Soup Bowl The 9-1/2-ounce soup bowl has a unique lid that minimizes leaks and is ideal for holding soups, dips, or fruit cocktail. It sits at the bottom of the outer container, where vacuum insulation keeps the foods hot or cold for hours. Vacuum Insulation How does it keep food hot or cold? With Zojirushi"s renowned vacuum insulation technology, air between the two thin layers of stainless steel on the outer container is removed, creating a vacuum. Because there is no air, the temperature on the outside does not transfer into the container; keeping foods hot or cold for hours.
