Sleeve-Like Fluid Container Fixing for Beverage Can Frothing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage containers with pressure containers face challenges in positioning and fixing the pressure container within the can, limiting the volume of liquid that can be excited to form froth, especially when the container is opened.
Innovation Solution
A fluid container with a sleeve-like design extending axially, featuring a central region with a constant cross-sectional area and a connecting region formed by compressing opposing regions of the container wall, allowing for a smaller diameter and thinner walls, which can be fixed within the beverage container using core bevels, eliminating the need for adhesives and enabling efficient fluid escape when opened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressure container is arranged in the beverage container, then the frothing effect is enhanced, but the positioning and fixing of the pressure container becomes problematic
Solution Approach 1:
The pressure container utilizes a thin-walled structure that can be deformed during insertion. The wall thickness is reduced to enable the container to be compressed into a compact state for insertion through the closure, then expand to its full shape inside the beverage container. This flexible shell approach solves both the fixing problem (by enabling secure insertion) and maintains the frothing function.
Solution Approach 2:
The pressure container transitions from a compressed, insertable state to an expanded, functional state inside the beverage container. The dynamic transformation allows the container to be easily inserted through the closure in a compressed state, then expand to its full diameter to properly position itself and function for frothing when the beverage is dispensed.
2Ease of operation
If the pressure container has a smaller diameter and thinner walls, then it can be fixed within the beverage container, but the volume for storing fluid is reduced
Solution Approach 1:
The pressure container employs parameter changes in wall thickness and diameter along its length. The central region has reduced wall thickness and smaller diameter to enable fixing within the beverage container, while the end regions have increased wall thickness and diameter to provide sufficient fluid storage volume. This gradual parameter change resolves the contradiction between compact fixation and adequate storage capacity.
Solution Approach 2:
Different regions of the pressure container have different wall thicknesses and diameters optimized for their specific functions. The central region has thin walls for flexibility and fixation, while the end regions have thicker walls for structural integrity and fluid storage. This local differentiation allows the container to simultaneously achieve compact fixation and adequate storage volume.
3Reliability
If the pressure container is arranged to excite larger volume of liquid, then the frothing effect is enhanced, but the pressure container requires retaining elements or adhesives for fixation
Solution Approach 1:
The invention extracts and eliminates the need for separate retaining elements or adhesives by integrating the fixation function directly into the pressure container structure. The thin-walled, deformable design allows the container to be inserted in a compressed state and expand to fix itself within the beverage container, removing the need for additional fixing components and simplifying the overall device.
Solution Approach 2:
The pressure container performs self-fixation through its deformable structure. By being inserted in a compressed state and then expanding to its full shape inside the beverage container, it automatically secures itself without requiring external retaining elements or adhesives. This self-service approach reduces device complexity while maintaining effective fixation for enhanced frothing.

Function Achieved in This Case
The fluid container is securely positioned within the beverage container, allowing a larger volume of liquid to be excited upon opening, enhancing the frothing effect while preventing displacement during pressure equalization and pasteurization.
Implementation Method 1
a part of the first end region is formed by the contacting of opposing regions of the fluid container wall
