Nandu News Reporter Yang Liyun The temperature dropped sharply, and winter began overnight. Have you bought a thermos cup that is essential for autumn and winter? Recently, the Shenzhen Longhua District Consumer Committee commissioned the Shenzhen Quality Consumption Research Institute to conduct a comparative experiment of 18 children's thermos cups.
results show that the chemical safety indicators and physical safety performance tested by 18 children's thermos cups all comply with national mandatory standards. However, a twinbell brand vacuum insulation pot has insulation performance, impact resistance and labeling that do not meet the relevant requirements of GB/T 29606-2013 "Stainless Steel Vacuum Cup". Is the thermal insulation pot of
children up to standard?
Samples: 18 samples include 4 thermos cups with straws and 14 thermos cups with double-covers (straw cover + direct drink cover), involving 18 domestic and foreign brands: Cuipo, Babycare, Face, Twinbell, Tiger Brand, Elephant Imprint, Thermos, Cup Bear, Locke, Disney , Fisher, Supor, NetEase Yanxuan, Longshida, Fuguang, Daka, Jiaqi, and Hals.
Item: The amount of heavy metal dissolution of metal inner liner, the total migration of nozzle, straw, sealing components and inner liner coating, and the consumption of potassium permanganate , the sealing cover (plug) and hot water odor, strap and suspender strength, impact resistance, label identification.
standard: food contact material GB 4806 series standard, national recommended standard , infant and children's textile product standards.
twinbell brand vacuum insulation pot
thermal insulation performance does not meet the standard requirements
0 The results of this comparison test show that all the chemical safety indicators inspected by 18 children's thermos cups meet the national mandatory standards. Including the amount of heavy metal dissolution of metal inner liner, the total migration of nozzles, straws, sealing components and inner liner coatings, and the consumption of potassium permanganate are all in line with the limit requirements of the national mandatory standards. In terms of physical safety performance, 18 children's thermos harnesses, suspenders, and other drinking accessories also meet the standard requirements.
However, in terms of performance, one model failed to meet the standard requirements. The insulation performance is one of the important functions of the thermos cup. The quality of the insulation performance is closely related to the production process, vacuum layer evacuation technology and sealing properties, and is also related to the capacity of the container, whether there is an inner plug, diameter, and the sealing result of the cup lid.
results show that according to the relevant standards of GB/T 29606-2013 "Stainless Steel Vacuum Cup" 6 hours after testing, 18 children's thermos cups with straws meet the standard requirements, and the temperature of children's thermos cups with the best insulation effect can be maintained above 70℃. However, after 24 hours of testing, the water temperature of twinbell brand vacuum insulation pot (direct drinking lid) was 32.2℃ and did not meet the standard requirements (≥37℃). After 6 hours of testing, 18 children's thermos cups with straws meet the standard requirements.
After 24 hours of testing, the twinbell brand vacuum insulation pot (direct drinking lid) had a water temperature of 32.2℃ and did not meet the standard requirements (≥37℃).

impact resistance does not meet the standard
In addition, in terms of usage performance, the sealing cover (plug) of 18 children's thermos cups and the strength of hot water odor, straps and suspenders all meet the standard requirements. However, in terms of impact resistance, there is one thermos that does not meet the relevant requirements.
Impact resistance means that after the product is subjected to falling impact and sway impact test, the product should be free of water leakage, cracks and damage, and the insulation performance still needs to meet the corresponding requirements. The impact resistance of this children's thermos cup is tested with reference to the national recommended standard GB/T 29606-2013 "Stainless Steel Vacuum Cup". Among the 18 children's thermos cups, only 1 twinbell vacuum thermos pot does not meet the relevant requirements.

specifications are not marked Nominal capacity
tag identification generally includes product production and manufacturing information, material information, warning instructions, etc., and convey to consumers how to correctly and safely use the product functions, basic performance, characteristics and other information related to it, which is of great significance to guide consumers to purchase. According to the requirements of national mandatory standards, product identification information should be clear and true and should not mislead consumers. The product should provide sufficient product information, including labels, instructions and other identification contents and product qualification certificates. The results show that 18 samples meet the requirements of national mandatory standards.
On this basis, according to the requirements of GB/T 29606-2013 "Stainless Steel Vacuum Cup", the product should be marked with nominal capacity, stainless steel material type, insulation performance, standard number and name of execution, instructions for use and precautions, etc. Among the 18 children's thermos cups this time, the product specifications of twinbell vacuum thermos are not marked with the nominal capacity.
Children's thermos cup with straw
should not be filled with hot water
How do consumers choose children's thermos pots? The Shenzhen Longhua District Consumer Committee recommends that the temperature of liquid storage cups with straws should not be too high, and it is best to be below 50℃. To prevent accidental ingestion and hot water splashing and scalding. At the same time, you can choose a thermos with a slow-open cup lid design or a child safety lock to prevent children from accidentally opening it and causing scalding.
In addition, it is recommended not to use a thermos cup to hold other beverages unless otherwise specified by the company. Before using stainless steel thermos, consumers should carefully read the instructions for use. They must be scalded with boiling water for the first time and disinfected at high temperatures. At the same time, avoid acidic beverages (such as carbonated beverages, etc.) and dairy products (such as milk) in the thermos cup to avoid corrosion of the inner wall of the thermos cup and the rapid reproduction of microorganisms affects children's health.
