Abstract: A dose counter for an inhaler, the dose counter having a display tape arranged to be incrementally driven from a tape stock bobbin onto an incremental tape take-up drive shaft, the bobbin having an internal bore supported by and for rotation about a support shaft, at least one of the bore and support shaft having a protrusion which is resiliently biased into frictional engagement with the other of the bore and support shaft with longitudinally extending mutual frictional interaction.

Abstract: An incremental dose counter for a metered dose inhaler having a body arranged to retain a canister for movement of the canister relative thereto, the incremental dose counter having a main body, an actuator arranged to be driven and to drive an incremental output member in a count direction in response to canister motion, the actuator being configured to restrict motion of the output member in a direction opposite to the count direction.

Abstract: A manually operated metered dose inhaler includes a dose counter chamber including a dose display tape driven by a ratchet wheel which is driven in turn by an actuator pawl actuated by movement of a canister, the tape unwinding from a stock bobbin during use of the inhaler, a rotation regulator being provided for the stock bobbin and including a wavelike engagement surface with concavities which engage against control elements in the form of protrusions on resilient forks of a split pin thereby permitting incremental unwinding of the stock bobbin yet resisting excessive rotation if the inhaler is dropped onto a hard surface.

Abstract: An inhaler, such as a breath-actuated metered-dose inhaler, for delivering medicament to a patient. The inhaler includes a housing for holding the medicament and having an air inlet and a medicament delivery port which together define an air flow path into which the medicament is dispensed. The air inlet includes an array of elongate apertures formed in the housing, the long sides of adjacent apertures facing each other. Each aperture is provided with a respective different opening in an outer surface of the housing. The opening of each aperture extends in two different planes such that, if at least a part of the opening is covered in one of the two different planes during inhalation by the patient, a void space is created between the cover and the aperture so as to provide an air flow path through the void space to the at least one aperture.

Abstract: This invention relates to a pressurised metered dose inhaler comprising a canister, wherein the canister contains a formulation comprising a tiotropium salt and an HFA propellant, wherein the inhaler is an inhalation-actuated inhaler.

Abstract: An inhaler including a medicament-containing vessel; an actuator body for receiving the vessel and having a medicament delivery outlet, wherein the vessel is releasably attachable to the actuator body; a dose counter integrated into the actuator body; and a first indicium on the vessel and a second indicium on the actuator body, wherein the first indicium and the second indicium identify the vessel and the actuator body to be part of the same metered-dose inhaler. Also provided is a kit including the metered-dose inhaler and at least one pair of stickers and a method for manufacturing the metered-dose inhaler.

Abstract: An inhaler for administering a predetermined dose of a medicament. The inhaler includes a screw-threaded mechanism which is operable to dispense the predetermined dose for inhalation. The inhaler can include a rotatable threaded member mounted within a casing. The inhaler can also include an internally threaded sleeve mounted on the rotatable threaded member. The sleeve can be moved linearly by rotation of the threaded member. Medicament can be provided in a tray of the sleeve, and can be aligned with a mouth piece of the inhaler for inhalation by the linear movement of the sleeve.
