A dispensing closure (10) for dispensing a flowable product (12) from a squeeze-type product container (14) includes a closure body (16) having an upper deck (32), an exit orifice (34), a flow conduit (36) providing a flow path to the exit orifice, and a skirt (40) configured to attach to the product container. A measuring reservoir (26) is received in engagement with a lower surface of the upper deck. The measuring reservoir is filled with a measured dose of flowable product through flow ports (54) when the container is inverted. A piston valve (28) is slidably movable within the measuring reservoir between an open position and a closed position. The piston valve is movable from the open position to the closed position to dispense the measured dose of product responsive to pressure within the container induced by squeezing.

Dispensing device for a fluid and method for dispensing fluid from dispensing device. Dispensing device includes a fluid channel; a chamber arrangement including at least one sealing element; a dispensing opening; a valve element configured to be movably disposed within the chamber arrangement and to interact with the dispensing opening; and at least one sealing element, arranged within the chamber arrangement, that is configured to create a seal against the valve element during a first predetermined stroke of the valve element.

Dispenser with a liquid storage unit, a dispensing head with a perforated plate component which has at least 25 dispensing openings in a dispensing opening region, with a pre-chamber connected upstream of the dispensing openings of the perforated plate component and from which the dispensing openings are supplied, and a connecting channel which connects the liquid storage unit to the pre-chamber. The perforated plate component is fastened on the dispensing head in an edge region and the dispensing opening region is pressed into a curved form by means of a curvature body which is arranged in the pre-chamber and acts with force upon the perforated plate.

A spray head for a fluid dispenser device, having a body with an expulsion channel terminated by a dispenser orifice, an insert in the expulsion channel, the end of the insert is co-operates with the downstream end portion of the expulsion channel to define a spray profile. The insert includes an elastically-deformable portion adapted to deform to absorb and/or compensate for variations in the dimensions of the body and/or insert, and/or to compensate for deformations and/or movements of the insert. The elastically-deformable portion of the insert has tabs that are axially and/or radially deformable, and/or an overmolded portion made of deformable material, and/or one or more radial openings that pass through the insert, and/or at least one sloping strip of deformable material.

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 trigger-type liquid ejector which includes an ejector main body and a nozzle member in which an ejection hole is formed, the ejector main body including a vertical supply tubular pipe, an injection tubular portion, and a trigger mechanism, the nozzle member including a nozzle main body and a valve body, the nozzle main body including a valve seat portion having a valve seat plate, an inside of the valve seat plate communicating with the ejection hole, the nozzle main body including a tubular foam-forming portion positioned in a front of the ejection hole and configured to surround the ejection hole, and the foam-forming portion is provided with an outside air introduction hole penetrating through the foam-forming portion in a radial direction thereof.

A nozzle arrangement that produces an atomised spray or foam wherein the nozzle arrangement comprises a nozzle body with an inlet for a pressurized fluid into a chamber with an outlet orifice in the downstream wall and a prodder with a tapered conical tip wherein the prodder is inside of said chamber and at least part of the tip of the prodder protrudes inside the outlet orifice creating at least one circumferential gap between the prodder tip and the outlet orifice whereby the fluid spins around at least part of the prodder tip and out through the circumferential gap and produces an atomized spray or foam with a substantially full cone shape.

A nozzle arrangement connected to a source of pressurized fluid mat produces a series of fast pulsed discharges of fluid in quick succession wherein the nozzle arrangement comprises a nozzle body with an inlet for the pressurized fluid into a chamber with a downstream wall with an outlet hole in said chamber wall wherein a prodder moves between a sealed and unsealed position in said outlet hole of the chamber wall and wherein a sprung plunger that is upstream of and connected to said prodder and has a annular seal that forms a seal between said plunger and the chamber creating a mobile chamber wall upstream of the downstream wall in said chamber, simultaneously moves between a downstream and an upstream position as the chamber fills with the fluid and then returns to a downstream position as the prodder returns from an unsealed position to a sealed position while the fluid is discharged.

A trigger dispenser device (1) envisages a secondary liquid aspiration duct (50) in communication with the dispenser duct, and a primary liquid aspiration duct (8) in communication with the container, off-axis with each other. Between these, a joining compartment (64) is provided communicating upstream with the primary liquid aspiration duct (8) and communicating downstream with the secondary liquid aspiration duct (50) to form the fluidic connection between them. In particular, the container (C) is of the type with built-in suction pipe.
