Liquid Storage Container Bellows and Double-Folded Portion Inflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid storage containers face difficulties in achieving sufficient inflation within external containers, leading to a decrease in interior volume, due to insufficient inflation methods.
Innovation Solution
A liquid storage container design featuring a bag body composed of an inner and outer bag, heat-sealed together, with accordion-folded bellows portions and specific folding patterns to ensure optimal inflation, including a double-folded portion and triangular folded portions, allowing for secure inflation within the external container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid storage container is folded into a compact configuration and inserted into an external container, then the container can be easily housed and transported, but it becomes difficult to sufficiently inflate the container within the external container
Solution Approach 1:
The bag body is divided into multiple bellows portions (first, second, third bellows portions) with different folding configurations. The first bellows portion has a first folding pattern, the second bellows portion has a second folding pattern, and the third bellows portion has a third folding pattern. This segmentation allows each portion to expand in a controlled manner, ensuring sufficient inflation while maintaining compact storage.
Solution Approach 2:
The patent introduces a double-folded portion that extends in the width direction of the bag body, creating a multi-dimensional folding structure. This double-folded portion with different folding patterns from the bellows portions enables the container to expand not only in length but also in width, achieving sufficient three-dimensional inflation within the external container.
2Device complexity
If the liquid storage container is insufficiently inflated within the external container, then the folding configuration may be simpler, but the interior volume of the container decreases
Solution Approach 1:
The bag body is segmented into multiple functional portions (first bellows portion, second bellows portion, third bellows portion, and double-folded portion), each with specific folding patterns. This segmentation ensures that when the container is inflated, each portion contributes to the overall volume expansion, maximizing the interior volume while maintaining a manageable folding structure.
Solution Approach 2:
Different portions of the bag body are given different local folding qualities - the bellows portions have accordion-like folding patterns for controlled expansion, while the double-folded portion has a different folding pattern that allows it to expand in the width direction. This local differentiation ensures optimal volume utilization throughout the entire container.
3Ease of manufacture
If the bag body has uniform folding patterns throughout, then the manufacturing process is simpler, but the inflation performance is insufficient
Solution Approach 1:
The manufacturing process is segmented into distinct steps for creating different folding patterns in different portions of the bag body. The first bellows portion is formed with a first folding pattern, the second bellows portion with a second folding pattern, and the third bellows portion with a third folding pattern. This segmented approach allows each portion to be manufactured with its specific folding configuration while maintaining overall process feasibility.
Solution Approach 2:
The patent applies local quality by giving different folding patterns to different portions of the bag body during manufacturing. The double-folded portion is specifically formed with folding patterns different from the bellows portions, allowing it to expand differently during inflation. This localized differentiation improves inflation performance without making the overall manufacturing process prohibitively complex.

AI summary
A liquid storage container which can be securely inflated within an external container. The liquid storage container includes a bag body and an ejection outlet. The bag body includes a plurality of bellows portions formed by accordion-folding the bag body along longitudinal crease lines, and has a double-folded portion formed by folding the bag body along an upper lateral crease line and a lower lateral crease line. With reference to the bag body, the following relations are satisfied: 10%<X/H<50%, 3%<Y/H<10%, where H is the length of the bag body, x is the distance between the top periphery and the lower lateral crease line, and Y is the distance between the upper lateral crease line and the lower lateral crease line.
