technical field

The utility model relates to a baby feeding bottle, in particular to an air return device used on the feeding bottle.

Background technique

The feeding bottle is mainly used to feed the baby, the baby has the ability to suck, and the baby obtains nutrition by sucking the pacifier. When the baby sucks on the pacifier, the pressure in the bottle will be weakened. Since the pacifier is mostly made of soft material, the pacifier will shrink, which will affect the baby's continuous normal sucking. In order to prevent the nipple from shrinking, there is an air return structure on the nipple or the end cap, which can make the pressure of the feeding bottle basically consistent with that of the outside world, without affecting the normal sucking of the baby. At present, the common return air structure on the market is set on the pacifier. Since the pacifier maintains a certain shape, the liquid in the bottle is easy to leak from the return air hole when sucking the pacifier, especially when the baby sucks the pacifier while lying down. The liquid has a certain pressure on the nipple, and the liquid is easy to leak from the return air hole. In view of the above problems, we have invented a return air device for feeding bottles, the return air device is installed between the nipple and the feeding bottle, when the baby sucks the nipple, the air between the mouth of the feeding bottle and the end cap will pass through the return air The device enters the feeding bottle, so that the pressure of the feeding bottle is basically the same as that of the outside world, which does not affect the baby's continuous normal sucking, and the liquid in the feeding bottle is not easy to leak from the air return device, ensuring that the feeding bottle is relatively clean.
