Abstract

The invention relates to fluid dispensers (10) comprising a container (20) consisting of an elastic material, which is designed to hold a fluid and is held under tension when filled, said tension causing the fluid to be discharged from the container (20). The invention is characterised in that the tension of the container (20) can be adjusted by the predefined regulation of an internal tension of the material of the container (20), by the exertion of a force on the exterior of the container (20) and/or by the enlargement of at least one internal expansion body (30) in the container (20). Said internal expansion body (30) comprises a material, whose volume can be adjusted to a specific value by a reaction that is triggered externally. The invention also relates to methods for operating fluid dispensers of this type.
