For this purpose, a transportation lock is provided for the sealed container which, in the delivery state, is in engagement with the sealed container in a manner preventing the sealed container from moving axially in the nebulizer.

An inhalation device includes: a chamber for intermediate storage of an aerosol, a first connection for a nebuliser that produces the aerosol, a second connection on a patient side for delivering the aerosol, and a third connection for breathable air, where the chamber is fluidically connected in a valve-free manner on an inlet side to the first connection when the nebuliser is attached, and the chamber is connected to the third connection in parallel on the inlet side via an inlet valve so that the breathable air from the third connection flows into the chamber.

The present disclosure relates to a fluid dispensing device (1) comprising: a housing (10) to accommodate a container (110) filled a fluid, a outlet orifice (3), a discharge mechanism (130) operable for spray discharging multiple doses of the fluid via the outlet orifice (3), a mechanical energy storage (50) coupled to the discharge mechanism (130), reversibly transferable between a preloaded state and an unloaded state and configured to store mechanical energy in the preloaded state effective to produce the spray discharging of the fluid, a releasable interlock (70) configured to retain the mechanical energy storage (50) in the preloaded state, a trigger mechanism (90) operationally engageable with the interlock (70) and operable i) to release a first portion of the mechanical energy stored in the mechanical energy storage (50) when actuated for a first time and ii) to release at least a second portion of the mechanical energy stored in the mechanical energy storage (50) when actuated for a second time.

The present disclosure relates to a mechanical energy storage for a fluid dispensing device (10), the mechanical energy storage comprising:a first drive spring (51) extending along a longitudinal direction (z),the drive spring (51) comprising a first longitudinal end (53) to engage with a housing (10) of the fluid dispensing device (1) and a second longitudinal end (54) opposite to the first longitudinal end (53) to engage with a driver (30) movable relative to the housing (10) along the longitudinal direction (z),wherein the mechanical energy storage (50) is reversibly transferable into a pre-loaded state by resiliently compressing the first drive spring (51) in the longitudinal direction (z) to thereby induce a resilient deformation of the first drive spring (51) in a first direction (y) transverse to the longitudinal direction (z), and-wherein the mechanical energy storage (50) is transferable from the pre-loaded state into an unloaded state by allowing the first drive spring (51) to relax into or towards an undeformed configuration with regard to the first direction (y) accompanied by a longitudinal expansion of the first drive spring (51).

A tensioning arrangement for an aerosol dispenser is presented where the tensioning arrangement has a conveying tube; an elastic member arranged to store mechanical energy from a substantially axial tensioning movement of the conveying tube; a rotatable member; a transmission mechanism configured to transmit a tensioning rotation of the rotatable member to the tensioning movement of the conveying tube, wherein the transmission mechanism has a cam profile and a cam follower arranged to follow the cam profile, wherein the cam profile has at least one priming structure; and wherein the tensioning arrangement is configured such that the conveying tube makes a temporary priming movement towards an initial position when the cam follower passes each priming structure during the tensioning movement of the conveying tube by means of the tensioning rotation of the rotatable member. An aerosol dispenser is also provided.

A nebulizer as well as a container with a fluid for such a nebulizer are proposed. The container comprises a control device which indicates initially an unused state of the container before first use. An indicator device stops via a locking device further use of the container in a locked state when a predetermined number of uses has been reached or exceeded. After replacement of the container, the nebulizer can be reset and used again.

A reservoir for a nebulizer, and a nebulizer with a reservoir in which, to avoid undesirable rises in pressure, a fluid chamber of the reservoir is pre-collapsed and filled with an initial amount of fluid which is less than the maximum volume of the fluid chamber. Preferably, before being filled, the fluid chamber is compressed and/or expanded by means of gas to a defined volume which is less than the maximum volume of the fluid chamber.
