Beverage Can Closure Insert With Locking Reclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage cans cannot be resealed after opening, leading to risks of spilling, contamination, and insect entry, and existing solutions fail to provide a cost-effective and reliable method for easy opening and resealing.
Innovation Solution
A beverage can closure element featuring a frame part with a cover element and locking device that can be easily locked and unlocked, using a clamped, adhesive, or injection-molded connection, with perforation lines for separation and a bearing device for secure actuation, allowing for easy reclosure and re-opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional beverage can is opened, then the beverage can be accessed, but the can cannot be resealed leading to spillage and contamination risks
Solution Approach 1:
The closure element is inserted into the opening of the beverage can, with the cover element nesting within the frame part. The closure element acts as a nested structure that fits into the can opening, providing a compact resealing solution that maintains reliability while enabling easy operation.
Solution Approach 2:
The closure element is divided into two main segments: the frame part and the cover element. These segments can be separately manufactured and connected through various methods (clamping, adhesive, or injection molding), allowing for cost-effective production while maintaining the reliability of the resealing function.
2Ease of manufacture
If a closure element with multiple connection methods is used, then manufacturing flexibility is improved, but device complexity increases
Solution Approach 1:
The patent provides different connection methods (clamping, adhesive, injection molding) as alternative parameter options for manufacturing. This allows manufacturers to select the most appropriate method based on specific production requirements, maintaining ease of manufacture without necessarily increasing device complexity, as only one connection method is implemented per product.
3Reliability
If a locking device is added to secure the cover element, then reliability of sealing is improved, but ease of operation for opening and closing is reduced
Solution Approach 1:
The locking device is designed to be dynamic rather than static, allowing it to engage and disengage easily. The bearing device provides a pivot point that enables the cover element to rotate and lock into place during closing, and to be easily opened by applying force to overcome the locking mechanism. This dynamic design maintains sealing security while preserving ease of operation.
4Ease of manufacture
If the cover element is completely separated from the frame, then ease of manufacture is improved, but structural stability and sealing reliability worsen
Solution Approach 1:
The closure element is segmented into a frame part and a cover element that can be separately manufactured, improving ease of manufacture. However, these segments are connected through secure connection methods (clamping, adhesive, or injection molding) that maintain structural stability and sealing reliability when assembled.
Solution Approach 2:
The connection between the frame part and cover element may involve composite construction techniques, combining different materials and connection methods to achieve both ease of manufacture and reliable sealing. The composite approach allows each component to be optimized for its specific function while maintaining overall structural integrity.
