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.

[ We claim:] [1.] The method of forming a flexible plastic tube for use in dispensing a viscous product which comprisesinjection molding a neck finish having a shoulder portion and an opening in said neck finish,extruding a tube portion integrally with the finish by relative movement of the finish with respect to an extruder,moving the finish axially away from the extruder while continuously extruding said tube portion,closing a blow mold about the extruded tube portion,blow molding said tube portion into an integral container body having a closed bottom,opening the molds to provide an integral container having an integral finish, a shoulder portion, a tubular body portion having a lower end and the closed bottom,said step of blow molding further comprising providing a single diametrical lug on said closed bottom of said container extending the entire length of the closed bottom of the container along the diameter of the closed bottom,causing said container to rotate by engaging said diametrical lug with a rotating complementary lug,decorating the body portion with indicia while engaging said neck finish and engaging said diametrical lug and rotating the container, andthereafter cutting off the closed bottom of the container leaving a flexible plastic tube having a finish, a shoulder portion and a flexible tube portion having an open end.
