PLASTIC TUBE PRODUCED BY BLOW MOLDING

摘要

A plastic tube produced by blow molding has a main section with an essentially constant cross-section over its length, which is formed by an even number of level wall sections. The wall sections are located opposite to each other and preferably have the same width. At the front end of the main section there is a tubular opening section with a smaller diameter than that of the main section. The rear and the main section converges to an essentially straight end edge which lies in a plane extending through the central longitudinal axis of the main section and which joins two longitudinal edges of the main section to form the end edge.
