Abstract
Abstract A reclosable package has a generally rectangular outer wrapper including a top closure formed of panels folded to one another and against a top face of the package; a flap constituting a continuation of one of the panels; and a hook-and-eye fastener having hook and eye components attachable to and separable from one another. One of the components is permanently affixed to a face of the flap and the other component is readily removably carried on the one component. After an initial opening of the package, one fastener component is transferable from the other for permanent attachment to the wrapper, and the flap may be positioned over the wrapper such that the fastener components are in alignment for engagement with one another.
