Abstract
A reclosable package comprises a receptacle having first and second walls, respective mouth portions of the front and rear walls forming a mouth that communicates with an interior volume of the receptacle; a zipper having mutually interengageable zipper strips, one zipper strip being joined to the mouth portion of the front wall and the other zipper strip being joined to the mouth portion of the rear wall; a slider mounted to the zipper, the slider initially being parked in a position whereat the zipper is closed along a majority of its length; and a tack seal that resists movement of the slider in an opening direction from the initially parked position. The tack seal is designed to rupture and no longer resist slider movement when a predetermined threshold level of force is exerted by the slider.
