Liquid Supply Container Valve with Segmented Void for Gas Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid supply containers face inefficiencies in gas discharge during liquid filling, leading to prolonged and labor-intensive processes, and inadequate structures to prevent residual liquids from remaining within the container.
Innovation Solution
The design incorporates a cylindrical liquid inlet/outlet portion with a valve system, a holder member, and a seal member that divides the void portion into multiple sections, allowing for efficient gas discharge and minimizing liquid residue through a unique configuration of ribs or flange portions, ensuring the valve body separates from the seal member to facilitate open and closed states effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple valve structure is used without internal gas discharge paths, then the device complexity is reduced, but the gas discharge efficiency deteriorates causing prolonged filling time
Solution Approach 1:
The void portion is divided into multiple sections by ribs or flange portions, creating separate gas discharge paths. This segmentation allows gas to be discharged efficiently through multiple channels simultaneously, reducing filling time without requiring a completely complex valve structure.
Solution Approach 2:
The ribs or flange portions act as intermediary structures that guide gas flow from the storage portion to the outside through the void portion. These intermediate elements enable efficient gas discharge while maintaining a relatively simple overall valve design.
2Device complexity
If the void portion is left as a single continuous space, then the device complexity is reduced, but liquid residue increases due to poor gas discharge
Solution Approach 1:
By dividing the void portion into multiple sections using ribs or flange portions, the patent creates separate gas discharge pathways that prevent liquid from remaining in dead zones. This segmentation ensures complete gas discharge and minimizes liquid residue without significantly increasing structural complexity.
3Reliability
If the valve body is always sealed against the seal member, then the sealing reliability is improved, but the ease of operation deteriorates due to difficulty in opening
Solution Approach 1:
The valve body is designed to be movable relative to the seal member, transitioning between sealed and open states. This dynamic design maintains reliable sealing when closed while enabling easy opening when needed, balancing both reliability and operability through controlled movement rather than fixed positioning.

AI summary
A liquid supply container includes a liquid inlet/outlet portion forming member including a cylindrical portion attached to an opening end of a storage portion configured to contain liquid. An inlet/outlet portion of liquid for the storage portion is formed in the cylindrical portion, and an valve is disposed in the inlet/outlet portion. A valve body of the valve is movably accommodated in a holder member. The cylindrical portion of the liquid inlet/outlet portion forming member forms a void portion surrounding the holder member in a circumferential direction between the cylindrical portion and the holder member. A rib or a flange portion is provided for dividing the void portion into at least two portions in the circumferential direction or a moving direction of the valve body.
