Integrated Container Closure for Air Evacuation and Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container designs lack efficient sealing mechanisms that create tight seals, expel air effectively, 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 gas channeling mechanism, featuring a lid cover, wing members, and a sealing element, allowing for simultaneous air evacuation and sealing through a biased/unbiased transition of the wing member, ensuring airtight environments and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional separate closure means and gas channeling means are used, then device complexity is reduced, but ease of operation deteriorates due to requiring separate operations
Solution Approach 1:
The patent combines the closure means and gas channeling means into a single integrated closure device. The closure means includes both a closure element for sealing the container opening and a gas channeling element integrated within the same device, allowing simultaneous sealing and gas evacuation functions to be performed by one operational action rather than separate operations.
Solution Approach 2:
The integrated closure device performs multiple functions simultaneously: it provides mechanical closure/sealing of the container opening through the closure element, and it provides gas channeling/evacuation through the gas channeling element. This multi-functional design eliminates the need for separate closure and gas channeling operations, improving ease of use.
2Reliability
If conventional sealing mechanisms are used, then device complexity is reduced, but reliability deteriorates due to inability to create tight seals and expel air effectively
Solution Approach 1:
The patent integrates both sealing and gas evacuation functions into a single closure device, ensuring that the sealing operation and gas expulsion operation occur simultaneously and cooperatively. This integration ensures that air pockets are effectively removed while creating a tight seal, improving reliability of the sealing process.
Solution Approach 2:
The gas channeling element is designed to evacuate gas from the container before the final sealing is completed. This preliminary gas removal action ensures that air pockets are eliminated prior to the sealing element making full contact, preventing trapped air that would compromise seal integrity and product freshness.
3Productivity
If repeated sealing operations are performed, then productivity is improved, but loss of substance increases due to air pockets remaining in container
Solution Approach 1:
The gas channeling element performs preliminary gas evacuation before sealing is completed, removing air pockets from the container. This preliminary action prevents product exposure to air during storage and transport, maintaining product freshness and preventing quality degradation over repeated use cycles.
Solution Approach 2:
The integrated design ensures continuous gas evacuation throughout the sealing process, maintaining a consistent seal quality across repeated opening and closing operations. The gas channeling remains active during the entire sealing sequence, ensuring air pockets are continuously removed, which preserves product integrity over multiple use cycles.

AI summary
A closure means for closing an opening of a container includes a lid assembly having a lid cover, configured to provide an upper plate and a lower plate connecting the upper plate via a standing wall. The upper plate has at least one hinge member. A wing member includes a handling portion, a flipping portion, and a stopper portion. The wing member pivotably connects to the lid cover at the hinge member and moves between a first position and a second position. The upward movement of the wing member is limited. A gas channeling means having a first configuration where the container is closed with the closure means. The gas channeling means is biased. The wing member moves from the first position to the second position causing the closure means being moved upwards automatically and causing the gas channeling means transiting from a biased condition to an unbiased condition.
