Child-Proof Container Coupling for Reusable Standard Packaging Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-proof containers either cannot be reused after the first opening or lack an effective safety mechanism to prevent children from accessing the contents, and they often require modifications to existing packaging plants.
Innovation Solution
A child-proof container design featuring a movable closure system with first and second coupling portions that engage stably in a locking condition, allowing multiple openings and closings, and can be easily opened by adults using a thrust portion or an opening device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a container uses an inviolable opening system that breaks upon first opening, then child safety is improved, but the container cannot be reused and structural integrity is lost
Solution Approach 1:
The container is divided into separable components: a closure system with a first coupling portion and a storage with a second coupling portion. The coupling portions can be disengaged and reengaged multiple times, allowing the container to be opened and closed repeatedly without breaking, thus maintaining structural integrity while providing child safety through the coupling mechanism
Solution Approach 2:
The coupling portions are designed to be dynamically engageable and disengageable. The first coupling portion on the closure system can be inserted into and removed from the second coupling portion on the storage multiple times, transforming the static broken-seal concept into a dynamic reusable mechanism that maintains structural integrity
2Reliability
If a child-proof container uses a complex locking mechanism, then safety is improved, but device complexity increases
Solution Approach 1:
The child-proof mechanism is segmented into simple coupling portions: a first coupling portion on the closure system and a second coupling portion on the storage. These segmented components interact through a simple insertion/removal motion, avoiding complex locking mechanisms while maintaining high child safety through the coupled configuration
Solution Approach 2:
The coupling portions act as intermediaries between the closure system and storage. This intermediary mechanism simplifies the overall system by replacing complex direct locking mechanisms with a mediating coupling interface that provides child safety through its engageable/disengageable nature
3Adaptability or versatility
If a container requires modification of existing packaging plants, then new functionality is achieved, but manufacturing cost and complexity increase
Solution Approach 1:
The closure system with the first coupling portion is designed to be universal and compatible with standard packaging lines. The coupling mechanism can be integrated into existing packaging processes without requiring specialized modification, allowing the same production line to manufacture both regular and child-proof containers
Solution Approach 2:
The coupling portions are designed as simple, replicable components that can be manufactured using existing packaging plant equipment. The first coupling portion on the closure system and the second coupling portion on the storage are straightforward structures that can be produced and assembled on standard production lines without requiring new or modified machinery

AI summary
A child-proof container including a storage, for housing a product, and a closure system configured for defining a closed condition and an open condition of the container. The container includes a first coupling portion carried by the closure system and a second coupling portion carried by the storage and configured for cooperating with the first coupling portion to define a locking condition in which the first and second coupling portions prevent the closure system from passing from the closed condition to the open condition.
