Two-Part Cardboard Folding Box with Child-Resistant Reclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardboard packaging solutions are either difficult for adults to open or lack child-resistant features, and plastic packaging poses environmental disposal issues.
Innovation Solution
A folding box with a locking mechanism that requires two-handed operation and multiple steps to open, featuring reinforced walls and additional locking tabs to ensure child-resistance and resealability, made from cardboard or paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cardboard packaging is made simpler to open, then ease of operation improves, but child-resistant features are compromised
Solution Approach 1:
The packaging is divided into two separate components: an outer sleeve and an inner insert. The locking mechanism is segmented into multiple independent locking tabs (first and second locking tabs) that engage with corresponding slots. This segmentation allows the packaging to maintain strong child-resistant features while enabling easy opening through a simple pulling motion that simultaneously disengages both locking mechanisms.
Solution Approach 2:
The inner insert acts as an intermediary element between the user and the outer sleeve. The insert includes locking tabs that engage with the sleeve, creating a controlled interaction mechanism. This intermediary structure allows adults to easily open the packaging by pulling the insert, while the engineered locking engagement prevents children from opening it.
2Reliability
If plastic packaging is used to achieve secure closure, then child-resistant feature improves, but environmental harm worsens
Solution Approach 1:
The material parameter is changed from plastic to cardboard/paper. The invention achieves the same closure security function using cardboard material with engineered locking tabs and slots. This parameter change eliminates the environmental harm associated with plastic disposal while maintaining the reliability of the child-resistant closure through mechanical locking design.
3Reliability
If multiple locking mechanisms are added to enhance child-resistance, then reliability improves, but device complexity increases
Solution Approach 1:
Multiple locking functions are merged into a simple pulling action. The first and second locking tabs on the insert engage with corresponding slots in the sleeve, creating multiple locking points. However, opening the packaging requires only a single pulling motion that simultaneously disengages both locks, maintaining simplicity despite enhanced security.
Solution Approach 2:
The inner insert serves multiple functions: it contains the product, provides structural support, and houses the locking mechanism. The locking tabs on the insert engage with the sleeve to provide child-resistant closure, while the same insert structure enables easy opening by the user. This multi-functionality reduces overall device complexity.
