Problems solved by technology

As a result, fluid close to the discharge orifice of a nozzle is removed by the moving plug, which brings the fluid into contact with other nozzles or with droplets of a different fluid, resulting in undesired contamination in the fluid
[0005] This disadvantage is obviously counterproductive, all the more so in the field where each nozzle usually dispenses a corresponding paint dosing of colored fluid; in fact, as long as the tip of the nozzle is contaminated with traces of other colors, it consists of a mixture of different colors The final product will have a different color than desired

Embodiment Construction

[0020] specifically refer to figure 1 , Figure 7 , Figure 7a , Figure 8 , Figure 8a , the numeral 1 generally indicates the illustrative type of fluid dispenser.

[0021] According to the figures, the fluid dispenser 1 comprises a discharge opening 2 which - for the purpose of the present invention by way of non-limiting example only - is the distal end of a dispensing head provided with a plurality of holes or nozzles 3 , each hole or nozzle 3 is used to dispense a fluid having characteristics different from those of the other nozzles (in particular, said nozzles are designed to be flowed through by a different color). In the example shown, the plurality of nozzles 3 is slightly recessed relative to the distal end (discharge opening 2 ) of the peripheral axially protruding dispensing head.

[0022] Based on what is generally shown in the figures, the fluid dispenser 1 has a generally tubular shape and protrudes downwards from the bottom of a bracket or overhang 4 car...

Abstract

The device (10) comprises: a rotary portion (14), which is mounted so as to rotate on a support structure (12) around a rotation axis (X-X) between an angularly moved away condition and an angularly moved close condition relative to an outlet mouth (2); a shutter portion (16), which pivots relative to the rotary portion (14) around a pivoting axis (Y-Y) lying on a plane that is transverse relative to the rotation axis (X-X); and an actuating apparatus (18), for moving the rotary portion (14) between said moved away condition and said moved close condition. The shutter portion (16) is suited to pivot around the pivoting axis (Y-Y) from an opening position, in which the shutter portion (16) is spaced apart from the outlet mouth (2), to a closed position, in which the shutter portion (16) lies against said outlet mouth (2), when the rotary portion (14) shifts from the moved away condition to the moved close condition.

Description

technical field [0001] The present invention relates to a device for closing the outlet of a fluid dispenser, in particular a fluid dispensing head for a fluid, typically such as paint, dye, additive or chemical composition. Background technique [0002] In the field of fluid dispensing machines, when a fluid dispenser, usually provided with at least one dispensing nozzle, terminates the dispensing operation, it is known to use closing devices designed to close the discharge opening of the associated machine. In this way, it is possible to prevent the fluid near the discharge port of the nozzle from being exposed to the air, thereby making the fluid prone to deterioration. [0003] The use of shut-off devices of the above-mentioned type has spread especially in the field of paints and varnishes, where the skilled person usually uses a machine comprising a dispensing head provided with a plurality of nozzles in order to dispense fluids of different properties and / or colours, ...
