This invention is directed to an improved bag-in-box apparatus for containing and dispensing liquids such as beverages. The interior surface of the bottom of the box ( 20 ) is preferably sloped downward toward the spout ( 12 ) of the bag ( 10 ) such that gravity helps feed the liquid toward the spout ( 12 ). In lieu of or in conjunction with slopes, the interior bottom surface of the box ( 120, 130, 150, 140, 160 ) may have terraces ( 34 ), curves ( 132, 134 ), corrugations ( 152 ), fan-like ridges ( 142 ), or beams ( 162 ). The present invention thereby reduces the amount of residual liquid as the liquid is withdrawn from the bag ( 10 ) without the need for an evacuation strip or a special slanted rack. Although the primary intended application of the present invention is in bag-in-box packages for containing and dispensing beverages, this invention may also be used to advantage in other liquid dispensing applications.

1. A box for receiving a collapsible bag, the bag having a spout and being capable of containing and dispensing a liquid, said box comprising:an interior bottom surface for supporting the collapsible bag, said interior bottom surface comprising a first location and a second location, there being a difference in elevation between said first and second locations, said interior bottom surface having at least one portion selected from the group consisting of terrace, corrugation, fan, and beam; anda wall adjacent said interior bottom surface, said wall having an opening for receiving the spout of the collapsible bag;wherein a liquid contained in the collapsible bag will be urged toward the spout under the influence of gravity due to said difference in elevation. 2. The box of claim 1 wherein said interior bottom surface further comprises at least one slope. 3. The box of claim 2 wherein said at least one slope comprises a lateral slope. 4. The box of claim 2 wherein said at least one slope comprises a longitudinal slope. 5. The box of claim 2 wherein said at least one slope comprises a lateral slope and a longitudinal slope. 6. The box of claim 1 wherein said interior bottom surface is integral to said box. 7. The box of claim 1 wherein said interior bottom surface is provided by an insert to said box. 8. The box of claim 1 further comprising a substantially horizontal exterior bottom surface. 9. The box of claim 1 wherein said difference in elevation allows substantially complete withdrawal of liquid from the collapsible bag. 10. A bag-in-box apparatus for containing and dispensing a liquid, said apparatus comprising:a collapsible bag having a spout; anda box comprising an interior bottom surface having a first location and a second location, there being a difference in elevation between said first and second locations, said interior bottom surface having at least one portion selected from the group consisting of terrace, corrugation, fan, and beam, said box further comprising a wall adjacent said interior bottom surface, said wall having an opening therein, said collapsible bag being disposed within said box, said spout being disposed through said opening in said wall;wherein a liquid contained in said collapsible bag will be urged toward said spout under the influence of gravity due to said difference in elevation. 11. The apparatus of claim 10 wherein said interior bottom surface further comprises at least one slope. 12. The apparatus of claim 11 wherein said at least one slope comprises a lateral slope. 13. The apparatus of claim 11 wherein said at least one slope comprises a longitudinal slope. 14. The apparatus of claim 11 wherein said at least one slope comprises a lateral slope and a longitudinal slope. 15. The apparatus of claim 10 wherein said interior bottom surface is integral to said box. 16. The apparatus of claim 10 wherein said interior bottom surface is provided by an insert to said box. 17. The apparatus of claim 10 wherein said box further comprises a substantially horizontal exterior bottom surface. 18. The apparatus of claim 10 wherein said difference in elevation allows substantially complete withdrawal of liquid from said collapsible bag. 19. The apparatus of claim 10 wherein said bag comprises a stiffener that cooperates with said interior bottom surface as said bag collapses to allow substantially complete withdrawal of liquid from said bag. 20. The apparatus of claim 10 wherein said box has a top and said bag is attached to said top. 21. A box for receiving a collapsible bag, the bag having a spout and being capable of containing and dispensing a liquid, said box comprising:an insert forming an interior bottom surface of said box for supporting the collapsible bag, said interior bottom surface comprising a first location and a second location, there being a difference in elevation between said first and second locations, said interior bottom surface having at least one portion selected from the group co nsisting of terrace and corrugation; anda wall adjacent said interior bottom surface, said wall having an opening for receiving the spout of the collapsible bag;wherein a liquid contained in the collapsible bag will be urged toward the spout under the influence of gravity due to said difference in elevation. 22. A bag-in-box apparatus for containing and dispensing a liquid, said apparatus comprising:a collapsible bag having a spout; anda box comprising an insert which forms an interior bottom surface having a first location and a second location, there being a difference in elevation between said first and second locations, said interior bottom surface having at least one portion selected from the group consisting of fan and beam, said box further comprising a wall adjacent said interior bottom surface, said wall having an opening therein, said collapsible bag being disposed within said box, said spout being disposed through said opening in said wall;wherein a liquid contained in said collapsible bag will be urged toward said spout under the influence of gravity due to said difference in elevation. 23. A bag-in-box apparatus for containing and dispensing a liquid, said apparatus comprising:a collapsible bag having a spout and a stiffener; anda box comprising an interior bottom surface having a first location and a second location, there being a difference in elevation between said first and second locations, said box further comprising a wall adjacent said interior bottom surface, said wall having an opening therein, said collapsible bag being disposed within said box, said spout being disposed through said opening in said wall;wherein a liquid contained in said collapsible bag will be urged toward said spout under the influence of gravity due to said difference in elevation and wherein said stiffener cooperates with said interior bottom surface as said bag collapses to allow substantially complete withdrawal of liquid from said bag. 24. The apparatus of claim 23 wherein said stiffener is substantially flat.
