Bottom-Injection Beverage Container to Reduce Foam and Air Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage containers, especially those used for draft beer, suffer from excessive foam formation and flavor degradation due to air contact when beer is poured from the top, and existing solutions like magnetic sealing are prone to rust and high production costs.
Innovation Solution
A beverage container with an injection hole at the bottom that uses a holder and locking member with elastic arms to automatically open and close the hole for efficient foam control and air minimization, featuring a packing member to prevent leakage and a simplified structure for cost-effective manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If draft beer is poured into the beverage container through the upper opening, then the beverage container can be filled with beer, but excessive foam is generated on top of draft beer and flows down causing user discomfort and degrading flavor quality
Solution Approach 1:
The patent inverts the conventional pouring method by injecting beer through the bottom of the container rather than pouring from the top. The injection hole is positioned at the bottom of the container body, and beer is injected upward through this hole, which prevents foam generation and allows smooth filling without excessive foaming.
Solution Approach 2:
The patent introduces a holder as an intermediary component that mediates between the injection hole and the beer stream. The holder includes a receiving space that guides the beer injection and controls the filling process, preventing direct contact between the beer stream and air that would cause foam formation.
2Object-generated harmful factors
If a hole is formed on the bottom of the beverage container for injection, then foam can be controlled, but the hole must be sealed after injection which makes the device difficult to adapt
Solution Approach 1:
The holder is designed to automatically return to its initial position after beer injection using its own elastic properties. The holder includes an elastic arm that bends during injection and then automatically rebounds to close the injection hole, eliminating the need for separate sealing mechanisms or additional components.
Solution Approach 2:
The patent changes the physical state of the holder from rigid to flexible by incorporating an elastic arm. This allows the holder to dynamically change its position and shape during the injection process, opening to allow beer flow and then automatically closing to seal the hole without additional mechanisms.
3Productivity
If beer is poured into the beer cup from the top, then the container can be filled, but beer is easily oxidized by coming into contact with air affecting taste and quality
Solution Approach 1:
The patent inverts the filling direction by injecting beer from the bottom upward through the container body. This approach minimizes the beer's exposure to air during filling, as the beer rises through the container rather than falling from above, significantly reducing oxidation and preserving taste and quality.
Applied Scientific Principles
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 effectively controls foam formation, maintains the natural taste of beverages by minimizing air contact, and prevents leakage, making it convenient and cost-effective for long-term use without the need for additional sealing mechanisms.
Implementation Method 1
a locking member engaged with a lifting wall of the holder, having a plurality of elastic arms that come into contact with a lower surface of the bottom of the container body and resiliently biases the holder downwards
