Storage holder for a dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage holders for foam dispensers are difficult to accurately assemble due to the challenge of positioning the foam pump relative to the coupling piece, leading to potential misalignment of the foam outlet and dispenser connection, which complicates the assembly process and affects the operational positioning of the storage holder.
Innovation Solution
A storage holder design featuring a liquid reservoir with a plug and a pump having an inlet tube with a clamping connection, where the spacer is positioned between the pump section and the plug to maintain a defined distance, allowing for easier alignment and assembly by simplifying the positioning of the foam or liquid outlet, and enabling easy disassembly by pulling the pump from the plug to separate the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the foam pump is screwed to the coupling piece, then the storage holder can be connected to the foam dispenser, but it is difficult to accurately position the foam pump relative to the coupling piece
Solution Approach 1:
The patent introduces a spacer as an intermediary component between the pump and the coupling piece. The spacer includes a pump receiving portion that receives the pump and a coupling piece receiving portion that receives the coupling piece. This intermediary structure simplifies the assembly process by providing predefined positioning features, eliminating the need for complex screwing operations while ensuring accurate positioning of the pump outlet relative to the coupling piece.
2Reliability
If the pump is firmly fixed to the plug, then the connection is stable, but disassembly requires excessive force that may damage components
Solution Approach 1:
The patent employs a dynamic clamping connection between the inlet tube and the plug. The clamping portion of the plug engages with the inlet tube to provide a secure connection during operation, ensuring reliability. However, the connection is designed to be reversible, allowing the pump to be easily removed from the plug by pulling without requiring excessive force that could damage components. This dynamic design balances connection stability with ease of disassembly for maintenance and recycling.

AI summary
The invention is directed to a storage holder 1 destined for placement in a liquid or foam dispenser, comprising a liquid reservoir 2, a pump 3 and a spacer 4. The liquid reservoir 2 has an opening 5 provided with a plug 6. The pump 3 is provided with an inlet tube 9, which inlet tube 9 is fixed into the opening of the plug by a clamping connection. The spacer 4 is provided with an opening for the inlet tube 9 and provided at its exterior with a means 11 to couple the storage holder 1 to the liquid or foam dispenser. The spacer 4 is positioned between the pump 3 and the plug and fixed into position relative to the plug 6 and relative to the pump 3 only by the clamping connection between inlet tube 9 and plug 6.
