Criteria Used for Evaluation
The first criteria that we considered in searching for the top ten thermos bottles were the overall quality of construction and the materials used. We knew that in order to pass our standards, the bottles need to be constructed of high-quality material, have superior workmanship and quality, and also be able to withstand the rigors of your use. Add to that, the materials used also need to be safe. After all, the contents of the bottles are going to be used in the consumption process. The last feature desired was contamination.
Thankfully, and expectantly, every example on our list met these criteria with flying colors. The materials used primarily consisted of food-grade stainless steel or better, BPA-free plastics, and construction styling that made it very difficult for microbes or germs to be spread with proper hygiene and use.
Let’s face it; it doesn’t matter how spectacularly a thermos mug is constructed if it doesn’t get used right? Well, that’s why the ease of use was another important factor we considered. In order to determine how easy it was to use, we considered the overall size of the mug, whether or not there was any handle present, if the bottle had a no-slip grip or ergonomic design, and whether or not the spout allowed for easy pouring, drinking, or the addition of materials such as ice cube.
While many of the examples presented met most of the criteria presented, very few, such as the Zojirushi and the Life sky met all our demanding ones. That being said, some like the Camelbak chose to specialize more, meaning that they excel in certain areas more, such as ruggedness and long-term use. Each one, however, was shown to be perfectly adequate for every use by the average person.
Of course, another important factor that we considered was the size to capacity ratio of the bottles. In most cases, the volume held by the bottles were pretty close to their overall size. This means that for the most part, a person using these bottles would get the most fluid for their money as it were. Making sure that each bottle can carry a good amount for a beverage whether you are on a run or running errands and that it is enough to keep you hydrated is important. A larger bottle with more capacity can be great for long drives or long drives as you are able to hold a good amount for you. Or if you are only wanting to go on a shorter run it is important to have a mug that only carries a smaller amount so that the bottle can fit nicely in your hand and that it is not too heavy.
When it comes to the great outdoors and the people that love it, how long a piece of equipment lasts is an important factor to consider. Thermos bottles, of course, are no exception. Thankfully with the standard stainless steel materials used, and the quality construction, pretty much every example on our list is built to last. Another factor that many people don’t take into consideration when buying a thermos is whether or not they’ll be able to use it properly. If you suffer from arthritis or other joint problems, so thermoses might be too hard to open or use effectively. Also, if your hands are relatively large or small, some handles might not be so well suited for your grasp. So make sure you consider all of your options before settling on one particular thermos mug.
Expert Interviews & Opinions
High-quality thermos bottles come in a myriad of different shapes, sizes, and styles. In fact, there is probably one that is just perfect for every outdoor enthusiast out there. However, with so many choices on the market, it can be a little daunting to find the right one for you. One of the first things to consider is what your overall lifestyle is like. Are you an active person who spends more time in the great outdoors than inside? Do your outdoor adventures take you to far-flung places for days at a time?
Thermos mugs, just like any other piece of outdoor equipment need to be maintained properly in order to ensure that they function well for quite some time. Unfortunately, in the case of thermos mugs, this often means frequent hand-washing, an inspection of parts, and making sure that they are used correctly each and every time. While many of these thermos bottles are designed to withstand the rigors of constant use, they do have their limits. So when you’re looking for one to use, make sure you understand and are willing to follow the manufacturers' directions when it comes to general use and maintenance.
Other Factors to Consider
Truth be told, for many people, the overall price of the thermos bottle is perhaps one of the most important considerations they take into account. These bottles range in prices of a decent lunch for one all the way up to a five-course meal. Thankfully, there are good contenders in nearly every price category imaginable. So whether you are looking for something that is a little more budget friendly, or you are willing to spend a few more dollars, chances are you’ll find a quality choice in this list.
If you are planning on storing some food in your thermos for lunch or a quick snack while on the go, remember that the only way to keep your food hot is to have a little liquid in the thermos with your food. That is why soups are the best thing to store in your thermos for lunch, as it will be able to stay warm all day long.
Frequently Asked Questions
q: How should I care for my thermos mug or vacuum flask?
In most cases, the most important thing is to make sure that you clean your thermos bottle on a regular basis, specifically after each use. Most manufacturers recommend hand washing, some of them to allow for use of the top-rack of a dishwasher for some parts.
In most cases, a simple rinse with water after each use and a wipe with a damp sponge can be all you need out in the field. Once you get home, take the thermos apart completely and wash in hot, soapy water. Make sure to rinse the soap away completely, and dry the thermos thoroughly. Doing so ensures that the seals are maintained, and helps to prevent leaks from occurring.
It’s also a good idea to regularly inspect the gaskets, seals, and smaller parts for wear and tear and replace them when needed. Finally, make sure that the thermos bottle isn’t put through too much abuse.
q: What is this BPA that I Keep Hearing About?
BPA stands for Bisphenol A. It’s an industrial chemical that has often been used in plastics and resins since the 1960s. While it was originally thought to be safe for human consumption and use in food grade materials, more recent studies have changed our understanding.
It is now indicated that this chemical may affect the brain, behavior of individuals, and the prostate glands of fetuses, infants, and young children. Studies have also indicated a possible link between BPA and high blood pressure. Given the mounting evidence of problems with BPA use, many thermos bottle manufacturers are starting to move away from using it in their products
q: How Does a Thermos Bottle Actually Work?
A thermos bottle helps to keep the temperature of your beverage inside cold or hot because it is insulated against heat loss (or heat gain) through the use of double wall construction. Essentially the thermos bottle works in much the same way as the double paned windows of your house. They use the air that is trapped within the two walls of stainless steel to help minimize the transfer of heat.
This concept is highly innovative and has been with us for a very long time and innovative ideas to come up with better do exist but the traditional style remains very popular. The outer skin is usually a durable flask coat which can take knocks but the inner skin is fragile and if damage does occur it is usually the inner that breaks and this renders the flask useless. Depending on the design it is possible to replace a broken inner.
q: What is the best size Thermos Bottle for Me?
The answer to that depends greatly on what you’re going to use the thermos bottle for. If you’re going to be using it for daily use, a smaller size may be more than enough. If you want to use it on longer outdoor excursions, a larger, more robust size may be in order.
If we took a technical stance to this question we would suggest you consider age and size, a larger person working outside all day will most certainly want a flask which can carry a good volume of liquid. A school student would take along a medium sized flask because he/she is only looking to drink at lunch hour or during a break from classes. There are mega flasks which are very good for group picnics and these flasks will carry a large volume of liquid which is generally enough for an averagely sized family.
q: What can I do to make sure I get the most out of my thermos?
If you want to make sure that your cold drink stays ice cold, or your warm drink can still warm your bones after a few hours, there is a bit of preparation that you need to do. Thankfully, it’s a fairly simple process. Depending on what your desired temperature is, you’ll need to either pre-heat or pre-chill the thermos bottle. First, if you want to pre-heat the bottle, open it up and pour in some boiling water.
Let it stand for a few minutes. This allows the heat of the boiling water to radiate into the trapped air, heating it up slightly. That way, any heat lost from your drink will be replenished by the heat trapped in the double wall construction. Conversely, if you want to make sure your drink stays cold, allow very cold water to sit in the thermos for a few minutes to chill the air or add ice cubes to the thermos prior to use.
