Top-Engaging Carriers for Cylindrical Package Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging solutions for cylindrical articles, such as beverage cans, require complex construction methods and materials, leading to inefficiencies in material usage and stability, particularly for sleek or slim designs where variations in diameter are minimal.
Innovation Solution
A device comprising a metering base and an applicator plate that simultaneously applies top-engaging carriers to groups of articles, utilizing a spacer structure for spacing and alignment, and an applicator plate with cavities to receive article tops, allowing for the formation of discrete packages by severing frangible connections between connected blanks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex construction methods and materials are used for packaging cylindrical articles, then the strength and stability of the package is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The packaging system is divided into modular components: individual article carriers with aperture structures, top-engaging carriers that wrap around groups of articles, and frangibly connected blanks that can be separated into discrete packages. This segmentation allows each component to be optimized independently while maintaining overall strength.
Solution Approach 2:
The apparatus pre-arranges multiple articles in groups within a metering base before applying the top-engaging carriers. The metering base with spacer structures and aligning features positions articles in advance, eliminating the need for complex real-time adjustment mechanisms during package formation.
2Loss of substance
If traditional packaging methods are used for sleek or slim cylindrical articles, then the articles are contained, but material waste increases due to minimal diameter variations
Solution Approach 1:
The top-engaging carriers feature aperture structures with tabs positioned at specific locations to engage with the flange or lip of each article. The carrier material is distributed locally only where needed for engagement, rather than using solid continuous material, reducing waste while maintaining retention reliability for sleek articles with minimal diameter variations.
Solution Approach 2:
The aperture structures and tab configurations can be adjusted to match the specific dimensions of sleek or slim cylindrical articles. The carrier design accommodates minimal diameter variations by optimizing the aperture size and tab engagement geometry, ensuring reliable retention with minimal material usage.
3Productivity
If multiple articles are packaged individually, then each article is securely contained, but the productivity and efficiency of the packaging process decreases
Solution Approach 1:
Multiple article carriers are connected by frangible connections forming a single integrated blank structure. The apparatus applies top-engaging carriers to multiple groups of articles simultaneously in a single operation, dramatically improving productivity while the frangible connections allow easy separation into individual discrete packages if needed.
Solution Approach 2:
The metering base with spacer structures and aligning features pre-positions multiple groups of articles in the correct configuration before the top-engaging carrier is applied. This preliminary alignment ensures that all articles are correctly positioned in a single setup, enabling simultaneous packaging of multiple articles without compromising alignment precision.
4Loss of substance
If frangibly connected blanks are used to form discrete packages, then material usage is optimized, but the reliability of maintaining package integrity during handling decreases
Solution Approach 1:
The frangible connections are designed with controlled weakness points that allow easy separation when needed, but the overall blank structure maintains sufficient strength to protect articles during normal handling and transport. The carrier material and connection geometry are optimized to provide cushioning and protection before separation is required.
