Title: Flexible pour-spout closure for flexible package

Abstract: A pour-spout closure for use on a gusseted flexible package is provided, the package having an interior for holding some material and formed of a flexible material and including first and second panels connected to each other by respective side gussets. Each of the panels and gussets has an upper end portion, at least a portion of which conjoin to form an openable pour-through mouth for the package. When the pour-through mouth is opened, the material within the interior of the package can be poured out. The pour-spout closure is arranged for opening and re-closing the package's pour-through mouth and comprises first and second, elongated closure sections which are coupled together. The first closure section includes a first cut-away portion, and is arranged to be located, e.g, secured, on the first panel with the first cut-away portion disposed over at least a portion of the pour-through mouth. The second closure section includes a second cut-away portion, and is arranged to be located, e.g., secured, on the second panel with the second cut-away portion disposed over at least a portion of the pour-through mouth. The first and second closure sections are arranged to be moved with respect to each other, e.g., pivoted about an interconnecting hinge, into a confronting releasably secured relationship, whereupon portions of the first and second panels and the side gussets are contiguous with the pour-through mouth are positioned adjacent one another to seal said package to prevent the ingress of air into the package. The first and second closure sections are also arranged to be moved, e.g., pivoted about the hinge, into a non-confronting relationship, whereupon the pour-through spout is opened so that the material within the package can be poured therethrough.
