Child Resistant Pre-roll Case with Segmented Clamshell and Gasket Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a child-resistant case that maintains the structural integrity of pre-rolls, prevents water and moisture from contacting them, contains odors within the storage unit, and prevents children from accessing cannabis.
Innovation Solution
A child-resistant pre-roll case with a clamshell design featuring snap-fit connections, a gasket for air-tight and fluid-resistant seals, and separate compartments for pre-rolls and accessories, ensuring secure closure and easy access for adults while keeping cannabis safe from children.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid storage unit is used to maintain structural integrity of pre-rolls, then pre-rolls are protected from bending and tearing, but the case may not provide adequate child resistance
Solution Approach 1:
The case is divided into a body and a removable lid as separate components. The lid can be completely removed from the body, allowing the pre-rolls to be accessed directly from the body without needing to open or manipulate a lid closure mechanism. This segmentation provides structural protection while enabling simple adult access and difficult child access.
Solution Approach 2:
The removable lid acts as an intermediary element between the environment and the pre-rolls. For adults, the lid can be easily removed to access pre-rolls. For children, the absence of a closure mechanism on the body means the pre-rolls are only accessible when the lid is present and properly positioned, creating a passive child-resistant barrier.
2Reliability
If the case is designed with secure closure mechanisms for child resistance, then child access is prevented, but the case may not allow easy access for adults
Solution Approach 1:
By separating the lid from the body with a removable connection, the case eliminates the need for complex closure mechanisms. Adults can easily access pre-rolls by simply removing or lifting the lid, while children cannot access pre-rolls without the lid being completely removed, providing passive child resistance.
Solution Approach 2:
Instead of designing a closure mechanism that requires effort to open (which would provide child resistance but complicate adult access), the design inverts the approach by having no closure mechanism on the body at all. The lid serves as the only barrier, and its removable nature provides both easy adult access and passive child resistance.
3Ease of manufacture
If the case uses paper or leaf type wraps for pre-rolls, then the pre-rolls are easy to prepare, but they are easily bent, torn, or fall apart
Solution Approach 1:
The case utilizes the flexible paper or leaf type wrap that is already used for pre-roll preparation, but provides additional structural support through the rigid case housing. The wrap maintains its ease of use for preparation while the case prevents bending, tearing, and falling apart during storage and transport.
4Object-generated harmful factors
If the storage unit is designed to be airtight for odor containment, then odors are contained within the unit, but water and moisture may still contact the pre-rolls
Solution Approach 1:
A gasket is installed at the interface between the lid and body to provide both airtight and waterproof sealing. The gasket creates a flexible barrier that prevents both odor escape and water/moisture penetration, protecting the pre-rolls from both types of harmful factors simultaneously.
Solution Approach 2:
The sealing system uses a composite approach combining the rigid case materials with a flexible gasket material. This composite sealing structure provides both airtightness for odor containment and waterproofing for moisture protection.
