Two or more containers (1,2) converge above the grip hole or are again divided into separate chambers (1',2'). There may be a dividing wall (5) above the grip hole, and in this case the bottle is fitted with valves or slides to open and close the respective chambers. Additional components include the teat (4) and valve etc. with a fitted seal (3) for chamber control thus permitting individual or conjoint chamber use. The bottle may be made with optional metal or plastics finish.
