Abstract: A canister for use in metered dose inhalers and fitted with a metering valve has walls that are formed of a laminate that includes a first layer which is composed of a metal and a second layer which is composed of a strengthening material.

Abstract: An aerosol dispenser is provided which comprises a body (1), a closure (2) sealed to the body (1), and means (7) for dispensing material from the interior of the dispenser. The closure (2) is welded to the body (1) by a metal-to-metal weld. Preferably the welding is carried out ultrasonically. A method for assembling the aerosol dispenser is also provided.

Abstract: A canister for a metered dose inhaler having part or all of its internal surfaces coated with one or more fluorocarbon polymers, optionally in combination with one or more non-fluorocarbon polymers, said canister having a wall with a thickness in the range 0.55 mm to 1.00 mm.

Abstract: A canister suitable for use in metered dose inhalers and fitted with a metering valve characterised in that its walls are formed of a laminate comprising a first layer which is composed of a metal and a second layer which is composed of a strengthening material.

Abstract: The invention is directed to a valve for an aerosol container for dispersing a suspension or solution of a medicament in a liquid propellant contained therein. The valve comprises a valve body defining an aperture, a seal mounted at the aperture, and a valve stem having a dispensing passage. The valve stem being slideably moveable through the seal such that in a first position the valve is closed to prevent the medicament and propellant from entering the dispensing passage. The valve stem also being such that in a second position the valve is open to allow the substance to be dispensed through the dispensing passage. The valve stem characterized in that it is constructed from a mouldable plastic and a mouldable lubricant.
