Abstract:
1. A method for discharging a fluid product from a container through an outlet in the container, the method comprising the steps of: arranging a plunger remote from the outlet inside the container, wherein a total advancing distance is defined by a maximum distance the plunger can travel within the container in the direction of the outlet; arranging a drive device in a housing proximate the plunger, the drive device comprising: advancing the plunger in the direction of the outlet under the force of the drive device, by each of the first partial advancing distance and the second partial advancing distance which is shorter than the total advancing distance; and after or during the advance of the advancing element over the first partial advancing distance and the second partial advancing distance, tensioning the spring device by the first and second tension distance set by translational movement of the tensioning element relative to the housing.
