发明名称 DEVICE FOR PRODUCING EXTRUSION BLOW-MOLDED CONTAINERS WITH AT LEAST TWO CHAMBERS
摘要 <p>A device produces containers having an inner space divided into separate container chambers by at least one separating wall. An extruder extrudes a tube of a plasticized synthetic material from an annular gap between an outer nozzle ring and an inner nozzle core. The nozzle core is provided with a guide for synthetic material that is branched off from the annular gap. At at least one outlet port at one nozzle end, the branched-off synthetic material is issued and forms a continuous separating wall that extends within the extruded tube. The guide for the branched-off synthetic material is positioned in a zone of the annular gap located upstream of and at a distance form the outlet end of the outlet port.</p>
