Embossed Pouch Nozzle Rigidity and Fluid Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pouch containers with film shells lack stability, causing deformation that can block fluid paths in the nozzle, leading to inefficient refilling of liquid contents, and existing solutions either lack sufficient rigidity or increase the number of components and manufacturing processes.
Innovation Solution
The pouch container features embossed areas on the nozzle walls with plane, dot, or line shapes to provide desired rigidity, maintaining an open nozzle state without additional components, using a combination of embossment shapes to ensure stability against deformation and fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If emboss is formed on one shell member to give rigidity to the nozzle wall, then the rigidity of the nozzle wall is improved, but the emboss shape is simple and sufficient rigidity cannot be given to the nozzle wall
Solution Approach 1:
The invention applies different emboss patterns (first emboss along center line, second emboss on both sides, third emboss perpendicular to first emboss) to different local areas of the nozzle wall. Each emboss pattern provides rigidity in specific directions, and the combination of these localized embosses creates comprehensive rigidity throughout the nozzle structure without requiring a single complex emboss design.
2Strength
If another film formed with a rib is adhered to the shell member to give rigidity to the nozzle, then the rigidity of the nozzle is improved, but the number of components and manufacture processes increases
Solution Approach 1:
The invention merges the rigidity-providing function into the existing shell member by forming embosses directly on the pouch film raw material during the pouch manufacturing process. This eliminates the need for separate rib-formed films and their associated adhesion processes, reducing both the number of components and manufacturing steps while achieving the desired nozzle rigidity.
Solution Approach 2:
The shell member serves its own rigidity reinforcement need through the embosses formed on it. Instead of requiring an additional film component to provide rigidity, the shell member itself is structurally modified through embossing to provide the necessary stiffness, making the system self-sufficient.

AI summary
A pouch with a nozzle has a reliable dispensing opening. The pouch holds liquid contents. The pouch has a shell portion formed by sealing two plies of plastic together to form a pouch volume and a nozzle portion which communicates with the inside of the shell portion. The nozzle portion is formed by a series of embossments which form a reliably open passage for dispensing fluid. Three sets of embossments include a plane shape, a dot shape or a line shape.
