A container with closure, in which the container has an annular tapered ridge disposed below its upper edge, and the closure has an inverted U-shaped groove with side walls sized and shaped to sealingly contact the container body at 4 surfaces. The U-shaped groove is sized slightly smaller than the portion of the container body received therein and includes a wedging portion whereby the groove walls clamp the container body side wall and is driven into tight abutment with the side wall by the wedging forces. The result is a vapor lock closure which is tightly secured to the container.
