Solution Overview
Problem
Existing silicone spring products for container lids are complex to manufacture, resulting in high scrap material rates and increased costs, while also being less efficient in terms of ease of integration and cost-effectiveness.
Innovation Solution
A silicone extruded spring strap that can be folded and stretched, eliminating the need for complex shaping and reducing material waste, combined with a spring strap clip for secure attachment to a closure system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional T-form silicone springs are used, then the spring function is performed well, but the manufacturing complexity increases and scrap material rate increases
Solution Approach 1:
The spring function is segmented from the lid structure itself. Instead of using a separate complex T-form spring component, the patent integrates the spring function into a simple extruded strap that is part of the lid assembly, reducing overall device complexity while maintaining the spring function.
Solution Approach 2:
The patent uses a simple extruded strap design that can be easily manufactured and replaced if needed. This simpler component design reduces manufacturing complexity and allows for easier integration compared to complex molded T-form springs.
2Reliability
If traditional T-form silicone springs are used, then the spring function is performed well, but the scrap material rate increases
Solution Approach 1:
The patent changes the manufacturing parameters from complex punching and molding operations to simple extrusion and cutting. The extruded strap is cut to the required length during manufacturing, resulting in minimal scrap material compared to the punching process required for T-form springs.
Solution Approach 2:
The spring function is segmented from the lid structure itself. Instead of using a separate complex T-form spring component, the patent integrates the spring function into a simple extruded strap that is part of the lid assembly, reducing overall device complexity while maintaining the spring function.
3Reliability
If complex shaped silicone springs are molded, then the spring function is achieved, but the manufacturing process requires specific complex steps and assembly
Solution Approach 1:
The patent merges the spring function with the lid structure by using an extruded strap that is integrated into the lid assembly. This eliminates the need for separate complex spring components and simplifies the manufacturing and assembly process.
Solution Approach 2:
The extruded strap serves multiple functions: it provides the spring function for the pop-up lid, acts as a structural component of the lid assembly, and can be easily manufactured through standard extrusion processes. This multi-functionality reduces the need for specialized components and complex assembly steps.
Applied Scientific Principles

Function Achieved in This Case
The solution allows for quick production with minimal scrap, reduces manufacturing complexity, and provides a cost-effective, efficient self-opening and re-closable lid system with improved air sealing capabilities.
Implementation Method 1
The extruded spring strap can store and release energy in order to displace the lid
Implementation Method 2
creating the compression and release like one found on a metallic coil spring

AI summary
An extruded spring strap that has the possibility to be folded around an axis parallel to its own axis of extrusion, creating the compression and release as of a spring. A base has a reach-in hole on its body. The lid is the base's capping object; it is designed to cover the reach-in hole. A spring strap clip allows the extension of the spring strap during the closing motion of the lid. The spring strap and the spring strap clip assembled to the lid and base. An area of hot melt fills a cavity on the spring clip ensuring proper position for the spring clip during usage and no disassembly. The extruded spring strap can store and release energy in order to displace the lid. The retention latch is the user interface on which he acts in order to have the lid pop-up.
