Attention and requirements

● the color of the tea may change if the tea is kept warm for a long time.
● if boiling water is added immediately after boiling, the pressure in the bottle may increase and it may be difficult to open the lid. When holding the main unit vertically, slowly release the lid stopper to release the internal pressure, and then close it again.


Do not let the hot water bottle touch the cigarette holder. This may cause the body to tip over, or may cause scratching or deformation of the base.

When adding large pieces of ice, do not crush them into small pieces.
If the product is placed in a place with direct sunlight or high temperature in the car, the heat insulation effect may be reduced.

Please pay attention to the following points when carrying.

*Make sure that the backing plate is installed correctly and that the cover is securely closed. In addition, turn the engine upside down to check that there is no leakage.

*When placing it in a bag, etc., place the body vertically to prevent leakage.

*Don't make a strong impact. Even if locked, the lid will vibrate open, causing burns and other stains.


Don't put the drink in it for a long time. (this decay will cause the gas to rise and the internal pressure to rise, which may cause the cover to fly or blow out drinks, etc., which may cause personal injury or contaminate other things.)

Please be sure to protect it

Subject. erect. If placed on the side, it may cause leakage.

In addition, avoid using it in unstable conditions or places.


Keep out of the reach of children. In addition, please pay attention to pranks.

Do not tilt or close to the face to open the cover.

(if you put a hot drink in it, the internal pressure will rise, and the drink will suddenly emit or disperse, causing burns.)

Do not use for other purposes except keeping the drink warm.

Keep away from the stove and the stove. (this may cause deformation or discoloration.)

Do not place the following items.

*Dry ice, carbonated drinks (the internal pressure may rise, the plug will not open, and the drinks will blow out.)

Please do not fall, impact or strong impact. The impact will cause vacuum leakage, which may reduce the insulation effect (cold holding force).

Do not disassemble, refit or repair. (this can lead to accidents or malfunctions.

● make sure the cover plug sub unit is closed. (may cause leakage.)

● make sure the liners are properly and firmly attached. (may cause leakage.)

Make sure the amount of drink is as shown in the figure.

(if you put too much, the drink may overflow when the cap is closed, or it may leak and contaminate other things during use.)


*Please read the manual before use.
