Twist Closure With Segmented Orifice For Secure Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closures, particularly for bottles, face challenges in providing a secure seal and efficient dispensing mechanism that is easy to use and resistant to leakage.
Innovation Solution
A twist closure system comprising a shell with a raised and notched segment, a rotatable closure with a downwardly extending skirt and annual walls, and a stop flange, which aligns with the bottle's indented ridge and flanges to create a secure seal and allow fluid flow through notches when rotated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional closure is used to seal the bottle, then a secure seal is provided to prevent leaking, but the dispensing mechanism becomes complex and difficult to operate
Solution Approach 1:
The closure is segmented into distinct functional components: a closure body with sealing elements, a rotatable dispensing component with notched segments, and a bottle with corresponding raised segments. This segmentation allows the sealing function to be independent from the dispensing function, enabling simple operation while maintaining reliable sealing.
Solution Approach 2:
The closure incorporates a rotatable component that can dynamically transition between different positions (closed, dispensing, partially open). The notched segments rotate relative to the raised segments, allowing the system to switch between sealing mode and dispensing mode through simple rotational motion, greatly easing operation.
2Adaptability or versatility
If a complex twist closure mechanism is implemented to provide both sealing and dispensing functions, then functionality is improved, but the device complexity increases
Solution Approach 1:
The closure design integrates multiple functions into a unified structure where the same rotatable component serves both sealing and dispensing purposes. The notched segments work with raised segments to provide both the seal (when aligned) and the dispensing pathway (when rotated), eliminating the need for separate mechanisms and reducing overall complexity.
Solution Approach 2:
The sealing mechanism and dispensing mechanism are merged into a single integrated closure assembly. The notched segments and raised segments form a combined system where one component's rotation simultaneously controls both sealing and flow, simplifying the overall device structure while maintaining versatile functionality.
3Ease of operation
If the closure is designed to allow easy opening and dispensing, then ease of operation is improved, but the risk of leakage increases
Solution Approach 1:
The closure design incorporates pre-positioned notched segments and raised segments that are precisely configured before use. The notches are pre-aligned to match specific raised segments, ensuring that when the closure is rotated to the dispensing position, the alignment is already optimized for controlled flow without leakage, maintaining reliability while enabling easy operation.

AI summary
In one embodiment there is provided a twist closure combined with a bottle. The shell is secured between the twist closure that permits rotation of the closure with respect to the bottle while keeping the closure secured thereto. Rotation of the closure moves an orifice from a raised segment closing the bottle to an notched segment that permits the contents of the bottle to flow out of the orifice.
