Abstract
A drive device for advancing an advancing element () relative to a housing () over a entire advancing distance (G) comprises a tensioning device having a tensioning element () for tensioning a spring device (). A predetermined distance (A) between the tensioning element () and the advancing element () or between the counter element () and the tensioning element () that engages with advancing element can be set according to the advancing of the advancing element () by a partial advancing distance that is less than the entire advancing distance (G). According to a method for discharging a fluid product from a container () via an outlet (), a plunger () is displaced inside the container () by means of a drive device provided with an advancing element () and with a spring device (), whereby the spring device () is tensioned by a tensioning device according to the advancing of the advancing element () by a partial advancing distance.
