Smash Stainless Steel Push Button Food Flask, Sage

Product Information

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. A Thermos King will last years but it’s not officially dishwasher-safe, and you’re not even meant to submerge it in water (if you do, you kill the manufacturer’s 50-year guarantee). Inquisitive users report that it does survive the dishwasher intact, albeit with peeling colour. For the kids’ lunchbox – The Food Flask from IGZOM is a great choice for kids thanks to a wide range of colourful and cheerful designs. It has plenty of volume (540ml) and heat retention capabilities (up to 6 hours hot) to keep food warm all the way to lunchtime and is compact enough to fit into a schoolbag without taking up too much room. Food Flask Buying Guide

Best for big meals – SHO’s Ultimate Food Flask is not the biggest flask out there, but it is bigger than most. 2 sizes are available for the Ultimate, both of which are bigger than comparable flasks. The smaller is 600ml, which beats out other similarly sized flasks which are usually around 500ml, and the 800ml compares with others usually around 700ml. So unquestionably, if you’ve got a big appetite (or are carrying food for two) then the Ultimate should be your flask of choice. An honourable mention does go out to Pioneer’s 1000ml food flask, however. Best quality & features – The Thermos Stainless King Food Flask proves why Thermos are the standard when it comes to flasks. The durability and build are second to none, something which is exemplified by Thermos’ 50-year guarantee. Although not the largest flask here, the excellent heat retention times of up to 9 hours (hot) and up to 12 hours (cold) are among the best out there for a good-sized single portion of food. The colour options are a nice bonus, too. High-quality thermal flasks can keep food and beverages warm for as long as a full 24 hours. More economical brands will typically retain the original temperature of contents for four to six hours. Even inexpensive models tend to be vacuum-seal stainless steel. However, the vacuum-seal method can be used with other materials like glass and plastic. Because they are not as durable as stainless steel, they are not recommended.Our home tester liked the double-wall insulation and its compact size since adults can also use this for hot sides and drinks. But our reviewer focused on one of the most important aspects of a thermos: How long will it keep your food hot? Thermos claims that this keeps food warm for up to five hours, and it fell short in our tests. Mac and cheese only stayed hot for two hours, was still warm enough to eat at four hours, and needed to be microwaved (in a separate container) by hour five. When it came to cold liquids, it did live up to its nine-hour claim, with ice cubes still present after a full workday. When it came time to clean up, our tester noted that though this is dishwasher safe, you might be better washing it by hand. There was food caught in the lid, gasket, and the container necessitating a scrub-down with a sponge. On a budget – The 720°DGREE wunderJar Food Flask makes for surprisingly good value for those not wanting to overspend on a food flask. Even with its environmentally-friendly credentials, which often come with a little extra on the price tag, this particular flask is very reasonably-priced for a flask with a solid amount of volume for single portions and exceptional build quality and style.

Multi-wall insulation: Double-wall insulation creates a vacuumed layer, which is vital for keeping hot drinks hot and cold drinks cold. Some flasks include more layers for even better insulation. The 100% stainless steel construction of today’s flasks means there’s no risk of inner walls shattering when dropped. UP TO 6 HOURS COLD: Keep your cold food crisp and fresh for up to 6 hours in 500ml and 5 hours in 300ml. Perfect for sunny days out at the park or on the beach. No need for a separate cool bag, just grab your pot and go!

Some flasks are also designed with the intention of maintaining a low temperature for cold food. While not fully refrigerating them, flasks designed for this purpose will usually keep things cold longer than they keep things hot. But, some flasks are not meant for this, so bear that in mind. verifyErrors }}{{ message }}{{ /verifyErrors }}{{ The lid can be a major functional part of any kind of flask. Just like drinks flask which utilise the lid as a miniature cup/mug, so do food flasks have convertible lids. It might be a pertinent consideration, especially if you’re getting a food flask for camping or hiking trips, to have a flask with a lid that doubles up as a bowl. Some also come with foldable spoons, meaning cutlery becomes one less thing that you have to bring. Materials Thermos is synonymous with the product it produces—thermoses. But unlike Kleenex and Tupperware, Thermos has not been able to maintain the trademark on the term "thermos." The Thermos company, first started in Germany, was the first to figure out how to take industrial vacuum-sealing techniques and apply them for home use. Today, Thermos makes a wide range of insulated containers, from flasks and mugs to coolers and lunchboxes.

It's imperative to strictly adhere to the instructions for use, such as warming the interior with hot water for five to 10 minutes before adding any food that will be eaten later. Our home tester found that when you did, this kept hot food warm for five hours, even if it was opened every hour to test the temperature. It also kept cold beverages cool for seven hours, with ice cubes still visible at the end of the test. Thermos King states this can keep liquids hot for nine hours and cold for up to 14 hours, so we put that claim to the test in a home kitchen. Our reviewer filled all 16 ounces with freshly made mac and cheese and opened the thermos every hour to see if the temperature remained consistent. It wasn't until the ninth hour that the temperature dipped. Additionally, it excelled at keeping water ice-cold, with our tester still observing ice cubes after 14 hours in the thermos. Using a stainless steel vacuum-sealed design, an inner flask maintains contents at a consistent temperature, since warm or cold air cannot easily penetrate or escape from the flask. The outer material, usually made of hard plastic or steel, allows the thermos to be comfortably held and transported without liquid leaking out.It’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
