Reinforced Weakness Lines in Self-Formed Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shelf ready packaging with lines of weakness often fails during transport and storage due to jostling, leading to internal damage and spillage of contents, compromising the entire transportable unit.
Innovation Solution
A self-reinforced container assembly with strategically positioned lines of weakness that are reinforced by the package's construction, allowing for stackable and transportable units with minimal tear (<10%) even under intense forces, using a single blank to form a package with internal reinforcement without external materials like tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lines of weakness are provided for ease of access to contents, then ease of operation is improved, but reliability deteriorates due to fracture during transport and storage
Solution Approach 1:
The patent applies local quality by providing reinforcement specifically at the lines of weakness locations where fractures are most likely to occur during transport and storage. The reinforcement elements are strategically positioned only at these critical points rather than throughout the entire package, thereby maintaining ease of access while locally enhancing fracture resistance.
Solution Approach 2:
The patent implements beforehand cushioning by incorporating reinforcement elements at the lines of weakness before the package undergoes transport and storage. These reinforcements act as preventive measures that cushion the vulnerable lines against the forces they will encounter during handling and stacking, preventing fracture before it occurs.
2Ease of manufacture
If package construction is simplified for cost-effectiveness, then ease of manufacture is improved, but strength deteriorates under stacking and transport forces
Solution Approach 1:
The patent applies local quality by providing reinforcement specifically at the lines of weakness locations where fractures are most likely to occur during transport and storage. The reinforcement elements are strategically positioned only at these critical points rather than throughout the entire package, thereby maintaining ease of access while locally enhancing fracture resistance.
Solution Approach 2:
The package structure provides self-reinforcement through its own construction, where the reinforcement elements are integrated into the package design itself rather than requiring separate external strengthening measures. This self-service approach maintains cost-effectiveness while achieving the necessary strength.
3Productivity
If articles are displayed directly from outer case, then productivity is improved, but device complexity increases due to reinforced construction
Solution Approach 1:

AI summary
The present invention is a package having strengthened, reinforced lines of weakness. More particularly, the package, in its fully formed configuration, provides for a self-reinforced package and strengthened, reinforced lines of weakness for stacking and transport wherein the package is resistant to fracture at its lines of weakness due to jostling of its contents against the inside of the package and at its lines of weakness.
