Reusable Silicone Baguette Packaging with Foldable Envelope
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for transporting bread, such as paper or plastic bags, are not reusable indefinitely and can release chemical compounds over time, posing hygiene and preservation issues.
Innovation Solution
A reusable packaging made of silicone material with a longitudinal envelope design, featuring a first closure system at the opening and a second securing system to maintain the envelope in a folded or rolled state, ensuring long-term usability and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper or plastic bags are used for transporting bread, then the packaging is disposable and easy to manufacture, but it cannot be reused indefinitely and releases chemical compounds over time
Solution Approach 1:
The patent changes the material parameter from conventional plastic or paper to silicone material, which fundamentally alters the chemical stability and reusability characteristics. The silicone material enables indefinite reuse without chemical release, directly resolving the contradiction between reusability and harmful factor generation.
Solution Approach 2:
The envelope is constructed from silicone material representing a composite solution that combines the benefits of flexibility, heat resistance, and chemical inertness. This material choice enables the packaging to be reused indefinitely without releasing chemical compounds into the food.
2Reliability
If conventional plastic packaging with zip closure is used, then the packaging is reusable and provides hygiene, but it still cannot be reused indefinitely and releases chemical compounds
Solution Approach 1:
The patent changes the material parameter from conventional plastic to silicone, which extends the duration of reusable action indefinitely. The silicone material maintains hygiene preservation through its chemical inertness and resistance to degradation, allowing the packaging to be reused without limit.
3Adaptability or versatility
If the envelope is made very long to accommodate multiple baguettes, then it can contain one or more bread sticks, but it becomes difficult to store when not in use
Solution Approach 1:
The patent applies segmentation by dividing the long envelope into functional zones: a first system for closing the opening and a second system for securing the folded/rolled state. This segmentation allows the envelope to be easily folded or rolled into compact sections for storage while maintaining the capacity to accommodate multiple baguettes when extended.
Solution Approach 2:
The envelope transitions from a static long structure to a dynamic form that can be folded or rolled into compact configurations for storage, then extended again for use. The second securing system enables this dynamic transformation, allowing the same envelope to serve both as a long container for multiple baguettes and as a compact stored item.

AI summary
The invention consists of a reusable packaging (2) for the transport of food product(s) (4), comprising an envelope (6) extending along a longitudinal direction (K) and with an opening (8), suitable for receiving, via said opening, said food product(s); the envelope (6) is made of silicone material and extends along the longitudinal direction (K) over a length greater than three times, preferably five times, the average width of said envelope.
