Double Pressurized Container Sealing and Discharge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double pressurized containers face issues such as accidental discharge during distribution, vulnerability to impact, and inefficiencies in the manufacturing process, including time-consuming concentrate charging and potential leaks.
Innovation Solution
A double pressurized container design featuring an outer and inner container made of synthetic resin, with a flexible inner container and a plug that seals both containers. The plug has an openable seal part that can only be opened by a dedicated discharge member, enhancing safety and preventing accidental discharge. The container's design also includes features like a flange and annular disk part to prevent mixing of the pressurizing agent with the concentrate and to secure the plug effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a valve with dip tube is used to open the container, then the valve can be used repeatedly and manufacturing cost is reduced, but the tip end is easily shifted from the sealed part position by dip tube curvature and the dip tube bends easily causing operational difficulties
Solution Approach 1:
The patent removes the dip tube component entirely and replaces it with a direct valve-to-container sealing mechanism. The valve body directly contacts the container opening without an intermediate dip tube, eliminating the curvature and bending issues that caused operational problems while maintaining repeatable use and cost-effectiveness.
2Ease of manufacture
If the container is made of synthetic resin to reduce weight and cost, then manufacturing cost and weight are reduced, but the container may be destroyed or contents may leak when dropped during distribution
Solution Approach 1:
The patent incorporates a cushioning layer or shock-absorbing structure within the container design that activates upon impact to prevent destruction and leakage. This protective mechanism is built into the synthetic resin container structure beforehand, allowing the material to remain lightweight and cost-effective while gaining enhanced drop resistance during distribution.
3Adaptability or versatility
If the inner container is filled with concentrate and the space between inner and outer containers is filled with pressurizing agent, then the product achieves double pressurization functionality, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The patent combines the charging of concentrate and pressurizing agent into a single integrated manufacturing process step. Rather than separately filling the inner container with concentrate and then filling the annular space with pressurizing agent, the process merges these operations to achieve double pressurization functionality while reducing manufacturing complexity and time.
4Reliability
If a plug is used to seal both outer and inner containers, then accidental discharge during distribution is prevented, but the manufacturing process requires additional sealing steps
Solution Approach 1:
The patent designs the plug as a multi-functional sealing component that simultaneously seals both the outer container opening and the inner container opening. This single plug structure performs multiple sealing functions that would otherwise require separate sealing mechanisms, preventing accidental discharge during distribution while managing sealing complexity through integrated design.
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 provides high safety during distribution by preventing accidental discharge and enhancing impact resistance. It also simplifies the manufacturing process, reduces the risk of leaks, and allows for efficient charging of the concentrate and pressurizing agent.
Implementation Method 1
the inner container contracts by dissolving gas to the concentrate
Implementation Method 2
the pressurizing agent permeates through the inner container into the concentrate

AI summary
A method for manufacturing a discharge product includes the steps of: preparing the double pressurized container including an outer container; an inner container stored inside the outer container and having flexibility; and a plug for sealing both of the outer container and the inner container; charging a concentrate inside the inner container; contracting the inner container before or after charging the concentrate; tightly mounting the plug to a mouth of the inner container; charging the pressurizing agent between the outer container and the inner container through a space between a mouth of the outer container and the mouth of the inner container; and tightly closing the space between the mouth of the outer container and the mouth of the inner container by the plug.
