A plastic lid for closing a container neck opening according to one embodiment of the present invention comprises a lid body surrounded by an annular rim, the annular rim defining a gasket channel having an open portion at one end opening toward the container neck opening and including a closed base at an opposite end. The annular rim defines a pair of raised annular beads positioned adjacent the open portion of the channel for capturing a gasket received within the gasket channel. The corresponding gasket may be either a preformed gasket that is inserted into the channel or a foamed-in-place gasket that is formed in the gasket channel. No pretreatment of the lid is required for the installed gasket to be retained in the gasket channel.
