<p>PROBLEM TO BE SOLVED: To provide a new multi-layer thin wall container which is an integrally blow formed container of a highly flexible body part and a highly rigid mouth/ neck part and which is suitable as a container for medical transfusion, food or drink. SOLUTION: This contain is an integrally formed container blow formed, having a body part 4 and a mouth/neck part 2 for mounting a cap, by parison delivery as a multi layer structured thin wall container including a high rigid outer layer A and a low rigid resin inner layer B. The rigidity of the mouth/ neck part 2 of this multi layer thin wall container 1 is set higher than the of the body part 4 by increasing the delivery of the high rigid resin for the part corresponding the mouth/neck part 2 more than that of the low rigid resin by a parison thickness control system in parison delivery forming.</p> |
