Volume-variable feeding bottle with passively expended expensive body

Abstract

The invention provides a volume-variable feeding bottle with a passively expended expensive body The feeding bottle comprises a nipple, a bottle cover and a bottle body, wherein the upper bottom and the lower bottom of the bottle body are opening; and the opening at the upper bottom is provided with the nipple. The feeding bottle is characterized in that: a passive elastic expansive body is arranged at the lower bottom in the bottle body; the lower end of the passive elastic expansive body is hermetically connected with the lower opening of the bottle body; and when the nipple is sucked, the passive elastic expansive body is passively expanded to extrude liquid in the bottle body, so that the liquid flows from the nipple smoothly. The feeding bottle overcomes the defects of feeding bottles with various structures, and has the advantages that: an infant can suck milk smoothly, does not choke, have no flatulence and is ease to use, and milk is not left at all after the infant sucks, themilk is prevented from leaking from the bottom of the bottle, the feeding bottle is convenient to use and easy to clean and the like.

Description

technical field [0001] The invention relates to a feeding bottle, in particular to a passive expansion variable volume feeding bottle of an expansion body. Background technique [0002] The problems of the previous feeding bottle are: first, the traditional feeding bottle must be ventilated or pressurized into the water, so the user forms a large number of air bubbles when sucking, which is laborious and easy to cause abdominal flatulence and choking; second, during the sucking process, air contact After breastfeeding, it will cause nutrient loss and easy to deteriorate; third, when feeding, not only should you fix the posture but also pay attention to the angle of the bottle, otherwise the baby will easily inhale air and cause flatulence. The 4th, because bottle mouth is little, depth is big, and feeding bottle is not easy to clean. [0003] For addressing the above problem, people have designed a kind of piston type baby feeding bottle as provided by Chinese document CN11...

AI Technical Summary

Problems solved by technology

[0002] The problems of the previous feeding bottle are: first, the traditional feeding bottle must be ventilated or pressurized into the water, so the user forms a large number of air bubbles when sucking, which is laborious and easy to cause abdominal flatulence and choking; second, during the sucking process, air contact After breastfeeding, it will cause nutrient loss and easy to deteriorate; third, when feeding, not only should you fix the posture but also pay attention to the angle of the bottle, otherwise the baby will easily inhale air and cause flatulence

Fourth, due to the small mouth and large depth, the feeding bottle is not easy to clean

The size requirements are extremely high, so mass production is not possible; second, the piston will expand and contract due to temperature changes, so the piston must be replaced when the temperature changes, which is troublesome for users; third, it is not easy to return the piston after being sucked to the top of the bottle To the bottom, it is inconvenient to take it off for cleaning

[0004] Another Chinese patent 98201788 discloses a vacuum volume-changing feeding bottle. It adopts an inner and outer bottle structure, and squeezes the inner bottle through the nipple to shrink the inner bottle to produce milk. The defect of this feeding bottle is that it cannot suck the milk in the bottle. strenuous
