A device for dispensing a fluid substance, including a container in which the fluid substance is housed, the container being coupled with a valve or a manual pump equipped with a hollow stem which is movable between at least a first position, in which the fluid substance is dispensed through a cavity thereof and a second position in which dispensing of the fluid substance through its cavity is prevented, there being a dispenser button coupled, in an essentially sealed manner, at the top of the hollow stem so that application of pressure to the button moves the hollow stem between the said second and the said first position, the button defining a delivery channel endowed with a first opening in a free surface of the device and which is equipped with a surface facing the stem cavity; the surface is conical or pyramidal, being tapered towards the stem cavity.

Fluid substance dispensing device

A device for dispensing a fluid substance includes a pressurised container associated with a dispensing valve featuring a supply conduit and a stem endowed with a cavity through which the fluid substance is dispensed, a chamber housed inside the container, and arranged so as to surround at least part of the body of the valve, the chamber delimited by a deformable wall and at least part of the body, the valve being of the three-way type, configured so that when the stem is in a first position, the cavity is isolated from the supply conduit and from the chamber, while the supply conduit is in communication with the chamber, wherein when the stem is in a second position, the cavity is in communication with the chamber, and wherein when the stem is in a third position, the cavity of the stem is in communication with at least the supply conduit.

Manual operated pump for the delivery of a fluid, equipped with a main part comprising a dispenser coupled with a hollow stem through which the fluid is dispensed, and a ring nut for fastening the pump to a container for containing fluid to be dispensed, the pump having a safety element, configured to be snap-fitted onto a cylindrical part of the dispenser through an opening therein so as to be interposed between at least one surface of the dispenser and the ring nut, thereby preventing the dispenser from moving closer to the ring nut in the event of an impact during transportation, the safety element featuring ribs parallel to the axis of the cylindrical part, and the main part of the pump comprises projections for cooperating with the ribs to limit or prevent rotation of the safety element relative to the main part.

Manual pump with safety element

A fluid container in the form of a can having a neck defining an opening, and fastened in a water-tight manner to the neck a valve element with a valve cup supporting a hollow stem movable against an elastic element between a first stable closing position and a second unstable position for delivering fluid through a cavity in the stem, the cavity communicating with the interior of the can in a dispensing position, the can being fixed to a support base of the container, the base comprising a support surface with a recess defined by a first centering surface to center the container on a valve cup of an identical container, on top of which the container may be placed, a second support surface for supporting the container on the valve cup, and a third recessed surface to house the stem of an aerosol valve of the further container.
