Abstract
This invention relates to an interchangeable disposable pan/cover having a continuous wall and a rim surrounding the pan/cover. The wall is preferably inclined and the rim is divided into two substantially equal first rim and second rim sections. The first rim section has a rolled-over bead formed at the outer end thereof. The end of the second rim section has a bead accommodating indent. The bead accommodating indent is sized so that when the bead of the first rim section rests in the bead accommodation indent, the lower surface of the first rim section abuts the upper surface of the second rim section. To have a pair of the interchangeable disposable pan/covers easily joined, each pan/cover has an orientation and closing flange extending upwardly from the outer end of the second rim section and extending substantially perpendicular to the base wall.
