Founded in 1904, Thermos is the world’s leading manufacturer of insulated food and beverage containers and related products like kids’ lunch kits. The secret to its success is its TherMax insulation technology, which keeps beverages hot (or cool) longer by forming a vacuum space between two stainless-steel walls. The result is a lightweight product that’s cool to the touch. And the range of designs is colorful and wide, from a Barbie print to a pink-ribbon motif that supports breast-cancer research.
