Buying Guide – Best Thermos Flasks in India
When it comes to investing in a homeware appliance, accessories, or daily use products, we always look out for the best products. We must consider several factors before buying the actual product such as durability, longevity, value for money, material, etc.
Similarly, before buying thermos flasks/ bottles, there are a few factors that have to be kept in mind before buying the actual product.
We have gathered and listed below all the important factors to consider, so that it’s easier for you to go through them and your expectations match your reality for a particular product.
Factors to consider before buying a Thermos Flask
1. Capacity
This is one of the most important factors out of many. It is very much necessary to first identify what size of the flask you require depending on the ml of liquid you want to carry.
If you want to use it regularly for the gym, or office, then a small or a standard size would do. But if you go on treks, long drives, or picnics often, then a medium or large size would be preferable.
So, the first important step is to identify the size. Generally, thermos flasks and bottles come in various capacities and sizes such as 500ml,750 ml,1000 ml, etc.
2. Heat/Cold Retention
Thermos flasks and bottles usually have vacuum insulated double walls which help in the temperature retention ability i.e. the temperature of the liquid poured inside it lasts for around 6-24 hours be it any hot liquid or any cold liquid.
Some have the temperature retention ability for 4-6 hours and some others, more than that. So, it depends on the consumer as to which one they prefer- short hours or long hours.
3. Material
Generally, all thermos flasks or/and bottles have a stainless-steel body both on the exterior and the interior. Stainless steel is one of the cheap and yet the best choice to use in a product if it has to be made long-lasting, durable, and rust or corrosion-free.
The flasks generally have an 18/8,304 food-grade, BPA-free quality stainless steel which is one of the best.
Some flasks also have a copper coating in the inner portion over the stainless steel to prevent the contamination of the liquid and keep the water or beverage safe for drinking. The copper coating and the stainless steel both help in the temperature retention of the flask or bottle.
4. Type of insulation
Vacuum and foam are the most common types of insulations that are present in thermos flasks or bottles. The vacuum system is present in the gaps of the interior and the exterior wall of the flask and prevents the external temperatures from affecting the temperature of the liquid inside.
The presence of the vacuum technology also makes the surface condensation free and dry i.e., no accumulation of water droplets on the surface. This disables the slipping of the bottle from our hands.
The other type is the foam type. In foam technology, the convection gets disabled due to the presence of foam between the walls.
The foam stays intact and doesn’t allow air molecules to pass through it, and through this, it prevents the outer temperature differences to affect the inner temperatures. However, when compared between foams and vacuum insulation; vacuum helps retain the temperature for longer hours.
5. Leak proof
It is very important to note the fact, whether the flask is leak-proof or not. The lid is leak proof or not is the next important factor. The lid should fit correctly and precisely on the mouth/opening of the bottle thus allowing no drips or leaks.
In some flasks or bottles, the surface is also made leak proof. This feature, however, comes hand in hand with the condensation-free feature discusses above. The leak proof feature keeps the body of the flask dry.
6. Lid/mouth Type
The snap-on lid is preferable when it comes to the type of mouth opening of a flask or bottle. Because it is narrow and the liquid can be easily poured out into some other container thus making the process hassle-free and spill proof.
The presence of a wide mouth sometimes results in the spilling of the liquid especially if you are traveling in a car or are in some other transport movement. Thus, the snap-on lid is a preferable choice when it comes to lids.
Also, lids come with a cap which acts as a mug when inverted. This solves the problem of carrying extra cups when you are on a solo trip or you are at the gym or office.
7. Easy to clean
Thermos flasks or bottles which have a wide mouth are easy to clean compared to the ones which have a narrower mouth.
The exterior body of the flask can easily be wiped clean with water because it is made of stainless steel. But to remove the odour from inside, it has to be swiped or cleaned with mild soap and a soft sponge.
8. Warranty
Last but not least. The warranty period of the product should be checked before purchasing the product. The warranty card should be issued properly after purchasing the product so that the benefits of the warranty period can be earned.
Frequently Asked Questions (FAQ’s)
Ans. Thermos flask or/and bottles can hold both hot and cold liquid or beverage. However, carbonated drinks are not to be poured inside, for most flasks. Apart from that any favourite hot/cold beverage of yours can be poured inside.
Ans. No, the steel used in making the body is not some random cheap bad quality steel. It is stainless steel. Most flasks and bottles use the 304 food-grade, BPA-free, and 18/8 quality stainless steel which is the best among stainless steels.
It ensures that no toxins or chemical substances mix with the liquid inside. The stainless steel also promotes the durability and longevity of the product.
Ans. Bad odour can be removed from the flask by simply cleaning it. The exteriors of the flask can be wiped in no time. For the inner part of the flask, a mild soap can be used and the cleaning can be done using a soft sponge or cloth.
This way, the odour can be eliminated. The exterior case in some flasks can be washed too but again with mild soap and lightly (not vigorous washing).
Ans. It is advisable to wash the flask with your hand and mild soap. But some flasks can also be washed on the first rack of the dishwasher. But, it varies from flask to flask.
Ans. A Thermos flask can be used in microwaves. However, the lid should be opened before putting it in a microwave. Since the wall is thick enough and double-walled, the liquid inside it will a take a long time to warm.
It is better if the flask is not used in the microwave. Thermos flasks or bottles can also be put in the fridge/freezer. It will perhaps take a longer time to freeze the content inside as well.
Ans. Thermos flasks or bottles are available both online & offline. Some of the best brands include Milton, Borosil, InstaCuppa, etc. These brands sell their products both online and offline.
