Rocker Closure Cover Pivoting for Secure Bottle Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closures, particularly for bottles, often require twisting or pulling to open and close, which can be cumbersome and may not provide a secure seal, especially for rocker-type closures that lack a reliable mechanism for easy access and sealing.
Innovation Solution
A rocker-type closure design featuring a shell with a cap portion and a cover that pivots using a mechanism involving pivot members and u-shaped guides, allowing the cover to transition between closed and open configurations while ensuring a secure seal and easy fluid flow, with an annular partition and recessed portions for efficient content dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional twisting or pulling closure mechanism is used, then the closure can be opened and closed, but the operation becomes cumbersome and may not provide a secure seal
Solution Approach 1:
The closure employs a dynamic rocker mechanism that transitions between closed and open positions through pivotal movement. The rocker cover pivots on a pivot member within the shell, allowing easy rockering motion while maintaining a secure seal when closed through the annular divider engagement with the annular partition.
Solution Approach 2:
The closure is divided into distinct functional segments: the shell with annular partition, the rocker cover with channel, and the annular divider. This segmentation allows each component to perform its specific function - the shell provides structural support, the rocker cover enables controlled access, and the annular divider ensures sealing - while working together to resolve the contradiction between ease of operation and seal security.
2Ease of operation
If a rocker-type closure is used for easy access, then opening becomes simple, but a reliable sealing mechanism becomes difficult to achieve
Solution Approach 1:
The annular divider acts as an intermediary sealing element between the rocker cover and the shell's annular partition. This intermediary component ensures that when the rocker cover is in the closed position, it forms a reliable seal against the annular partition, preventing leakage while still allowing the easy rockering motion for access.
3Ease of operation
If the cover is designed to pivot easily for open configuration, then access is improved, but the closed configuration may not provide a tight seal
Solution Approach 1:
The cover is designed with a pivot mechanism that enables dynamic movement between closed and open configurations. The pivot member allows the cover to rock easily for access, while the annular divider engagement with the annular partition ensures that when closed, a tight seal is maintained despite the dynamic nature of the connection.

AI summary
There is provided a closure having a shell and a cover. The shell includes a surface with a cap portion extending to secure around the neck of a bottle. An opening is provided to allow contents within the bottle to exit. A partition extends around the opening to define a passage for the contents. The cover has a top portion with a channel in communication with the passage and a channel mouth such that contents in the bottle exits when the cover is in an opened configuration. The cover has a divider positioned about the channel entrance and sized to seal against the partition when the cover is in a closed configuration. The cover is sized to fit within the shell when in the closed configuration and the cover pivots to an opened configuration exposing the channel mouth to allow contents to flow from the bottle.
