Elastomeric Sealing Bag with Lateral Compression Covering Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing bags with zippers often fail to maintain a reliable seal due to misalignment or deformation of zipper components, leading to leakage and spoilage of contents.
Innovation Solution
A sealing system featuring an elastomeric protruding component with a slit, combined with a covering assembly that includes a first and second interlocking portion, allowing the second covering portion to pivotally engage and drive the first covering portion to squeeze the elastomeric protruding component along a lateral direction, ensuring a secure seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional zipper is used for sealing, then the sealing bag can be opened and closed easily, but the sealing reliability deteriorates due to particle interference or deformation of zipper components
Solution Approach 1:
The sealing system is divided into separate components: an elastomeric protruding component with a slit and a covering assembly with first and second covering portions. This segmentation allows each component to perform its specific function independently, reducing the risk of mutual interference that plagues conventional zippers where male and female members must precisely align.
Solution Approach 2:
Instead of using interlocking teeth that must align perfectly (conventional zipper approach), the invention inverts the sealing mechanism by using a protruding elastomeric component that is covered and compressed. The sealing action is achieved by compressing the elastomeric material itself rather than by interlocking rigid components, fundamentally changing the sealing paradigm.
2Reliability
If zipper components are made robust to prevent deformation, then sealing reliability improves, but the device complexity increases due to additional protection mechanisms
Solution Approach 1:
The invention changes the material parameter from rigid (conventional zipper teeth) to elastomeric (protruding component). This parameter change allows the sealing component to be inherently more resistant to deformation while maintaining simplicity, as the elastomeric material can elastically deform and return to its original shape without permanent damage.
Solution Approach 2:
The elastomeric protruding component acts as an intermediary between the bag body and the covering assembly. It provides a compliant surface that can be compressed by the covering assembly to achieve sealing, eliminating the need for complex interlocking mechanisms while maintaining reliable sealing performance.
3Device complexity
If a simple covering structure is used, then device complexity is reduced, but sealing effectiveness deteriorates due to insufficient compression force
Solution Approach 1:
The covering assembly incorporates a pivotal connection between the first and second covering portions, allowing dynamic movement during the sealing process. When the second covering portion is rotated relative to the first, it drives the protruding component to squeeze along the lateral direction, creating the necessary compression force for effective sealing while maintaining structural simplicity.
Solution Approach 2:
The invention adds a lateral dimension to the sealing action. The protruding component is driven to squeeze not only in the protruding direction but also along the lateral direction perpendicular to it. This multi-directional compression enhances sealing effectiveness without requiring a complex multi-component system.

Function Achieved in This Case
This mechanism effectively prevents contents from entering or exiting the bag, enhancing the reliability and freshness of stored items by maintaining a tight seal.
Implementation Method 1
The elastomeric protruding component is disposed on the bag body and protrudes from the bag body along a protruding direction. The first covering portion is driven to squeeze the elastomeric protruding component along a lateral direction different from the protruding direction to seal the slit

AI summary
A sealing bag includes a bag body and a sealing system including an elastomeric protruding component and a covering assembly. The elastomeric protruding component is disposed on the bag body and protrudes from the bag body along a protruding direction. A slit penetrates through the elastomeric protruding component along the protruding direction and is communicated with an inner space of the bag body. The covering assembly includes a covering component including a first covering portion detachably installed on the elastomeric protruding component in a sliding manner, and a second covering portion pivotally connected to the first covering portion. The second covering portion drives the first covering portion to squeeze the elastomeric protruding component along a lateral direction different from the protruding direction to seal the slit when the first covering portion is installed on the elastomeric protruding component and the second covering portion pivotally engages with the first covering portion.
