Integrated Coupling Piece with Support Legs for Pressure Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coupling systems for containers under pressure, used with both dispensing guns and handheld applicators, face challenges such as valve repositioning due to pressure changes, leading to inconsistent valve opening and potential spillage, and require separate shielding caps, increasing production complexity and supply chain burdens.
Innovation Solution
A dual-purpose coupling piece with an integrated cap and internal support legs, allowing for single-step production, which can be used with both dispensing guns and handheld applicators, featuring a pin-and-groove connection for quick and secure attachment, and a design that retains the valve stem position despite pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional valve system is used with separate shielding caps, then the valve can be protected during storage and transport, but the production complexity increases and the supply chain becomes more burdened
Solution Approach 1:
The patent combines the shielding cap function and the coupling piece function into a single integrated component. The coupling piece includes an integrated cap that shields the valve during storage and transport, and also serves as the coupling mechanism for attaching to dispensing guns or handheld applicators. This merging eliminates the need for separate shielding caps, reducing production steps and supply chain complexity while maintaining reliable valve protection.
2Productivity
If a Click-and-Fix coupling system is used, then the coupling can be quickly attached and detached, but the valve stem position may change due to pressure changes, leading to inconsistent valve opening
Solution Approach 1:
The patent incorporates a valve stem position retention feature that is pre-configured in the coupling piece design. The integrated cap and coupling structure include mechanical elements that maintain the valve stem in its correct position before coupling occurs. This preliminary positioning action ensures that when the Click-and-Fix coupling is quickly attached, the valve is already pre-positioned correctly, preventing inconsistent opening while maintaining the quick-coupling advantage.
3Adaptability or versatility
If separate coupling systems are designed for dispensing guns and handheld applicators, then each system can be optimized for its specific use, but the supply chain must manage multiple container designs
Solution Approach 1:
The patent designs a universal coupling piece that can interface with both dispensing guns and handheld applicators. The integrated cap and coupling structure are designed with standardized features that accommodate both types of applicators, allowing a single container design to serve multiple purposes. This universal design maintains the ability to optimize for specific uses while reducing the supply chain burden of managing multiple container variants.

AI summary
An improved coupling piece for the Click-and-Fix coupling of a disposable pressure container with a dispensing gun is provided, including an integrated cap and internal support legs for securing the position of the stem of the valve of the container when pressure increases inside the container, and which coupling piece may be produced as one single product using injection moulding. Further provided is an assembly of a container with the coupling piece, and a process for producing the coupling piece and the assembly. The coupling piece and/or the assembly may be further adapted for handheld use with a suitable handheld applicator.
