First, how long does the children's thermos cup usually keep warm?
According to the test requirements, the children's thermos cup is filled with 95-degree hot water when the room temperature is above 20 degrees, and the temperature of the hot water in the thermos cup is tested after 6 hours without opening the bottle cap. 12 hours!
This is a universal standard. Generally, the insulation effect of children's thermos cup can reach 6-8 hours, but the insulation time will be shorter if it is a straw kettle. If you take your baby out to play during the day, the general children's thermos cup can fully meet the needs.

Second, what should I do if my child's thermos cup is not insulated?
Thermal insulation is to minimize the loss of heat. After the children's thermos cup is not insulated, the lid and bottle mouth should be wiped first to wipe off the impurities and dust deposited on the bottle mouth, which is more convenient for later operation and maintenance. Then wrap the tape around the bottle mouth. Note that the trick here is to narrow the gap after winding the children's thermos cup once. The smaller the gap, the less likely it is that the thermos cup will dissipate heat. After the children's thermos cup is firmly wound, cut off the remaining adhesive tape with scissors, and then stick one end of the adhesive tape on the cup wall of the children's thermos cup to ensure that it will not fall off when the lid is opened.
Third, children's thermos cup purchase skills
1. Simple identification method of vacuum insulation performance: pour boiling water into a children's thermos cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the outer surface of the cup by hand. 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. Vacuum thermos cups are more suitable for 1-3-year-old babies, especially for 1 year-old babies.
2. Sealing appraisal method: After adding water to the children's thermos cup, tighten the cork and lid clockwise, and put the thermos cup flat on the table, without water leakage; The rotation of the lid and the mouth of the cup should be flexible and there should be no gap.
3. 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.
4. 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.
