Paperboard Carrier with Rectangular Base and Rounded Top
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrap-around article carriers face difficulties in processing and filling due to the rounded shape of their base portion, requiring modifications to existing equipment and machinery.
Innovation Solution
A paperboard carrier design featuring a rounded top and rectangular bottom with dust flaps that overlap to form composite end panels, allowing for efficient folding and secure wrapping around cylindrical containers while maintaining structural integrity and visual access through viewing ports, thus avoiding the need for additional equipment modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the carrier has a rounded base portion to conform to cylindrical containers, then the carrier provides a snug fit and structural integrity, but existing equipment and machinery require modifications to process and fill the carriers
Solution Approach 1:
The carrier is divided into distinct geometric zones: a rectangular base portion for easy handling and processing by existing equipment, and a rounded upper portion that conforms to the cylindrical containers. This segmentation allows the carrier to satisfy both the snug fit requirement and the ease of manufacture requirement without compromising either function.
2Strength
If the carrier uses a rounded configuration to wrap tightly around containers, then the carrier provides secure holding and minimizes paperboard quantity, but processing and filling operations become more difficult
Solution Approach 1:
Different portions of the carrier are given different geometric properties optimized for their specific functions: the base portion is rectangular with straight edges and right angles to facilitate easy processing and filling by existing equipment, while the upper portion is rounded to provide tight wrapping around the cylindrical containers and minimize paperboard usage. This local differentiation of geometric quality resolves the contradiction between wrapping strength and ease of manufacture.

AI summary
A carrier is constructed from paperboard and includes a rounded or non-rectangular top in combination with a non-rounded or rectangular bottom. Dust flaps which extend from the top and bottom of the carrier overlap one another to form a pair of opposing composite side panels. The dust flaps which are attached to the side panels include a crease or fold line adjacent to the bottom of the carrier which only extends partially along the height of the carrier so that the juncture between the side flap and the associated side panel adjacent the top of the carrier does not include a crease or fold line. As such, the side panel and adjacent side flap adjacent the top of the carrier can be tightly wrapped around the arcuate sidewall of the containers within the carrier to thereby provide a neat and tightly packed package configuration.
