A storing and mixing container and method for separately depositing and separately storing a first substance and a second substance in a container and mixing the substances together at the time of use. 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 seal between the top portion and the bottom portion. The breakable interior seal is positioned on an opposite plane to the crimp seal. Coated to the interior wall surface of the container is a weak sealant material applied during or after the container making process by means of spraying, swabbing, painting or by other such coating or layering techniques known to the industry. The breakable interior seal separates the top portion and the bottom portion of the container into two separate chambers and is formed by applying pressure to and transmitting heat through the opposite sides of the exterior container wall surface causing the interior sealant-coated wall surface to make contact and melt at all points of contact. When melted and immediately cooled, the sealant coating congeals and adheres at all points of contact between the interior wall surface to form a breakable interior seal. The extreme bottom end of the container is sealed using crimp sealing or other permanent sealing techniques known to the industry. At the time of filling, the container is inverted and comprises a cap closure at one end in a downward facing position and an opening at the opposite end in an upward facing position. The first substance is deposited into the lower portion of the inverted container through the opening. Using means known to the industry, pressure is applied to and heat is transmitted through the external walls of the container above the level of the first substance, thereby causing the interior sealant-coated walls to melt at all points of contact. Using cooling techniques known to the industry, the melted sealant is immediately cooled causing the sealant to congeal and harden and to form an interior breakable seal. The interior breakable seal separates and seals off the first substance inside a first chamber. The second substance is deposited into the upper portion of the inverted container through the opening. The second substance is sealed off inside a second chamber by closing the container opening using crimp sealing or other permanent sealing techniques. The breakable interior seal and the crimp seal are positioned on opposite planes to allow for maximum substance volume inside the container. The container is bent along or beside the crease of the interior breakable seal until the two chambers are in a substantially side by side v-shape position. The two chambers may be held in a substantially side by side v-shape position by a breakable exterior contact seal located at a point where the two chambers make side by side contact. When a user desires to mix the first substance and second substance together, the user unbends and squeezes the container causing the interior breakable seal to break and the substances to interact. When the user agitates the container, the first and second substances are mixed together.
