RESERVOIR AND ATOMIZER

摘要

The invention relates to a reservoir and an atomizer comprising such a reservoir. The reservoir comprises a closure for a fluid space with a drug formulation, which is formed by two closure parts which are welded to one another. The closure comprises a particle barrier for preventing the penetration of any welding particles into the fluid space, which are potentially produced during welding of the two closure parts. The fluid space is enlarged, preferably in the shape of a beaver tail, and is longitudinally closed with an additional material strip.
