Product Usage Instructions
1. Pre-Use Preparation
Before first use, clean the inner tank, lid and silicone ring with warm water and neutral detergent, then rinse and dry thoroughly. Do not use hard brushes or abrasive cleaners to avoid scratching the inner and outer walls, which helps maintain the product's appearance and service life.
2. Insulation Usage Method
-
For Hot Drinks: Pour a small amount of 80-90°C hot water to preheat the flask for 3-5 minutes, discard the preheating water, then fill with boiling water and tighten the lid tightly to maximize the heat retention effect.
-
For Cold Drinks: Add ice water or ice cubes to pre-cool the flask for 5-10 minutes, pour out excess water, then fill with cold beverages and seal the lid properly.
-
Do not overfill the flask with liquid; leave a small gap to avoid overflow when closing the lid and prevent internal pressure buildup.
3. Daily Cleaning & Maintenance
After each use, empty the remaining liquid and clean the flask promptly to avoid peculiar smells. Keep the lid open when storing for natural drying, and do not soak the whole flask in water for a long time. Regularly clean the silicone sealing ring to keep it clean and maintain the product's leakproof performance.
