The quality of thermoflask water bottle on the market are varies. How can we identify them? Industry guys will suggest that we should focus on the thermal insulation performance of the inner tank structure, the degree of sealing between the lid and the bottle body, and whether the material releases harmful substances etc..
Way 1. This is the main technical index of the stainless steel cups. After filling with boiling water, tighten the bottle cover. 2 to 3 minutes later, touching the outer surface and lower part of the cup body with your hands, if the body and the upper part of the cup have obvious warming phenomenon, it means that it cannot achieve a good heat preservation effect
Way 2. To identify the sealing performance. Filling a glass of water in this thermos cup for 5 minutes, then screwing the lid tightly. We put the cup flat on the table, or shake it a few times, if there is no leakage, it means the sealing performance is good.
Way 3. We should check if the lid and the mouth of the cup are screwed together flexibly, or if there is a gap
Way 4. We can be identified by smell. If the cup is made of food-grade plastic, the smell is small, the surface is bright, there is no burr, and we can use more long time. Ordinary plastic or recycled plastic has a strong odor, dark color, many burrs, and the plastic is easy to age and break.
