ThermoCafe by Thermos Food Flask 400ml Vacuum Insulated Travel Mug & Spoon

Product Information

Since the American manufacturer, Thermos, came to fame, the term has become slang for vacuum-insulated flasks. Although the terms are largely interchangeable, the original scientific phrasing is 'vacuum flask'. Keep your hot and cold beverages handy when on the move with our range of flasks. Our range offers a great variety of sizes to meet all your needs. Choose from an array of trendy designs and carry yours in style. Whether you want to bottle up drinking water or are looking for a coffee flask and a tea flask to enjoy your favourite beverages on-the-go – there’s a flask bottle in store for everyone. Many designs come with a reusable coffee cup which can be put to multiple uses. Definitely a better alternative to single-use options. Or you can go for a practical travel mugfrom our collection.We’ve got something for the kids too.

Don't leave food and drink in a flask for a long period of time Bacteria can breed and this produces gas. Pressure then builds up which can force the lid off the flask. Capacity: Bigger capacity means more contents to enjoy. It also means more weight to carry, but only if you fill it to the brim. For best insulation, buy a flask that’s slightly bigger (but not heavier) than you need, and leave a couple of centimetres of air at the top. We’ve included capacity and weight info for all our flasks below.They also win big on green points, doing away with the need to buy drinks in single-use cups. If your flask is big enough for lunch you can save on both money and plastic. Need to know: Not dishwasher safe, twist-off lid, glass and plastic materials, comes with two cups, also available in 1.8-litre size

The two glass-lined flasks we tested were the only flasks to fail our drop test: one shattered on the first drop, the other fell apart on the second. Angle tough-to-open flasks away from your face Also, do it in an open space as this will protect you and others. Insulated cup: Good flasks also pay attention to the insulation of the detachable cup, if they have one. This is so your drink stays warm while you’re drinking it. Meanwhile, the outside stays cool, so you don’t risk burnt hands. The space between the two flasks creates a vacuum, as labelled above, preventing heat transfer. The wall of the inner flask is silvered to prevent heat radiation deflecting heat away from the flask. Need to know: Not dishwasher safe, button-operated lid, comes with one cup, also available in 350ml and 500ml sizesWhether it’s a chunky “food flask”, sleek “vacuum bottle” or something in between, the job of a flask is to keep food and drink hot or cold without leaking, all day long. Some of the winners on our list can insulate for more than 24 hours, which is long enough to survive the toughest hike or most gruelling commute. There have been reports of vacuum flasks exploding during use. Although rare, if you're not following proper guidelines, it is possible.

Textured coatings are useful – it’s a nice touch to have a handle on a drinks flask but generally, for a one-litre flask, it’s more useful to have a textured coating that provides grip. Thermocafe vacuum insulated food flask keeps your food fresh for longer. Handy metal folding spoon includedIt’s 100% leak proof – no matter how hard we tried, we couldn’t get any liquid to escape and the automatic opening trigger means you can drink from it one-handed with ease. Finally, there’s an additional loop handle on top so it can easily be attached to bags or simply carried this way. All in all, this is brilliantly stylish and robust We dropped each flask five times from 90cm to mimic a dropped flask. Those with large dents that inhibited function or ability were rated low. Thermos designed the flask to be as light and ergonomically comfortable as possible, with a cool sweat-proof exterior. It can’t match the Stanley Master for sheer insulating power (no flask can, to be honest) but it still does a great job of keeping cold drinks cold for a couple of days, and hot drinks piping hot all day.

We examined each flask and its pouring mechanism and attachments for faults. We penalised flasks that had faults affecting their usability. Flasks are more 'smell prone' than 'stain prone' – none of the flasks we tested had any staining after cleaning, but some retained a faint coffee smell. We've reviewed the best Thermos flasks, along with vacuum flasks from Chilly's, Stanley and Hydro Flask, and cheaper own-brand products from Wilko, Asda and Argos We hand-washed each flask with hot soapy water and let them air dry overnight, then ranked them on smell.Invest in a sturdy bottle brush for stainless steel flasks – it will help you get to hard-to-reach areas inside the flask but could damage glass-lined flasks
