A multi-function cover is composed of a lid, a seat, and a fixture ring. The lid is pivotally attached to the seat at one end and has a circular groove at inner end for seating on a circular protuberance on the seat when the lid is closed. A cutter is formed at the inside of the seat and extends downward. A plurality of posts are formed at a bottom portion of the seat for insertion into holes on the fixture ring for connecting purposes. A circular groove is formed in the fixture ring for grasping the leading edge of a cap firmly.
