Plastic Liquid Container Truncated Pyramid Funnel Bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inner containers for transporting and storing liquids, especially highly viscous materials, face challenges in complete drainage due to their design, which complicates the process and requires extensive rinsing and cleaning.
Innovation Solution
The inner container features a funnel-shaped bottom wall with four triangular funnel walls forming a truncated pyramid, ensuring a continuous reduction in flow profile towards the outlet neck, preventing liquid pockets and facilitating complete drainage with a recessed outlet armature for efficient liquid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the container shape is oriented toward maximizing container volume and adapting to the accommodating space defined by the transport pallet, then the container volume and space utilization are improved, but the drainage of residual liquid becomes incomplete and complicated
Solution Approach 1:
The bottom wall is given a special local quality by forming an outlet funnel with inclined funnel walls that converge toward the outlet neck. This localized geometric feature creates a flow profile that continuously reduces cross-section toward the outlet, preventing liquid pockets and enabling complete drainage of highly viscous materials, while the rest of the container maintains its volume-optimized shape.
2Volume of moving object
If the outlet neck is positioned to maximize container volume, then the container volume is improved, but liquid pockets form that prevent complete draining
Solution Approach 1:
The outlet funnel introduces a new dimensional aspect to the bottom wall geometry by creating inclined surfaces that converge in three-dimensional space toward the outlet neck. This dimensional transformation of the bottom wall into a funnel shape with varying cross-section ensures that liquid flows continuously toward the outlet without forming pockets, while the outlet neck remains positioned to maintain container volume.
3Reliability
If extensive rinsing and cleaning operations are performed to achieve complete drainage, then the completeness of drainage is improved, but the time and complexity of operations increase
Solution Approach 1:
The outlet funnel geometry enables the container to drain itself completely through its own structure. The inclined funnel walls and converging flow profile automatically guide all liquid, including highly viscous materials, toward the outlet neck without requiring external intervention such as rinsing or cleaning operations, thus achieving complete drainage with minimal time and effort.

Function Achieved in This Case
This design allows for complete drainage of residual liquids with minimal effort, reducing the need for complex rinsing and cleaning operations, while maintaining compatibility with standard transport pallets and outer jackets.
Implementation Method 1
the lateral funnel walls are inclined from a lower edge of a side wall towards the funnel bottom in each case, embodying a truncated pyramid above the funnel bottom together with the rear funnel wall and the front funnel wall

AI summary
An inner container for transporting and storing liquids includes an outlet neck and a bottom wall. The bottom wall connects two side walls, one rear wall and one front wall of the inner container to one another. The outlet neck is arranged in a funnel bottom of an outlet funnel embodied in the bottom wall, and includes one front funnel wall, two lateral funnel walls and one rear funnel wall, wherein the lateral funnel walls are inclined from a lower edge of a side wall towards the funnel bottom in each case, in such a way that the outlet funnel has the shape of a truncated pyramid above the funnel bottom.
