Prism-Shaped Snack Box With Segmented Dispensing And Re-Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snack food packaging designs fail to effectively control portioning, sharing, and dispensing of contents without touching the remaining food, and often lack re-sealable options.
Innovation Solution
A prism-shaped box design featuring a blank with multiple foldable panels, including pull tabs and adhesive strips, allowing for efficient folding into a sealed box with a dispensing opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a box with open top is used for dispensing snack foods, then the dispensing function is achieved, but portion control and sharing control become difficult
Solution Approach 1:
The box is divided into multiple panels (first panel through ninth panel) that can be independently folded and sealed. The perforated opening is segmented from the main body, allowing controlled access while maintaining portion integrity. This segmentation enables the box to transition from a simple open container to a controlled dispensing system.
Solution Approach 2:
The box incorporates dynamic elements including foldable panels, pull tabs, and adhesive strips that allow the structure to change from a static open box to a dynamic sealed container. The pull tab mechanism enables repeated opening and closing, transforming the dispensing experience from uncontrolled to controlled while maintaining ease of use.
2Ease of operation
If a perforated opening is provided for dispensing, then access to contents is enabled, but re-sealing capability is lost
Solution Approach 1:
The adhesive strip is pre-applied to the interior surface of the ninth panel, preparing the re-sealing mechanism in advance. When the user closes the box after dispensing, the adhesive strip automatically bonds the panels together, providing reliable re-sealing without requiring additional user action. This preliminary preparation ensures both access and re-sealing capabilities are maintained.
Solution Approach 2:
The perforated opening allows the user to discard excess packaging material while recovering the integrity of the main box structure. The adhesive strip enables the box to be recovered to its sealed state after dispensing, allowing repeated use while maintaining food safety and portion control.
3Reliability
If multiple flaps and panels are added for sealing, then re-sealing capability is improved, but manufacturing complexity increases
Solution Approach 1:
The ninth panel serves multiple functions: it provides structural closure, contains the adhesive strip for re-sealing, and works with the pull tab mechanism to enable controlled access. This multi-functionality reduces the need for separate components, simplifying manufacturing while maintaining reliable sealed structure.
Solution Approach 2:
The sealing mechanism is merged into the existing panel structure rather than being a separate addition. The adhesive strip is integrated onto the ninth panel's interior surface, and the pull tab is formed from the same material as the panels themselves. This merging reduces manufacturing steps and complexity while achieving reliable sealing.
4Shape
If a prism-shaped design is used, then brand distinction is improved, but folding complexity increases
Solution Approach 1:
The box employs asymmetric panel configurations where the first through eighth panels are mirror images of each other, creating the characteristic prism shape. This asymmetry in the blank layout allows the panels to fold into a three-dimensional prism while maintaining manufacturing simplicity through repeated patterns.
Solution Approach 2:
The blank transitions from a two-dimensional flat pattern to a three-dimensional prism shape through controlled folding along predetermined lines. The mirror-image panel arrangement in the blank is designed to collapse into a compact three-dimensional form, achieving the prism shape without excessive folding complexity.
