The thermos flask is also named insulated water bottle which is made by double walls of stainless steel with vacuum insulation properities, its vacuum insulation layer can stop temperature conduction from outside to inside and inside to outside, that’s why cold water stay cold for 12 hours up or 24 hours up inside the thermos bottle, you can refer to article “what does insulated water bottle mean”
As your understanding, the function of temperature retention for a thermos flask is rely on its vacuum insulation properities, the only reason why your stainless steel thermos flask stop working is its vacuum insulation properities was damage for some reasons, now we can look at how its vacuum insulation was damage.
1. A sound suspect when shake your faulty thermos flask
Sometimes, your thermos flask looks perfect without any damage, but its cold retention not working anymore to keep your water cold, why it stop working?
Now you shake your thermos bottle then you can hear a sound suspect, there is a “getter” which maintain vacuum insulation now is come off inside the vacuum insulated bottle, it will cause vacuum insulation become poor slowly until disappear then you insulated bottle not keep water cold one day.
It’s quality defect of manufacturing that you can require a refund or replacement from the stainless steel flask manufacturer or shop where your bought it.
The one answer on www.quora.com is there’s sound suspect when vacuum insulation was failure inside the double walls of the stainless steel bottle, it is one of the reason why vacuum insulation failure of the bottle to stop working to keep hot or cold.
There’s a getter welding to maintain the vacuum insulation of the stainless steel bottle constantly inside of the bottle bottom which is invisible, if the welding is poor during the manufacturing process of the stainless steel bottle then the getter will come off and you can hear a sound suspect when shaking your bottle, it means your bottle will stop working to keeps cold whatever.

For most of stainless steel insulated water bottles that stop working, you can find there’s a big dent on the metal bottle base or bottle body, which caused the two walls of stainless steel contact together and vacuum insulation layer not existing, so it won’t keep your water hot or cold for a long time anymore.
Note: a small dent won’t damage vacuum insulation properities of thermos bottle due to there’s a 4mm more space between the double walls of steel in most of bottles.
