Liner, preferably made of film material

Abstract

A liner to be introduced into a container has a liner wall made of a film material and a filling spout connected to the liner wall. A discharge spout is also connected to the liner wall. The discharge spout has a housing with movable holding elements for securing the discharge spout on a container. The holding elements are snap-on elements. A ring is secured to the container so as to surround a container opening. The holding elements engage the ring attached to the container for positionally securing the discharge spout on the container.
