Title
(EN) Process and apparatus for manufacturing a foamed resin container with a label
Abstract
(EN)

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.
