Childproof Container Closure System With Guide Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing childproof containers are either complex to manufacture, require modifications to standard packaging equipment, or are not easily openable by adults, lacking a simple, compact, and economically viable solution that ensures safety and ease of use.
Innovation Solution
A childproof container design featuring a closure system with a safety device comprising coupling portions that engage to prevent opening by children, while allowing easy access by adults, using a compact and lightweight structure made from sheet material, including a movable closure system and a guide body to facilitate opening with a specific opening device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a childproof closure system with hooks and slots is used, then child safety is improved, but device complexity increases
Solution Approach 1:
The closure system is divided into distinct functional components: a closure element with a slot, a pusher element with a tab, and a sealing element with a protrusion. This segmentation allows each component to perform its specific function while maintaining overall system simplicity and ease of manufacturing.
Solution Approach 2:
The pusher element is positioned between the closure element and the sealing element, creating a nested arrangement where the pusher's tab fits into the slot of the closure element, and the sealing element's protrusion engages with the closure element. This nesting reduces the overall complexity by integrating multiple functions into a compact structure.
2Reliability
If a complex childproof container structure is implemented, then child safety is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The container is divided into simple, manufacturable components (closure element, pusher element, sealing element) that can be produced using standard packaging equipment. Each element is designed with simple geometries (slots, tabs, protrusions) that are easy to form and assemble, reducing manufacturing complexity and cost.
Solution Approach 2:
The closure element serves multiple functions: it provides the structural closure, contains the slot for the pusher tab, and engages with the sealing element's protrusion. This multi-functionality reduces the number of separate components needed, simplifying manufacturing while maintaining child safety.
3Stability of the object's composition
If a stable locking structure is used, then structural integrity is improved, but ease of opening by adults deteriorates
Solution Approach 1:
The pusher element acts as an intermediary between the adult user and the locking mechanism. The tab on the pusher element inserts into the slot on the closure element, allowing the adult to apply force through the tab to disengage the sealing element's protrusion from the closure element, thereby opening the container easily while maintaining stable locking during normal use.

AI summary
The present invention relates to a childproof container (1) comprising a store (2) and a closure system (7) and defining a compartment (8). The container comprises a safety device (11) with a first coupling portion (12) and a second coupling portion (13) configured to engage each other stably in an internal volume of the container (1) in a closing condition of the closure system (7) to define a locking condition wherein they prevent the closure system (7) from switching from the closing to the opening condition. The closure system (7) comprises an unlocking portion (18) configured to define a through access (19) that allows, in the locking condition of the safety device (11), the insertion of an opening device (20) into the internal volume of the container (1) that allows the disengagement between the first and second coupling portions (12, 13). The container comprises a guide body (24) carried by at least one between the second coupling portion (13) and the closure system (7). The guide body (24), in the closing condition of the closure system (7), is placed in the internal volume of the container (1) and is configured to guide the opening device (20) towards the safety device (11).
