Built-in waterproof ventilator air guide feeding bottle

Abstract

The invention relates to a built-in waterproof ventilator air guide feeding bottle, which consists of a nipple (1), a bottle body (2), a screwing ring (3), an air guide ring (4) and a waterproof ventilator (5). The feeding bottle is additionally provided with a built-in waterproof ventilator air guide assembly on the basis of an ordinary feeding bottle, so air in the bottle can be supplemented in time through the built-in waterproof ventilator air guide assembly in the feeding process, the negative pressure formation and the air bubble generation in the bottle during continuous sucking are prevented, and the breathing difficulty caused by the negative pressure and the flatulence, hiccup and milk vomiting phenomena caused by air bubble suction into human bodies are avoided. The feeding bottle disclosed by the invention has the advantages that a waterproof ventilator air guide system is adopted, gas and liquid passages are thoroughly separated, and the defects of milk filling less than half volume, milk overflowing during bottle capped heating, milk overflowing from capped bottles at excessive milk temperature, and milk overflowing during the milk preparation through bottle shaking of the existing liquid storage pipe type air guide bottle are overcome.

Description

Technical field [0001] The invention relates to a feeding bottle, in particular to a feeding bottle which does not generate negative pressure in the bottle during use. technical background [0002] Ordinary feeding bottles will form a negative pressure in the bottle when they are continuously sucked, making it difficult to suck out, and when the air is pressed in from the nipple, air bubbles will be generated in the drinking liquid. vomiting phenomenon. At present, there are a certain number of technical inventions at home and abroad for the ventilation problem of feeding bottles, among which it is relatively mature, and what has been produced and marketed is a U.S. patent disclosed in 1996 by Craig. I. Brown et al. , the patent uses a liquid storage tube and a ventilation device extending from the center of the liquid storage tube and opening to the screw mouth of the feeding bottle, which successfully solves the problem of negative pressure and air bubbles generated when ...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a feeding bottle with a built-in air guide system, in which the gas and liquid passages are always separated at any time and at any angle, while maintaining the anti-negative pressure performance and hygienic convenience, it overcomes the The existing liquid-storage tube-type air-guided feeding bottle has the defects of holding milk below half volume, milk overflowing when the capped bottle is heated, milk overflowing when the milk temperature is too high, and milk overflowing when shaking the bottle to adjust the milk
