Lay-Flat Pouch with Folded Base for Upright Standing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lay-flat pouches are unable to stand upright on a horizontal surface without secondary packaging, a gusset, or a support structure, and they are not suitable for products that cannot withstand retort processing.
Innovation Solution
A food package design featuring a lay-flat pouch with two separate compartments, where the pouch is folded and secured with a fastening member to create a base that allows the package to stand upright, and a method for loading products into these compartments with one compartment undergoing retort processing while the other does not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a lay-flat pouch is used without secondary packaging, gusset, or support structure, then the device complexity is reduced, but the pouch cannot stand upright on a horizontal surface
Solution Approach 1:
The pouch is divided into two separate compartments (first compartment and second compartment) that can be independently filled and processed. This segmentation allows each compartment to be optimized for specific functions while maintaining the overall simplicity of the pouch structure without requiring secondary packaging or support structures.
Solution Approach 2:
The pouch utilizes a folded configuration where the first and second portions of the pouch fold back upon themselves to create a base structure. This dimensional transformation converts a flat two-dimensional pouch into a three-dimensional structure capable of standing upright, eliminating the need for additional support elements.
2Reliability
If all compartments undergo retort processing, then sterilization is achieved, but products that cannot withstand high temperatures are damaged
Solution Approach 1:
The pouch is segmented into multiple compartments that can be independently processed. The first compartment can undergo retort sterilization while the second compartment remains unprocessed or undergoes different processing, allowing each compartment to be treated according to the specific requirements of its contents without exposing all products to harmful high temperatures.
Solution Approach 2:
Different compartments of the pouch are assigned different quality characteristics - the first compartment is designed for retort-processed products requiring sterilization, while the second compartment is designed for heat-sensitive products. This local differentiation of processing conditions allows each compartment to maintain the appropriate quality for its specific product type.
3Ease of manufacture
If a single compartment pouch is used, then the manufacturing process is simple, but storage efficiency and product preservation are limited
Solution Approach 1:
The pouch is divided into multiple compartments that can be independently filled with different products. This segmentation increases storage efficiency by allowing multiple products to be packaged in a single pouch, reducing the number of separate packages needed and improving space utilization during storage and transport.
Solution Approach 2:
Multiple compartments are merged into a single integrated pouch structure with common sealing and folding mechanisms. This merging maintains manufacturing simplicity while enabling enhanced storage efficiency, as the multiple compartments share common structural elements and can be processed as a unified package.

AI summary
A food package (100) includes a lay-flat pouch (11) and a fastening member (136). The lay-flat pouch has a first compartment (112) and a second compartment (114) defined by a first side seal (120) and an intermediate seal (116) extending from the first side seal. The pouch includes a fold seam (132) extending along the intermediate seal. The pouch is arranged in a folded configuration with the first compartment disposed adjacent to the second compartment and a first portion of the first side seal and a second portion of the first side seal cooperate to define a base of the pouch. The fastening member attaches the first compartment to the second compartment.
