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.
Core Innovation
The invention is a double chamber container that holds a first matter in a first chamber and a separate second matter in a second chamber before use. A plunger displaces a stopper and forces the second matter into the first chamber to mix with the first matter. The claimed configurations use an ultrasonic seal, a luer-lock tip, or a self-healing stopper as specified for each container.
The disclosed embodiments include side channels that allow fluid to flow around the stopper, environmental sealing of chamber contents, a luer-lock tip adapted to receive a needle or dispensing tip, and a self-healing stopper adapted to be pierced by needles multiple times. The described matters include lyophilized material and liquid diluent; mixing may produce a vaccine, medication, or epoxy.
Claims Coverage
The relevant claims include three independent claims, each covering a double chamber container that holds separate matters before use and uses a plunger to move the second matter into the first chamber for mixing. They distinguish the container by an ultrasonic seal, a luer-lock tip, or a self-healing stopper.
Ultrasonic-sealed double chamber container
A first chamber with a stopper and cover is coupled to a second chamber by an ultrasonic seal. The second chamber has a plunger, which displaces the stopper toward the cover and forces the second matter into the first chamber to mix with the first matter.
Double chamber container with a luer-lock tip
A first chamber with a stopper and luer-lock tip is coupled to a second chamber containing a plunger. Upon use, the plunger displaces the stopper toward the luer-lock tip and forces the second matter into the first chamber to mix with the first matter. The luer-lock tip is adapted to receive a needle or a dispensing tip.
Double chamber container with a self-healing stopper
A first chamber has a stopper at its first end and a self-healing stopper at its second end, and is coupled to a second chamber containing a plunger. Upon use, the plunger displaces the stopper toward the self-healing stopper and forces the second matter into the first chamber to mix with the first matter. The self-healing stopper is adapted to be pierced by needles multiple times.
The three independent claims cover separate storage of two matters and plunger-driven mixing, with distinct claimed configurations using an ultrasonic seal, a luer-lock tip, or a self-healing stopper.
Stated Advantages
Not explicitly described in patent.
Documented Applications
Mixing the first and second matters to produce a vaccine, medication, or epoxy.
Single-dose dispensing using a luer-lock outlet and multi-dose withdrawal through a self-healing stopper.
