Sealing Cap Break-off Piece for Medical Liquid Disinfection Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing caps for medical liquid containers require complex disinfection procedures for the sealing element, which can be cumbersome and inefficient.
Innovation Solution
A sealing cap design featuring a break-off piece that covers the outer side of the sealing element, allowing for easy access and disinfection by wiping or dabbing, and a slotted sealing element for improved visibility and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the sealing element is covered by a break-off piece to protect it, then the sealing element is protected from contamination, but access to the sealing element for disinfection becomes more difficult
Solution Approach 1:
The break-off piece is designed as a separable component that can be removed to access the sealing element. This segmentation allows the protective cover to be separated from the sealing element, enabling disinfection while maintaining protection during storage and transport.
Solution Approach 2:
The break-off piece is removed in advance before disinfection is required. This preliminary action exposes the sealing element for disinfection while maintaining protection during storage and transport, resolving the contradiction between protection and accessibility.
2Ease of operation
If the sealing element is made accessible for disinfection, then disinfection can be performed easily, but the sealing element becomes more vulnerable to contamination
Solution Approach 1:
The break-off piece is removed in advance before disinfection is required. This preliminary action exposes the sealing element for disinfection while maintaining protection during storage and transport, resolving the contradiction between protection and accessibility.
Solution Approach 2:
The break-off piece is designed as a disposable protective cover that is discarded after use. This allows easy access for disinfection while maintaining protection during storage, as the break-off piece is replaced after a single use.
3Object-affected harmful factors
If a break-off piece is added to cover the sealing element, then protection and accessibility are improved, but the device complexity increases
Solution Approach 1:
The break-off piece is integrated with the cap body as a single molded component. This merging reduces the number of separate parts and assembly steps, minimizing the increase in device complexity while maintaining the protective function.
Solution Approach 2:
The break-off piece serves multiple functions: it protects the sealing element from contamination, provides a structural support for the cap, and acts as a barrier during storage. This multi-functionality reduces the need for additional separate components.

AI summary
A sealing cap for a container for holding a medical liquid includes a cap body and a connection device having a sealing element arranged on the cap body. The sealing element is arranged at the opening and is retained in the cap body in a clamped manner by a, preferably annular, flanged rim. The connection device has a break-off piece, which is firmly connected to the cap body and covers an outer face of the sealing element in the outward direction. The break-off piece is integral with the cap body, is connected to the cap body by a predetermined breaking point where the break-off piece can be detached from the cap body. The sealing element outer face is substantially flat and is accessible for wiping to provide a sealing cap having a sealing element arranged that can be simply and reliably disinfected.
