Abstract: An inhalation spacer movable between a collapsed configuration and an expanded configuration. The spacer is made from paperboard having a bending stiffness of at least 2.5 mNm.

Abstract: An aerosol canister for dispensing a product and propellant, and a product metering valve for use with the aerosol canister. The canister includes a high pressure chamber for containing a liquefied or compressed gas propellant, a low pressure chamber for containing a gas propellant, and a product reservoir for containing a gas propellant. A pressure regulating valve is interposed between the high pressure chamber and the low pressure chamber, the pressure regulating valve adapted to provide a fluid flow path from the high pressure chamber to the low pressure chamber when the pressure in the low pressure chamber drops below a predetermined pressure. The canister further includes a partition wall interposed between the low pressure chamber and the product reservoir.

Abstract: A canister for a metered dose inhaler has high and low pressure chambers for a propellant and for an inhalable drug and vaporised propellant. The low pressure chamber has an opening for a metering valve. A pressure regulating valve is between the high and low pressure chambers and provides a flow path from them. A metering valve dispenses a metered dose. The valve includes a metering valve body having a propellant metering chamber with a propellant inlet and a product metering chamber with a product inlet, and a metering valve stem with a dispensing nozzle, a propellant inlet plug and a product inlet plug. The metering valve stem moves to a dispensing position. In the dispensing position, the propellant and product metering chambers are in fluid communication with atmosphere via the dispensing nozzle of the metering valve stem such that a metered dose of product and propellant can be dispensed.
