A four corner bag constructed of flexible thermoplastic sheet or film material having overlying front and rear wall panels and a bottom sealed end. The upper portion of the bag includes a first closure region terminating in a top sealed end, a second closure region disposed inwardly of the top sealed end, and a perforated seal or tear strip extending across the width of the bag and located between the first and second closure regions. The second closure region includes an inner heat seal which extends approximately halfway across the width of the bag and a reclosable fastener which extends the remaining distance across the bag. In one embodiment, the inner heat seal is oriented transversely across the bag while the reclosable fastener is upwardly angled so that it forms a natural pour spout during use. In other embodiments, the reclosable fastener is transversely oriented while the inner heat seal is angled. In still other embodiments, the reclosable fastener is vertically or longitudinally oriented and disposed adjacent a side edge at an upper corner region of the bag. In all embodiments containing a reclosable fastener, the tear strip is removed to access the reclosable fastener.

The bag according to claim 2 wherein said second side edges of said front and back wall panels further include a tear strip adjacent said opening of the bag so that removal of said tear strip allows access to said reclosable closure, and opening said reclosable closure forms a pour spout permitting contents contained within the bag to be poured therefrom.4. The bag according to claim 2 wherein said reclosable closure is disposed inwardly relative to the second edges of said first and second wall panels of said bag.5. The bag according to claim 1 wherein said second side edges of said front and back wall panels further include a tear strip adjacent said opening of the bag so that removal of said tear strip allows access to the bag and said opening forms a pour spout permitting contents contained within the bag to be poured therefrom.6. The bag according to claim 5:further comprising a reclosable closure inside said tear strip and inserted into the opening defined along said second side edges of said front and back wall panels between said top edges of said front, back and second gusseted side panels, said reclosable closure sealed to an inner surface of each of said front and back wall panels and the top edges of said front, back and second gusseted side panel adjacent said opening; and wherein when said closure is closed said pouch of the bag is closed and when said closure is open any contents within the pouch are pourable from the bag. 7. The bag according to claim 6 wherein said reclosable closure is disposed inwardly relative to the second edges of said first and second wall panels of said bag.8. The bag according to claim 1 wherein said first and second gusseted side panels include fold lines that define a center line between said first and second side edges extending downward from said top edge; a triangle extending upward from said bottom edge having a highest point from said bottom edge centered between said first and second side edges with a height from the bottom edge being one half a length of said bottom edge; and said center line meeting said highest point of said triangle.9. A flexible bag for packaging pourable contents such as dry cereal, the bag being formed of sheet material and comprising:front and back wall panels each having a polygonally shaped surface and top, bottom, and first and second side edges, for each of said wall panels said first and second side edges are parallel to each other with said second side edge being longer than said first side edge; said bottom edge is perpendicular to one end of each of said first and second side edges; said top edge intersects another end of each of said first and second side edges with an included angle other than 90°; said top edge is longer than said bottom edge; and each of said first and second side edges is longer than each of the top and bottom edges; a first gusseted side panel having a bottom edge, and first and second side edges with a length of said first and second side edges of said first gusseted side panel and said first edges of said back and front wall panels being the same length; a second gusseted side having a bottom edge, and first and second side edges with a length of said first and second side edges of said second gusseted side panel being at least two thirds the length of said second edges of said back and front wall panels; and a bottom panel having a rectilinearly shaped surface with front, back, and first and second side edges, said front and back edges being opposite each other and said first and second side edges being opposite each other; said front and back edges being the same length as said bottom edges of said front and back wall panels; and said first and second side edges being the same length as said bottom edges of said first and second gusseted side panels, respectively; and wherein said front and back edges of said bottom panel and said bottom edges of said front and back wall panels are sealed together, respectively; said first and second side edges of said bottom panel and said bottom edges of said first and second gusseted side panels are sealed together, respectively; said first side edge of each of said front and back wall panels and said first and second side edges of said first gusseted side panel are sealed together, respectively; said top edges of said front and back wall panels are sealed together; and said first and second side edges of said second gusseted side panel, beginning at the bottom edge of said second gusseted side panel, are sealed to said second side edges of said front and back wall panels, respectively, forming a pouch between interior surfaces of each of said front and back wall panels, said bottom panel and each of said first and second gusseted side panels with an opening defined along the second side edges of said front and back wall panels extending between the top edges of the front and back wall panels and a top point of said second gusseted side panel. 10.
