A bag-in-box apparatus for containing and dispensing a liquid, said apparatus comprising:

• a collapsible bag having a spout;
• and
• a 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, curve, 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.

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;
• and
