Multi-Sleeve Collapsible Container for Bread Freshness Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage methods for bread, such as plastic wrap and aluminum foil, fail to effectively prevent bread from drying out, and existing bags do not provide a perfect solution for all types of bread.
Innovation Solution
A collapsible storage container with multiple sleeves of varying diameters and lengths, featuring frictional engagement, concentric ridges, thread patterns, or gaskets to inhibit air passage and maintain freshness, accommodating bread of different shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional storage methods (plastic wrap, aluminum foil) are used, then the bread can be wrapped and stored, but they fail to effectively prevent bread from drying out
Solution Approach 1:
The patent employs nested sleeves where smaller sleeves are placed inside larger sleeves, creating multiple concentric barriers. This nested structure provides layered protection against air exposure and drying, with each sleeve acting as an additional barrier that enhances overall preservation effectiveness compared to single-layer conventional methods.
Solution Approach 2:
The patent uses flexible plastic sleeves with sealed ends that conform to the bread shape while providing an airtight barrier. These flexible shells prevent air contact with the bread surface, effectively stopping the drying process while allowing the container to adapt to different bread sizes and shapes.
2Reliability
If bags are used to store bread, then some delay to bread drying out is achieved, but they are not a perfect solution for all bread
Solution Approach 1:
The patent creates a universal storage system using multiple sized sleeves that can accommodate various bread types including loaves, baguettes, and rolls. The nested sleeve design allows the same container system to adapt to different bread shapes and sizes, providing versatile protection that works for all bread types rather than requiring type-specific containers.
Solution Approach 2:
The patent divides the storage container into multiple segmented sleeves of different sizes. This segmentation allows selective use of appropriate sleeve sizes for different bread types, with the ability to nest smaller sleeves inside larger ones. This segmented approach provides tailored protection for each bread type while maintaining a unified container system.
3Adaptability or versatility
If multiple sleeves of varying diameters are used, then various bread sizes and shapes can be accommodated, but the device complexity increases
Solution Approach 1:
The patent simplifies the overall structure by nesting smaller sleeves within larger sleeves, creating a compact hierarchical arrangement. This nesting approach allows multiple sized containers to be stored together in a space-efficient manner, reducing the footprint when not in use while maintaining the ability to provide size-appropriate protection for different bread types.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The container effectively maintains bread freshness by restricting air exposure, accommodating various bread sizes and shapes, and allowing for easy access and collapse as bread is consumed.
Implementation Method 1

AI summary
Various aspects of the disclosure generally relate to a collapsible storage container with multiple sleeves. In some implementations a two-sleeve variant is described. In some implementations a three-sleeve variant is described. Both variants may be used to contain appropriately sized and shaped objects, for example bread, maps, posters, blueprints, plans, etc.
