    • Printer ink cartridge and method of assembling same. The cartridge comprises a shell formed by a wall defining a cavity in the shell for storing ink. Disposed in the shell is a print head for ejecting ink drops through ink ejection orifices formed in the shell. The shell also defines an inlet port through the wall for allowing access to the cavity. An elastomeric seal or septum is matingly disposed in the port for sealing the port, the septum having a slit centrally therethrough for receiving an ink supply needle. A removable barrier is interposed between the cavity and the septum during manufacture of the cartridge. The barrier covers the port for isolating the ink in the cavity from the septum in order to avoid chemical interaction between the ink and the septum. During refilling of the cartridge, the ink supply needle is received through the slit and pushes the barrier from the port to allow refill ink to be supplied into the cavity.
    • 打印机墨盒及其组装方法。 盒包括由壁形成的壳体,该壳体在壳体中限定用于储存油墨的空腔。 设置在壳体中的是用于通过在壳体中形成的喷墨孔喷射墨滴的打印头。 壳体还限定通过壁的入口端口,用于允许进入空腔。 弹性体密封件或隔膜配合地设置在端口中用于密封端口,隔膜具有中心穿过其中的狭缝,用于接收供墨针头。 在盒的制造期间,可移除的屏障插入在腔和隔膜之间。 屏障覆盖用于将空腔中的墨与隔膜隔离的端口,以避免墨和隔膜之间的化学相互作用。 在重新填充墨盒期间,墨水供应针被接收通过狭缝并且从端口推动屏障以允许将再填充墨水供应到空腔中。
