Claim 1
Independent Claim
97 words
A process for dispensing individual thermoplastic articles, said articles being arranged in a stacked relationship for seriatim dispensing of individual articles, said individual thermoplastic articles having a generally planar interface between adjacent stacked articles and being bonded together, by a fusion bond between individual thermoplastic articles to form a unitary self-supporting cartridge for dispensing, comprising the steps of: placing said cartridge within a dispensing magazine; and shearing individual articles one at a time from said cartridge in a direction substantially parallel to said planar interface with said shearing action severing said fusion bond without generating extraneous material.
