Hey Malai
The old glass lined ones made from 1940s - early 2000s would keep drinks hot or cold for up to 48 hours. Thermos even used to make it printed guaranty on their bottles in the 1960s and 1970s
If you find the old ones, them are the ones to buy. I buy them at second hand stores all the time for only a few dollars. From pint size all the way up to the big gallon size ones.
They even come total apart for super easy cleaning, unlike todays stuff
Here what they looked like in the 1980s, but if want something that keeps your stuff hot or cold for a long time. Buy the old ones
