Usage:
1. Wash the inner bladder thoroughly before the first use. 

2. Wash the tank with a small amount of hot water or ice water first (do not use steel wire ball to clean) and then pour Drop and refill boiled or iced water to ensure good insulation. 
3. After each use, please clean and keep dry.
4. Do not store carbonic acid beverage in the cup for a long time to extend the service life of the thermos cup. 
5, do not approach the heat source, not violent impact. 
6. Keep out of reach of children to avoid scald.

Knowledge about vacuum cup

1. Simple identification method of vacuum insulation performance: Pour boiling water into the vacuum flask and tighten the cork or lid clockwise for 2-3 minutes before touching the outer surface of the cup with your hand.

 If the cup body has obvious temperature phenomenon, it means that the product has lost the vacuum degree and cannot achieve good thermal insulation effect.

2. Identification method of sealing performance: After the cup is filled with water, tighten the cork and lid clockwise and place the cup flat on the table. There should be no water leakage.

 The lid and the mouth of the cup should be flexible, no gap.

3, plastic accessories identification method: food grade new plastic is characterized by small smell, bright surface, no burr, long service life is not easy to aging.

 Common plastic or recycled plastic is characterized by big smell, dark color, burr, plastic easy to aging easy to break.

4. Simple capacity identification method: the depth of the tank is basically the same as the height of the shell, and the capacity is consistent with the nominal value (the difference is 16-18mm).

 Some poor quality thermos cups add sand and cement blocks to make up for the missing weight. A heavier cup or pot is not always a better cup or pot.

5. Simple identification method of stainless steel materials: there are many specifications of stainless steel materials, among which 18/8 means that the components of the stainless steel materials contain 18% chromium and 8% nickel.

The material that meets this standard, accord with national food grade standard is green environmental protection product, product is rust-proof, corrosion-resistant. 304 is made of imported steel,

Never rust; 201 For domestic steel products, it is not likely to rust, but after being made into products insulation performance is not as good as 304.
