Child-Resistant Beverage Lid With Cloverleaf Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing need for child-resistant packaging for cannabis-infused beverages and other potentially harmful beverages due to increased usage and regulatory requirements, as existing packaging does not adequately secure the contents from children.
Innovation Solution
A child-resistant lid design that can be snap-fit onto standard beverage cans, featuring a cloverleaf-shaped cover and a tamper-evident strip, which secures the lid in place and requires a specific alignment to access the pull-tab, ensuring the contents remain sealed until intended for consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a child-resistant lid is designed with a complex locking mechanism, then child resistance is improved, but device complexity increases
Solution Approach 1:
The lid is divided into separate functional components: a base lid, a removable cover, and a locking mechanism with distinct elements (protrusion and recess). This segmentation allows each component to perform its specific function while simplifying the overall design and manufacturing process.
Solution Approach 2:
The locking mechanism employs asymmetric geometry where the protrusion on the base lid must align with a specific recess on the cover. This asymmetric design provides secure locking while maintaining simplicity, as the misalignment naturally prevents opening without requiring complex interlocking structures.
2Reliability
If a tamper-evident strip is added to the lid, then security is improved, but device complexity increases
Solution Approach 1:
The tamper-evident function is extracted as a separate strip component that can be independently applied to the lid. This strip includes a breakable seal or indicator that remains intact during normal storage but breaks or changes when the lid is opened, providing security without integrating complex mechanisms into the lid structure itself.
3Reliability
If the lid requires specific alignment to access the pull-tab, then child resistance is improved, but ease of operation decreases
Solution Approach 1:
The lid design incorporates preliminary alignment features that automatically position the pull-tab in an accessible location when the lid is correctly assembled on the can. The protrusion and recess alignment ensures that once the lid is secured, the pull-tab is naturally positioned for easy access, eliminating the need for complex manual alignment operations.

AI summary
Disclosed is a child-resistant beverage lid with a tabbed cover that is attached to the base of the lid via a hinge. The lid may be removed by pulling up on the tab with sufficient force that it lifts the cover up and the lid up and off of a can.
