Abstract
The top seal parts of bottle-like containers made by blow-molding a flexible synthetic resin are cut off by nonrotatably supporting each container, pressing from one side a cutting edge of a cutter against a specific cutting line on the top part of the container, and rotating the cutter around the top part thereby to cut off the top seal part. This process can be carried out by an apparatus comprising a plurality of combinations of mechanisms, each combination comprising a fixing device for nonrotatably and fixedly supporting a container, a cutting head which can be fitted onto the top seal part of this container and can be driven in ascending, descending, and rotating movement, and cutting head drive.
