Abstract
An ink tank comprises a housing that defines a container for ink that is substantially free from a negative pressure producing material. In various embodiments, a non-porous capillary member is disposed in the container. The capillary member may be formed by part of the housing, for example, by a channel formed in a side wall of the housing. Alternatively, the capillary member may be a capillary tube. A wick may be situated at an outlet formed in the housing and may be held there by a retaining member, for example, a rib that extends from the housing. The housing may include a cover that allows the container to vent to atmosphere. The cover may include a vent hole that communicates with the container via a tortuous path. Part of the cover may comprise an air permeable material. The housing may also define a spillover area outside of the container.
