Sheet Packaging Material with Inverted Trapezoidal Crease Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging materials for liquid food products do not optimize pallet filling efficiency while maintaining a visually appealing package form, particularly for products that need to be emptied by spooning, where the bottom area is larger than the top area.
Innovation Solution
A sheet packaging material with a multilayer structure and specific crease line configurations that form a sealed package with a top area larger than the bottom area, allowing easier emptying and optimized pallet filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the packaging material is folded and sealed to form a traditional package with larger bottom area than top area, then the package structure is stable and easy to manufacture, but the product cannot be easily emptied by spooning and pallet filling efficiency is reduced
Solution Approach 1:
The patent inverts the traditional package shape by making the top area larger than the bottom area. This inversion allows the package to be easily emptied by spooning while maintaining structural stability through the specific crease line configuration that creates a truncated cone shape with reinforced bottom.
2Productivity
If the package has larger bottom area than top area, then the package is stable and easy to manufacture, but the pallet filling efficiency is reduced
Solution Approach 1:
The patent employs asymmetric design in the crease line configuration, with different fold patterns on opposite sides of the package. This asymmetric folding creates a shape that optimizes both structural integrity and space utilization on pallets, improving filling efficiency while maintaining manufacturability.
3Shape
If the crease lines are configured for traditional folding, then the manufacturing process is simple, but the package form is not visually appealing and does not optimize pallet filling
Solution Approach 1:
The patent divides the packaging material into distinct regions with specific crease line patterns, creating modular folding sections. This segmentation allows for complex visual appeal and optimized pallet filling while keeping each individual fold simple and manageable during manufacturing.
