Separable Container Cap Structure for Easier Plastic Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container caps with separable use traces, such as plastic belts, are difficult to recycle and cumbersome to separate, contributing to environmental pollution and waste management issues.
Innovation Solution
A container cap design featuring a body part, cover part, and a separation part connected by first and second connection parts, allowing for easy separation and integration of components for recycling, with a fixing part to secure the separation part after use, and a hinge for easy opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a use trace belt is used to allow the cover part to open and close, then the container cap can be sealed and opened, but the separation operation becomes cumbersome and recycling becomes difficult
Solution Approach 1:
The container cap is divided into separable components: a body part and a cover part connected by a hinge, with a use trace belt that can be easily separated. This segmentation allows the cover part to be detached from the body part after use, simplifying the separation operation and enabling recycling of individual components.
Solution Approach 2:
The use trace belt is extracted as a separate, removable component from the container cap assembly. It is coupled to both the body part and cover part but can be easily separated from both, allowing it to be removed and recycled independently without complicating the separation process.
2Ease of manufacture
If the use trace belt is formed together with the container cap by plastic injection molding, then manufacturing is simplified, but recycling becomes difficult as the belt cannot be separated
Solution Approach 1:
The container cap is designed with separable components (body part and cover part) that can be easily separated from each other and from the use trace belt. This segmentation maintains manufacturing simplicity through integrated molding while enabling recyclability by allowing individual components to be separated and reused or recycled.
Solution Approach 2:
The use trace belt is designed to be easily separable from both the body part and cover part, allowing it to be discarded or recovered for recycling after use. This enables the recovery of plastic materials through separation of the belt from the main container cap structure.
3Loss of substance
If the use trace belt is separated from the container cap, then recycling becomes possible, but the separation operation becomes more complex
Solution Approach 1:
The container cap assembly is segmented into distinct separable components: body part, cover part, and use trace belt. Each component can be separated from the others through simple operations, making the separation process straightforward while enabling recyclability of individual components.
Solution Approach 2:
The use trace belt is extracted as an easily separable component from the container cap assembly. It can be removed from both the body part and cover part through simple separation operations, making the recycling process straightforward without adding complexity to the separation procedure.
