Sheet Material Container Bulging Intermediate Extending Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet containers fail to ensure sufficient capacity and efficient discharge of contents due to limitations in design and structure, particularly in retaining shape and accommodating volume.
Innovation Solution
A sheet container design featuring a container body composed of laminated film layers with specific surface-like parts and filler enclosing parts, including an intermediate extending part that bulges outward, enhancing capacity and facilitating easy discharge by distributing pressure across a wider area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the container body is made with a simple sheet structure, then the manufacturing process is simple, but the inner space capacity is insufficient
Solution Approach 1:
The container body is divided into multiple surface-like parts (first surface-like part, second surface-like part, etc.) that adjoin and cross each other. Each part can be independently formed and attached, allowing the overall structure to achieve complex three-dimensional capacity while maintaining relatively simple individual components that are easier to manufacture.
Solution Approach 2:
The intermediate extending part extends in a direction perpendicular to the boundary part between surface-like parts, creating a bulging outward structure that utilizes the third dimension (depth/height) to increase inner space capacity without significantly increasing the footprint area of the container base.
2Stability of the object's composition
If the container body is made rigid to retain shape, then shape retention is improved, but the discharge of contents becomes difficult
Solution Approach 1:
The container body has different structural characteristics in different regions: the intermediate extending part creates localized bulging that provides shape retention and structural stability, while the overall flexible sheet structure maintains compliance for discharge. The film regions adjoining the intermediate extending part can deform locally to facilitate content discharge while the bulk structure maintains its shape.
3Volume of moving object
If the container body bulges outward to increase capacity, then inner space is maximized, but the discharge process becomes complex
Solution Approach 1:
The intermediate extending part structure is designed to automatically facilitate discharge through its geometric configuration. The bulging outward structure creates natural flow paths and pressure distribution that enable contents to be discharged easily without requiring complex mechanical discharge mechanisms or additional operational steps.

AI summary
A container body of the sheet container is composed of a sheet member given by lamination of a plurality of film layers, and has a plurality of surface-like parts; the plurality of surface-like parts include a first surface-like part and a second surface-like part that adjoin and cross each other; the sheet member has a filler enclosing part in which a filler is enclosed between the plurality of film layers; the filler enclosing part includes an intermediate extending part laid across the first surface-like part and the second surface-like part, and a first adjoining part and a second adjoining part that individually adjoin both sides of the intermediate extending part; and the intermediate extending part extending more further from the second surface-like part than the first adjoining part and the second adjoining part extend.
