A high flow valve for use in conjunction with a compressed gas, an aerosol or in bag-on-valve applications, and particularly to a valve having a housing that is supported by a mounting cup for a product container or can, and communicates with a product or product containment bag inside the can. A radial opening or orifice of the valve is positioned closer to a lower seal of the valve stem, rather than an upper seal or mounting cup gasket, to facilitate an increased flow rate for dispensing the product from the container and the valve.

An apparatus for dispensing a metered dose of a product, and a method for using the apparatus. The dispensing device has a charging configuration in which an outlet (112; 212) is closed and a metering chamber (120; 220) is configured to expand to its expanded configuration while receiving product through an inlet (111; 211). It also has a discharging configuration in which the outlet (112; 212) is open and the metering chamber (120; 220) is configured to contract to its contracted configuration while expelling the received product through the outlet (112; 212), thereby dispensing a metered dose of product. The dispensing device further comprises a latch mechanism (140; 240), configured to retain the dispensing device in the charging configuration until the metering chamber (120; 220) attains its expanded configuration. The method comprises actuating an actuator (130; 230) of the dispensing device, to fill the metering chamber, and releasing the actuator to dispense the metered dose of product

An inhaler (10) for the inhalation of inhalable substances comprise: a canister (50) having an interior reservoir (84) containing pressurised inhalable substances including fluid; a metering valve (52) including a metering chamber (82) and a valve stem (54) defining a communication path between the metering chamber and the interior reservoir, the communication path (86) including an opening (106) configured to permit flow between a transfer space inside the valve stem and the interior reservoir, the interior reservoir being arranged for orientation above the metering chamber whereby gas such as air located within the metering chamber is replaced with liquid from the interior reservoir.

A nasal fluid dispenser assembly (100) having a first reservoir (110) of fluid, a metering pump (120) mounted on the first reservoir (110) and including a piston (121); a compressed gas flow generator system; a nasal endpiece (150) having a connection portion (151) fastened to the outlets of the pump and valve (140), a fluid chamber (153) that receives the dose of fluid and the flow of compressed gas, and a nasal insertion element (152 that extends longitudinally along an axis (B) and contains a dispenser channel (154) connected to the fluid chamber and has a dispenser orifice (155). The axis (B) forms an angle () relative to the longitudinal axis (A). The dose of fluid is dispensed into the fluid chamber and then expelled under pressure by the flow of compressed gas out from the fluid chamber through the dispenser channel (154) the dispenser orifice (155).

Device having a vessel containing a fluid product dose, a compressed gas vessel for dispensing a dose of compressed gas to expel the dose of fluid product, and an intermediate portion having a body and a connection for connecting the vessel to the compressed gas vessel, and an actuating mechanism. The connection has first and second support members and a deformable tube attached thereto. The first support member has a first opening mechanism for opening the vessel and the second support member has a second opening mechanism for opening the compressed gas vessel. A spring is between the first and second support members, the actuating mechanism has a button rigidly connected to a cage which locks the support members axially. When the button is moved radially, the support members are unlocked and the spring moves the two support members towards their actuating positions.
