Abstract
An open top drum having a closed bottom, a sidewall extending upwardly from said bottom, and a chime portion for receiving a removable cover. The chime portion extends from the sidewall so as to define an open top and includes a substantially radial first chime wall, a substantially cylindrical second chime wall directed upwardly from an outer portion of the first chime wall, and an exterior circumferential rib circumscribing a lower portion of the second chime wall for added rigidity. The drum assembly may also include a cover having a peripheral chime receiving member, and a retaining ring having a first leg for engaging the cover and a second leg for engaging the first chime wall. The legs are joined by an intermediate band. The cover may include a circumferential flange that extends over a portion of the second chime wall but not over the rib. The rib fills a substantial portion of an area defined by the second leg, intermediate band, second chime wall and circumferential flange.
