Peelable Resealable Packaging With Chevron Seal Tip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for food products lack intuitive and easy-open, resealable features that allow for multiple serving applications while maintaining product freshness and convenience.
Innovation Solution
A package design featuring a flexible film sealed to a semi-rigid bottom portion with a central pull tab and a multi-sided seal that intersects to form a chevron tip, allowing easy peeling and resealing, facilitated by laser scores for reduced opening force and intuitive access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional seal design is used, then the package structure is simple, but the package requires high opening force and lacks intuitive access
Solution Approach 1:
The seal is segmented into multiple straight sides that intersect to form a chevron tip, creating distinct geometric regions. This segmentation allows the seal to be opened in a controlled manner along predetermined lines, reducing the force needed to initiate opening while maintaining seal integrity during storage
Solution Approach 2:
The seal geometry is pre-configured with intersecting straight sides forming a chevron tip that creates a stress concentration point. This preliminary geometric arrangement ensures that when force is applied to the chevron tip, the seal opens predictably along the intended path, making the opening action intuitive and requiring less force
2Ease of operation
If a complex seal geometry is used, then the package provides easy opening, but the manufacturing complexity increases
Solution Approach 1:
The seal employs local quality variation through its multi-sided geometry, where each straight side and intersection point serves a specific function. The chevron tip region is locally optimized for opening initiation, while other segments maintain seal integrity. This localized functional differentiation achieves complex opening behavior without requiring complex manufacturing processes
Solution Approach 2:
The seal uses asymmetric geometry with a chevron tip formed by intersecting straight sides at specific angles. This asymmetric design creates a preferred opening direction and path, making the package easy to open in the intended direction while maintaining manufacturing simplicity through straightforward geometric construction

AI summary
A resealable package includes a bottom portion defining an interior and including a sealing surface extending about a top of the interior; a film coupled to the bottom portion along at least a portion of the sealing surface and including a tab portion extending inward from one side of the top film; and a seal disposed between the film and the bottom portion and including at least first and second sides that intersect and form a seal portion tip. The seal seals the film to the bottom portion such that the film is configured to be resealably peeled away from the bottom portion along at least a portion of the seal area upon application of a force to the seal tip portion via the tab portion.
