5 Important Tips to Choose Thermos Bottle Thermos bottles are very useful appliances that can not only keep the stored beverage hot but also retain the chillness of cool drinks. Whether you enjoy having a refreshing chilled drink when you are outdoors or an extra cup of hot coffee or tea at the office, this kind of flasks are your best bet. However, if you are out in the market to buy your first thermos bottle​, you are likely to feel daunted looking at the numerous options you see in the range of cooking appliances. The tips given below can help narrow down your search and finally make the best choice.
Recommended Material If you are looking for a highly durable and tough product, a thermos made of stainless-steel body should be your go-to choice. Furthermore, it is very safe to use when compared to glass-based thermos bottles. Stainless steel is not only tough and durable but also non-toxic, corrosion-resistant, non-absorbent and stable. It’s suitable for storing both cold and hot drinks. This material also gives a stable vacuum insulation barrier to retain the temperature of stored liquids. Focus on the Lid Principle
When you want to buy something for portability, it must not create a mess in your backpack. A conventional lid that has a latch is prone to spillage in your bag when you carry it. Pick for a thermos bottle that has a leak-resistant cap to ensure that the stored liquid doesn’t spill around.
Vacuum Insulation Look for a thermos bottle with double-wall vacuum insulation. The principle of vacuum insulation is that it prevents the transfer of heat from the bottle’s external environment to the inside by forming a vacuum in the inner wall. Since vacuum lacks the presence of air, there’s no chance of convection and the liquid’s temperature remains stable. This makes sure that the temperature of the stored liquid is retained. The presence of double-wall does not allow the external temperature to affect the liquid that is stored within. Sweat-Proof and Heat-Proof Outer Body The thermos bottle should not allow the temperature of the stored liquid to affect its outer body. If it is sweat-proof and heat-proof, this problem gets resolved. Even if you have stored steaming hot coffee or tea, you will never feel the heat while holding the
bottle in your hand. Similarly, if you have stored chilled drinks, there won’t be condensed water drops on the outer body of the thermos. Storage Capacity When you are shortlisting your options for a vacuum flask, consider the storage volume as per your needs. Do you need just an extra serving of tea or coffee? Do you need several servings? Do you share your drinks with co-workers or friends? If you just need an extra cup during your tea break, go for a small thermos bottle. If you love to share drinks or if you travel long distances, you should buy a thermos with at least 700ml storage capacity. By following these tips, the process of choosing the best thermos becomes a lot easier. On an ending note, make sure that you buy a thermos bottle from a reputed brand that offers a warranty.
