When people reach middle age, they have no choice but to soak wolfberry in a thermos cup. It is difficult for infants and young children to prepare milk when going out, so a small thermos cup can help. From more than ten or twenty yuan to three to five hundred yuan, how big is the difference? Milk, drinks, health tea, can it be filled with everything? Stainless steel, bullet, strong and durable, casually made?
Today, let’s find out together!
Beautiful, long-lasting heat preservation, made of 304, 316 stainless steel…
How to taste the quality of a stainless steel thermos cup?
At present, stainless steel vacuum cup products are based on the national mandatory standard GB 4806 series of standards and the national recommended standard GB/T 29606-2013 “Stainless Steel Vacuum Cup” to control product quality.
Focus on the following parameters:
Chemical safety indicators
01 Inner tank material:
The inner material of the stainless steel thermos cup is the key to safety. Good stainless steel materials are not only corrosion-resistant, high strength, durable, easy to clean and disinfect, but also have low metal dissolution.
02 Dissolved amount of heavy metals in the inner tank:
If excessive heavy metals such as arsenic, cadmium, lead, chromium, and nickel migrate out of the stainless steel liner during use, heavy metals accumulate in the human body and will affect and damage the heart, liver, kidneys, skin, gastrointestinal tract, respiratory and nerves, etc. System, therefore, my country’s GB 4806.9-2016 “National Food Safety Standard for Metal and Alloy Materials and Products for Food Contact” clearly stipulates the heavy metal content limits and monitoring conditions for stainless steel products.
03 Total migration and potassium permanganate consumption of nozzles, straws, sealing parts and liner coatings:
Total migration and potassium permanganate consumption reflect the content of non-volatile substances and soluble organic substances in food contact materials that can be transferred to food, respectively. These substances may have adverse effects on human health when entering the human body.
Physical security indicators
Including sealing, odor, strength of the thermos cup strap (sling), color fastness of the strap, etc. The seal is good and more insulating; abnormal odor affects the health of the human body or causes sensory discomfort; the color fastness of the strap (sling) is tested to see if the textile accessories will Color fades, reflecting product quality details.
Usage performance
Thermal insulation performance:
One of the important functions of a thermos cup is that the insulation performance is closely related to the production process, the vacuuming technology and sealing of the vacuum layer, and is also related to the capacity of the container, the presence or absence of an inner plug, the caliber, and the sealing result of the cup lid.
Impact resistance:
Check the durability of the product. These all test the design, material selection and technology of the manufacturing company, and reflect the product quality.
label identification
Label identification information guides consumers in purchasing and correct use, and is also a reflection of the added value of the product. It usually includes labels, certificates, instructions for use, etc. Wearing a well-made thermos cup with complete information label will definitely not be bad in quality, because the small label contains a lot of knowledge. Usually a good thermos cup label needs to convey at least the following information to consumers: product information, producer (or distributor) information, safety compliance information, usage precautions, maintenance information, etc.
01 Smell: Are the accessories healthy?
A high-quality thermos cup should have no odor or smell, or the smell should be light and easy to disperse. If you open the lid and the smell is strong and long-lasting, discard it decisively.
02Look: “object” and “certificate” are unified, and the identity is detailed
Look at the label identification
The label identity is the business card of the product. The labels are detailed and scientific, and can guide consumers to use them correctly. The label identification should include: product name, specifications, stainless steel type and grade of stainless steel accessories in direct contact with product liner, outer shell and liquid (food), material of plastic parts, thermal insulation energy efficiency, material name, compliance with national food safety requirements, production The name of the manufacturer and/or distributor, etc.; and the product should be clearly marked with a permanent manufacturer name or trademark mark in a conspicuous position.
Look at the material
Pay attention to the inner material of the thermos cup:
The material of the liner is obvious on the label. 304 stainless steel and 316 stainless steel are generally considered safe due to their relatively low migration of metal elements. But this does not mean that other stainless steel materials are unsafe. If the material is clearly marked on the label or instruction manual and it is stated to comply with the GB 4806.9-2016 standard, safety is guaranteed.
Pay attention to the inside of the lid and the material of the straw that are in direct contact with the contents:
The label of a qualified product will usually indicate the materials of these components and indicate whether they meet the requirements of national food safety standards.
Look at the appearance
Check whether the outer surface of the product is uniform in color, whether there are cracks or nicks, whether the welding joints are smooth and free of burrs, whether the printed text and patterns are clear and complete, whether the electroplated parts are free from exposure, peeling, or rust; check whether the switch button of the cup lid is normal and whether it is turned properly. And whether the performance and sealing are guaranteed; check whether each component is easy to disassemble, wash and reinstall.
Look at insulation energy efficiency
The most important reliability of the thermos cup is the insulation energy efficiency; under the specified ambient temperature of 20℃±5℃, the higher the retained temperature of 95℃±1℃ hot water after being placed for the specified time, the better the insulation efficiency.
03 Touch: Confirm whether you have met the right cup
Feel whether the liner is smooth, whether there are burrs on the mouth of the cup, the texture, the weight of the cup body, and whether it weighs in the hand.

Finally, a small thermos cup is also valuable. It is recommended to purchase the above strategies in regular shopping malls, supermarkets or brand stores to put them into practice.
In addition, “choose only the right ones, not the expensive ones” is a smart consumption behavior. If a thermos cup has excellent performance in all aspects, it must be expensive, and of course the brand value factor is not excluded. So, when purchasing, figure out your needs. For example, if it is only used for daily drinking water, there is no need to pursue a material of 304 or 316L; if the heat preservation for 6 hours meets the needs, of course there is no need to buy one that can keep heat for 12 hours.
Cleaning and disinfection before use is necessary
It is safer to sterilize by scalding with boiling water or neutral detergent before use. Preheating with boiling water will provide better heat preservation effect.
Avoid falls and collisions during use
Beats and collisions can easily cause the cup body to be damaged or deformed, and the welded parts will no longer be strong, destroying the insulation effect and shortening the life of the thermos cup.
A thermos cup can’t hold everything
During use, the inner tank should avoid contact with acid and alkali corrosive substances, and the thermos cup should not be used to hold dry ice, carbonated drinks, etc.; it should not be used to hold liquids such as milk, soy milk, juice, tea, traditional Chinese medicine, etc. for a long time.
Personal safety cannot be ignored
Children’s straw thermos cups should not be filled with liquids exceeding 50°C to avoid excessive air pressure in the cup and scalding the human body due to spray from the straw; do not overfill the water to avoid boiling water overflowing and scalding people when the cup lid is tightened.
Clean regularly and pay attention to hygiene
When cleaning, it is advisable to use a soft cloth to clean and avoid vigorous friction. Unless explicitly stated not to be washed in the dishwasher, nor should it be boiled or sterilized in water. Drink as soon as possible and pay attention to cleanliness to prevent the accumulation of dirt and evil (after drinking, please tighten the lid of the cup to ensure hygiene and cleanliness. After use, it should be cleaned and fully dried if not used for a long time). Especially after containing food with strong color and smell, it should be cleaned as soon as possible to avoid staining of plastic and silicone parts.
