Packaging Container Segmentation for Stable Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid packaging paper containers face issues with unstable sealing due to easily peelable tape-shaped films and inability to disassemble paper containers without damaging the spout.
Innovation Solution
A packaging container design featuring a sheet material folded into a box shape with linearly formed weakened portions, allowing for compression, folding, and partial breaking to facilitate stable disassembly, including a spout plug with a cap for pouring and easy separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an easily peelable tape-shaped film is added to enable disassembly, then ease of operation is improved, but device complexity increases and sealing reliability deteriorates
Solution Approach 1:
The container body is divided into separable sections by forming weakened portions at specific locations. These weakened portions create predetermined break lines that allow the container to be divided into manageable segments for recycling, eliminating the need for additional peelable films or tabs.
Solution Approach 2:
The weakened portions are formed during the manufacturing process, creating pre-designed fracture paths before the container reaches the consumer. This preliminary preparation enables easy disassembly by the end user without requiring complex mechanisms or additional components.
2Ease of operation
If a weakened portion is added to facilitate breaking, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The weakened portions are created with localized structural modifications at specific locations on the container body. By concentrating the structural change to specific areas rather than uniformly modifying the entire container, the design achieves easy disassembly while maintaining overall manufacturing feasibility and precision standards.
3Productivity
If the container is designed for easy disassembly, then productivity of recycling is improved, but sealing reliability may deteriorate
Solution Approach 1:
The container is designed with weakened portions that create natural separation points, allowing the container to be divided into segments for recycling. This segmentation enables efficient disassembly without compromising the integrity of the sealing portions during normal use.
Solution Approach 2:
The structural modifications are localized to specific weakened portions rather than affecting the entire container structure. This localized approach allows the container to maintain its sealing reliability in critical areas while enabling easy disassembly at predetermined locations for recycling purposes.

AI summary
A packaging container formed by folding a sheet material and includes a container body that has a trunk, a top and a bottom. The trunk serves as side panels, while the top and the bottom are respectively connected to ends of the trunk. In the packaging container, a first weakened portion is linearly formed in the container body.
