Abstract
In a method and apparatus wherein a container is formed, decorated by rotating the container and then the base of the contianer is cut off for a plastic tube, a container is formed with a diametral lug on the base to facilitate rotating the container during decorating. In another form, opposed diametral surfaces are provided on the lower end of the container adjacent the base. In another form, the diametral surfaces are arcuate. In another form, the lower end of the container includes a frustoconical surface. In another form, circumferentially spaced axial grooves are provided in the frustoconical surface.
