The shipping container for a wide "bedsheet" type of ribbon for line printers can also double as the cartridge for the installed ribbon. Identification remains permanently with the ribbon, and potentially messy installation is avoided. Referring to Fig. 1, ends 1 of container 2 of rectangular cross section each rotatably support a pair of parallel cores 3 onto one of which is wound an inked ribbon (not shown) with the free end of the ribbon secured to the other core. The container 2 is separable along its length into two open-sided cartridges 2a, 2b of approximately equal volume by removal of a tear strip 2c. Upon separation, the two cartridges 2a, 2b are installed, in Fig. 2, between a pair of end plates 4, each having a pair of spring-biased hubs 5 each supporting a core end.
