Abstract
A lightweight metal protective closure for covering the threaded dispensing openings in steel shipping drums during the drum exterior painting process. The closure is formed as a shallow cup having a bottom wall surrounded by an upstanding sidewall. The sidewall is formed with a single embossed thread and terminates in a circumferentially extending radially fluted lip. The lip is contoured to closely overlie and protect the exposed top surfaces of the upstanding opening neck from deleterious paint coverage leaving the lower neck surfaces exposed.
