Pivoting Closure Assembly for Repeatable Beverage Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resealable closure assemblies for beverage containers are complex, require multiple parts, and fail to ensure gas-tight sealing under internal pressures up to 6.2 bar, complicating recycling and consumer use.
Innovation Solution
A simplified closure assembly with a lid element and a closure element comprising a base part, lever, and cover, connected via pivot axes and a guide device, allowing for repeatable gas-tight sealing by pivoting the lever to open and close the opening, with components connected via rotation axes and a hinge for minimal parts and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex components and processes are used in resealable closure assemblies, then gas-tight sealing under internal pressure is achieved, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines the closure element and lid element into a single integrated closure assembly that is non-removably arranged on the lid element. This merging of components simplifies the overall structure while maintaining gas-tight sealing capability under internal pressures up to 6.2 bar, eliminating the need for complex separate components.
Solution Approach 2:
The closure assembly is designed to perform multiple functions: it provides initial sealing, enables repeated resealing, maintains gas-tight closure under pressure, and allows for captive arrangement on the beverage container. This multi-functionality reduces the need for additional specialized components, thereby simplifying the overall device complexity.
2Reliability
If multiple parts are used in closure assemblies, then gas-tight sealing is achieved, but weight increases and logistics become more complex
Solution Approach 1:
The closure element is non-removably arranged on the lid element, effectively merging two components into one integrated unit. This reduces the total number of parts, decreases weight, and simplifies logistics handling while maintaining the gas-tight sealing function required for beverage containers under pressure.
3Reliability
If complex processes are used for opening and closing, then reliable sealing is achieved, but ease of operation decreases
Solution Approach 1:
The closure assembly is designed with a self-sealing mechanism where the closure element automatically maintains gas-tight closure through its integrated structure on the lid element. The lever mechanism provides automatic positioning and sealing action, reducing the need for complex manual operations while ensuring reliable sealing each time the container is opened and closed.
4Ease of manufacture
If captive arrangement is implemented, then recycling is simplified, but manufacturing precision requirements increase
Solution Approach 1:
The closure element is non-removably arranged on the lid element, creating a captive arrangement that simplifies recycling by keeping all components together as a single unit. The integrated design with the lever mechanism provides self-positioning features that maintain manufacturing precision through geometric constraints rather than requiring additional precision fastening operations.
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 provides a lightweight, easy-to-use, and cost-effective closure that maintains gas-tight sealing even after initial opening, facilitating recycling and simplifying logistics with minimal components.
Implementation Method 1
The lever (11) is connected to the frame part (13) exclusively via a first axis of rotation (15) (and so as to be pivotable about this)
Implementation Method 2
The lid (12) is connected to the frame part (13) exclusively via a second axis of rotation (17) (and so as to be pivotable about this) or via a hinge
