If you want to buy a vacuum cooling children's special kettle and thermos cup, the bottle body should be made of high-quality imported 304 stainless steel in terms of material selection. From the appearance pattern, it is difficult to fall off if it is made of stainless steel; The plastic parts must be food grade PP plastic. The sports kettle should be made of high-purity aluminum. It must be noted that pure aluminum with a purity of 99.5% is used in the brand label of the kettle.
The key to buy a children's kettle is the sealing of the spout. The sealing of the spout depends on the degree of coincidence between the cap and the spout thread. If the degree of coincidence is not high enough, there may be water leakage during normal use, which will bring a lot of inconvenience to use. In this regard, many parents must have some unpleasant experiences. In addition, the thread edges of children's water bottles bought in many irregular places are sharp. Although there are not many scratches on fingers and lips, they still happen occasionally. A good children's kettle will have a more humanized processing and treatment, that is, the edge of the thread will be made into an arc, so as to completely eliminate the possibility of scratching fingers and lips even with a very small probability.
When buying children's kettles, you need to pay attention to whether they have passed the relevant certification. First of all, it depends on whether the manufacturer has passed the quality system certification. If the manufacturer has passed the strict certification, it can eliminate many problems from the aspects of production and quality management system.
Good children's kettles, if carefully observed, will have some obvious performance in details: the surface and interior of good kettles will be very flat, without bottoms, blisters, depressions or protrusions caused by impurities; The screen printing pattern of the pot body has uniform printing color, clear edge, accurate color registration, firm adhesion and no stain; In addition, on the lid, because of the different materials, the color, gloss and texture will be different, and you can feel that the quality is higher. Some brands also have marks on the lid and the bottom of the kettle.
