Vented Side Air Channel Spout for Fast Liquid Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spouts, both non-vented and vented, suffer from slow flow rates due to pressure differences and inconsistent venting, which hampers the efficient transfer of liquids like chemicals, and are often costly.
Innovation Solution
A detachable self-venting spout with a side air channel and thread shape tube design that includes a one-way valve to balance air pressure and enhance flow, allowing for faster liquid transfer without reducing the pouring orifice cross section, and is flexible and cost-effective due to a one-piece blow-molded construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-vented spout is used, then the structure is simple and cost is low, but the flow rate is very slow or no flow at all due to air pressure difference
Solution Approach 1:
The spout is divided into separate functional components: a venting mechanism with movable flap, a pouring channel, and a connection interface. This segmentation allows the venting function to be added without complicating the overall structure, enabling fast flow rate while maintaining manufacturing simplicity
Solution Approach 2:
A movable flap acts as an intermediary element that selectively opens or closes the venting passage based on liquid flow conditions. This intermediary mechanism automatically balances air pressure without requiring complex external controls, resolving the contradiction between simple structure and high productivity
2Productivity
If a traditional vented spout is used, then the flow rate is improved, but the venting effect is inconsistent due to structure limitations
Solution Approach 1:
The venting flap is designed to be dynamic and responsive, automatically adjusting its position based on pressure differential and liquid flow. This dynamic adjustment ensures consistent venting effectiveness throughout the pouring process, maintaining reliable performance without compromising flow rate
Solution Approach 2:
The venting mechanism parameters (flap angle, passage size, material properties) are optimized to respond consistently to pressure changes. This parameter optimization ensures that the venting effect remains uniform and reliable across different pouring conditions, resolving the inconsistency issue
3Reliability
If the pouring orifice cross section is reduced to increase venting, then venting effectiveness is improved, but the flow rate is reduced
Solution Approach 1:
The spout structure is segmented into separate venting and pouring pathways. The venting flap controls air flow through one passage while the pouring orifice remains fully open for liquid flow. This segmentation allows both venting effectiveness and high flow rate to be achieved simultaneously without compromising either function
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 spout significantly accelerates the flow rate of liquids, maintaining consistent venting and reducing storage space, while being economical and efficient for chemical transfer.
Implementation Method 1
the air from air channel will get into flowing liquid and, form small air bubbles. Some small air bubbles will flow back into container and create balanced air pressure inside and out of container
Implementation Method 2
the air from air channel will get into flowing liquid and, form small air bubbles. Some small air bubbles will flow back into container
Implementation Method 3
The thread shape portion of spout will create a spinning liquid flow, which will accelerate flow speed as well
Implementation Method 4
The side air channel has a plastic valve that prevents liquid back out from the air channel

AI summary
This vented spout relates to a detachable pouring spouts that can be used to transfer liquid contents from a filling container to a receiving container. More particularly, the present invention relates to a detachable self-venting, non-spilling pouring spout. This vented spout has a side air channel or air channels including one way valves that prevent liquid back out from the air channel and also does not reduce the pouring orifice cross section which would result in accelerating the flow rate of substance. The vented spout has a thread shape portion which will create spinning flow and enhancing flow rate as well. It's also flexible so that the spout can be bend to different directions which helps reduces storage space due to the bending.
