Beverage Lid Tab With Concave Area For Vent Score Break
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage container lids with separate vent openings require reconstruction of the basic design to facilitate efficient vent opening, and there is a need for a tab that can effectively create both the main and vent openings without altering the conventional design.
Innovation Solution
A beverage container lid with a tab that includes a concave area at the handle end, allowing force to be transferred to a raised, convex-shaped vent panel to break the vent score, ensuring the vent opening is created efficiently without reconstructing the container end, and the tab design allows for controlled force application by varying the alignment and shape of the vent panel and concave area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional tab design is used to create the main opening, then the basic container end design is maintained, but the tab cannot efficiently create the vent opening without reconstructing the container end
Solution Approach 1:
The tab is designed to perform multiple functions: it can create the main opening by breaking the mouth score and can also create the vent opening by breaking the vent score. This multi-functionality allows a single conventional-looking tab to serve both purposes without requiring separate mechanisms or reconstructing the container end design.
Solution Approach 2:
The tab is made rotatable about the rivet, allowing it to dynamically change orientation. By rotating the tab to different angular positions, the user can align the tab's force application point with either the mouth score or the vent score, enabling the tab to adaptively create either opening as needed.
2Ease of operation
If the vent panel is raised or protrudes from the main panel, then force can be effectively applied to break the vent score, but the container end design becomes more complex
Solution Approach 1:
The vent panel is raised or protrudes from the main panel surface, creating a localized structural variation. This raised portion concentrates the applied force from the tab onto a smaller area of the vent score, making it easier to break the vent score and create the vent opening without requiring complex mechanisms throughout the entire container end.
3Ease of operation
If the tab is rotated to cover the vent panel, then controlled force application is achieved, but the operation becomes more complex
Solution Approach 1:
The tab is pre-positioned and riveted to the container end in a conventional location. The user simply needs to rotate the tab to the appropriate angle and apply downward force. This preliminary positioning of the tab eliminates the need for separate vent opening mechanisms or complex操作步骤, allowing quick access to both opening functions through simple rotation and pressing actions.

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 enables efficient creation of a vent opening without altering the conventional container end design, preventing liquid from filling the vent hole and providing a safe, force-multiplying mechanism for opening the vent, allowing for controlled breakage of the vent score.
Implementation Method 1
A force may be more conveniently applied thereto to sever the second severable tab portion and form a vent opening in the container end
Implementation Method 2
break the vent score surrounding a vent panel

AI summary
A container lid includes a conventional main or pour opening and a vent opening spaced from the main opening. A vent score defines the shape of the vent opening, and a vent panel covers the vent opening. The vent panel has a raised convex shape. The lower surface of the tab handle includes a protruding portion, seen as a concave shaped element when viewed from above the container lid. The protruding portion of the tab handle can be aligned with the vent panel so application of a downward force on the tab handle transfers force to the vent panel and breaks the vent score. The shapes of the vent panel and concave element of the tab handle can be adjusted for selective and controlled force transfer to create the vent opening.
