Transformable Kebab Bag with Folded Corners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging methods for kebabs, such as paper bags and aluminum foil, are complex and resource-intensive, particularly for on-site consumption and take-away, and existing transformable bags are difficult to prepare and package efficiently.
Innovation Solution
A bag designed to fold into a compact state for preparation and unfold for packaging, featuring a front and back part connected by a tab, with a folded edge and corner design that reduces volume and allows secure handling, and can be easily closed using the tab after filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If aluminum foil is used for take-away packaging, then the snack can be packaged for take-away, but the production is energy-intensive and resource-consuming
Solution Approach 1:
The patent replaces energy-intensive aluminum foil with disposable paper bags that can be transformed between folded and unfolded states. The paper material requires significantly less energy to produce while maintaining the necessary packaging functionality for both on-site consumption and take-away scenarios.
Solution Approach 2:
The patent changes the physical state parameter of the packaging from rigid aluminum foil to flexible paper that can transform between folded and unfolded configurations. This parameter change enables the same packaging to serve multiple purposes (on-site and take-away) while reducing production energy requirements.
2Adaptability or versatility
If existing transformable bags are used, then the bag can be transformed between folded and unfolded states, but the preparation and packaging process is relatively complicated
Solution Approach 1:
The patent divides the bag into distinct functional segments: a bottom section that folds over, corner sections that can be folded independently, a front part, and a back part with a tab. This segmentation allows each part to perform its specific function independently, simplifying the overall transformation process compared to complex integrated designs.
Solution Approach 2:
The patent inverts the conventional approach by having the bottom section fold over the top rather than the top folding down. This inversion, combined with the corner folding mechanism, creates an intuitive transformation sequence that reduces preparation complexity while maintaining versatility.
3Volume of moving object
If the bag is folded to reduce volume, then the bag is compact for storage, but the corners need to be folded securely for handling
Solution Approach 1:
The patent incorporates corner folding as a preliminary action that is performed before final handling. By pre-folding the corners in a specific manner during the bag preparation, the design ensures that the folded corners provide secure grip points for handlers without requiring additional manipulation during use.
Solution Approach 2:
The patent implements a nested folding structure where the corners are folded within and along with the bottom section. This nested arrangement allows the corners to be securely integrated into the folded configuration, providing both compact volume and secure handling points simultaneously.

AI summary
The invention relates to packaging for a snack, in particular a doner kebab, in the form of a bag (1) which is folded for preparing the snack and can be transformed from the folded state to an unfolded state for packaging the snack, wherein the bag (1) has a front part (2) and a back part (3) with a flap (4) that form a pocket (10) which can be closed by means of the flap (4). The folded state of the bag (1) is characterized in that a bottom section (7) of the pocket (10) is folded over along a fold (6), and two corners (9) located at the ends of the fold (6) are folded over.
