An interlocking pour-spout closure for a flexible, gusseted package and a flexible gusseted package including such a closure. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets. The package is initially sealed, e.g., by a peelable seal line. The panels and gussets each include a top portion. The package also includes a pour-through mouth, e.g., a portion of the panels and one side gusset is arranged to be removed from the remainder of the package. The pour-through mouth is located at the top of the package at one of the side gussets and is arranged to be opened by the pour-spout closure to provide access to the contents of the package. The closure includes a pair of closure sections hingedly secured to each other and each section includes a cut-away portion. Each of the closure sections is arranged to be secured to a respective one of the package's panels, with respective cut-away portions disposed over the at least a portion of the pour-through mouth of the package. The closure sections are arranged to disposed in a confronting releasably secured relationship with each other with portions of the first and second panels and the gussets contiguous with the package's mouth tightly interposed therebetween to close the pour-through mouth, but can be pivoted about the hinge into a non-confronting relationship, whereupon the pour-through mouth is opened so that the material within the package can be poured therethrough.
