Metering valve having a valve body (10) containing a metering chamber (20) defined by a chamber insert (40) and a top and a bottom seal. The chamber insert (40) has a cylindrical wall (49) with an upper edge (41) cooperating with the top seal and a lower edge (43) with the bottom seal. A valve shut-off element (30) slides between rest position and dispensing positions. The valve shut-off element is urged towards its rest position by a spring (8) cooperating with the valve body (10) and the valve shut-off element. The lower edge of the chamber insert forms a flange and has a downward axial projection. The bottom seal has an axial opening (225) accepting an axial projection (45) and passing through the axial opening. The rest position of the valve shut-off element is defined by contact between the axial projection and a part of the valve shut-off element.

The present invention relates to a dispensing head for dispensing a metered dose of product comprising a housing which comprises a mounting assembly for mounting to a flange of an aerosol container, wherein a valve body is arranged inside the housing, with a charging system extending from the lower end of the valve body for connecting with the aerosol container valve, wherein a stem block is movably mounted in the valve body, with a head stem extending from the upper end of the stem block and passing through an opening in the top wall of the housing, wherein at least one charging opening is arranged in the central region of the valve body, wherein a dispensing container is arranged around and hermetically connected to the valve body, the dispensing container provided with resilient means for compressing the dispensing container, wherein the dispensing container is arranged in a limiting container.

The object of the invention is an aerosol metering valve system for dispensing a metered dose of product comprising: a metering chamber defined by a side wall, a top wall and a bottom wall, a charging port extending from the bottom wall of the metering chamber, a releasing stem extending from the top wall of the metering chamber, wherein the releasing stem is connected with a stem block extending towards the charging port, a piston arranged in the metering chamber and moveable in the metering chamber, a piston spring arranged in the metering chamber, resting with its one end against the piston and exerting pressure on the piston towards the charging port, wherein there is a charging channel arranged coaxially in the metering chamber, wherein the piston tightly surrounds the charging channel, wherein the charging channel has a charging opening closed by a closure and connecting the charging channel with the propulsion space under the piston and/or the charging port, and the charging channel has a dose opening connecting the charging channel with the dose space above the piston.

A metered dose inhaler valve (26) has a reservoir portion (37) for assembly with a canister (14) for receiving a pressurised formulation of medicament and propellant, a metering valve body (96) defining a metering chamber, and a metering valve stem (24) having an outlet (56) and being axially moveable within the body. The stem moves between a first position in which the chamber is in fluid communication with the canister, and a second position in which the chamber is in fluid communication with the valve stem outlet. A metering valve seal is defined by the valve body and includes an opening through which the stem passes to form a dynamic seal between the stem and at least one of the outside atmosphere and the pressurized canister, where the opening is adapted to be stretched wider by the stem passing through it than it would be absent the valve stem.

A pressurised dispensing container (10) comprising a container (11) for product to be dispensed, and a valve fixed to the container, wherein the container contains a propellant comprising 1,1-difluoroethane or a derivative thereof and optionally ethanol. The valve comprises a valve stem (15), a valve body (16, 18) and one or more seals (20, 21), the valve stem being slidable within the valve body, the one or more seals co-operating with the valve stem for regulating discharge of a fluid. The valve further comprises a sealing gasket (14) for sealing the valve to the dispensing container. The one or more seals (20, 21) is/are formed from (i) an elastomeric composition, preferably an elastomeric composition comprising an ethylene-propylene-diene terpolymer. The sealing gasket (14) is formed from (ii) an elastomeric composition comprising an isobutylene polymer or co-polymer thereof.
