RFID Closure Lid for Sterile and Traceable Medicament Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medication containers face challenges in maintaining sterility and traceability during handling and logistics, particularly when dealing with high-volume, high-value, or sensitive active pharmaceutical ingredients, and require improved tamper-proof sealing and efficient tracking.
Innovation Solution
Integration of an RFID transponder into the closure lid of medication containers for traceability, combined with a bayonet fitting mechanism for maintaining sterility and a tamper-evident seal for secure access, allowing for patient-specific dosing and localized labeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medication containers are equipped with traditional sealing caps and tamper-evident seals, then sterility and security are improved, but traceability and logistics efficiency deteriorate
Solution Approach 1:
The patent combines multiple functions into the closure lid: the RFID transponder for traceability, the sealing membrane for sterility, and the tamper-evident seal for security are all integrated into a single closure lid assembly. This merging eliminates the need for separate components and enables simultaneous achievement of traceability, sterility, and security.
Solution Approach 2:
The closure lid serves multiple functions: it provides sealing (sterility), tamper evidence (security), and RFID tracking (traceability). The base body of the closure lid acts as a universal platform that accommodates all these functions, allowing a single component to address multiple requirements that previously needed separate solutions.
2Productivity
If automated filling systems process containers in high volumes through nesting, then productivity is improved, but the risk of unintentional losses and contamination increases
Solution Approach 1:
The closure lid with integrated sealing membrane and tamper-evident seal is prepared in advance before filling. The pre-assembly of the closure lid on the container creates a protected environment prior to filling, reducing exposure to contamination risks during high-volume automated processing.
Solution Approach 2:
The RFID transponder provides real-time tracking and identification of individual containers throughout the automated filling process. This enables the system to monitor each container's status, location, and handling, providing feedback that prevents unintentional losses and ensures proper processing even at high speeds.
3Loss of information
If individual container tracking is implemented throughout the logistics chain, then traceability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The RFID transponder is integrated directly into the base body of the closure lid, combining the tracking function with the existing sealing structure. This integration eliminates the need for separate tracking devices and reduces overall system complexity while maintaining individual container traceability throughout the logistics chain.
4Reliability
If tamper-evident seals and sealing membranes are used, then security and sterility are improved, but ease of operation and access deteriorate
Solution Approach 1:
The closure lid system incorporates dynamic elements: the tamper-evident seal can be broken to indicate opening, and the sealing membrane can be pierced for medication access. These dynamic features allow the system to transition from a sealed state to an accessed state while maintaining evidence of the transition, balancing security with usability.

AI summary
A closure lid (12) for a medication container (1, 1'), the interior (4) of which is accessible via a container opening (6, 6') designed in the manner of a bottle neck, is intended to enable the most complete possible tracking of even individual containers (1, 1') in order to improve the logistics chain. For this purpose, an RFID transponder (15) is integrated into a base body (14) of the closure lid (12) according to the invention.
