Resealable Beverage Can Lid With Repositionable Opening Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage cans cannot be resealed after opening, leading to carbonation loss, spoilage, spillage risks, and contamination, necessitating quick consumption and potential waste.
Innovation Solution
A resealable beverage can lid with a score line forming a panel, two rivets, and a tab portion that connects to both, allowing the panel to be completely freed and repositioned to close the lid, enabling multiple openings and closings without special tools or increased manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the beverage can is opened by rupturing the lid, then the beverage can be accessed and consumed, but the opening cannot be closed again leading to carbonation loss and spoilage
Solution Approach 1:
The lid is segmented into a fixed portion and a movable panel that can be completely detached from the can opening. The panel is connected via a hinge allowing it to swing between covering and removed positions, enabling the opening to be fully closed when not in use, thus preserving beverage carbonation and preventing spoilage.
Solution Approach 2:
The panel is designed to be dynamically movable rather than fixed. It can be completely removed from the opening for beverage consumption, then swung back via the hinge to fully cover and seal the opening, providing dynamic control over the beverage's exposure to air and contaminants.
2Ease of operation
If the panel is completely detached from the lid for opening, then the beverage can be fully accessed, but the panel may be lost or mispositioned
Solution Approach 1:
A hinge acts as an intermediary mechanism between the panel and the fixed lid portion. This hinge connection allows the panel to be completely detached from the opening for full beverage access, while simultaneously providing a retention mechanism that prevents the panel from being lost or mispositioned by allowing it to swing back to a closed position.
3Adaptability or versatility
If an opened beverage can is carried, then mobility is achieved, but spillage risk increases due to inability to close the opening
Solution Approach 1:
The panel's dynamic movement capability allows it to be completely removed when the beverage needs to be consumed, providing full access during portability. When not consuming, the panel swings back to fully cover the opening, ensuring beverage containment and preventing spillage during movement or accidental knocking.
4Reliability
If the lid structure is modified to allow complete panel removal, then resealability is achieved, but manufacturing complexity may increase
Solution Approach 1:
The lid is segmented into a fixed portion and a movable panel connected by a hinge, allowing complete panel removal for opening and full closure for resealing. This segmentation achieves resealability while using simple, conventional manufacturing techniques for forming metal panels and hinges, avoiding complex assembly processes.

AI summary
A resealable beverage can lid has a lid having a top side having a score line forming a panel, a first rivet formed in the lid and extending outwardly from the top side of the lid, a second rivet formed in the panel and extending outwardly from the top side of the lid, and a tab portion connected to the first rivet and the second rivet.
