Usage
Minors should use it under the guidance or notification of an adult. Before use, please clean the inside and outside of the cup (kettle) with neutral detergent in warm water. To achieve the best effect of keeping the cup (pot) warm and cold, it is recommended to first add hot or cold water for preheating or pre cooling. Adding ice cubes will have a better effect when keeping it cold. To prevent leakage, please tighten the switch and lid clockwise when the cup body is tilted.
matters needing attention
1. Preheat or pre cool with a small amount of boiling water (or ice water) for 1 minute before use for better insulation and cooling effect.
2. After filling the bottle with hot or cold water, be sure to close the bottle stopper tightly to prevent water leakage and burns.
3. Excessive filling of hot or cold water may cause water leakage. Please refer to the water quantity location diagram in the manual.
4. Please do not place it near a fire source to avoid deformation.
5. Please do not place it within the reach of young children and be careful not to let them play as there is a risk of burns.
6. Be careful not to scald when placing hot drinks in the cup.
7. Please do not include the following beverages: dry ice, carbonated drinks, saline liquids, milk, dairy beverages, etc.
8. When keeping hot tea warm for a long time, it will change color. It is recommended to use tea bags or other materials to brew it when going out.
9. Please do not put the product in the dishwasher, dryer, or microwave.
10. Prevent bottles from falling and causing significant impacts, to prevent surface dents that may lead to poor insulation and other malfunctions.
11. If the product you purchased is only suitable for cold insulation, please do not add hot water insulation to avoid burns.
12. If salt containing food and soup are loaded, please remove them within 12 hours and clean the thermos.
13. Prohibit loading the following items:
(1) Dry ice, carbonated drinks (to avoid the risk of rising internal pressure, which may cause the bottle cap to fail to open or the contents to spray out).
(2) Sour drinks such as Plum juice and lemon juice (can cause poor heat presPurchasing Tips
1、 Using magnets, method: Take two insulated cups - one with a magnet and the other without a magnet. The two insulated cups can hold water at around 80 degrees Celsius, and cover the cup tightly. After three hours, the water temperature of the thermos cup that attracted the magnet changed to 40 degrees, while the thermos cup that did not attract the magnet remained above 70 degrees. From such an experiment, it can be seen that the effect of magnetic insulated cups is not strong
2、 Using boiling water: After filling it with boiling water, tighten the bottle cap or insulated cup cap clockwise. After about 2-3 minutes, touch the outer surface and lower part of the cup with your hand. If you find a warm feeling, it indicates that the insulation performance of the insulated cup is not good enough. And can test the sealing of the insulation cup. Fill a glass of water, tighten the lid, invert for a few minutes, or shake vigorously. If there is no leakage, it indicates good sealing performance.
3、 Using accessories: Whether the accessories used are healthy and environmentally friendly. It is very important whether the plastic parts of the thermos are healthy and environmentally friendly. It can be distinguished by smell. If the thermos is made of food grade plastic, its odor will be small, the surface will be bright, there will be no burrs, the service life will be long, and it is not easy to age; If it is ordinary plastic, it will be inferior to food grade plastic in all aspects.
Maintenance methods
1. Before use, clean the inside and outside of the cup (lid) with neutral detergent in warm water.
To achieve the best effect of keeping the cup (pot) warm and cold, it is recommended to first add hot water or ice water for preheating or pre cooling. Adding ice cubes will have a better effect when keeping it cold.
To prevent leakage, please tighten the switch and lid clockwise when the cup body is tilted.
2. Use to avoid dropping, colliding, or strong impact, which may cause deformation of the cup body and affect the product's effectiveness.
Insulation switches, cup covers, and other accessories are made of food grade plastic according to national standards. Do not lose switches, cup covers, washers, and other accessories during use to avoid affecting normal use.
Avoid any form of direct heating or exposure to high temperatures, as it may cause resin deformation, discoloration, and affect the effectiveness of the product.
Do not add high pressure liquids such as dry ice or carbonated drinks to the vacuum cup, and do not add salt containing liquids such as soy sauce or soup to prevent corrosion of the cup body.
Please use neutral detergent and warm water for cleaning, and do not use alkaline bleach, chemical cloths, or other cleaning agents.
After adding perishable beverages such as milk, please drink them as soon as possible and clean them to avoid spoilage and rotting of the inner container.
Do not use it for any purpose other than heat and cold preservation.
3. When not in use for a long time, the inner container should be kept completely dry.
To prevent odor or stains, clean thoroughly after use and allow to dry thoroughly.
Due to the presence of rust like red spots after using impure water, it can be thoroughly cleaned by soaking in warm water and diluted vinegar for 30 minutes.
Cup lid: Do not disinfect at high temperatures to avoid deformation. After cleaning, it should be confirmed that the sealing ring is installed properly
Vacuum insulated cup for brewing tea
Some things about vacuum insulated cups
A container for holding water is usually made of stainless steel and a vacuum layer, with a lid at the top and a tight seal. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside, achieving the purpose of insulation. Vacuum cups have evolved from thermos bottles, and the principle of insulation is the same as that of thermos bottles, except that people make bottles into cups for convenience. There are three ways for heat to propagate: radiation, convection, and transfer. The silver cup liner inside the thermos can reflect the radiation of hot water, and the vacuum between the liner and the body can block the transfer of heat. Bottles that are not easy to transfer heat can prevent heat convection.
