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.
A pour-spout closure for use on a gusseted flexible package, the package being formed of a flexible material and comprising first and second panels connected to each other by respective side gussets, each of the panels having an upper end portion, said panels and said side gussets conjoin to form a pour-through mouth for the package, the pour-through mouth being openable from a closed state to an open state to enable material within the interior of the package to be poured out of the package, said pour-spout closure being arranged for closing and opening the pour-through mouth and consisting essentially of a first closure section and second closure section, said first closure section integral to said second closure section, coupled together by a living hinge, said first closure section including a first cut-away portion and arranged to be located on the first panel with said first cut-away portion being disposed over at least a portion of the pour-through mouth, said second closure section including a second cut-away portion and arranged to be located on the second panel with said second cut-away portion being disposed over at least a portion of the pour-through mouth, said first and second closure sections being elongated members extending substantially the width of the first and second panels, respectively, said first and second closure sections being arranged to be moved with respect to each other into a confronting, releasably secured relationship, whereupon a top surface of each of said first and second closure sections substantially abut one another such that said top surface of said first closure section is in contact with said top surface of said second closure section and 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, said first and second closure sections also being arranged to be moved into a non-confronting, non-secured relationship with each other, whereupon the pour-through mouth is opened and said first and second closure sections are separated about said living hinge such that said first and second closure sections are substantially co-planar so that the material within the package can be poured therethrough, wherein each of said elongated closure sections includes a pair of opposed side edges, a top edge, and a bottom edge, and wherein each of said cut-away portions is located adjacent to one of said opposed side edges and a contiguous portion of said top edge such that said cut-away portions form an openended spout at only one end of said pour-spout closure.
A pour-spout closure for use on a gusseted flexible package, the package being formed of a flexible material and comprising first and second panels connected to each other by respective side gussets, each of the panels having an upper end portion, said panels and said side gussets conjoin to form a pour-through mouth for the package, the pour-through mouth being openable from a closed state to an open state to enable material within the interior of the package to be poured out of the package, said pour-spout closure being arranged for closing and opening the pour-through mouth and comprising a first closure section and second closure section, said first closure section integral to said second closure section, coupled together by a living hinge, said first closure section including a first cut-away portion and arranged to be located on the first panel with said first cut-away portion being disposed over at least a portion of the pour-through mouth, said second closure section including a second cut-away portion and arranged to be located on the second panel with said second cut-away portion being disposed over at least a portion of the pour-through mouth, said first and second closure sections being elongated members extending substantially the width of the first and second panels, respectively, said first and second closure sections being arranged to be moved with respect to each other into a confronting, releasably secured relationship, whereupon a top surface of each of said first and second closure sections substantially abut one another such that said top surface of said first closure section is in contact with said top surface of said second closure section and 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, said first and second closure sections also being arranged to be moved into a non-confronting, non-secured relationship with each other, whereupon the pour-through mouth is opened and said first and second closure sections are separated about said living hinge such that said first and second closure sections are substantially co-planar so that the material within the package can be poured therethrough, wherein said first cut-away portion is a plurality of holes adapted to be disposed over at least a portion of the pour-through mouth, and wherein said second cut-away portion is a plurality of holes over at least a portion of the pour-through mouth.
