Abstract
A flexible package is provided with a slider fastener closure. A side seal forming the package is enlarged at its upper end to provide a smooth transition of product dispensed from the package, and to shield the slider during dispensing. The enlarged side seal portion is spaced from the fastener tracks. The fastener tracks are deformed to provide a stop, spaced from the side seals, to limit slider movement. A stop of reduced area, enlarging the package opening, is made possible.
