A chime assembly shaped to fit on the upper opening of a drum to receive a top and a closing ring. The chime assembly comprises a top chime having a lower band with a slot shaped to receive the upper opening of a drum. The top chime has a top flange and an upper annular portion having an annular groove shaped to receive a sealing ring. The top flange comprises a substantially axially-extending wall and a substantially radially extending flange positioned to be engaged by the cover. The chime assembly further comprises a bottom flange comprising an annular lower side wall, an annular radially-inwardly extending support surface, and a downwardly-projecting annular glide ring to contact a support surface and thereby elevate the drum from the ground surface. The chime assembly is preferably entirely plastic.
