“Hot thermos” and “Cold thermos”
Recently, as the number of people who enjoy outdoor activities such as hiking and camping has increased, the demand for thermal and thermal bottles that allow them to conveniently enjoy drinks outdoors is increasing rapidly.
But what is the difference between the thermos and the bottle that we commonly use?
There are several differences in apparently similar thermos and thermal insulation bottles, and if you understand each use well, you can use it more conveniently according to the function.
According to the industry on the 27th, the scientific principles of thermos and insulation bottles are basically similar.
Although it is an ordinary water bottle on the outside, the outer wall is designed using glass or copper-plated stainless steel materials with low thermal conductivity to prevent heat movement through conduction, convection, and radiation.
This is why thermos is called Vacuum Flask.
In case of vacuum treatment between the outside and the inner outer wall, conduction and convection do not occur without air.It is a principle that blocks external heat and keeps drinks warm or cool for a long time. Since it has been vacuum-treated to prevent heat movement, most thermos can also be used for cooling functions, and it is true that the thermos also has a certain degree of heat.
However, the thermos must maintain the temperature of the contents, and the double cap structure of the inner stopper and outer lid and a double-wall structure.
So you must drink the hot contents according to the cup.
Most thermos bottles adopt a one-touch stopper format so that they can be drunk little by little according to the lid or container to protect users from hot contents, so the weight of the lid is a little heavier than that of the bowl.
On the other hand, since one cap (one-touch cap) can be applied to the bottle, the difference is that the cold contents inside can be consumed immediately after opening the cap.
Borang bottles, which usually contain cold drinks in summer, are often designed in a streamlined manner with wave patterns to enhance grip.
An official from Samgwang Glass said, “The thermal insulation bottle usually uses a two-layer body vacuumed in the middle, but in addition to this structure, the thermal insulation bottle also uses aluminum single layer materials.”
In the case of a cold bottle, 3 to 5 degrees of water is put in a cold bottle left at room temperature (18 to 22 degrees Celsius) and left for 6 hours, and both the hot bottle and the cold bottle must pass the state-set regulations to be sold.
The Lock & Lock product development headquarters said, “The thermal and thermal bottles are made with the same scientific principle, but the difference in design takes into account the user’s convenience and contents.”
On the other hand, no matter how good a thermos or a cold bottle is, it can be used semi-permanently only by disinfecting a spoon of soda in warm water once or twice a month without covering it, or leaving it in warm water with 1 or 2 drops of vinegar for 30 minutes without covering it.
In addition, depending on the purpose of the interior, if you increase the temperature with hot water or cool it with cold water, respectively.
