Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas replacement methods for containers, such as beverages, face challenges in simultaneously reducing residual oxygen, replacement gas consumption, and liquid spillage, with previous solutions often requiring increased gas flow rates that lead to higher costs and inefficiencies.
Innovation Solution
The method involves a gas replacement device with a nozzle design featuring a larger opening angle (100° to 130°) between outermost walls and a higher blowout port height, allowing the replacement gas to effectively cover a greater area within the container, reducing gas consumption and spillage while maintaining or improving replacement efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the replacement gas flow amount is increased to improve the gas replacement rate, then the residual oxygen amount decreases, but the replacement gas consumption increases
Solution Approach 1:
The patent changes the geometric parameters of the nozzle, specifically increasing the opening angle from conventional values to 100-130 degrees and adjusting the blowout port height to 5-15mm. These parameter changes optimize the gas flow distribution pattern, enabling effective replacement with reduced gas consumption while maintaining high replacement rates
Solution Approach 2:
The patent introduces a vertical dimension to the gas flow by elevating the blowout port height, creating a three-dimensional flow pattern that combines vertical and radial components. This dimensional change allows the gas to reach the liquid surface more effectively and creates a more efficient replacement pattern throughout the headspace volume
2Reliability
If the replacement gas flow amount is increased to improve the gas replacement rate, then the residual oxygen amount decreases, but the liquid spillage increases
Solution Approach 1:
By optimizing the nozzle opening angle to 100-130 degrees and setting the blowout port height to 5-15mm, the patent creates a controlled flow pattern that replaces gas efficiently without generating excessive turbulence. This parameter optimization allows achieving high replacement rates with lower flow amounts, thereby preventing liquid spillage
Solution Approach 2:
The patent applies partial action by using just enough replacement gas flow to achieve the required replacement rate, rather than using excessive flow. The optimized nozzle geometry ensures that this partial flow is distributed efficiently to achieve complete gas replacement without the need for high flow rates that would cause spillage
3Productivity
If the nozzle opening angle is increased to improve gas distribution, then the replacement efficiency improves, but the device complexity increases
Solution Approach 1:
The patent achieves improved replacement efficiency by changing only the geometric parameters of the existing nozzle structure - specifically the opening angle (100-130 degrees) and blowout port height (5-15mm). This approach maintains structural simplicity while significantly improving performance through parameter optimization rather than structural complexity
Solution Approach 2:
The nozzle is segmented into distinct functional zones: the blowout port at a specific height, the wind direction adjustment plate, and the angled outermost walls. This segmentation allows each component to perform its specific function optimally while keeping the overall structure relatively simple and modular

AI summary
Disclosed is a device for gas replacement capable of reducing the amount of replacement gas, improving a gas replacement rate, and reducing the amount of split liquid. In a replacement nozzle (11) which blows the replacement gas toward a container opening portion symmetrically about a center line in the container radial direction, the space between nozzle port outermost walls is divided with a plurality of wind direction adjustment plates (16a, 16b) to generate a plurality of blowout ports. The replacement gas flow blowing along the outermost walls of the nozzle opening are so blown inward as to form an angle of 100° to 130°. Moreover, the replacement gas is blown from the replacement nozzle to the range between the level lower than the end of the can opening by one third or more the height of the can neck portion and the level equal to or higher than the height of the can cover.
