Abstract: The present invention is an improved plastic industrial container which may be used for packaging, shipping and dispersing a variety of liquids while protecting the contents from tampering and theft. The container is manufactured in components which include a pail body, a cover and a nestable pour spout closure. The improved container design facilitates press fit assembly of the cover to the pail in the usual manner, but which blocks tool insertion and undamaged removal of the cover. The invention specifically relates to an improved cover and closure combination which facilitates the press fit assembly of the closure to the cover but which resists tampering. The barrier molded with thin cross section with frangible elements to be easily damaged if tools are used in a prying manner on the closure wall resist tampering by restricting the clearance for tool insertion and closure removal.
