Dosing body with an external base covering, method and device for applying the base covering

Abstract

A can body with a jacket-like closed wall and a base constructed on one end of the can wall includes an external base covering in the form of a sheet material. The base covering is fixed into position on an annular connection region of the can body. The base covering can form a basically flat imprintable region in a main region that is surrounded by the connection region. If a bar code can be applied in this imprintable region, then a restriction of the configuration possibility of the can wall disappears. The base covering can form a stand region whereby a standing can body is only in contact with the support surface if necessary via the base covering, and consequently the occurrence of corrosion problems is prevented. A retaining device that leaves the base of a held can body free and a position fixing apparatus are used for fixing the base covering into position. A decorative foil on the exterior of the can wall can be overlapped by the base covering, which serves to prevent a detachment of the decorative foil on the base.
