ABSTRACT:
A closure collar member having a circular groove formed therein is attached to the tubular neck portion of a plastic container by first inserting the neck into and partially through a tubular mandril member so that the end portion of the neck will extend out the end of the mandril. The neck is then folded over the edge of the mandril and the collar member is then positioned on the mandril so that the folded edge portion of the neck will become fully inserted into the circular groove formed in the collar member. The folded edge of the neck is then fused to the collar member at the root of the circular groove to complete the seal between the parts.
