How to choose a good thermos flask(2)

Lids - You may also want to look for thermoses with lids that can also be used as a bowl so you can eat on the go, and some thermoses come with a collapsible spoon.

Materials - Thermoses can be made from a variety of materials, some of which are much better than others. Plastic is a cheaper material and will certainly reduce the cost of your flask, but a thermos - stainless steel - curved food flask is not recommended as it does not retain heat well, it is fragile and is likely to break. Metal flasks, mainly stainless steel are more recommended as they are durable, easy to clean and retain heat better. It's a good idea to check reviews of a number of different flasks to make sure they are up to scratch, as you can't tell how good a flask is just by looking at it and reading its product description.

Keeping warm - Keeping warm is another important factor, as a food jar can keep food hot or cold for anywhere from around 4-5 hours to 12-15 hours. You also need to check how long the food jar will keep your food cold. Typically, food jars are able to keep food cooler for longer than they keep it hot, but some flasks may not be tailor-made for cold food at all.

Warranty - Warranty is another important factor to consider. Some flasks/insulated food jars offer a longer warranty that may cover you for ten years or more, while others do not offer a warranty at all. If you are going to spend a lot of money on your flask, you will want to make sure that you are covered in the event of any problems.

Thermal Flask:

This type of thermal Flask is essential for coffee lovers everywhere. If you want to take your morning coffee to work, if you want to save on chain shop coffee without having to resort to instant coffee from the office, or if you are planning a long trip or hike and you want to stay warm and alert throughout the day, then a stainless steel thermos is a good choice.

It is very important that your water bottle is able to keep your drink hot/warm for as long as possible. Some thermoses will keep your drink warm for up to 24 hours, while others will only last around 6 hours or less. If you are going on a trip and you want to drink steaming hot coffee all day then you will want the thermal Flask to keep your drink warm for as long as possible, but if you only need to keep your drink warm for a few hours then this is not as important. Remember to check customer reviews as sometimes a product will boast that it will keep you warm for longer than it really does.
