3 tips to teach you how to choose a qualified thermos cup

In recent years, as more and more people have begun to carry thermos cups with them when traveling, thermos cups are no longer just a vessel for holding water, but have gradually become a standard health accessory for contemporary people. There are many thermos cups on the market now, and the quality varies from good to bad. Have you chosen the right thermos cup? How to buy a good thermos cup? Today I will talk about how to choose a thermos cup. I hope it can help you choose a qualified thermos cup.

Have you chosen the right thermos cup? One of the tips for choosing a thermos cup: smell it

The quality of the thermos cup can be judged by smelling it. This is the simplest and most common way to identify the quality of a thermos cup. A good quality thermos cup will not have any pungent smell. A thermos cup of poor quality often emits a pungent smell. Therefore, when choosing a thermos cup, we can try to gently smell the inner liner and outer shell. If the smell is too strong, it is recommended not to buy it.

Have you chosen the right thermos cup? Tip 2 for choosing a thermos cup: Look at the tightness

Have you ever encountered such a situation: when you pour freshly boiled water into a thermos cup, the water becomes cold after a while. Why is this? This is because the sealing of the thermos cup is not good, causing air to enter the cup, causing the water to become cold. Therefore, sealing is also a detail that needs to be paid attention to when choosing a thermos cup. Generally speaking, the silicone sealing ring in the slot in the lid of the thermos cup not only has good sealing performance, but also prevents water leakage, thereby improving the insulation effect.

There are many brands of thermos cups on the market with varying quality, and the quality of silicone sealing rings also varies widely. Some sealing rings are prone to aging and deformation, causing water to leak from the cup lid. The sealing ring made of high-quality and environmentally friendly silicone material is different. It has excellent elasticity, high temperature resistance, aging resistance, and long service life, and can provide long-term and stable protection for the thermos cup.

Have you chosen the right thermos cup? The third tip for choosing a thermos cup: look at the material of the liner

Appearance is the basic responsibility of a thermos cup, but after using it, you will find that the material is more important than appearance. The quality of a thermos cup mainly depends on the material used in its liner. High-quality liner materials are generally stainless steel or stainless steel composite materials. These materials not only have good corrosion resistance, but can also effectively prevent the liner material from contacting the outside air, thereby ensuring that the temperature of the liquid is not easily destroyed.

The commonly used stainless steel materials for thermos cups are usually divided into three types, namely 201 stainless steel, 304 stainless steel and 316 stainless steel. 201 stainless steel has poor corrosion resistance. Long-term storage of acidic substances may cause the precipitation of manganese, which is harmful to human health. 304 stainless steel is a recognized food-grade stainless steel with high nickel content and excellent acid and alkali resistance. It is one of the most commonly used materials for the liner of thermos cups. Compared with 304 stainless steel, 316 stainless steel has better heat resistance and corrosion resistance due to the different contents of added metal elements such as chromium, nickel, and manganese. However, the price of a thermos cup with a 316 stainless steel liner will be higher than that of a thermos cup with a 304 stainless steel liner. Therefore, try to choose a stainless steel thermos cup produced by a regular manufacturer, pay attention to the information on the product packaging, labels or instructions, and check the product material or stainless steel grade on the packaging. Thermos cups with SUS304, SUS316 or 18/8 markings on the inner tank are more expensive, but safer.

Choosing a thermos cup seems simple, but it also contains a lot of knowledge. If you want to choose a high-quality thermos cup, you can judge it by smelling it, looking at the sealing, and looking at the material of the liner. The above are the tips for judging the quality of a thermos cup shared today. I hope everyone can pay attention to these details when choosing a thermos cup.
