Standing Pouch Base Formation via Corner Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current standup bag designs require complex and expensive technology to produce the base, making them costly and inefficient to manufacture.
Innovation Solution
A three-side seal standing pouch is created by folding a single sheet of packaging material and compressing corners inward to form a base, with a cap on the folded side, allowing the pouch to stand, and can be produced using a vertical form fill seal machine, reducing the need for sophisticated equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple separate sheets of packaging material are sealed together to form a base, then the pouch can stand, but the production process becomes complex and expensive
Solution Approach 1:
The patent merges multiple packaging sheets into a single integrated structure by sealing them together along edges to form a tube, then sealing the ends to create a single-piece standing pouch. This eliminates the need for separate base formation operations and reduces production complexity while maintaining the standing ability through the sealed tube structure.
Solution Approach 2:
The patent segments the packaging material into a tube structure by sealing three edges while leaving one edge open, then forms the base by folding and sealing the open edge. This segmentation approach allows for simplified production using standard vertical form fill seal equipment while achieving the standing function through the tubular configuration.
2Stability of the object's composition
If multiple complicated seals are made along the base to form a standing structure, then the pouch can stand, but manufacturing costs increase
Solution Approach 1:
The patent uses a single continuous sealing operation that serves multiple functions: it creates the tubular structure, forms the base, and enables the standing ability all in one process. This multi-functionality eliminates the need for separate base formation operations and reduces manufacturing costs by utilizing standard vertical form fill seal equipment for the entire process.
Solution Approach 2:
The tubular structure formed by sealing three edges automatically provides the framework for standing ability, and the remaining open edge is simply folded and sealed to complete the base formation. The structure essentially forms itself through the sealing process, reducing the need for additional complex manufacturing steps and equipment.
3Device complexity
If a single sheet is folded and sealed along three edges to form a tube, then production is simplified, but the base formation requires additional steps
Solution Approach 1:
The patent performs preliminary sealing of three edges to form the tubular structure before final base formation. This preliminary action creates a stable framework that simplifies the final base formation step, allowing the open edge to be simply folded and sealed without requiring complex additional equipment or processes, thereby maintaining high production efficiency.

AI summary
A flexible standing pouch made from a single sheet of packaging material having a fitment with a flat flange for mounting cap or dispensing device sealed onto a folded edge forming the top of the package, seams on each side and a bottom formed by turning the opposing corners of the bottom of the flat package downward, compressing them and turning them inward to form a flat bottom.
