Sparkling beverage container with improved bubbling behavior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage containers fail to optimize the duration and spatial distribution of bubbling in sparkling beverages, leading to a reduction in the perceived taste and aroma, as the geography of nucleation sites has been neglected despite studies on their chemistry and physics.
Innovation Solution
A sparkling beverage container with a barrier wall featuring a cruciform pattern of open pores on the bottom, occupying between 0.01% and 5% of the area, promotes convective mixing and sustained bubbling by creating central and parietal bubbles, with the cross shape and dimensions optimized for efficient gas exchange and prolonged effervescence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a smooth surface is used in the beverage container, then good transparency and aesthetic appearance are achieved, but bubbling performance and gas exchange are reduced
Solution Approach 1:
The invention applies local quality by creating pores only in the bottom portion of the container while keeping the rest of the surface smooth. This localized modification allows the bottom area to promote bubbling through gas exchange while the rest of the container maintains its smooth, transparent, and aesthetically pleasing surface.
2Productivity
If irregularities are created on the container surface to promote bubbling, then nucleation sites are formed, but transparency and aesthetic appearance deteriorate
Solution Approach 1:
The pores are confined to the bottom portion of the container, creating local quality that promotes bubbling only where needed. The rest of the container surface remains smooth and transparent, resolving the contradiction between bubbling performance and aesthetic appearance.
3Productivity
If the bottom surface area with pores is increased, then more nucleation sites are created and bubbling is enhanced, but the container structure and stability are compromised
Solution Approach 1:
The invention optimizes the pore parameters by limiting the porous area to 1-20% of the bottom portion and controlling pore dimensions (5-50 micrometers diameter, 10-100 micrometers depth). These parameter changes enable sufficient nucleation sites for enhanced bubbling while maintaining the structural integrity of the container.
4Productivity
If a complex nucleation pattern is created on the bottom, then bubbling distribution is improved, but manufacturing complexity increases
Solution Approach 1:
The bottom portion is segmented into a porous zone and a non-porous zone, with the porous zone further divided into multiple pores of controlled dimensions. This segmentation creates an optimized bubbling distribution while maintaining manufacturing feasibility through clear geometric definitions.
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 container achieves prolonged and efficient bubbling, with bubbles rising and mixing effectively, maintaining a curtain of bubbles for an extended period, enhancing the taste and aroma experience by optimizing the spatial distribution and duration of bubbling.
Implementation Method 1
The regions of bubble genesis in a glass are called nucleation sites. It has been found that the presence of irregularities in the surfaces of the container in contact with sparkling beverage favors the appearance of bubbles from the gas dissolved in said sparkling beverage.
Implementation Method 2
The interfaces between the liquid and the air pockets allow better gas exchange. The crevices then form nucleation regions.
Implementation Method 3
A convective mixing is obtained in the transverse plane and in the horizontal plane.
