摘要

#CMT# #/CMT# The inflation needle (1) has a central channel (4), which opens out in a front side opening at a free end (3) of the inflation needle and is enclosed from an annular channel. The annular channel is limited from a limiting wall of the central channel. The outlets are provided in the outer wall of the inflation needle in the vicinity of the free end of the inflation needle. #CMT# : #/CMT# An independent claim is included for an extrusion blow molding method. #CMT#USE : #/CMT# Inflation needle for extrusion blow molding device. #CMT#ADVANTAGE : #/CMT# The inflation needle has a central channel, which opens out in a front side opening at a free end of the inflation needle and is enclosed from an annular channel, where the annular channel is limited from a limiting wall of the central channel, and thus enables to provide a simple and cost-effective inflation needle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an axial sectional view of an inflation needle. 1 : Inflation needle 3 : Free end 4 : Central channel 6 : Annular channel 22 : Mold cavity.
