A discharge device for discharging a fluid product or a powder product, a discharge head (1) having a discharge port (10) formed at an end of a hollow sleeve (3), and a rest position in an air chamber (22) And an air delivery device (20) for generating an air flow during operation of the discharge device, and a container (30) for storing a single product. And the mechanical opening system (61, 62) and the discharge device to the user by transitioning to a second state that is in a visible state at the rest position before the operation and in an invisible state after the operation. A notification unit (100； 50) for notifying that the air chamber has been operated, and a pusher element (25) fixed to the piston (21) and pressed by the user during operation, wherein the air chamber (22) Piston (21 Has a cylindrical body that slides inside in an airtight state, and the container (30) is connected to the air delivery device (20) to hold the product in the container (30) until discharging. An air inlet (31) in which a product holding member (40) is disposed, and a product outlet (32) connected to the discharge port (10) and closed by press-fitting a closing element (50). The mechanical opening system (61, 62) cooperates with the closing element (50) during operation of the discharge device to mechanically push out the closing element (50) from a closed position, (1) Discharge device having a skirt portion (5) disposed around the air chamber (22) and having a notch (6) at the lower end in the axial direction.
