Best thermos flask in India
Before I share my recommendation of India’s best thermos flask brands, let me first answer a few basic questions about the thermos flask.
What is a thermos flask?
A flask is a narrow-necked container or vessel. A thermos is a flask with insulated walls that help keep the flask’s content warmer or colder than its surroundings. It is also called a vacuum flask.
A thermos is also known as a Dewar flask or Dewar bottle because Sir James Dewar invented it in 1892.
How does a thermos flask work?
A thermos is essentially one flask contained in the other without the body touching. Both are joined only at the neck. Even the air between the two flasks is removed during manufacturing. Therefore they are also referred to as vacuum flasks. Since the inner flask is not touching the outer flask, this prevents the heat from escaping either by conduction, convection or radiation.
If you are interested in going into the detailed design, then check out the video below.
Thermos works perfectly for cold drinks too. So, enjoy your coffee just the way you like it, hot or cold!
Buyers’ Guide: What to look for when buying the best thermos flask in India for yourself
Thermos flasks can be very handy and cost-effective for storing and carrying your drinks around while maintaining them at your desired temperature. I have noticed that because of all the false advertising that thermos flask brands do, it becomes very confusing in choosing the best one for yourself.
You should first think of the purpose of why you want to purchase a thermos flask. What is your need? And once you have the answer to that question, you can start with the best thermos that matches your basic needs and gives you additional benefits.
Since all thermos flasks are not created equal, the following are the top points that you should keep in mind while buying a thermos for yourself.
The capacity of the thermos flask
A thermos comes in various sizes, from 300 ml (small) to 700 ml (large). Based on your need, you should pick your ideal capacity. Remember, higher capacity means bigger the size of the thermos. And bigger size can make it inconvenient to carry.
I have two thermoses, one small (300 ml) and another large (700 ml). I use the small one for carrying cold water or warm tea to college during summer or winter, respectively. The large one I use when I go on road trips or picnics with my friends.
Material of thermos flask
The material can considerably impact the durability and perishability of your drink and the thermos itself. Thermoses are now available in many types of materials like stainless steel, plastic, glass etc. Each type of material has its benefits.
The insulation of your thermos and the quality of the double layer can also have a significant impact on the vacuum seal. So read the material description of the product you plan to buy.
Today, Stainless steel is the best material for a thermos flask. It is durable, and resistant and also has an easy-to-clean exterior.
Thermos flask should be leakproof
I cannot stress enough the importance of having your flask leakproof. You can have disastrous consequences if your flask is not leakproof, and I am talking from experience here. Even a small leak of the liquid stored inside your thermos can cause significant pain.
Checking on a secure and effective lid is the key. The cap must be firm and able to loosen and tighten quickly and should fit the flask flawlessly. Even if you have to pay extra, always go for the best quality lid.
Lid type of thermos flask
The type of lid is also essential. There are many types of caps available in the market today, like push-button lids, dual-purpose lids etc. Try avoiding the push-button lid as it may tend to get loose over time. Also, if considering the dual-purpose lid, You must check the tightening and loosening of the cap on the thermos before the purchase.
The grip of your thermos flask
Grip in a flask is essential as it will protect you while holding a very hot or cold thermos. Handles must be placed at the convenient and ergonomically best location in a thermos. Nowadays, many thermos flasks come with a carry bag to make them even more portable.
Ease of cleaning your thermos flask
The design and material of your flask will define the ease of cleaning for you. It would be best if you always cleaned your thermos after every use. Since cleaning your thermos is essential, read the instruction on your product to find the best way to clean your thermos. While purchasing, make sure there is nothing in your flask that would make cleaning it difficult.
Temperature retention of the thermos flask
Temperature retention is the core feature of a thermos. On average, a thermos can keep liquid hot or cold for 4-5 hours to 10-12 hours. Some high-quality thermos can also retain temperatures for up to 24 hours. Read the product manual carefully to know your thermos flask’s temperature retention capabilities before buying.
Vacuum
The vacuum layer is the main feature of your thermos as it blocks heat transfer. This vacuum layer should be well-tightened, thick as well as compact. The material of the thermos does not play much of a role in the vacuum layer.
10 Best small capacity (up to 499 ml) thermos flasks in India
As I mentioned earlier, having a small (less than 499ml) capacity thermos is essential. It’s easy to carry, portable and cute.

13 Best large capacity (1 litre and above) thermos flask in India
It would be best if you were drinking approx 3 litres of water every day, and for that, you need an excellent insulated flask with a large capacity.

FAQ
Following are some of the Frequently Asked Questions (FAQ)
Difference between a thermos and a non-thermos flask?
A thermos flask has a vacuum chamber between the two insulating layers. A non-thermos doesn’t have two insulating layers or a vacuum chamber. As a result, a thermos has much better temperature retention, so it can keep liquids hot or cold for a longer duration.
Difference between Thermosteel and a vacuum flask?
A thermos and vacuum flask are the same things. Thermosteel is a brand from Milton. They refer to their stainless steel flasks as Thermosteel.
What should I not put in my thermos?
A thermos only keeps content warm until they are in liquid form. Therefore solid or saucy foods must be avoided as bacteria can grow, leading to food poisoning.
Is it better to buy a thermos with copper?
Yes, copper should be preferred. The copper metal has many health benefits—for example, it’s good for balancing hypertension, preventing anaemia, fighting cancer, and many more. As long as copper insulated vessels meet the safety production standards, copper vessels must be preferred.
Is stainless steel good?
Yes, stainless steel thermos flasks are sturdy, good for health and very economical. Stainless steel is an alloy. It is lightweight, strong and corrosion-resistant.
Are all vacuum flasks designed to retain temperatures for 24 hours?
No, the duration of temperature retention depends on the material, design and construction of the thermos. On average, you can expect your liquid to remain hot or cold for up to 6 hours in a thermos. If you want higher temperature retention, go for flasks with higher temperature retention.
Is it alright to put carbonated drinks like Coke and Pepsi in my flask bottle?
Yes, you can store fizzy drinks in your thermos. The vacuum will keep the gas from escaping and will keep your drinks cool. Just be careful of the fix when you open your flask containing carbonated drink.
Can I use a thermos water bottle for tea and coffee?
Yes, you can use it for tea and coffee. Just remember all thermos flasks will lose some heat with time. So make your tea or coffee a little extra hot before storing it in the thermos flask.
How can I remove the bad smell from my thermos flask?
Giving it a thorough rinse with warm water and pouring vinegar and baking soda will wash off any foul smell from your thermos flask.
What makes insulated bottles a better choice over glass?
Besides the advantage of keeping drinks insulated from temperature change, there is no significant difference between storing drinks in glass or insulated bottles. However, the material that holds liquid in insulated bottles must be inert and should not alter the quality of the beverage.
What does BPA-free mean?
BPA means Bisphenol-A, which is an organic synthetic compound. Exposure to BPA is harmful to the brain and prostate glands. So make sure your thermos flask is BPA-free and also toxin-free.
How can you remove stains or odours in the thermos?
Adding vinegar and baking soda along with hot water will wash off any smell or stain from the thermos. For thorough cleaning, let the mixture sit overnight and then wash off.
