Adaptor for Slider Valve Fitment Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slider valve fitments and collars are limited to use with specific spout and valve assembly designs, preventing compatibility with containers having different designs.
Innovation Solution
An adaptor with a threaded outer ring collar, interior ring collar, and O-ring grooves that allows the slider valve fitment to be used with various spout and valve assemblies, forming seals to prevent fluid leakage and enable fluid flow through an inverted dome structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a slider valve fitment and collar are designed for a specific spout and valve assembly design, then the sealing and dispensing function is reliable for that specific design, but the adaptability to different spout and valve assembly designs is limited
Solution Approach 1:
The adaptor acts as an intermediary component between the slider valve fitment and various spout/valve assembly designs. It includes a collar portion that interfaces with the spout and valve assembly, and a fitment portion that interfaces with the slider valve, enabling compatibility across different designs while maintaining reliable sealing through O-rings and gaskets positioned at each interface
Solution Approach 2:
The adaptor is designed with universal compatibility features, including a collar portion with internal threads and engagement structures that can accommodate multiple spout and valve assembly designs, and a fitment portion with standardized threading and sealing surfaces that interface consistently with the slider valve mechanism, allowing one adaptor design to serve multiple container types
2Adaptability or versatility
If an adaptor is introduced to enable compatibility with different spout and valve assemblies, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The adaptor is segmented into distinct functional portions: a collar portion for interfacing with the spout and valve assembly, a fitment portion for interfacing with the slider valve, and integrated sealing elements (O-rings and gaskets). This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity through modular construction
Solution Approach 2:
The adaptor merges multiple functions into a single integrated component: it combines the collar structure for spout engagement, the fitment structure for valve connection, and the sealing elements (O-rings and gaskets) into one unified part that can be molded as a single piece, reducing the total number of components needed in the system

AI summary
This invention relates to an adaptor used in a fitment valve assembly, said adaptor comprising an outer ring collar having a top and a bottom, and an outer and an inner surface; a flange molded to the bottom of said outer ring collar; an interior ring collar having a top and a bottom, and an outer and an inner surface molded in adjacent relationship to said outer ring collar near the top of said interior ring collar; an inverted dome structure molded toward the bottom of said inner surface of said interior ring collar defining at least one opening for the flow of fluid there-through; a groove for an O-ring molded in said inner surface of said interior ring collar above said dome structure; a lip molded onto said bottom of said interior ring collar for forming a seal with said fitment valve assembly; and a groove for an O-ring molded in said outer surface at the bottom of said interior ring collar.
