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.

A carton which comprises: an open ended body portion formed by an upright boundary wall, and a top end peripheral edge which define the carton opening; a first flange at the peripheral edge; a cover having an interior surface, first and second attachment sections which are hingedly connected by a transverse score line, and release means for pivotal movement of said second attachment section about the transverse score line, said cover having a dimension substantially equal to that of the carton opening; and a membrane liner including interior and exterior sides, a central area bounded by a central edge having substantially the same dimension as the cover, a perforated cut out area located in said central area which defines a pour spout, and means for securing the membrane to the carton, said means for securing the membrane to the carton including a second flange which extends outwardly from the central edge, said first flange being folded inwardly and overlapping said seocnd flange to effect a recessed attachment of said membrane and cover to the carton, said cut-out area being defined by rear and connecting boundary perforation lines, said interior surface of said cover being disposed in overlying relation with respect to said central area with said rear perforation and transverse score lines substantially coinciding, said first section being affixed to said membrane, said second attachment section overlying and being affixed to said cut-out area, so that said second attachment section is maintained in closed orientation with respect to said carton opening by the attachment of said cut-out area, readily pivoting outwardly about said transverse line to provide a pour spout when the cut-out area perforations are broken, said second section pivoting through substantially 180 degrees to overlie said first section and releasably engage said first flange to provide unobstructed access to said pour spout, said second section pivoting to overlie said pour spout and releasably engage said first flange to provide a reclosure feature.
