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.
Claims3
A dispensing cartridge for use in dispensing individual thermoplastic articles from the cartridge in seriatim order, said cartridge comprising a plurality of stacked individual thermoplastic articles, each said article having a generally planar interface between adjacent stacked articles and being formed of rigid or semi-rigid thermoplastic material, each said article being fusion bonded about its periphery to adjacent articles in the stacked relationship, the peripheral surface of said cartridge being generally continuous with said fusion bond causing no discontinuity therein produced by melting and with each said article being capable of being non-destructively sheared and separated from an end of said cartridge along said planar interface.
