The object of the innovation is a metallic packaging container with a floor-to-wall inner coating, in particular a size for pressurized liquid such as beer _; Consists of a blanket cover, a pressure-tight sheet metal base connected to it, and a lockable center opening axaf, which is also pressure-tight connected to the sheet metal sheet, the tin wall of the can has a chemically neutral coating *.

Such containers are increasingly being used as fuel dispensers for beer with a capacity of 4-51 used. Particular difficulties arise with such doses if the desired low manufacturing price with the mechanical strength at high internal pressure and with the chemical resistance of the inner protective vision should be reconciled. With normal beer cans or tin cans for other foods, the chemical protection is provided by one or more Achieved soles from a suitable varnish, but it has been shown that such a protection with the mentioned Dispensing sockets are completely inadequate because of their higher internal pressure. In addition to this inner protective layer, which apart from the mechanical strength it must absolutely be chemically neutral, but also the Bleohboden and the BIeohdeekel have special mechanical strength, because they are particularly exposed to the high internal pressure are. Attempts have already been made to do this through appropriate Siokung to achieve these parts, yet are the results not satisfactory in all cases.

To all ¹ fulfill these requirements in an optimal fashion; The innovation provides that, in a metal container of the type mentioned at the beginning, the Bleohmntel is approximately 0.32 mm thick. The inside is welded with a polymerized adhesive layer based on phenol epoxy resin and has an iron top layer made of a polyvinyl ketone chloride solution in the area of its weld seam, the Bleohboden and the BIeohdeokel made of approx. 0.5 mm thick, inside with a? polymerize adhesive layer on steel sheet coated with polyvinyl hydrocarbon ketone chloride, preferably NB steel sheet
