Abstract
An enlarged dispensing pouch for holding viscous food product for dispensing from a specific hand held or similar type dispenser, is formed so as to include a tear strip which will accurately and consistently open a funnel-shaped, centrally disposed outlet spout formed in the pouch. The tooling to form the tear-off strip across the pouch and up to the outlet spout includes a plurality of blade groupings having specifically sized and shaped blades to form a predetermined number of enlarged perforations and smaller end perforations along the tearline of pouches to enable the tear strips so formed to be accurately and consistently torn off the pouches.
