Tips for Choosing and Caring for Your Thermos

A thermos is a household appliance that functions to maintain temperature. This tool was originally only used to maintain the temperature of the water to keep it hot. But in its development, the thermos innovates and serves to maintain the temperature to remain cold, even to keep food to stay warm. The thermos was first produced in 1904. After that, many manufacturers make products with similar shapes. A variety of thermos products such as the best coffee thermos are sold with different specifications, quality, and prices. So, how do you know the quality of the product?

  • First, buy a thermos that has a well-known brand. No problem you have to pay more at the beginning of the purchase because its use can last for years.
  • You must ensure that the inner lining is in good condition and made of good material. For example, the interior material is made of stainless steel. This material is a rust-resistant iron compound. So it is safe to use and does not endanger health.
  • Also, pay attention to the outside. Make sure the tool is strong enough with a solid structure.
  • Another way to prove whether the thermos is quality or not is to direct the mouth of the thermos which is open and empty to the ear. Then listen to the sound. There will be sounds like the sound of the wind or like when we are diving underwater. If the sound is loud, the thermos has a good quality.
  • Choose a thermos that doesn’t smell. If you smell unpleasant odors, there is no need to buy the thermos. This indicates the thermos interior material is not good, causing an unpleasant odor.
  • Try to open or close the thermos. Does it close properly or has a disturbance that makes it unable to close properly. Because, as a temperature guard, this tool is very dependent on the design of structures and the use of appropriate materials.
