Self-Closing Beverage Lid for Spill Prevention and Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lids for liquid storage vessels either lack control over fluid exit, leading to potential spills when tipped or dropped, or have always-open apertures that do not provide insulation.
Innovation Solution
A beverage container closure with a selectively openable stopper assembly and air vent, featuring a telescoping design with cam followers and a biasing mechanism for fluid-tight sealing, allowing controlled fluid exit and resealing, and an optional dust cover for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid includes unobstructed apertures for liquid exit, then the ease of operation is improved, but the reliability is worsened due to potential spills when the vessel is tipped or dropped
Solution Approach 1:
The lid employs a dynamic stopper assembly that can move between open and closed positions. The stopper is biased by a spring mechanism to automatically close when not in use, preventing spills, while allowing easy opening by pushing the stopper against the bias to drink from the vessel.
Solution Approach 2:
The stopper assembly is designed to automatically return to the closed position after being opened, using a biasing mechanism that self-activates. This eliminates the need for the user to manually close the aperture, providing both spill prevention and ease of operation.
2Reliability
If the lid includes a means for selectively opening and closing apertures, then the reliability is improved for maintaining contents inside the vessel, but the device complexity is worsened
Solution Approach 1:
The lid is segmented into distinct functional components: a main body, a stopper assembly, a biasing mechanism, and a dust cover. This segmentation allows each component to perform its specific function independently while simplifying the overall structure and ease of manufacturing.
Solution Approach 2:
The stopper assembly is nested within the lid body, and the dust cover is nested over the stopper assembly. This nested configuration reduces the overall device complexity by integrating multiple functions within a compact structure while maintaining reliability for contents retention.
3Loss of substance
If the lid closes apertures to maintain contents inside the vessel, then the loss of substance is reduced, but the ease of operation is worsened due to additional mechanisms required
Solution Approach 1:
The biasing mechanism automatically closes the aperture by pushing the stopper into the closed position after the user finishes drinking. This self-closing feature reduces liquid retention loss without requiring the user to manually operate a complex closing mechanism, maintaining ease of operation.
4Object-affected harmful factors
If the lid includes a dust cover for protecting the opening, then the protection from environmental factors is improved, but the device complexity is worsened
Solution Approach 1:
The dust cover serves multiple functions: it protects the opening from dust and contaminants, and it can be rotated to cover or expose the button mechanism. This multi-functionality provides environmental protection without significantly increasing device complexity, as it integrates seamlessly with the existing lid structure.

AI summary
A beverage container closure or lid that is adapted for closing an open end of a beverage container. The lid is selectively couplable to the beverage container and includes a selectively openable stopper that when closed, creates a fluid-tight seal between the beverage container and the environment. The stopper may be selectively opened by a user by the user pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the user releases the button. Thus, a user may open and close the beverage container closure using a single hand without the need to remove the beverage container closure from the beverage container.
