ABSTRACT:
An improved method and apparatus for sealing jars and other containers within specialized environments, such as a vacuum, is provided. The containers are introduced into chambers of a rotary drum, and an outer enclosure for the drum is provided by means of a substantially flexible moving belt which conforms to the periphery of the drum and seals the chambers. A vacuum may then be introduced to the chamber to evacuate the interior of the container, and the lid of the container may then be secured to maintain the desired vacuum within the container. The flexible belt may move in synchrony with the rotation of the drum, eliminating relative motion between the outer enclosure and the drum and avoiding need for complex sliding seals. The device is quickly adaptable to sealing and closing numerous configurations and sizes of containers.
