ABSTRACT:
A closure that can be threadingly screwed onto an associated container includes a body having a thread form for engaging a thread form on the container. The body has a wall with projecting hook-like ribs. By the provision of the hook-like ribs, the closure exhibits an enhanced capability for being gripped by the rollers of an automatic capping machine, to accommodate a relatively high torque installation without slipping in an automatic capping machine.
