The thermos cup, as an indispensable item in modern life, has long been deeply rooted in the hearts of the people.
However, the dazzling array of thermos cup brands and various products on the market can make people feel overwhelmed.
The news once exposed a news about a thermos cup. The thermos cup that was originally suitable for drinking hot water actually exploded with water containing toxic substances and became a life-threatening cup.
The reason is that some unscrupulous businesses use scrap metal to make thermos cups, resulting in heavy metals in the water seriously exceeding the standard, and long-term drinking can cause cancer.
So how to judge the quality of the thermos cup? Here are some methods:
1. Pour strong tea into a thermos cup and let it sit for 72 hours. If the cup wall is found to be severely discolored or corroded, it means the product is unqualified.
2. When purchasing a cup, be sure to check whether it is marked 304 or 316 on the bottom. Commonly used stainless steel materials for thermos cups are generally divided into 201, 304 and 316.
201 is usually used for a wide range of industrial purposes, but it can easily lead to excessive metal precipitation and lead to heavy metal poisoning.
304 is internationally recognized as a food-grade material.
316 has reached medical grade standards and has stronger corrosion resistance, but of course the price is higher.
304 stainless steel is the lowest standard for drinking cups or kettles in our lives.
However, many stainless steel cups on the market are marked as 304 material, but in fact most of them are fake and inferior 201 material faked by unscrupulous manufacturers. As consumers, we must learn to identify and take precautions.
3. Pay attention to the accessories of the thermos cup, such as lids, coasters and straws. Be sure to choose food-grade PP plastic or edible silicone.
Therefore, choosing a thermos cup is not only about weight or good appearance, but also requires skills.
Buying the wrong thermos cup means ingesting toxins, so choose carefully.
How to choose the right thermos cup?
1. Materials and safety
When choosing a thermos cup, we must consider whether its material is safe and durable.
Some low-quality plastic cups may release harmful substances and pose potential threats to our health. They have long-lasting heat preservation time, are durable and are easy to clean.
2. Long-lasting heat preservation time
The biggest function of a thermos cup is to keep warm, and the time of keeping it warm is also very important. A high-quality thermos cup can effectively keep the temperature of the drink for several hours.
