Resealable Container Tab Positioning for Easy Reopening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resealable containers for consumer goods, such as cigarette packs, are difficult to reopen after the initial opening due to the tab being hidden underneath the lid, making it hard to access the contents again.
Innovation Solution
A container design featuring a hinged lid with an inner package that includes a sealing flap and a tab positioned below the lid edge, allowing for easy initial opening and subsequent re-opening, with the tab moving outside the container to provide leverage for easier access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the tab is positioned underneath the lid to maintain a compact closed container, then the container appears neat and compact, but the tab becomes difficult to access for reopening
Solution Approach 1:
The tab extends beyond the front wall of the box in the vertical dimension, creating a multi-level structure where the tab protrudes forward from the container face. This dimensional extension allows the tab to be accessible for pulling while maintaining container compactness when closed, as the tab extension is minimal and does not significantly increase the overall container footprint.
2Ease of operation
If the access opening is made larger to improve access to contents, then easier access to goods is achieved, but the sealing effectiveness may be compromised
Solution Approach 1:
The sealing flap is configured with differentiated zones: a larger main body portion that covers the majority of the access opening to maintain sealing effectiveness, and a smaller tab extension that protrudes for pulling functionality. This local differentiation allows the sealing surface area to remain large for effective sealing while providing a dedicated small region (the tab) for easy manipulation and opening.
3Ease of operation
If a tab is added to facilitate opening, then opening ease is improved, but the device complexity increases
Solution Approach 1:
The tab is integrated as an extension of the sealing flap itself, merging the sealing function and the opening assistance function into a single unified component. This eliminates the need for separate tabs or additional mechanical opening mechanisms, thereby improving opening ease while minimizing increases in structural complexity.

AI summary
A container comprises a housing that comprises a box and a lid that is hingedly attached to the box. The lid comprises a bottom edge. The box comprises a front wall and a rear wall. The container also comprises an inner package disposed at least partially within the housing and at least partially defining an interior volume for housing consumer goods. The inner package is configured to open and close when the lid of the housing is opened and closed. The inner package comprises an access opening and a sealing flap. The sealing flap comprises a tab that has a bottom edge. The bottom edge of the tab is positioned below the bottom edge of the lid when the lid is in a closed position.
