ABSTRACT:
A novel connection for a thermoplastic neck to a stub neck portion of a container, comprising a curl on the stub neck portion and a complimentary groove on the neck which cooperate to permit a portion of the neck below the curl to expand when a plug of the closure cap, which is threaded onto the neck, is inserted into the neck. The neck and neck portion have interlocking projections to prevent the neck from turning and the neck and cap having a novel thread arrangement which insures that the plug will properly enter into the neck and provide a good seal which could be frustrated if the neck was permitted to turn.
