    Abstract: An outer closure member having a top panel and depending skirt portion. An inner closure member composed of a different material having an annular vertical wall disposed within the outer closure member and a radially outwardly directed flange integrally formed with the lower marginal edge of the annular vertical wall. An upstanding wall segment on the flange cooperating the flange and the annular vertical wall to define an upwardly open channel. The marginal end of the outer member skirt portion resiliently retained within the channel to prevent accidental relative separation of the outer and inner members but permitting intentional mechanical separation. The outer closure member may be a metal closure having an integral opening device and the inner closure member may be a molded resilient plastic material and adapted to serve both as a gasket and reclosure.
