Folded Corrugated Container Reinforced Quick-Locking Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated or paperboard containers used for transporting liquid wastes, including medical wastes, face issues with handle weakening due to twisting and bending forces, leading to potential leakage and contamination risks, especially when heavily loaded or handled roughly.
Innovation Solution
A foldable, corrugated container design with reinforced grasping regions and a secure, lockable lid, featuring bifurcated corner panels and anchoring holes for plastic handles, ensuring a ruggedized handle construction and leak-proof functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional handle constructions are used in corrugated containers, then the container is easy to manufacture and assemble, but the handles weaken and break down over time due to twisting and bending forces
Solution Approach 1:
The handle is merged with the container body by forming it from the same corrugated material through folding and sealing operations. The handle integrates with the container walls, creating a unified structure that eliminates the weakness of separate handle attachments and distributes mechanical stresses throughout the integrated structure.
Solution Approach 2:
The handle structure is segmented into multiple reinforced sections with distinct folding patterns and sealing locations. This segmentation allows each portion of the handle to be optimized for its specific functional requirements while maintaining overall structural integrity through the distributed folding and sealing architecture.
2Adaptability or versatility
If the container is designed to be foldable and collapsible for storage, then storage efficiency is improved, but the structural integrity during handling and transport is compromised
Solution Approach 1:
The container employs dynamic folding lines and collapsible panels that allow it to transition between expanded and collapsed states. The folding structure is designed to maintain structural integrity during handling in the expanded state while enabling compact storage when collapsed, with reinforced sections preserving strength throughout the transformation cycle.
Solution Approach 2:
The container includes pre-formed folding lines, score marks, and preliminary sealing structures that enable easy collapse and reassembly. These preliminary features are built into the container body during manufacturing, allowing rapid transition between storage and operational states without compromising the structural integrity when in use.
3Reliability
If the container needs to be leak-proof for liquid wastes, then containment reliability is improved, but the complexity of sealing and manufacturing increases
Solution Approach 1:
The container utilizes flexible corrugated material walls that inherently provide leak-resistant properties. The corrugated structure creates multiple barriers to liquid penetration, and when combined with sealed folding joints and integrated handles, forms a comprehensive leak-proof system that maintains containment reliability while remaining manufacturable.
Solution Approach 2:
The sealing function is merged into the container's folding and assembly structure rather than being a separate addition. The folding lines and joint formations themselves create the seals, eliminating the need for separate sealing components and simplifying manufacturing while maintaining leak-proof containment.

AI summary
A container comprises a knockdown carton made from a flat blank of corrugated material, and a knockdown lid. The carton comprises a center panel, foldable end panels, foldable side panels, and foldable corner panels. A pair of diametrically opposed corner panels are folded inwardly into contact with opposed end panels. The end panels comprise rectangular cutout holes surrounding foldable flaps. The lid has a central panel that is divided from integral end panels and integral side panels. A lid side panel extending vertically downwardly is coupled to the carton. Lid end panels have elliptical orifices that register with carton cutout regions and adjoining slots that align with handle anchor orifices. An alternative lid has flaps comprising major and minor segments separated by a diagonal fold line. The minor segment has an apex that releasably biases the flap in engagement with the end panel, yieldably locking the lid.
