    • A thermal ink-jet pen cartridge having a rigid external frame member is fabricated from a rigid engineering plastic and an interior frame structure is attached thereto, formed of a softer, more ductile plastic material than the 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. The external frame member comprises polysulfone, while the interior frame structure comprises a polymer blend composition comprising (A) a copolymer of ethylene and methyl acrylate and at least one of (B) a polyester copolymer and (C) either a styrene-ethylene/propylene or a styrene-ethylene/-butylene-styrene block copolymer. 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.
    • 具有刚性外部框架构件的热喷墨笔筒由刚性工程塑料制成,并且内部框架结构附接到由比工程塑料更软,更具延展性的塑料材料形成。 墨水储存器由内部结构和一对由不透油墨的塑料材料形成并与内部构件材料相容的柔性袋膜限定,允许膜与内部构件接合以形成防漏接头 。 外部结构具有形成内表面的锁定特征。 当内部构件注射成型到外部构件时,熔融材料流入锁定构件中并围绕着锁定构件,将内部构件固定到外部构件上并抵抗熔融材料冷却时的收缩力。 墨水容器通过延伸穿过外部框架构件和内部构件的填充口通道填充。 该通道内衬较软的内部构件材料,并在油墨填充过程之后通过过大的球形压力密封在通道中。 外框架构件包括聚砜,而内框架结构包括聚合物共混组合物,其包含(A)乙烯和丙烯酸甲酯的共聚物和(B)聚酯共聚物和(C)苯乙烯 - 乙烯/丙烯中的至少一种 或苯乙烯 - 乙烯/丁烯 - 苯乙烯嵌段共聚物。 当经受用于印刷的油墨时,本发明聚合物组合物提供良好的化学和热稳定性和耐溶剂性。 此外,本发明的聚合物组合物是柔性的,并且与用于喷墨墨盒的各种聚合物组分具有优异的相容性和粘合性。
