Rotating Locking Ring Lid for Resealing Beverage Cans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Canned beverages pose a challenge due to their sealing manner, requiring immediate consumption after opening and being difficult to carry due to leakage and potential deformation of the container.
Innovation Solution
A container lid design featuring a lid body with elastic locking strips and a rotating locking ring with protrusions that engage with the lid body to securely fasten onto the container, allowing for resealing without applying external pressure, thereby preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional sealed can is used, then the beverage can be stored and transported, but it requires immediate consumption after opening and cannot be resealed
Solution Approach 1:
The lid is divided into separate functional components: a lid body with elastic locking strips and a rotating locking ring with locking protrusions. This segmentation allows the sealing function to be independent from the opening function, enabling resealing while maintaining simple structure.
Solution Approach 2:
The locking ring can rotate relative to the lid body, transitioning between locked and unlocked positions. The elastic locking strips dynamically deform to engage or disengage with the locking protrusions, providing reversible sealing without complex mechanisms.
2Reliability
If external pressure is applied to fasten the lid tightly, then the sealing effect is improved, but the container body deforms
Solution Approach 1:
The elastic locking strips are positioned at specific locations around the lid periphery and only apply localized clamping forces at these discrete points rather than uniform pressure. This localized engagement achieves effective sealing while avoiding deformation of the container body.
Solution Approach 2:
The elastic locking strips utilize elastic deformation to provide sufficient clamping force for sealing without requiring excessive external pressure. The material parameter of elasticity allows the strips to flex and engage with the locking protrusions, achieving reliable sealing at low force levels that prevent container deformation.
3Ease of operation
If the lid is designed to be easily opened and closed, then the operation convenience is improved, but the sealing reliability may be compromised
Solution Approach 1:
The rotating locking ring provides dynamic operation: rotating the ring unlocks the elastic locking strips from the locking protrusions, allowing easy opening. Rotating to the locked position re-engages the strips, providing reliable sealing. This dynamic mechanism achieves both ease of operation and sealing reliability.
Solution Approach 2:
The elastic locking strips automatically engage with the locking protrusions when the locking ring is rotated to the locked position, without requiring additional fastening actions. The elastic deformation of the strips provides self-latching functionality that ensures reliable sealing while maintaining simple operation.

Function Achieved in This Case
The lid effectively reseals the container, enabling repeated use and preventing deformation, while providing convenience for carrying and drinking.
Implementation Method 1
the at least one elastic locking strip is configured to undergo elastic deformation toward an inside of the lid body under an external force

AI summary
The present disclosure provides a container lid, including a lid body and a locking ring. The lid body has a peripheral outer wall, on which at least one elastic locking strip is arranged, and each elastic locking strip undergoes elastic deformation toward an inside of the lid body. The peripheral inner wall of the locking ring container rotates coaxially along the peripheral outer wall, and a locking protrusion is arranged on the peripheral inner wall corresponding to each elastic locking strip. When the locking ring rotates to a preset angle relative to the lid body, the elastic locking strip fastens the top of the container body with elastic deformation.
