Is a thermos food jar patented?

Short answer: specific designs of a thermos food jar have been patented many times, but "a thermos food jar" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What our index shows
  • 394 US and WO patent publications since 2000 have a title matching “food jar” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 41 best keyword matches we examined, 15 were published in 2020 or later, and the earliest was published in 2000.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a thermos food jar been patented?” but “has my combination of features been described before?” Kitchen gadgets are a crowded, mature field; novelty usually sits in one specific mechanism, the material, or how two familiar functions are combined.
