Abstract

Disclosed is a double chamber container. The first chamber comprises a stopper coupled to a first end and a cover coupled to a second end. The second chamber comprises a plunger coupled to one end and an open second end. The first chamber is coupled to the second chamber such that the first end of the first chamber is coupled to the second end of the second chamber.

Claims (37)

1. A double chamber container, comprising:

in a pre-use configuration:

a first chamber adapted to hold a first matter and comprising a first end and a second end, wherein a stopper is positioned within the first end and a cover is coupled to the second end;

a second chamber adapted to hold a second matter separate from the first matter and comprising a first end and a second end, wherein a plunger is coupled to the first end of the second chamber and the second end of the second chamber is open; and

an ultrasonic seal coupling the first end of the first chamber to the second end of the second chamber;

wherein, upon use, the plunger is adapted to displace the stopper toward the cover and force the second matter into the first chamber to mix with the first matter.

2. The double chamber container of claim 1 , wherein the first chamber further comprises at least one side channel.

3. The double chamber container of claim 2 , wherein the at least one side channel is adapted to allow fluid to flow around the stopper when the stopper is adjacent to the at least one side channel.

4. The double chamber container of claim 1 , wherein, upon the first matter and the second matter mixing, a vaccine, a medication, or an epoxy is produced.

5. The double chamber container of claim 1 , wherein the first matter is a lyophilized material and the second matter is a liquid diluent.

6. The double chamber container of claim 1 , wherein contents of the first and second chambers are sealed from exposure to the environment.

7. A double chamber container, comprising:

in a pre-use configuration:

a first chamber adapted to hold a first matter and comprising a first end and a second end, wherein a stopper is positioned within the first end and a luer-lock tip is coupled to the second end; and

a second chamber adapted to hold a second matter separate from the first matter and comprising a first end and a second end, wherein a plunger is coupled to the first end of the second chamber and the second end of the second chamber is open;

wherein the first end of the first chamber is coupled to the second end of the second chamber;

wherein, upon use, the plunger is adapted to displace the stopper toward the luer-lock tip and force the second matter into the first chamber to mix with the first matter; and

wherein the luer-lock tip is adapted to receive a needle or a dispensing tip.

8. The double chamber container of claim 7 , wherein the first chamber further comprises at least one side channel.

9. The double chamber container of claim 8 , wherein the at least one side channel is adapted to allow fluid to flow around the stopper when the stopper is adjacent to the at least one side channel.

10. The double chamber container of claim 7 , wherein the first and second chambers are coupled together with an ultrasonic seal.

11. The double chamber container of claim 7 , wherein, upon the first matter and the second matter mixing, a vaccine, a medication, or an epoxy is produced.

12. The double chamber container of claim 7 , wherein the first matter is a lyophilized material and the second matter is a liquid diluent.

13. The double chamber container of claim 7 , wherein contents of the first and second chambers are sealed from exposure to the environment.

14. A double chamber container, comprising:

in a pre-use configuration:

a first chamber adapted to hold a first matter and comprising a first end and a second end, wherein a stopper is positioned within the first end and a self-healing stopper is coupled to the second end;

a second chamber adapted to hold a second matter separate from the first matter and comprising a first end and a second end, wherein a plunger is coupled to the first end of the second chamber and the second end of the second chamber is open; and

wherein the first end of the first chamber is coupled to the second end of the second chamber;

wherein, upon use, the plunger is adapted to displace the stopper toward the self-healing stopper and force the second matter into the first chamber to mix with the first matter; and

wherein the self-healing stopper is adapted to be pierced by needles multiple times.

15. The double chamber container of claim 14 , wherein the first chamber further comprises at least one side channel.

16. The double chamber container of claim 15 , wherein the at least one side channel is adapted to allow fluid to flow around the stopper when the stopper is adjacent to the at least one side channel.

17. The double chamber container of claim 14 , wherein the first and second chambers are coupled together with an ultrasonic seal.

18. The double chamber container of claim 14 , wherein, upon the first matter and the second matter mixing, a vaccine, a medication, or an epoxy is produced.

19. The double chamber container of claim 14 , wherein the first matter is a lyophilized material and the second matter is a liquid diluent.

20. The double chamber container of claim 14 , wherein contents of the first and second chambers are sealed from exposure to the environment.
