Abstract: A bottle (12), which has a single circular opening (12f) at the top (12e), contains a liquid (32) in a bottom chamber (12h) and a powder (26) in an upper chamber (12d). A rubber stopper (14) exists in a neck chamber (12g) between the upper (12d) and lower (12h) chambers and isolates the liquid (32) from the powder (26). The neck chamber (12g) has a smaller cross-sectional area than the lower chamber (12h). A cylindrical basket (16) with openings in the side walls (16a) sits on top of the rubber stopper (14). A cylindrical rubber dispenser plunger (18) having a sealing portion (18a) sits above the basket (16). A locking cap (22) sits on top of the dispenser plunger (18). A septum cap (24) having vent holes (24c) sits on top of the locking cap (22 ). A sealing disc (26) sits on top of the septum cap (24). A cup-like top cap (28) covers the top of the bottle (12). Shrink wrap (32) adheres to the top cap (28) and part of the outside of the bottle (12).
