Customer Container Handling Challenge 

A food manufacturer needed a way to verify the seal integrity of their 42-ounce jars of raspberry spread. The solution had to gently and reliably invert the jars to allow product contact with the lid—helping to identify potential seal issues—without compromising label quality or production throughput.

Morrison Solution 

Morrison engineered a mechanical system designed to accept upright jars at line speed, invert them 90 degrees to enable lid contact with the contents of the containers, and then return them to the upright position for downstream processing. The application leveraged Morrison’s proven expert techniques for delicate products requiring careful and precise handling.

Construction 

The system features a Power Twist unit and two Timing Screws configured to manage container progression through the inverting process. Constructed of stainless steel and Ultra High Molecular Weight Polyethylene (UHMW) plastic, these components were selected for their durability, providing consistent container control through each stage of the process.

Results

With this solution, the manufacturer gained an automated mechanical method for checking seal integrity inline, supporting their quality assurance efforts. The system operates in sync with existing production speeds and is designed to handle jars with care throughout the inverting process.
