How To Choose Stainless Steel Vacuum Flask?
Oct 15, 2021
1. Smell: Are the accessories healthy?
A high-quality vacuum flask should have no peculiar smell or smell that is slight and easy to disperse. If the lid is opened, the smell is strong and lasting, then it should be discarded decisively.
2. Look: the "things" and "proofs" are unified, and the identity is detailed
(1) Look at the label
The label logo is the business card of the product. The label identification is detailed and scientific, which can guide consumers to use it correctly. The label identification should include: product name, specification, product liner, shell and stainless steel accessories directly contacted by liquids (food) stainless steel type and brand, plastic parts material, heat preservation efficiency, material name, meet national food safety requirements, production The name of the manufacturer and (or) the distributor, etc.; and the manufacturer should be clearly marked with a clear and permanent name of the manufacturer or trademark in the obvious position of the product.
(2) Look at the material
a) Pay attention to the material of the inner container of the vacuum flask: The inner container material is obvious on the label. 304 stainless steel and 316 stainless steel are generally considered to be safe due to the relatively low migration of metal elements. But this does not mean that other materials of stainless steel are not safe. The label or manual clearly identifies the material and shows that it meets the GB 4806.9-2016 standard. Safety is guaranteed.
b) Pay attention to the inside of the cup lid and the material of the straw that is in direct contact with the content: The label of a qualified product usually indicates the material of these parts and indicates whether they meet the requirements of national food safety standards.
(3) Look at the appearance
Whether the outer surface of the product is uniform in color, whether there are cracks or gaps, whether the welding place is smooth and free of burrs, whether the printed text and patterns are clear and complete, whether the electroplated parts are free of the exposed bottom, peeling, or rust; check whether the switch button of the cup lid is normal, and rotate it. Whether the performance and tightness are guaranteed; check whether the components are easy to disassemble, wash and reassemble.
(4) Look at thermal insulation energy efficiency
The most important reliability of the vacuum flask is the thermal insulation energy efficiency; the product is placed at the specified ambient temperature of 20 ℃ ± 5 ℃, 95 ℃ ± 1 ℃ hot water after the specified time, the higher the retention temperature, the better the thermal insulation performance.
3. Touch: confirm if you meet the right cup
Check whether the inner tank is smooth, whether there are burrs on the mouth of the cup, feel the texture, how heavy the cup is, and whether it weighs on your hands.
Finally, small vacuum flasks are also worthwhile. The above strategies are recommended to be purchased at regular shopping malls, supermarkets, or brand franchise stores.
In addition, "only choose the right ones, not the expensive ones" is smart consumer behavior. If the performance of a vacuum flask is excellent, it must be expensive, and of course, the brand value factor is not ruled out. Therefore, when shopping, find out your own needs. For example, if it is only used for daily drinking, there is no need to pursue a certain material of 304 or 316L; if the heat preservation is 6 hours to meet the demand, of course, there is no need to buy the heat preservation for 12 hours.
