Dual chamber storage device
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.
1. A dual chamber storage device comprising:
a first chamber comprising:
a base; and
a hollow body configured to store a first material;
a second chamber housed within the hollow body of the first chamber, the second chamber comprising:
a base;
a hollow body configured to store a second material; and
a vent configured to permit venting of the first material in the first chamber while simultaneously isolating the first material from the second material;
a dispenser housed within the second chamber, the dispenser comprising:
a hollow body;
a dispensing tip provided on a first end of the hollow body; and
a cutting edge provided on a second end of the hollow body, the second end being opposite to the first end; and
a cap configured to surround the second end of the dispenser so as to seal the dual chamber storage device.
2. The dual chamber storage device of claim 1 , wherein:
the cap is rotatingly connectable with the second chamber neck portion and non-rotatingly connectable with the first end of the dispenser; and
when the cap is rotated relative to the second chamber, 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.
3. The dual chamber storage device of claim 1 , wherein the first chamber further comprises a first sealing portion; and
wherein the hollow body of the second chamber comprises a second sealing portion engageable with the first sealing portion so as to form a fluid-tight seal.
4. The dual chamber storage device of claim 3 , wherein the second chamber comprises a third sealing portion, and the hollow body of the dispenser comprises a fourth sealing portion engageable with the third sealing portion to form a second fluid-tight seal.
5. The dual chamber storage device of claim 1 , wherein the vent is positioned outside of the hollow body of the second chamber.
6. The dual chamber storage device of claim 1 , wherein the second chamber is sealingly connected to the hollow body of the first chamber through a seal and the vent is positioned below the seal.
7. The dual chamber storage device of claim 1 , wherein the first material is a lyophilized material or a material configured to be lyophilized and the second material is a liquid.
8. The dual chamber storage device of claim 1 , wherein the dispenser comprises a dispensing tip that is sized and shaped to deliver a mixture of the first material and the second material in an amount of between about 1 microliters and 100 microliters.
9. The dual chamber storage device of claim 1 , wherein the dispenser comprises a dispensing tip that is sized and shaped to deliver a mixture of the first material and the second material in an amount of between about 1 microliters and 20 microliters.
10. The dual chamber storage device of claim 8 , wherein the dispensing tip has a top surface and an aperture, the aperture being recessed from the top surface.
11. A method of delivering a homogenized mixture of two materials, the method comprising:
providing a dual chamber storage device comprising;
a first chamber comprising:
a base; and
a hollow body configured to store a first material;
a second chamber housed within the hollow body of the first chamber, the second chamber comprising:
a base;
a hollow body configured to store a second material; and
a vent;
a dispensing tip provided on a first end of the hollow body; and
a cutting edge provided on a second end of the hollow body, the second end being opposite to the first end;
venting the first material in the first chamber through the vent while simultaneously isolating the first material from the second material;
deforming the second chamber so as to deliver the second material into the first chamber;
mixing the first material with the second material; and
inverting the dual chamber storage device to deliver a homogenized mixture of the first material and the second material.
12. The method of claim 11 , wherein the venting comprises venting the first material in the first chamber during lyophilization.
13. The method of claim 11 , wherein deforming the second chamber comprises deforming a base of the second chamber using the cutting edge of the dispenser.
14. A dual chamber storage device comprising:
a first chamber comprising:
a base; and
a hollow body configured to store a first material;
a second chamber housed within the hollow body of the first chamber, the second chamber comprising:
a base;
a hollow body configured to store a second material; and
a vent that permits venting of the first material in the first chamber while simultaneously isolating the first material from the second material;
a dispenser housed within the second chamber, the dispenser comprising:
a hollow body;
a dispensing tip provided on a first end of the hollow body, the dispensing tip dispensing tip comprising a top surface and an aperture, the aperture being recessed from the top surface, the aperture being sized and shaped to deliver a mixture of the first material and the second material in an amount of between about 1 microliters and 100 microliters;
a cutting edge provided on a second end of the hollow body, the second end being opposite to the first end; and
a cap configured to surround the second end of the dispenser so as to seal the dual chamber storage device.
15. The dual chamber storage device of claim 14 , wherein the aperture is sized and shaped to deliver a mixture of the first material and the second material in an amount of between about 1 microliters and 20 microliters.
16. The dual chamber storage device of claim 14 , wherein the cap is rotatingly connectable with the second chamber and non-rotatingly connectable with the first end of the dispenser; and
when the cap is rotated relative to the second chamber, 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.
17. The dual chamber storage device of claim 14 , wherein the first material is a lyophilized material or a material configured to be lyophilized and the second material is a liquid.
18. The dual chamber storage device of claim 14 , wherein the vent is positioned outside of the hollow body of the second chamber.
