How to distinguish the authenticity of Tiger brand children's thermos cup?
1. Simple identification method of thermal insulation performance: pour boiling water into a thermos cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the outer surface of the cup by hand. If the temperature of the cup is obviously increased, especially if the lower part of the cup is heated, it means that the product has lost its vacuum degree and can't achieve good insulation effect, but the lower part of the thermos cup is always cold. Myth: Some people use their ears to determine whether there is a hissing sound, but they can't hear whether it is a vacuum.
2, cup appearance identification method. Look at whether the surface polishing of the inner container and the outer container is uniform and consistent, and whether there are bumps and scratches; Second, see if the welding of the mouth is smooth and consistent, which is related to whether you feel comfortable when drinking water; Third, check whether the internal seal is tight and whether the plug and the cup match; Look at the mouth of the cup, the rounder the better.
3. Check the labels and other accessories of the cups. See if the product name, capacity, caliber, manufacturer's name and address, adopted standard number, usage method and precautions are indicated. Tiger brand thermos cup has tiger brand logo.
Simple identification method of vacuum insulation performance: pour boiling water into a thermos cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the outer surface of the cup with your hands. If there is obvious temperature rise in the cup, it means that the product has lost its vacuum degree and cannot achieve good heat preservation effect.
4. Sealing identification method: After the cup is filled with water, tighten the cork and the cup cover clockwise, and put the cup flat on the table, so there should be no water leakage; The rotation of the lid and the mouth of the cup should be flexible and there should be no gap.
5. Identification method of plastic parts: Food-grade new plastics are characterized by small smell, bright surface, no burr, long service life and difficult aging. Ordinary plastics or recycled plastics are characterized by strong smell, dark color, many burrs and easy aging and fracture.
6. Simple capacity identification method: the depth of the inner tank is basically consistent with the height of the outer shell, and the capacity (phase difference 16- 18MM) is in line with the nominal value. Some poor quality thermos cups will add sand and cement blocks to make up for the missing weight. Myth: The weight of a cup (pot) is not necessarily good.
The above is the introduction of the identification method of Tiger brand children's thermos cups, which is very important when purchasing Tiger brand children's thermos cups. When the weather is cold, bring a thermos cup to your child, which can make the water temperature drop slowly and prevent the child from drinking cold water in cold weather. As we all know, a good thermos can keep warm for a long time, and naturally it is expected to buy a good quality thermos. In addition, a thermos cup with poor heat preservation will affect its use.
