Healthy Eating is Not a Hassle Anymore

With a healthy lifestyle being a modern trend, more and more people turn to a healthy diet and proper nutrition regimen. However, with busy everyday schedules, many find it hard to stick to their diets and eat their three meals daily often replacing a substantial hot lunch by cheese and ham sandwiches, yoghurts, some protein snacks or worse, by fast food meals they consider light. And even if you have an opportunity to have lunch in a cafe from time to time when running errands or having a business meeting, you’ll be constantly tempted to eat something that does not align with your healthy menu. The easiest and the most cost-effective way to stick to your healthy eating habits, especially if you try to lose weight or need to follow a specific diet due to some health conditions, is to eat homemade foods. With a variety of modern kitchen appliances available on the market today, cooking is not that time- and effort-taking anymore and the Thermos King Food Flask will help you keep up with your proper nutrition schedule.

Using the branded Thermos vacuum insulation technology invented over 100 years ago, this food container will keep your meal warm until you are ready to eat saving you the trouble of heating it up. And no need to worry that your foods might get spoiled. The capacity of this model is 500 ml being enough for a substantial meal. An air-tight screw out cap adds to overall insulation efficiently locking in the warmth and prevents any leakage or spills allowing you to easily transport soups, pasta, stews, or roasts. The thermos will keep all your dishes deliciously hot for 9 hours while the storage period for cold foodstuff is 12 hours. Meanwhile, the exterior will stay cool-to-the-touch with hot contents and sweat-proof with cold.

Made of first-class BPA-free stainless steel, this thermos flask is highly resistant to impact and corrosion and will serve you for many years to come.

GOOD FOR YOU 530ml

For All Sorts of On-the-Go Use

Fast-paced modern life leaves many of us little to no time for full-scale meals during the day. On the other hand, healthy eating trends call for sticking to a well-set eating regimen and consuming fresh nutritious foods. Thermoses or thermal containers offer a perfect compromise in this concern allowing us to have a healthy meal wherever we are without much fuss and preventing us from surviving on snacks and fast food during the day. Yet, not all food flasks are equal. So, if you want a thermal container that combines quality and versatility, you can’t go wrong with this model from GOOD FOR YOU.

LFGB and FDA certified, the model really excels in quality. Those certificates prove that it is entirely made of food-safe materials free from any hazardous components that might be potentially harmful to your health. Thus, the interior and exterior are made of 304 stainless steel that will confidently resist moisture, rust, and corrosion and can be safely exposed to any type of food and drink. The lid and closure, in their turn, are made of BPA- and phthalate-free plastic resistant to heat and mechanical damages. As such, the jar will easily withstand the test of time and promise long service life.

The insulation technology applied in this product also deserves close attention. The jar walls are a multi-layered structure lined with an electrolytic lapping technique and featuring copper and insulation layers in between steel plates to maintain a consistent hot or cold temperature. Such a pie-like system combined with a vacuuming closure works wonders to keep your foods and drinks deliciously hot for up to 9 hours and refreshingly cool for about 24 hours.

Up-to-par temperature maintenance and leakproof qualities come packed into a smart travel-friendly design. At a higher 530 ml capacity, the flask boasts quite compact dimensions and is fitted with everything you need to conveniently have your meal on the go. A lid neatly accommodates a foldable spoon and will also double as a bowl. A silicone lining on the bottom will prevent the flask from sliding and skidding. And a draw-string bag included in the package allows attaching the container to your backpack during travels or camping.

All things considered, the GOOD FOR YOU food flask is good for all sorts of on-the-go use, whether you need to pack a hot lunch for a kid, take some meal for yourself, or carry fresh foods or drinks with you when hiking, picnicking, backpacking, or travelling.

720°DGREE wunderJar

Smart and Quality Design

Packing your meals into a thermos instead of using disposable plastic dishware is one of the effective and easy ways to cut down your environmental footprint. With that in mind, in 720°DGREE, they’ve created a so-called “wunder Jar” food flask. Distinguished by top-quality steel design, this flask uses the best technologies and will serve as a substitute for disposable dishware, pleasing you with flawless performance for years to come.

To start with the materials, the 18/10 stainless steel the unit is made of is super durable and not prone to deformation. It won’t oxidate when exposed to acidic foods and won’t leach any potentially dangerous chemical compounds to your treats under scalding hot temperatures. Meanwhile, the dual-wall design ensures perfect thermos effect to keep heat up to 9 hours and maintain cold up to 16 hours. Besides, featuring the KeppDGREE technology, the model has an additional copper layer in between steel walls to further enhance heat retention and keep your meals and beverages initially warm or hot and cool or cold.

A perfectly insulated flask, the 720°DGREE wunder Jar also boasts vacuum closure that perfectly traps all food tastes and flavours inside as well as eliminating the risk of spills and leakage. To achieve that, the flask's been fitted with a special pressure-relief system that activates only by pressing the button.

A 450-ml flask capacity is not a lot but will be enough for regular daily use. For those who need bigger portions, a larger 650 ml thermos is also available.

To end it up, the 720°DGREE wunder Jar is a smartly designed and cleverly engineered food flask distinguished by premium German quality and ideal for long-term use.

What Is a Food Flask?

A food flask or food thermos is a compact insulated jar consisting of the inner chamber and an outer container with vacuum in between. The whole system is sealed with an airtight stopper. Such technology allows preserving the temperature of foods and drinks for a time period up to 15 hours. Initially, the inner jag used to be made of glass. Yet, due to its fragility, in modern food flasks, the inner chamber is most often made of hygienic, durable, and wear-resistant stainless steel. As for the outer container material, most often, you will come across stainless steel or food-grade solid plastic. With a capacity varying from about a cup volume to 1 litre, thermos flasks are usually suitable for keeping both foods and drinks.

The scope of use of food flasks is really impressive. It will become a handy complement to all your outings allowing you to share a cup of hot chocolate with your partner or friends when sitting near the fire during camping, enjoy a glass of flavourful mulled wine between exciting skiing sessions in the mountains, or cook some food over the fire and store the leftovers in a thermos food jar when backpacking. Apart from seasonal outdoor activities, food flasks will be of great use in everyday life. With a food thermos, you can always enjoy a warm healthy meal at work which is especially important for those prone to food allergies or sticking to a strict diet who cannot often eat out. Besides, a thermos flask will let you pack a nutritious warm lunch for your kids making a good alternative to sandwiches they might be bored of.

If you are into healthy eating yet do not like to spend much time in the kitchen, you will definitely appreciate the benefits of a crock pot cooker that will help you diversify your healthy diet, meanwhile, saving your time on cooking.
