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.

In another review, one minus point is listed despite the five stars. Namely that the lunchbox is made in China. Apart from the fact that most items nowadays are labelled "Made in China", this is no coincidence in the case of Sigg: in 2016, the traditional Swiss company was taken over by a Chinese manufacturer of stainless steel vacuum flasks. At least the aluminium bottles are still manufactured at the headquarters in Frauenfeld, Sigg states in its company history.

The "good ones" in the potty
All in all, the manufacturers of thermal food containers are doing a good job according to "Kassensturz". Five products scored "good", with marks ranging from 5.0 to 5.4. In individual disciplines, they received better marks than the class leader from Sigg: the one from Thermos, for example, appears to be more odour-resistant, while those from Kambukka and Koor are more robust. Incidentally, Koor's thermal food container was the cheapest in the test at just under 13 francs.
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.
In the drop test, "Kassensturz" dropped each container three times from a height of one metre onto the floor. Only the Klean Kanteen product leaked afterwards. Too bad, because the TK Canister can certainly hold its own in other test criteria. It even received the best marks of all test containers for "filling food" and "spooning out of the container" with 5.8 in each case. So if you don't think you're completely clumsy, you may still want to take a closer look at the test loser.
