Container having expandable neck |
摘要 |
A container is disclosed having an outwardly protruding bulge in its neck that expands in response to an increase in internal container pressure, thereby partially relieving the internal pressure increase, which benefits the label appearance and adherence characteristics, and enables the base to be reduced in weight.
