Food Package With Negative Draft Wall for Stable Vertical Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food packaging solutions fail to provide stable vertical display and efficient stacking while maintaining freshness, especially for perishable items, as they often tip over when oriented vertically and are not designed for versatile stacking configurations.
Innovation Solution
A re-closable food package with a container and lid that features a negative angled front wall, a horizontal rim, and a lip for stable vertical display and nesting, allowing the package to snap shut and maintain freshness, while also enabling horizontal stacking through complementary base and lid design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the package is designed for vertical display, then consumer visibility is improved, but the package tips over when oriented vertically
Solution Approach 1:
The front wall is designed with a negative angle relative to the base, creating an asymmetric structure that shifts the center of mass forward. This asymmetric geometry allows the package to rest stably on the shelf surface when oriented vertically, preventing tipping while maintaining consumer visibility of the front face.
Solution Approach 2:
A lip is added to the front surface of the base, creating a new geometric feature that interacts with the shelf surface. This additional dimensional element provides a stopping point that prevents the package from rolling forward, enabling stable vertical display orientation.
2Reliability
If the package is designed for stable vertical display, then display effectiveness is improved, but stacking efficiency is reduced
Solution Approach 1:
The package structure incorporates features that serve multiple functions: the negative angled front wall and lip provide stable vertical display, while the flat rear surface and overall geometry enable efficient horizontal stacking. This multi-functional design allows the same package to excel at both vertical display and horizontal stacking without compromise.
Solution Approach 2:
The package geometry is designed to nest efficiently with adjacent packages when stacked horizontally. The flat surfaces and standardized dimensions allow packages to be stacked in tight configurations, maximizing storage and shipping efficiency while maintaining the stable vertical display capability.
3Ease of operation
If the package allows easy opening, then consumer convenience is improved, but freshness maintenance is compromised
Solution Approach 1:
The package is divided into two separate components: a removable lid and a base. This segmentation allows the consumer to easily open the package by lifting the lid while maintaining the ability to re-close it by placing the lid back on the base, thus preserving freshness after opening.
Solution Approach 2:
The lid is designed to be temporarily removed for access to the foodstuff, then recovered and placed back on the base to seal the package. This reversible action allows convenient access while maintaining the protective seal for freshness preservation.

AI summary
Packages for the stable display and storage of foodstuffs. Re-closeable foodstuff package are provided that include a container and a lid. A front wall has a negative draft angle to the base of the container. The negative draft angle of the wall and a rim of the container enable the package to be displayed in a vertical or near vertical orientation. Additionally, a lip and front edge near the base of the container allows the packages to be stacked stably while in a horizontal position to allow for easy shipping of quantities of the packages to stores for sale.
