Film-Rigidifying Frame for Stand-Up Package Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food packaging solutions fail to maintain an upright position on shelves, lacking structural integrity to effectively display products while minimizing material weight and facilitating easy recycling.
Innovation Solution
A package design utilizing a thin plastics film sheet material with a film-rigidifying frame, where the frame is laminated to the film blank with printed artwork and folded to create rectangular walls, providing structural support without a rigid rear wall in one embodiment and including it in another, to form a box-like shape that stands upright.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If a thin plastics film sheet material is used to form the package walls, then material weight is minimized and recycling is simplified, but structural integrity and ability to maintain upright position is insufficient
Solution Approach 1:
The patent combines a thin plastics film sheet material with a film-rigidifying frame to create a composite structure. The frame provides structural support and rigidity while the thin film material maintains lightweight properties and facilitates recycling. This composite approach resolves the contradiction between weight minimization and structural integrity.
Solution Approach 2:
The patent uses a thin plastics film sheet material that is folded and formed to define the package walls, creating a flexible shell structure. This thin film approach minimizes material weight and simplifies recycling compared to traditional rigid packaging, while the film-rigidifying frame compensates for the inherent flexibility to provide necessary structural support.
2Stability of the object's composition
If a film-rigidifying frame is added to provide structural support, then upright position and display capability are improved, but device complexity increases
Solution Approach 1:
The patent merges the film-rigidifying frame with the thin plastics film sheet material by laminating or coupling them together. This integration allows the frame to be incorporated into the package structure without adding significant complexity, as the frame becomes part of the wall assembly rather than a separate component.
Solution Approach 2:
The film-rigidifying frame is designed with segmented construction, including a front panel, side panels, and rear panel that can be formed from a single sheet material and folded into position. This segmentation allows for simplified manufacturing and assembly while providing the necessary structural support for upright positioning.
3Manufacturing precision
If artwork is printed on the thin plastics film sheet material before folding, then display quality is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies artwork printing to the thin plastics film sheet material before folding and forming the package walls. This preliminary action allows for high-quality artwork reproduction on a flat surface, and the subsequent folding process maintains the printed artwork's integrity. The frame is then laminated or coupled to the printed film, creating a multi-layer structure that preserves both manufacturing ease and display quality.

Function Achieved in This Case
The solution enables the package to maintain an upright position on shelves, optimizing display while minimizing material weight and allowing for simplified recycling due to uniform plastics material composition.
Implementation Method 1
the film-rigidifying frame is coupled permanently using a suitable lamination or coupling process to an interior surface of a flat film blank

AI summary
A stand-up package is formed to include an interior region for containing a product. The package is configured to be in an upright, standing position. The stand-up package includes a film-rigidifying frame and a film pouch. The film-rigidifying frame is coupled to the film pouch so that the film pouch assumes an upright position.
