Abstract

The present invention provides tubes for, in an exemplary embodiment, dispensing loose fill insulation. The tube comprises an inner web formed in a tubular shape and having a plurality of spaced helical projections disposed along an inner surface thereof and extending towards a central longitudinal axis of the inner web, the inner surface of the inner web also forming an inner surface of the tube. A cap is disposed around an outer periphery of the inner web. The helical projections serve to condition the insulation as the insulation passes through the tube.
