Have you always wanted an insulated bottle, but you don't really know which model to choose? Here are some tips that will surely guide you.
The strength and durability
of an insulated bottle depends above all on its material, which is why it is an essential criterion. You can choose between stainless steel and glass. The former is much more resistant and solid, which allows you to use the bottle for many years. In addition, you can easily find a beautifully designed model made of this material.
Glass is also more practical and aesthetic. It allows you to see how much drink is left in the bottle, without having to open it. In any case, whether you choose a stainless steel or glass model, it would not affect the heat of the drink, since there is a vacuum between the two walls. This vacuum prevents heat transfer.
The
closure system is a criterion not to be neglected. It is useless if the bottle is solid and aesthetic while it is not hermetic. There are generally three types of closure systems: with screw cap, snap-on and snap-off
. The snap-on closure system guarantees a 100% hermetic bottle. No drops will leak out when closed.
The
choice of size depends mostly on your needs. Compared to a simple water bottle, the isothermal bottle is much larger because of its double wall. You should then consider the size of your bag and the amount of beverage you plan to drink.
A 750 mL
bottle, while taking up a lot of space, is handy if you don't have easy access to hot or cold drinks. If you usually take tea with you, a 300 mL model is best. Obviously, if you drink more than 300 mL/day, you'll need a larger capacity insulated bottle.
As
there are many insulated bottles on the market, you should choose based on your needs, including how you will use them. They differ in material, capacity and design
. The choice is yours! If you plan to use it to carry coffee or tea, a small capacity model would be fine. On the other hand, you'll need a larger capacity if you want to drink a good amount of hot water or cold drinks during the day.
A
quality thermos flask is distinguished by its efficiency in maintaining temperature. In case you want to enjoy your hot beverage all day long, go for an insulated bottle with a temperature holding capacity for 12 to 24 hours. On the other hand, a lower temperature holding capacity would be sufficient if you drink the beverage within an hour.
By definition, the isothermal bottle, which can also be called a thermos bottle or simply a thermos, is a type of bottle with the capacity to keep a liquid at a temperature close to the initial one. It is composed of a cap that allows it to be airtight and often of a cup.
It is quite easy to understand how an isothermal bottle works. For optimal efficiency, the most commonly used method of temperature dispersion is by thermal conduction. It is the same principle as the James Dewar's vase and the basic principle of isothermics. It consists of a bottle, generally in stainless steel, which is imprisoned in another bottle of larger size. There is therefore only a minimum of contact, thus creating the double-walled insulating system. The air between the 2 walls has been emptied, offering a better limitation of the possible thermal exchanges between the 2 bottles.
When in contact with the liquid, the inner part cools or heats up quickly. If the air, by touching the outer bottle, is likely to cool it, this will have no impact on the inner container since there is no air between the 2 bottles.
Of course, you can differentiate insulated bottles by their closing system. However, this characteristic depends essentially on your tastes and on the use that you will have planned. That is why we have categorized the isothermal bottles in 2 main types, namely the classic isothermal bottle and the one more specifically designed for sportsmen.
With its long shape, the classic isothermal bottle has a double-wall insulation system that allows it to maintain the temperature for several hours. It stands out for its versatility and practicality
. Easy to carry, some models are equipped with a cord. Others are equipped with a tea filter, a fruit filter and an isothermal cup. In terms of opening and closing system, you will find on the market insulated bottles with screw cap and snap-on cap.
The insulated bottle is ideal for transporting hot and cold drinks with a good capacity to maintain the temperature. Available in various capacities, you can choose between individual use and family use models.
The
isothermal bottle for sports use stands out because of its opening system that is done by a simple pressure. You will therefore only need one hand. This type of bottle is perfectly suited for any type of physical activity: outdoor or indoor sports. Thanks to its well thought-out design, it is easy to drink directly from the neck.
Equipped with a specific cap, you won't have to worry about using it even if you are on the move. It is usually made of sturdy steel with a double-walled insulation. Its long shape makes it easy to carry. This type of model is equipped with an anti-leakage system and is often of individual format.
The isothermal bottle is as practical as it is easy to open. It keeps both cold and hot drinks very efficiently. It is made of stainless steel and has an easy-to-use spout. Unlike a plastic bottle, this one has a double-walled insulation and has an excellent temperature retention capacity (almost 12 hours for hot liquid and 24 hours for cold).
In some cases, it is even possible to insert ice cubes in order to obtain a very cold drink. Its remarkable watertightness, its sturdiness, its quality of design and its easy opening make it a product of choice. Note that the isothermal bottle has a larger capacity than an isothermal mug.
The isothermal mug is an excellent alternative to disposable cups. It has been designed with stainless steel, making it more solid and robust. Thus, it resists very well to shocks and falls. It has a spout that makes it easier for you to drink your drink in the best conditions.
Its double-walled insulation provides optimal heat conservation. Its biggest drawback? The coffee can become moderately bitter after several hours. Its capacity varies from 250 to 500 mL. The isothermal mug is very easy to clean.
Choose the insulated mug if you just want to take the rest of your morning coffee or tea with you. With its small capacity, it is also suitable for those who prefer to have a cup of hot beverages at hand and which do not get cold in the following minutes.
On the other hand, it is better to choose the insulated bottle if you want to take a larger quantity of water, hot or cold. Moreover, there are models equipped with a cup for a better comfort of use.
To take your hot drink everywhere
There is nothing more reliable than the insulated bottle to take your hot drink everywhere. It can be carried in a handbag or backpack. Whether you are travelling, on your way to work, at the office or on a hike, you can take it with you and drink at any time. The insulated bottles have been designed to be compact and waterproof.
To keep your drink warm or cool for hours
The main purpose of an insulated bottle is to keep a drink at its original temperature, hot or cold. It is a must-have accessory for tea, coffee and soft drink drinkers. The external temperature has no impact on the capacity of the bottle thanks to the vacuum between the two walls.
In winter, it can keep hot chocolate, chicken broth and any other hot drink for hours. Note that some models keep the heat in for 12 hours, while others can hold it for 24 hours. In summer, it can also keep your fruit drink cool for hours.
Apart from its practicality, the biggest advantage of an insulated bottle is that it can be used anytime and anywhere. It is not an accessory that is put away as soon as winter sets in or when the heat wave is at its peak.
It is environmentally friendly
Compared to a simple plastic bottle, there is no real comparison to be made since we all know the impact of plastic on the environment. As mentioned above, the insulated bottle can be used all year round. It doesn't produce waste and is reusable at will, whether it's stainless steel or glass.
For its versatility
With an insulated bottle, you will be able to take your cold or hot drink, even a large one, with you wherever you want. It is suitable for different activities besides the classic office use. Some models are designed for sports while others are suitable for travel... This type of bottle keeps your baby's milk better while you are on the move. It is also possible to keep mulled wine in it. In short, the isothermal bottle can be used in winter as well as in summer.
For its ease of maintenance
It is not recommended to put the isothermal bottle in the dishwasher. To preserve it better and allow it to last as long as possible, prefer more ecological cleaning products. A clean sponge is enough to clean the inside. Use white vinegar to eliminate bad odours. Dry it afterwards by placing it upside down on a clean surface.
In our opinion, the best brands of insulated bottles in 2022 are :
It is surely the most famous brand in terms of isothermal bottles. In fact, this name is now used to indicate this type of bottle. Being the originator of the product, the brand never ceases to receive praise for the quality and performance of its products.
A brand that markets products that are both practical and reliable, Wilford & Sons offers you its high quality insulated bottles. They are as easy to use as they are effective.
The Newdora brand products stand out for their ease of use. In terms of isothermal bottles, you will easily recognize them thanks to their automatic opening and closing system.
Concerned about the environment, the Qwetch brand offers durable insulated bottles. Among its wide range of articles, we find insulated meal boxes, teapots... Its insulated bottles are designed with stainless steel, a very robust and resistant material.
This German brand has been able to put forward its know-how by proposing products that are always as efficient. The isothermal bottles, in particular, undergo numerous tests before being put on the market.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Use a thermos flask to pack your food.
Use a thermos to pack dishes that contain sauce or liquid meals like stew or soup. A thermos can only keep food hot or cold if it contains sauce or liquid.
You can also carry cold or liquid food in your thermos.
Chill your thermos in the refrigerator or freezer. You can also fill the thermos with ice and water. Put the lid on. Let it sit for a few minutes to cool and then pour in the water. Once the thermos has cooled, quickly add cold food or drinks (to 4°C or below) and close the lid tightly.
Clean immediately after use.
Always clean your thermos when you get home. Drinks (or food) that you forget to consume will spoil and be harder to clean after a while.
Use baking soda.
To clean the thermos bottle, you can either use only baking soda or a mixture of baking soda and vinegar. Mix 1 teaspoon of apple cider vinegar and 1 teaspoon of baking soda with warm water. Let the mixture sit in the bottle for a while. Scrub the bottle and rinse well. The solution is better than soap and water and is great for removing odors.
Use a tea bag.
If you don't have baking soda, the easiest way to clean your thermos bottle is to use tea bags. Put a tea bag in the thermos bottle and add boiling water to it. Fill the bottle and leave the mixture in the thermos overnight. Discard the mixture in the morning and the thermos will be clean and spotless.
The best insulated bottle depends on your needs and your budget. Read our buying guide to find out which products are the best at the moment.
It is advisable to always pour hot water into the bottle before the hot drink of your choice. This will mainly serve to heat the walls, allowing your drink to keep its temperature close to the initial one.
The current models have an anti-spill system. However, if the cap is properly closed, there is no risk of the drink leaking. Prefer screw caps, which are more watertight.
On average, an insulated stainless steel bottle has a life span of 10 years. This material has the particularity of being very resistant over time.
Limescale, mineral and scale deposits are commonplace when you have an insulated bottle. To get rid of them, clean it with hot water and white vinegar. Let the mixture work for a few hours before rinsing and drying.
