Packing Member for Liquid Container Bag Rippling Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packing members for liquid containers fail to effectively prevent deformation and damage due to liquid rippling during transportation, and require shape changes when the container design is modified, leading to increased manufacturing costs and complexity.
Innovation Solution
A packing member design that includes a first and second section to sandwich the liquid container, with a pressurizing portion that increases the pressure within the container, tensioning the bag and preventing rippling, while allowing for a simpler configuration that does not necessarily match the container's outer shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the packing member is shaped in accordance with the outer shape of the liquid container, then the protection property is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The packing member is divided into a tray body and a separate pressurizing member that can be independently configured. The tray body provides basic shaping and protection, while the pressurizing member adds pressure to suppress liquid rippling. This segmentation allows the tray body to maintain a simple configuration while achieving effective protection through the combined action of the pressurizing member.
Solution Approach 2:
The pressurizing member acts as an intermediary element between the tray body and the liquid container bag. It transmits pressure to the bag to suppress liquid rippling without requiring the tray body itself to have a complex shape matched to the container. This intermediary approach decouples the protection function from the tray's geometric complexity.
2Reliability
If the packing member is shaped in accordance with the outer shape of the liquid container, then the protection property is improved, but the manufacturing cost increases
Solution Approach 1:
By separating the packing member into a simple tray body and an independent pressurizing member, the tray body can be manufactured using standard, cost-effective processes without requiring custom shaping to match each container design. The pressurizing member can be a simple component that provides the necessary pressure function.
Solution Approach 2:
The tray body is designed with universal, simple geometry that can accommodate different liquid container designs without requiring redesign. The pressurizing member provides the specific protection function against liquid rippling. This universal approach reduces manufacturing costs by avoiding custom tooling and design changes for different container configurations.
3Quantity of substance
If the volume of the bag is increased to increase the liquid capacity, then the liquid capacity is improved, but the size of the packing member increases accordingly
Solution Approach 1:
The pressurizing member is designed as a separate, removable component that can be optimized for applying pressure without requiring the entire packing member to scale with bag volume. This allows the tray body to maintain a compact size while the pressurizing member provides focused pressure application.
4Adaptability or versatility
If a structure is contained in the bag along with liquid, then the functionality is improved, but the damage and deterioration risk increases due to structure movement from liquid rippling
Solution Approach 1:
The invention converts the harmful effect of liquid rippling into a beneficial pressurization mechanism. By designing the pressurizing member to apply pressure that counteracts rippling forces, the same liquid movement that would normally damage internal structures is instead used to maintain pressure that stabilizes the bag and protects contained structures from damage and deterioration.

Implementation Method 1
a pressurizing portion that presses a region of a portion of the bag sandwiched between the first section and the second section such that, in a fixed state where the bag is fixed between the first section and the second section by the fixing portion, pressure in the liquid storage portion becomes higher than pressure before the fixed state is entered

AI summary
A packing member includes a first section arranged to face a first face of a flexible bag of the liquid container along a DW plane that includes the D direction and the W direction; a second section arranged to face a second face of the bag along the DW plane, and sandwiches the bag in the T direction in cooperation with the first section; a fixing portion that fixes the first section and the second section in a state of sandwiching the bag in the T direction; and a pressurizing portion that presses the region of a portion of the bag sandwiched between the first section and the second section in a fixed state where the bag is fixed between the first section and the second section by the fixing portion, such that pressure in the liquid storage portion rises.
