Abstract

A nebulizer includes an insertable container and a securing mechanism for holding the container in the nebulizer such that the container can move back and forth but cannot be separated. The securing mechanism is formed by a metal unitary part. The securing mechanism forms a transportation lock for holding the container unmovable in the housing in a delivery state of the nebulizer. The securing mechanism forms a cage which encompasses the container.
