Application fluid container for e.g. ink cartridges etc. has cylinder with internal fluid guide and projecting ribs to define applicator fluid reservoir slots

摘要

The container is located close to a fluid guide unit (4), between a fluid cartridge and an applicator. It has a cylinder (5a) with an internal aperture (5a1) for a fluid guide, and radially outward extending rib units. The ribs (5b) in each unit are parallel to an axial direction of the aperture at set intervals, so that ring-shaped applicator fluid reservoir slots (8) are defined between neighboring ribs.
