How to distinguish the true and false Tiger brand thermos cups?

1, a simple appraisal method of vacuum insulation performance. First, pour boiling water into the Tiger brand thermos cup, tighten the cork or lid clockwise for 2 to 3 minutes, and then touch the outer surface of the cup with your hands. If the cup is obviously warm, it means that the product has lost its vacuum degree and can't achieve good heat preservation effect, so this Tiger brand thermos cup is a fake and shoddy product.

2, sealing performance appraisal method. After adding water to the Tiger mug, tighten the cork or lid clockwise and lay the Tiger mug flat on the table. There should be no water oozing out. The lid and the mouth of the cup can rotate flexibly and seamlessly.

3. Identification method of plastic parts. Tiger brand thermos cup is made of new food-grade plastic, which is characterized by small smell, bright surface, no burr, long service life and not easy to age. Ordinary plastics or recycled plastics are characterized by strong smell, deep color, many burrs and easy aging and fracture. Therefore, when identifying the true and false Tiger brand thermos cup, we can see whether the plastic of the thermos cup has an odor.

Extended data:

Almost every thermos cup has its own unique characteristics, and some have double cover design. When driving, just press the little red button in the middle, and the water will automatically flow out without splashing on the car. Some have a tea partition in the middle of the thermos cup, which can quickly filter tea and tea, which is very suitable for office white-collar workers.

There is also a double-cup design, and the bottom box cover also has a hidden compartment, which can hold tea, sugar and coffee. The vacuum liner made of stainless steel double-layer can not only release water, but also put ice water. Some cups also have the function of stewing, and the thermos cup with the least function has at least two functions.

Maintenance method:

Avoid collision and collision during use, so as not to damage the cup or plastic, resulting in insulation failure or water leakage. Tighten the plug with proper force, not too hard to avoid thread failure.

When drinking coffee, tea or drinks frequently, the inner container will change color. This is a normal phenomenon and can be removed with a toothpaste toothbrush.
