Vontil'oinriohtung for pre-spraying under pressure Variable speed products

The invention relates to improvements in a valve direction for Pressure pack for dispensing pressurized products, «which allows the user to choose between several different Select the spray speeds at which the product is dispensed from the same pack

In a known detachable spray head valve device for pressurized packages, a spray head is used with a downwardly directed hollow shaft which is provided with a slot which extends fully through a side wall. The slot cooperates with einom federbolaeteten valve piston and an annular rubber seal, a passage of the pressurized product from the interior of the package on the valve piston and into Oino hollow EntsptgpQUMwkasimer An, the bore of the üohaf about teu

daa oboi-Q the end of dos Uchlitzoo to become possible Design, such a protective arrangement is also used, however, a facility was also provided »with their help dor user one of several different üprita- baw. Sprühga-Qohnindisskoiten can be achieved by rotating the spray head in a position different from Eiehreron · With one rotation the spray head works with floods on the inside of the valve piston are designed »by a different spray speed in any of several different positions to which the shaft can be rotated. In addition, there is a different maximum spray speed provided in each Such a position can be achieved »however, the user can turn the spray head slightly out, in any position and change the spraying speed. For the sake of simplicity of description assumed that three main positions or stages are provided " When the spray head is in one of the steps or positions, it can be rotated slightly without affecting the step or position leaves, but there is a change in the spray speed is · Furthermore · a · certain position doo 3sprühkopfos between the stages provided »in which there is no pressurized Product can be dispensed because there is no connection between the hollow

Stem and the interior of the pressurized pack. The user will therefore be able to see the stages more easily and there is no overlap between the stages so that an accurate spray speed can easily be assigned to each stage.
