Abstract
An integral blow molded bottle having a neck, a thread surrounding the neck and a collar at the top of the neck. A circumferential flange is provided on the outside of the top of the collar and a support column is provided on the inside of the collar for limiting threading of a cap down on the neck. A circumferential groove is formed in the outside of the collar to prevent bottoming of the flange by a cap threaded onto the neck.
