the following identification methods can be used for stainless steel vacuum flasks:

(1) simple identification method of heat preservation performance: pour boiling water into the heat preservation cup and screw the bottle stopper or cup cover clockwise for 2-3 minutes, then touch the outer surface of the cup body by hand, if the cup (pot) has obvious warmth. in particular, the lower part of the cup is hot, indicating that the product has lost the vacuum and can not achieve a good thermal insulation effect, while the lower part of the insulated cup is always cool. misunderstanding: someone uses their ears to hear if they have a sizzling sound to determine their thermal insulation performance. the ear can't hear whether it is vacuum.

(2) sealing performance identification method: after adding water to the cup (pot), screw the bottle stopper or lid in a clockwise direction, and place the cup (pot) on the table top, and it should not leak out; the cup (pot) cover and the screwing in and out of the cup should be flexible and free of gaps. fill it with a glass of water for four or five minutes, or use a few squats to verify that it is leaking.

(3) plastic parts identification method: food-grade new plastic features: small smell, bright surface, no burr, long service life and not easy to aging. the characteristics of ordinary plastics or recycled plastics: large smell, dark color, many burrs, and easy aging of plastics. this will not only affect the service life, but also affect the sanitation of drinking water.

(4) simple capacity identification method: the depth of the inner liner is basically the same as the height of the outer casing, and the difference between the capacity and the nominal value is consistent with the nominal value. some domestic brands pay for the missing material in order to cut the weight of the material in the cup (pot). add sand and cement blocks. myth: the weight of the cup (pot) is not necessarily good.

(5) appearance identification method of the cup. look at whether the surface of the liner and the outer liner is evenly polished, whether there is any bruises or scratches; secondly, whether the mouth welding is smooth and consistent, which is related to whether the feeling of drinking water is comfortable; thirdly, whether the internal seal is tight, whether the screw plug and the cup body match; four look at the cup mouth, the more round the better.

(6) check the accessories such as the label of the cup. look for the name, capacity, caliber, manufacturer's name and site, the standard number used, the method of use, and precautions in use. a manufacturer who attaches importance to quality will strictly demonstrate the performance of its products in accordance with the relevant national standards.

customers should also pay attention to the selection of products, not only look at the appearance, but also pay attention to whether the instructions are insulation products. some of the products are now novel and generous, very similar to insulation products, but have no insulation properties. if there is a "excellent cup", the green body of the grass, exquisite shape, smooth lines, comfortable feel, the product does not deceive consumers, because its instructions clearly understand that it can be "warm hands in winter, not hot in summer" consumers have to blame their eyes.

precautions when using the thermos cup (bottle, bottle):

the thermos cup can't hold juice, milk, green tea or carbonated drinks for a long time. when using it for the first time, it needs to be thoroughly washed with a neutral detergent.

avoid collisions and impacts during use to avoid damage to the cup or plastic, resulting in insulation failure or water leakage. when tightening the screw plug, the force should be appropriate. do not over-rotate to avoid the screw bolt failure. when drinking coffee, tea or beverages regularly, the inner liner will change color. this is normal. use a toothbrush to remove the toothpaste.
