Child Resistant Double Seam Lid Adapter Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional can lids are difficult for children to reopen once opened, posing a safety risk, and existing child-resistant solutions do not effectively address the need for easy adult access while maintaining security.
Innovation Solution
A child-resistant double seam container lid system comprising a two-piece or three-piece design with an adapter ring, rotational alignment indicators, and optional features like a liquid-tight seal and measuring cup, which securely affixes to the double seam of conventional containers, making it difficult for children to open but easily removable by adults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional can lid is used, then it is easy to open, but children can easily open it posing a safety risk
Solution Approach 1:
The lid is divided into multiple components: a first piece lid portion and a second piece adapter ring locking member. The adapter ring secures to the container while the lid portion can be removed only when properly aligned, creating a segmented system that prevents child access while allowing adult operation.
Solution Approach 2:
The adapter ring acts as an intermediary component between the container and the lid portion. It provides the locking mechanism that children cannot operate but adults can, mediating the interaction between the user and the container to ensure safety.
2Object-affected harmful factors
If a child-resistant locking mechanism is added, then child safety is improved, but the device complexity increases
Solution Approach 1:
By segmenting the lid into a lid portion and an adapter ring locking member, the complex locking function is distributed across separate components. Each component has a simpler individual structure, but together they provide robust child-resistant functionality.
Solution Approach 2:
The adapter ring serves multiple functions: it secures to the container double seam, provides the locking mechanism, and interfaces with the lid portion. This multi-functionality reduces the need for additional separate components, managing overall device complexity.
3Object-affected harmful factors
If a two-piece or three-piece design with adapter ring is used, then child resistance is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The lid system is manufactured as separate components (lid portion and adapter ring locking member) that can be produced using standard manufacturing processes for each piece, then assembled. This segmentation allows each component to be optimized for its specific manufacturing requirements.
Solution Approach 2:
The adapter ring combines several functional elements into a single component that interfaces with both the container and the lid portion. This merging reduces the total number of parts compared to alternative designs while maintaining child-resistant functionality.
