Abstract
A plastic closure having a plastic liner disposed therein is adapted to assemble with a container and provide a side seal and a top seal between the closure and the container wall adjacent the container mouth. The closure includes a plastic cap having an annular ledge near the junction of the cap top wall and skirt. Downward linear movement of the closure relative to the bottle during assembly of the closure with the bottle irons a marginal portion of the liner adjacent the liner edge between the annular ledge of the cap and the outer rim edge of the bottle wall surrounding the bottle mouth, and a side seal between the closure and bottle wall surrounding the bottle mouth is provided thereby. A top seal between the closure and rim of the wall surrounding the bottle mouth is also effected by compressing a portion of the liner therebetween.
