Abstract

A reclosable package comprises first and second opposing body panels, a reclosable seal and a one-time breakable element. The reclosable seal extends along one end and includes first track and second tracks. The first track includes a first fin portion and a first reclosable element. The first fin portion has a first end and a second end that is further from the first reclosable element. The one-time breakable element comprises first and second sections and initially extends from the first fin portion to the second fin portion. Each of the first and second sections extends upwardly and inwardly from near the respective second ends of the first and second fin portions so as to form a generally inverted U-shaped or V-shaped cross-sectional configuration. The first and second opposing body panels are attached to respective first and second sections of the one-time breakable element.
