Thermos Buying Guide
If you like to drink hot coffee or tea, or you just like to spend a lot of time outdoors, a thermos is a good choice for you. And how to choose the best thermos is very important.
However, it is a little difficult to find the best one, because there are so many thermos on the market. Well, the first thing you need to consider is that what you plan to use a thermos for. For example, if you plan to use a thermos to hold a hot meal, you should choose a thermos with a big mouth. And if you need a thermos for hot tea or other beverages, you should choose a thermos that has a narrow neck, which can help you to pure the liquid easily. And, on the market, there are many universal thermoses. They come with several separate compartments. For example, a compartment is used to pour coffee or tea, and another bigger one is used to preserve a hot meal.
Once you have one, you can bring tea for a hike or a picnic. When it comes to buying the best thermos, there are some factors which should be considered.
Do you know what materials are used to make a thermos and whether they influence the durability and functionality? Here is the answer:
- Glass Chamber – The thermos’s chamber can be made of glass. Considering hygienic factors, glass is a good choice. It is pretty easy to clean, while the content can be preserved well. However, glass has a major problem that it is fragile. Therefore, if you choose a thermos that uses glass to build its chamber, you’d better avoid a clumsy movement, or it will break into pieces.
- Metal flask – A metal flask is a durable and practical alternative. Stainless steel is preferred to use. This is because stainless steel is corrosion-proof. And it is not so easy to break down.
- Plastic bottle – A plastic is not a good option. Poor plastic tends to retain heat, even if a special mirror coating is used. And plastic is also very fragile. It is prone to shattering and breaking.
The outer casing also uses different materials that have their own pros and cons. The plastic housing can help to reduce the overall height, making it portable to carry around. I think no people would like to carry a heavy thermos. Metals housing is corrosion resistant, making it more durable and practical. And this also means a solid construction. Of course, you also can choose a glass housing but it is not so practical, compared with the metal or plastic housing.
The second thing you need to consider is the volume of a thermos you would like to have. And this may be determined by many factors:
Do you just want a simple extra serving of tea or coffee or do you want to have multiple servings. Will you share your beverages with your family, friends or co-workers? And how far will you take it for a travel? And if you want to have an extra cup, you can buy a thermos cup. Generally, the more amount of liquid you will consume, the bigger thermos you will need.
The cap of a thermos is also very important. It must insulate the heat inside and will not allow to lose heat. If the lids are made of glass, they often are equipped with corks. However, it is not the best option, because this can cause imperfect sealing or leaking problems. An optimal choice is the screw cap.
Your budget is also crucial. Generally, the price determines the quality of a thermos. Well, this doesn’t mean high costs represent high quality, but at least you can likely find a high quality at a higher price. The price is influenced by its brand, materials used, volume and other extra features. Generally, you can find a good thermos if you would like to pay $24 or more.
- When buying a thermos, the following tips should be especially paid attention to:
- Take a good look around a thermos to check out any scratch or visible defects. If you find something bad, don’t buy it, because these problems can influence the performance obviously.
- Sniff the thermos. If there is any bad smell coming from it, this means it may use unsafe materials.
- Shake it. If there is any vibrate or sound, it is not a good thermos.
- Choose a good brand from a famous manufacturer.
- Check the cap and the cover carefully and a tight insulation is required.
