A top cover is mounted on the top of the annular wall. The top cover includes a crown having a central hole. The crown includes a plurality of cigarette receiving grooves. The crown further includes an annular wall extending downward from an outer peripheral edge thereof. The annular wall has an inner diameter slightly larger than an outer diameter of the annular flange. A plurality of protrusions extend inward from a lower edge of the annular wall.
