Extraction Fitting Integration for Fluid Container Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transport and storage containers for liquids require complex assembly and maintenance, particularly with extraction fittings, and often rely on unnecessary components like sealing rings and union nuts, leading to increased production costs and environmental impact due to single-use designs.
Innovation Solution
A transport and storage container design featuring a plastic injection-molded extraction fitting that connects directly to the inner container's emptying nozzle, eliminating the need for a separate sealing ring and union nut, with a flexible inner shell and metal mesh outer casing for easy assembly and reconditioning, allowing for reusable and environmentally friendly disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate sealing ring and union nut are used to connect the extraction fitting to the inner container, then the connection is reliable, but the assembly and maintenance complexity increases
Solution Approach 1:
The sealing flange is integrated directly into the extraction fitting as a single injection-molded plastic component, merging the previously separate sealing ring and union nut into one unified element. This integration maintains the sealing function while eliminating the need for separate components, thereby reducing assembly complexity and the number of parts required.
2Reliability
If multiple separate components (sealing ring, union nut) are used for the extraction fitting connection, then the connection is secure, but the production cost increases
Solution Approach 1:
The sealing flange is manufactured as an integrated part of the extraction fitting through plastic injection molding, combining multiple previously separate components (sealing ring, union nut, fitting body) into a single molded part. This reduces the number of manufacturing steps, eliminates the need for separate procurement and assembly of multiple components, and lowers overall production costs while maintaining connection security.
3Reliability
If a complex assembly with multiple parts is used for the extraction fitting, then the connection is reliable, but the environmental impact increases due to more waste
Solution Approach 1:
The sealing flange is integrated into the extraction fitting as a single injection-molded component, reducing the total number of parts from multiple separate components to one unified element. This simplification reduces material consumption, minimizes packaging requirements, and decreases the volume of waste generated during disposal or incineration of the flexible inner shell, thereby reducing environmental impact.
4Reliability
If a separate sealing ring is used to seal the emptying nozzle, then the sealing is effective, but the number of components increases
Solution Approach 1:
The sealing flange with its sealing lip is integrated directly into the extraction fitting as a single molded component, merging the previously separate sealing ring into the fitting structure itself. This integration maintains effective sealing at the emptying nozzle while eliminating the need for a separate sealing ring component, thereby reducing the total number of parts.

AI summary
The container has a right parallelepiped or cubic shaped exchangeable inner container (2) with a connection port (12) for a withdrawal fitting (13). A sealing flange (29) is clamped between free front ends (31) of a threaded sleeve (19) and an inner collar (32) of an inlet port (21) of a housing of the withdrawal fitting for sealing an emptying port (26) of a flexible inner casing (14) in the housing, when screwing the inlet port onto the threaded sleeve welded at the connection port, where the emptying port is drawn through the connection port and the threaded sleeve.
