Two Fluid Discharge Container With Integrated Piston
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-fluid discharge containers face challenges in maintaining a consistent discharge ratio due to differences in viscosity between contents, and often result in bulky designs or difficulty in dispensing viscous materials, especially when using integrated pistons or pressurizing agents.
Innovation Solution
A two-fluid discharge container design featuring a container body partitioned by a piston into separate storage portions for each content, with a pressurizing space and valve assembly that allows simultaneous pressurization and discharge of both contents using a single integrated piston, ensuring equal discharge ratios and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two independent pistons are used to push out two contents, then each content can be pressurized independently, but the discharge amount ratio cannot be controlled and differs due to viscosity variations
Solution Approach 1:
The patent combines two independent pistons into a single integrated piston that simultaneously pressurizes both contents. This integrated piston has a first pressing portion for the first content and a second pressing portion for the second content, ensuring that both contents are discharged in equal amounts regardless of viscosity differences, thereby achieving precise discharge ratio control while maintaining independent pressurization capability
2Manufacturing precision
If an integrated piston is used to push out two contents simultaneously, then equal discharge amounts are achieved, but the device becomes bulky as the piston protrudes to the exterior
Solution Approach 1:
The patent nests the integrated piston within the container body such that the piston does not protrude to the exterior. The piston is positioned inside the container with its pressing portions acting on the contents from within, eliminating the need for external protrusion while maintaining the equal discharge capability. This nested configuration achieves compact device design without sacrificing discharge precision
3Productivity
If a pressurizing agent is used to push the integrated piston, then viscous materials can be discharged, but the pressurizing agent structure becomes complex
Solution Approach 1:
The patent extracts the pressurizing agent from the container body, positioning it separately so that it does not occupy space within the container. The pressurizing agent is configured to push the integrated piston without requiring complex internal structures within the container body, thereby enabling viscous material dispensing while maintaining simple device structure
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
The solution enables easy and consistent discharge of contents at a constant ratio, even with varying viscosities, while maintaining a compact design and effectively handling viscous materials without the need for specific pressurizing agent structures, and can be adapted for three or more fluid discharge.
Implementation Method 1
a piston (12) which partitions the container body (11) into a first storage portion (14) in which a first content (18) is filled, a second storage portion (15) in which a second content (19) is filled, and a pressurizing agent housing portion (16)
Implementation Method 2
by the pressure of the pressurizing agent, the second piston is pushed applying a pressure to the second chamber

AI summary
Provided is a two fluid discharge container comprising: a container body (11); a piston (12) partitioned by a first storage part (14) and a second storage part (15), which are accommodated in the container body and are each to be filled with content, and a pressurized space (20) to be filled with a pressurizing agent; and a valve mechanism (21) that closes an opening in the container body, and has a passage through which the first storage part and the second storage part communicate. The first storage part and the second storage part are concentrically formed, and the contents of the first storage part and the second storage part are simultaneously pressurized by the piston so as to be discharged.
