[0002] In life, many families with newborns will buy some infant milk powder to feed their babies. The existing milk powder is mostly canned and stored. Each time the milk powder is brewed, the milk powder must be measured with a milk powder spoon, and one spoon is one unit of amount. However, each infant has different adaptability to the concentration of milk powder after brewing, and the required concentration is not an integer spoon amount when brewing. Therefore, it is impossible to accurately grasp the amount of milk powder each time it is brewed, which will make the brewing ratio unsuitable and easily cause the infant to have a stomachache. In addition, when taking out the milk powder from the existing milk powder can, the lid of the milk powder can is opened before taking it out. Each time the lid of the milk powder can is opened, the milk powder in the milk powder can will come into contact with the outside air once. After long-term use, the unused milk powder in the milk powder can is prone to some chemical reactions with the air, causing the milk powder to deteriorate and affecting the health of the infant.
