  • Dual chamber storage device
    Patent number: 10640276
    Abstract: A dual chamber storage device includes a first chamber having a base and a hollow body for storing a first material. A second chamber within the hollow body of the first chamber has a base, a hollow body for storing a second material, and a neck portion. A dispenser housed within the second chamber has a hollow body, a dispensing tip, and a cutting edge. A cap surrounds the end of the dispenser with the cutting edge, is rotatingly connectable with the second chamber neck portion, and is non-rotatingly connectable with the first end of the dispenser. When the cap is rotated relative to the second chamber neck portion, the second end of the dispenser moves toward the base of the second chamber and the cutting edge pierces the base of the second chamber thereby allowing the second material to enter the hollow body of the first chamber.
