Abstract
A closure with tamper evident band for sealing containers and the like is provided. The closure has a top, a depending tubular skirt and a frangibly connected annular tamper evident band extending coextensively from the bottom of the tubular skirt. The tamper evident band has an annular band resiliently hinged to an inwardly and upwardly projecting annular flange for engaging a locking lug on a corresponding bottle neck. The annular band and annular flange define an annular undercut cavity so that, during capping, the resiliently hinged flange swings outwardly into the annular undercut cavity to facilitate passage of the flange over the bottle neck locking lug.
