Introduction to Components of Insulated Cups
1. Cup lid The cup lid is an important component of a thermos cup, which plays a role in preventing leakage and maintaining temperature. Common cup lids include screw caps and button caps, which are mostly made of food grade silicone and PP. Screw caps are not prone to water leakage, but opening and closing […]
How to check if stainless steel is food grade?
1. Basic methods for detecting food grade stainless steel To check whether stainless steel is food grade, the following steps can be taken: (1) Magnetic testing: Most stainless steels have magnetism, but food grade stainless steels are usually non-magnetic. A magnetic tester can be used to detect the magnetism of stainless steel. (2) Observing surface […]
Thermal insulation strategy for thermos cups
1. Ways of heat dissipation The main ways of heat loss are heat conduction, heat radiation, and heat convection. Thermal conduction refers to the transfer of heat from a high-temperature substance to a low-temperature substance through a medium. Thermal radiation is electromagnetic wave radiation caused by heat, which transfers energy to the outside world in […]
The origin of thermos cups and daily life
Thermos, also known as hot water bottle, is a masterpiece of British scientist Duval, but it was named by German glassmaker Reinhold Berg. The design of the thermos bottle is clever, with a vacuum between the inner and outer walls. Without air, heat cannot be transferred in the vacuum, so the liquid in the bottle […]

Identification method for thermos cups
1. Identification of insulation properties of the inner liner This is the main technical indicator of a thermos cup. After filling it with boiling water, tighten the bottle stopper or lid clockwise. After 2-3 minutes, touch the outer surface and lower part of the cup body with your hand. If you find obvious warmth on […]
