Inspection of inner liner insulation properties – This is a key technical parameter for thermoses. After filling with boiling water, tighten the cap or lid clockwise and wait for 2–3 minutes. Then touch the exterior and lower part of the cup. If a noticeable warm sensation is felt on the cup body and its upper surface, it indicates that the inner liner has lost its vacuum, and the insulation effect will not be optimal.
Assessment of environmental safety of accessories – The environmental safety of plastic accessories is also a matter of concern. It can be determined by smell. If the cup is made of food-grade plastic, it will have a mild odor, a shiny surface, no burrs, and a long service life with minimal aging. In contrast, ordinary or recycled plastics will have a strong odor, a dull color, many burrs, and are prone to aging and breaking.
