Abstract
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 The present invention thereby reduces the amount of residual liquid as the liquid is withdrawn from the bag (10) without the need for an evacuation strip or a special slanted rack.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.
