Attachment Tag With Expandable Elastomer Loop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment tags lack effective mechanisms for securely fastening to products and reclosing flexible containers, such as food bags, while also conveying information, due to limitations in adhesive strength and elasticity.
Innovation Solution
The development of an attachment tag with a tag portion and an expandable elastomer portion, where the elastomer portion is bonded to the tag portion along a specific zone, allowing for secure adhesion and expansion to wrap around products or packages, and a release liner for easy application and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an adhesive layer is used to attach the tag to the product, then the tag can be securely fastened, but the adhesive strength may be insufficient for reclosing flexible containers
Solution Approach 1:
The patent combines two attachment mechanisms: an adhesive layer for initial bonding and an elastomer portion with expandable loop for mechanical securing. This hybrid approach merges the simplicity of adhesive attachment with the reliability of elastic mechanical fastening, enabling both strong initial attachment and reliable reclosing of flexible containers
Solution Approach 2:
The attachment tag uses composite construction with a tag portion made of rigid or semi-rigid material providing structural support and information display, an adhesive layer for bonding, and an elastomer portion providing elastic mechanical fastening. This composite structure integrates multiple material properties to achieve both adhesive strength and securing reliability
2Ease of operation
If the tag structure is simplified for easy application, then ease of operation improves, but the mechanism for securely reclosing packages is limited
Solution Approach 1:
The attachment tag is segmented into distinct functional portions: a tag portion for information display, an adhesive layer for attachment, and an elastomer portion with expandable loop for reclosing. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity in application - the user simply attaches the tag and the elastomer loop provides automatic mechanical securing
3Adaptability or versatility
If the elastomer portion is made highly elastic for wrapping around products, then adaptability improves, but the bond strength between tag portion and elastomer may be compromised
Solution Approach 1:
The elastomer portion is designed with local quality variations - it has high elasticity in the expandable loop region for wrapping adaptability, while the bond zone region is formulated or structured to provide optimal bonding characteristics. This localized differentiation allows the same component to exhibit different properties in different regions, achieving both wrapping capability and bond strength

AI summary
A method for using an attachment tag with a product includes affixing an adhesive layer of the attachment tag to the product. The attachment tag includes an elastomer portion and a tag portion bonded to the elastomer portion along a bond zone, wherein the adhesive layer is disposed on the tag portion. The method also includes expanding the elastomer portion by at least partially separating at least two of a plurality of leg segments of the elastomer portion and securing the expanded elastomer portion around at least a portion of the product.
