Storage Bag Closure Profile with Gripping Ridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plastic storage bags with zipper-like closure mechanisms are difficult to seal and unseal, especially when wet or slippery, and have slick surfaces that are hard to grasp, making it challenging for users to perform these operations effectively.
Innovation Solution
The storage bag features a closure profile with gripping ridges and texture along its edges, providing a secure grip and tactile feedback to facilitate easy sealing and unsealing, even when wet or slippery, by incorporating a plurality of gripping ridges and raised features that enhance grippability and tactile sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the storage bag uses a smooth plastic surface for the closure mechanism, then the sealing process is simple and the bag is easy to manufacture, but the user cannot get a secure grip on the bag when it is wet or slippery
Solution Approach 1:
The closure profile incorporates gripping ridges and textured surfaces only in the specific regions where user contact is needed, while maintaining smooth surfaces in other areas. This localized texturing provides enhanced grip security exactly where required without unnecessarily complicating the entire closure structure.
Solution Approach 2:
The closure profile is divided into multiple functional segments including gripping ridges, textured areas, and smooth sections. Each segment serves a specific purpose: the ridges provide finger placement guides, the textured areas enhance grip, and the smooth areas maintain simplicity. This segmentation resolves the contradiction by distributing complexity only where beneficial.
2Ease of operation
If the storage bag closure mechanism has no texture or ridges, then the manufacturing process is simpler and the structure is less complex, but the user experiences difficulty in sealing and unsealing the bag
Solution Approach 1:
The gripping ridges and textured surfaces are integrated directly into the closure profile during the molding process, combining the sealing function and the gripping enhancement function into a single unified structure. This merging allows the closure profile to provide both sealing capability and improved user interaction without requiring separate manufacturing steps or additional components.
3Ease of operation
If the storage bag has a slick surface, then the bag is easier to clean and maintains a smooth appearance, but the user cannot grasp the bag securely to perform sealing or unsealing operations
Solution Approach 1:
The surface texture is applied locally only to the gripping zones of the closure profile, while the rest of the bag surface remains smooth. This localized texturing provides enhanced graspability where needed without compromising the overall smooth appearance and cleanability of the bag.

AI summary
A storage bag has first and second closure profiles adjacent to an opening of the bag. The first and second closure profiles are each provided with a closure member that extends along the length of the respective closure profile, with the closure member of the first closure profile being configured to engage with the closure member of the second closure profile to form a seal for the opening of the bag. The first closure profile further includes (a) a plurality of gripping ridges that extends from the closure member to the top edge of the first closure profile, and (b) a texture that extends in an area between the closure member and the top edge of the first closure profile, with the texture extending continuously (i) in the area between the closure member and the top edge of the first closure profile, and (ii) between each gripping ridge of the plurality of gripping ridges.
