How can I buy high-quality vacuum insulated cups?








1. Simple identification method for vacuum insulation performance: Pour boiling water into the insulation cup and tighten the bottle stopper or lid clockwise for 2-3 minutes. Touch the outer surface of the cup body with your hand. If there is obvious warming phenomenon on the cup body, it indicates that the product has lost its vacuum degree and cannot achieve good insulation effect.
2. Sealing performance identification method: After adding water to the cup, tighten the bottle stopper and lid in a clockwise direction, and place the cup flat on the table, ensuring there is no water leakage; The rotation of the cup cover and cup mouth should be flexible and without gaps.
3. Plastic parts identification method: The characteristics of 304 new plastic are small odor, bright surface, no burrs, long service life, and not easy to age. The characteristics of ordinary plastic or recycled plastic are strong odor, dark color, multiple burrs, and easy aging and fracture of plastic.


4. Simple capacity identification method: The depth of the inner liner is basically consistent with the height of the outer shell, and the capacity is consistent with the nominal value (with a difference of 16-18MM). Some poor quality insulation cups add sand and cement blocks to the cup to make up for the missing weight. Myth: A heavier cup (kettle) may not necessarily be good.
5. Simple identification method for stainless steel materials: There are many specifications for stainless steel materials, among which 18/8 indicates that this stainless steel material contains 18% chromium and 8% nickel. Materials that meet this standard and meet the national 304 standard are green and environmentally friendly products, with rust and corrosion resistance. The color of the ordinary stainless steel cup body appears white and dark. If it is soaked in 1% saline solution for 24 hours, rust spots will appear, and some of the elements contained in it exceed the standard, directly endangering human health.
