Paperboard Child-Resistant Container With Tab-Lock Reclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-resistant detergent pod containers are predominantly made of plastic, which is unsustainable, and there is a lack of effective, eco-friendly, child-proof re-closable containers made of paper or cardboard that meet child-resistant standards.
Innovation Solution
A child-proof re-closable container made entirely of paper or cardboard, featuring folding lines and engagement tabs that require complex manipulation to open, ensuring compliance with child-resistant standards and recyclability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic containers are used for detergent pods to ensure child-resistant functionality, then child-proofing is achieved, but environmental sustainability deteriorates due to plastic waste and lack of recyclability
Solution Approach 1:
The patent changes the material parameter from plastic to paper/cardboard while maintaining the child-resistant functional parameters through specialized folding lines and engagement tab structures. This material substitution eliminates plastic waste while preserving the child-proofing functionality through alternative mechanical design elements.
Solution Approach 2:
The container employs a composite structure combining paper or cardboard base material with specific folding line configurations and engagement tab elements. This composite approach integrates the sustainability of recyclable paper materials with the functional requirements of child-resistant packaging through multi-component design.
2Object-affected harmful factors
If paper or cardboard containers are used instead of plastic, then environmental sustainability is improved through recyclability, but achieving child-resistant standards becomes more difficult
Solution Approach 1:
The container is segmented into distinct functional elements: body walls formed by folding lines and engagement tabs positioned at specific locations. This segmentation allows each element to be optimized independently, with engagement tabs specifically designed to prevent child opening while maintaining overall recyclability of the paper/cardboard structure.
Solution Approach 2:
The container utilizes dynamic folding lines that create three-dimensional structure from flat paper or cardboard blanks. These folding lines enable the container to achieve child-resistant features through geometric configuration rather than material properties, allowing the same material to provide both sustainability and safety functionality.
3Reliability
If complex engagement tabs and folding lines are added to paper containers to meet child-resistant standards, then child-proofing is achieved, but manufacturing complexity increases
Solution Approach 1:
The engagement tabs and folding lines are pre-configured in the flat blank design before assembly. This preliminary arrangement of structural elements during the blank design phase simplifies the actual manufacturing process, as the child-resistant features are built into the material layout rather than requiring complex assembly operations.
Solution Approach 2:
The folding lines and engagement tabs are designed to self-assemble through simple folding and engagement actions without requiring complex manufacturing equipment or multi-step processing. The structure serves its own assembly function through the inherent geometry of the folding lines and tab configurations, reducing manufacturing complexity while maintaining child-proofing effectiveness.

AI summary
A container for detergent pods includes a container body and a movable cover, wherein the movable cover has a pair of engagement tabs which, in a closed configuration, engage respective windows to form child-proof engagement formations. The container body and the movable cover are entirely made of paper or cardboard and can be recycled as a paper waste without the need of removing any plastic part.
