Agrochemical Container Closure With Radial Seal Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closing devices for agrochemical containers fail to provide a sufficiently tight connection between the sealing element and the closing element, leading to a risk of uncontrolled leakage during transport and storage.
Innovation Solution
Incorporating a sealing protrusion at either the receiving arrangement or the sealing element, or both, which extends radially to the closing axis, ensuring a liquid-tight seal and maintaining a defined pre-tensioning for a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing element is connected with the closing element using conventional connection methods, then the device structure is simple, but the connection is not sufficiently tight and leakage risk exists during transport and storage
Solution Approach 1:
The connection structure is divided into distinct functional elements: a receiving arrangement on the closing element and a sealing protrusion on the sealing element. This segmentation allows each component to be optimized independently for its specific function while achieving reliable sealing through their interaction.
Solution Approach 2:
The sealing protrusion is designed with a curved surface that extends radially from the closing axis, creating a conformal seal that adapts to the receiving arrangement's geometry. This curved configuration ensures comprehensive contact and sealing across the entire sealing area, preventing leakage paths.
2Reliability
If the sealing element is made flexible to improve sealing adaptability, then the sealing performance improves, but the structural stability and resistance to deformation decrease
Solution Approach 1:
The sealing element is designed with non-uniform properties: the sealing protrusion and receiving arrangement areas are made flexible to ensure adaptive sealing contact, while other portions of the sealing element maintain higher rigidity to preserve structural stability and prevent unwanted deformation during handling and storage.
Solution Approach 2:
The curved geometry of the sealing protrusion working with the receiving arrangement creates a mechanically stable connection that distributes loads effectively. This curved interface provides both flexibility for sealing adaptation and geometric stability to resist deformation under external forces.
3Reliability
If the sealing protrusion extends radially to the closing axis, then the sealing area increases and leakage is prevented, but the manufacturing precision requirements increase
Solution Approach 1:
The sealing protrusion is designed with specific geometric parameters including radial extension to the closing axis and an angled configuration (30-60 degrees relative to the closing axis). These parameter specifications provide clear manufacturing guidelines while ensuring adequate sealing area and effective leakage prevention.
Solution Approach 2:
The curved surface of the sealing protrusion is designed with specific radius parameters that balance sealing effectiveness with manufacturability. The curved geometry provides gradual contact transitions and distributes sealing forces, reducing the impact of minor dimensional variations while maintaining reliable sealing performance.
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 sealing protrusion enhances the tightness of the connection, minimizing the risk of leakage and providing a reliable seal, even under conditions of out-of-roundness, thus ensuring safe transport and storage of agrochemicals.
Implementation Method 1
the sealing protrusion abuts on the sealing area between the receiving arrangement and the sealing element for at least liquid-tightly sealing the fluid channel
Implementation Method 2
the sealing element may be configured in such a manner, such that the sealing protrusion abuts in the sealed state of the closing device at the sealing area under tension
Implementation Method 3
the sealing protrusion reduces the surface pressure to a linear distributed load and is therefore able to balance out-of-roundness of the sealing element and/or the closing element
