Closure Lid Double Flap Securing Large Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for large-capacity containers, especially those made of deformable materials like corrugated cardboard, require multiple separate securing elements and complex adjustments, which can be weakened by container deformation under loading pressure, necessitating additional reinforcements for secure storage and transport.
Innovation Solution
A security system utilizing a closure lid with a double flap design that integrates with the container's edge, allowing a tension cord to be passed through a captive passage, forming a clamping connection with the container wall, and secured using conventional tension belts without additional aids, simplifying handling and securing the container even under deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate securing elements and complex adjustments are used, then the security of containers under loading pressure is improved, but the device complexity and handling difficulty increase
Solution Approach 1:
The patent combines the closure lid and securing element into a single integrated component. The closure lid includes integrated securing elements (such as straps or latches) that directly engage with the container opening, eliminating the need for separate securing devices. This merging reduces the number of components while maintaining reliable security under loading pressure.
Solution Approach 2:
The closure lid serves multiple functions simultaneously: it closes the container opening to secure the contents, and it incorporates integrated securing elements that perform the additional function of anchoring the container to the transport vehicle. This multi-functionality reduces the need for separate dedicated securing elements.
2Reliability
If separate securing elements are used, then the security against deformation is improved, but the ease of operation and handling deteriorates
Solution Approach 1:
By integrating the securing elements directly into the closure lid structure, the patent eliminates the need for separate securing components that would require individual adjustment and handling. The closure lid itself becomes the securing mechanism, simplifying the operation to a single action of closing and securing.
Solution Approach 2:
The closure lid with integrated securing elements performs the securing function automatically when closed, without requiring separate adjustment or assembly steps. The design enables the container to be secured through the natural closing action of the lid itself.
3Reliability
If additional securing reinforcements are added, then the reliability under dynamic loading is improved, but the quantity of securing elements and cost increase
Solution Approach 1:
The closure lid is designed to perform multiple securing functions simultaneously through its integrated elements, which can engage with various container opening configurations. This universal design provides adequate security reinforcement without requiring multiple separate securing devices.
Solution Approach 2:
The patent merges the closure and securing functions into a single integrated system, where the closure lid incorporates the necessary securing reinforcements. This eliminates the need for additional separate securing elements while maintaining reliability under dynamic loading conditions.

AI summary
A securing system that secures the storage of at least one filled large-capacity container (4) on a storage surface (7) comprises the large-capacity container (4), a securing element with a rim arranged on the upper side (44) of the container, the storage surface (7), and a clamping device (5) that connects the rim of the securing element to fixed points (71) on the storage surface (7). The securing element is formed by a closing lid (41) that closes the large-capacity container (4) and can be erected from a lid blank (1) made of material that can be folded against a restoring force. At least one double flap (2) projecting from a lid rim (410), which forms part of the lid blank (1), has a projection tab (21) extending from the lid rim (410) and a folded flap (22) hinged to and folded against the projection tab (21).The attachment tab (21) and the crimp tab (22) are detachably fixed to one another, forming a flat space (20) with a passage (201) through which at least one tensioned tensioning strand (50) of the clamping device (5) is captive. The tensioning strand (50) is guided such that the double tab (2) is pressed towards the bottom (42) of the container and against a container wall (431) of the large-capacity container (4) below the rim of the closure lid (410).
