The rice is hot: "Kassensturz" tests thermal food containers

Have you ever wondered how long your thermal food container will keep your lunch warm? Kassensturz" investigated this question and put several containers through their paces. You can find the test winner and almost all the other products here.
Do you like to prepare your lunch even though you don't have a microwave in the office to heat it up? Then you probably rely on food containers that keep your meal warm. A "Kassensturz" test has now shed light on how well they do this. The SRF consumer magazine had eight thermal food containers tested for their insulating function. The other test criteria: Robustness, handling, odour resistance and leak-tightness.
The test sigger
A thermal food container comes out on top in the test: the Gemstone Food Jar from Sigg was the only one to receive an overall rating of "very good" with a score of 5.6.
Sigg seems to have successfully applied its decades of experience in the production of high-quality drinking bottles to its thermal lunch boxes. In any case, the Gemstone Food Jar is also very well received in our Community.
The "good ones" in the potty
Literally failed
The Klean Kanteen TK Canister was the only product tested to receive an overall score of 3.9, which was just short of "unsatisfactory". The decisive factor was the lack of robustness, which is why "Kassensturz" deducted half a mark. Without this deduction, it would still have been enough for a "sufficient" score.
