A nebulizer for a fluid, includes a container containing the fluid; a housing part which can be detached from the nebulizer for replacing the container; an inner part; a retaining element connected with and not detachable from the inner part, where the housing part is releasable fixed to the inner part by the retaining element; a delivery mechanism for dispensing the fluid; a manually depressible actuator member, which is a separate part from the retaining element and acts on the retaining element, and wherein the actuator member is depressed to elastically deform or flex the retaining element to allow detachment of the housing part.

An inhaler device includes a sealed elongated body having air inlet and mouthpiece ends, a first end-seal sealing the air inlet end, a second end-seal sealing the mouthpiece end, and passive evaporation support material pre-loaded with methoxyflurane liquid. As the methoxyflurane liquid forms a vapor, the elongated body forms a vapor chamber such that the stored vapor is available for direct administration upon opening the first and second end-seals. The first end-seal is a resealable, adjustable end cap with an air inlet groove or hole that forms an air inlet opening when opened such that the air inlet's size is adjustable. The second end-seal is a resealable, adjustable end cap including a mouthpiece chamber configured such that when closed the vapor chamber is sealed from the mouthpiece chamber and when open vapor flows radially inward into the mouthpiece chamber through vents located in a side wall of the mouthpiece chamber.

A fluid dispenser device including a body; a reservoir containing one or two doses of a fluid, the reservoir including a stopper that closes the reservoir in leaktight manner before actuation; a dispenser head that is provided with a dispenser orifice; and dispenser mechanism for dispensing at least a portion of the fluid through the dispenser orifice during actuation. The device further includes a needle having a tip that is adapted to pierce the stopper during actuation, the reservoir being filled with the fluid and being closed with the stopper under a vacuum, so that the residual volume of air present in the reservoir between the fluid and the stopper is substantially zero.

An aerosol generating apparatus includes a vial, a cap assembly and a receptacle. The vial stores liquid medicament and includes a puncturable seal held in position by a retaining ring. The cap assembly includes an actuator with an interior bore extending therethrough, a perforated membrane coupled to the actuator, a fastener and a first mating element. The fastener is adapted to detachably secure the cap assembly to the vial such that the perforated membrane aligns with the puncturable seal. The receptacle receives the cap assembly with the vial. The receptacle includes a driving element and a second mating element capable of mating with the first mating element. The driving element aligns and communicates with the perforated membrane when the receptacle engages the cap assembly. The actuator pierces the puncturable seal to displace the liquid medicament through the interior bore to the perforated membrane and the driving element to generate aerosol.

An aerosol-generating system may include a liquid storage portion, a vaporizer, and a pump. The liquid storage portion may be configured to store a liquid aerosol-forming substrate. The vaporizer may be configured to volatilize the liquid aerosol-forming substrate. The pump may be configured to pump air into the liquid storage portion so as to push out a volume of the liquid aerosol-forming substrate from the liquid storage portion and to supply the volume of the liquid aerosol-forming substrate to the vaporizer. A method for generating an aerosol may be performed with the system.

Device for dispensing a fluid product, having a body, a reservoir containing one or two doses of a fluid product, the reservoir having a stopper that closes off the reservoir in a sealed manner before actuation, a dispensing head provided with a dispensing orifice, and an actuating mechanism for dispensing at least a portion of the fluid product through the dispensing orifice during actuation. The dispensing head receives an insert having a channel that connects, during actuation, the reservoir to the dispensing orifice. The stopper has a hollow axial sleeve suitable for sliding within the reservoir during actuation, the hollow axial sleeve being closed off before actuation by a deformable radial membrane. The insert has a point suitable for piercing the membrane of the stopper at the time of actuation, and a piston suitable for sliding in a sealed manner within the reservoir during actuation.

A dry powder inhaler (10) having a chamber (26) divided into first and second blister compartments (28, 30) for storing unused and used portions (34, 36) of a blister strip (12) is provided. A moveable dividing wall (32) separates the first and second blister compartments. One or more arcuate supporting surfaces (38, 40, 42) are disposed in either the first and/or the second blister compartments and these surfaces support the used or unused blister strip during successive actuations of the inhaler. Use of the arcuate supporting surfaces facilities compact coils of unused and used portions of blister strip, thereby reducing the size of the chamber required for the inhaler.

This disclosure relates to flavoured nicotine powder inhalers where the nicotine powder is delivered at air flow rates that mimic a smoking regime.

An electrically heated aerosol-generating device includes a storage portion configured to contain an aerosol-forming substrate and having a fluid permeable internal surface surrounding an open-ended passage extending through the cartridge. The device includes a housing having a cavity for receiving the cartridge, and a heater assembly positioned in the cavity. The heater assembly includes an elongate support member connected to the housing and arranged to extend into the open-ended passage of a cartridge inserted in the cavity. The heater assembly also includes a plurality of electric heaters fixed to and spaced along the length of the elongate support member.
