Abstract
A lid assembly includes a lid element having an annularly shaped peripheral portion configured to be axially aligned with and disposed between a rim of a canning container and a radially extending portion of a retainer element when the lid assembly is engaging the canning container and the retainer element is removably coupled to the canning container. An annularly shaped sealing element is disposed on the peripheral portion of the lid element and is configured to directly engage the rim of the canning container when the lid assembly is contacting the canning container. 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.
