Food Thermos

Thermos: hotter, cooler, fresher thinking since 1904. Thermos creates insulated food and beverage containers, bottles, mugs, cups, jars, hard and soft coolers, and lunch kits. Thermos products preserve flavor, freshness and keep food and drinks safe.

A vacuum flask (also known as a Dewar flask, Dewar bottle or Thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck.

Most people have or are familiar with the "Thermos" (also known as a vacuum flask or a dewar). I can remember as a kid having one that came with my lunch box. One day my mother might put grape juice in it and at lunch I would have nice, cold grape juice.
