A lid assembly for use with a canning container having a rim and a retainer element having a radially extending portion, the lid assembly comprising:

• a lid element including:
• a centrally disposed domed portion;
• an annular channel portion disposed radially outwardly of the domed portion;
• an annularly shaped peripheral portion disposed radially outwardly of the channel portion, the peripheral portion configured to be axially aligned with and disposed between the rim of the canning container and the radially extending portion of the retainer element when the lid assembly is engaging the canning container and the retainer element is removably coupled to the canning container;
• and
• an annularly shaped sealing element disposed on the peripheral portion of the lid element and configured to directly engage the rim of the canning container when the lid assembly is contacting the canning container, wherein a plurality of projections is formed in the peripheral portion of the lid element with each of the projections forming a distally disposed surface of the peripheral portion with respect to an exterior axial direction of the lid element extending away from an interior of the canning container when the lid assembly is engaging the rim, wherein each of the projections is configured to directly engage the radially extending portion of the retainer element when the retainer element is removably coupled to the canning container, and wherein each of a plurality of segments of the peripheral portion interposed circumferentially between adjacent ones of the projections is axially spaced apart from the radially extending portion of the retainer element when the retainer element is removably coupled to the canning container.
