Abstract
An improved hose is used to install loose fill insulation. The hose includes projections extending from an inner surface which serve to condition the insulation as it proceeds through the hose and is dispensed. In a first exemplary embodiment of the present invention, the projections are formed so as to be perpendicular to a longitudinal axis of the hose. In a second exemplary embodiment of the present invention, the projections are formed so as to be angled, by an angle less then ninety (90) degrees with respect to the longitudinal axis of the hose. In a third exemplary embodiment of the present invention, the projections are formed with a serrated edge. In a fourth exemplary embodiment of the present invention, the projections are formed as part of a cap member which is disposed around the periphery of the hose. In a fifth exemplary embodiment of the present invention, the projections include an additional perpendicular projection member extending therefrom.
