Bag Closure Clip with Integrated Display Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure clips for flexible packaging have limited surface area for information display, leading to high costs and poor humidity resistance, and are prone to unpredictable separation due to material density variations in plastic links, causing production delays and increased costs.
Innovation Solution
A closure clip design featuring a planar body with a symmetry axis, shoulders, and flexible tabs that allow bag insertion and removal, along with a displaying label, made from materials like polyethylene or polypropylene, which reduces material usage and allows for clear information printing, while the flexible tabs and optimized geometry enhance separation reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the surface area of closure clips is increased to display more information, then the quantity of information that may be printed and displayed is improved, but more materials are used which is associated with greater costs
Solution Approach 1:
The closure clip transitions from a conventional two-dimensional flat shape to a three-dimensional geometric configuration with a prismatic body, curved front surface, and integrated shoulder structures. This dimensional transformation increases the available surface area for information display without proportionally increasing material consumption, as the geometry optimizes surface-to-volume ratio.
Solution Approach 2:
The invention modifies key geometric parameters including the curvature radius of the front surface (R1), the dimensions and positioning of shoulders (height H1, width W1), and the overall body proportions. These parameter optimizations allow maximum information display area while controlling material usage within acceptable cost ranges.
2Loss of information
If a paper label is stuck to a closure clip to print information, then the required information can be displayed, but the price increases, the paper label is not humidity-resistant, and the adherence is poor
Solution Approach 1:
The information display function is merged directly into the closure clip body itself. The curved front surface and shoulder areas form an integrated display region that is inherently part of the clip structure, eliminating the need for separate paper labels. This integration ensures the display surface inherits the clip's material properties including humidity resistance and structural durability.
Solution Approach 2:
The invention replaces expensive, non-durable paper labels with the closure clip's own permanent surface. The clip body, made from durable plastic material, serves as the lasting display medium, eliminating recurring costs associated with label replacement due to moisture damage or poor adhesion.
3Productivity
If plastic links are used to attach closure clips in rolls, then the clips can be supplied in rolls, but small variations in material density make the separation process unpredictable causing delays and higher costs
Solution Approach 1:
The closure clip is designed with distinct geometric segmentation including protruding shoulders and curved front surfaces that create natural separation zones between adjacent clips in a roll. These geometric features ensure consistent break points during separation, making the process predictable and reliable regardless of minor material density variations.

AI summary
A closure clip for maintaining a bag closed is provided. The clip includes a planar body having a symmetry axis. The planar body defines a rear portion having a frontward border, a rearward border and lateral borders, a pair of shoulders, each extending outwardly and along one of the lateral borders and a pair of tabs projecting from the frontward border frontwardly and towards the symmetry axis, the tabs having free front extremities curving towards each other, the tabs and a portion of the frontward border delimiting an opening for receiving a portion of the bag. The planar body has a perimeter comprising an inflection point provided on each side of the symmetry axis, at a transition between one of the shoulders and a corresponding one of the tabs. The clip can include a displaying label projecting rearwardly from the rearward border. A strip of closure clips is also provided.
