<p>INDUSTRIAL DRUMS CONFIGURED FOR MECHANIZED AND MANUAL HANDLING An industrial drum molded of synthetic resin material, preferably by rotational molding, having a configuration including body portions provided for facilitating handling of the drum both manually and by the use of conventional mechanized material handling devices, the configuration of these body portions, as well as further portions at the bottom of the drum, also serving as a reinforcing structure for strengthening the drum. Specific surface finished are provided on different surface areas of the drum for enabling ease of labelling, handling and storage of the drum. A bung opening for a conventional threaded closure is provided by a threaded insert of a synthetic resin material having greater toughness and a higher melting point than the material of the drum so that the threaded insert can be molded in place during fabrication of the drum.</p> |
