ABSTRACT:
An aseptic pour spout seal for a flat top end closure having two oppositely disposed outer closure panels, and two oppositely disposed fold-in panels, one of which serves as the pour spout when opened. Each of the fold-in panels includes a substantially triangular panel portion, and a pair of fold-back panels integrally connected to and folded between the substantially triangular panel portion and the respective adjacent outer closure panels. Diagonal opening-assist score lines are formed on the outer closure panels adjacent the respective fold-back panels. An abhesive release coating is applied to the outside surfaces of the pour spout, and to the inside surfaces of either the pair of fold-back pour panels or the adjacent areas defined by the diagonal opening-assist score lines. A suitable sealant is overlain on the abhesive release coating on the pair of fold-back pour panels or the adjacent areas.
