According to a first aspect of the disclosure, a spray device is provided for generating an aerosol. The spray device comprises a reservoir for containing a store of a liquid; a delivery chamber for containing a dose of the liquid received from the reservoir prior to ejection; a perforate element comprising one or more nozzles; a drive mechanism configured to drive liquid from the delivery chamber through the one or more nozzles; and a fluid metering system. The fluid metering system comprises an actuated valve that is actuatable between a closed position and an open position. The opening and closing of the actuated valve can be sequenced to control the flow of fluid from the reservoir to the delivery chamber.

Pump for dispensing a fluid product, having a piston having a pump chamber and an inlet and outlet valve. The outlet valve has an outlet valve element that slides inside the pump chamber. The pump chamber has a passage so that, at the end of actuation, the outlet valve element collaborates non-sealingly with the passage to open the outlet valve to expel product. The inlet valve has an inlet valve element sliding in a sleeve containing a spring pressing against the inlet valve element and against an end wall of the sleeve. The outlet valve element is formed by a component inserted with the ability to move into the piston, with the interposition of a second spring, the force exerted by the second spring is greater than the force exerted by the spring in the rest position, and less than the force exerted by the spring in the actuated position.

A thread dosing feeder for extracting creams or gelatinous products contained within a tube from the tube whereby the dosing feeder tube can be applied to the tube, the thread dosing feeder comprises a rotary gate feeder (1), the rotary gate feeder (1) has a metering chamber, the metering chamber operates in conjunction with a plunger (3), the rotary gate feeder (1) is pivot-mounted on the thread dosing feeder and the thread dosing feeder has an outlet, and the thread dosing feeder has a re-circulation valve (11, 14, 20), the rotary gate feeder (1) has a concave finger receptor and is formed in one piece, whereby the metering chamber is locked and has an intake and discharge valve (6).

Dispenser for the discharge of pharmaceutical media having a liquid storage, a base body, an actuating handle that is manually displaced with respect to the base body for causing a discharge process of media from the liquid storage into an environment, and an electronic detection system for detecting discharge processes. A sensor is provided, which, subject to the displacement of a reference component mechanically coupled to the actuating handle such that during a discharge process the reference component is displaced with respect to the base body, generates an output signal. The sensor is configured for generating output signals of two distinguishable types as a function of the extent of the displacement, and is provided with an electronic calibration memory in which calibration data regarding discharge behavior of the dispenser are stored.

A fluid substance dispensing device includes an external container with a containment element formed of a deformable part and an essentially rigid neck featuring a first flange which abuts with a free end of the external container at one of the mouth thereof, an intermediate element with a cup-shaped part inserted into the neck and fastened to the external container so that the first flange is sandwiched between the free end and the intermediate element, the cup-shaped part including an opening in communication with an internal part of the deformable part, there beinginside the cup-shaped parta valve element configured for displacement by the body of an airless pump so that, when the body of the pump is absent or in an unused position, the valve element is stably closed, while when the pump body is pushed into a use position, the valve element is stably open.
