Double-Walled Liquid Container Siphon Flow Passage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid storage containers with a double structure, the formation of a liquid ball between the flexible container and the siphon during liquid removal leads to increased residual liquid, as the flexible container is pushed towards the siphon, causing the liquid to become trapped and unable to be fully removed.
Innovation Solution
A concentric outer tube is arranged around the siphon with through holes in its wall, creating a liquid flow passage that allows the liquid to flow out from the through holes, down to an outlet opening, and then exit the container through the siphon, preventing the formation of a liquid ball and reducing residual liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas pressure is introduced into the outer container to push out the liquid, then the liquid removal efficiency is improved, but the flexible container moves toward and presses onto the siphon, causing liquid ball formation and increasing residual liquid
Solution Approach 1:
The siphon is divided into multiple sections: the original siphon tube and an additional outer tube with through holes. This segmentation creates multiple liquid discharge paths, allowing liquid to exit through the through holes before the flexible container fully contacts the siphon, thereby preventing liquid ball formation while maintaining efficient liquid removal
Solution Approach 2:
The outer tube with through holes acts as an intermediary structure between the flexible container and the original siphon. It provides an intermediate discharge path that allows liquid to escape before the flexible container directly contacts the siphon, preventing the harmful liquid ball effect while maintaining the beneficial pressure-driven liquid removal
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
This configuration ensures that even when the flexible container is closely attached to the siphon due to reduced liquid levels, the liquid has a clear outflow route, effectively preventing the formation of a liquid ball and minimizing residual liquid in the container.
Implementation Method 1
gas pressure (arrow P in the figure) is introduced into the outer container 3, and the liner 2 is pressed from the outside, so that the liquid accommodated in the liner 2 flows out to an exterior of the container
Implementation Method 2
a plug provided with a siphon serving as a liquid flow passage and a gas flow passage is attached

AI summary
A liquid storage container has a double structure provided with an outer container forming an outer shell and a liner arranged in the outer container, the liner accommodating a liquid, wherein the liquid is pushed out from the liner by gas pressure introduced into the outer container so as to flow out to an exterior of the container from a siphon of a plug attached to a stopper portion of the outer container, a substantially concentric drop tube is arranged on an outer periphery of the siphon so as to form a space portion serving as a liquid flow passage, a through hole is formed on a tube wall of the drop tube, and an outlet opening for making the inflow liquid coming from the through hole flow out from the liquid flow passage.
