ABSTRACT:
A thin-walled, wide mouth molded plastic container is provided with a tamper evident band initially molded as a straight-walled cylinder spaced outwardly of the lip of the container and connected thereto by a frangible horizontal bridge. The upper edge of the cylindrical band extends above the level of the container lip. Subsequent to molding and preferably before capping, the band is curled inward by application of a curling tool. The container lid is axially applied, the outer edge of the lid displacing the curled band outward. The resilience of the band and bridge permits outward deflection and immediate restoration of the curl to its initial position. The curl prevents removal of the lid without fracture of the bridge and removal of the tamper-evident band.
