Abstract
A tubular preform for a blow molded container. The preform has a closed end and an opposite open end, the relative dimensions of the ends being such that the closed end would be receivable in the open end of a similar preform to nest there were it not for the provision of an antinesting feature in the form of at least one radially outwardly extending protrusion on the outer surface of the closed end of the preform to prevent the entry of the closed end into the open end of the adjacent preform.
