Child-Proof Paperboard Container With Folding Engagement Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-resistant detergent pod containers primarily made of plastic face challenges in achieving sustainability and compliance with child-resistant standards when made of paper or cardboard, as they are difficult to design as re-closable and recyclable.
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 materials are used for detergent pod containers, then child-resistant features and elastic snap-engagement formations can be easily achieved, but sustainability and recyclability are compromised
Solution Approach 1:
The patent changes the material parameter from plastic to paper/cardboard while maintaining the child-resistant function through structural design (folding lines, engagement tabs) rather than material properties. This resolves the contradiction by achieving safety through geometry rather than material selection.
Solution Approach 2:
The patent uses composite paper/cardboard structures with multiple layers and folding configurations to achieve child-resistant features. The composite nature of the folded paper structure provides the necessary mechanical resistance while maintaining sustainability.
2Object-affected harmful factors
If paper or cardboard materials are used for containers, then sustainability and recyclability are improved, but child-resistant features and re-closable functionality become difficult to achieve
Solution Approach 1:
The patent divides the paper/cardboard container into multiple segments through folding lines, creating engagement tabs and flaps that must be manipulated to open. This segmentation provides child-resistant functionality through complex manual manipulation requirements while maintaining the simplicity of paper material.
Solution Approach 2:
The patent introduces dynamic elements through movable flaps, tabs, and folding mechanisms that change the container's configuration during opening. The dynamic manipulation required to navigate the folded paper structure ensures child resistance while allowing controlled adult access.
3Reliability
If complex engagement mechanisms are added to paper containers, then child-resistant standards are met, but manufacturing complexity increases
Solution Approach 1:
The patent segments the container into standard paper components with defined folding lines that can be manufactured using conventional paper forming techniques. The engagement tabs and flaps are created through simple folding and cutting operations rather than complex assembly processes.
Solution Approach 2:
The patent changes the manufacturing approach from assembling complex mechanical components to forming paper structures through folding and bonding. This parameter change in the manufacturing process simplifies production while maintaining the complex functional geometry required for child resistance.

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.
