Snack Food Container with Reclose Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current snack food packaging fails to balance displayability on wire racks and vending machines with protection and reclosability, while also being suitable for cup holders and ergonomic one-hand use.
Innovation Solution
A paperboard container with a three-dimensional square base transitioning to a two-dimensional flat top through geometric folds and creases, featuring a horizontal tear feature for easy access and a reclose mechanism using diagonal score lines for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible pillow bag is used for snack packaging, then it can be easily displayed on wire racks and in vending machines, but it cannot protect the product after opening and does not naturally reclose
Solution Approach 1:
The container is divided into distinct functional zones: a rigid base for structural support and protection, a flexible top seal for displayability, and a reclose mechanism with interlocking features. This segmentation allows each part to fulfill its specific function - the rigid base protects the product while the flexible top enables wire rack display, and the reclose mechanism provides secure closure.
Solution Approach 2:
The patent combines features from different packaging types into a single container: the rigid structure of paperboard containers for protection, the flat top seal of pillow bags for displayability, and an integrated reclose mechanism. This merging creates a hybrid package that exhibits all three desirable characteristics simultaneously.
2Reliability
If a rigid paperboard rectangular container is used, then it protects the product well, but it cannot be displayed on wire racks and does not fit cup holders
Solution Approach 1:
The container transitions from a purely rigid three-dimensional rectangular form to a hybrid structure with a rigid base and a flexible two-dimensional top seal. This dimensional transition allows the container to maintain structural protection while gaining the flat top surface needed for wire rack display and cup holder compatibility.
Solution Approach 2:
Different parts of the container have different mechanical properties: the base is rigid for protection, while the top seal is flexible for display and insertion operations. This local differentiation of material properties allows the container to satisfy multiple contradictory requirements in different spatial zones.
3Reliability
If a cylindrical container with top cap is used, then it protects product and fits cup holders, but it cannot be displayed on wire racks and requires manual reclosing
Solution Approach 1:
Instead of using a traditional cylindrical container with a separate removable cap, the patent inverts the approach by creating a flat top seal that is integrated into the container structure itself. The reclose mechanism uses interlocking features on the container body and flap, eliminating the need for a separate cap while enabling both wire rack display and convenient reclosing.
4Reliability
If a pillow bag with external clip is used to achieve reclosing, then it can close the bag, but it requires external accessories and does not provide natural reclose functionality
Solution Approach 1:
The container incorporates an integrated reclose mechanism where the container body and flap have complementary interlocking features that enable self-closure without external clips. The geometry of the container and flap automatically provides the closing action, making the system self-sufficient and eliminating the need for additional accessories.

AI summary
A snack food container having a square base, side walls substantially consisting of four right triangular panels and two isosceles triangular panels, and a flat, two dimensional end seal. The container is opened by use of a tear feature just below the end seal. The container is of paperboard construction and is resealable by virtue of a score line on each side of the container located below the end seal in combination with a horizontal cut through the container located below one score line. After opening, the container can be resealed by folding the container over the score lines towards the horizontal cut. An edge of the container is then secured in the horizontal cut.
