Abstract: Container apparatus for a liquid, such as a beverage, includes a generally cylindrical container element with a circumferentially extending and axially elongated recess with an insulative sleeve disposed in the recess. The insulative sleeve helps to maintain the desired temperature of the liquid within the container. The insulative jacket is preferably made of closed cell foam and it fits into the recess and is held in place therein by shoulders which extend outwardly from the recessed wall.
