    (54) Tamper-evident drum containers


    (57) The invention relates to tamper-evident drum containers.
    A first aspect of the invention provides a drum container (1) in which a plug top (7) is provided with a continuous unbroken web (12) overlying the whole of the top of the container without any apertures. A fracture zone (14) is formed therein to define a frangible portion (15) which when broken away defines a dispensing hole through the web. A closure disc (8) is rotatably mounted on the plug top by having a cylindrical depending flange portion (23) received in an annular depression in the web defined by a pair of spaced cylindrical wall portions (16,17) of the web, with an undercut portion (24) around the inner cylindrical face of the flange portion receiving and retaining an annular retention bead (19) on the innermost one of the cylindrical portions of the web.
    A second aspect of the invention provides a drum container (1) having a plug top (7) comprising a depending outer annular wall for insertion into the top of the drum container, and moulded thereon a continuous outwardly directed barb or snatch (10) which in use engages beneath an inturned roll or bead (4) around the inside of the top of the drum container.
