Pediatric Dosing Dispenser Flip-Top Lock for Child Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing dispensers lack effective child-resistant mechanisms, allowing children to easily access and open containers, posing a safety risk.
Innovation Solution
A dosing dispenser with a child-resistant lock mechanism that includes a flip-top cap and a child-resistant lock featuring a lock tab, tab retainer, actuator pad, and cap-opening lip, requiring a two-handed operation to open, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple flip-top cap is used, then ease of operation is improved, but child resistance deteriorates
Solution Approach 1:
The cap opening mechanism is segmented into multiple independent components: a flip-top cap for initial opening, a child-resistant lock with lock tab and tab retainer for security, and an actuator pad for unlocking. Each component performs a specific function in the opening sequence, requiring coordinated multi-step operation that adults can perform but children cannot
Solution Approach 2:
The child-resistant lock is pre-configured in a locked state during manufacturing, with the lock tab initially engaged with the tab retainer. The actuator pad is pre-positioned to require deliberate pressing action to disengage the lock. This preliminary locked configuration ensures child resistance is inherent from the start without requiring additional locking steps by the user
2Object-affected harmful factors
If a child-resistant lock mechanism is added, then child resistance is improved, but device complexity increases
Solution Approach 1:
The child-resistant lock mechanism is merged with the existing flip-top cap structure rather than being a separate assembly. The lock tab is integrated into the cap wall, the tab retainer is formed as part of the cap body, and the actuator pad is positioned on the cap surface. This merging reduces overall device complexity while maintaining child resistance functionality
Solution Approach 2:
The flip-top cap serves multiple functions: it acts as the primary closure element, incorporates the child-resistant lock mechanism, provides the actuator pad interface for unlocking, and maintains the discharge aperture sealing. This multi-functionality reduces the need for separate components, thereby reducing device complexity while achieving child resistance

AI summary
A package that is configured to store and dispense fluids. The package includes a container and a dosing dispenser for closing an opening to the container. The dosing dispenser includes a body portion having a discharge aperture. Discharge aperture may be closed and opened using a flip-top cap of the dosing dispenser. A container for a package that is configured to store and dispense fluids is also provided.
