Vented Liquid Container Bottom Closure with One-Way Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby bottles with bottom venting systems are susceptible to dirt and germ entry due to ambient air ingress through holes, leading to potential clogging and contamination issues.
Innovation Solution
A vent system that uses a solid closure member with a one-way valve and air conduit between complementary coupling elements, allowing ambient air to enter the container without requiring holes in the bottom closure, thereby preventing dirt and germ entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bottom openings with holes are used for air ingress, then air can enter the container during drinking, but dirt and germs can enter together with ambient air
Solution Approach 1:
The vent system is segmented into multiple functional components: a solid closure member that seals the bottom opening, a sealing member with a bore for air passage, and a one-way valve mechanism. This segmentation allows the air ingress function to be separated from direct exposure to external contaminants, as air must pass through the sealed bore and valve mechanism rather than through open holes in the bottom closure.
Solution Approach 2:
The one-way valve acts as an intermediary element between the external environment and the container interior. It selectively permits air passage while blocking contaminants, serving as a mediator that allows the necessary air flow function while preventing the harmful contamination that would otherwise occur through direct bottom openings.
2Ease of operation
If holes are provided in the bottom closure for air inlet, then air can enter the container, but the aperture is difficult to clean and can be clogged
Solution Approach 1:
The air inlet function is segmented into the sealing member bore and the one-way valve as separate components. This segmentation allows the valve to be designed as a removable or replaceable element that can be easily cleaned or replaced if clogged, rather than having the air inlet integrated directly into the bottom closure where it would be difficult to access for cleaning.
Solution Approach 2:
The one-way valve serves as an intermediary component that can be independently maintained. When the valve becomes clogged, it can be removed and cleaned separately from the closure member, facilitating easy maintenance without requiring disassembly of the entire bottom closure structure.
3Object-affected harmful factors
If a solid closure member with one-way valve is used, then dirt and germ entry is prevented, but the structure becomes more complex
Solution Approach 1:
The sealing member and one-way valve are merged into a single integrated component in many embodiments. The sealing member includes both the sealing element that engages with the closure member and the valve mechanism within the same piece, reducing the number of separate parts while maintaining the contamination prevention function.
Solution Approach 2:
The sealing member serves multiple functions simultaneously: it provides the seal between the closure member and container, creates the air passage bore, and incorporates the one-way valve mechanism. This multi-functionality reduces overall system complexity by combining what could be separate components into a single universal element.
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 effectively seals the bottom opening of the container, preventing liquid leakage while allowing air to enter and reducing the risk of contamination, thus enhancing cleanliness and usability.
Implementation Method 1
a one-way valve sealing the bore against liquid passage from the container and selectively permitting air passage through the bore into the container
Implementation Method 2
a sealing element configured to seal a rim of the container bottom opening
Implementation Method 3
an air conduit extending from the coupling elements to a space in the vent system which is in operative communication with the bore
