Benefits of technology

[0009]In view of this, it is a first object of the invention to disclose a method of producing metal packages allowing for improved corrosion protection.
[0010]It is a second object of the invention to disclose a method of producing metal packages that renders possible a relatively simple production.
[0011]It is a third object of the invention to disclose a metal package that has increased corrosion protection.

Problems solved by technology

It has been found that the operations for reforming the starting material that follow in the course of the production of the metal package, such as for example drawing, flanging or seaming operations, can impair the protective effect of a lacquer layer particularly.
However, it must be noted here that the internal spraying method does not allow the lacquer layer to be applied to all the component parts of the package, such as for example in the case of interior spaces in a package with areas that are difficult to access or with very small filling openings.
This high thermal loading necessarily requires more complex equipment and greater expenditure on the supply of energy and the disposal of emissions, such as for example of degasifying and evaporating matter.
Furthermore, such treatment may cause the risk of a coating, printing or lacquering of the outer side of the package being damaged.

Embodiment Construction

[0065]In FIG. 1, a metal package according to the invention in the form of a barrel is represented and denoted as a whole by 10.

[0066]Such metal packages are widely used for packaging and storing chemical or technical products or else foodstuffs, in particular beverages. Packages of such a design have found widespread use as beer barrels. In general, such beer barrels have a filling volume from approximately three to approximately twenty liters, barrels known as 5-liter party barrels having become established as a common container size. However, barrels with a filling volume from just a few liters to several hundred liters are offered primarily for wholesale demand and for chemical or technical products.

[0067]Metal packages of such a design are usually formed from thin or very thin metal sheets. Usually, very thin sheets have thicknesses of less than 0.5 millimeter, while thin sheets cover approximately the thickness range from 0.5 to 3 millimeters. Materials and semifinished produc...

Abstract

A method for producing metal packages is disclosed, comprising the steps of forming a metal package, in particular from steel or aluminum, from a sheet metal material, in particular from thin or very thin sheet or tin plate, wherein the metal package comprises a cavity having inner surfaces that are coated with a paraffin-based coating material. The coating material is preferably heated after coating to a temperature above the solidifying temperature.

Description

CROSSREFERENCES TO RELATED APPLICATIONS[0001]This application is a continuation of international patent application PCT / EP2010 / 061732, filed on Aug. 12, 2010 designating the U.S., which international patent application has been published in German language and claims priority from German patent application 10 2009 038 129.2, filed on Aug. 12, 2009. The entire contents of these applications are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The invention relates to a method for producing metal packages from metal sheets with a coating and to metal packages of sheet material, in particular of thin or very thin sheet or tin plate, for receiving in an interior space a product with which they are filled.[0003]Such metal packages are known in principle in the prior art and are sold by the applicant in various forms including those of flat-top drums, canisters, seamed-lid cans, hobbocks and barrels.[0004]Such metal packages are used for packaging and storing chemical / tec...
