Rotatable Container System with Lateral Dispensing Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container systems for unit dose detergent compositions, such as 'liquid caps' or 'gel caps', are difficult to open and close securely, posing risks for children and allowing easy access to the contents, as they are not designed with child safety features and can lead to accidental removal or emptying of the contents.
Innovation Solution
A container system comprising a rotatable container and dispensing device with a lateral removal opening, a push-turn closure, and a blocking device that requires adult operation to open, ensuring secure closure and preventing accidental access by children, while allowing easy removal of items via gravity-assisted dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple container with removable lid is used, then ease of operation is improved, but child safety deteriorates as children can easily access contents
Solution Approach 1:
The container employs a dynamic two-position lid mechanism that rotates between closed and open positions. The lid is designed to be held open at approximately 90 degrees to the container body, allowing easy access when intentionally opened, while spring pressure automatically returns it to the closed position, preventing accidental opening by children.
Solution Approach 2:
The container incorporates preliminary anti-action through spring-loaded resistance that opposes unintended lid opening. The spring mechanism creates a force barrier that prevents accidental opening by children while allowing intentional opening by adults who can overcome the spring pressure.
2Object-affected harmful factors
If the container is designed to be securely closed, then child safety is improved, but ease of operation deteriorates as it becomes harder to open and close
Solution Approach 1:
The lid mechanism provides dynamic operation where the lid can be easily pulled open against spring pressure and easily released to close. The spring force assists closing by automatically returning the lid to the closed position after opening, making the closing action simple despite the secure closure design.
Solution Approach 2:
The lid is segmented from the container body as a separate movable component that rotates on a hinge or pivot point. This segmentation allows the lid to be independently manipulated for opening and closing while maintaining a secure sealed connection when closed.
3Ease of operation
If a lateral dispensing opening is added, then ease of operation is improved for item removal, but device complexity increases
Solution Approach 1:
The container is segmented into distinct functional components: the container body, the rotatable lid, and the lateral dispensing opening. This segmentation allows each component to perform its specific function independently while simplifying the overall design and manufacturing process.
Solution Approach 2:
The dispensing opening is positioned laterally on the container body rather than requiring lid removal. This dimensional change from vertical (through lid) to lateral (through container wall) access simplifies the dispensing operation and reduces the number of mechanical components needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The container system provides a safe and easy-to-use solution for storing and dispensing items like detergent caps, ensuring secure closure and child safety by requiring adult operation to open, thus preventing accidental access and maintaining the integrity of the contents.
Implementation Method 1
the container system is advantageously erected or is already in such a position that the dispensing device is at the bottom, and, due to the acting force of gravity, at least one item is in the dispensing device or is pushed into the dispensing device due to the acting force of gravity
