Abstract: An elongated stiff tubular body of preferably heat-insulating material, such as cardboard, has a flexible plastic cover which is held in place at its upper end between a pair of discs interconnected by fasteners. The upper disc forms the base of a cushion of flexible padding within a flexible plastic cover. The plastic cover of the body is reversely bent around the lower end thereof and is clamped within the interior thereof by a tubular clamping member which also holds in place the upwardly-bent peripheral portion of a flexible closure of sheet material equipped with an arcuate opening closed by a circular slide fastener. A grooved base ring encircles the lower end of the body and its cover. Also held in place between the lower disc at the top of the body and the tubular clamping member at its lower end is a hollow cylindrical coating or wall of heat-insulating material, such as foam plastic. A carrying strap is secured to the body near its opposite ends for placing over the usual shoulder.
