates to a device (1) for dispensing a substance (27) which can be discharged by air, comprising a discharge nozzle (15), a pump device, an air guiding channel (14) joining the pump device to the discharge nozzle (15), a strip-shaped element (25) which is mounted in the device (1) and which comprises chambers (26) which contains the substance (27) and which are embodied successively over the entire length in the strip-shaped element (25), a reservoir (45) and an emptying region (46), the strip-shaped element (25) having several layers. The second layer (28) of the chamber (26), which is located in the emptying region (46), is already removed in the partial region comprising said chamber (26) and the air subjected to the forced flow flows through the air-guiding channel merging into the opening plane (O) in the chamber, for advantageously emptying. Also, with respect to the pump device, the pump wall (32) comprises a pressure region (34) and several convex regions (35, 36) and when the convex regions (35, 36) are pressurised, the convex regions (35, 36) remain essentially the same and/or the device comprises a receiving region which is designed as a closed receiving chamber within the device, and that the partial region is located, during an anticipated movement, in the emptying region (46) forming a movable part of the wall (49) of the capture chamber (48).
