The invention relates to a device for the dosed administration of an injectable product, said device comprising: a) a housing (1, 2, 3), b) a first reservoir which is formed or received by the housing (1, 2, 3), and from which a product dose is administered, c) a second reservoir (7) for the product, d) a transport device (14, 15, 16) by which means the product dose is transported from the second reservoir (7) to the first reservoir (4), e) a ventilation device (11a) for ventilating the first reservoir (4), f) a dosing and actuating device (20, 21) which is connected to the housing (1, 2, 3), and by which means, in relation to the housing (1, 2, 3), a dosing movement is carried out for the selection of the product dose, a transporting movement is carried out for the actuation of the transport device (14, 15, 16), and a ventilation movement is carried out for the actuation of the ventilation device (11a), g) a stop element (25) which is moveably positioned in the housing (1, 2, 3) and is coupled to the dosing and actuating device (20, 21) in such a way that the dosing movement of the dosing and actuating device (20, 21) causes the stop element (25) to be positioned in a stop position for the transport device (14, 15, 16), and h) a tappet (30) which is moveably positioned in the housing (1, 2, 3) and is coupled to the dosing and actuating device (20, 21) in such a way that the dosing movement of the dosing and actuating device (20, 21) causes the tappet (30) to be positioned in a stop position, and the ventilation movement of the dosing and actuating device (20, 21) causes a ventilation movement of the tappet (30) from its stop position, i) the tappet (30) entraining the ventilation device (11a) in its ventilation movement, ventilating the first reservoir (4).
