Abstract
An open ended carton which includes a recessed moisture barrier closure provided by a membrane liner and an overlying cover. The membrane liner includes a perforated cut-out area which defines a pour spout. The cover which is affixed to the cut-out area by a heat seal pivots outwardly about a transverse score line to sever the perforations. Areas in the cover which surround the cut-out perforations in the membrane are releasably sealed to the membrane, such that outward pivoting of the cover severs the perforations and peels the seal open to provide a pour spout.
