Most Important Things to Know About Thermos Bottle

Most Important Things to Know About Thermos Bottle Carrying your own bottle is the need of the hour - this way, you wouldn’t be adding more to the use-and-throw bottles that end up in landfills, thus contributing your bit to the environment. It’s also economical to carry your bottle. But, in summer and winter season, instead of a normal bottle, it makes more sense to carry a thermos bottle that keeps cold drinks cold and hot beverages hot due to insulation. Thus, if you want to carry cold water, chilled juice, cold coffee etc. during the summer months, it will stay cold for a few hours. Similarly, carrying tea, coffee, soup etc. will remain steaming hot for you to sip even after a few hours.

Though the thermos bottle does not exactly fall under cooking appliances, still like any other cooking appliances, care is taken in its designing to make life comfortable and convenient for its users. Here are a few important things that you should know about thermos bottles.

Lid of the Bottle As you will be carrying around the thermos ​bottle you buy, it should have a leak-proof lid. In the absence of it, you won’t be able to put it in your gym bags, office bags, handbags etc. The purpose of this bottle is to have chilled juices, smoothies or hot tea, coffee during the break or after a work-out. If the lid is not leakproof, this purpose will not be met.

Material Quality

The material of the bottle plays an important role in preventing the transfer of heat or cold through it. It should be of good insulating quality so that no such transfer happens either by convection or conduction. If you buy an inferior quality material, the liquid stored in it will not retain its hotness or coldness and the bottle will be a complete failure.

Thickness of the Inner and Outer Walls of the Bottle Thermos flasks have a double wall vacuum insulation. The purpose of this double-wall insulation is to keep the bottle sweat-proof from outside so that it can be placed safely in the bag. The vacuum between these two walls prevents the heat transfer between the liquid stored in it and the outside environment. If the thickness of this vacuum is not enough, the heat will get transferred by either conduction or convection and the beverage stored will lose its hotness or coldness.

Design of the Bottle As you will be carrying the bottle with you, it should be sleek, compact and light. If you buy a glass bottle, then it would be heavy and will always carry a risk of getting broken.

A plastic thermos bottle will be light, but there is always a fear of harmful chemicals getting leached into the stored fluid, especially if you are carrying something hot and the bottle is of low-grade plastic. In such a scenario, a sleek metal thermos flask is the best bet, which is a practical and durable alternative.

These are some of the important things that you should be aware of when you are buying a ​thermos bottle​. Lastly, you should buy the bottle from a reputed manufacturer so that you can be sure that it would meet all the required criteria and will keep your beverage the way it is stored for hours.
