Recyclable Coffee Package Strip Flange Linking Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional manufacturing methods for paper-based coffee packages result in pleats and are not suitable for producing recyclable, biodegradable, or compostable strips, which are essential for protecting coffee from air oxidation and mechanical stress while ensuring easy dispensing into coffee machines.
Innovation Solution
A method involving the precise positioning and linking of shells with flanges to form cavities, using recyclable and compostable materials like laminated paper, which are oxygen and moisture impervious, to create a strip of packages that can be sealed airtight and easily assembled, reducing pleats and enhancing dispensing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional embossing or thermoforming methods are used to manufacture paper-based packages, then the packages can be formed with cavities to hold beverage portions, but pleats appear around stamped portions and the manufacturing process is not suitable for recyclable materials
Solution Approach 1:
The manufacturing process is divided into separate sequential steps: first forming the cavity shape, then stamping the portion, and finally sealing the package. This segmentation avoids the need for simultaneous embossing and forming that causes pleats, allowing each operation to be optimized independently for recyclable paper-based materials.
Solution Approach 2:
The cavity shape is formed in advance before the portion is stamped into place. This preliminary action creates a pre-formed receptacle that can then be filled and sealed without the mechanical stress that causes pleating, enabling the use of recyclable materials that would be damaged by traditional simultaneous forming and stamping methods.
2Adaptability or versatility
If packages are made of recyclable paper-based material, then environmental sustainability is improved, but traditional manufacturing methods cause pleats and are not satisfying for production
Solution Approach 1:
The manufacturing parameters are changed to accommodate recyclable paper-based materials. The process uses lower temperatures and pressures compared to traditional thermoforming, and the sequential operations (forming, stamping, sealing) are optimized for the mechanical properties of paper, eliminating pleats while maintaining package quality and enabling recyclability.
3Ease of operation
If shells are positioned with overlapping flanges and linked together, then package assembly is simplified and dispensing efficiency is enhanced, but the positioning precision requirement increases
Solution Approach 1:
The flange acts as an intermediary element between adjacent shells. The overlapping flange design creates a mechanical interface that guides and maintains proper positioning during assembly. This intermediary structure simplifies the linking process and enhances dispensing efficiency by creating a stable, easily assembled package strip configuration.
