ABSTRACT:
This invention involves a tapered vacuum bag sealer that can be used to seal conventional plastic bags and to vacuum canning jars or other food containers. The rear of the sealer housing has a connection for a PVC tube or other flexible tube that will extend to the jar or container being vacuumed to remove air therefrom. This rear connection avoids the necessity of the housing lid being opened before this vacuum procedure could be accomplished.
