Abstract
A drink container and plug lid for use therewith. The lid has an upper member and a lower member with a ring seal positioned therebetween and radially outwardly stretchable from an initial diameter to a larger sealing diameter in response to an actuator moving the upper and lower members together to place the ring seal in fluid-tight sealing engagement with the container body. Moving the upper and lower members apart allows the radially outward stretched ring seal to move from the sealing diameter to the initial diameter whereat it is out of fluid-tight sealing engagement with the container body.
