Pharmaceutical Dispensing Device Childproof Protective Covering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for pharmaceutical media lack effective mechanisms to prevent accidental actuation, particularly by children, which can lead to unintended dispensing of the medium.
Innovation Solution
A removable protective covering is integrated into the dispensing device, coupled to the housing via a secure coupling device that requires specific functional portions to uncouple, making it difficult for children to access and actuate the device without adult assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cap is provided over the dispensing opening to prevent undesired dispensing, then safety against accidental dispensing is improved, but the device complexity increases and the dispensing opening is covered along with the actuating handle
Solution Approach 1:
The protective covering is divided into two separate components: a first protective covering for the actuating handle and a second protective covering for the dispensing opening. This segmentation allows each covering to be independently designed and removed, simplifying the overall configuration while maintaining safety for both components.
2Reliability
If the protective covering covers both the actuating handle and dispensing opening, then comprehensive protection is improved, but the protective covering becomes larger and more complex in configuration
Solution Approach 1:
The protective covering is segmented into separate first and second coverings that can be independently removed. The first protective covering is removed to enable actuating handle movement, and the second protective covering is removed to enable medium dispensing. This segmentation reduces the size and complexity of each individual covering while maintaining comprehensive protection.
3Reliability
If a secure coupling device is used to attach the protective covering to the housing, then prevention of undesired actuation by children is improved, but the ease of operation for adults decreases
Solution Approach 1:
The coupling device incorporates different local qualities: a secure coupling mechanism that requires specific actions to detach, ensuring childproof protection, while simultaneously providing accessible detachment paths for adults through the defined removal sequence. The first and second protective coverings have different coupling characteristics that match their respective safety requirements.
Solution Approach 2:
The system requires preliminary actions in a specific sequence: first removing the protective covering from the actuating handle, then removing the protective covering from the dispensing opening. This preliminary action sequence ensures that adults follow the correct procedure while preventing children from accessing the device.

AI summary
The invention relates to a dispensing device for a preferably liquid or pulverulent medium, preferably for a pharmaceutical medium, having a housing, a media store for accommodating the medium, a dispensing opening for discharging the medium, and an actuating handle which, by relative movement in relation to the housing, can bring about a dispensing operation. The housing has a removable protective covering by which the actuating handle or the dispensing opening is covered in a storage state, wherein, in the storage state, the protective covering is connected to the housing by a coupling device, and the coupling device can be uncoupled by engagement of at least one functional portion of the dispensing device, it being possible for the functional portion to be moved in relation to the housing and the protective covering.
