Closure Assembly Annular Channel Orifices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure assemblies for containers require complex seal arrangements and often have a single nozzle, which limits the efficiency and distribution of additive liquids when mixed with other liquids, such as in pharmaceuticals or beverages.
Innovation Solution
A closure assembly with a pressurized tank and a plug member featuring an annular channel with multiple orifices that seal and open simultaneously, allowing for a 'shower head' pattern of liquid distribution, improving mixing and distribution within the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single nozzle passage is used in the closure assembly, then the device structure is simpler, but the distribution and mixing efficiency of additive liquid is reduced
Solution Approach 1:
The single nozzle passage is segmented into multiple orifices (e.g., 3-5 small holes) arranged in a circular pattern within the plug member. This segmentation allows the additive liquid to be ejected through multiple streams simultaneously, improving distribution and mixing efficiency while maintaining a relatively simple overall nozzle structure in the plug member.
2Reliability
If multiple seals are arranged in the closure assembly to ensure sealing, then the sealing reliability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Multiple sealing functions are merged into a single annular seal element that engages with the boss member. The annular seal provides both axial and radial sealing in one component, eliminating the need for multiple separate seals and reducing overall device complexity while maintaining reliable sealing throughout the closure assembly.
Solution Approach 2:
The annular seal element serves multiple sealing purposes simultaneously - sealing between the plug member and boss member, sealing the interior volume of the tank, and sealing the exterior environment. This multi-functional seal reduces the total number of sealing components needed in the assembly.
3Productivity
If the plug member is designed with an annular channel and multiple orifices, then the liquid distribution pattern is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The multiple orifices are integrated directly into the plug member as a single molded or machined component, combining what would otherwise be multiple separate nozzle components. This integration reduces assembly complexity and aligns all orifices precisely during the single manufacturing process, reducing overall manufacturing precision requirements compared to assembling multiple precision nozzles.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables efficient and uniform mixing of additive liquids by using a 'shower head' pattern, enhancing the distribution and shelf life of two-component pharmaceuticals and other liquid mixtures, while simplifying the seal arrangement and reducing material complexity.
Implementation Method 1
a pressurised tank having an interior volume and a cylindrical wall with an open end
Implementation Method 2
the plug member has an annular channel arranged at a first side of the plug member adapted to sealingly engage with an annular boss member of the cylindrical wall of the pressurised tank

AI summary
A closure assembly (10) for a container comprising a pressurised tank (60) and a plug member (64), wherein the pressurised tank has an interior volume and a cylindrical wall (62) including an annular boss member (63) at its open end. The plug member has an annular channel (70) arranged at a first side (72) of the plug member adapted to sealingly engage with the annular boss member (63). The annular channel (70) has at least one orifice (80) extending from the channel floor (71 ) or outer side wall of the channel to a nozzle at the second opposite side (73) of the plug member. The orifice (80) is sealed from the interior volume of the tank (60) when the annular channel (70) is sealingly engaged with the annular boss member (63) in a first closed position, but is in fluid communication with the interior volume of the tank (60) when at least part of the annular channel (70) is no longer engaged with the annular boss member (63) in a second firing position, so that pressurised liquid is ejected from the nozzle.
