Abstract
A storage container for temporarily storing an ink jet printhead cartridge during periods of non-use, the container including an improved nozzle capping mechanism which permits a variable range of forces to be applied to obtain the necessary sealing. The membrane is characterized by having, on one surface, a ribbed section which encircles the nozzle area to form a sealing perimeter. The other surface of the membrane has a shallow recess formed beneath the ribbed section, the recess providing for inward deflection along the ribbed area, the ribbed section maintaining an effective seal throughout a deflectable range. The arrangement solves a prior art problem of membrane buckling when excessive force is applied.
