Container Stopper Sliding Element for Childproof Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing childproof stoppers for containers with pharmaceutical or chemical products lack effective childproof and user-friendly designs, as they often require complex movements and are not easily tamper-evident, making them difficult for both children and users with large hands to operate.
Innovation Solution
A stopper design featuring a moving element that covers the entire top face, allowing for sliding or rotating movement, providing a large gripping surface for easy operation while appearing non-movable to children, and incorporating a desiccant chamber and tamper-evident members for enhanced security and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the moving element substantially covers the entire top face of the body element in the initial position, then childproof security is improved by obscuring the movable element's functionality from children, but the gripping surface area for user operation is reduced
Solution Approach 1:
The moving element is designed to transition from a static appearance in the initial position (covering the entire top face) to a dynamic extended position that provides a gripping surface. This dynamic transformation allows the same element to serve dual purposes: maintaining childproof security when closed and providing user grip when opened.
Solution Approach 2:
The moving element extends beyond the plane of the top face when moved to the opening position, utilizing the vertical dimension to create a gripping surface while maintaining a flush appearance in the initial position. This dimensional transition resolves the contradiction between covering the top face and providing grip area.
2Ease of operation
If the moving element is designed to be movable from initial position to opening position, then ease of operation is improved for users with large hands, but device complexity increases due to additional moving components
Solution Approach 1:
The moving element is integrated with the body element through a connection mechanism that allows relative movement while maintaining structural unity. This merging approach provides the functionality of a separate moving component while minimizing the increase in overall device complexity.
Solution Approach 2:
The stopper is divided into two functional segments: the body element and the moving element. This segmentation allows the moving element to be operated independently by users with large hands while the rest of the stopper structure remains simple and robust.
3Reliability
If the moving element provides a gripping surface only in the opening position, then childproof characteristics are improved, but ease of operation is worsened requiring precise positioning
Solution Approach 1:
The gripping surface is created in the vertical dimension when the moving element extends beyond the top face plane, rather than requiring a separate lateral extension. This allows children to easily push the element to its extended position without requiring precise lateral positioning.
Solution Approach 2:
The moving element's design allows it to self-position in the opening state once pushed, providing a stable gripping surface without requiring the user to maintain precise positioning. The element remains in the extended position until a closing force is applied.

AI summary
A stopper for closing a dispensing opening of a container which includes a body element having a top face and a bottom face, the bottom face being directed towards the inside of the container; a moving element which is situated at the top face of the body element, wherein the moving element is movable from an initial position in which the moving element does not extend beyond the top face in the plane of the top face, to an opening position in which the moving element is moved to extend at least partly beyond the outer extension of the top face, wherein the moving element provides, a gripping surface for a user to remove the body element from the dispensing opening. The moving element substantially covers the entire top face of the body element in the initial position.
