Description

BACKGROUND OF THE INVENTION

The present invention relates generally to insulated serving bowl, and, more particularly, relates to an insulated serving bowl that allows for easy transportation and emptying of the insulated serving bowl.

It is often desirable to cool foods prior to consumption or to keep the foods cool while serving them. Commonly, foods are cooled or chilled by refrigerating the container holding the foods. Although electric refrigerators are found in the kitchens of most homes, when entertaining it may be more convenient to have a means of chilling the foods at the location of the guests. Often this location is a recreation room or another room away from the kitchen.

Portable coolers may be filled with ice cubes to chill foods. However, it may be difficult to properly distribute and access the foods when they are to be served. If the foods are left out without being chilled they become inedible because the foods get to warm and bacteria begins to grow. This is important both for the safety of the people consuming the foods but also so that foods are not wasted.

Current serving bowls may have the ability to insulate the food in ice or a cold substance. But once the ice melts it is difficult to remove the water that has filled the bowl, the melted ice may contaminate the food, or if the substance is incorporated into the bowl the entire bowl and its contents have to be put in a refrigerator to rechill the bowl.

Thus, it is desired to have a serving bowl that is insulated with an easy way to remove the melted ice from the bowl, as well as an insulated bowl that may be easily transported.
