Bottle Teat Slot Geometry for High-Flow Spill-Resistant Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bottle teats restrict the flow of food, leading to inefficient feeding and potential spills, as they require high suction pressure for liquid exit and have limitations in pressure balance due to ventilation valves.
Innovation Solution
A bottle teat made from soft elastic material with two parallel drinking slots that decrease in distance from the outer to the inner side of the suction nipple, allowing for increased flow without obstructing the natural sucking process and providing secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the drinking hole is constructed large to increase food flow, then liquid can exit without obstruction, but the infant cannot be trained in taking up food and food might be spilled
Solution Approach 1:
The single drinking hole is segmented into two parallel drinking slots, which increases the total flow area while maintaining control over the flow characteristics through the specific geometric configuration of the slots
Solution Approach 2:
The distance between the two drinking slots decreases from the outer side towards the inner side of the suction nipple, creating a dynamic flow control mechanism that allows adequate flow during sucking while maintaining sealing when not in use
2Reliability
If a ventilation valve is used for pressure compensation, then pressure balance is achieved, but the take-up of food is restricted
Solution Approach 1:
The geometric parameters of the drinking slots, particularly the varying distance between slots from outer to inner side, are optimized to provide both adequate flow during feeding and sufficient sealing when not in use, eliminating the need for separate ventilation valve mechanisms
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
The design enables efficient food flow during sucking while maintaining secure sealing, effectively training infants to drink from a cup by allowing high yield without spills, even when pressure is released.
Implementation Method 1
The bottle teat according to the present invention made from a soft elastic material has a hollow suction nipple... when sucking takes place, the region of the suction nipple located between the slots is somewhat lifted, so that big, unobstructed gaps are formed on both slots
Implementation Method 2
When no sucking takes place, the bottle teat of the present invention closes particularly safely, because the region of the suction nipple between the two slots forms a kind of wedge, which comes to sit very closely on the outer sides of the two slots

AI summary
A bottle teat made of a soft elastic material, comprising: a hollow suction nipple, a circumferential mounting edge for fixation to the bottle opening of a drinking bottle, a hollow transition zone between the mounting edge and the suction nipple, and two drinking slots extending from the outer side to the inner side of the suction nipple in an end region of the suction nipple, which are aligned in parallel to each other and whose distance from each other decreases from the outer side towards the inner side of the suction nipple.
