A ring (10) for arranging around a valve body (21) of a fluid dispenser valve (20) that is mounted by means of a fastener capsule (50), such as a crimpable capsule, on a reservoir (1) containing fluid to be dispensed, said ring (10) being made as a single piece including at least one inner portion (100, 110) that co-operates with said valve body (21), and a radial flange (11) that forms a neck gasket that extends between the neck of the reservoir (1) and the fastener capsule (50).

Dispenser with a reservoir for storing liquid, and a discharge opening through which the liquid can be dispensed. The dispenser includes a metering device for discharging a defined liquid quantity upon actuation of the dispenser. The metering device at the entry side is connected to the reservoir and at the exit side is connected to the discharge opening. The metering device includes a pre-metering chamber which via an infeed duct is connected to the reservoir, and a main metering chamber which via an intermediate duct is connected to the pre-metering chamber, and via a discharge duct is connected to the discharge opening. The pre-metering chamber and the main metering chamber each have one repositionable wall, the respective chamber volume being variable by repositioning the wall. The walls are operatively coupled such that a volumetric enlargement of the pre-metering chamber causes a volumetric reduction of the main metering chamber.

The present device dispenses product from a pressurized container. The device has a metered valve that dispenses a predetermined fixed quantity of product upon actuation. The metered valve can be configured by the customer with a spacer to affect the amount of product continually metered.

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.

A fluid dispenser valve including a valve body extending along a longitudinal axis between a first axial end and a second axial end, the valve body containing a metering chamber; and a valve member that slides axially in the valve body between a rest position and a dispensing position, for selectively dispensing the contents of the metering chamber. The metering chamber is connected, in the valve member rest position, to a fluid reservoir, to fill the metering chamber by gravity when the valve is upsidedown with the metering chamber below the reservoir while the valve member is in the rest position, and to empty the metering chamber by gravity when the valve is upright. The valve body includes a first hole and a second hole, to fill and to empty the metering chamber, the first hole being axially offset along the longitudinal axis relative to the at second hole.
