Twist Closure Assembly for Beverage Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drink bottle closure assemblies require a pulling motion to open or close the dispensing pathway, which can be inconvenient and may not provide a secure sealing mechanism.
Innovation Solution
A dispensing closure assembly that uses a rotating component to axially displace another component, allowing for simple twisting to open or close the dispensing pathway, ensuring a secure and easy-to-use sealing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pulling motion is used to open or close the dispensing pathway, then the closure assembly can separate components to allow liquid flow, but the operation becomes inconvenient and the sealing mechanism may not be secure
Solution Approach 1:
The patent inverts the conventional pulling motion into a twisting motion. Instead of pulling the closure assembly linearly to open or close it, the user twists the closure assembly rotational to engage or disengage the dispensing pathway. This inversion of motion type provides both ease of operation (twisting is more intuitive and requires less force) and reliable sealing (the twisting motion ensures proper engagement of sealing surfaces).
Solution Approach 2:
The closure assembly incorporates dynamic elements that respond to twisting motion. The closure portion and dispensing outlet are designed with movable components that dynamically transition between open and closed states based on the twisting input, ensuring reliable sealing when closed and proper flow when open.
2Ease of operation
If a pulling motion is used to open or close the dispensing pathway, then the closure assembly can control liquid flow, but the operation requires complex manual manipulation
Solution Approach 1:
The patent simplifies the user interaction by inverting the pulling motion into a twisting motion. The closure assembly is designed with a twisting mechanism that converts rotational input into the necessary component separation or engagement, reducing the complexity of manual manipulation while maintaining effective flow control.
Solution Approach 2:
The twisting mechanism serves multiple functions: it simultaneously controls the separation of components, engages or disengages the dispensing pathway, and maintains sealing integrity. This multi-functionality through a single twisting action reduces overall device complexity while improving ease of operation.

AI summary
In another aspect the invention is a (drink bottle or container) closure assembly as a unit havingan occlusion region providing first component, the first component being adapted for a closing engagement with a complementary bottle or container, and having a liquid passageway to be open from the bottle or container to an outlet below at least part of the occlusion region,as a second component, a spout or top with a dispensing outlet capable of being occluded by the occlusion region to provide a substantially liquid tight environment from an engaged liquid bearing bottle or container unless the second component rises from its dispensing outlet occluding condition, anda third component, rotation of which controls the rise and fall of the second component relative to said occlusion region.
