Child-Proof Package Case-Container Coupling for Adult Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-proof packages are inflexible, require specialized blister designs, have complex structures, and are costly to produce, while also being difficult for adults to open easily.
Innovation Solution
A package design featuring a container and case with movable lateral walls, coupled by safety devices with engageable portions and a release mechanism, allowing easy adult opening and preventing child access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a child-proof package uses a closure system with specialized blister designs, then child safety is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The package is divided into separate functional components: a container for products and a case for housing the container. The safety device is segmented into distinct coupling portions (first coupling portion on the case, second coupling portion on the container) that can be independently manufactured and then assembled together, simplifying the overall manufacturing process while maintaining child-proof functionality
Solution Approach 2:
The safety device uses a universal coupling mechanism where the first and second coupling portions can engage with each other through a standardized interface. This allows the same basic coupling design to be used across different product types and package configurations, reducing manufacturing complexity while maintaining reliable child-proof closure
2Reliability
If a child-proof package uses a specialized blister design, then child safety is improved, but production flexibility is reduced
Solution Approach 1:
By separating the container and case into independent components with standardized coupling interfaces, the system gains production flexibility. Different container designs can be paired with the same case and safety device, and vice versa, allowing manufacturers to adapt to various product types without redesigning the entire child-proof mechanism
Solution Approach 2:
The safety device incorporates a dynamic coupling mechanism that allows the container to be securely locked in the case during normal storage, but can be easily opened by adults through a simple action on the coupling portions. This dynamic behavior maintains child safety while allowing controlled access for adults
3Reliability
If a child-proof package uses a complex closure system, then child safety is improved, but ease of opening for adults is reduced
Solution Approach 1:
The coupling portions are designed with different local characteristics: the first coupling portion on the case and the second coupling portion on the container are configured to engage securely to prevent child opening, but include specific local features (such as accessible surfaces or orientations) that allow adults to easily disengage them through simple manual action

AI summary
A child proof package including a container and a case configured for receiving the container; case and container are movable between a closed condition and an open condition. The package includes a safety device having: a first coupling portion carried by the case, a second coupling portion carried by the container; the first and the second coupling portion, in the closed condition of the case, are configured for engaging with each other to define a locking condition of the safety device in which the first and second coupling portion prevent case and container from passing from the closed condition to the open condition. The safety device includes a release portion configured for allowing the disengagement of the first and second coupling portion.
