Container Closure Rotary Stop for Hands-Free Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closures require constant pressure to maintain the pouring opening in an open position, making them inconvenient for prolonged serving, especially in scenarios like restaurants or aviation catering, and are complex to manufacture due to additional required components for blocking the closure lever.
Innovation Solution
A container closure with a rotary element that forms a stop with the closure lever to block it in the open position, allowing easy operation and simple manufacturing with fewer components, featuring a spring-loaded locking lever that can be easily held open with the thumb and automatically closes when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components are added to block the closure lever in the open position, then the closure lever can be blocked, but the device becomes more complex to manufacture
Solution Approach 1:
The rotatable element serves multiple functions: it blocks the locking lever in the open position, provides a user interface for operation, and integrates with the existing closure structure. This multi-functionality eliminates the need for separate dedicated blocking components, thereby reducing manufacturing complexity while maintaining reliability.
Solution Approach 2:
The blocking function is merged into the rotatable element that is already part of the closure assembly. Instead of adding a separate blocking mechanism, the existing rotatable element is given the additional function of blocking the locking lever, thus avoiding increased manufacturing complexity.
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 convenient and intuitive pouring without constant pressure on the lever, while being simpler and more cost-effective to produce, as it uses fewer components and a straightforward mechanism to maintain the open position.
Implementation Method 1
a compression spring (34) arranged in the lower part (32) and acting on the locking lever (33) in the actuation direction
Implementation Method 2
a rotatable element (313) arranged on the outer side of the lower part (32) and forming a tab (313) extending in the actuation direction, wherein the tab (313) forms a stop with the locking lever (33) in a blocking 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.
