A vented container comprising an open-topped container and a lid applied to the open top of the container, the lid being sealed to the container wall at a circumferential zone except that at at least one localized portion of said circumferential zone the lid is spaced from the container wall to permit vapor to pass upwardly through said circumferential zone, the lid above said circumferential zone cooperating with the container wall to confine liquid but having vent means for venting to the outside vapor which has passed upwardly through said circumferential zone. The lid is preferably shaped to lie in contact with the container wall throughout a lower circumferential zone and an upper circumferential zone providing a vapor receiving annulus between said zones, except that at at least one localized portion of the lower circumferential zone the lid is spaced from the container wall to permit vapor to pass upwardly through the lower circumferential zone into the vapor receiving annulus, and vent means are provided for venting to the outside vapor from the vapor receiving annulus. Desirably the lid lies in normal contact with the container wall throughout the upper circumferential zone but is distendable to permit vapor from the vapor receiving annulus to pass upwardly through the upper circumferential zone. The lid preferably has a vent hole to the outside above the upper circumferential zone.
