IMPROVEMENT TO HOSE USED TO INSTALL LOOSE FILL INSULATION |
摘要 |
An improved hose is used to install loose fill insulation. The hose includes projections (140) extending from an inner surface which serve to condition t he insulation as it proceeds through the hose and is dispensed. In a first embodiment of the present invention, the projections are formed so as to be perpendicular to a longitudinal axis of the hose. In a second embodiment of the present invention, the projections (140') are formed so as to be angled, by an angle less than ninety (90) degrees with respect to the longitudinal axis of the hose. In a third embodiment of the present invention, the projections (141) are formed with a serrated edge. In a fourth embodiment of the present invention, the projections (142) are formed as part of a cap member which is disposed around the periphery of the hose.
