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.

Abstract: A modular plastic floor tile (2301) has a body (2303) of a first polymer compound and at least one upper feature (106) overmolded onto an upper surface (2602) of the body (2303) from a second polymer compound which is injected from a gate (1902) adjacent the lower surface (2306) of the body (2303). At least one through-hole (602) communicates the gate (1902) to the upper feature (106). At least one vent hole (2402), spaced from the through-hole (602), communicates the upper feature (106) to the lower surface (2306) of the body (2303). The vent hole (2402) allows any gas in the polymer flow path to be displaced from the upper feature (106), thereby preventing or minimizing defects that can affect adhesion and appearance.
