The air vent holes are placed superiorly in a central vertical stalk. The base has one or more air channels that allow air ingress and egress from the outside atmosphere to the raised central stalk area. The central vertical vent stalk has a dome shaped roof with an overhang to channel spilled liquids away from the air vent holes onto a sloping floor which in turn diverts the liquid to the outer corners of the inner receptacle base.
