Container Lid Closure With Wing Lever for Air-Evacuation Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container designs lack efficient sealing mechanisms that create tight seals, effectively expel air, and prioritize user experience, often requiring separate operations for closure and gas channeling, leading to frustration and reduced product freshness.
Innovation Solution
A closure means integrating a lid assembly with a wing member and sealing element that allows for simultaneous air evacuation and sealing, featuring a levering effect for easy operation and secure attachment, with optional gas channeling means for independent air flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional closure mechanisms are used, then the container can be closed, but the sealing is not tight and air pockets remain inside
Solution Approach 1:
The patent applies preliminary action by providing a gas channeling means that is activated before the final sealing occurs. The closure means includes a gas channeling means with a valve that opens to allow gas evacuation before the sealing element makes final contact with the container opening, ensuring air pockets are removed prior to sealing.
Solution Approach 2:
The patent uses an intermediary mechanism by introducing a gas channeling means as an intermediate step between the closure operation and the sealing operation. The valve and gas channel act as intermediaries to facilitate controlled gas evacuation before the sealing element completes the sealing process.
2Adaptability or versatility
If separate closure and gas channeling means are used, then each function can be performed, but the operation becomes complex and frustrating
Solution Approach 1:
The patent merges the closure means and gas channeling means into a single integrated assembly. The closure means includes both the sealing element and the gas channeling means with valve, allowing both sealing and gas evacuation functions to be performed through a single operational sequence without requiring separate operations.
Solution Approach 2:
The patent implements multi-functionality by designing the closure means to perform multiple functions: sealing the container opening and evacuating gas through the same assembly. The valve can be opened and closed during the sealing process, enabling the single device to handle both gas evacuation and sealing operations.
3Reliability
If the closure means requires excessive force to operate, then the sealing can be secure, but user experience deteriorates
Solution Approach 1:
The patent applies dynamics by making the valve operable in a dynamic manner during the sealing process. The valve can be opened and closed at different stages of the sealing operation, allowing the system to adapt the required force dynamically - less force for gas evacuation phase and secure sealing for the final phase.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining the valve in an open state during the gas evacuation phase and then transitioning to closed state for sealing, without requiring the user to re-apply force. The valve mechanism continues the sealing action smoothly from gas evacuation to final sealing.

Function Achieved in This Case
Ensures airtight sealing, preserves freshness, and enhances user convenience by simplifying the sealing process while preventing accidental detachment, with optional gas channeling for controlled air exchange.
Implementation Method 1
at least one wing member comprising a handling portion, a flipping portion, and a stopper portion, said wing member pivotably connecting to said lid cover at said hinge member and thus movable between a first position where said stopper portion being away from said upper plate of said lid cover and a second position where said stopper portion being engaged with said upper plate of said lid cover
Implementation Method 2
a sealing element, fittingly mounted around said standing wall of said lid cover

AI summary
The present invention relates to a closure means for closing the opening of a container, said closure means comprising: a) a lid assembly, comprising: a lid cover, configured to provide an upper plate and a lower plate connecting said upper plate via standing wall therebetween, said upper plate is provided with at least one hinge member; at least one wing member comprising a handling portion, a flipping portion, and a stopper portion, said wing member pivotably connecting to said lid cover at said hinge member and thus movable between a first position where said stopper portion being away from said upper plate of said lid cover and a second position where said stopper portion being engaged with said upper plate of said lid cover and thus the upward movement of said wing member with respect to said lid cover being limited; and b) a sealing element, fittingly mounted around said standing wall of said lid cover; and characterized in that, in a first configuration where said container being closed with said closure means, said wing member being moved from said first position to said second position causing said closure means being moved upwards automatically.
