Abstract: A closure for sealingly closing a container neck having a tubular body with a top wall, an annular side wall, an intermediate wall joining the side wall to the top wall and an annular tamper evidence band frangibly connected to an open end described by the side wall. The band includes retaining cams protruding from its inner surface. Each cam has a lead-in ramp for engaging, in use, the flange of a container neck as the neck is introduced into the open end of the body and a stop for engaging the flange to separate the band from the body when the closure is subsequently removed from the neck. Each lead-in ramp has a central recess therein.
