1. A closure configured to fit over a mouth of a receptacle to form a container, the closure comprising: a skirt defining an outer periphery of the closure and having an open bottom end configured to fit over the mouth of the receptacle; an end wall positioned atop the skirt to close a top end of the skirt and form a top face of the closure; one or more openings formed through the end wall, wherein the one or more openings provide an air passage to a space between the skirt and the mouth of the receptacle; and a sealing rib formed on the top face and diametrically disposed outboard the one or more openings, wherein the sealing rib is raised from the top face such that the one or more openings are positioned below a top surface of the sealing rib, wherein the top surface of the sealing rib is substantially flat and configured to interface with a corresponding surface of a sealing device to substantially seal an air space formed at least partially by the sealing rib and the raised top surface; so that when the air space is sealed at the sealing rib, air sent into the air space is forced through the air passage provided by the one or more openings and through the space between the skirt and the mouth of the receptacle.
