An upright product outlet bag evacuation packaging (100, 200) includes a flexible, collapsible bag (101, 201) and a spout (116, 216) that contains and dispenses a liquid (118, 218). The bag (101, 201) includes a first wall (102, 202) and a second wall (104, 204) that are operatively connected by a seam (106, 206). When the bag (101, 201) is filled with liquid (118, 218), the first wall (102, 202) and the second wall (104, 204) are pushed away from one another thereby pulling a first side (109, 209) inward and causing an indentation (114, 214) to form. The indentation (114, 214) hinders flush contact between the first wall (102, 202) and the second wall (104, 204) as the bag (101, 201) progressively collapses as the liquid (118, 218) is dispensed. A housing (300, 400) for use with a dispenser may be used to create and reinforce the indentation (114, 214). The housing (300, 400) includes a cavity (303, 403) configured and arranged to receive the bag (101, 201). A door (302, 402) is operatively connected to the housing and includes a bar member (304, 404) which extends into the cavity (303, 304). The bar member (304, 404) contacts the bag (101, 201) with the cavity (303, 304) to create and reinforce the indentation (114, 214).
