Packaging Blank With Inward Protrusions For Cylindrical Article Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging methods for cylindrical objects, such as candles, are inefficient, wasteful, and time-consuming, as they do not conform to the shape of the product and often require excessive material.
Innovation Solution
A blank packaging configuration that can be wrapped around the article to form a circumferential case with inward protrusions at both ends, allowing for secure retention without the need for additional adhesives, and featuring a polygonal tube shape with latches and receivers for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional packaging methods are used for cylindrical objects, then the packaging can be easily manufactured, but the packaging does not conform to the shape of the product and uses excessive material
Solution Approach 1:
The packaging blank is divided into multiple panels (first panel, second panel, third panel, fourth panel) that can be folded along hinge lines to form a circumferential case. This segmentation allows the packaging to conform to the cylindrical shape of the product while using minimal material, eliminating the need for excessive packaging material used in conventional methods.
Solution Approach 2:
The packaging transitions from a flat two-dimensional blank to a three-dimensional circumferential case through folding along hinge lines. This dimensional transformation allows the packaging to wrap around and conform to the cylindrical shape of the product, achieving better fit and reduced material waste.
2Productivity
If conventional packaging boxes filled with foam are used, then the product is protected, but the packaging is time-consuming to prepare and wasteful of material
Solution Approach 1:
The invention extracts and eliminates the need for separate foam filling material by integrating the protective function directly into the circumferential case structure. The case itself provides both containment and protection, removing the additional time-consuming step of adding foam packaging material.
Solution Approach 2:
The protective function and containment function are merged into a single circumferential case structure. The case provides both structural support for containment and protection for the product, eliminating the need for separate protective foam materials and simplifying the packaging process.
3Reliability
If a circumferential case with inward protrusions is formed, then the article is securely retained longitudinally, but the blank structure becomes more complex
Solution Approach 1:
The inward protrusions are pre-formed as integral parts of the blank structure during manufacturing, rather than being added separately during assembly. The blank is designed with pre-scored lines and pre-formed protrusion panels that automatically create the retention features when folded and assembled, ensuring secure article retention while maintaining manufacturing efficiency.
4Stability of the object's composition
If latches and receivers are added to the circumferential case, then the case stability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The closure mechanism is segmented into separate functional components: latches formed on one flap and corresponding receivers on the opposite flap. This segmentation allows each component to be independently formed and positioned on the blank, providing stable closure while maintaining manufacturing simplicity through modular design.

AI summary
A blank for a package configured to retain an article therein can be configured to be wrapped around the article to form a circumferential case around the article and have a longitudinal length longer than the article. The blank can be configured to define the circumferential case to include one or more inward protrusions at or near one or more ends of the circumferential case that is configured to extend into the circumferential case above and/or below the article to retain the article longitudinally.
