Asymmetric Plug Body Valve Positioning for Beverage Container Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plug bodies for beverage containers often lead to leakage when tilted or rolled over, as the pressure release valve can become immersed in the container's content, preventing proper operation.
Innovation Solution
The plug body design includes a spout part and a pressure release valve positioned differently, with a larger mass on the spout side to keep the pressure release valve above the spout, reducing the likelihood of immersion and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pressure release valve is positioned at the center of the container mouth, then the structure is simple and easy to manufacture, but the pressure release valve becomes immersed in the container content when tilted or rolled over, causing leakage or malfunction
Solution Approach 1:
The patent positions the pressure release valve asymmetrically relative to the spout part, specifically arranging it at a location that ensures the valve remains above the container content even when tilted or rolled over. This asymmetric positioning prevents immersion in content while maintaining structural feasibility
Solution Approach 2:
The patent considers the three-dimensional orientation and spatial relationship between the pressure release valve and spout part, arranging them in specific spatial positions that account for container tilting and rolling movements. This dimensional consideration ensures the valve remains in a reliable position regardless of container orientation
2Device complexity
If the pressure release valve and spout part are arranged at the same position, then the device structure is compact, but the pressure release valve cannot function properly when the container is tilted or rolled over
Solution Approach 1:
The patent deliberately positions the pressure release valve asymmetrically relative to the spout part, creating a specific spatial relationship where the valve is located at a position that remains above the container content during tilting or rolling, thus preventing malfunction while maintaining reasonable structural compactness
3Reliability
If the pressure release valve is positioned to remain above the spout part when tilted, then leakage is reduced, but the device structure becomes more complex
Solution Approach 1:
The patent achieves leakage prevention through simple asymmetric positioning of the pressure release valve relative to the spout part, without requiring additional complex mechanisms or components. The asymmetric arrangement naturally ensures the valve remains above the content during container movement
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
This configuration effectively reduces the possibility of content leakage and ensures proper operation of the pressure release valve when the container is tilted or rolled over.
Implementation Method 1
a mass on a spout part side is larger than a mass on a pressure release valve side... when attached to the container and having been tilted by a certain amount or more or completely rolled over, the pressure release valve is located above the spout part

AI summary
A plug body includes a spout part and a pressure release valve arranged at a position different from an arrangement position of the spout part. A mass on a spout part side is larger than a mass on a pressure release valve side.
