The invention is based on the object of designing decorated hollow bodies in such a way that the decorative motif is effective. is protected. This object is achieved according to the invention in that the decoration motif is covered by means of a transparent film. The arrangement of such a film, "ensures reliable protection of the decorative motif and 'an excellent, true-to-color and clear reproduction of the same." the film is protected as effectively as / a paper label. ·, .- :.

The film can be formed from cellulose glass, for example. G-ün-. "Usually, however, they will be formed from a thermoplastic plastic that corresponds to the thermoplastic of the hollow body. This makes it possible to provide a pin decoration motif sunk into the plastic of the hollow body or, to a certain extent, melted into the same . It is part and parcel of this; Connection, when the sheet contour of the decorative motif which covers all sides and verbunden.ist cohesively with der.äusseren ^ of the surface, the hollow body, and when the decorative - _v rairionsmotiv in the surface of the hollow body from sere ;; a-. / is in bed and the. ..

The invention also offers the "possibility of decorating .. of hollow bodies on a special, the decorative motif exhibiting label zu.können zu.können by according to the invention Decorative motif is printed directly on the underside of the film. This measure has the advantage, among other things, that

■ -. A background of the decorative motif can be dispensed with can. Formally, when using a, label is the background of the motif print necessarily in a "certain" color and if hollow bodies are made of transparent plastic, e.g. PVC, "at least the one free from the imprint The area of the label can be recognized as not transparent. this will in many cases, felt to be bothersome, for example when use such hollow bodies as toilet or cosmetic bottles

Another significant advantage of this proposed invention can be seen in the fact that it makes it possible to use the first heat ¹ 'of the plastic as well as the blowing pressure' within the. "To make use of the blow molding tool for decoration" and to use it to complete decorated hollow bodies in one operation. Such a production can be practiced, for example, if, in the "mold cavity of the blow mold in question ..." -. A printed Foil blank is introduced which, when blowing a hollow body, inevitably comes into contact with its outer circumference under pressure ». . ^: ; ^; : ■.; ■ '-, - ..' .-. ". ■■. ', -.
