Security Label for Medicament Packaging with Peel-Off Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security labels for blister packs do not adequately meet child safety standards, as they can be easily opened by children, leading to unauthorized access and accidental exposure to medications.
Innovation Solution
A security label with a dual-layer design featuring a security layer glued to the aluminum foil, incorporating pull-off elements with reduced adhesive force and strategically placed inhibition points, cuts, and T-shaped opening cuts to prevent accidental opening, while allowing easy access for patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security label with a peel-off element is used to protect against unauthorized opening, then child safety is improved, but the label can still be easily opened by children following the outline shape
Solution Approach 1:
The security label is divided into multiple functional layers: a base layer adhering to the packaging, a security layer with reduced adhesive force, and a peel-off element. This segmentation creates distinct zones with different adhesive characteristics, making it difficult for children to remove the entire label while allowing controlled access for patients.
Solution Approach 2:
Different regions of the security label have different adhesive properties. The base layer has strong adhesive force for secure attachment, while the security layer has reduced adhesive force to enable controlled peeling. This local differentiation of adhesive quality resolves the contradiction between secure protection and controlled access.
2Ease of operation
If the adhesive force of the security layer is reduced to allow easy removal, then ease of operation is improved, but the protection against accidental opening is weakened
Solution Approach 1:
The adhesive structure is segmented into multiple layers with different adhesive forces. The base layer maintains strong adhesion for secure attachment, while the security layer has reduced adhesion for easy removal. This segmentation allows each layer to fulfill its specific function without compromising the other.
Solution Approach 2:
The security label exhibits local quality differentiation in adhesive force distribution. Regions with reduced adhesive force are positioned where controlled peeling occurs, while regions with strong adhesive force maintain secure attachment. This spatial differentiation resolves the contradiction between ease of removal and protection against accidental opening.
3Reliability
If a dual-layer design with security layer and base is used, then protection against accidental opening is improved, but device complexity increases
Solution Approach 1:
The security label merges multiple functions into a single integrated structure: the base layer provides secure attachment, the security layer provides controlled peeling, and the peel-off element enables patient access. This merging of functions reduces overall system complexity while maintaining protection against accidental opening.
Solution Approach 2:
The security label structure serves multiple functions simultaneously: it protects against accidental opening, enables controlled patient access, and maintains secure attachment to the packaging. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The label effectively prevents unauthorized access by children due to increased resistance and complexity in the removal process, while allowing patients to easily access medications with minimal effort.
Implementation Method 1
An adhesive layer (12) is attached to the respective underside of the security layer (10) and the base (11) so that the base (11) can be glued to an individual packaging (13) and the security layer (10) to the base (11)
Implementation Method 2
a silicone-containing lacquer to reduce the adhesive force, since this sufficiently weakens the adhesive force without completely eliminating the adhesive effect

AI summary
The invention relates to a security label for protecting medicaments contained in an individual packaging, comprising a base layer (11, 111, 211) that can be stuck to the individual packaging (10, 110), at least one opening cut (26, 226) being formed in the base layer (11, 111, 211), in the region of the medicament (16) to be inserted. A security layer (10, 110) is stuck to the base layer (11, 111, 211), and removable elements (19) are formed in the security layer (10, 11) in the region of the medicaments (16) to be inserted, in such a way that cuts (18) are made in the security layer (10, 110) on the edge of the removable elements (19), said cuts (18) following a virtual cut strip. Furthermore, a means for reducing or eliminating the adhesive force of the adhesive of the security layer (10, 110) is applied to the base layer (11, 111, 211) in the region of the removable elements (19).
