The invention relates to the field of infant articles, and particularly relates to a hygienic, safe nontoxic
nursing bottle. In the
nursing bottle, a photocatalyst intermediate layer is adopted, and the photocatalyst can oxidize and decompose various organic compounds and partial inorganic substances, and can sterilize, deodorize and purify the
nursing bottle; a polyethersulfone nipple is lightweight, fall-resistant, easy to clean, safe and free of
bisphenol A; a poly(
phenylene sulfone) bottle body is safe, nontoxic and free of carcinogenic substance
bisphenol A, can bear high temperature of 180 DEG C, can stand repeated high-temperature disinfection, has very good
chemical stability, and is safe, permeable, lightweight and fall-resistant; by a built-in
thermometer in the bottle body, the temperature of milk in the nursing bottle can be visually observed, and the
controllability is strong; and aiming at the easy inflation of the nursing bottle, a floating sphere body and a inflation-preventing bottle bottom are designed, thus the inner and outer
pressure balance of the nursing bottle is kept all along, a baby can easily suck milk, and milk
choking and bulkage are effectively prevented. The nursing bottle provided by the invention has high- and low-
temperature resistance,
aging resistance and no deformation, can be disinfected by water boiling, steam and the like; and the bottle body can be used for long time, and only the nipple is needed to replace.
