Method and apparatus for reforming can bottom to provide improved

A method of hot filling a plastic container includes the steps of introducing a heated product into the container at a temperature of about 190.degree. F., introducing liquid nitrogen into the container and sealing the container before any significant thermal distortion occurs and cooling the container to room temperature, while maintaining a positive pressure within the cooled container.

Method of packaging products in plastic containers

A system for introducing liquified gas into filled containers in a continuous container fill line (10), wherein, the dosage of liquified gas dispensed into each container is calibrated to the individual container's particular head-space volume. The system (10) includes measuring the head-space volume of each filled container in-line and communicating that measurement to a controller (28) which can adjust the dosage of liquified gas to be dispensed to each individual container. The system also provides for measuring the internal pressure of each container after sealing, which measurement is also communicated to the controller so that the controller can make additional dosage corrections and can direct the ejectment of improperly pressurized containers.

Head-space calibrated liquified gas dispensing system

A container for vacuum packaging of products includes an outer container and an inner liner which conforms generally to the configuration of the outer container and is secured to the upper open end thereof while the remainder of the container and liner are unattached. A vent is provided between the atmosphere and the space between the container and liner so that the liner can expand and collapse as differential pressures are applied to the product sealed in the liner by a plastic film secured open end thereof.
