Abstract
A plastic drum assembly includes a plastic body with an open top, terminated in a neck having two annular flexing zones, a plastic cover, and a ring for securing the cover to the body. The cover may also have flexing regions corresponding to the flexing regions on the neck. The flexing regions cooperate to permit the neck and the cover to flex in a hinging action in presence of an impact on the body to insure that the cover is not separated, thereby preventing spillage.
