XIAMEN, CHINA – A major breakthrough in precision manufacturing for the maternal and child industry was announced today as Thyseed Children’s Thermos officially received the certificate for “Kid’s Vacuum Bottle with the Highest Thermal Insulation” from the World Record Certification Limited (WRCA). This historic achievement, recognized at the World Record Certification Exhibition Hall of the Xiamen International Conference and Exhibition Center, sets a new global standard for the product category.
Thyseed dominated the global performance competition for children’s thermoses by achieving an ultra-long heat retention duration of 11.6 hours.
Verified by authoritative laboratory tests, the thermos was able to maintain 55°C water at 40°C—the optimal drinking temperature for children—for nearly half a day. This time dramatically surpasses similar products on the market, which typically retain heat for only four to six hours, effectively solving the common parental frustration of “water turning cold in half a day.”
This record-breaking performance is attributed to Thyseed’s proprietary “Four-Dimensional Heat Retention System,” an integrated approach to thermal engineering:
Double-Layer Vacuum: Blocks over 90% of heat conduction, creating a “constant temperature barrier.”
Patented Heat Retention Ring: Precisely controls heat dissipation at the cup mouth, allowing 95°C water to remain at 73.2°C after six hours—far exceeding national standards (44°C).
316L Stainless Steel Inner Liner: The food-grade, seamless inner liner eliminates “heat leaks” and offers three times the corrosion resistance of standard 304 stainless steel.
Full-Dimensional Sealing Gasket: Completely blocks air convection, extending retention time.
WRCA certification officer Maxim commented that the achievement reflects both deep insight into the needs of mothers and children and the innovative strength of Chinese brands in precision manufacturing.
Beyond insulation, Thyseed emphasized safety and user experience:
Medical-Grade Materials: The inner liner uses medical-grade 316L stainless steel, safe for juice and milk.
Child-Friendly Components: The straw is made of soft Wacker (Germany) liquid silicone, and cup lid components use Total (France) food-grade PP material (BPA-free). All materials have passed 32 international safety tests and comply with EU standards.
Optimized for Age: Designs include gravity ball straws for babies and a “one-click lid opening” for school-age children, focusing on ease of use and safety.
Zhao Qingtai, Director of WRCA China Application Center, stated, “With its 11.6-hour heat retention data, Thyseed has set a new global standard for children’s thermoses. This pursuit of ultimate quality is worthy of the entire industry’s learning.”
