Abstract

The present invention provides a peelable seal for a multi-chambered container including a first edge and a second edge. At least one of the first edge or second edge includes a stress bearing portion and a non-stress bearing portion.

Claims

1. A multichambered container comprising:

a first sidewall and an opposing second sidewall, the sidewalls permanently sealed along a common peripheral edge;

a peelable seal connecting the first sidewall and the second sidewall to form chambers in the container; and

the peelable seal having a length, the peelable seal having a serrated portion and a non-serrated portion along at least a portion of the length of the peelable seal, the serrated portion having a shorter length than the non-serrated portion.

2. The container of claim 1 wherein the peelable seal has a first edge, the serrated portion located on the first edge.

3. The container of claim 1 wherein the peelable seal has a first edge and a second edge, the serrated portion located on the first edge and the second edge.

4. The container of claim 1 wherein the serrated portion does not contact the peripheral edge.

5. The container of claim 1 further comprising a medical solution in the container.

6. The container of claim 1 wherein the container is a steam sterilizable container.

7. The container of claim 1 wherein each sidewall has a structure selected from the group consisting of a monolayer structure and a multiple layer structure.

8. The container of claim 1 wherein each sidewall further comprises a seal layer including a material selected from the group consisting of a homophase polymer and a matrix-phase polymer.

9. The container of claim 1 wherein the peel seal forms a chamber having a point, the serrated portion located at the point.

10. A multichambered container comprising:

a first sidewall and an opposing second sidewall;

a peripheral seal sealing the sidewalls along a common peripheral edge;

a peelable seal connecting the first sidewall and the second sidewall to form chambers in the container; and

the peelable seal having a length, the peelable seal having a serrated portion and a non-serrated portion along at least a portion of the length of the peelable seal, the serrated portion having a shorter length than the non-serrated portion, the serrated portion not in contact with the peripheral seal.

11. The container of claim 10 wherein the container is enclosed when the peel seal is separated.

12. The container of claim 10 wherein the peelable seal forms a chamber having a point, the serrated portion located at the point.

13. The container of claim 10 wherein the peelable seal extends from a corner of the container.

14. A multichambered container comprising:

a first sidewall and an opposing second sidewall;

a peripheral seal sealing the sidewalls along a common peripheral edge;

a peelable seal forming chambers in the container, the peelable seal having a length, the peelable seal having a serrated portion and a non-serrated portion along at least a portion of the length of the peelable seal, the serrated portion having a shorter length than the non-serrated portion; and

the peelable seal not in contact with the peripheral seal.
