Stanley 10-01229-003

Reliable and Time-proven Classics

With all the innovations and technologies conquering the world, there are items that remain relevant and highly demanded in their original design worked out many years ago. They are so good in their initial form that hardly needs any updates and set quality standards for the next models. The Stanley food flask is exactly that type of item. Now a globally renowned manufacturer producing a whole range of stainless steel lunch boxes, travel mugs, and food and drink flasks for a variety of eating needs, Stanley was established in 1913 and started from the first all-steel vacuum-insulated bottle with an airtight cap on the top. Since then, the company has brought to life many innovations and realized a lot of smart solutions in its products, yet its Classic series in a legendary hammertone green is still a cornerstone of the brand and has not changed much for generations.

Featuring a standard oblong thermos design, the Stanley Classic Food Jar is a great choice for outdoors and job sites. It will easily fit into your backpack, bag, daysack or even sit over your toolbox. However, unlike original thermoses with glass inner containers, this model boasts an unbreakable all-steel construction. The material is absolutely food safe and ensures exceptional item durability and longevity. Besides, while a standard thermos with a narrow mouth opening is mainly meant for liquids, the Stanley flask has a wide mouth opening that makes it suitable for foods as well. The Stanley double vacuum insulation technology will keep the jar contents hot or cold for up to 15 hours. Meanwhile, a capacity of 720 ml is enough for holding two portions of food or three cups of beverages. An insulated lid securely seals the flask preventing leakage and doubles as a bowl saving you the trouble of carrying any additional dishware for having a meal on the go.

Supported by a lifetime manufacturer warranty, the Stanley food jar stands out for time-proven quality and a rugged stainless steel design, giving you an opportunity to enjoy your deliciously hot meal whether you are in the mountains or at work site.

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.
