Method for producing an in-mold labeled vessel with an elongated bottom projection

摘要

An in-mold labeled vessel with an elongated bottom projection and a method for producing such a vessel is disclosed, wherein a label for in-mold labeling is provided with a bottom portion and side wall portions. Notches are formed in folded portions of the label as connections between the bottom portion and the side wall portions of the label. Alternatively, the label is formed using material and of a predetermined thickness which permit breakage of the label at a particular resin temperature and an internal mold pressure. In order to form an elongated bottom projection integrally with the vessel bottom, the label is loaded into a mold and injection molding is performed, whereby the molding resin which has been injected flows out through the notches or through the broken folded portions into an elongated bottom projection-forming recess formed in the mold.
