Container Closure Lever Lock for Hands-Free Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closures require continuous pressure to maintain the opening position of the closure lever, making them inconvenient for prolonged pouring, especially in scenarios like hospitality or airline services where multiple servings are needed quickly.
Innovation Solution
A container closure with a rotating element that forms a stop with the closure lever to block it in the opening position, allowing the lever to be easily retained in the open position without continuous pressure, and automatically returns to the closed position when the rotating element is released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional components are added to provide blocking function for the closure lever, then the lever can be blocked in the opening position, but the manufacturing complexity increases
Solution Approach 1:
The rotating element serves multiple functions: it can be rotated to a blocking position to form a stop with the closure lever, and it can also be rotated to a releasing position to permit pivoting of the closure lever. This multi-functionality eliminates the need for separate blocking components.
Solution Approach 2:
The blocking and releasing functions are achieved by changing the rotational position parameter of the rotating element. By rotating to different angular positions, the same component provides different functions, avoiding the need for multiple discrete parts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and intuitive operation with minimal components, reducing manufacturing complexity and allowing easy pouring without continuous pressure, while ensuring the closure lever remains in the open position until intentionally closed.
Implementation Method 1
a compression spring which acts in a closing direction on the closure lever in order to automatically return the closure lever into the closing position

AI summary
The invention discloses a container closure (3) for closing a vessel (2). The container closure (3) has a pouring opening (37) for pouring a liquid out of the vessel (2), a closure body (36) by means of which the pouring opening (37) can be closed, and also a closure lever (33) which interacts with the closure body (36). By being pressed by a finger of the user, the closure lever (33) can be pivoted from a closure position, in which the closure body (36) closes the pouring opening (37), to an opening position, in which the closure body (36) unblocks the pouring opening (37). The container closure (3) also has a rotary element (31) which can be rotated about a vertical axis relative to the closure lever (33) in order to form a stop with the closure lever (33) in a blocking position and thereby to block the closure lever (33) in its opening position and to allow the closure lever (33) to pivot between the closure position and the opening position in a release position.
