Abstract
A bottle neck structure of a synthetic resin bottle preform with a preliminarily molded synthetic resin core member embedded therein is disclosed. The resin core member has a cylindrical body, that extends the length of the wall of a bottle neck, and a flange constituting a support ring of the bottle neck. At least one external surface of the resin core member is exposed to be in contact with a mold when a bottle preform is molded. The cylindrical body has a plurality of through-holes formed in its circumferential wall to allow bottle resin to flow through and form a contiguous external and internal layer. The preform is subsequently subjected to a biaxial blow-stretch manufacturing process resulting in a finished synthetic resin bottle with a neck of the present invention.
