First Claim
1. A dual compartment pouch comprising:
- front and back sheets of a flexible barrier film arranged in opposing face-to-face relation, each having an inner surface, a top edge, a bottom edge, and opposite side edges extending longitudinally from said top edge to said bottom edge;
an inner sheet of a flexible barrier film disposed between the front and back sheets and having a top edge, a bottom edge, and opposite side edges, the inner sheet defining first and second compartments within the pouch;
side seams extending longitudinally along said opposite side edges and joining the front and back sheets to the inner sheet;
a bottom seam extending transversely along said bottom edges and joining the front and back sheets to the inner sheet;
an opening formed in the inner sheet and providing communication between the first and second compartments;
a breathable membrane disposed on the inner sheet and covering said opening, said breathable membrane having a peripheral edge overlying the inner sheet and spaced from said side seams and bottom seam, the breathable membrane comprising a moisture vapor permeable, water-impermeable sheet material; and
a seam located at or adjacent the peripheral edge of the breathable membrane joining the membrane to the inner sheet.

Abstract
The invention provides a dual compartment pouch having first and second compartments that are separated from each other by an impervious inner sheet having a breathable membrane. The breathable membrane comprises a breathable material that is pervious to moisture and gases, and impervious to liquids as well as microorganisms. The breathable membrane allows a sterilizing gas to be introduced between the first and second compartments. The front and back sheets are sealed to the inner sheet to define the first and second compartments in which the inner sheet forms a common wall between the compartments. The breathable membrane is disposed towards a central portion of the inner sheet and is spaced apart from the seams joining the front and back sheets to the inner sheet. In one embodiment, a sterilized article is disposed in one compartment, and an absorbent packets are disposed in the other compartment.
