Abstract

A multiple chamber container for mixing and administering a plurality of products. The container has at least two chambers separated by a seal line. A frangible connector is situated between the two chambers for mixing the products contained within the chambers as desired. Each chamber has at least one port for filling of product into the chamber. The ports are located on the same exterior side of the container such that the chambers can be filled without folding the bag and by using existing filling equipment.

Claims

1. A container for housing two products comprising:

a container defining an interior between a plurality of exterior sides including at least a base, a top end and two lateral sides connecting the base and the top end, the lateral sides having a length greater than the base or the top end;

means for dividing the interior into only a first chamber and a second chamber, the first chamber having a substantially larger volume than the second chamber wherein one of the chambers further includes an integrally formed neck portion extending along an entire length of the other one of the chambers;

a valve for providing selective communication between the first chamber and the second chamber;

a first port in fluid communication with the first chamber on one of the exterior sides of the container; and

a second port in fluid communication with the second chamber on the same one of the plurality of exterior sides of the container as the first port wherein the exterior side having the first port and the second port is neither of the two lateral sides.

2. The container of claim 1 wherein the valve includes a frangible member.

3. The container of claim 1 wherein the exterior side including the first port and the second port is at the base.

4. The container of claim 1 wherein the one of the plurality of exterior sides including the first port and the second port is at the top end.

5. The container of claim 1 wherein the second port is constructed and arranged to disperse mixed solutions.

6. The container of claim 1 further comprising a third port in fluid communication with one of the chambers.

7. The container of claim 1 wherein the second chamber has a larger volume than the first chamber.

8. A container having a plurality of exterior sides defining an interior including at least a base, a top end and two lateral sides connecting the base and the top end, the lateral sides having a length greater than at least one of the base and top end for filling and storing two products prior to mixing the products into a mixture, the container comprising:

a first chamber capable of holding a first product that enters the first chamber through a first port;

a second chamber in fluid communication with the first chamber capable of holding a second product that enters the second chamber through a second port, the first chamber having a substantially larger volume than the second chamber wherein one of the chambers further includes an integrally formed neck portion extending along an entire length of the other one of the chambers; and

the first port and the second port located at the same exterior side of the container wherein the same exterior side having the first port and the second port is neither of the two lateral sides.

9. The container of claim 8 further comprising a container dividing seal between the first chamber and the second chamber.

10. The container of claim 8 further comprising a frangible connector between the first chamber and the second chamber.

11. The container of claim 8 further comprising an additional port in fluid communication with at least one of the chambers.

12. The container of claim 8 wherein the first port and the second port are at one of the plurality of exterior sides of the container wall at the base.

13. The container of claim 10 wherein the frangible connector is eccentric.
