Partitioned Article Carrier Blank for Low-Waste Heavy-Load Cartons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article carriers, such as cartons, require significant material usage and do not effectively secure contents, especially when transporting heavy loads, while also causing environmental waste.
Innovation Solution
A carrier design featuring a partition structure with hingedly connected lateral partition flaps and glue flaps, coupled by a distal end joint, allowing for easier folding and assembly, and incorporating tear stopper elements to prevent tearing during erection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional carton designs are used, then material usage is significant, but this causes environmental waste and increases cost
Solution Approach 1:
The partition panel is divided into multiple functional segments: a main body portion, a distal end joint connecting lateral partition flaps to a glue flap, and a tab interrupting the fold line. This segmentation allows each part to perform its specific function efficiently, reducing overall material usage while maintaining structural integrity through optimized distribution of material in critical areas.
Solution Approach 2:
The lateral partition flaps are nested within the partition panel structure, with the distal end joint integrating multiple components (lateral flaps, glue flap, and tab) into a compact interconnected assembly. This nesting approach minimizes material waste by eliminating redundant structures while preserving the strength needed for holding articles.
2Ease of operation
If traditional partition structures are used, then assembly is difficult on automated machinery, but the invention enables easier folding and assembly
Solution Approach 1:
The partition structure incorporates a tab that interrupts the fold line, creating a dynamic assembly mechanism. During erection, the tab interacts with the distal end joint to guide the folding process, enabling automated machinery to easily fold the partition panel without complex alignment procedures. The structure transitions from a flat blank to an erected configuration through controlled folding actions at the distal end joint.
Solution Approach 2:
The tab acts as an intermediary element between the fold line and the distal end joint, mediating the folding process. By interrupting the fold line and protruding into the partition panel, the tab provides a reference point and mechanical guide for automated assembly equipment, simplifying the erection process while the distal end joint provides the actual connection between lateral flaps and the glue flap.
3Reliability
If heavy loads are transported, then articles need secure holding, but traditional designs cause material waste
Solution Approach 1:
The partition structure applies local quality by concentrating material and structural complexity only where needed for strength and security. The distal end joint and tab provide localized reinforcement at critical connection points, while other areas use minimal material. This ensures reliable holding of heavy loads through strategically placed structural features rather than uniform material distribution throughout the entire partition.

AI summary
Aspects of the disclosure relate to an article carrier for packaging a plurality of articles, a blank for forming the article carrier. The article carrier comprises a plurality of primary panels for forming a tubular structure and defining an interior thereof. The plurality of primary panels includes a pair of opposed end panels. The article carrier further comprises a partition structure for dividing the interior into two or more article-receiving cells. A primary partition panel is hingedly connected to one of the pair of end panels along a first fold line, the primary partition panel comprises the partition structure. The partition structure comprises at least one lateral partition flap and a glue flap. The at least one lateral partition flap and the glue flap are coupled together by a distal end joint. The distal end joint is adjoined by a tab interrupting the first fold line. The tab protrudes from the end panel into the primary partition panel to be in close proximity or contact with the distal end joint.
