Before sharing with you, let me make some environment settings first. Friends, it is best to identify the newly purchased thermos cup at home, because it will be more convenient to operate at home.
First of all, how do we identify whether the thermos cup is insulated? After getting the newly purchased thermos cup, friends should first open the water cup and take out the desiccant and other accessories contained in the inner tank, then pour boiling water into the cup, tighten (cover tightly) the cup lid, and then put the lid on tightly. Let it sit for 1 minute, then touch the outer wall of the thermos cup with your hand. If you find that the outer wall of the thermos cup is obviously hot, it means that this thermos cup is not insulated. If the temperature of the outer wall does not change from the temperature before pouring hot water, it means that this water cup is not insulated. There is no problem with the functionality.
After the thermal insulation test, we will start to test the sealing effect of the water cup. Tighten the lid of the cup and fill the thermos cup with water and place it upside down. Please be sure to place it in a safe place. Do not fall due to unstable inversion and cause heat. Water overflows. After inverting it for 15 minutes, we check whether there is any water overflowing from the sealing position of the water cup. If there is no overflow, it means that the sealing effect of this water cup is qualified.
