a base comprising (i) a tubular wall defining a passageway through which an axis extends, the tubular wall having a first end defining an inlet into the passageway and a second end defining an outlet of the passageway, (ii) a lateral wall extending laterally outward from the tubular wall, and (iii) an outer wall extending upward from the lateral wall and forming a perimeter around the lateral wall, the outer wall is more elevated from the lateral wall than the second end of the tubular wall;
a spreader disposed above the tubular wall and the lateral wall of the base, the spreader comprising (i) a central portion through which the axis extends, the central portion disposed above the outlet of the passageway of the base, (ii) an outer portion surrounding the central portion, the outer portion terminating in an edge that defines a lateral perimeter of the spreader away from the axis, with the outer wall of the base surrounding the edge of the outer portion of the spreader, and (iii) a plurality of apertures through the spreader at the outer portion; and
a perforated sheet disposed between the base and the spreader, the perforated sheet comprising (i) a central portion through which the axis extends, the central portion disposed between the central portion of the spreader and the tubular wall of the base, (ii) an outer portion further away from the axis than the central portion, the outer portion disposed between the lateral wall of the base and the outer portion of the spreader, the outer portion terminating in an edge, with the outer wall of the base surrounding the edge of the outer portion of the perforated sheet, and (iii) a plurality of apertures through the perforated sheet.
