"Spray head for aerosol dispenser"

The present invention relates generally to Aeroeol - dispensers, in particular to a new kind of beasered dpritskopf "um Zaräuben des Spenderinnalta"

The aerosol containers widely used today consist of a canister or a tube which has a considerable internal pressure and contains a constant amount of spraying liquid. Such features include, for example, Inaektlcide, paints, StMrkeldsungea, KoiMtika and the like. With the "u veraprtthenden rittssigkelt" the container takes up a certain amount of a driving town, end "was usually one of the easily verflügeneen Ohlor-fluor-ethene-Gae · _f as s« B · dichlor- <3i in the trade under the Basel bill " FKKOf "known.
