Soft Packaging Container Filler Confining Portion Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing soft packaging containers with filler confining portions are complex and difficult to produce, requiring multiple sheets and joining steps, which complicates the manufacturing process and makes it challenging to ensure sufficient sealability.
Innovation Solution
A method involving overlaying, forming, folding, and cutting of sheets to create a filler confining portion and an accommodating portion, allowing for the efficient production of soft packaging containers with multiple filler confining regions, using a series of steps including overlaying, forming, folding, and cutting of sheets to create a filler confining portion and an accommodating portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a filler confining portion is provided in more regions to increase rigidity, then the soft packaging container can stand independently, but the manufacturing process becomes more complex and difficult
Solution Approach 1:
The patent combines the filler confining portion with the accommodating portion by using a single continuous sheet structure. The opposing portions of the sheet are joined to form both the filler confining region and the accommodating region in an integrated manner, eliminating the need for separate components and reducing manufacturing complexity while maintaining rigidity through multiple filler confining regions
2Strength
If more sheets and joining steps are used to create filler confining portions, then the soft packaging container can stand independently, but it becomes difficult to ensure sufficient sealability
Solution Approach 1:
The patent merges the filler confining portion and accommodating portion into a single integrated structure formed from one continuous sheet. This reduces the number of joining interfaces between separate sheets, thereby minimizing potential sealing failure points while still providing multiple filler confining regions for adequate rigidity and independent standing capability
3Object-affected harmful factors
If the filler confining portion is separated from the accommodating portion to prevent mixing, then filler and content remain separate, but the manufacturing process requires more sheets and joining steps
Solution Approach 1:
The patent segments the sheet structure to create distinct filler confining portions and accommodating portions within a single continuous sheet. The opposing portions are joined to form separated regions that prevent filler-content mixing, while the integrated single-sheet construction avoids the complexity of multiple separate sheets and reduces joining steps

AI summary
A method for manufacturing an intermediate material for a soft packaging container according to the present invention includes: a first overlaying step P1 of laying a second raw film sheet 120 over a first raw film sheet 110; a confining portion forming step P2 of forming a filler confining portion 50 for confining a filler 59, the filler confining portion 50 being constituted by a non-joined region between the first raw film sheet 110 and the second raw sheet 12, by joining a portion of the first raw film sheet 110 and a portion of the second sheet 12 to each other; a folding step P4 of folding the first raw film sheet 110 and the second sheet 12 with the first raw film sheet 110 on an outer side, such that the filler confining portion 50 is present in a state where an inner portion thereof is continuous on two sides that are connected via at least one folding position; an accommodating portion forming step P5 of forming an accommodating portion 60 by joining a plurality of portions including at least one of the first raw film sheet 110 and the second sheet 12; and a cutting step P6 of forming an intermediate material A1 for a soft packaging container by cutting at least the first raw film sheet 110. This configuration makes it possible to more readily and reliably manufacture a soft packaging container that has a filler confining portion in more regions.
