ABSTRACT:
A lid device for a wide-mouthed container comprises a metallic lid body having an inner margin defining an opening of a predetermined shape, and a closure member made of a soft synthetic resin for closing said opening of said lid body. The closure member is integrally formed with a pull tab used to open the closure member along a weakening line. The entire outer surface of the closure member is covered by a vapor impervious film, so that passage of water vapor through the lid device can be prevented even if the closure member itself is vapor pervious.
