Beverage container cover assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage containers often experience spillage and splashing due to inadequate sealing and design of lids, which fail to effectively transition between open and closed positions, leading to leakage and inconvenience during transport and consumption.
Innovation Solution
A lid assembly for beverage containers featuring a rotatable lid cover with a biasing element, such as magnets, and a gasket that seals the vent when closed, along with projections and recesses to minimize splashing, allowing for smooth transition between open and closed positions, reducing spillage and splashing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional lid design is used, then the structure is simple, but spillage and splashing occur due to inadequate sealing and poor transition between open and closed positions
Solution Approach 1:
The lid is divided into separate functional components: a lid body with vent and a rotatable lid cover with sealing flange, allowing each part to perform its specific function optimally while maintaining overall simplicity
Solution Approach 2:
The lid cover is designed to rotate between open and closed positions dynamically, transitioning smoothly to seal or expose the vent as needed, preventing spillage during motion while maintaining structural simplicity
2Ease of operation
If the lid cover rotates freely without constraints, then ease of operation is improved, but splashing occurs due to uncontrolled movement
Solution Approach 1:
The sealing flange with gasket is positioned to engage with the lid body vent perimeter before the lid cover completes its rotation to closed position, preventing liquid from splashing out during the transition by creating a seal in advance
Solution Approach 2:
The gasket acts as an intermediary sealing element between the lid cover and lid body, facilitating smooth rotation while preventing liquid escape through the vent perimeter
3Reliability
If the lid cover fully occludes the vent when closed, then sealing is improved, but fluid communication is lost when opening is needed
Solution Approach 1:
The lid cover rotates to dynamically transition between fully occluding the vent for sealing and fully exposing it for fluid communication, allowing easy access to beverages while maintaining seal integrity when closed
4Reliability
If a gasket is added to seal the vent, then sealing effectiveness is improved, but device complexity increases
Solution Approach 1:
The gasket is integrated with the lid cover as a unified component, combining the sealing function with the lid cover structure itself, thereby improving vent sealing without significantly increasing overall device 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
The solution effectively reduces spillage and splashing by ensuring a secure seal when the lid is closed and allowing fluid communication when open, enhancing the usability and safety of beverage containers during transport and consumption.
Implementation Method 1
a biasing element coupled to at least one of the lid and the lid cover, the biasing element biasing the lid cover from transitioning from the closed position to the open position
Implementation Method 2
The gasket engages with the other of the lid or the lid cover when the lid cover is positioned in the closed position with respect to the lid, and the gasket blocks fluid communication between the vent and the storage compartment when the lid cover is in the closed position

AI summary
A lid assembly is provided that is configured to enclose a beverage within a beverage container. The lid assembly includes a lid (130), a lid cover (180), and one or more magnetically-interfacing elements (156,158,190) that bias the lid and lid cover with respect to each other. To reduce spillage, various embodiments reduce contact between surface(s) of the lid and lid cover, and/or include a gasket (260) the selectively seals a vent (154).
