Baby-bottle attachment for holding dry formula separated from water in bottle has a bottom portion with internal bottle-mating threads that mate to a threaded top on a baby bottle. The attachment includes a partition having an aperture and a seal on its upper surface. The bottom portion has channels partially imbedded therein. An upper chamber has external threads that mate with a nipple. The upper chamber has a partially open bottom with an off-center aperture. A seal pad is adhered underneath the at least partially open bottom of the upper chamber. A top member has a depressible release button that extends from the end, and is attached to outer surface near the bottom of the upper chamber.

We claim: 1. A cylindrical-baby-bottle attachment comprising: (a) a cylindrical bottom with a first outside diameter and a first height defining a lower open end and an upper open end, said upper open end defining a first cross sectional area including: (i) internal bottle-mating threads at said lower open end sized to mate to a threaded top on a baby bottle; (ii) a horizontal midsection partition perpendicular to an inside wall of said cylindrical bottom above said internal bottle-mating threads and covering at least half of said first cross sectional area; (iii) a seal pad adhered to a portion of the upper surface of said midsection partition, said midsection partition further having an orifice at the center axis for a bolt; (iv) channels partially imbedded around a substantial portion of an upper inner circumference of said cylindrical bottom; (v) at least one U-shaped recess in a top rim of said cylindrical bottom; and (b) an upper chamber with each of a second height and a second cross sectional area including: (i) at least a partially open bottom end with an aperture having a third cross sectional area about 0.2 to 0.5 that of said second cross sectional area; (ii) an open top end, said open top end having external threads sized to accommodate a nipple assembly; (iii) a second seal pad adhered underneath a portion of said at least partially open bottom end and having a fourth cross sectional area at least as great as that of said third cross sectional area; (iv) at least one depressible release button attached to a distal end of a rectangular strip that extends from the outer surface of said upper chamber; (c) a bolt and nut assembly, said bolt on said bottom of said at least partially open bottom end, said nut further having a sealing washer nut; and (d) a sealing gasket attached to the underside of said midsection partition adjacent a proximal end of said bottle mating threads. 2. A cylindrical baby bottle attachment of claim 1, wherein said first diameter of said cylindrical bottom is between about 1.5 and 3.0 inches. 3. A cylindrical baby bottle attachment of claim 1, wherein said first height of said cylindrical bottom is between about 0.5 and 2.0 inches. 4. A cylindrical baby bottle attachment of claim 1, wherein said second height of said upper chamber is between about 2.0 and 4.0 inches. 5. A cylindrical baby-bottle attachment comprising: (a) a hoop-like bottom having a first height and a first outer diameter defining an at least partially open top end and an open lower end, said open lower end having internal threads sized to mate to a threaded top on a baby bottle, said at least partially open end has at least one mating cavity within an uppermost internal surface and a groove formed around an upper inner circumference beneath said cavity, said at least partially open end further has an internal flange protruding toward a center axis extending along at least half of the upper inner circumference; and (b) an upper chamber having a second height, a second central diameter and a third base diameter including: (i) a lower at least partially-open end and an open top end, said open end having external threads sized to accommodate a baby bottle nipple assembly; (ii) a semi-circular aperture having an open area about one-third to about half that of the entire cross section of said at least partially open end; (iii) at least one beveled recessed zone proximal said at least partially open end; and (iv) a cavity within each of the at least one beveled recessed zone extending radially toward the central axis; and (c) at least one spring-loaded release button assembly positioned in each of the at least one beveled recessed zone of said upper chamber, wherein each of said release buttons has an L-shaped foot engaging with each of said cavities in said hoop-like bottom. 6. A baby-bottle attachment of claim 5, wherein said first height of said hoop-like bottom is between about 0.75 to 2.0 inches. 7. A baby-bottle attachment of claim 5, wherein 10 said first outside diameter of said hoop-like bottom is between about 2.0 and 3.5 inches. 8. A baby-bottle attachment of claim 5, wherein said second height of said upper chamber is between about 2.0 inches and 4.0 inches. 9. A baby-bottle attachment of claim 5, wherein said second central diameter of said upper chamber is between about 2.0 and 3.5 inches. 10. A baby-bottle attachment of claim 5, wherein said third base diameter of said upper chamber is between about 1.5 and 3.5 inches. 11. A cylindrical baby-bottle attachment comprising: (a) a cylindrical bottom defining two substantially open ends with a first height, wherein a lower of said two substantially open ends contains internal threads sized to mate with a baby bottle; (b) a first at least partial 0-ring embedded in about one-quarter of a top rim, (c) an upper cylindrical chamber with a second height, an open upper end and an at least partially open floor, including: (i) external threads at top of said open end sized to mate with a baby bottle nipple assembly, (ii) a downward-projecting pin at a center axis of the upper chamber fused to said at least a partially open floor, (iii) an aperture in said at least partially open floor creating an open area between about one-fifth to half that of total area of said at least partially open floor, (iv) a second at least partial 0-ring embedded along about one quarter of a bottom rim of said upper cylindrical chamber, (d) a rotatable horizontal disc suspended beneath said at least partially open floor of said upper cylindrical chamber, including: (i) a seal pad adhered to an upper surface of said rotatable disc and having a similar shape to said aperture in said at least partially open floor of said upper cylindrical chamber; (ii) an aperture comparable in area and shape to that of said aperture in said at least partially open floor, (iii) a central orifice with a greater diameter than that of said downward projecting pin, and (e) a washer on the lower end of said downward-projecting pin beneath said rotatable disc. 12. A cylindrical baby bottle attachment of claim 11, wherein said first height of said cylindrical bottom is between about 0.75 and 2.0 inches. 13. A cylindrical baby bottle attachment of claim 11, wherein said second height of said upper cylindrical chamber is between about 2.0 and 4.0 inches.
