Contents of a thermos flask
They come in all sorts of shapes and sizes. You can take them anywhere, making them very convenient. In our range, we have different sizes of thermos flasks, from 300 ml to as much as 1.2 L. You can go for a small thermos flask of 300 ml. This is perfect for a short walk or a small backpack. Prefer a larger capacity? Then the 750 ml and 1 L flasks are also popular sizes. These are perfect for a longer day out.
How long does a thermos flask stay at temperature?
A thermos flask can keep your drink warm for up to 12 hours. You can be out all day and still enjoy your warm tea. On warm days, you benefit greatly from it as well. Cold water stays cold for up to 24 hours, and if it gets too warm outside, you can add ice cubes to the water to cool down. The duration for which the contents remain warm or cold can vary per thermos flask, so be sure to check the product information of your favorite thermos flask for specific details.

How to clean a thermos flask?
Cleaning is not a difficult task. It's handy to check beforehand if your thermos flask is dishwasher safe. This varies by type, and often they are only suitable for hand washing. You can easily wash and rinse it with some warm water and soap. This will keep you going for a while. If you want to do a deeper clean, you can fill the thermos flask with soda water. After a night, rinse the flask, and it will be nice and clean again. This way, you can enjoy it for days.
Material of thermos flask
The stainless steel thermos flasks are rustproof, making them easy to clean and ideal for daily use. This way, your busy workweek won't be disturbed by a dirty drinking bottle. Because the thermos flasks have a double-walled system made of stainless steel, the contents stay warm or cold for a long time. The air between the two walls has been removed, creating a vacuum. This prevents heat from escaping or heat from reaching the contents. Our thermos flasks are made of stainless steel. An advantage of this is that these stainless steel flasks do not break. Some even have a silicone layer around the flask for a nice design.
What is a good thermos flask?
Everyone has different important points that make a good thermos flask. You mainly pay attention to a few points. First, it's important to consider how long the contents stay warm and cold. This is, of course, an essential point, as that is what a thermos flask is all about. The material is also important. Everything we offer is made of stainless steel, so they don't break. The Cookinglife range includes several brands, including two popular ones: Mepal and Sareva. Ultimately, it depends on you which thermos flask you find the best.
