Abstract:
A recording head cap for capping an orifice plate of an ink jet recording head, which have a plurality of orifices on said orifice plate, during transportation and storage of said ink jet recording head, said recording head cap comprising:a solid elastic member for pressing an orifice-disposed face of a recording head; and an engaging section for pressing said solid elastic member against said orifice-disposed face and combining said solid elastic member with said recording head, wherein said orifice-disposed face is a flat plane, and wherein the hardness of said solid elastic member is 10 to 40 degrees as measured by an Asker C sponge hardness tester, and the repulsive load of said solid elastic member is damped by 20% or less under compressive elastic deformation of 10 to 60% to be 3 gf/mm2 or more after damping, so that said elastic member seals said plurality of orifices by the contact of said solid elastic member and said orifice-disposed face.
