A plastic container closure has a skirt (29) which is connected to a tamper-evidencing band (33) by frangible bridges (38), all molded in a single unit. Where the closure is a cap for a container neck, there is at least one retaining means on the skirt (31) and another on the band (34). The neck has two retaining means (21, 16) which cooperate with those on the cap to prevent upward movement of the cap without fracture of the bridges (38). To reduce the likelihood of unitentional fracture of the bridges (38), particularly during installation of the cap on the neck, plural ejection bumpers (36) of extended arcuate lengths are located on the top edge of the band or from the bottom edge of the skirt and the bridges (38) are located between the bumpers. This tamper-evidencing band is applicable to closures of push/pull-type spouts or sports-type cap spouts.
