Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foam dispensing containers face challenges in achieving stable foam quality due to inadequate air-liquid mixing, varying assembly gaps, and increased pressure requirements, leading to inconsistent foam production.
Innovation Solution
The implementation of multiple liquid intake paths and air intake paths that converge at air-liquid confluence portions, connected to an air-liquid mixing chamber through specific flow path configurations, ensures efficient mixing and stable foam discharge without excessive liquid flow upon a single press.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single liquid inlet is used to deliver foaming liquid into the air-liquid mixing chamber, then the device complexity is reduced, but the air-liquid mixing efficiency is insufficient and foam quality is unstable
Solution Approach 1:
The single liquid inlet is divided into multiple liquid inlets (first liquid inlet and second liquid inlet) positioned at different locations. This segmentation allows foaming liquid to be delivered to multiple positions in the air-liquid mixing chamber simultaneously, increasing the contact area between liquid and air and improving mixing efficiency without significantly increasing overall device complexity.
2Reliability
If the cross-sectional area of the flow path in the tube body is reduced to improve air mixing efficiency, then foam homogeneity is improved, but the pressing force required to discharge foam increases
Solution Approach 1:
Instead of reducing the cross-sectional area of a single flow path, the invention segments the liquid delivery into multiple inlets with appropriate cross-sectional areas. This allows the total liquid flow to be distributed across multiple paths, maintaining adequate air-liquid contact area for homogeneous foam while preserving sufficient flow capacity to reduce pressing force requirements.
3Ease of manufacture
If the gap between pipe fixture and lid member inner wall is increased to facilitate assembly, then ease of manufacture is improved, but the cross-sectional area of air intake flow path increases causing excessive air flow and poor foam quality
Solution Approach 1:
The air intake is divided into multiple separate air inlets (first air inlet and second air inlet) positioned at different locations in the air-liquid mixing chamber. This segmentation allows each inlet to have controlled, smaller cross-sectional areas that sum to the required total air intake, while the individual inlets can be independently positioned to accommodate assembly variations without causing excessive overall air flow.

AI summary
Provided is a foam discharge container capable of discharging foam with uniform and stable quality. The foam discharge container is provided with a plurality of liquid introduction paths for introducing a foaming liquid into an air-liquid mixing chamber and a plurality of air introduction paths for introducing air thereinto, thereby making it possible to remarkably improve the air-liquid mixing efficiency and stabilize the supply amounts of the air and the foaming liquid without a large amount of liquid flowing into the air-liquid mixing chamber by one push. As a result, the foam discharge container can discharge foam with uniform and stable quality.
