A manually operated dispensing device for use with a double cartridge for dispensing two-component chemical systems includes a double thrust ram with two thrust ram parts each having a toothed surface on which teeth are provided. The width of the thrust ram parts may be equal, or alternatively, the one thrust ram part may be wider than the other. The dispensing device further includes a drive assembly for acting on the double thrust ram, which is actuated by a trigger lever. The drive assembly includes a drive member, which includes teeth for acting on the teeth of the double thrust ram. The toothed surface of the thrust ram parts are either provided with ribs arranged near the outer edges of the thrust ram parts or have no ribs at all. As a result, a maximum width of the teeth is obtained and a maximum force is transmitted.
