Child Resistant Closure Guard Deflection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-resistant closure mechanisms for containers have a large profile, which is undesirable for certain applications, and combining seal and closure mechanisms can compromise their effectiveness.
Innovation Solution
A container design with a child-resistant closure that includes a resilient guard with a small profile, independent of the seal mechanism, allowing for easy opening by applying inward radial pressure to deflect the guard and expose the underside of the cap's front tab, while maintaining a moisture-tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the profile of the guard is reduced to allow for more convenient storage, then the outer-most surface of the guard is about 2 mm to 4 mm from the container body, but the functionality of the child resistant closure may be adversely affected
Solution Approach 1:
The patent applies parameter changes by modifying the geometric dimensions of the guard while maintaining its protective function. The guard's outer-most surface is positioned at about 2 mm to 4 mm from the container body, representing a specific parameter optimization that reduces profile while preserving child resistant closure functionality through carefully controlled dimensional relationships between guard components
2Ease of manufacture
If the seal and closure mechanism are combined in a single structure, then the manufacturing is simplified, but the integrity of both the seal and closure mechanism may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the sealing and closure functions into separate, independent structures. The seal is formed between the container body and cap, while the closure mechanism operates independently through the guard structure. This segmentation allows each component to be optimized for its specific function without compromising the other, maintaining both manufacturing simplicity and functional integrity
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 design provides effective child-resistant closure functionality with a small profile guard and independent seal and closure mechanisms, ensuring the container remains secure without compromising the seal's integrity.
Implementation Method 1
A child resistant closure configured to impede opening of the container when in an engaged position. The child resistant closure includes a resilient guard configured to deflect inward radially when inward radial pressure is applied to it

AI summary
Disclosed are methods for opening containers having child resistant closures. The methods include applying inward radial pressure on a resilient guard of a container to deflect the guard inwardly, followed by applying upward pressure to an exposed front tab of a cap of the container to open the cap.
