Abstract: A storing and mixing container and method for separately depositing and storing a first substance and a second substance in separate chambers and for mixing the substances together at the time of use by breaking the barrier between the separate chambers. The container comprises a cap at one end through which the contents of the container are emptied defined as the top portion, a crimp seal at the other end defined as the bottom portion and a breakable interior barrier seal between the top portion and the bottom portion. The interior barrier seal separates the top portion and the bottom portion of the container into two chambers. To maximize the substance volume within the container, the interior barrier seal is positioned at right angles and on an opposite plane to the crimp seal. The barrier can be broken by the application of external pressure to the outer walls of the container.
