摘要： A foam-filled cap sealing ink-ejecting nozzles of an inkjet printhead in a printing mechanism has a two-layer structure, with an outer skin layer of an elastomer, and a second foam core layer inside the skin. The skin defines a sealing lip that surrounds the nozzles when the cap is in a sealing position to avoid unnecessary drying of the ink. The skin has an interior surface that defines a cavity under the sealing lip. The foam core, located within the cavity, may be formed by expanding a foam preform or by injecting raw foam into the cavity. An insert may be molded into the cap structure for use in mounting the cap in the printing mechanism. An optional backing layer molded to the structure is used to attach a vent basin to the cap. A method of constructing this cap, and a printing mechanism having this cap, are also described.

摘要： A high deflection capping system has an elastomeric sealing member with a sealing lip that, when viewed in cross section, forms a smiling-shaped seal against an inkjet printhead to provide improved printhead sealing, particularly when sealing over surface irregularities on the printhead. This high deflection sealing member may be onsert molded onto a support frame. A series of these sealing lips being molded on a single flexible frame to simultaneously seal several adjacent inkjet printheads, with the flexible frame having a border region with one or more cap bases attached to the frame by plural suspension spring elements. The suspension spring elements have both cantilever and torsional characteristics which allow the bases to tilt and twist independent of one another to seal each printhead. Alternatively, the support frame may be designed to support only a single high deflection sealing member. A venting system is also provided with vapor diffusion handling capabilities.
