Baby Bottle Valve Unit Segmentation for Air Ingestion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby bottles do not effectively prevent air ingestion during feeding, which can lead to colic in infants, as air enters the teat volume along with milk, and existing solutions are either complex or inefficient.
Innovation Solution
A baby bottle device with a container and teat featuring a valve unit outside the teat volume, where the second valve has a lower cracking pressure than the first valve, allowing air to enter the container volume without entering the teat volume, thereby reducing air ingestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air inlet valve is placed inside the teat volume, then air can enter the bottle to replace milk volume, but air will mix with milk in the teat volume causing colic
Solution Approach 1:
The invention divides the bottle internal volume into two separate zones: a teat volume containing milk that the infant consumes, and a container volume containing both milk and air. The partitioning element creates this segmentation, ensuring that air entering through the valve unit remains confined to the container volume and cannot mix with milk in the teat volume, thereby preventing colic while still allowing air replacement of milk volume.
Solution Approach 2:
The partitioning element acts as an intermediary structure between the teat volume and container volume. It includes a valve unit with a second valve that has lower cracking pressure than the first valve in the teat, allowing air to enter the container volume first before any air can potentially reach the teat volume. This intermediary structure controls the air inlet path to prevent direct air-milk mixing.
2Object-affected harmful factors
If flexible capsule or bag is used to contain milk with external venting valve, then air does not enter milk container volume, but device structure becomes more complicated
Solution Approach 1:
The partitioning element serves multiple functions simultaneously: it separates the teat volume from the container volume, provides structural support for the valve unit, enables air inlet control through the second valve, and prevents air-milk mixing. By combining these functions into a single integrated component rather than separate parts, the invention reduces overall device complexity while achieving effective colic prevention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces the amount of air in the teat volume, minimizing the risk of colic by ensuring air enters the bottle outside the milk volume, thus preventing air from mixing with the milk.
Implementation Method 1
The threshold of the valve unit is lower than the threshold of the first vent in the teat

AI summary
A baby bottle device (100) is provided which comprises a container (110) with a container volume (115), a teat (120) with a teat volume (125) and a valve unit (200). The teat comprises a first valve (112) for inletting air into the inside volume of the bottle (100). The inside volume of the bottle corresponds to the volume of the container (110) and the teat volume (125). The valve unit (200) with a second valve (210 230) is arranged outside the teat volume (125). The threshold of the vent unit is lower than the threshold of the first vent (112) in the teat.
