摘要： A thermal ink-jet pen cartridge having a rigid external frame member fabricated of a rigid engineering plastic, and an interior frame structure attached thereto, formed of a softer, more ductile plastic material than the rigid engineering plastic. An ink reservoir is defined by the interior structure and a pair of flexible bag membranes formed of a plastic material impervious to the ink and compatible with the interior member material, allowing the membranes to be joined to the interior member to form a leak-proof joint The interior frame structure is fabricated from a polymer blend composition comprising (A) at least one polymer selected from the group consisting of a polyethylene and a copolymer of ethylene and an alpha-olefin and (B) at least one polymer selected from the group consisting of a polypropylene and a copolymer of propylene and ethylene, wherein (A) is different from (B). The present polymer compositions provide good chemical and heat stabilities and solvent resistance when subjected to inks used in printing. Further, the present polymer compositions are flexible and have excellent compatibility and adhesion to the various polymeric components used in the ink-jet cartridge.

摘要： A thermal ink-jet pen cartridge having a rigid external frame member fabricated of a rigid engineering plastic, and an interior frame structure attached thereto, formed of a softer, more ductile plastic material than an engineering plastic. An ink reservoir is defined by the interior structure and a pair of flexible bag membranes formed of a plastic material impervious to the ink and compatible with the interior member material, allowing the membranes to be joined to the interior member to form a leak-proof joint. The external structure has locking features formed into an interior surface. When the interior member is injection molded to the external member, the molten material flows into and around the locking features, securing the interior member to the external member and resisting the shrinkage forces as the molten material cools. The ink reservoir is filled through a fill port passageway extending through the external frame member and the inner member. The passageway is lined with the softer material of the inner member, and is sealed by an oversized ball press fit into the passageway after the ink filling process.

摘要： A method for filling an ink reservoir of an ink-jet cartridge. A cartridge is provided which includes a frame structure having an external frame structural member fabricated from a first rigid plastic material and an inner frame member fabricated from a second plastic material, the inner member lining an interior surface of the external frame member. The cartridge has first and second impervious membranes joined to the inner frame member to form, with the inner frame member, an ink reservoir for holding a supply of ink, and an ink fill port comprising a passage-way defined through the external frame member, the passage-way lined with said second material of said inner member and communicating with the interior of the reservoir. Ink is released into the reservoir from an ink supply through the fill port, which is then sealed. A method for forming a leak-resistent joint between the first and second plastic materials includes molding the second material into a predetermined first structure including a cavity defining the external periphery of an interior standpipe member, positioning the first structure into a mold for injecting the first material, injecting the first material in a molten state into the mold wherein the first material fills the outer periphery of the cavity and molds against the first structure to define the external periphery of the standpipe member, permitting the first material to cool, thereby forming a leak-resistent seal between the first and second materials about the standpipe member.

摘要： A method for joining two materials together to form a compact leak-resistant seal, particularly suited for use in thermal inkjet print cartridge ink reservoirs. The seal employs a shrink fit to clamp the two materials together. The method includes the steps of forming the first material into a desired first shot structure, placing the first shot structure in a second shot mold, and injecting the second material into the mold under adequate pressure and at an appropriate temperature. The second material has a high degree of mold shrinkage. Upon cooling, the second material shrinks tightly onto the first shot structure to form a molded joint which keeps air out and ink in when wetted and during normal shipping, storage, and operating conditions.
