Description

Nursing bottle warmer

The present invention relates to a bottle preheating warmer for preheating and warming a baby bottle containing water for burning powdered milk to a range similar to the temperature of breast milk.

Babies who are not born can't eat rice, so they usually feed it with water. These babies do not have self-control, so if they are hungry, they are ready to take care. Suddenly, when the baby is hungry, parents are often hungry for milk powder to pass on to the baby.

However, the process of burning formula is not so simple. For example, after cutting off the water, it is cooled down to about 40 ℃ ~ 50 ℃, which is good for children, and the powdered milk is put in a bottle. At this time, if the temperature of the water is high, put the bottle again in cold water to cool. Or, put powdered milk in the refrigerator beforehand to cool the baby's temperature to eat. As such, the process of making milk for the child takes at least 5 to 10 minutes. During this time, the child will cry out, and the mother will be in a hurry and will not be restless. On the other hand, at a high temperature of 60 ° C. or higher, it is important to set an appropriate temperature because nutrients in the milk powder are destroyed.

In addition, the child should be fed with powdered milk as much as 5 to 8 times a day, and every time the formula is burned, the process of adjusting the water temperature is repeated. In particular, newborns less than 4 months of age need to be fed at night, so the whole family suffers from sleep deprivation at this time.

The present invention has been made to reduce the discomfort as described above, it is an object of the present invention to provide a bottle preheating warmer to preheat and keep warm in a bottle of milk for burning powdered milk and furthermore not to destroy the nutrients of powdered milk. .

Still another object of the present invention is to provide a bottle preheating warmer that allows parents to set a pre-feeding time in advance and informs them of a melody or a beep when the time comes.
