Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for foodstuffs or dried beverages face issues with stability, impermeability, and production complexity, particularly at the bottom part, leading to instability and potential leakage during filling and processing.
Innovation Solution
A container design featuring a flat bottom section with an abutment flange and a radially inward protruding support ring, ensuring a secure connection between the bottom part and the container wall, which maintains impermeability under compression and uneven surfaces, and allows for efficient force transmission and adaptation to different applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bottom part is connected to the container wall with a multi-layered arrangement, then the connection strength is improved, but the production complexity increases and container volume decreases
Solution Approach 1:
The bottom connection structure is segmented into distinct functional components: a bottom part with an upwardly protruding border flange, and a container wall with a support ring. This segmentation allows each component to be manufactured separately and then assembled, simplifying production while maintaining connection strength through the distributed contact area between the flange and support ring.
Solution Approach 2:
The connection is enhanced by utilizing the vertical dimension through the upwardly protruding border flange that extends into the container interior space. This vertical protrusion creates an overlapping contact area with the support ring, transforming a potentially simple radial connection into a three-dimensional interlocking structure that improves strength without requiring multiple layers in the radial direction.
2Stability of the object's composition
If the standing surface area is increased, then the container stability is improved, but the container volume decreases for the same height
Solution Approach 1:
The solution moves the stability-enhancing structure into the vertical dimension rather than increasing the horizontal footprint. The upwardly protruding border flange extends vertically into the container interior, creating a larger effective contact area with the support ring without increasing the container's base diameter. This allows the container to maintain its external volume while achieving improved stability through the internal vertical structure.
3Ease of manufacture
If the connection between bottom part and container wall is simplified, then the production is easier, but the impermeability under compression is compromised
Solution Approach 1:
The connection structure is segmented into the border flange and support ring, which can be manufactured using standard forming processes and then assembled through a simple insertion operation. This segmentation maintains manufacturing ease while the resulting distributed contact area between the flange and support ring ensures impermeability by providing multiple contact points that prevent fluid leakage under compression loads.
4Adaptability or versatility
If insertion limitations are added to hold stacked containers, then the stackability is improved, but the structural complexity increases
Solution Approach 1:
The upwardly protruding border flange serves multiple functions simultaneously: it provides structural support for the bottom connection, creates impermeability through contact with the support ring, and acts as an insertion limitation for stacked containers. By making this single structural element multi-functional, the patent improves stackability without adding separate dedicated components, thereby avoiding increased structural complexity.

AI summary
A container for receiving foodstuff or dried beverages comprising a surrounding container wall, an upper container opening and a bottom part opposite to the container opening and connected to a lower end section of the container wall, wherein the bottom part includes an essentially flat bottom section and an abutment flange which protrudes at least in some locations from the bottom section in the direction of the container opening, and the lower end section of the container wall includes a support ring protruding radially inwards from the end section. The bottom part and the lower end section is connected between the abutment flange, an inner side of the container wall, and between the lower side of the bottom section and an upper side of the support ring.
