Thermos Flasks For Warm Drinks

If you need a thermos flask for bringing your coffee, tea, and other beverages with you wherever you go, you should purchase a good quality flask for warm drinks. The majority of thermoses can be used for both hot and cold drinks thanks to the double walls of the flask. This design provides great insulation for both hot beverages (keeping them warm for up to 12 hours) as well as for cold drinks (because a good quality flask will make sure that they stay chilled for a long time).

The great thing about these flasks is that they usually have a tight seal that will prevent any leakage and keep the other things inside your bag dry. Some of them even come with a cap that can also be used as a mug, which is great for when you want to go camping and want to bring a larger amount of coffee for you and your friends/partner. This type of thermos flask can be really practical to have in your car since most of them will fit the cup holder; you can enjoy a warm beverage even when you’re travelling a long distance.

It is an ideal product to transport your drinks when you’re travelling, watching sports, relaxing outdoors, or just running errands. The cup that it comes with makes it easier to enjoy your drink. It is also a great product for all of those mums who want to prepare milk or formula for their babies to have it ready on the go, since the flask will maintain the original temperature and since they’re BPA-free.

Features of Thermos ThermoCafé Stainless Steel Flask, 500 ml

This flask is made out of stainless steel in both the interior and exterior. The technology behind it is the stainless-steel vacuum insulation that cancels out any change in temperature by creating a space between the two walls. That way, you can be sure your drinks will remain hot or cold, while the flask remains sweat-proof with cold drinks and cool to the touch with hot ones.

The elegantly-designed flask comes with a stainless-steel cup that makes pouring your drinks much easier. The twist-and-pour stopper prevents leakage and allows you to pour your drinks without removing the entire top.

Thermos Flasks For Soup/Food

There’s nothing better than having a homemade meal even when you’re at work.

Not only is it great for bringing to work but you can also pack lunches for your kids before they go to school. In this way, you’ll know that they’re having a healthy, homemade lunch.

Thermos flasks for soup and food are usually shorter and wider than the flasks for beverages; for practical reasons. It’s much easier, less messy, and more convenient to pour out the meal and eat it from a wider thermos. A lot of models on the market come with an included spoon for added convenience. The mouths of these flasks are much wider so they can easily accept spoons and forks for eating directly from the flask without making a mess. They are usually insulated with double walls, and this makes sure that your food stays warm for up to 12 hours, while the flask is still cool to touch and you don’t burn yourself when carrying it. It can also be used for meals that need to stay chilled, such as cold pasta or salads.

What to Look for in a Good Thermos Flask

We have already mentioned quite a few characteristics and features of thermos flasks; these remaining tips may be of less importance but they still matter. Some flasks can be priced a little too steeply for their capabilities; you might find yourself overpaying for features you do not actually need.

  • Size

    This one is pretty obvious: if you only need an extra cup of your desired hot beverage to get you through the day, you would most likely want to get the smallest available flask there is; maybe even consider getting a thermal mug. If you need a thermos flask to bring a lot of hot tea on a family trip to the mountains during winter holidays, you might want to consider getting a bigger one. Keep in mind the actual volume of the flask can differ from what is on the label – if it says your flask can fit a litre of liquid in it, it might fit anywhere between 950 and 1070 ml, which means measurements can deviate from 50 ml to 70 ml.

  • Ingredients

    Bisphenol A (BPA) and phthalates are both fairly common in everyday household items, but their amount must be within certain limits as prescribed by law. Both of these compounds can cause the disruption of endocrinal function and might even be linked to obesity, so you should always check the label carefully for the amount of these in your thermal flask (and anything else, really). Lead is also known to be dangerous to humans if found in relatively high amounts, which is why you should try to avoid getting a thermos flask that includes even the slightest amount of lead, even if it’s within permissible limits. Note that it is quite possible to find thermos flasks that are entirely devoid of these three possibly dangerous elements.

  • Soda-friendly

    This problem might sound a little banal, but it can be a real headache for soda lovers: some thermos flasks cannot retain the bubbles and fizziness of your drinks, even if they can keep them ice cold. So if you like drinking carbonated beverages, you might want to check on this.

  • Cap type

    The cap is as important as the rest of the flask, if not more. If the cap is damaged or low quality, the rest of the flask could be of double-wall vacuum insulated stainless steel and still fail to retain the temperature of your beverage, or might also leak! The best type of caps are the screw-on ones – bonus points if they have additional valves or other ways to make the cap stick tighter. Different types include flip lids, tumbler lids, straw lids, corks, and tumbler straw lids.

  • Maintenance

    Thermos flasks generally don’t require much maintenance, but you still should be careful in handling them. The golden rule is to hand wash them. Although some newer, dishwasher-safe models have recently appeared on the market, it would still be best to clean these gently under a stream of lukewarm water without using any heavy chemicals like bleach. Also, no rough scrubbers to rub away at their insides, as this can cause damage. Glass flasks are pretty low maintenance – the only thing you need to do after washing them is to keep them full of water while not in use to prevent residual odour from appearing and also to make sure you do not break them. Stainless steel flasks are the safest ones to use because of their antibacterial properties. They are to be cleaned only with a mild detergent and a soft bottle brush and should also be kept with their lids opened to prevent odour. They also require a certain pre-conditioning; if you are going to pour hot drinks inside, you will need to pour in some hot water beforehand to prepare them. Or vice versa – cold water for cold drinks.

  • Price

    It is understandable that sometimes making a costly investment seems like the best option, but before you spend 50$ on a thermos flask, step back and think about what it is that you need from it. If you realise you won’t be needing it to keep your drink warm for over 6-8 hours, you don’t have to buy one of those very expensive, super high-performance flasks. A simple single-wall flask might do the trick if you don’t need your water to stay ice cold all day long.

  • Brand

    This is just more or less common sense, and it goes for anything you are buying. The brands with the most positive reviews out there are Nayasa, Eagle, and Thermos, but that does not mean others are less reliable or produce lower-quality thermos flasks. Your ideal purchase depends mainly on what you need from the flask.

  • Infuser/water filter

    One of the most popular additions to thermos flasks is a tea infuser/water filter. There have a filter near the top which allows only liquid to pass through, leaving everything else – tea leaves, for instance – away from the remaining liquid in the bottle.
