<p>The technical field of the invention is that of deep-drawn plastic packages, in particular rectangular cups whose outer face carries an image or a visual decoration. The invention relates to the plastic container provided with a decorative label, to a process for applying a label without glue on a non-printed container, and to a device for carrying out the process or for producing the disclosed package. The object of the invention is to develop a fast process which applies better quality decorations or identifying signs on the plastic packages without substantially increasing costs. For that purpose, the plastic package is provided with a detachable decorative label. The label (20) is linearly applied on the wall (11) of the plastic container (10) by ultrasound-produced welding points (21a, 21b, 21c,... in short: 21) close to its edges and the welding points (21) have a much smaller surface than the label (20).</p> |
