Cold cup and thermos may sound similar, but in fact, they each have their own unique ideas! Today, let’s talk about them and make it easy for you to choose cups.
1. Differences in material and structure
Insulated cups are usually made of stainless steel or titanium and have a vacuum insulation layer inside, while plastic cups and glass cups do not have insulation effect.
Cold proof cups are generally made of ceramic or stainless steel, with a lid on the top for better sealing, which can effectively lock in the temperature of cold drinks.
The bottom of the thermos may have the words “Hot matters” and “Clod matters”, indicating that it has a dual effect of hot and cold.
2. Principles of insulation and cooling
The thermos cup is insulated with a vacuum insulation layer to prevent heat transfer, and the interlayer is plated with copper or silver to reflect heat radiation and keep the beverage at a certain temperature.
The cooling cup also has a vacuum insulation layer and a silver layer to prevent external heat from entering and maintain the cold state of the cold drink.
The double-layer structure of the thermos cup can also avoid heat convection, further locking in temperature, and performs well in both heat and cold insulation.
3. Usage scenarios and precautions
Insulated cups can also be used for cooling in summer, but it should be noted that their cooling effect may not be as good as specialized cooling cups.
Cold cup is not suitable for keeping hot water warm for a long time, as it is prone to burns. When choosing, be sure to read the instruction manual carefully.
When choosing a thermos, the material of the inner liner is very important. It is recommended to choose 304 or 316 stainless steel and regularly check for water leakage to ensure safe use.
