From The Manufacturer

The THERMOS brand is well known as the quality and performance leader in insulated food and beverage products. The Stainless King series creates a new chapter in THERMOS' storied history with a modern line that blends out newest technology with a dash of the past. An ideal choice for people on the go, the Stainless King Vacuum Insulated Food Jar is built to last and loaded with features to make for a more enjoyable eating experience. THERMOS vacuum insulation technology virtually eliminates temperature change within the food container by creating an airless space between two stainless steel walls. The result is an insulation layer that performs better than any other. A superior insulated container you can depend on to keep your food hotter, colder, fresher, longer. This food jar keeps items hot for 7 hours or cold for 9, making it a great choice for long days where mealtimes might be a little irregular. Constructed with double wall stainless steel, this 16 ounce food jar is virtually durable, yet its sleek design is both eye-catching and functional. The contoured body shape is easy to grip and the wide mouth opening is easy to fill, eat from and clean. The lid serves a dual purpose by also functioning as a serving bowl. The Stainless King Food Jar features premium, double wall vacuum insulation so the stainless steel body stays cool to the touch with hot items and condensation-free with cold items. Only the best materials are used to construct this food jar and are 100% BPA free. In order to maximize the incredible insulation technology, it is recommended to either pre-chill or pre-heat the food jar just prior to use. This can be accomplished by filling the food jar with cold or hot tap water, attaching the lid and letting it rest for a few minutes. Before you are ready to use, simply empty the water and fill with your favorite food item. Attaching the lid will further increase the thermal efficiency.

An Overview On Soup Thermos

Soup thermoses have a host of benefits that make them a must-have for every home. They save money by reducing the need to purchase lunch out, and you can also use them to practice proper portion control. Of course, their best feature is their ability to keep soups nice and hot and water ice cold.

As you shop for a soup thermos, take into consideration how long you need the liquids to stay hot or cold. If you’re heading out for an 8-hour workday and you want to consume a bowl of soup for lunch, you only need a thermos that stays hot for about 4 to 5 hours. Individuals who are traveling, however, would do better with a thermos that uses vacuum insulation technology to keep liquids hot for up to 14 hours and cold for 24 hours.

Check the capacity of the thermos next. Individuals can get away with a soup thermos that holds 12 ounces or less, while couples planning a picnic would do better with a 16- to 24-ounce thermos.

Look at the size of the thermos’s mouth and whether or not it comes with serving utensils. A wide mouth is ideal, as this makes filling the thermos easier and allows a person to eat directly out of the thermos. If the mouth is narrow, you’ll need a thermos that comes with a lid that doubles as a bowl. Some thermoses even include a foldable spoon, so you don’t need to pack a separate spoon.

Review the construction materials used to make the thermos. Stainless steel is an excellent choice, as it’s not only durable but also resistant to rust. Some models have a nonstick coating on the inside and a clear-coated exterior. Keep in mind that you want a thermos that stays cool to the touch and doesn’t sweat.

Once you know the thermos meets all your requirements, you can consider any extra features. For example, there are thermoses with attached handles that might make them easier to transport. You can also get thermoses in a variety of fun colors, including purple, cyan blue, pink, cranberry, slate and army green.

DWYM Fun Fact

It may surprise you to know that the thermos, originally known as a vacuum flask, wasn’t created to keep soup hot until your next meal. It was invented by Sir James Dewar, a Scottish scientist, back in 1892 as a way to store liquid oxygen at temperatures below -297 degrees Fahrenheit. The first model was made by placing a small glass bottle inside a large glass bottle and then removing the air from between the two bottles.

The Thermos brand was created just a few years later in 1903, with the first Thermos plant opening up in 1907 in Brooklyn, New York. Today, thermoses are made using a wide range of materials and sold in a variety of colors and sizes.

The Soup Thermos Buying Guide

  • If you accidentally screw the lid to your thermos on a bit too tight, you can use a round jar gripper to get it back open.
  • It’s a good idea to consider the weight of the thermos if you’re purchasing it for your child’s lunch box. You don’t want your child to have to lug a heavy lunch to and from school every day.
  • If your thermos has a slim mouth, you can use a funnel to help guide the food safely into the thermos without making a mess.
  • Consider preheating or precooling your thermos for 5 to 10 minutes with hot or cold water before adding your food or beverage. This step will help ensure your thermos stays the optimal temperature for many hours to come.
  • Wrap a strap with a plastic buckle around the handle of your thermos, then run it through the shoulder strap of your backpack so you don’t have to carry it in your hand. This is a handy tip for those who walk to work or school.
  • Cleaning your thermos after each use is important, as food can sometimes get stuck under the gasket. Check the thermos’s product care guide to determine if the parts are dishwasher safe. Many thermoses must be hand washed. You can use hot water, dish soap and a bottle brush to get the thermos clean.
  • Construction materials, design and size all play a role in the overall price of a thermos. The 16-Ounce Thermos Stainless King Soup Thermos and the 16-OunceDaCool Stainless Insulated Soup Thermos are among the most affordable models on the market. You’ll pay a moderate price for the 17-Ounce Stanley Classic Legendary Soup Thermos, while the 11.75-Ounce Zojirushi Stainless Soup Thermos comes in with the highest price tag.
