Use
Products with a plus in the name have sealing rings made of food-safe silicone and are leak-proof. For all other products, we do not use a sealing ring. This is not a problem when transported upright, but we cannot guarantee 100% leakproofness with the standard versions. You can find an variety of the leak-proof products in our webshop.
In the boxes and bottles of ECO Brotbox both cold and hot food and drinks can be transported. However, since our standard products are made of single-walled stainless steel, these products have no insulating function, i.e. they keep the contents neither cold nor warm. Attention with hot contents – these products can also become very hot outside!
If you want to keep your drinks or food cold or hot for a longer time, we recommend our insulated bottles and containers made of double-walled stainless steel.
Note: The non-insulating Tiffin Swing+, Bento Classic+, Bento Flex+ and Yogi Box products should not be filled with hot food as this will create a vacuum which will make it difficult to open the box again. Please allow the food to cool before filling.
Not all stainless steel products are allowed to be used in the microwave. You can use our Yumis and the Thali plate in the microwave. Up to 1000W and without lid!
When used in the oven or on the grill, extreme caution is required as the material becomes extremely hot and there is a risk of being burned. You can use products in the oven without lids.
The containers can basically be used for freezing. However, we do not recommend it as frequent freezing can lead to material fatigue. This shortens the lifetime of the boxes. In addition, you should take care not to fill the frozen food too high so that the frozen food can spread without stretching the container. The frozen product can cause a very high pressure and deform the box significantly.
The locking clamps of our boxes are adjusted manually during production. This means that the strength of the clamps can vary from box to box. We do check the strength of the clamps before shipping, but if a clamp still is too tight or too loose, it can be easily adjusted to your needs by slightly bending it.
Here is a short video on how to do that: How to adjust clamps
By using sealing rings your box is leak proof. However, when eating very hot food, negative pressure can form which makes it much more difficult to open the box. Please let the food cool down before closing your box. For very hot food (over 70 degrees) it is advisable to remove the sealing rings – but be aware that now the box is no longer leak-proof.
Tips for opening:
- Tiffin Swing+/ Tiffin Double+/ Tiffin Pro+: we have created a video to help you.
- Shanti Box+/Tiffin Bowl+: to release the negative pressure and to remove the separator plate, please pull the tab on the sealing ring a little.
A fine crack in your box is probably a stress crack.
These can occur in rare cases if the material gets too stressed during production. Please contact our customer service and we will immediately send you a new box.
A common reason for smaller amounts of leaking liquid is that during cleaning water has entered the inside of the lid through the handle holder – and then slowly leaks out again. The water can be removed simply by shaking the lid or by placing the lid on a cloth overnight with one of the holes in the handle holder facing downwards so that the water can exit.
In many cases, the problem can also be solved by inserting the silicone ring correctly. This is how you insert it correctly:
