<p>An inverting bag co-dispenser for dispensing a plurality of fluids simultaneously but separately through a spout (12) and with a predetermined discharge volume ratio for each fluid. An upper portion (10) has a spout connected to a housing (14). The housing has an outer wall (16) and a plurality of side-by-side annular members (20) depending therefrom internally to the outer wall. A plurality of fluid containing flexible bags (24) are connected to and suspended from the upper portion, one each of the bags being located inside one each of the side-by-side annular members and in fluid communication with the spout. The bags have closed bottoms (26), perimeters slidably fitting inside the annular members, and a bag wall thickness. A bottom portion (40) has a base (42) and an outer wall (44) extending upwardly therefrom. The bottom portion also has a plurality of upright posts (46) connected to the base and located inside the outer wall. The outer wall of the upper portion telescopingly engages the outer wall of the bottom portion such that one each of the plurality of posts is located axially aligned with one each of the plurality of flexible bags suspended from the upper portion. The plurality of posts are sized to cause the flexible bags to invert when the upper portion is pressed downward relative to the bottom portion to dispense fluid from the co-dispenser through the spout.</p> |
