Packaging Blank Pretreatment for Lower-Force Beverage Can Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for beverage containers require high energy input, material costs, and generate waste due to the use of shrink films, while top gripping type cartons necessitate high application forces that can damage articles.
Innovation Solution
A packaging apparatus and method that uses a pre-treatment module to reduce the resistance force in the edge areas of packaging blanks, allowing for easier application to articles by enlarging passage openings with stretching dies, securing tabs, and optional secondary packaging methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If top gripping type cartons are used to gather articles, then articles can be securely held together, but high application forces are required that can damage the articles
Solution Approach 1:
The patent applies preliminary action by pre-treating the packaging blank before application to articles. The pre-treatment module enlarges passage openings and reduces resistance forces in advance, so that when the packaging blank is subsequently applied to articles, the required application force is significantly reduced, preventing damage while maintaining secure holding.
Solution Approach 2:
The patent changes physical parameters of the packaging blank through pre-treatment. The resistance force in edge areas is reduced and passage openings are enlarged, transforming the packaging blank from a high-resistance state to a low-resistance state that requires minimal application force while still providing reliable article holding.
2Reliability
If shrink films are used to package beverage containers, then containers can be gathered into packs, but high energy input and material costs are required while generating waste
Solution Approach 1:
The patent extracts and eliminates the shrink film from the packaging system. Instead of using shrink films that require high energy input for heating and shrinking, the invention uses a pre-treated packaging blank that can be applied with minimal force, thereby removing the energy-intensive shrinking process while maintaining packaging functionality.
Solution Approach 2:
The patent replaces expensive, energy-intensive shrink films with a simpler, less resource-consuming packaging blank. The pre-treated blank requires minimal processing energy and can be applied directly, reducing both energy input and material costs while avoiding waste generation from film shrinkage processes.
3Reliability
If passage openings in packaging blanks are made smaller to fit articles, then articles can be securely held, but high application forces are required to push articles through
Solution Approach 1:
The patent applies preliminary action by pre-treating the packaging blank to enlarge passage openings before article application. This preliminary enlargement reduces the force barrier that would otherwise be required to push articles through, allowing secure holding with minimal application force.
Solution Approach 2:
The patent applies preliminary anti-action by pre-reducing the resistance force in edge areas of passage openings. This preliminary reduction counteracts the potential harm of high application forces, allowing the packaging blank to maintain secure holding capability while requiring minimal force during article application.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
