Storage Bag Closure Profile With Colored Lips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plastic storage bags with zipper-like closure mechanisms are difficult to seal and unseal due to slick surfaces, and distinguishing between different bags is challenging, especially in crowded storage environments.
Innovation Solution
The storage bag features a unique closure profile design with differently colored or shaded lips, offset lip configurations, and textured surfaces to facilitate easy grasping and unsealing, while the colored lips provide visual differentiation between bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the closure mechanism uses slick plastic surfaces, then the bag is easy to manufacture and has a smooth appearance, but it becomes difficult to grasp and unseal
Solution Approach 1:
The patent applies a textured coating specifically to the lip regions of the closure mechanism, while leaving other areas smooth. This localized texturing provides enhanced grip exactly where fingers need to grasp the bag for sealing and unsealing, without affecting the overall smooth appearance or manufacturing simplicity of the plastic bag.
2Productivity
If multiple storage bags are stored together, then storage efficiency increases, but it becomes difficult to distinguish between individual bags
Solution Approach 1:
The patent incorporates colored pigments into the lip regions of the closure mechanism. These color-coded lips allow users to quickly identify and distinguish between different storage bags even when multiple bags are stacked or stored together, improving bag identification without affecting storage efficiency.
3Reliability
If the closure mechanism requires precise finger positioning for proper sealing, then sealing reliability improves, but user awareness and proper technique become necessary
Solution Approach 1:
The textured lip regions act as self-guiding features that naturally direct finger placement during the sealing process. The tactile feedback from the textured surfaces helps users automatically position their fingers correctly on the closure mechanism, eliminating the need to learn or remember specific techniques while maintaining reliable sealing engagement.

AI summary
A storage bag has a first closure profile attached to a first side surface, with the first closure profile forming a lip between an interlocking member and an edge of the first closure profile. The bag also includes a second closure profile attached to the second side surface, with the second closure profile forming a lip between an interlocking member and an edge of the second closure profile. The lips of the first and second closure profiles are visually distinct colors or different shades of a color in order to aid the user in locating the lips.
