Carton End Closure Panels for Secure Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wraparound type cartons lack effective security features to prevent theft and ensure secure packaging of articles, and there is a need for improved means to close the ends of the carton.
Innovation Solution
A carton design featuring a tubular structure with end panels that include upper and lower end closure panels hingedly connected to side wall panels, secured by connecting panels and optionally frangible connections, along with a top end flap that can be secured using adhesive, facilitating secure closure and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If end closure panels and securing panels are added to close the ends of the carton, then security against theft is improved, but device complexity increases
Solution Approach 1:
The end closure structure is divided into multiple functional panels: lower end closure panels hinged to side walls, upper end closure panels, and securing panels with frangible connections. This segmentation allows each panel to perform a specific function (closure, sealing, security) while maintaining overall system manageability and assembly ease despite the increased number of components.
2Reliability
If multiple panels and frangible connections are used to secure the carton ends, then security is improved, but manufacturing complexity increases
Solution Approach 1:
The frangible connections are pre-formed during the cartoning process, and the end closure panels are pre-hinged to the side wall panels. This preliminary preparation of connection points and hinges allows for rapid assembly and secure closure without requiring complex manual operations or additional manufacturing steps, thereby maintaining ease of manufacture despite the enhanced security features.
3Reliability
If upper end closure panels are coupled to lower end closure panels and securing panels, then security is improved, but the number of components increases
Solution Approach 1:
The upper end closure panels are coupled to both the lower end closure panels and the securing panels, creating an integrated end closure assembly. This merging of multiple panels into a unified structure that works together provides enhanced security through multiple interconnected closing mechanisms, while the coordinated design reduces the functional complexity compared to having separate independent closure systems.

AI summary
A carton for packaging a plurality of articles includes top (214, 314) and bottom (218/220, 318/320) panels connected together by spaced side wall panels thereby forming a tubular structure and a set of end panels for at least partially closing each end of the tubular structure. Each set of end panels includes a pair of upper end closure panels (232a, 232b, 332a, 332b), a pair of lower end closure panels (226a, 226b, 326a, 326b) hinged to respective lower portions of the side wall panels respectively and a pair of securing panels (224a, 224b, 324a, 324b) hingedly connected to respective upper portions of the side wall panels respectively. The upper end closure panels (232a, 232b, 332a, 332b) are hingedly connected respectively to the securing panels by respective connecting panels (230a, 230b, 340a, 340b). The upper end closure panels are coupled to the lower end closure panels respectively.
