An improved dip tube for a hand operated dispensing device is disclosed comprising a longitudinally extending dip tube having an outer surface and an inner surface for defining a wall thickness therebetween. A plurality of surface projections protrude from the outer surface of the dip tube and extend longitudinally along the dip tube. The plurality of surface projections are uniformly disposed about the dip tube for defining a plurality of recessed portions therebetween. The plurality of surface projections define major wall thickness portions for providing structural strength for the dip tube. The improved dip tube provides a conventional cross-section area of the internal channel with a reduced volume of material used in the construction of the improved dip tube.
