This invention relates to a canning jar sealer lid provided with a mechanically activated valve and a means for operating the valve manually. In one embodiment, a sectional sealer lid designed for use with screw bands and other holders is constructed in two parts containing apertures and gaskets so arranged that when they are fitted together and held to a canning jar lip by a holder, they unite to form a sealer lid and a relief valve. In use on a jar, the valve formed by the sections of this lid working conjointly will activate according to internal jar pressure applied vacuum sealing the jar or releasing said pressure, and there is a means supplied to manually open the valve externally. A modified embodiment is a single thickness canning jar sealer lid designed for use with screw bands and other holders which has a pressure relief means installed directly through the lid section. When this lid is affixed to a canning jar lip, the means will activate according to internal jar pressure to vacuum seal the jar or to release the pressure. This lid also has an external fixture provided for operating the valve manually.
