Tamper Evident Label with Frangible Tab and Deadened Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security labels are difficult to open in medical or healthcare settings and lack clear visual indicators of tampering, making them inconvenient and unreliable.
Innovation Solution
A tamper evident label comprising a base ply with internal cuts and a top ply with tab cuts, laminated together, which provides a visual indication of tampering when the tab is removed, and optionally includes an inlay element that is disabled upon removal, ensuring the label cannot be resealed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security labels are used to ensure container security, then tamper protection is improved, but ease of operation deteriorates (difficult to open)
Solution Approach 1:
The label is divided into a first portion (base ply with adhesive) and a second portion (top ply with tab), connected by a frangible connection. This segmentation allows the label to be easily separated into functional components: the base provides secure attachment while the tab provides easy manual removal, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The label transitions from a static sealed state to a dynamic open state through the frangible connection. The frangible tab is designed to break or separate cleanly under minimal force, enabling the label to adapt from providing strong tamper protection to allowing easy opening when authorized, thus resolving the contradiction between reliability and ease of operation.
2Reliability
If existing security labels are used, then tamper protection is improved, but visual detection of tampering deteriorates (difficult to determine if fractured)
Solution Approach 1:
The label incorporates visual indicators such as color changes or distinct patterns in the frangible connection region. When the tab is broken or separated, these visual elements change appearance or reveal tamper evidence, making it immediately obvious whether the label has been compromised. This resolves the contradiction by providing both tamper protection and clear visual detection capability.
3Ease of operation
If tab cuts are added to enable easy removal, then ease of operation is improved, but manufacturing precision requirements worsen (alignment of internal cuts and tab cuts)
Solution Approach 1:
The internal cuts and tab cuts are pre-formed during manufacturing with predetermined alignment. This preliminary action ensures that when the label is applied and later removed, the frangible connection separates cleanly along the pre-established cut lines. The alignment is built into the manufacturing process itself, resolving the contradiction between ease of removal and manufacturing precision requirements.

AI summary
A tamper evident label is provided. The tamper evident label broadly includes a base ply of pressure-sensitive material and a top ply of pressure-sensitive material. The base ply and the top ply are laminated together to form the tamper evident label The base ply includes a first portion and a second portion. The second portion of the base ply includes internal cuts and deadened adhesive. The top ply includes a tab portion defined by tab cuts. The tab portion of the top ply and the region between the internal cuts of the base ply are configured to be removed from the tamper evident label to create visual evidence of tampering. Further, a method of constructing a tamper evident label and a method of using a tamper evident label are provided.
