Abstract
Abstract The cover of the container, which may also serve as a plate, is attached to the peripheral lip of the receptacle and is movable between a lowered position wherein the lip is seated in a channel recess sealing the container closed and a raised position wherein the lip is engaged in a V-shaped recess defined by the cover skirt. A plurality of venting ports in the form of U-shaped channels are formed at spaced intervals in the cover skirt and vent the interior of the container to the atmosphere when the cover is in the raised position. The cover is designed so that a predetermined degree of positive internal pressure will move the cover from the lowered sealed position to the upper vented position and the container may be resealed by applying downward pressure on the cover to move the lip of the receptacle past a restricted portion of the skirt and into the channel.
