Nursing bottle with biased nipple

Abstract

The invention provides a nursing bottle with a biased nipple, and belongs to the industry of infant and children supplies. The nursing bottle comprises a bottle body, a bottle cap, a nipple with a one-way vent valve and a dustproof cover, wherein an outer thread is formed in an opening end of the bottle body; an inner thread and a center hole are formed in the bottle cap; the nipple is arranged in the center hole; the outer thread of the bottle body is connected with the inner thread of the bottle cap to form a sealed space; a feeding opening and at least one one-way valve which protrudes inwards are arranged on the nipple; an air intake opening is formed in the top part or the side surface of the one-way valve; an annular groove which is used for relieving deformation of the nipple and surrounds the one-way valve is arranged at the periphery of the root part of the connected part of the inside of the nipple and a large arc surface; an annular body which protrudes upwards is arranged on a seal edge of the lower part of the nipple for preventing the nipple from falling off; the annular groove which protrudes out of the annular body downwards and sinks into the bottle cap upwards is arranged at the lower part of the edge of the center hole of the bottle cap; a bulge body aligned with the dustproof cover is arranged on the edge of the outer surface of the bottle cap; and a leak-proof device which is in contact with the feeding opening of the nipple and is used for preventing a liquid in the bottle body from flowing outside is arranged in the top part of the dustproof cover; and a groove aligned with the feeding opening of the nipple after the feeding opening of the nipple and the bottle cap are clamped is arranged at the inner side of the edge.

Description

technical field [0001] The invention relates to the field of feeding bottles, in particular to an anti-colic feeding bottle and a nipple used for the feeding bottle. Background technique [0002] A traditional feeding bottle consists of a bottle body, a bottle cap, a dust cover and a nipple. A bottle having an open neck with external threads formed around the neck adjacent the opening; a cap having internal threads for screwing onto the external threads on the neck of the bottle; a nipple having a rim that fits over the cap and the top edge of the neck, whereby a liquid-tight seal between the bottle body and the nipple can be achieved. The teat is positioned on the teat away from the sealing edge and has a feeding opening at the end of the teat adapted to discharge liquid when the bottle contains feed. [0003] Since the feeding opening of the pacifier is between the body of the bottle and the center of the pacifier circle, when the liquid in the bottle is less than half, ...

AI Technical Summary

Problems solved by technology

[0003] Since the feeding opening of the pacifier is between the body of the bottle and the center of the pacifier circle, when the liquid in the bottle is less than half, infants can easily inhale the air in the bottle into the abdomen; the feeding bottle is tightly sealed except for the feeding opening on the pacifier. When the baby sucks the liquid, the volume of the liquid in the bottle decreases, the volume of the air increases, and a negative air pressure is generated, which increases the resistance of the liquid flowing out from the feeding opening of the nipple, making the baby quite laborious when sucking. When a large negative air pressure is formed in the bottle , so that the nipple is sucked deflated, the baby will easily enter the abdominal cavity with atmospheric air, and the gas will accumulate in the baby's abdomen, causing the baby to spit up milk, and the excess air in the stomach and digestive tract will cause abdominal pain

[0004] In order to solve the above-mentioned problems, there are also various feeding bottles on the market that can prevent flatulence and the like. It is well known to include a one-way ventilation valve in the teat. The one-way ventilation valve is usually close to the bottom of the sealing edge of the teat. After tightening, it will block part of the one-way ventilation valve, resulting in poor air intake effect

[0005] CN103561711A patent discloses a feeding bottle, the nipple is installed from the upper part of the bottle cap, which does not conform to the usual habit of nipple installation, and has poor practicability; Due to the eccentric design, when the baby bottle is assembled after cleaning and disinfection, the anti-liquid outflow device on the top of the dust cover is not easy to align with the feeding opening of the nipple, and the liquid in the bottle is easy to flow out after the bottle is tilted or dumped risks of
