(57) Reclosable closure assembly for containers, particularly aseptic containers, containers
having such a closure assembly, and a method for applying the closure assembly to
preformed blanks suitable for preparing the containers.
The container portion to which the closure assembly is applied has an opening, i.e.,
a pour hole. An exterior tape having a backing and an adhesive layer is attached to
the exterior container wall so as to cover the pour hole. A protective tape having
a barrier layer and an adhesive layer is firmly bonded to the interior container wall
so as to cover the pour hole. A target tape having an adhesive layer and a layer of
release coating material on a backing is disposed between the exterior tape and the
exterior container wall. The target tape has an opening coincident with the pour hole.
The protective tape is firmly bonded to the exterior tape in the area of the pour
hole and coincident opening in the target tape by means of the adhesive layers on
the exterior tape and on the protective tape. The layer of release coating material
of the target tape can come in contact with the adhesive layer of the exterior tape
so that the exterior tape can be releasably adhered to the target tape and may be
removed from and reclosed over the pour hole.
