Shaker Bottle Lid With Nesting Loop and Stable Flip-Cap Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaker bottle designs suffer from unstable pivoting connections, material inefficiency, elevated lid structures obstructing the user's nose, and restricted pivot ranges of the flip cap and carry loop, leading to awkward drinking angles and increased manufacturing costs.
Innovation Solution
A container lid with a flip cap and nesting carry loop design featuring integrally formed slots and recesses, allowing for stable, independent pivoting with a 180-degree range, accommodating the user's nose, and optimizing interior volume for improved mixing dynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cylindrical connections are used for flip cap and carry loop, then the structure is simple to manufacture, but the pivoting becomes unstable and sticky due to shrink and warp
Solution Approach 1:
The patent changes the geometric parameters of the connection structure from conventional cylinders to flattened oval-shaped slots with rounded portions. This parameter change eliminates the shrink and warp issues of cylindrical connections while maintaining manufacturing simplicity through injection molding processes.
Solution Approach 2:
Instead of using protruding cylindrical connectors that are prone to deformation, the patent inverts the approach by using recessed flattened slots that receive and stabilize the rounded portions of pivotable elements. This inversion provides inherent stability against shrink and warp.
2Ease of operation
If cylindrical connections are used for flip cap and carry loop, then the connection structure is robust, but the lid elevation increases creating an obstacle to the user's nose
Solution Approach 1:
The patent extracts the unnecessary height from conventional cylindrical connections by using flattened oval-shaped slots that lie closer to the lid surface. This extraction reduces lid elevation while maintaining the robust connection function, thereby eliminating the obstacle to the user's nose.
3Adaptability or versatility
If conventional cylindrical connections are used, then the structure is straightforward, but the pivot range is restricted and the elements interfere with each other's motion
Solution Approach 1:
The patent implements a nesting arrangement where the carry loop connector nests inside the cap body, and both elements pivot independently within flattened oval-shaped slots. This nesting configuration increases pivot range while preventing interference between elements, achieving adaptability without excessive complexity.
4Productivity
If dome-shaped or elevated lids are used to provide airspace for mixing, then mixing functionality is enhanced, but the lid structure becomes more complex and uses more material
Solution Approach 1:
The patent segments the lid structure by integrating flattened oval-shaped slots directly into the lid body rather than using separate cylindrical connection components. This segmentation maintains the necessary airspace for mixing while simplifying the overall structure and reducing material usage.

AI summary
A container lid, preferably for shaker bottles, with independently pivotable flip cap and carry loop that is configured to nest inside the flip cap. The lid body has integrally formed slots shaped and configured to retain narrow rounded portions of the interconnectable flip cap and carry loop. The underside of the lid may have one or more recesses that increase interior container volume, thus enhancing mixing functionality. The new structure provides space to accommodate a drinking user's nose and allows for 180-degree range of pivot for the flip cap and carry loop.
