What are the pictures of thermos cups? I believe everyone has used them. Thermos cups are leak-proof, collision-proof and fall-proof. Of course, there are many pictures of thermos cups. Let me take a look at the relevant information of thermos cups with you.

1 Before use, clean the inside and outside of the cup (cover) with neutral detergent in warm water.

In order to keep the cup (pot) warm and cold, it is suggested to add hot water or ice water for preheating or precooling. It will be better if ice cubes are added when keeping cold.

To prevent leakage, please tighten the switch and the lid clockwise when the cup is tilted.

2, use to avoid falling, collision or strong impact, which will cause the deformation of the cup and affect the efficacy of the product.

Accessories such as heat preservation switch and cup cover are made of food-grade plastics according to national standards. Please do not lose accessories such as switch, cup cover and washer during use, so as not to affect normal use.

Avoid any form of direct heating or high temperature, otherwise it will cause resin deformation and discoloration, which will affect the use efficiency of the product.

Do not add dry ice, carbonated drinks and other liquids that are prone to high pressure, and do not add liquids containing salt such as soy sauce and soup to avoid corrosion of the cup.

When cleaning, please use warm water with neutral detergent, and do not use alkaline bleach, chemical rags and other cleaning agents.

After filling milk and other perishable beverages, please drink them as soon as possible and clean them to avoid rotting the liner after deterioration.

Do not use it for other purposes except heat preservation and cold preservation.

3. When it is not used for a long time, the inner container should be fully kept dry.

In order to prevent odor or stains, clean it after use and make it fully dry.

Because the use of impure water will leave red spots similar to rust, it can be soaked in warm water and diluted vinegar for 30 minutes and fully cleaned.

Cup lid: Do not sterilize at high temperature to avoid deformation. After cleaning, make sure that the sealing ring is installed properly.

Wipe: after opening the lid of the thermos cup, wipe the bottle mouth of the thermos cup with toilet paper to wipe off the impurities and dust deposited on the bottle mouth, which is more convenient for subsequent operation and repair.

After winding and wiping the bottle mouth of the thermos cup, wrap it around the bottle mouth with adhesive tape. Note that the trick here is to wrap it tightly. The smaller the gap, the smaller the possibility of heat dissipation of the thermos cup.

Check, after the thermos cup is firmly wound, cut off the remaining adhesive tape with scissors and stick it on the cup wall with the tail end of the adhesive tape to ensure that it will not fall off when the lid is opened.

The development origin of thermos cup

1892, Sir james duval, a Scotsman from Oxford University, invented the vacuum thermos. He put one bottle into another bottle, and then pumped the air out of the gap between the two bottles. Because vacuum does not transfer heat, the hot water or cold water in the thermos cup will keep its original temperature for a long time. By the 1950s, the sales of thermos cups reached its peak, and family picnics, seaside hiking and camping in this period all carried thermos cups.

After the thermos cup is hit hard, there may be a crack between the shell and the vacuum layer, and the air will enter the interlayer after the crack, so the thermal insulation performance of the thermos cup will be destroyed. This is normal, no matter what kind of cups, their principle is the same, that is, the air in the middle is pumped out with double stainless steel to reach a certain degree of vacuum. Make the heat of the water inside pass out as slowly as possible. This process is related to the process and the vacuum degree of pumping. The process is good or bad, which determines the length of time to make your heat preservation worse. In addition, your thermos cup will not keep warm when it is used, because the vacuum layer leaks air and forms convection in the interlayer, which will not be able to isolate the inside and outside.

1, open the lid of the thermos cup, and then wipe it on the bottle mouth with a paper towel.

2. After wiping, prepare a roll of adhesive tape and wrap it around the mouth of the thermos cup.

3. Prepare scissors after winding and cut the tape with scissors.

4. Pour hot water into it and cover the bottle cap, then turn the thermos cup upside down.

5. Wrap a roll of adhesive tape around the bottle mouth of the thermos cup, which is equivalent to installing a sealing strip around the bottle mouth of the thermos cup. The effect is very good.

Matters needing attention in the use of thermos cup

1, before use, you can unpack it, and then blanch it with boiling water or detergent for several times for high-temperature disinfection.

2, the water should not be too full, to avoid hot water burns.

3. Don't hold carbonated drinks such as milk, dairy products and juice for a long time;

4. When cleaning, you can use a soft cloth and a detergent diluted with warm water, and you can't use alkaline bleach. In addition, in order to prevent odor or stains, please clean it after use to make it fully dry. These are the common methods of using thermos cups, and you can do better if you pay more attention.
