Abstract: A bottle system includes a first housing having a first sealable opening and a distal end, between which a second sealable opening is located, and a first storage chamber being defined between the first and second sealable openings of the first housing. The bottle also includes a second housing having a second storage chamber defined between a third sealable opening and a base, with the first housing and the second housing adapted to be rotatably coupled relative to each other in an end-to-end configuration between at least a first state, in which the first and second storage chambers are separated from each other, and a second state, in which the first and second storage chambers are coterminous. The bottle also includes a cutter such that, in use, the cutter pierces seals of the second and third sealable openings as the first and the second housings are rotatably actuated.
