The present invention provides a process and apparatus for readily and continuously producing foamed resin containers with labels by following a process sequence including the steps of supplying a sheet which bears label bodies printed in predetermined positions thereon, positioning a label body, punching the label body, and molding a foamed resin container with the label properly positioned. The invention further provides a process which allows for precise positioning of a label. Therefore, a thin and less stiff synthetic resin sheet can be employed for the label instead of a paper base. In addition,the label can be applied in a predetermined position on the foamed resin container without preliminarily rolling the label into a predetermined tubular shape.

[ We claim:] [1.] A process for producing a foamed resin container with a label provided on a circumferential surface thereof by integral molding, comprising steps of:supplying a continuous sheet which bears label bodies printed thereon to a label punching device upon positioning each of the label bodies at a punching position;cutting off the label body and then fixing the resulting label on a label reception platform having means for fixing the label beneath the punching position;moving the label reception platform bearing the label fixed thereon to supply the label to a predetermined position with respect to a dummy core mold;applying pressurized gas jet to the label to wind the label around the dummy core mold, and fixing the label around the dummy core mold by suction through vent holes formed in the dummy core mold;matching the dummy core mold bearing the label fixed thereon with a cavity mold, and then transferring and fixing the label onto an inner wall of the cavity mold in intimate contact therewith by stopping the suction from the dummy core mold or by pressurizing through the vent holes of the dummy core mold while sucking through vent holes formed in the cavity mold;separating the dummy core mold from the cavity mold which bears the label fixed on the cavity inner wall in intimate contact therewith; andlocking the cavity mold with a core mold, loading foamable resin beads therebetween, and heating the foamable resin beads for foam molding, whereby the foamed resin container is molded integrally with the label.
