ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to an improved structure of nipple for an infant, and particularly to a nipple that can remove the lactic acid remained on the incisors of the infant after feeding in order to prevent “nipple-type” tooth decay.
It is reported that the infant delivery rate has climbed up to 80 millions in average per year, and all the infants are facing a common problem—tooth decay, or the so-called “nipple type” tooth decay in medical science. An infant with baby teeth is liable to have his incisors decayed owing to lack of saliva secretion so that the lactic acid will remain to etch his incisors while it is not the case for his rest teeth, which are always wetted by the saliva. However, this phenomenon of “nipple type” tooth decay would not happen to those babies who are fed with mother's milk, and nevertheless, it comes back very soon after a feeding bottle is substituted for the mother's milk for the reason that a baby's teeth grow large enough to accidentally bite and hurt his mother's nipple when sucking.
SUMMARY OF THE INVENTION
The primary object of this invention is to provide a nipple made of silicon rubber that can remove the lactic acid remaining on a baby's teeth, which is then carried away by the saliva, when the baby is sucking a feeding bottle or a false (pacifying) nipple.
Another object of this invention is to massage the gums for reducing itch which accompanies tooth growth in addition to removing the lactic acid remaining on the incisors after feeding.
In order to realize the abovesaid objects, at least or more than two pieces of an annula body are spaced on a sucking part of the nipple in the way that a clearance is provided between the two adjacent bodies. When a baby is sucking the nipple, he is holding the sucking part in his mouth, meanwhile, his upper and lower incisors are inserted in the clearance, and the bodies pinch against the upper and the lower incisors on both sides to remove the remaining lactic acid on the incisors for preventing the so-called “nipple type” tooth decay recognized in medical science.
