Flip-Top Closure With Elastic Web For Child Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-resistant closures for bottles and containers often fail to provide a secure and user-friendly mechanism for opening and closing, as they can be difficult for adults to operate while maintaining resistance to children.
Innovation Solution
A child-resistant closure system featuring a flip-top cap with an elastic web and upstanding cap-retainer latches that mate with retention lugs on the cap, allowing the cap to be easily opened by deforming the elastic web, ensuring secure closure and easy access for adults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional closure mechanism is used, then the structure is simple, but it cannot effectively prevent children from opening while remaining easy for adults to operate
Solution Approach 1:
The closure mechanism changes the operational parameter from simple rotational movement to a two-step action requiring specific force application. The elastic web requires compression beyond a threshold to disengage latches, transforming the opening operation from easy rotation to a controlled sequence that distinguishes adult from child capability.
Solution Approach 2:
The closure system incorporates dynamic elements including the elastic web that deforms under force and the latches that move between engaged and disengaged states. The flip-top cap transitions from a static cover to a dynamically controlled component that responds to applied force through the hinge mechanism, creating adaptive resistance based on user action.
2Reliability
If a secure locking mechanism is implemented, then child resistance is improved, but the complexity of the closure system increases
Solution Approach 1:
The closure system is segmented into distinct functional components: the elastic web for force absorption and transmission, multiple latches for secure engagement, a hinge for controlled movement, and retention lugs for latch attachment. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability.
Solution Approach 2:
The latch mechanisms are nested within the body structure, with retention lugs integrated into the flip-top cap and latches positioned within recesses in the body. The elastic web is contained within the body housing, creating a compact nested arrangement that reduces overall complexity while maintaining security functions.

Function Achieved in This Case
The system effectively prevents accidental opening by children while allowing adults to easily access the contents by deforming the elastic web, providing a secure and user-friendly mechanism for opening and closing.
Implementation Method 1
the body includes an elastic web and an upstanding cap-retainer latch coupled to the elastic web for movement therewith during deformation of the elastic web
