A fluid or powder product dispenser includes a dispenser head (1) having a discharge port (10) and an air supply device (20) for generating an air flow during operation. ) And. The container has an air inlet (31) connected to the air supply device and a product outlet (32) connected to the discharge port, and is detachably mounted on the air supply device so that the container is emptied from the air supply device after the operation. The container of can be removed and replaced with a new container. By returning the air supply device to the standby position, a new operation using a new container is possible. The air inlet and the product outlet are closed by first and second closing elements (40, 50), respectively. The dispensing device further comprises a mechanical opening system (61, 62) which mechanically pushes the first and second closing elements out of the closed position during operation. The system includes first and second rods (61, 62) fixed to the insufflator and the discharge head, respectively. During operation, the first and second rods mechanically push the first and second closure elements out of the closed position, respectively. [Selection diagram]流体または粉体製品の吐出装置は、吐出口（１０）を有する吐出ヘッド（１）と、作動中に空気流を生成する送気装置（２０）と、の製品を１回分収容した容器（３０）とを備える。容器は、送気装置と接続する空気入口（３１）及び吐出口と接続する製品出口（３２）を有し、送気装置上に着脱可能に装着されることで、作動後に送気装置から空の容器を取り外して新たな容器に交換できる。送気装置が待機位置に戻ることで、新たな容器を用いた新たな作動が可能である。空気入口及び製品出口は各々第１及び第２閉鎖要素（４０，５０）により閉鎖される。吐出装置はさらに、作動中に第１及び第２閉鎖要素を閉鎖位置から機械的に押し出す機械的開放システム（６１，６２）を備える。システムは、送気装置及び吐出ヘッドに各々固定された第１及び第２ロッド（６１，６２）を含む。作動中に、第１及び第２ロッドは各々第１及び第２閉鎖要素を閉鎖位置から機械的に押し出す。【選択図】 図１
