Paper Beer Container Structure for Foldable Pressurized Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beverage containers for carbonated beverages, such as kegs, metal cans, and glass bottles, face challenges like non-foldability, high energy consumption, and inability to withstand gas pressure, making them inefficient for storage and use with carbonated beverages.
Innovation Solution
A self-supporting paper-based beverage container with an inner liquid sealant layer, a deformable inner bag, and a beverage delivering tube connected to a gas pressure inlet, allowing the container to be folded and maintaining gas and liquid tightness, enabling efficient storage and dispensing of carbonated beverages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a paper-based container is used for carbonated beverages, then the container can be folded by hand and stored space-efficiently, but it cannot withstand the gas pressure of the carbonated beverage
Solution Approach 1:
The patent applies composite materials by combining paper-based material with plastic layers (inner sealant layer and outer protective layer) to create a multi-layer structure. This composite construction allows the container to maintain the foldability and lightness of paper while gaining the pressure resistance and liquid barrier properties of plastic, thereby resolving the contradiction between storability and pressure withstand capability
Solution Approach 2:
The patent segments the container structure into multiple functional layers: paper-based material for structural framework and foldability, inner sealant layer for liquid and gas barrier, and outer protective layer for additional strength. This segmentation allows each layer to specialize in one function, enabling the overall structure to achieve both foldability and pressure resistance simultaneously
2Productivity
If gas pressure is increased to deliver beverage through the tube, then beverage can be delivered effectively, but the container may burst or leak if pressure is not controlled
Solution Approach 1:
The patent implements feedback control through the deformable diaphragm that responds to pressure changes. As gas pressure builds to push beverage through the tube, the diaphragm deforms to accommodate volume changes and provides visual feedback on pressure levels. This allows effective beverage delivery while preventing excessive pressure that could cause bursting, as the system self-regulates based on the diaphragm's mechanical response
3Volume of moving object
If the container is made completely flexible for folding, then it can be compressed for storage, but it cannot maintain structural stability when filled with carbonated beverage
Solution Approach 1:
The patent segments the container into a rigid structural framework (paper-based material) and flexible functional components (sealant layers and diaphragm). The paper framework maintains structural stability and shape when filled, while the flexible sealant layers and diaphragm allow the container to be folded and compressed for storage when empty, thus resolving the contradiction between storability and structural stability
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 paper-based container effectively withstands gas pressure, can be easily folded for space-saving storage, and maintains beverage freshness by using external gas pressure to increase carbonation levels, addressing the limitations of existing containers.
Implementation Method 1
at least one inner liquid sealant layer welded to the paper based material
Implementation Method 2
beverage can be delivered through the beverage delivering tube due to gas pressure fed into the beverage container
Implementation Method 3
an inner bag for holding a beverage and which inner bag has at least a deformable wall part which is compressible
