Feeding bottle

Abstract

A feeding bottle, comprising a feeding bottle body, a nipple cover and a guide sheet, wherein a nipple is arranged on the nipple cover, the nipple cover is rotatably connected with the upper end of the feeding bottle body through threads, the guide sheet is pressed against the inside of the nipple cover, guide grooves are arranged on the top surface of the guide sheet, the guide grooves communicate with the feeding bottle body, a protrusion protruding towards the nipple is arranged in the middle of the guide sheet, when the guide sheet is pressed against the inside of the nipple cover, the topsurface of the protrusion and the inner wall of the nipple define a cavity in the upper part of the nipple, the top end of the protrusion is provided with a milk outlet hole, the milk outlet hole communicates with the feeding bottle body, air inlet passages are arranged on the side wall of the nipple, air inlets of the air inlet passages are arranged on the outer wall of the nipple, air outlets of the air inlet passages are arranged on the inner wall of the nipple and are positioned outside the cavity defined by the top surface of the protrusion and the inner wall of the nipple, and the air inlet passages communicate with the feeding bottle body. The feeding bottle is simple in structure, not complicated in manufacturing process and low in cost, and components inside the feeding bottle are convenient to clean.

Description

technical field [0001] The invention relates to the field of baby products, in particular to a feeding bottle. Background technique [0002] When a baby uses a feeding bottle to suck milk, sometimes there will be hiccups, abdominal pain and other flatulence phenomena. Most of these phenomena are due to the fact that the feeding bottle does not return air and negative pressure is generated in the bottle. The baby cannot suck milk and is still sucking and swallowing from the nipple A large amount of air is caused, so a large number of anti-colic feeding bottles have appeared on the market. [0003] There are two basic ideas for existing anti-colic feeding bottles. The first idea is to improve the nipple cover or parts in similar positions. The cover (nipple groove) is added with an air vent that communicates with the outside world, and then a row of air holes that communicate with the inside of the bottle are added on the exhaust rubber pad, thereby balancing the atmospheric ...

Problems solved by technology

For example, the Chinese invention patent with the publication number CN 202892447 U discloses an anti-flatulence feeding bottle. The idea is to design the ventilation structure at the bottom of the feeding bottle to ensure that the feeding bottle is in a gas return state and reduce the phenomenon of flatulence in babies. However, this technical solution has defects. The reason is that when the ventilation structure is disassembled and cleaned for a long time, it will affect the sealing performance of the bottom of the feeding bottle, which may cause damage to the feeding bottle. There is a certain amount of air, so when the baby starts to suck, he will inhale a lot of air, and it will also cause a certain degree of flatulence
