Pallet Container Lid Fastening Trough Liquid Ingress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers are not adequately protected against liquid ingress, as existing fastening mechanisms allow liquids to penetrate through recesses and openings, compromising the interior's protection.
Innovation Solution
The container features a trough-shaped recess on the side walls that can be folded over the base and under the lid, with a U-shaped section on the cover that engages with a catch or hook fastening means, preventing liquid penetration by forming a strong counter-holder and ensuring the side walls are closed when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If openings are formed on the side walls for fastening the lid, then the lid can be locked to the side walls, but liquid can penetrate through the openings into the container interior
Solution Approach 1:
The patent introduces a flange as an intermediary element that extends horizontally from the side wall at the opening location. This flange acts as a mediator between the opening and the container interior, creating a protective barrier that prevents liquid from directly entering through the opening while still allowing the fastening mechanism to function.
Solution Approach 2:
The patent adds a horizontal dimension to the side wall structure by extending the flange perpendicular to the main wall surface. This dimensional extension creates an overhang that blocks liquid path from the opening to the interior, effectively using spatial geometry to prevent liquid ingress while maintaining fastening functionality.
2Productivity
If the side walls are made collapsible for compact packaging, then transportation efficiency improves, but the structural strength during use may be reduced
Solution Approach 1:
The side walls are divided into multiple segments connected by fold lines, allowing the structure to be segmented for compact folding during transportation while maintaining structural integrity when erected. The segmentation enables the walls to collapse flat for efficient stacking without compromising the strength of individual wall sections during use.

AI summary
The invention relates to a container, in particular a pallet container, comprising a base, side walls (3a), and a lid (4) that can be placed on the side walls (3a). The lid (4) is provided with a means (5) for fastening the lid (4) to at least one of the side walls (3a), and a recess (6) is formed in the at least one side wall (3a) with which the fastening means (5) interacts. According to the invention, the recess is formed by a trough (6), which can be located on an inner side (7) and/or an outer side (8) of the container. Advantageously, the side wall (3a) is closed in the area of the trough (6), and the fastening means (5) is provided to engage in the recess (6) to fasten the lid (4) to the side wall (3a).
