A dispenser device for fluid or powder, including an air expeller (20) and a reservoir (30). The reservoir (30) has an air inlet (31) connected to the air expeller (20) and a composition outlet (32) connected to a dispenser opening (10), and is removably mounted on the air expeller. After actuation, the empty reservoir can be removed from the air expeller and replaced with a new reservoir. The air inlet (31) is closed by a first closure element (40) and the composition outlet (32) is closed by a second closure element (50). A mechanical opening system (61, 62) co-operates with the first and second closure elements to expel each closure element from the closed position. The mechanical opening system has a first rod (61) secured to the air expeller (20), and a second rod (62) secured to the dispenser head (1), co-operating with a closure element during actuation.

Fluid delivery devices and methods are described where the device may comprise a piezoelectric actuator having a piezoelectric chip that is operatively coupled to a drug package under a preloading force. The actuator is configured to generate an acoustic pressure within the drug package to dispense droplets or a continuous stream of an agent from an aperture, e.g., to the corneal surface of the eye. The piezoelectric actuator can be coupled or decoupled from the drug package via a coupling mechanism which enables the quick release and consistent securement of the drug package to the actuator and housing.

A nicotine particle delivery consumable article includes a receptacle having a body extending from a receptacle first end to an opposing receptacle second end and defining a cavity. A capsule is disposed within the cavity. The capsule contains particles including nicotine. The receptacle includes a membrane sealing the receptacle first end and an air outlet extending through the receptacle second end and into the cavity. An air inlet, close to the receptacle first end, extends through a side wall of the body and into the cavity.

A valved container assembly has a container for containing a fluid, extending in an axial direction, and having an open front end and a valve disposed in the container. A plunger element is disposed axially rearward of the valve and is axially moveable in the container. The plunger element is configured to increase the pressure of a fluid in a first volume of the container upon axial movement of the plunger element relative to the valve. The valve includes a channel bypassing a seal, the channel having a first opening in fluid communication with the atmosphere outside of the valved container assembly and a second opening selectively sealed from the first volume by a resilient seal. The resilient seal is moveable from a sealing configuration to an open configuration upon the pressure of the fluid in the first volume exceeding a first pressure threshold.

An inhaler for facilitating inhalation of dry powder includes a body defining an interior space and a mouth piece. At least one annular member is positioned within the interior space and is rotatable with respect to the mouth piece. The at least one annular member includes a plurality of compartments. Each compartment defines a cavity configured to hold dry powder. Each compartment includes at least one flap and an opening configured to release the dry powder when the at least one flap is reconfigured from a closed position to an open position. The at least one flap covers the opening and inhibits the dry powder from being released from the cavity in the closed position.

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing having a first housing end and a second housing end opposite the first housing end, an airflow tube that extends through the reservoir housing, and first and second seals that are each substantially impermeable to fluid, in which the first seal is substantially secured to the first housing end and the second seal is substantially secured to the second housing end. The reservoir housing is configured to hold vaporizable material and the first and second seals are configured to be selectively compromised to allow access to the vaporizable material within the reservoir housing for vaporization into vaporized material. Vaporizer devices are also provided.

A dose ring for a dry powder inhaler (DPI) device includes an aluminum foil member covering particulate medication cavities and through holes. The device includes hinged flaps formed by a cut so that one radial side is uncut and forms a hinge. Each flap can cover both a cavity for particulate medication and a through hole located between that cavity and the circular inside edge of the dose ring.

The integration of drug dispersion methods into a drug or medicine delivery system may use shear (e.g., air across a drug, with or without a gas assist), capillary flow or a venturi effect, mechanical means such as spinning, vibration, or impaction, and turbulence (e.g., using mesh screens, or restrictions in the air path). These methods of drug dispersion allow for all of the drug in the system to be released, allowing control of the dosage size. These methods also provide for drug metering, fluidization, entrainment, deaggragation and deagglomeration. The integration of a drug sealing system into the device provides a way of blocking the migration of drug from one area of the package to another. The drug seal system can also provide a method of tightly containing the drug until the package is opened, of directing airflow through the package and of managing and containing the drug during the package/device manufacturing process.

Dry powder inhaler systems for pulmonary delivery of pharmaceuticals are disclosed.

The present invention relates to a low-cost single-use disposable breath actuated dry powder inhaler, its method of use, and method of manufacture. The inhaler comprises a bottom layer and a top layer. The inhaler comprises a medicament compartment and an air passageway. Furthermore, the medicament compartment is sealed by a flexible pull tab that is easily removed before use, and the air passageway comprises a mouthpiece port, a Venturi section, and an air inlet port.
