The bond site(s) define(s) a melt weakened region such that upon application of a force having a vector component parallel to the transverse axis, the bond site(s) fracture(s) to form a corresponding aperture in the respective web. The apertures provide a fluid communication path to facilitate delivery of the substance from the void space.
