An ejection device (11) for containers containing compounds has a receiving chamber (12) for the container, a piston rod (13) which is displaceable relative to the receiving chamber (12), and an ejection unit (16) having a housing (17), a forward feed element (18) which is pivotally supported in the housing (17) for advancing the piston rod (13), and a handle (19) with an actuation lever (21) which is pivotal around an axis of rotation (22) and which has an effort arm (25) with a hand grip and a load arm (24). Pressure transmission means (23) is provided at the end of the load arm (24) facing the forward feed element (18) and can be brought into contact with the forward feed element for actuating the forward feed element (18). The length (L1) of the load arm (24), which is determined by a distance from the pressure transmission means (23) to the axis of rotation (22) of the actuation lever (21), is adjustable by displacing a bearing pin (31) that forms the axis of rotation of the actuation lever, in a guide slot provided in the actuation lever (21).
