Patent ID: 8714720

Claim:
An ink container for an inkjet print head, comprising: a substantially rigid body of polymer material, the body including: a base; and a side wall integrally formed with, and extending outwardly from the base around a perimeter of the base, the side wall having an exposed edge distal to the base, wherein the base and the side wall define a low pressure chamber, the body containing ink in the low pressure chamber, and the polymer material having moderate to high air permeability; a flexible film, sealed at the side wall exposed edge over the low pressure chamber, inwardly flexible in response to a decrease in pressure and ink volume in the low pressure chamber, and outwardly flexible in response to an increase in pressure and ink volume in the low pressure chamber; and a metal coated on a perimeter of the polymer body and on an outer exposed surface of the flexible film, the metal to form a metal coating configured to decrease the air permeability of the polymer body, the metal coating being formed from at least copper; wherein the metal coating includes multiple layers.
