Hermetic Container Seal with Reinforced Frame and Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers with hermetic seals face challenges in ensuring a perfect seal, especially after damage or tampering, and require cost-effective and easy production methods while maintaining reliability.
Innovation Solution
A container design featuring a reinforced frame with a closing assembly comprising a plastic adapter and metal plug, where the adapter has a tear-off portion and grasping device to ensure secure sealing and easy access, utilizing a snap-fitting mechanism and a pusher element for alignment, and a lower annular sealing appendix for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple press-fitted closing assembly is used, then ease of manufacture and assembly is improved, but reliability of the seal against damage and tampering deteriorates
Solution Approach 1:
The closing assembly is divided into multiple functional components: a closing element with sealing唇, a cage structure with positioning elements, and a press-fitting mechanism. This segmentation allows each component to perform its specific function while maintaining overall simplicity and reliability
Solution Approach 2:
The cage structure pre-positions the closing element and sealing components before final assembly with the container. The positioning elements are pre-configured to ensure proper alignment and seal integrity, preventing tampering before the container is sealed
2Reliability
If a secure seal mechanism is implemented to prevent tampering, then reliability of the seal is improved, but device complexity increases
Solution Approach 1:
The closing assembly incorporates self-aligning and self-sealing mechanisms. The positioning elements automatically guide the closing element into the correct position, and the sealing唇 automatically engages with the container opening, eliminating the need for complex alignment procedures or additional fastening mechanisms
Solution Approach 2:
The closing element is nested within the cage structure, which itself is positioned within the container opening. This nested arrangement compactly integrates multiple protective and sealing functions without increasing external dimensions or requiring additional separate components
3Reliability
If a reinforced frame and multi-component closing assembly are used, then reliability of the seal is improved, but ease of manufacture deteriorates
Solution Approach 1:
The design utilizes material property changes and geometric parameter optimizations to achieve high reliability with simple manufacturing. The sealing唇 material is selected for its elastic recovery properties, and the cage geometry is optimized for snap-fit assembly, allowing reliable seals to be formed through material deformation rather than complex fastening operations
