After seeing this title, do many friends have the same problem? Why can the thermos cup only be a double-layer stainless steel vacuum water cup? Is that so? Before answering this question, let’s first take a look at how some well-known e-commerce platforms promote the effect of water cups and thermos cups.

Double-layered glass water cups are thermos cups. When purchasing glass water cups, have you ever seen that many brands and merchants display their own glass water cups? Especially when displaying double-layered glass water cups, they can add the thermal insulation function. Are double-walled glass water bottles insulated?

Double-layer plastic water cups are thermos cups. In addition to the emphasis on the heat preservation function of double-layer glass water cups, some merchants will also talk about the heat preservation function of the water cups when selling double-layer plastic water cups. So is a double-layered water cup a thermos cup?

The definition of a thermos cup has strict requirements whether it is the market, the industry or the national standard. There are strict requirements for the insulation time for different capacities, different mouth sizes and cup lid methods. Anything shorter than this time is an unqualified thermos cup.

Whether it is a double-layered glass water cup or a double-layered plastic water cup, the thermal insulation emphasized by the merchants only slows down the temperature drop for a short period of time, which is far from meeting the requirements of the insulation time.

Some “smart” merchants only talk about heat preservation, but they never talk about the length of heat preservation. Double-layer glass water cups and double-layer plastic water cups can slow down the heat conduction and cannot achieve the effect of heat preservation, so double-layer glass water cups and double-layer plastic water cups Not a thermos cup.

Friends, please note that we are talking about a double-layered glass water cup that is not a thermos cup, but it does not mean that a glass water cup cannot be used as a thermos cup. Friends born in the 80s and 70s who have used traditional glass thermos cups and kettles should know that through the vacuuming process The coated glass bladder has a strong thermos cup function, so the glass water cup that has undergone these processes can also function as a long-term heat preservation cup. Such a glass water cup can also be called a thermos cup. #Thermos cup

Seeing this, we have answered half of the title question. Since specially processed glass water cups can be insulated cups, then insulated cups are not just double-layer stainless steel vacuumed water cups, they also meet food grade requirements. Other metal water cups that can be vacuumed after welding are also insulated cups.

For example, food-grade alloys, metal titanium, etc. can be used as materials for making thermos cups. Naturally, water cups produced according to the insulation process are also thermos cups.
