Child-Resistant Resealable Container with Biodegradable Lid and Aluminum Bowl
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lightweight packaging is prone to crushing, non-reusable, and lacks an airtight resealable mechanism, making it unsuitable for storing and transporting materials like medication and food, while also failing to provide child-resistant and eco-friendly solutions.
Innovation Solution
A container design featuring a replaceable aluminum foil lower lid with resealing adhesive, a child-resistant upper lid, and a biodegradable/recyclable construction, including a child-proofing ring for secure engagement, allowing for efficient transportation and display while maintaining an airtight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight packaging is used, then weight is reduced, but structural stability deteriorates
Solution Approach 1:
The container combines multiple materials with complementary properties: an aluminum bowl provides structural stability and barrier properties, while a PLA lid offers biodegradability and sufficient mechanical strength. This composite construction achieves both lightweight characteristics and structural stability that neither material could provide alone.
2Weight of moving object
If formed foil packaging is used, then weight is reduced, but reusability deteriorates
Solution Approach 1:
The container employs a thin aluminum foil bowl that is flexible yet durable, combined with a removable PLA lid. The thin-walled construction enables the container to be collapsed flat for compact storage and transport, while the robust joint design between bowl and lid ensures the container can be opened, closed, and reused multiple times without structural degradation.
3Ease of operation
If sealing film is removed, then access to contents is enabled, but airtight seal capability deteriorates
Solution Approach 1:
The container features a dynamic sealing system where the PLA lid can be freely attached and detached from the aluminum bowl. This reversible connection allows users to access contents by removing the lid while maintaining an airtight seal when closed, eliminating the need to permanently破坏 the sealing structure for access.
4Duration of action of stationary object
If flexible pouches are used, then reusability is improved, but space efficiency deteriorates
Solution Approach 1:
The thin-walled aluminum bowl construction allows the container to be collapsed into a substantially flat configuration when empty, reducing its volume for storage and transport to a fraction of its filled state. The flexible yet durable design maintains structural integrity through multiple use cycles while achieving compact form factor for efficient space utilization.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The container is stable, reusable, eco-friendly, and child-resistant, providing an efficient and space-saving solution for storing and transporting materials while ensuring freshness through nitrogen flush capabilities and extended shelf life.
Implementation Method 1
The lower lid includes an adhesive for resealing the lower lid in an open configuration to be in a closed configuration
Implementation Method 2
The ring engages the lip in a friction fit
Implementation Method 3
The ring includes a detent for engaging the lip in the friction fit

AI summary
A container and method include a bowl having an interior for storing a substance, an openable lower lid for accessing the substance when the lower lid is in an open configuration, and an upper lid for retaining the substance within the interior of the bowl and the lower lid. The lower lid in the open configuration is replaceable and resealable using an adhesive to be in a closed configuration, with the substance sealed within the bowl. The bowl, the lower lid, and the upper lid are composed of a biodegradable or recyclable material. A ring is disposed under a lip of the bowl and engageable with the upper lid for establishing a child-resistant engagement between the upper lid and the bowl. An intermediate lid pushes against an engagement surface of the bowl for locking the upper lid and the ring together.
