Method of manufacturing labeled objects. method of manufacturing labelled containers utilizing said method, and labeling preformer apparatus for use in carrying out the method.

摘要

The invention relates to a method of manufacturing a synthetic resin molded article, such as a container having a label affixed to the outer periphery thereof, and an apparatus for use in carrying out the method. Hitherto, it has not been easy to mold a container and simultaneously affix a label to its outer periphery integrally therewith and often it has been practically impossible to accurately and neatly such operation depending upon the shape and position of the label. The invention is intended to solve the foregoing problems with the prior art by preforming a label inserted in a molding die to the desired size and shape by using heat shrinking means and not by mechanically bending the label or otherwise for being shaped to the size and configuration conforming to the interior of the die. The label is of a heat shrinkable material and is preformed so as to conform to the inner configuration of the molding die and to serve for the reinforcement of the container. A labelling preformer apparatus comprising a preformer die and a lebel heating device is employed for this purpose. Label preforming and labeled container manufacturing may be carried out continuously by employing a conveyor.
