Abstract
When a plurality of striped molded products are molded at a time, the molded products having a striped pattern and an outstanding design property are obtained by preventing part of molten resins from being unevenly distributed in an inappropriate manner when being fed into a cavity of a metal mold. A hot runner nozzle is provided with a first resin flow path and a plurality of second resin flow paths. The first flow path has a funnel section which continues with a nozzle gate at a centripetal position and which allows a first molten resin to be gathered at the centripetal position of the funnel section so as to feed the resin into the nozzle gate. The second resin flow paths have a plurality of corresponding discharge ports facing and communicating with the funnel section of the first resin flow path, each of the discharge ports being disposed around the centripetal position, so that the second molten resin different from the first molten resin is fed into the funnel section.
