Infant Feeding Teat Grooved Venting Single-Piece Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant feeding bottles with a two-piece teat and collar arrangement often become over-tightened, leading to an airtight seal that prevents air from entering the bottle, reducing fluid flow due to the flexible material being sandwiched between hard surfaces, and require unnecessary handling for cleaning and assembly.
Innovation Solution
A single-piece outlet portion with a flexible teat moulded over a hard collar, featuring grooves on the collar's undersurface to allow air venting and prevent airtight sealing, ensuring consistent fluid flow and natural suction action, replicating the breast feeding experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the flexible teat is sandwiched between the hard collar and the hard bottle rim to secure assembly, then the connection strength is improved, but the flexible material becomes deformed and airtight, preventing air entry and reducing fluid flow
Solution Approach 1:
The invention divides the sealing function into two separate components: the flange provides the seal between the teat and bottle, while the collar provides structural support and attachment. This segmentation allows the flange to remain soft and flexible for sealing without being over-compressed by the collar, maintaining air flow paths while ensuring secure assembly.
2Ease of repair
If the two-piece teat and collar arrangement is used to allow disassembly for cleaning, then the ease of cleaning is improved, but the device complexity increases due to multiple parts requiring assembly and handling
Solution Approach 1:
The invention merges the teat and collar into a single integrated piece where the flange is directly formed as part of the teat structure. This eliminates the separate collar component, reducing the number of parts to assemble and clean while maintaining the functional benefits of both the teat and collar structures.
3Strength
If the flange is overtightened during assembly to secure the teat to the bottle, then the connection strength is improved, but the flexible material is deformed and becomes airtight, preventing air from entering the bottle
Solution Approach 1:
The invention applies different material properties to different parts of the teat structure: the flange is made soft and flexible to create a seal without blocking air paths, while the body of the teat maintains sufficient firmness for structural integrity and infant comfort. This local differentiation of material properties allows secure assembly without airtight sealing.
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 solution enhances fluid flow by allowing air to enter the bottle during use, maintaining a vacuum for natural suction and reducing leakage, while simplifying assembly and cleaning by eliminating the need for multiple parts and minimizing over-tightening issues.
Implementation Method 1
a flexible teat member (17) made from an elastomeric material having an outlet (19) formed therein and configured to be received within an infant's mouth to facilitate flow of fluid to the infant by way of a sucking action
Implementation Method 2
The grooves (30) are configured to function as a vent when a suction force is applied to the teat member (17)

AI summary
There is disclosed a feeding teat for use on a drinking receptacle. The teat has an outlet member having an outlet through which fluid from the receptacle is delivered under pressure supplied by a user of the receptacle and a collar portion that attaches to an opening of the receptacle. The under surface of the collar portion abuts with the upper surface of the opening of the receptacle to form a substantially sealed engagement between the outlet member and the receptacle. Either the under surface of the collar portion or the upper surface of the opening has at least one vent configured such that when pressure is applied to the outlet member the vent member permits controlled ingress of air into the container to facilitate flow of fluid from the outlet and when the pressure is removed the vent prevents ingress of air into the container to facilitate a controlled vacuum pressure with the container.
