Disposable Shaker Bottle Liner for Mixing and Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reusable shaker bottles are difficult to clean and prone to odor contamination, especially when used for powdered beverages, as existing solutions like mixing balls and grates require additional cleaning and may not ensure complete mixing.
Innovation Solution
A disposable, rigid liner for shaker bottles that fits within the container, eliminating the need for cleaning the bottle and cap, facilitating complete mixing of powdered drinks without additional mechanisms, and preventing odor buildup by containing the beverage within the liner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a reusable shaker bottle is used for powdered beverages, then the bottle can be used multiple times, but cleaning becomes difficult and odor contamination occurs
Solution Approach 1:
The invention divides the shaker bottle system into two segments: a reusable outer bottle and a disposable inner liner. The liner is removed after use and discarded, eliminating the need to clean the bottle itself. This segmentation allows the bottle to be reused indefinitely while the liner handles the sanitation burden.
Solution Approach 2:
The invention introduces a disposable plastic liner that is inexpensive and single-use. The liner is discarded after one use, replacing the need for cleaning the expensive reusable bottle. This follows the principle of using cheap, short-lived components to protect valuable, long-lived equipment.
2Manufacturing precision
If a mixing ball or grate is added to facilitate mixing, then mixing effectiveness improves, but device complexity and cleaning difficulty increase
Solution Approach 1:
The invention merges the mixing function directly into the liner wall by incorporating protrusions (ridges, ribs, or bumps) that extend into the bottle cavity. This eliminates the need for separate mixing balls or grates, as the liner itself performs both containment and mixing functions through its integrated structural features.
Solution Approach 2:
The liner serves multiple functions simultaneously: it contains the beverage, provides mixing surfaces through its protrusions, and acts as a disposable barrier. This multi-functionality eliminates the need for separate dedicated mixing components, reducing overall device complexity.
3Ease of operation
If liquid is left in the bottle after consumption, then convenience is improved, but odor buildup occurs due to bacteria
Solution Approach 1:
The invention extracts the sanitation-critical components (the inner liner that contacts the beverage) as a removable, disposable element. After use, the liner is taken out and discarded, preventing odor buildup in the reusable bottle. This extraction allows liquid to be left in the liner without contaminating the permanent bottle structure.

AI summary
A powdered drink shaker bottle is provided with a rigid, disposable liner to minimize clean up and eliminate residual odors. The liner is shaped to fit inside the cup of the bottle, and includes a plurality of projections to facilitate mixing of a powdered drink in the bottle. The projections eliminate the need for a separate, removable mixing device, such as a ball or grate. An optional cap liner may also be provided.
