Abstract
A dispensing cartridge comprising a plurality of stacked individual articles formed of rigid or semi-rigid thermoplastic material, each article being fusion bonded at its periphery to adjacent articles in the stacked relationship. The cartridges are formed by passing a stack of the articles through a heating zone to fusion bond the articles one to the other without producing any visual discontinuity about the periphery of the cartridge.
