The design of the bottle nipple lies in the following key points:

a. Additional air vent points and movable plug: air vent holes and active plugs are set at the bottom of the pacifier, both of which are used to prevent the milk from overflowing due to the large size of the aerated milk, which may cause the baby to vomit or choke because it is easy to breathe in air.

b. Anti collapse design: anti collapse design: a circular cloth wedged diversion point is designed at the base of the nipple to prevent the nipple from contracting due to sucking and blocking the outlet.

c. Subdivide different sizes and types of suction heads: Subdivide different sizes and types of suction heads: Depending on the age of the baby and the scope of application, design different suction functions.

D. The attached flow regulator is a small slice placed between the base of the pacifier and the bottleneck. This function is to fill the pacifier with milk and prevent the baby from inflating due to excessive air inhalation. The use method is to put the pacifier into the rotary cover, and then put the flow regulator into the pacifier, so that the regulator is parallel to the base of the pacifier.
