Abstract
Modular plastic floor tiles have elongate drainage vents formed to extend from the general upper surfaces of the tiles to general lower surfaces thereof. In a two-shot injection molded embodiment, the vents are laterally spaced from locations of overmolded features, and may be disposed within channels defined by downwardly depending support ribs. In one embodiment, groups of elongate vents are disposed around respective fill points in radiant fashion, so as to minimize the impedance to polymer flow within the injection mold. The vents may be radiussed at the tile's upper surface to enhance their fluid collecting capability.
