Reservoir and atomiser

摘要

The reservoir (3) has an outer shell (23) and a fluid space (4) provided with a fluid (2) i.e. pharmaceutical formulation. The fluid space is provided with a flexible or deformable wall (25) so that the fluid space collapses during removal of the fluid and/or forms a deformable inner container. The outer shell is extruded on the wall, where the wall is partially detached from the outer shell during removal of the fluid. The outer shell is made of polyethylene or polyethylentherephtalate. An outer layer of the wall is made of plastic. An independent claim is also included for a method for manufacturing a reservoir.
