METHOD AND DEVICE FOR THE PRODUCTION OF PLASTIC CONTAINERS

摘要

The invention relates to a method and a device for the production of blow-molded two- or multi-layer containers made of thermoplastic, and a plastic container produced accordingly, having view strips, particularly for storage and for transport of liquid bulk material. To this end, molten plastic material is deflected in an extrusion head (10) from the inner, natural-colored layer (34) of the tubular premold (18) into the outer layer (36) in a process technical step, and embedded there, whereby a view strip (24) is formed in the exterior, dyed plastic layer (36).
