Abstract: The invention is directed to a system and method for sealing a closure to a container comprising a die assembly, a mandrel assembly, and a gas evacuation assembly. The mandrel assembly comprises an outer mandrel and an inner mandrel. The outer mandrel is configured to vertically translate and constrain a closure in position. The gas evacuation assembly, which comprises at least one interior channel within the die and one or more channel openings into the interior of the die, suctions gas from the interior of an aligned container when the closure is constrained in position. The inner mandrel translates vertically to insert the closure into the container and a sealing member seals the closure in place.

Abstract: The invention is directed to a system and method for hermetically sealing a closure to a container comprising a die assembly and a mandrel assembly. The mandrel assembly comprises an outer mandrel, an inner mandrel, and an ejector disposed within an inner circumference of the inner mandrel. At least the outer mandrel is configured to translate a first distance in a first time period, the inner mandrel and the ejector are configured to translate a second distance in a second time period, the inner mandrel is configured to retract a third distance in a third time period, and the ejector is configured to retract the third distance in a fourth time period.

Abstract: The present disclosure is directed to recyclable, composite container assemblies with improved characteristics resulting from a combination of raw materials, structural design, systems, and methods for sealing a paper-based closure to a paper-based container body. The container assemblies demonstrate superior performance and seal properties, such as very low oxygen transmission rates and high resistance to bulging and/or damage due to high pressure differentials. The disclosed container assemblies, manufactured at high speeds, have been optimized by increasing the shelf-life of food products stored therein, while minimizing any non-paper materials such that the container assemblies qualify as recyclable mono-material.

The mandrel assembly comprises an outer mandrel and an inner mandrel. The outer mandrel is configured to vertically translate and constrain a closure in position. The gas evacuation assembly, which comprises at least one hollow channel within the die and one or more channel openings into the interior of the die, suctions gas from the interior of an aligned container when the closure is constrained in position. The inner mandrel translates vertically to insert the closure into the container and a sealing member seals the closure in place.
