Beer Pressure Cap with Integrated CO2 Cartridge and Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beer dispensing systems for containers like cans and barrels lack an efficient mechanism to both pressurize and dispense beer, often resulting in inadequate foam formation and potential gas bubble issues during dispensing.
Innovation Solution
A pressure tap attachment with a CO2 cartridge and valve arrangement, featuring a telescopic outlet pipe and lever-actuated valve system, which allows for controlled CO2 flow into the beer container, ensuring proper pressurization and dispensing while minimizing foam formation and gas bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate tap is used for dispensing beer, then dispensing function is provided, but device complexity increases and aesthetic integrity is compromised
Solution Approach 1:
The patent combines the pressurization function (CO2 cartridge) and dispensing function (tap mechanism) into a single integrated attachment. The tap is incorporated directly into the attachment body, eliminating the need for separate dispensing devices and reducing overall system complexity while maintaining both functions.
Solution Approach 2:
The attachment serves multiple functions: it pressurizes the beer container with CO2, controls the dispensing flow, and provides the actual dispensing outlet. This multi-functional design replaces what would traditionally require separate devices, simplifying the overall system while enhancing operational capability.
2Stress or pressure
If CO2 is introduced directly into the beer container, then pressurization is achieved, but gas bubbles and foam formation problems occur during dispensing
Solution Approach 1:
The CO2 cartridge is pre-positioned and connected to the beer container through sealed channels. The pressurization system is prepared in advance with proper sealing arrangements, ensuring that CO2 is introduced in a controlled manner that minimizes bubble formation. The valve mechanism is pre-configured to regulate gas flow and prevent excessive foaming during dispensing.
Solution Approach 2:
The patent introduces intermediate sealing elements and controlled flow channels between the CO2 source and the beer. These intermediary components regulate the gas-liquid interaction, preventing direct uncontrolled mixing that would cause excessive foam. The valve mechanism acts as an intermediary to control the timing and rate of CO2 introduction.
3Device complexity
If a compact attachment design is used, then aesthetic integrity is maintained, but ease of operation and access to controls is reduced
Solution Approach 1:
The attachment incorporates movable and adjustable components that allow operational access without compromising compact storage. The tap and control mechanisms can be extended or accessed through movable parts, enabling easy operation when needed while maintaining a compact profile when not in use. This dynamic design resolves the conflict between compactness and operability.
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 enables effective pressurization and dispensing of beer with enhanced foam formation, improved gas management, and a compact, user-friendly design that maintains the aesthetic and functional integrity of the beer container.
Implementation Method 1
Such tap attachments provide such a carbon dioxide pressure in the beer vessel that the beer is conveyed and foamed
Implementation Method 2
a valve arrangement, which, depending on whether it is arranged in an open or closed position, provides a fluid path for the beer
Implementation Method 3
Its end pointing into the hood opens into a valve which is fluidly connected to a riser channel which extends into the epee

AI summary
The pressure-pin support (101) comprises a rapier (102), which has a carbon dioxide channel (103'), which is in fluidic connection with a carbon dioxide cartridge over a valve arrangement. The carbon dioxide cartridge is bent and is arranged pointing with an upward neck. An operating unit is provided, which is a rotating mechanism, which is arranged in a recess.
