Usage Method:
1. Before using for the first time, the inner pot should be thoroughly cleaned.

2. First wash the inner cavity with a small amount of hot or cold water (do not use steel wool for cleaning), then drain it, and then refill with boiling water or cold water to ensure that the insulation effect is good.
3. After each use, please clean it thoroughly and keep it dry.
4. It is not recommended to store carbonated beverages in cups for a long time to extend the service life of vacuum flasks.
5. Do not approach heat sources, and do not subject to violent impact.
6. Keep it out of the reach of children to prevent scalding.

Knowledge of Insulated Cups

1. Simple Identification Method for Vacuum Insulation Performance: Pour boiling water into the vacuum cup and tightly twist the lid or cover clockwise for 2-3 minutes. Then, touch the outer surface of the cup with your hand.

 If the cup body has obvious warm phenomena, it indicates that the product has lost vacuum, and cannot achieve good insulation effect.

2. Seal Performance Identification Method: After adding water to the cup, tighten the bottle cap and cup cover in a clockwise direction, place the cup flat on the table, and there should be no water leakage;

 The lid of the cup should be tightly fitted to the cup mouth with no space.

3. Plastic Parts Identification Method: The characteristics of food-grade new plastic are small odor, shiny surface, no burrs, long service life and less prone to aging.

 The characteristics of ordinary plastic or recycled plastic are strong odor, dull color, many burrs, and the plastic is prone to aging and easy to break.

4. Capacity Identification Method: The depth of the inner pot is essentially the same as the height of the outer shell (a difference of 16-18MM), which corresponds to the nominal capacity.

 Some inferior vacuum flasks may add sand or cement blocks to compensate for the missing weight. Misconception: A heavier cup (pot) does not necessarily mean it is better.

5. Simple Identification Method for Stainless Steel Materials: There are many specifications for stainless steel materials, among which 18/8 indicates that this stainless steel material contains 18% chromium and 8% nickel.

Materials that meet this standard comply with national food-grade standards and are environmentally friendly green products. They are resistant to rust and corrosion. The 304 material is imported steel.

Never rusts; 201 steel produced domestically is also relatively rust-resistant, but its insulation performance after being made into products is not as good as that of 304 steel.
