A package having a recloseable pour spout is disclosed, with the package including front and rear package panels which may be joined at respective side edges thereof by inwardly extending side gussets. An upper edge portion of the package is removable, including one of the side gussets, to form a pour spout for dispensing the contents of the package. A fastener strip, which can be detachably connected to itself, extends between confronting inside surfaces of the front and rear package panels, adjacent to the pour spout, whereby the pour spout can be conveniently closed after the package is initially opened. A method of forming the present package is also disclosed.

What is claimed is: 1. A method of forming a package with a recloseable pour spout, comprising the steps of: providing a web of material having a longitudinal axis; applying a plurality of fastener strips to said web of material at intervals corresponding to a length of each said package being formed, said fastener strips each extending transversely off center of said longitudinal axis and each consisting of a single fastener strip being detachably connectable to itself by folding and pressing against itself; folding said web of material, and sealing the material to itself to form a tube; transversely sealing said tube to form a series of packages in end-to-end relationship, with each said package including a front package panel and a rear package panel, with a respective one of said fastener strips extending from the front panel to the rear panel of the respective package to form a recloseable pour spout, and forming a pair of inwardly extending side gussets in said tube, said web of material with attached fastener strips being guided with respect to suitable plows which form said side gussets parallel to said longitudinal axis prior to said transversely sealing of the tube, each said fastener strip extending from the front panel to the rear panel of the respective package along an inside surface of a respective one of said side gussets, wherein said fastener strip has a pair of leg portions respectively extending along said front and rear panels inwardly beyond said one of said inwardly extending side gussets. 2. A method of forming a package in accordance with claim 1, wherein: said web of material is sealed to itself generally along the rear panel of each said package. 3. A method of forming a package in accordance with claim 1, wherein: said web of material is sealed to itself generally along an edge of said front panel or rear panel of each said package. 4. A method of forming a package in accordance with claim 1, wherein: said front and rear panels are sealed to each other and said side gussets at said upper edge of said package, to form a sealed header, a portion of said header being removable to form said pour spout. 5. A method of forming a package in accordance with claim 1, wherein: said removable portion of said header is formed with a laser score. 6. A method of forming a package in accordance with claim 1, wherein: said fastening strip includes at least two upstanding elements. 7. A method of forming a package in accordance with claim 1, including: forming said tube into a roll, and unrolling said tube, prior to said step of transversely sealing said tube. 8. A method of forming a package in accordance with claim 1, wherein: said removable portion of said header portion is formed with a line of perforations. 9. A method of forming a package in accordance with claim 8, wherein: said line of perforations is placed into said web of film material prior to the forming of said recloseable package. 10. A method of forming a package with a recloseable pour spout, comprising the steps of: providing a web of material having a longitudinal axis; applying a plurality of fastener strips to said web of material at intervals corresponding to a length of each said package being formed, said fastener strips each extending transversely off center of said longitudinal axis and each said fastener strip provided in the form of a single continuous preformed extruded plastic, profiled recloseable fastener strip containing at least one unisex rib and groove locking feature, said profile fastener strip including at least two upstanding elements which define a groove therebetween, said profile fastener strip being sufficiently flexible whereby said groove can receive one of said upstanding elements when said profile fastener strip is folded onto itself; folding said web of material, and sealing the material to itself to form a tube; transversely sealing said tube to form a series of packages in end-to-end relationship, with each said package including a front package panel and a rear package panel, with a respective one of said fastener strips extending from a portion of the front panel to a portion of the rear panel of the respective package to form a recloseable pour spout; forming a pair of inwardly extending side gussets in said tube, said web of material with attached fastener strips being guided with respect to suitable plows which form said side gussets parallel to said longitudinal axis prior to said transversely sealing of the tube, each said fastener strip extending from the front panel to the rear panel of the respective package along an inside surface of the respective one of said gussets, wherein said fastener strip has a pair of leg portions respectively extending along said front and rear panels inwardly beyond said one of said inwardly extending side gussets; and said front panel and rear panels are sealed to each other and said side gussets at said upper edge of said package, to form a sealed header, a portion of said header being removable to form said pour spout. 11. A method of forming a package in accordance with claim 10, wherein: said removable portion of said header portion is formed with a laser score. 12. A method of forming a package in accordance with claim 10, wherein: said removable portion of said header portion is formed with a line of perforations. 13. A method of forming a package in accordance with claim 12, wherein: said line of perforations is placed into said web of film material prior to the forming of said recloseable package. 14. A method of forming a package in accordance with claim 10, including: forming said tube into a roll, and unrolling said tube, prior to said step of transversely sealing said tube.
