An improved tube for handling fluent materials such as caulking includes a plurality of ribs that form air escape spaces. The ribs extend inwardly from an inner peripheral wall of the tube for a very small distance. The ribs form an ai r space between a plunger and the tube allowing air to escape rearwardly of the plunger. In another feature of this invention, a color plastic sleeve is receive d on a nozzle for the tube to provide an identification of the color of the caulking received within the tube.
