Shaker Cup Cap with Pivot Handle and Segmented Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caps for shaker cups and similar vessels often fail to provide a secure, leak-proof seal during transport and mixing, and lack easy cleaning and user-friendly handling features, leading to potential spills and unsanitary conditions.
Innovation Solution
A cap design featuring a securely attachable handle that moves independently of the closure mechanism, a sealable opening for drinking, and detachable components for thorough cleaning, with a pivot hinge mount allowing the handle to rotate freely and a removable sealing member for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the handle is securely connected to the cap to prevent separation during transport, then the reliability of the connection is improved, but the handle may swing down and hit the user in the face when the user tilts the vessel to drink
Solution Approach 1:
The handle is designed to rotate about a pivot hinge mount, transforming it from a static rigid connection to a dynamic movable connection. This allows the handle to adapt its position based on the vessel's orientation, preventing it from hitting the user's face during drinking while maintaining secure attachment to the cap through the pivot hinge mechanism
2Device complexity
If the closure mechanism is integrated with the handle, then the device complexity is reduced, but inadvertent downward pressure on the handle could cause the spout closure mechanism to open and spill contents
Solution Approach 1:
The closure mechanism is separated from the handle into independent functional components. The closure mechanism is integrated with the cap rather than the handle, creating functional independence. This segmentation ensures that handle movement does not inadvertently trigger closure mechanism opening, preventing spills while maintaining reasonable structural complexity
3Ease of operation
If the cap includes a sealable opening for drinking, then the ease of operation is improved, but the cap may leak during transport and mixing if the seal is not secure
Solution Approach 1:
The closure mechanism is designed to seal the opening before the user begins drinking. The user must actively open the closure mechanism to access the opening, ensuring the seal is securely closed during transport and mixing. This preliminary sealing action prevents leaks while allowing convenient drinking when the closure is intentionally opened
4Device complexity
If the cap components are integrated as a single piece, then the device complexity is reduced, but thorough cleaning becomes difficult
Solution Approach 1:
The cap is divided into multiple separable components including the cap body, closure mechanism, and handle. These components can be detached from one another, allowing each component to be thoroughly cleaned independently. This segmentation enables complete disassembly for cleaning while maintaining reasonable structural complexity when assembled

AI summary
A cap for a drinking vessel, and particularly a shaker cup. The claimed cap can be securely attached to the drinking vessel or shaker cup to avoid leaks, and also includes a sealable opening through which the contents of the drinking vessel can be poured or drunk and a handle that is convenient for a user and which is attached to the cap in such a manner that the handle moves somewhat freely relative to the cap and the mechanism for closing the opening in the cap. Any non-integral components that come into contact with the contents of the vessel are easily detachable to facilitate thorough cleaning.
