Collapsible Multi-Sleeve Storage Container for Bread Freshness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage solutions 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, where the sleeves engage through friction and optional features like 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 solutions like plastic wrap or 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 a nested sleeve structure where multiple cylindrical sleeves of decreasing diameters are inserted one inside another. The first sleeve has the largest diameter, the second sleeve has a smaller diameter that fits within the first, and the third sleeve has the smallest diameter fitting within the second. This nested arrangement creates multiple concentric sealing layers that progressively trap moisture and prevent air contact with the bread, significantly improving preservation effectiveness compared to single-layer wrapping.
Solution Approach 2:
The storage container is divided into multiple functional segments (three separate sleeves) rather than using a single wrapping layer. Each sleeve segment provides an additional barrier against air and moisture loss. The segmentation allows each layer to contribute independently to the sealing function, creating a cumulative protective effect that addresses the inadequacy of conventional single-layer wrapping.
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 types of bread
Solution Approach 1:
The nested sleeve design creates a universal storage solution that accommodates various bread types and sizes. The concentric cylindrical structure can adapt to different bread shapes (loaves, baguettes, rolls) by adjusting the insertion depth of each sleeve. The open-ended design allows flexible placement of bread items while maintaining the sealing function, making it versatile for storing different types of bread that conventional bags cannot handle effectively.
3Adaptability or versatility
If multiple sleeves of varying diameters are used, then the container can accommodate bread of different shapes and sizes, but the device complexity increases
Solution Approach 1:
The patent uses a nested sleeve configuration where three cylindrical sleeves of progressively smaller diameters are inserted one inside another. The first sleeve (largest diameter) contains the second sleeve, which in turn contains the third sleeve (smallest diameter). This nested arrangement provides a compact, space-efficient structure that accommodates various bread sizes while maintaining simplicity in the overall device design.
Solution Approach 2:
The sleeves are designed with dynamic engagement capabilities, allowing them to be inserted and removed flexibly. The sleeves can engage with each other through friction or mechanical features (such as ridges or grooves) that provide stable positioning while still allowing easy assembly and disassembly. This dynamic design enables the container to adapt to different bread sizes without requiring complex adjustment mechanisms.

Function Achieved in This Case
The container effectively prevents bread from drying out by minimizing exposure to air, accommodating various bread sizes and shapes, and allowing for easy access and collapse as needed.

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.
