Abstract
Abstract A pad dispensing device includes a receptacle having a dispensing slot in its top wall and a stack of pads contained in the receptacle, the pads being interconnected by elongated pull tabs having transverse lines of weakness at their junctions with the leading pads. The stack of pads is formed of a continuous web including longitudinally spaced pads which may be circular or other shapes, successive pads being connected by intervening elongated tabs, and the web being accordian folded to superimpose the pads. The pads are impregnated with an active ingredient. The leading tab projects through the dispensing slot and as a pad is withdrawn the next pull tab is exposed.
