Packaging Container Outlet Rim Design for Liquid Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple space containers for packaging perishable food products face issues where liquid exuded from the product can become blocked at the outlet opening, preventing effective liquid discharge and separation from the product.
Innovation Solution
The container design incorporates a rolled rim configuration around the outlet opening, which prevents liquid from blocking the opening while maintaining the original dimensions, ensuring reliable liquid discharge and separation from the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid is discharged from the product space to the receiving space through an outlet opening, then liquid separation from the product is achieved, but liquid can become blocked at the outlet opening preventing effective discharge
Solution Approach 1:
The outlet opening is given a rounded or curved configuration instead of a sharp corner design. This curvature prevents liquid from pooling and blocking the opening, as the rounded shape allows liquid to flow more smoothly through the outlet without accumulating at corners or edges, thereby maintaining reliable discharge functionality.
Solution Approach 2:
The partition means are configured to have different properties at different locations: the outlet opening area has a specific rounded geometry to prevent blocking, while other portions of the partition means maintain their barrier function. This local differentiation allows the outlet region to have optimized liquid flow characteristics while the rest of the partition continues to separate product and receiving space effectively.
2Productivity
If the outlet opening diameter is increased to prevent liquid blocking, then liquid flow is improved, but the separation effectiveness between product and liquid is reduced
Solution Approach 1:
The partition means are configured to have different properties at different locations: the outlet opening area has a specific rounded geometry to prevent blocking, while other portions of the partition means maintain their barrier function. This local differentiation allows the outlet region to have optimized liquid flow characteristics while the rest of the partition continues to separate product and receiving space effectively.
Solution Approach 2:
The outlet opening is given a rounded or curved configuration instead of a sharp corner design. This curvature prevents liquid from pooling and blocking the opening, as the rounded shape allows liquid to flow more smoothly through the outlet without accumulating at corners or edges, thereby maintaining reliable discharge functionality.
3Adaptability or versatility
If the container is placed in non-normal positions, then handling flexibility is improved, but liquid may flow back from the receiving space to the product space
Solution Approach 1:
The resistance element is designed to create a liquid barrier that maintains its effectiveness regardless of container orientation. By positioning the resistance element to extend across the outlet opening from the receiving space side, it creates a consistent barrier that prevents liquid backflow whether the container is upright, inclined, or inverted, effectively making the liquid prevention function orientation-independent.
Solution Approach 2:
The resistance element acts as an intermediary barrier between the receiving space and the outlet opening. This intermediate structure prevents direct liquid flow from the receiving space to the product space while still allowing the outlet opening to function for liquid discharge from the product space to the receiving space in normal positions.
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 rolled rim configuration effectively prevents liquid from blocking the outlet opening, ensuring reliable discharge and separation from the product, even in non-normal positions of the container.
Implementation Method 1
The resistance element comprises a protrusion that extends toward the receiving space and surrounds the outlet opening in such a manner that the resistance element prevents the transport of liquid from the receiving space to the product space
