First look at the glass. A look at the internal and external surface polishing is uniform, whether there are scratches and scratch defects;
Second see whether the mouth welding is smooth and consistent, this relationship with a drink when the feeling is comfortable;
Three see the quality of plastic parts. Not only will affect the service life, but also affect the health of drinking water;
Four see whether the internal seal is tight. Whether the screw Plug and cup body fit properly. Whether the spin is free or not is leaking. Fill a glass of water inverted four, five minutes or a few hard to shake off to verify whether the leak. Then look at the insulation performance, this is the main technical indicators of the thermos. General purchase can not be in accordance with the standard inspection, but may be filled with hot water after the feel of the cup is not warm two minutes after the hot water cup body will be hot, and the lower part of the cup is always cool.
There are several ways to do this:
1, the vacuum insulation performance Simple identification method: The boiling water into the Thermos cup with a clockwise screw or cup cover 2-3 minutes after the hand touch the outside surface, if the cup body has a clear warm phenomenon, the product has lost the vacuum, can not achieve good thermal insulation effect.
2, Sealing performance Identification method: After the cup with water, in the clockwise direction to tighten the cork and cup cover, the Cup flat on the table, should be without water leakage, the cup lid and cup mouth of the rotation should be flexible, there is no gap.
3, Plastic parts identification method: Food-grade new plastics are characterized by small smell, bright surface, no burr, long life is not easy to aging. Ordinary plastic or recycled plastic is characterized by large odor, dark color, burr, plastic easily aging and easy to break.
4, the capacity of simple identification method: The depth of the liner and the height of the shell is basically consistent, (16-18mm) capacity and nominal value in accordance with. Some of the poorer cups add sand and cement to the cup to compensate for the missing weight. Myth: The heavier the cup (pot) is not necessarily good.
5, stainless Steel Simple identification method: Stainless steel material specifications, of which 18/8 of the stainless steel material contains 18% chromium, containing 8% nickel, to meet this standard of materials, in line with the national food-grade standards are green environmental products, products rust-proof, corrosion-resistant. Ordinary stainless steel cup body color appears whitish and dark, if the concentration of 1% brine immersion in 24 hours will produce rust, the part of the elements contained in excess, directly endanger the health of the human body.
