A sidewall extends vertically from the outer edge of the base, the sidewall having an oblong frusto conical shape. The sidewall includes a bottom rim having a smaller diameter than a top rim. The bottom rim is attached to the base and the top rim forms an opening leading into a receptacle of the liner.
