Innovation Solution
A system for regenerating and recycling packaging includes a cap separation unit using blades and guide notches, a label processing unit, and a deposit/collection unit with sensors and pneumatic mechanisms to separate and collect compatible packages, enabling efficient recycling and reuse of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packaging materials are designed for high performance and durability, then protection and functionality are improved, but recyclability and ease of separation deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the packaging system into separable components: the container body and the closure cap. The closure is designed with a breakable seal that can be cleanly separated from the container through the blade mechanism, allowing each component to be recycled independently according to its material type, thus resolving the contradiction between maintaining high-performance sealed packaging and enabling easy recycling separation.
2Adaptability or versatility
If complex multi-material packaging is used to improve functionality, then performance is enhanced, but separation and recycling difficulty increase
Solution Approach 1:
The patent extracts the sealing function into a separate breakable seal component that is distinct from both the container and the closure cap. This extracted seal can be cleanly removed and separated through the blade mechanism, allowing the container and cap to be recycled separately without the contamination and complexity that would arise from attempting to separate multiple bonded materials, thus reducing material separation complexity while maintaining functional performance.
3Loss of substance
If traditional recycling methods like grinding are used, then material recovery is achieved, but quality loss and environmental impact increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring the packaging with a breakable seal designed to be cleanly separated before recycling processing. This preliminary separation of components eliminates the need for grinding and extensive mechanical processing, allowing materials to be directly recycled in their original form, thereby preventing quality loss and reducing environmental impact from energy-intensive processing operations.
4Duration of action of stationary object
If packaging is designed for reuse cycles, then sustainability is improved, but material compatibility and deterioration resistance requirements increase
Solution Approach 1:
The patent applies local quality by designing the breakable seal with specific material properties localized at the separation point. The seal is engineered to be cleanly separable while the container and cap maintain their respective material integrity for reuse. This localized design ensures material compatibility is maintained for multiple reuse cycles while enabling easy separation when recycling is required, thus resolving the contradiction between reuse durability and material compatibility requirements.

AI summary
The invention relates to a system for the regeneration and/or advanced recycling of packagings of the type comprising an elongated neck like a bottle and a cap anchored to the neck of the packaging by means of a sealing ring held in place and made efficient by a pair of longitudinally spaced annular projections. The system comprises a conveying unit for the packages to be treated towards a separation unit for separating the cap from the packaging and a collecting unit for the caps separated from the packaging. The separation unit for the cap comprises at least one blade, preferably two opposing blades, for cutting the sealing ring, said blade(s) being configured to cut the sealing ring at a predefined position of the neck of the packaging, said predefined position being identified by oriented guide notches provided on the packagings to be treated on at least one of the two annular projections and generally both.The invention also relates to a packaging and a deposit/collection unit particularly suitable for use in the aforesaid system.
