Deformable Skirt Child-Safe Closure with Integrated Dehydrator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-proof closure devices for containers, especially those with a first-opening indicator and dehydrating functionality, are complex and require separate components, lacking integration of dehydrating means and simplicity in design.
Innovation Solution
A single-piece child-safety closure device with a deformable skirt and integrated dehydrating element, featuring child-safety and tamper-evidence serrations, allowing unscrewing through radial pressure and rotation, and incorporating a dehydrating housing within the stopper for moisture-sensitive products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing child-proof closure devices are equipped with first-opening indicator and dehydrating functionality, then product safety and moisture protection are improved, but device complexity increases and requires separate components
Solution Approach 1:
The patent combines multiple functions (child-proof closure, first-opening indicator, and dehydrating element) into a single integrated closure device. The stopper includes an integrated dehydrating element positioned in its lower part, eliminating the need for separate dehydration means while maintaining all required safety and protection functions.
Solution Approach 2:
The closure device is designed to perform multiple functions simultaneously: the stopper provides child-proof closure through its deformable skirt mechanism, the first-opening indicator collar indicates initial opening through breakable bridges, and the integrated dehydrating element protects moisture-sensitive products, making the device universal for securing, indicating, and protecting.
2Reliability
If existing child-proof closure devices use separate components for dehydrating functionality, then dehydrating effectiveness is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The dehydrating element is integrated directly into the stopper structure as a single-component solution. The stopper is provided with an integrated dehydrating element in its lower part, which can be manufactured as one piece, thereby simplifying production and eliminating separate assembly steps while maintaining effective moisture protection.
3Reliability
If child-proof closure devices require double vertical and rotation movement with internal and external stoppers, then child safety is improved, but ease of operation deteriorates
Solution Approach 1:
The child-proof mechanism is segmented into distinct functional elements: a deformable skirt with diametrically opposed zones for lateral pressure application, child-safety serrations for locking, and breakable bridges for the indicator. This segmentation allows the complex safety function to be achieved through a simpler single-stopper design rather than nested internal and external stoppers.
Solution Approach 2:
The skirt is designed to be deformable under lateral pressure, allowing it to transition from a locked state (preventing rotation) to an unlocked state (allowing rotation and unscrewing). This dynamic deformation property enables the child-proof mechanism to adapt to the applied force while maintaining simplicity in operation.
