Universal Connector Plug Slides to Seal Fluids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems lack a universal design for connectors, making it difficult to switch between different types of containers, and often include non-recyclable metal components that complicate safety and recycling procedures.
Innovation Solution
A closed loop dispensing system with a connector featuring a plug that slides between open and closed positions, locked by crown elements, allowing for universal compatibility and recyclable materials, preventing fluid leakage and exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are designed specifically for different container types, then reliability of fluid containment is improved, but adaptability to different container types deteriorates
Solution Approach 1:
The connector is designed with a standardized interface that can accommodate multiple container types including rigid bottles and flexible bags. The outer cap and plug assembly provides a universal connection mechanism that maintains reliable fluid containment across different container configurations, eliminating the need for multiple specialized connectors
2Reliability
If metal springs and valves are used in connectors, then reliability of dispensing function is improved, but ease of manufacture and recyclability deteriorates
Solution Approach 1:
The invention removes metal springs and valves from the connector design, extracting the problematic components that hinder recyclability and increase manufacturing complexity. The dispensing function is achieved through a simpler plug mechanism that can be made from recyclable materials
Solution Approach 2:
The design transitions from mechanical spring-loaded valves to a plug-based system with crown elements, changing the fundamental mechanism parameters. This allows the connector to be manufactured from single-material or easily separated recyclable materials while maintaining reliable dispensing control
3Reliability
If connectors require multiple components for dispensing control, then reliability of dosage control is improved, but device complexity increases
Solution Approach 1:
The invention combines multiple functions into the plug component itself. The plug integrates sealing, dosage control, and locking functions, eliminating the need for separate metal valves and springs. The crown elements provide locking capability while the plug geometry controls fluid flow, reducing overall component complexity

AI summary
A closed loop dispensing system comprises a connector connectable to a container for selectively dispensing the fluids from the container. The connector includes an outer cap having a first passage with an interior surface. The first passage can have variable cross-sectional areas over different regions of the first passage. The connector comprises a plug slidingly movable between an open position and a closed position, wherein, the plug allows passage of fluids present in the container in the open position, and the plug prevents passage of fluids out of the container in the closed position. The plug can have a variable cross-sectional area thereby preventing the plug from being disengaged with the outer cap or sliding out of the connector and into the container.
