Resealable Snack Package With Rigid Sidewalls And Peelable Flap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snack packages are difficult to open and reseal, leading to spills, product damage, and an unsatisfactory consumer experience due to their design, which lacks structural support and efficient resealing mechanisms, resulting in premature staling and spoilage.
Innovation Solution
The introduction of structurally rigid sidewalls and a resealable flexible flap with a raised pull tab allows for easy opening and resealing, maintaining the package's thickness and integrity, while the adhesive on the flap ensures secure closure without crushing the contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional end seam opening is used, then the package can be opened, but the package opens dramatically causing contents to spill and the eating experience is not discreet or clean
Solution Approach 1:
The package opening is segmented into a defined aperture and a flexible flap that can be peeled back independently. The aperture provides a controlled opening while the flap can be positioned to allow discreet access to contents without requiring the entire package to open, preventing spills and maintaining cleanliness.
Solution Approach 2:
A flexible flap with adhesive acts as an intermediary between the package opening and the contents. The flap can be peeled back to reveal the aperture for accessing contents, then repositioned and adhered to close the opening, providing a controlled interface that prevents direct exposure and potential spilling.
2Reliability
If adhesive reclosure means is used, then the package can be reclosed to preserve freshness, but the consumer must push down along all three edges of the adhesive which could crush the contents
Solution Approach 1:
The adhesive is applied locally only to the flexible flap rather than along all three edges of the package opening. This localized adhesive application on the flap alone provides sufficient reclosure capability without requiring pressure distribution along the entire perimeter, eliminating the risk of crushing contents through excessive pressing.
3Stability of the object's composition
If rigid sidewalls are added to maintain package thickness, then the package structure is improved, but the device complexity increases
Solution Approach 1:
The package utilizes a flexible film structure with integrated rigid sidewall elements that maintain package thickness and shape while preserving flexibility. The rigid sidewalls are incorporated into the flexible packaging structure, providing structural support without requiring a completely rigid container, thus balancing structural integrity with manufacturing simplicity.

AI summary
A resealable package, in an embodiment, comprises rigid sidewalls, and a resealable flexible flap having a raised pull tab for use by a consumer to peel open the bag by separating this flap from the front of the bag, and then resealing the bag by laying the flap back over the opening. Edges of the peelable flap are coated with a resealable adhesive, while one side or end of the flap is connected to a portion of the bag's front surface. The pull tab portion of the flap can mate with an opening, such as a slot, at the top end seal of the bag. Once the pull tab is engaged with this opening, the flap is held back out of the way of the opening so that it does not interfere with the consumer's reach for the product, and so it does not fall back towards the bag's surface to inadvertently close the bag when not desired.
