Our client came to us with a specific need to develop a unique closure design for one handed use that would also be easy to open. We answered the challenge by designing this closure with a complex parting line allowing for maximum leverage which allowed precise control for the opening force. A simple flip of the thumb to open the closure and an air tight seal after snapping it closed. Our knowledge of industry standards combined with expertise in the design for thin wall, high cavitation, maximum profit closures is why our clients consistently leverage our capabilities.
