Abstract
A cooling system, for cooling the contents of a utensil, utilizing a removable, reusable, refillable, freezable toroidal-shaped cooling insert and a toroidal-shaped insulator. The cooling insert and insulator stack in a nested manner within the utensil to provide improved insulating and longer cooling of the utensil contents. Furthermore, a secured bottom holder removably holds the cooling insert and insulator within the utensil. The cooling system includes the use of a temperature sensor and display which provides a visual indicator when the contents have reached a temperature indicating the contents are no longer being properly cooled. Such utensils may include, for example, dog dishes, bait containers and food containers.
