The Patent: William Stanley Jr.'s submission for a "heat insulated receptacle," patented on September 2, 1913.
Before the insulated cup and threaded stopper were introduced in 1968, the thermos was topped with a cork and a simple tin cup.
Maybe you don't keep your coffee in a thermos, but your dad probably did. So did his father. They'd tell you coffee just tastes better when poured, steaming hot, into that thermos cap cup. And they both likely owned a Stanley, which has been keeping hot liquids piping (and cold brews chilled) for 100 years. William Stanley Jr. invented his all-steel vacuum bottle in Massachusetts in 1913. The insulated bottle was used by B-17 pilots during World War II, deep sea crews and doctors ferrying temperature-delicate medicine before becoming a favorite among workmen and outdoorsmen. To celebrate the bottle's centennial anniversary, the company has introduced this limited edition re-issue that promises to keep the contents hot for 24 hours. It comes with all the features of the original like double-wall construction and a rust-proof vintage Hammertone finish, while the interior has been modernized with BPA-free 18/8 stainless steel. There's no denying that a trusty thermos comes in handy once the mercury starts dipping—whether you're commuting, camping or tailgating. Why not get one that'd make Grandpa proud?
